TheGreekPhilosopherswaspublishedin1950,twoyearsbeforeitsauthor,W.K.C.Guthrie,waselectedthethirdLaurenceProfessorofAncientPhilosophyintheUniversityofCambridge.Itpredateshismonumental(andsadlyunfinished)six-volume A History of Greek Philosophy by more than a decade (thosevolumeswerepublishedbetween1962and1981)butisalwayslikelytobethemorewidelyreadofthetwo.Fewsuchbooksbearreadingmorethansixtyyearsafter their publication, particularly those that deal with so wide a topic andmanage to cover it with style and in not many more than 150 pages.Nevertheless,despitethegreatflourishingofscholarshipandtheappearanceofmanysimilarvolumesonancientphilosophysinceitwaswritten,thepaceandtoneofthisbookguaranteeitscontinuedinterest.Asitsauthorpointsoutattheoutset, the intendedaudienceare ‘undergraduates…readinganysubjectotherthanclassics’.AndGuthriewritesthroughoutwithcareandattentiontosuchanaudience,explainingtonon-specialistswhatthereistobefoundintheseancientauthorsandthinkers.Thetextskipsalongatapaceandneverletsthecomplexityof the ideasbeingdiscussedobstruct theprincipal aimof informing interestedreadersofwhattheGreekphilosopherswereupto,inamannerwhichGuthriethinksisfreefromthepotentiallydistortingeffectsoftheinterveningcenturiesofreceptionanddiscussionoftheirideas.Theaimistoinstructandinformandtheprimarymethodofinstructionisexpositionviaastoryofdevelopmentand,forthemostpart,progressovertheperiodbetweenThalesandAristotle.Althoughhehasinmindanaudienceunfamiliarwiththetextsintheiroriginal

language, Guthrie explains clearly and succinctly where necessary theimportanceofunderstandingtheprecisenuancesandconnotationsof thetermsand concepts under scrutiny. Indeed, he is insistent throughout on differencesbetweenhisworldandthatoftheGreekphilosophersandontheimportanceof

Page 10: The Greek Philosophers: from Thales to Aristotle

understanding what he calls the ‘cultural soil’ of their ideas. His Greekphilosophers, particularly the early Greek philosophers, are a peculiar andunusual bunch. He sees them as great pioneers in questions of science andphilosophy but pioneers whose faltering steps should be understood in theirpropercontext.Wemight,withsomecaveats,describeGuthrie’sapproachasacombination

of twoprincipalmethodsofphilosophicalhistoriography.On theonehand,hetakes fromAristotle the outlines of the history of Greek philosophy, buildingfrom Ionian natural philosophy through Socratic and sophistic approaches tohumanity andmorals to the great systems of Plato and thenAristotle himself.(Guthrie’sconfidence in theAristotelianaccountwasnot shakenby theattacklaunched on Aristotle’s value as a witness to his predecessors by HaroldChernissintwovolumespublishedin1935and1944.Guthrie’selegantretortin1957 is a useful statementof his overall attitude to thequestion.)Thegeneralstory is one of gradual progress and improvement, with Aristotle finallyharnessingthebestofnaturalphilosophywiththeimportanceofthemetaphysicsofformandteleologythatwasfirstseenbyPythagorasandthenrefinedbyPlatohimself,andcombiningthiswithadevelopedformofSocrates’interestinethicsandPlato’semphasisontheimportanceofpoliticalharmony.Theothersignificantmodeofanalysiscomesmorefromtheanthropological

approachestotheancientworldthathadmadeanimpactatthetimeGuthriewaswriting. (E. R.

For example, Anaximander wins plaudits for hisspeculativecosmologyandscientificadvances–Guthrie isquitehappy tocallAnaximander a scientist – but is nevertheless still unfortunately bound to a‘primitive’ notion of the universe as being a livingwhole, a notion ‘towhichanthropologists have found parallels among savage people all over theworld’(29).Sometimes,hisattitudetotheseGreekphilosophersisacuriousmixtureofadmiration and condescension.They are regularly applauded formaking earlystepsawayfromanaïveor‘primitive’outlookbutthenmarkeddownforbeingunable entirely to shake off the shackles of their intellectual inheritance.

Page 11: The Greek Philosophers: from Thales to Aristotle

Elsewhere, Guthrie is too quick to find fault and his judgement is surelyquestionable. For example, he diagnoses what he thinks are the ‘tiresome’arguments of the Eleatic philosopher Parmenides as stemming from anunfortunate logicalnaivety towhicheven‘the leastphilosophicalofus’wouldnotbeprone:‘OneideawhichtheGreeksatthisstagefounditdifficulttoabsorbwas thatawordmighthavemore thanonemeaning.Theirdifficultynodoubthadsomethingtodowiththeproximityoftheprimitivemagicalstageatwhichawordanditsobjectformedasingleunity’(44).CurrentunderstandingsofearlyGreekpoetryandevenphilosophers suchasHeraclitus showquiteclearly thatGuthrie’sdiagnosisisatbestamisunderstanding.Modernreaderswouldperhapsdo well to read such comments with a very critical eye. In short, we shouldcertainlyrecognisetheimportanceofGuthrie’sclearandconfidentinsistenceontheimportanceofculturalcontext,evenifwemightnotaccepthistendencytoattribute anything he finds mistaken or foolish to a legacy from ‘primitive’thought, nor the manner in which he is inclined to describe those traditionalsocieties.There are some heroes in Guthrie’s story. Pythagoras looms larger than he

mightinamoremodernaccountofthedevelopmentofGreekphilosophy,inpartbecauseGuthrie is relatively optimistic about the amount that can securely beattributed to theearliestphasesof thePythagoreanmovement.Pythagoras is achampion of order and of form, a distinctive voice in the otherwiseoverwhelminglymaterialisticoutlookofthePresocraticphilosophers.Socratesisa humanist ahead of his time and a defender of good sense in the face of ‘anatmosphere of scepticism’ encouraged by Presocratic natural philosophy andpeddledbythesophistswhoflockedtoAthensandbenefittedfromthelicencegenerated by a buoyant and democratic Athens. And Plato – perhaps mostsurprisingofall– isadefenderof‘theideaof thecity-stateasanindependentpolitical,economic,andsocialunit’(75)inthefaceofMacedonianconquestandimperialism.Aristotle is, forGuthrie, ‘anIonianwith thebloodofscientists inhisveins’(113),amanofrobustcommonsenseandthereforeaversetoPlato’sflights away from the everyday to a mysterious transcendent reality, but whonevertheless remained committed to some of the central tenets of Platonism,principallyteleologyandthepriorityofform.GuthrieeventakeshispictureofAristotle the scientist so far as to claim that Aristotle turned to practicalphilosophyintheEthicsandPoliticsonlyoutofasenseofduty;hewould,weare told,much rather have remainedwith ‘the delights of the laboratory’, buteven philosophers find their lives affected by the governance of the societyaroundthem(142).Thisunusualemphasisaside,it isworthremarkingthattheaccount of Aristotle in the final three chapters is a magnificent example of

Page 12: The Greek Philosophers: from Thales to Aristotle

clarityandconcision;Guthriemanagesinjustoverfortypagestocoverall themajor areas of Aristotle’s thought with a confident authority. (Consider, forexample, the accountofAristotle’s theoryofperception at 136–9: a topic thatcontinues togenerateagreatdealof interpretativecontroversy.)Therearealsosome important omissions from the story. In a text of this kind it is perhapsunderstandablethattherearerelativelyfewreferencestootherscholars,besidescourteous nods to his senior Cambridge colleagues F. M. Cornford and R.Hackforth(bothalsoLaurenceProfessors)andrelativelylittlesenseofscholarlydisagreement. But there are other choices worth emphasising. There is littleinterest in the methodological questions that arise from the difficulties ofinterpreting texts written in often oblique forms – verse, for example, ordialogues–orwhichsurviveonlyinfragmentsorlaterreports.Thereisabriefnote about the literary richness of the Platonic dialogues (111–12) but for themost part these concerns are set aside in favour of the pace of exposition.Guthrie also decides not to pursue the story of ancient philosophybeyond thetimeofAristotle,onthequestionablegroundsthattheHellenisticworldwasnot,afterall,purelyGreekanymore.Instead,andperhapsreflectingconcernsabouthisownage,Guthriesawitasaworldofindividualismanddespairinthefaceofincreasinglydominantinternationalpowers.AvolumeonHellenisticphilosophywasapparentlyplannedforinclusioninhislaterAHistoryofGreekPhilosophybuthewasunabletobeginworkonitbeforehisdeath.GuthrieconceivedofthestudyofancientphilosophyasabranchofClassics

1GREEKWAYSOFTHINKING

Toindicatethescopeandaimofthefollowingpagesitwillbebesttosayatoncethat they are based on a short course of lectures designed for an audience ofundergraduates who were reading any subject other than Classics. It wasassumed that thosewhowere listening knewnoGreek, but that an interest insomeother subject, such asEnglish,HistoryorMathematics (for therewas atleast one mathematician among them), or perhaps nothing more than generalreading,hadgiventhemtheimpressionthatGreekideaswereat thebottomofmuchinlaterEuropeanthoughtandconsequentlyadesiretoknowmoreexactlywhattheseGreekideashadbeeninthefirstplace.Theyhad,onemightsuppose,encounteredthemalready,butinaseriesofdistortingmirrors,accordingasthisor that writer in England, Germany or elsewhere had used them for his ownpurposesandtingedthemwiththequalityofhisownmindandage,or, itmaybe,wasunconsciouslyinfluencedbythemintheformulationofhisviews.SomehadreadworksofPlatoandAristotleintranslation,andmusthavefoundpartsofthempuzzlingbecausetheyaroseoutoftheintellectualclimateofthefourthcenturyB.C.inGreece,whereastheirreadershadbeenledbacktothemfromtheclimateofalaterageandadifferentcountry.Acting on these assumptions I tried, and shall now try for any readerswho

up certain important differences between the Greek ways of thought and ourown,which tend to be obscuredwhen (for example)Greek atomic science orPlato’stheoryoftheStateareuprootedfromtheirnaturalsoilintheearlierandcontemporary Greek world and regarded in isolation as the forerunners ofmodern atomic physics or political theory. For all the immense debt whichEurope,andwithEuropeEngland,owetoGreekculture, theGreeksremain inmany respects a remarkably foreign people, and to get inside their mindsrequires a real effort, for itmeans unthinkingmuch that has become part andparcelofourmentalequipmentsothatwecarryitaboutwithusunquestioninglyandforthemostpartunconsciously.InthegreatdaysofVictorianscholarship,whentheClassicswereregardedasfurnishingmodels,notonlyintellectualbutmoral, for the English gentleman to follow, there was perhaps a tendency tooveremphasizesimilaritiesandlosesightofdifferences.Thescholarshipofourownday,inmanyrespectsinferior,hasthisadvantage,thatitisbasedbothonamore intensive studyofGreekhabitsof thought and linguisticusageandonamoreextensiveacquaintancewiththementalequipmentofearlierpeoplesbothinGreeceandelsewhere.Thanksinparttotheprogressofanthropology,andtotheworkofclassicalscholarsacuteenoughtoseetherelevancetotheirstudiesofsomeoftheanthropologists’results,wecanclaimwithoutarrogancetobeinabetter position to appreciate the hidden foundations of Greek thought, thepresuppositionswhich theyaccepted tacitlyaswe todayaccept theestablishedrulesoflogicorthefactoftheearth’srotation.Andhereitmustbesaidfrankly,thoughwithnowishtodwellonadifficulty

It will therefore be necessary sometimes to introduceGreek terms, and explain as clearly as possible how they were used. If thisshouldhave theeffectofenticingsometo learnGreek,orrefurbishanyGreekwhichmayhavebeen learnedat schoolanddropped in favourofother things,that will be all to the good. But the present account will continue on theassumptionthatanyGreekwordusedneedstobeexplained.Beforegoing further,a fewexampleswouldperhapsbehelpful tobringout

Page 17: The Greek Philosophers: from Thales to Aristotle

Now the original meaning of dike may have been literally a way or path.Whetherornot that is itsetymologicalorigin, itsearliestsignificanceinGreekliterature is certainlynomore than theway inwhich a certain classof peopleusuallybehaves,orthenormalcourseofnature.Thereisnoimplicationthatitisthe rightway, nor does theword contain any suggestion of obligation. In theOdyssey,whenPenelopeisremindingtheservantswhatagoodmasterOdysseuswas,shesaysthatheneverdidorsaidanythingthatwascrueloroverweening,nordidhehavefavourites, ‘as is thedikeof lords’– i.e. it is theway theyarewont tobehave.WhenEumaeus theswineherdentertainshismasterunawares,he apologizes for the simplicity of his fare by saying: ‘What I offer is little,thoughwillinglygiven,forthatisthedikeofserfslikemyself,whogoeverinfear.’ It is, he means, the normal thing, what is to be expected. Describing adisease, the medical writer Hippocrates says, ‘Death does not follow thesesymptomsinthecourseofdike’,meaningsimply,‘doesnotnormallyfollow’.1Itwaseasyforsuchawordtoslipfromthispurelynon-moralsenseofwhat

Indeed a kind of petrified relicremainedthroughoutintheuseoftheaccusative,diken,asaprepositiontomean‘like’or‘afterthemannerof’.At the conclusion of the attempts to define ‘justice’ in the Republic, after

several definitions have been rejected which more or less correspond to ournotionsofwhatwemeanbytheword,theonewhichisfinallyacceptedisthis:justice, dikaiosyne, the state of the man who follows dike, is no more than‘minding your ownbusiness’, doing the thing, or following theway,which isproperlyyourown,andnotmixingyourselfupinthewaysofotherpeopleandtryingtodotheirjobsforthem.Doesitsometimesseemtousratheramouselikeresulttobebornofsuchmountainsofdiscussion?Ifso,itmaymakeitalittlemoreinterestingtoreflectthatwhatPlatohasdoneistorejectthemeaningsofthewordwhichwerecurrent inhisownday, andwithapossiblyunconscioushistoricalsensetogobacktotheoriginalmeaningoftheword.Itwasrootedinthe class-distinctions of the old Homeric aristocracy, where right action wassummedupinaman’sknowinghisproperplaceandstickingtoit,andtoPlato,whowas founding a new aristocracy, class-distinctions – based this time on a

It is not therefore surprising that when the philosophersgeneralizedthenotiontoincludetheproperperformanceofhisfunctionbyanyhuman being as such, its connexion with knowledge should have persisted.Everyone has heard of the ‘Socratic paradox’, his statement that ‘virtue isknowledge’.Perhapsitbeginstolookalittlelessparadoxicalwhenweseethatwhat itwouldnaturallymean toa contemporarywasmore like: ‘Youcan’tbeefficientunlessyoutakethetroubletolearnthejob.’ThethirdexampleistheGreekwordforgod–theos.Whenwearetryingto

Itmaybe thatmagicandwitchcraftwere,asIhavesaid, rife inPlato’stime. It is equally important that he condemned them roundly. Ifwhat I havebeen saying leaves the impression that the Greek thinkers were a kind ofsuperiormedicine-menwith a dash of rational thought thrown in, itwill havebeen worse than useless. What it should do is to give some idea of thedifficulties with which they had to contend, and so if anything heighten ourappreciationoftheirachievementswhenwecometothem.MoreoverthehistoryofGreekthoughtisinoneofitsaspectstheprocessofemancipationfromsuchpopular preconceptions, many of which can be studied to-day among thepeasants of modern Greece, and this in itself made some reference to themadvisableasanintroduction.Inmakinganhistoricalstudyofthephilosophyofacertainepoch,wemustof

Returningtothefirsttwobranchesofphilosophy–themetaphysicalandtheethical – some philosopherswill be equally interested in both and succeed incombining them in one single, integrated system. That was the aim of Plato,whosephilosophicpurposewastocombattwocomplementarytendenciesofhisage:(i)intellectualscepticism,whichdeniedthepossibilityofknowledgeontheground that therewereno lastingrealities tobeknown: (ii)moralanarchy, theviewthattherewerenopermanentanduniversalstandardsofconduct,nohighercriteria of action than what happened to seem best to a particular man at aparticular moment.

Europeanphilosophy,inthesenseofanattempttosolvetheproblemsoftheUniverse by reason only, as opposed to the acceptance of purely magical ortheologicalexplanations,beganintheprosperouscommercialcitiesofIonia,onthecoastofAsiaMinor,intheearlysixthcenturyB.C.Itwas,asAristotlesaid,the product of an age already providedwith the necessities for physicalwell-beingand leisure, and itsmotivewas simplecuriosity.The IonianorMilesianSchool is representedby thenamesofThales,Anaximander andAnaximenes,and there is thismuch justification for calling it a school, that all three werenativesofthesameprosperousIoniancityofMiletus,theirlifetimesoverlapped,andtraditionatleastdescribedtheirrelationsasthoseofmasterandpupil.The object of their searchmay be described in twoways. They looked for

somethingpermanent,persistingthroughthechaosofapparentchange;andtheythoughtthattheywouldfinditbyaskingthequestion:‘Whatistheworldmadeof?’Theworldasoursensesperceiveitseemsrestlessandunstable.Itexhibitscontinualandapparentlyhaphazardchange.Naturalgrowthmayproceedormaybe thwarted by blind external forces. In any case it is followed by decay andnothing lasts for ever.Moreoverweobserve an apparently infinite pluralityofunrelatedobjects.Philosophystartedinthefaiththatbeneaththisapparentchaosthereexistsahiddenpermanenceandunity,discernible,ifnotbysense,thenbythemind.Thisstatementappliesofcoursetoallphilosophy.Asamodernwriteronphilosophicalmethodhasputit:‘Thereseemstobeadeep-rootedtendencyin the human mind to seek … something that persists through change.Consequently the desire for explanation seems to be satisfied only by thediscoverythatwhatappearstobenewanddifferentwasthereallthetime.Hencethe search for an underlying identity, a persistent stuff, a substance that isconserved in spite of qualitative changes and in termsofwhich these changescanbeexplained.’1Thatdescriptionofthephilosophicmindmighthavebeenwrittenspeciallyfor

the Milesians. They were already philosophers, and the basic problems ofphilosophy change little through the ages.Central is the faith that beneath theapparent multiplicity and confusion of the universe around us there exists afundamentalsimplicityandstabilitywhichreasonmaydiscover.Secondly, it seemed to the earliest speculators that this stability must be

sought in the substance of which the world was made. This is not the onlypossibleanswer.Itmayequallybesupposedthatthematerialcomponentsoftheworld are in a constant flux of decay and renewal, are manifold andincomprehensible,butthatthepermanentandcomprehensibleelementliesinitsstructureorform.Ifnewmatterasitcomesalongfitsitselfalwaystothesamestructure, it is thestructure thatwemust try tounderstand.InGreeceitself the

Page 29: The Greek Philosophers: from Thales to Aristotle

champions of form against matter were to have their turn. At the beginning,however,thequestionaskedwas,initssimplestterms:‘Whatistheworldmadeof?’ThalesofMiletussaidthatitwaswater,ormoisture,ananswerwhichmightopenupall sortsof interestingpossibilities,were itnot thatweknowscarcelyanythingmore about his views and can only conjecturewhatwas the train ofthoughtwhichledhimtohisconclusion.Themostobviousexplanationseemstobe that water exhibits itself naturally to the senses, without any apparatus ofscientific experiment such aswas not then available, in the three forms solid,liquidandgaseous,asice,waterandsteam.Thisisaccordinglytheexplanationwhichoccursmostreadilytomodernscholars,butitisinterestingthatAristotlehasaquitedifferentsuggestion.He, too,wasguessing–whateverThalesmayhavewrittenwasalreadylostinhisday–buthewasatleastaGreekandnearertoThalesthanourselves.Iwanttosuggestsomereasonswhyhemayhavebeenright,butthisisatopictowhichwehadbetterreturnwhenwehavelookedattheviewsoftheothertwoMilesians.BeyondhisstatementthattheunderlyingsubstanceoftheUniverseiswater,

He saw this

presentworldasawarringconcourseofoppositequalities,ofwhichfourwereprimary – hot and cold, wet and dry. Theworld-process is a cyclic one. Thesun’sheatdriesupwater,waterputsoutfire.Onaworld-scaleitisobservableinthecycleoftheseasons,andthoughoneorotheroftheoppositesmayprevailfora time, the balance is constantly being restored.Now since the essential thingabout these qualities is their mutual opposition, it follows that the primarysubstanceoftheUniversecannotbecharacterizedbyanyoneofthem–cannot,Anaximanderwouldhavesaid,beanyoneofthem,foritismostunlikelythatatthis early stage of thought quality and substance were differentiated. HadAnaximanderbeenaskedwhether,whenhespokeashedidof‘thehot’or‘thecold’,hemeantasubstanceoraquality,hewouldprobablynothaveunderstoodthequestion.If then,asThaleshadsupposed,allwereoriginallywater,or‘the

His was an age when thesupernatural was still taken for granted, when the forces of nature wereattributedtotheactionsofanthropomorphicgods,aZeusoraPoseidon,andtheorigin of the Universe had hitherto been sought in grotesque stories about asexualunionofheavenandearth,conceivedasvastprimevaldeities,andtheirforcing-apart by another gigantic spirit. With Anaximander human reasonasserted itself and produced what, right or wrong, was for the most part anaccountinpurelynaturaltermsoftheoriginoftheworldandlife.FromAnaximenes,theremainingmemberoftheMilesianSchool,wehaveno

connected account of cosmogony, but a new claimant for the title of primarysubstance. This is air (Greekaer, which in ordinary speech – and there is noquestionatthisstageofatechnicalscientificterminology–meantbothairandmist or fog). In its natural, or what Anaximenes called its most evenlydistributed state, it is the invisible atmosphere, but it is capable of beingcondensed into mist and water, and so, he claimed, still further into solidsubstances like earth and stones.When it becomes still rarer, it also becomeshotterandturnsintofire.Hischiefinterestseemstohavelainindiscoveringanaturalprocessbywhich itmightbesupposed that thechanges in theprimarysubstance take place, whereby our manifold world comes into being.Anaximander’s word for the process which gave rise to our world had been‘separating-out’,butitcouldfairlybesaidthatthiswasnomorethanabrilliantconjecturewhich couldnot beverified in anyknownprocessof nature.For itAnaximenes substituted the observed fact of condensation and rarefaction,whereby we see air reduced to moisture and vice versa. To illustrate theconnexion of rarefactionwith heat and condensationwith cold he pointed outthatifwebreathewithourlipsnearlyclosedthebreathemergescold,whereasif

He said that in its purest and rarest form of all, the air which is theultimateworld-substance is also the stuff of life.A small portion of this soul-stuff, which properly belongs by its nature to the outermost reaches of theUniversebeyondtheadulteratedatmospherewhichwebreathe,isimprisonedinthebodyofeachanimalorhumanbeing,andformsitssoul.‘Oursoul’,saidoneofhisfollowers,‘isair,hotterthantheairoutsideus,thoughmuchcolderthantheairatthesun.’Thismanalsoexpressedthesamethingbysayingthatman’ssoulis‘asmallpartofthegod’,thegodbeingtheUniverse,whichwethuslearnisstillthoughtofbythesemenasbeingalive.Foralltheirastonishingfreedomfromtheologicalpreconceptions,thisoneidearemained.Itwasindeedalegacyfrompre-rationalthought,forthismaterialconceptionofthesoulasairorbreathisofcourseaprimitiveonetowhichanthropologistshavefoundparallelsamongsavagepeoplesallovertheworld,anditwascertainlycoupledamongtheearlierGreekswiththeideathattheworldasawholewasalivingcreature.Neverthelessfortheseearlyscientiststherewasaspecialreasonwhyitshould

we must disabuse our minds of the atomistic conception of dead matter inmechanicalmotion and of the…dualismofmatter andmind.’Aristotle,whowasalreadycriticizing the Ionians for (as it appeared tohim) ‘lazily shelving’thequestionof themotivecause, remarks inoneplace,withoutcomment, thatnoneofthemmadeearththeprimarysubstance.Therewassurelyagoodreasonforthis.Theywantedasubstancewhichwouldexplainitsownmovement,asinthose early days it was still possible to imagine it doing. One thought of theceaseless tossing of the sea, another of the rushing of the wind, and on the

Page 33: The Greek Philosophers: from Thales to Aristotle

threshold of rational thought the natural explanation of their apparently self-causedmovementwas that theywere eternally alive. Thuswe find that all ofthem,while inotherrespectsavoiding the languageofreligionandcompletelydiscardingtheanthropomorphismoftheirtime,yetappliedthenameGodor‘thedivine’ to their primary substance. So Anaximander called his apeiron andAnaximenes the air. Thales is creditedwith the dictum: ‘Everything is full ofgods’,whichAristotleinterpretedasmeaningthat‘soulismingledinthewhole’.Thestuffoftheworldmustbethestuffoflife,andthatiswhyIthinkthereismoretobesaidforAristotle’sconjecturesaboutthereasonforThales’schoiceofwaterthanmoderncommentatorsareinclinedtoallow.Hiswordsare:‘Hegotthenotionprobablyfromseeingthatthenutrimentofallthingsismoist,andthatheatitselfisgeneratedbythemoistandkeptalivebyit…andthatthesemenofall creatureshas amoist nature, andwater is theoriginof thenatureofmoistthings.’ThelinesofthoughtsuggestedbyAristotlearethosewhichlinkupwaterwith

theideaof life: themoisturewhichisanecessarypartoffoodandsemen,andthefact thatvitalheat, thewarmthofa livingbody, isalwaysadampwarmth.(The connexion between heat and life, an obvious fact of experience, wasinsistedonby theGreeks as essential and causativemore than it is to-day.) Ifthat was Thales’s idea, we find it explicitly paralleled by Anaximander whoaccountsfortheoriginoflifebytheactionofheatonwateryorslimymatter.Seeingthatthesethinkersonlyaskedtheirsinglequestion:‘Whatistheworld

to South Italy round about 530 B.C., where he settled and founded hisbrotherhood in the townofCroton.For political reasons theywere persecutedanddispersed,andbythefifthcenturyscatteredPythagoreancommunitieswereto be found in various parts ofGreece.To say nothing about the Pythagoreantraditionwould be to give a very one-sided view ofGreek philosophy and toomitsomething thatwasapotent influenceon themindofPlato.Yet itwouldperhapsdefeatourpresentpurposetodevotemuchspacetothemhere,owingtotheobscuritywhichenvelopsmuchoftheirdoctrineandtheirhistory.For this obscurity there are good reasons. Among the Pythagoreans, the

motiveforphilosophywasnotwhatithadbeenfortheIonians,simplescientificcuriosity.Theywereareligiousbrotherhood,andthishadcertainconsequences.Someatleastoftheirdoctrineswereheldtobesecret,andnottobedivulgedtothe profane. The founder himself was canonized, or regarded as semi-divine.Thismeant in the first place that a haze ofmiraculous legend gathered abouthim, from which it is difficult to disentangle the life and teaching of thehistorical Pythagoras. In the second place it was considered a pious duty toascribeanynewdoctrinetothefounderhimself,andconsideringthattheschoolhad a long history, including a particularly flourishing revival among theRomansinthetimeofCicero,itisobviouslydifficulttofindoutjustwhatwerePythagoras’sownbeliefsorthoseoftheschoolinitsearlydays.On its religious side, the core of Pythagoreanism was a belief in the

But the originality ofPythagoras is seen when we ask what are the means whereby the aim ofpurificationandunionwiththedivinemaybeattained.Hithertopurityhadbeensoughtbyritual,andtheobservanceofmechanicaltaboossuchastheavoidanceofcorpses.Pythagoras retainedmuchof this,butaddedawayofhisown, thewayofthephilosopher.The doctrine of the kinship of nature, which may be said to be the first

That is, the emphasis laid by Pythagoras on form orstructureastheproperobjectofstudy,togetherwithanexaltationoftheideaoflimit. If, as a classical professor recently stated in his inaugural lecture, acharacteristic mark of the Greeks is their preference for ‘the intelligible,determinate,mensurable,asopposedtothefantastic,vagueandshapeless’,thenPythagoraswastheforemostapostleoftheHellenicspirit.ThePythagoreans,asconvinced moral dualists, drew up two columns under the headings of goodthingsandbadthings.Inthegoodcolumn,alongwithlight,unityandthemale,camelimit;inthebadcolumn,withdarkness,pluralityandthefemale,isplacedtheunlimited.ThereligionofPythagorasembodied,aswehaveseen,akindofpantheism.

In short theworldmay becalled akosmos, an untranslatablewordwhich combined the notions of order,fitness, and beauty. Pythagoras is said to have been the first to call it by thisname.Pythagoras,beingbynatureaphilosopher,arguedthatifwewanttoidentify

widest influence over his thought and to have been the foundation of hismathematical philosophy, was in the field of music. He found out that thoseintervals of the musical scale which are still (I believe) called the perfectconsonancescanbeexpressedarithmeticallyasratiosbetweenthenumbers1,2,3and4.Thesearethenumberswhich,addedtogether,make10,andthenumber10,inthecuriousPythagoreancombinationofmathematicsandmysticism,wascalledtheperfectnumber.Itwasillustratedgraphicallybythefigurecalledthetetraktys,i.e. .Theoctaveisproducedbytheratio2:1,thefifth3:2,andthefourth4:3.Nowifonedidnotknowthis,itisnotthesortofthingthatwouldoccur to onewhile playing the lyre, and perhaps picking out the noteswith acertain amount of trial and error. The discovery lay in the existence of an

inherentorder,anumericalorganizationwithinthenatureofsounditself,anditappearedasakindofrevelationconcerningthenatureoftheUniverse.The general principle which it was taken to illustrate was that of the

imposition of limit (peras) on the unlimited (apeiron) to make the limited(peperasmenon).Thiswas the general Pythagorean formula for themaking oftheworldandallthatitcontains,anditwascoupledwiththemoralandaestheticcorollary that limitwas good and the unlimited evil, so that the imposition oflimitandtheformationofakosmos,whichtheyclaimedtoseeintheworldasawhole,wasevidenceofthegoodnessandbeautyoftheworldandanexampletobe followedbymen.Owing toPythagoras’sdiscovery,musicprovided forhisfollowersthebestinstanceofthisprincipleatwork.Itssuitabilitywasenhancedbythebeautyofmusic,towhichPythagoraslikemostGreekswassensitive,forthewordkosmoscarriedtoaGreekthesuggestionofbeautyaswellasorder.Itwas thus further evidence for the equation of limit with goodness that itsimpositionon thefieldofsoundbroughtbeautyoutofdisharmony.Thewholefieldofsound,then,rangingindefinitelyinoppositedirections–highandlow–isaninstanceoftheunlimited.Limitisrepresentedbythenumericalsystemofratiosbetweenconcordantnoteswhichreducesthewholetoorder.Itismarkedoutaccordingtoanintelligibleplan.Thisplanisnotimposedonitbyman,buthas been there all the time awaiting his discovery.

The system so defined still contains the unlimitedelementintheblankintervalsbetweenthenotes;buttheunlimitedisnolongeran orderless continuum: it is confined within an order, a kosmos, by theimpositionoflimitormeasure.’This process, grasped here in a single striking instance, the Pythagoreans

for this. First, his own temperament made him delight in spectacular andparadoxicallanguage.Hemaygiveusstraightforwardparadox,like‘Goodandevil are one’, or again a fascinatingbut tantalizing image, such as: ‘Time is achildplayingdraughts;thekingdomisachild’s.’Secondlyheisdifficultbecausethoughtwith him had reached a peculiarly difficult stage.He could no longeracceptthesimpleIoniancosmogonies,norfinditeasyandnaturaltoconfinelifeandthought in thestrait-jacketofmaterialsubstance.Theywereclearlyduetoburstitverysoon.Thebreakcameaboutinastrangeway.Itwasultimatelyduetotheworkofa

were the only realities; for Parmenides, movement was impossible, and thewhole of reality consisted of a single, motionless and unchanging substance.This extraordinary conclusion he reached by a train of thought no lessextraordinary.There is a sentence, the authorship ofwhich I cannot remember,which has

I am.’Of course in ordinary speech itwas used in its quite different sense ofhaving a certain quality, as to be black, cold etc., but thiswas a difference towhichnoonehadasyetdevotedanyconscious thought. Inmodern terms, thedifferencebetweentheexistentialandthepredicativeuseoftheverbhadnotyetbeenelucidated.ToParmenides, the first to reflect consciouslyon the logicofwords, it seemed that tosay thata thing is couldandshouldmeanonly that itexists, and this thought came to himwith the force of a revelation about thenatureofreality.Hiswholeconceptionofthenatureofrealityspringsfromtheattribution of this single, metaphysical force to the Verb ‘to be’. The Ionianphilosophershadsaidthattheworldwasonething,butbecamemany.But,saidParmenides,hasthisword‘become’anyrealmeaning?Howcanathingbesaidtochange,asyousaye.g.thatairchangedintowaterandfire?Tochangemeans‘tobecomewhat it isnot’,but tosayofwhat is that it isnot issimplyuntrue.Whatiscannotnotbeanything,for‘nottobe’meanstovanishoutofexistence.Thenitwouldnolongerbewhatis,but that issomethingwhichwasassumed,andhadtobeassumed,fromthebeginning.TheoneandonlyinitialpostulateofParmenideswasthat‘itis’,i.e.onesinglethingexists.Therestfollowed.It may sound like nonsensical playing with words, but it was taken very

seriously at the time, and it was only Plato in his full maturity who, in thedialogue calledThe Sophist, cleared up the point that although they used thesameword‘is’,Parmenidesandthepeopleagainstwhomhewasarguingmeanttwodifferentthings.Atthetimehisdoctrineseemedunanswerable,andstrangeconsequences followed. All change and movement were unreal, because theywouldinvolvewhatisbecomingwhatitisnotorwhereitisnot,andtosayofwhat is ‘It isnot’ isnonsense.Movementwas impossible fora second reason,also,thattherewasnosuchthingasemptyspace.Spacecouldonlybedescribedas‘wheretherealthing,thatwhichis,wasnot.’Butwhereyouhavenotgotthatwhichis,youobviouslyonlyhavethatwhichisnot,i.e.whatdoesnotexist.Therealworld,then,allthatis,mustbeachangeless,immovablemassofone

abstract thought, set themindworkingwithout reference toexternal facts, andexalted its resultsabove thoseofsense-perception. In this theGreekswereaptpupils,somuchsothataccordingtosometheirgeniusforabstractthoughtand

That particular question isunimportant and indeed unanswerable, seeing that we are still dealing with aperiodbeforethematerialandthenon-materialhadbeendistinguished.Whatisimportantisthathisrealitywasnonsensible,onlytobereachedbythought.ToPlatothedistinctionbetweenmaterialandspiritualwasplain.Yetheexpressesitfarmoreoftenbythewords‘sensible’and‘intelligible’.Parmenideswasthefirsttoexalt the intelligibleat theexpenseof thesensible,andconsequently tocallhim–ashehasbeencalled–thefatherofmaterialismisaboutasmisleadingasitcouldbe.Fromnowon,anyphilosophywhichmaintainedthatthemanifoldworldhad

Parmenides haddealtadeath-blowtomaterialmonismoftheIoniantype.Thefirstreactionwasthat theworldofappearancesmustatallcostsbesaved.Men’scommonsenserevoltedandsaid that the familiar thingswhichwecanseeand touchmustbereal.Sincethiscouldnolongerbecombinedwithabeliefinaprimalunity,theydenied that part of Parmenides’s premise which said that reality wassubstantially one. The immediately following philosophers are pluralists. NotuntilthegreatestofallGreekthinkers,Plato,dowefindonewhoagreedthatnomore than a quasi-existence could be ascribed to the changingworld of rocksand plants and animals, and sought reality and unity alike in aworld beyondspace and time. And though Plato was much influenced by Parmenides, andwrote of him with the greatest respect, there were by that time many otherinfluencesaswellthathelpedtomouldhisthought.The pluralists are represented by Empedocles, Anaxagoras, and the atomic

philosophyofDemocritus.Empedoclesisanintriguingfigure,acombinationofphilosopher, religious mystic on Pythagorean lines, and magician or wonder-worker. The Western Greek world, the home of Pythagoreanism, tended toproduce such combinations, andEmpedocles’s homewas atAcragas inSicily.Nootherageorcountrycouldhave thrownupsuchaphenomenon.Heclaimsthathisknowledgeisthekeytopowerovertheforcesofnature,thatbyitmencanarrest thewinds,makerain,andevenbringbackthedeadfromHades.Hewasafirmbelieverinthetransmigrationofsouls.Allthiswasanessentialpartof him and cannot be separated fromhis philosophy,which yetwas a seriouscontribution to thought and the first attempt to escape the logical net of

We cannot for instance go into Empedocles’s explanation of themechanismof sensation, interesting though it is.But it is tempting tomentionone of the stranger results of Empedocles’s system on account of its intrinsicinterest, namely that when he came to details it involved him, as it were byaccident (for there was no question of scientific observation), in an almostDarwiniantheoryofnaturalselection.Heisanaturalphilosopherinthis,thatinhisworld there is no creative god, nomind adapting organisms to a purpose.Living creatures, like other natural bodies, have originated in purely chancecombinations of the elements.He had to explain thereforewhy their structureandorganssimulatedsowelltheappearanceofpurpose.Eyesandears,feetandhands,digestiveorgansandsoforthseemsoadmirablyadaptedforthefunctionswhich they have to perform that it is difficult not to believe that they weredesigned with these in view.

Atomism of course gains a special interest from its anticipation of modernviews.ItishardlyanexaggerationtosaythatthetheoryofDemocritusremainedinessentialsunchangeduntilthenineteenthcentury.Itisneverthelessimportantto remember the complete absence in classical Greece of the apparatus ofscientific experiment which has led to the discoveries of modern times, andenabled each one to be tested. Why the Greeks, for all their brilliance ofintellect,madeatthistimesolittleuseofexperimentalmethods,andnoprogressat all in the inventionofapparatus forcontrolledexperiment, is acomplicatedquestion. Aristocratic tradition and the presence of slaves no doubt hadsomethingtodowithit,butarescarcelyinthemselvesasufficientexplanation.TosomesmallextentthoseintheIoniansuccessionmadeuseofobservation,butonlyspasmodicallyuntilthetimeofAristotle,andofcontrolledexperimenttheyhad no idea. Their legacy lies elsewhere, in their astonishing powers ofdeductivereasoning.Aswitheveryoneelseatthatperiod,thethinkingoftheatomistswascarried

In taste, sweet thingsare made of smooth atoms, whereas harsh or bitter flavours are caused byhooked or sharp-pointed atoms which tear their way into the body makingminute excoriations on the tongue. As late as 1675, we find this notion

Page 49: The Greek Philosophers: from Thales to Aristotle

persisting.AFrenchchemist,Lémery,wroteatthatdate1:‘Thehiddennatureofa thing cannot be better explained than by attributing to its parts shapescorrespondingtoalltheeffectsitproduces.Noonewilldenythattheacidityofaliquidconsistsinpointedparticles.Allexperienceconfirmsthis.Youhaveonlytotasteittofeelaprickingofthetonguelikethatcausedbysomematerialcutintoveryfinepoints.’Colours were explained by the various positions of the atoms forming the

Thusalthough sight is a matter of direct contact between atoms and atoms, it ispossibletobedeceivedaboutthenatureofanobjectseenatadistance,becausethe material image which passes from it to the eye may become distorted ordamagedontheway.Themechanicsofsensationwerepursuedintoconsiderabledetail, and an extraordinary ingenuity was shown in trying to explain all itsvarieties without recourse to any other hypothesis than that of directmaterialcontact.One thingof coursewas a fundamental necessity to the atomicworld-view.

Theremust be empty space for the atoms tomove about in. The hallmark ofDemocritus’s thought, as Aristotle noted approvingly, was a determination toaccountforapparentfactandnotbeledastraybyabstractargument.HencehesaidthatParmenides’sdenialoftheexistenceofvoidcouldnotbeupheld.Itwascontrarytocommonsense.Awarehoweverthathewasflyinginthefaceofthatgreat authority, he made his denial with a kind of schoolboy daring, foraccordingtoAristotleheputitintheform:‘Whatisnotdoesexist,nolessthanwhat is.’Ifmaterialatomsweretheonlyrealsubstance, thenemptyspacewasnot real in the samesense.Dimlyaware that theremustbe somewayout, theatomistsdidnotyetcommandalanguagecapableofsuchaphraseas‘notinthesamesense’,andparadoxwastheironlyresource.They seem tohave thought that, given infinite empty spacewith an infinite

numberofmicroscopicbodieslooseinit,thebodieswouldinevitablymove,and

Page 50: The Greek Philosophers: from Thales to Aristotle

move aimlessly in any direction. This would naturally lead to collisions, andthese to entanglements and combinations, since the atomswere of all sorts ofshapes,includinghookedandbranched.Thusagglomerationsofperceptiblesizeweregraduallybuiltup,andaworldbegan.WhenEpicurus tookupanddeveloped the theorynearly twocenturies later,

Hence heassumed that at some indeterminate point of time and space, and for noascertainable reason, an atomwas liable tomake a tiny imperceptible swervefrom its straight downward path. This deviation from the strict determinismwhichwasof theessenceof theoriginalatomictheoryhadacurioussequel inthat itwas held to allow for free-will in a universewhere otherwiseman likeeverythingelsewouldhavehadtoberegardedasentirelysubjecttoablindandinexorable destiny. Scientifically speaking it was a retrograde step, andDemocritus was thinkingmore clearly when he saw that in infinite space theconceptionofupordownhadnomeaning,andtherecouldbenoreasonfortheatomstomoveinonedirectionratherthananother.The atomists posited no separate moving cause like the attractive and

4THEREACTIONTOWARDSHUMANISM(TheSophistsandSocrates)

Thereasonsforthechangewereboundtobecomplex.Athenshadbecometheacknowledged leader of Greece in intellectual as in other matters, so thatthinkers from other parts of the Greek world, like Anaxagoras or Protagoras,tendedtobeattractedintoherorbitandtomaketheirhomesthere.ButAthensfromtheyear431wasengagedinthelongandterriblewarwhichwastoleadtoherdownfallthirtyyearslater,andsoonafteritsoutbreaksufferedallthehorrorsof the plague.

The reaction away from the investigation of physis is sometimesattributedamongotherthingstowhathasbeencalledthebankruptcyofphysicalscience,andwehavealreadyhadahintofwhatthatphrasemeans.Thebasisofphysical science in Greece, as we said at the beginning, was the search forpermanenceorstability,andforanunderlyingunity, inauniversesuperficiallymutableandunstable,andconsistingonlyofamostconfusingplurality.Totheordinarymanitmusthaveseemedthatthephysicistshadfailedconspicuously.They offered him the choice between Parmenides and the atomists. Either hecouldacceptunity in theworldat thepriceof renouncingbelief ineverythingthat seemed tohim real and admitting that all his sensationswere false; or hecould follow thosewho had given up all idea of a one behind themany andproduced a world of nothing but infinite plurality; and not even they wouldallowthenameofrealitytothesecondaryqualitieswhichmadeupmostoftheworldofhisexperience, theworld thatcouldbeseenandheardandsmeltandtasted.Thereactiontowardshumanismisassociatedwiththeriseofanewclass,the

philosophicalattitude,namelyacommonscepticism,amistrustofthepossibilityof absolute knowledge. This was a natural result of the impasse to which, itseemed, natural philosophyhad come.Knowledge depends on two things: thepossession of faculties capable of bringing us into touchwith reality, and theexistence of a stable reality to be known. As instruments of knowledge, thesenseshadnowbeenseverely treated,andsofarnothinghadbeenput in theirplace;andfaithintheunityandstabilityoftheUniversehadbeen,underminedwithout,asyet, theemergenceof theideathat theremightbeapermanentandknowablerealityoutsideandbeyondthephysicalworld.Thelifebloodofphilosophyiscontroversy.Onceitsfirstbeginningsarepast,

Itwas this scepticismwhichSocrates and his successorsmade it their life-work to combat. In the physicalfieldDemocritushadsaid that thesensationsofsweetandbitter,hotandcold,wereonlyconventionalterms.Theydidnotcorrespondtoanythingreal.Forthisreasonwhatseemedsweettomemightseembittertoyou,ortomyselfifIwereunwell,andthesamewatermightseemwarmtooneofmyhandsandcoldtothe

There can be in nature noabsolute principles governing the relations between man and man. It is all aquestionofhowyoulookatit.ThescepticalstandpointoftheSophistsmaybeillustratedbyquotationsfrom

the two best-known and most influential of their number, Gorgias andProtagoras.Thefavouritetitleforanaturalphilosophertogivetohisworkhadbeen ‘On Nature (physis) or the Existent’. In deliberate parody of the manyworks with this title, Gorgias wrote a book to which he gave the name ‘OnNature, or theNonexistent’, and in it he set out toprove three things: (a) thatnothingexists;(b)thatifanythingdidexist,wecouldnotknowit;(c)thatifwecouldknowanything,wecouldnotcommunicateittoourneighbour.Protagorasexpressedhisviewsonreligionthus:‘Concerningthegods,Ihave

The test by truth or falsehood isabandoned,andreplacedbythepragmatictest.The irreverent scepticism of the Sophists affected the hitherto unchallenged

Page 56: The Greek Philosophers: from Thales to Aristotle

sanction of law,whichwas based on a belief in its divine origin. The earliestmakers of constitutions, like Lycurgus the legendary founder of Sparta, werebelieved to have been inspired byApollo, and itwas still customary for law-givers to apply tohisoracle atDelphi andobtain, ifnot its advice, at least itssanction for theirownplans.This religious foundation for lawwasnowbeingundermined not only by the atheistical trend of natural philosophy,which theSophiststookupwithsuchzest,butalsobyexternalcircumstancessuchastheincreasing contact of theGreekswith foreign countries and the great body ofcontemporary law-making connected with the foundation of colonies. TheSophistswere the childrenof their age.The first taught them the fundamentaldifferenceswhichmightexistbetweenthelawsandcustomsofpeopleslivingindifferentclimes.Asfor thesecond, itwasdifficult tobelievethatconstitutionscame from heaven when one’s own friends (or still worse, one’s politicalenemies)wereonthecommissionwhichdrewthemup.Protagorashimselfwason the commission sent out in 443 B.C. to draft a constitution for the newAtheniancolonyofThuriiinSouthItaly.Itisnotsurprisingthathebecamethefirstpromulgatorofthattheoryoftheoriginoflawwhichwenowknowasthesocialcontract.Hesaidthatfortheirownprotectionfromwildcreaturesandforthe advancement of their standard of living men had at an early stage beenobliged to band themselves together into communities. Hitherto they had hadneithermoralstandardsnorlaws,butlifeinsocietieswasfoundtobeimpossibleifthestandardsofthejungleprevailed,andso,byslowandpainfuldegrees,theylearned the necessity of laws and conventions whereby the stronger pledgethemselvesnottoattackandrobtheweaksimplybecausetheyarethestronger.1Giventhisinitialpremise,thatlawsandmoralcodeswerenotdivineinorigin

butman-madeandimperfect,itwaspossibletodrawwidelydifferingpracticalconclusions.Protagorashimselfsaidthattheyhadcomeintobeingbecausetheywere necessary. He championed the social contract therefore and urgedsubmission to the laws. Other more radical Sophists repudiated it, andmaintained the natural right of the stronger to have his way. Differentconclusionsmightbedrawn,butthepremisewasthesameforall.Allaliketooktheir standon the complete absenceof absolutevalues and standards,whetherbasedon theological considerations or not.All human actionwas regardedbythe Sophists as based on experience alone and dictated by nothing butexpediency.Rightandwrong,wisdom, justiceandgoodness,werenothingbutnames,eventhoughitmightbearguedthatitwassometimesprudenttoactasiftheyweremore.Into this world of thought came SOCRATES. This is the outlook which

seemed tohimatonce intellectuallymistakenandmorallyharmful,andwhich

Page 57: The Greek Philosophers: from Thales to Aristotle

hemadeithislife-worktocombat.1Socrates is probably best known for the famous dictum which is usually

translated‘Virtueisknowledge’,andtofindoutwhatthismeansmakesasgoodanapproachasanytothecentreofhisteaching.Itisbestunderstoodhistorically,thatis,byrelatingittotheproblemswhichpreviousandcontemporarythought,andthecircumstancesofhistime,hadforcedonhisattention,andwhichhewasdoinghisbesttosolve.Weknownowthattheword‘Virtue’attachesfalseassociationstotheGreek

arete,whichmeantprimarilyefficiencyataparticular task.Wehavealsoseenthat the opponents against whom Socrates’s teaching was aimed claimed twothings:(a)thattheythemselvescouldteachorimpartarete,(b)thatknowledge,at least knowledgewhich could be shared,was a chimera.Therewasno suchthing.Byequatingaretewith knowledge, therefore,Socrates’s statement takesontheaspectofadeliberatechallenge,whichwecanonlyrecapturebythinkingourselvesbacktothetimesinwhichhelived.One of the things about Socrates which irritated the sensible, practical

Athenian was that he would insist on turning the talk to such humble andapparently irrelevant people as shoemakers and carpenters, when what theywantedtolearnaboutwaswhatconstitutedpoliticalabilityorwhethertherewassuchathingasmoralobligation.Ifyouwanttobeagoodshoemaker,hesaid,thefirstthingnecessaryistoknowwhatashoeisandwhatitismeantfor.Itisnousetryingtodecideonthebestsortoftoolsandmaterialtouseandthebestmethodsofusing themunlessyouhave first formed inyourmind a clear anddetailedideaofwhatitisyouaresettingouttoproduceandwhatfunctionitwillhavetoperform.TousetheGreekword,theareteofashoemakerdependedfirstand foremost on the possession of this knowledge.

In no such case did the word have anynecessaryconnexionwiththemoralaspectoftheiractivitiesasourword‘virtue’wouldsuggest.Itmeantthat inthemwhichmadethemgoodat theirparticularjob, and by taking first the humble examples of the useful crafts, it was notdifficult forSocrates to show that in eachcase the acquisitionof this capacitydepended on knowledge and that the first andmost necessary knowledgewasknowledgeineachcaseoftheendinview–whatthemanwassettingouttodo.Givenaproperunderstandingoftheend,theunderstandingofthemeanstobeadopted could follow, but not otherwise. In every instance, therefore, aretedepended first on having a definite job to do, and secondly on a thorough

Page 58: The Greek Philosophers: from Thales to Aristotle

knowledge of what the job was and what it aimed at effecting. If then (heproceeded) there is any legitimate sense in which we can talk about areteunqualified, as theSophistswere professing to teach it – that is, efficiency inliving for anyman as such – it follows that theremust be an end or functionwhichallalike,ashumanbeings,havetoperform.Thefirsttasktherefore,ifweare to acquire this universal humanvirtue, is to discoverwhat the function ofmanis.NowIwouldnotsay that fromthe recordsofSocrates’s teachingwhichwe

have in thewritingsofhispupils (forhehimselfwrotenothing,believing thatthe only thing of value was the living interchange of ideas by question andanswer between two people in personal contact) we find the answer to thisprimaryquestionoftheuniversalendoraimofhumanlife.Itsabsencefromhisteachingwas,Ishouldsay,onereasonwhichmadethemorepositivePlatofeelithis duty not only to reproduce his master’s teaching but to carry it a stagefurther.It is inkeepingwithSocrates’scharacter that theanswershouldnotbethere.Hewasaccustomedtosaythathedidnothimselfknowanything,andthattheonlywayinwhichhewaswiserthanothermenwasthathewasconsciousofhisownignorance,whiletheywerenot.TheessenceoftheSocraticmethodistoconvincetheinterlocutorthatwhereashethoughtheknewsomething,infacthedoesnot.Theconvictionofignoranceisanecessaryfirststeptotheacquisitionof knowledge, for no one is going to seek knowledge on any subject if he isunder the delusion that he already possesses it.

They held thatknowledge was impossible; he demonstrated to everybody that they knewnothing. In fact the difference was profound; for the action of Socrates wasbasedonapassionatebeliefthatknowledgewaspossible,butthatthedebrisofhalf-thought-out andmisleading ideaswhich filledmostmen’smindsmust becleared awaybefore the search for it couldbegin.Whathe set beforemen, instrong opposition to sophistic scepticism, was ‘an ideal of knowledgeunattained’.1Oncetheyhadperceivedthewaytothegoal,hewasreadytoseekit with them, and all philosophy was summed up for him in this idea of the‘commonsearch’.Neitherhiscompanion,norhehimselfknewthetruthyet,butifonlytheothercouldbepersuadedthatthiswasso,theymightsetouttogetherwithgoodhopeoffindingit.TrueSocraticismrepresentsfirstandforemostan

stoodoutforhimasparticularlymischievous.Men’stalkwasinterlardedwithagreat variety of general terms, especially terms intended to be descriptive ofethical notions – justice, temperance, courage and so forth. I started, saysSocrates, in my innocence, by supposing that they knew what these wordsmeant,sincetheyusedthemsofreely,andIsetoutfullofhopethattheywouldtellme,whodidnotknow.Whenhequestioned them,however,he found thatnoneof themcouldgivehimaproper explanation.Perhaps in the light of theSophists’ teaching it ought to be supposed that these terms had indeed nomeaning; but if so,menought tobe stopped fromusing them.

5PLATO(i)TheDoctrineofIdeas

We shall probably understand Plato’s philosophy best if we regard him asworkinginthefirstplaceundertheinfluenceoftworelatedmotives.HewishedfirstofalltotakeupSocrates’staskatthepointwhereSocrateshadhadtoleaveit, to consolidate his master’s teaching and defend it against inevitablequestioning. But in this he was not acting solely from motives of personalaffectionorrespect.Itfittedinwithhissecondmotive,whichwastodefend,andtorenderworthdefending,theideaofthecity-stateasanindependentpolitical,economic, and social unit. For it was by accepting and developing Socrates’schallenge to the Sophists that Plato thought this wider aim could be mostsuccessfullyaccomplished.The doom of the free city-state was sealed by the conquests of Philip and

Alexander.ItwasthesewhichassuredthatthatcompactunitofclassicalGreeklife should be swamped by the growth of huge kingdoms on a semi-Orientalmodel. But they did no more than complete in drastic fashion a process ofdeclinewhichhadbeengoingonforsometime.Thecauseswere,ofcourse,inpart political. There were the disruptive effects of inter-state warfare, and thedisastrous effect onAthens –where the city state organization of society hadachieved its finest flower – of defeat and the moral collapse and internaltyrannies which followed defeat. Feeding on these discontents, the prevailingcurrentsofphilosophicalthought–withwhichweareatthemomentconcerned–hadplayedtheirpartinunderminingthetraditions,theacceptedconventionsifyou like, onwhich the smooth continuance of life in the little city-state to solargeanextentdepended.Toappreciate the situation,wemust realizehowcompletely identifiedwere

Religion and patriotism were thesamething.ItisasifthereligionofBritainweretheworshipofBritannia.TheAcropolisofAthenswasAthena’sown rock, andcrownedbyher temple.Herfestival was the most important in the Athenian calendar. We may remindourselves also of something already mentioned, that the sanction of law wasrooted in the traditionalbelief in itsdivineorigin.Lawshadbeengiven to thefirst law-makers, as the tablets to Moses in Jewish belief, by the god of thepeople,ortobemorespecific,byApollo,actingasthemouthpieceorprophetoftheFatherofallthegods,Zeus.Suchathingaspersonalandindividualreligionwas unknown to the great majority of citizens. The sects which attempted tointroduce it never achieved much influence so long as the city-state heldtogether,andinsofarastheyhadanysuccess,weredefinitelysubversiveoftheestablishedorder.Itfollowsthattoquestiontheestablishedreligionwastoquestionthebasisof

thewholeestablishedorderofsociety,andthatnodefenceofthecity-statecouldbe adequate if it remained onwhatwe should regard as the political level.Areasoneddefenceofitslawsandinstitutionsmustprovidethemwithanabsoluteor transcendent validity which could hardly be divorced from a theisticconceptionofthegovernmentoftheUniverse.ItmightindeedbeimpossibletoreinstatetheoldHomericpantheoninallitsglory.Theseall-too-humanfigureshadhad theirday, andevenapart from theattacksof atheisticphilosophersorSophists could not indefinitely retain the allegiance of an intelligent andincreasingly enlightened community. But if gods in the old anthropomorphicformweredoomedinanycase,somethingmustbeputintheirplacetorestoretheelementoforderandpermanencewhichinthelatefifthcenturywasrapidlyvanishingalikefromthesphereofconductandfromthatofnature.In the field of thought, the attack on the traditional bases of established

institutions was threefold: from natural philosophy, from the sophisticmovement, and from mysticism. With the last named we shall not be muchconcernedhere,butmaynoteinpassingtheexistenceof independentreligiousteachers,ofwhomthosewhoused thewritingsattributed toOrpheuswere themost important, whose doctrine was subversive in that it taught that a man’sreligionmightconcernhisownindividualsoulandnothisdutytotheState.Thedangerofnaturalphilosophy lay in its lesson that thegods couldnotpossiblyexistintheforminwhichthecityhadinheritedthemfromHomer;andthatoftheSophists intheirsuggestionthat thelawsof thecityhadafterallnodivine

sanction:theyhadbeenmadebymanandmightaseasilybeunmade.These various currents of thought had already been having their effect for

some time when Plato wrote. Since he was among other things a practicalpoliticalthinker,whohadrenouncedanactivepoliticalcareeronlytodevotehislife to the consideration of political ideas, he was committed to one of twocourses.Eitherhemustrecognize(asheissometimesnowadaysblamedfornotrecognizing)thatthecity-statewithallitsinstitutionsandconvictionsbelongedtothepast,joinwiththedisruptiveforces,andoutofthedifferentelementsthathadbroughtaboutitsdownfallbuildupanewsocietyandanewreligiontotakeitsplace;orelsehemustuseallhispowerstoupholdthecity-state,refutingitsopponentswheretheyseemedwrong,andusingthemonlytoaddstrengthtoitsframeworkwheretheywererightandrepresentedanelementthelackofwhichwas aweakness in the existing order. In any case the two sides, political andreligious (or metaphysical), must go together. No real reform of thefundamentals of political thought could take place without a correspondingreform ofmen’s ideas about thewhole nature of reality.All thiswas clear toPlato,andhethrewthewholeofhisforcesonthesideofHellenismandthecity-state.Thewritingof theRepublic in theprimeofhis life,andhisreturntothesamesubjectat theendofitwiththeLaws,showthathewastruetothesameideal throughout, the idealofa reformedsocietybasedon thepurificationandstrengthening,notontheabolition,ofthecity-state.AmongtherulingclassesinPlato’sRepublic the individual is tobesubordinated to thecommonwealwithwhat appears to our eyes an excessive relentlessness. The taking away fromthese, themost valuable citizens of the state, of property and family life, thecommunalsupervisionoftheirchildren,thedistributionofdutiesandprivilegesaccording to analmost inexorable systemof class-distinctions– all this seemsshocking to our eyes. One of the listeners in the dialogue itself is moved toremarkthatthosewhointheneworderaretobethemastersofthestatedonotseem destined for a particularly happy life, since theywill have no houses orlandsorotherpossessionsbut liveas if theywereagarrisonofmercenaries–without even drawing a mercenary’s pay, as Socrates points out to make hisfriend’scriticismevenstrongerthanitwas.Theonlyreplygivenis:Ouraiminfounding thecitywasnot togiveespecialhappiness tooneclass,butasfaraspossibletothecityasawhole.’Themeasuresproposedwerethelogicalconclusionofthecity-state,andPlato

The consequence of this doctrine appeared to be that therecould be no knowledge of this world, since one cannot be said to haveknowledgeof somethingwhich isdifferentat thismoment fromwhat itwasamomentago.Knowledgedemandsastableobject tobeknown.Parmenidesonthe other hand had said that there is such a stable reality, which can bediscoveredonlythroughtheactivityofthemindworkingaltogetherapartfromthe senses.

If there is not some common ground ofmeaning when the same epithet is applied to different objects, thencommunication between man and man must be given up as impossible. Thiscommongroundwe call the idea or conception of goodness or equality.Mostpeoplewould fighthard for their right to continueusing theword ‘good’, andwould claim that it has a meaning of its own. Yet its use involves a realintellectualproblem,andinfactsomephilosophersto-day,whenPlatonicbeliefsare rather out of fashion among our schoolmen, are very much inclined toquestion the claim that the use of general terms is legitimate at all. Certainlysome of us who use them might be hard put to it to say what there was incommonbetweenthebodilyskillrequiredtobowlastraightballorhitadifficultone,andtheflavourofawine.Platowouldmaintainthattheyhadsomethingincommon,andthatthiscouldonlybeaccountedforbytheassumptionthatbothalikepartakeintheIdeaoftheGood.Youarerighttospeakasyoudooftheideaofgoodnessorequality,hewouldsay,butitisjustthesethingswhichyoucallmerely ideas, or concepts in themind, which wemust believe to be absoluteentitieswithanexistenceindependentofourmindsandoutofreachoftimeorchange.Otherwiseknowledgeisanidledreamanditsobjectfantasy.Withthisfaithonemayreasonablygoontoseekforadefinitionofthegood,andonewillthenunderstand twodifferentphenomenaofourworld– the cricketer and thewine, say – in their common character as good, by referring them to it as acommonstandard.We must suppose then an ideal world containing eternal and perfect

Since this is an attitude which has something in it of an almostreligiousfaith,evenofmysticalexperience,andcannotbeentirelyexplainedbyrational argument (though Plato would have maintained very strongly thatrational argument proves that we cannot do without it), Plato has recourse tometaphor toexplain therelationbetween the twoworlds.Aristotle fastenedonthis as a weakness, but it could hardly have been otherwise.

no quarrel, yet they would not agree with Plato in attributing to that class-concept an individual existenceof its own, independent of themembers of itsclass, or the constant and unvarying character which is the consequence ofindependent existence. If to Plato all this seemed to follow, then that wasdoubtlessduetocertainphilosophicalpredilectionsofhisown.Inthefirstplace,he shared with Socrates those two fundamental characteristics, a faith in thepossibility of knowledge and a conviction of the need for absolute moralstandards.And though itmay seem to us that it is possible to share this faithwithoutmakingtheassumptionthatthereareeternalentitiesoutsidetheworldoftimeandspace,itwasmuchmoredifficulttodothisattheparticularpointinthehistoryofphilosophywhenPlatowasdoinghis thinking.WeneedonlyreflectforamomentontheprevioushistoryofGreekphilosophywhichwehavenowfollowed – the ceaseless flux which the Heracliteans attributed to the naturalworld, the insistence of Parmenides that what is real should be eternal andunmoved.

They represent strong probabilities but no more.Nevertheless, imposing edifices of scientific theory have been built on theassumption of their invariable truth. Without the faith that the same laws of

Yet it is no more than faith, unless we give a transcendental andabsolutevalidity to them.We treat themas if theyhad this absolutecharacter,whileatthesametimedenyingthattheyhaveit.Anevenbetterexampleof theobjectifying,at least inordinaryspeech,ofa

6PLATO(ii)EthicalandtheologicalanswerstotheSophists

I should like now to develop Plato’s ethical doctrine further by describinganotherofitsfundamentalconceptions.Thedoctrineoftranscendentformswasnottheonlyanswer,asitwasnotinitselfacompleteanswer,totheanti-socialideasofsomeoftheSophists.AnotherlineofattackwhichPlatodevelopedwastoraisethequestionofthebestandhealthiestconditionofthesoul,andtoinsistthat this depended on the presence of order, forwhich he uses both thewordkosmos,withwhichwearefamiliar,andtaxis,awordmorenarrowlyconfinedtothe meaning of ‘orderly arrangement’. I want therefore to inquire what wasmeantby thisconceptionoforder in thesoul,andhowitmaybesaid tohaverebutted the sophistic arguments. It will be necessary first to discuss somepreliminary matter, and in particular – as I gave warning we should findourselvesdoing– to turnback foramoment to the thoughtofSocrates.But Imention the theme at the outset, so that itmay be kept inmind as the end towhichourtrainofthoughtisleading.In early societies, where communities are small and cultural conditions

simple,noconflict isobservedbetweenmoraldutyand self-interest.AsRitterremarks1:‘Hewhoinhisrelationshiptohisfellowmenandthegodsobservestheexistingcustomsispraised,respectedandconsideredgood;whereashewhobreaks them is despised, disciplined and considered bad.

to ‘law’, and the conception of ‘nature’s justice’ as not only different fromman’s, but something greater and finer. This is upheld in Plato’sGorgias byCallicles, who although he professes contempt for the Sophists represents thesophisticviewatitsmostextreme.HeexemplifiesitbytheexploitsofXerxes.Acorollaryofthisistheequationofthegoodwiththepleasant,wherebythe

ideaofdutyisexplicitlydenied.Thestrongman,whoisnature’sjustman,hasno duty except to act according to his own pleasure. Hedonism as aphilosophicaldoctrineisborn.Both Socrates and Plato were concerned to deny this equation of the good

with the pleasant. It must be true to say, for example, that the orator who inaddressing the demos seeks only to please themmay do them a great deal ofharm;andthattheoratorwhoisaimingattheirgoodmayfinditnecessarytosaysomeextremelyunpalatablethings.Butifpleasureis thegood, it is impossibletomakestatements like these.Howthendid theysetaboutshowingthat thosewhoidentifiedthepleasantandthegoodwerewrong?Socrates countered them in the first place by his insistence on the need of

We need another word to equate with ‘the good’ and explain it. Socrateshimselfsuggestsawordwhichmeans theuseful,orbeneficial.Thegoodmustbesomethingwhichalwaysbenefits,neverharms.Ifwedefineitthus,thenactswhich in themselves give pleasure can be referred to the question of ultimatebenefitastoahigherstandard,whilestillmaintainingtheattitudeofpureself-interest.In all probability the intensely practical Socrates got no further than this

In the Protagoras he is actually represented as defending, in anargumentwithSophists, theequivalenceofpleasureandgood,butheuses theword‘pleasant’inthislargersense.Hepointsoutthatthepleasureonwhichwebaseourcalculationsmustbeinthefutureaswellasinthepresent,andbeforehehasdone,hehassucceededinincludingeverythingunderthisheadwhichinother dialogues he describes as beneficial, andwhich is deliberately excludedfrom pleasure when in theGorgias he is arguing against the equivalence ofpleasantandgood.InfactSocrates’sideaofpleasureastheequivalentofgoodincludes all that inmodern speech comes under the heading of ‘values’,with,indeed,moreemphasisonspiritualvaluesthanonanyothers.Thepossibilityofdistinguishing between good and bad pleasures, while nominally adopting adoctrine of consistent hedonism, is achieved by admitting the principle ofcalculation.Noneofthechampionsofpleasurewerepreparedtodenythis,yetwith it, the so-called hedonismmay be refined almost indefinitely into a highmoralcode.1Itwas thus that Socrates in his inquiries reduced all the virtues to one and

describedthatoneaswisdomorknowledge–theknowledgeofgoodandevil.Havingenumerated thecommonlyacceptedvirtues in theMeno, he continues:‘Nowtakethosewhichdonotseemtobeknowledge,andconsiderwhethertheyarenotharmfulsometimesaswellasbeneficial.Courageforinstance.Supposecourageisnotwisdombutakindofrecklessness.Isitnottruethatwhenamanisconfidentwithoutreasonhecomes toharm,butwhenwithreason, togood?Allthesequalitieswhenpractisedanddisciplinedinassociationwithreasonarebeneficial,butwithoutreasonhurtful.Inshort,allundertakingsofthespirit,andallthatitendures,leadtohappinesswhenguidedbywisdom,butwhenbyfolly,to the opposite. If therefore virtue is an attribute of the spirit and one whichcannotfailtobebeneficial,itmustbewisdom.Forallspiritualqualitiesinandbythemselvesareneitherbeneficialnorhurtful,butbecomesobythepresencewiththemofwisdomorfolly.’JudgedbythepragmaticalstandardwhichSocratesisadvocating,itisnotthe

He takes his given piece ofmaterial,andallthetimethatheiscarvingandputtingittogether,whathehastokeep his mind fixed on is the work of the weaver. He does not fashion itaccordingtohisownwhims,butinsubordinationtoapredeterminedendwhichcontrols the structure it is to have.

It failsbecause,owing to its individualism, it impliesthat if itwere possible for aman to deceive everyone – even the gods – intothinking that he had lived righteously when he had not, there would be noargumentbywhichjusticecouldbecommendedtohim.Inotherwords,itisnotadefenceof justice for itsownsake.ThisdefencePlato isanxious toprovide,consideringonly thenatureof justice itself,andshowing it tobesuch that thejust man must be immediately happy because he is just and virtuous. Thequestionofhisreputation,andofwhatrewardsorpunishmentsawaithiminthefuture,mustbesetasideasirrelevant.He begins by repeating the point that everything has its proper ergon.

It is this arete which wemean by justice.Hence the justman is living in the fullest andbestway, and cannot fail to behappyaswellasgood.AtthispointtheSophistThrasymachusironicallyexpresseshimselfsatisfied.

Socrates,however,resumestheargumentbyremarkingthattheyhavenotafterallgotfaryet,fortheyhavenotinfactdecidedwhatthis‘beststate’ofthesoulis,towhichthenamesofjusticeandvirtuearetobeapplied.Itisofcoursethisfurthersearchwhichleadsdirectlytothedescriptionoftheidealpolity,foritisnextagreed that itmaybeeasier tosee justice firstwrit large in thecity,afterwhichtheycanreturntolookforitinthespiritoftheindividualwhentheyhaveamorepreciseideaofitsnature.Justiceofcourse,orinGreekdikaiosyne,isinordinaryspeechprimarilyamatteroftherelationsbetweenmanandman.Hencethereasonablenessofseekingitfirstinacommunity.Todeterminewhataretherightandjustrelationsbetweenmenlivinginthesamecommunitywillputoneinabetterpositiontodeterminewhatismeantbyajustman:forbythatphraseonemeansaboveallamanofsuchacharacterthathewillnaturallytendtokeeptherightrelationsbetweenhimselfandhisneighbour.Thatiswhatismeantbyjusticeintheindividual.In the building up of the polity which follows, it emerges that it is like

As time goes on it will be largely an aristocracy of birth, for Plato thinks itoverwhelminglylikelythatthechildrenofeachclasswillbothbyheredityandenvironmentinclinetoresembletheirparentsanddevelopintosuitablemembersofthesameclass.Headdshoweverthatmachinerymustbeprovidedwherebyifanexceptionallygiftedchildshouldappearamongthelowestclass,oroneofthehighest show himself unworthy to be trained as a ruler, transfers between theclassesmaybeeffected.To avoid misunderstanding, certain points in this organization should be

emphasized.ThelowestclassinPlato’sstateissometimesspokenofbymodernwritersas the ‘masses’, andcertainly inpointofnumbers itwillbeby far thelargest. But it differs remarkably from the proletariat of which the Marxistspeaks,beinginfacttheonlyclasspermittedtoholdprivatewealth.Oneoftheworst evils of political life, in Plato’s opinion, was the material greed ofpoliticians.Itwasanevilcertainlynotabsentfromthedebaseddemocracyofhisday. His aim therefore was the complete divorce of political from economicpower.Bythismeanshehopedtogetaclassofstatesmenwhosesoleambitionwas to govern well.

Iwish to summarize, though very briefly,whatPlatosaysaboutthis,partlybecauseIhavechosentomaketheconflictwiththeSophists the thread of my discourse, and partly because it will assume freshimportance when we pass on to Aristotle. His theology started where Plato’sstopped,anditisimportanttobeinapositiontocomparethetwo.The theological defence of law is in the tenth book of the Laws. First the

ordesign,natureandartare thesame thing.Art is theproductof intelligence,and intelligence is the highest manifestation of nature, prior not only inimportance but in time to chance, in fact the first cause of all. Clearly ametaphysicwhich, if itcanbeproved,willhavefar-reachingeffectsonethicaltheoriesaswell.The sophistic doctrines, Plato argues, have inverted the proper order of

causation by their supposition that the first causewas a randommovement ofmatterwithoutlife,outofwhichlifearoseasasecondarymanifestation.Infactlifemust have been there first, and is the primary cause of themovements ofmatter. The proof starts from an analysis ofmotion, in thewide sense of theGreekwordkinesis,which includeschangeof everykind. It is finallybroughtunder two main heads, spontaneous and communicated.

Yet it did no more thanclarify and develop a tendency that had been in Greek philosophy from the

hadalreadyamassedhimself.This peaceful existence was shattered when in the summer of 323 the

incredible news ofAlexander’s death reachedAthens.TheAthenian assemblyimmediately decided on the liberation of Greek cities from Macedoniangarrisons. In thewaveofanti-Macedonian feelingwhichensued,achargewastrumpedupagainstAristotle,theoldchargeofimpietywhichhadbeenlevelledat Anaxagoras and Socrates. With Socrates in mind Aristotle is said to haveremarked, as he retired to voluntary banishment atChalkis inEuboea, that hewished to ‘prevent the Athenians from committing a second sin againstphilosophy’.AtChalkishehadlivedonlyayearwhenhediedin322,attheageofsixty-two.ThehallmarkofAristotleasaphilosopher isarobustcommonsense,which

refused tobelieve that thisworldwasanythingbut fully real.Philosophy,as itappearedtohim,wasanattempttoexplainthenaturalworld,andifitcouldnotdo so, or could explain it only by the introduction of a mysterious,transcendentalpattern-world,devoidofthecharacteristicallynaturalpropertyofmotion,thenitmustbeconsideredtohavefailed.HiscommentonthePlatonicIdeasistypical:‘Buttocallthempatterns,orspeakoftheotherthingsassharinginthem,istotalkinemptywordsandpoeticmetaphors.’Inevitablythereforethedominantnoteofhisphilosophyisconflict.Forthis,

aswehave seen, is themanwhowas thepupil and friendofPlato for twentyyears from the age of seventeen. As a young man he accepted the whole ofPlato’s two-world philosophy – the doctrine of Ideas, the immortality andtransmigration of the soul, and the view of earthly knowledge as a gradualrecollectionofknowledgefromanotherworld.Ifhelaterfeltcompelled,asanindependent thinker, to give up the mystical doctrines of the Ideas and thekinship of the soul with things beyond, there were parts of the legacy whichneverlefthim.FundamentallyheremainedonthesideofPlatoandSocrates.AsCornfordput it: ‘Forall this reaction towards thestandpointofcommonsenseandempiricalfact,AristotlecouldneverceasetobeaPlatonist.Histhought,noless thanPlato’s, isgovernedby the ideaofaspiration, inheritedbyhismasterfrom Socrates – the idea that the true cause or explanation of things is to besought,notinthebeginning,butintheend.’1In other words, the question that both can and must be answered by

philosophyisthequestion‘Why?’Toanswerthequestion‘How?’isnotenough.To speakmore strictly,wemay say that thepermanent legacyofPlatonism toAristotlewastwofold,thoughitstwosideswereintimatelyconnected.Whathetookoverandretainedwas:

Hecouldnotgiveuphissenseofthesupremeimportanceofform,withwhich,aswehavenowseen,itwasnaturalfortheGreekstoincludefunction.Toknowthe matter out of which a thing had come to be was only a secondaryconsideration, since the originalmatterwas something shared by itwith otherthingswhich had developed differently,whereas to understand itmeant to laybarethecharacteristicswhichdistinguisheditfromotherthings.Thedefinitionthenmustdescribetheformintowhichithadgrown.Inthat,accordingtoPlatoandAristotle,layitsessence.Thisquestionoflookingfortheessenceofthingsinthe‘out-of-which’orthe‘into-which’introducesustoafundamentalcleavageofoutlookwhichexistsinthepresentworldasintheancient,amonglaymenaswellasphilosophers.Knowingaswedothatmanhasevolvedfromlowertypesof life, it isnatural for some tosay thathe is ‘afterallnothingbut’anape,orevenapieceofprotoplasm,whichhashappenedtotakeacertaindirection.Toothershisessenceliesinthequalitieswhichnowdistinguishhimfromthelowerformsoflifetowhichhisancestorsbelonged.Theyseeitnotinwhathehasleftbehind,butinhiscapabilities,bothpresentandevenfuture.Whathecannowdoistheimportantthing–hisfunction,dependentonhisform.Theultimatereasonfor thechoice isprobablynot rational, and it isnotoriously impossible for theonesidetoconvincetheotherbyargument.Here then was a man with a conviction as strong as Plato’s both that

knowledge was possible, and that it must be knowledge of form and not ofmatter. Yet from these premises Plato, as we know, deduced that the onlypossible explanation lay in the assumption of a world of transcendent andabsoluteformspartiallyandtransientlyrealizedintheworldofnature.FromthisAristotle’s common sense revolted, because the relationship between the twoworlds, the causality of the Ideas, remained unaccounted for. Above all theyofferednohelpinexplainingwhathadbeenthecruxofearlyGreekphilosophyandseemedtoAristotletheonethingaboveallthatneededexplanation;thatis,the phenomena of motion and change. He therefore renounced them, but thedifficulty which they were designed to obviate may be presumed to haveremained.Howbringwithinthecompassofphilosophicknowledgeaworldofunstablephenomena,alwayschanging,comingintoexistenceandpassingawayagain,neverthesamefortwoinstantstogether?Whereisthatstabilitywhich,aswesawatthebeginning,thehumanminddemands?Aristotle’sanswerliesintworelatedconceptsfundamentaltohisphilosophy:

In introducing thisconception,onemust say first

of all that teleology as Plato andAristotle understood it demanded the actualexistenceofthe telosorend, that is,ofaperfectionunderwhoseinfluencetheactivityofthenaturalworldtakesplace.Thisisnotanecessarypresuppositionof the idea of ordered progress. Ordered progress is a perfectly possibleconception without the assumption that the perfection, or goal, to which it istendingalreadyexistsanywhere.This is indeedtheideafavouredbyamodernevolutionarybiologistlikeJulianHuxley:butthePlatonistdoesnotthinkinthatway.InAristotle’swords:‘Wherethereisabettertheremustbeabest’,oraswemightputit,comparisonsaremeaninglessunlessthereisanabsolutestandardtowhichtheymaybereferred.Youcannotwellspeakofprogress,orindeedknowwhetherthingsaregoingforwardsorbackwards,unlessyourscaleofvaluesisotherthanpurelyrelative;anditmustberelativeunlessthereexistssomewhereaperfectionbywhich theycanbe judged,accordingas they fall shortof itbyless or more. So at least Aristotle thought. This perfection is provided inAristotle’s world by its god, who is the only pure form existing apart frommatter.Heisnottheformofanythingintheworld,sowearenotbroughtbacktotheseparatespecificformsofPlato,whichtoAristotleseemedakindofuselessreplicaofperceptiblethings.To thenatureof this supremebeingwemust return later, continuing for the

presentintheworldofsense.Inthisworldeverynewlyconceivedcreaturemusthaveaparent,whichisintwosensesitscause:firstashavingperformedtheactofbegetting,andsecondlyasbeinganexampleofthespecificformtowhichthenewcreaturewillgrowup.InAristotle’sterms, theparent isnecessarybothasefficientandasformal-finalcause.Itisthe‘nature’oftheinfantanimalorplantto strive to realize its own specific form, as exemplified in the parent, whichmust preexist. Had the world been created in time, the hen, in Aristotle’s

Page 93: The Greek Philosophers: from Thales to Aristotle

philosophy, would have come before the egg. He held, however, that it hasexisted eternally, and its existence as a whole is ensured by the eternal andabsoluteperfectionofthepureform,God.Itisofcourseonlyinaloose,becauserelativesensethattheindividualparentrepresentsperfection.Theentomologistspeaks of the ‘perfect insect’ to contrast it with the larva, but it displays noabsolute perfection. If to produce an individual creature requires a previouslyextantperfectioninthepartialandrelativesphereofthespecies,theexistenceofthewholeworldcollectivelydemandstheexistenceofanabsoluteperfection.Byrealizing as adequately as it can its own specific form, every creaturemaybesaidtobe imitating, in itsownlimitedway, theeternalperfectionofGod.Theinward urge to do this is what is meant by the ‘nature’ (physis) of a naturalobject. So impressed was Aristotle with the necessity to explain motion – anecessitywhich the previous history ofGreek thought had, in awaywhich IhopeIhavemadeclear,renderedparamount–thathemadeitthedefinitionofnatural objects that they ‘containwithin themselves a principle ofmotion andrest’.Some,aswehaveseen,hadbeensoovercomebythedifficultyofaccounting

for motion that they had been led to the desperate expedient of denying itsexistence.Platohimself(thoughtherearepassagesinhislaterdialogueswhichsuggestthathewasuneasyaboutit)hadbeenforcedbythefactofitsmotiontodeclarethat theworldwasonlyquasi-real,andthatrealitymustbesoughtinatranscendent sphere divorced from physical movement and change. By thewholehearted acceptance of motion then, to which his more scientific (andspecifically biological) temperament led him, Aristotle was laid under theobligation of answering those who, like Parmenides, had declared it to beimpossible.ThedilemmaofParmenideswasasmuchasanything theresultofthe immaturity of logic and language in his day, and the way to escape hadalreadybeenpointedoutbyPlato.Aristotleparaphrasedthedilemmaasfollows:Thereisnosuchthingasbecoming,sinceneitherwillthatwhichisbecome(foritalreadyis),norcananythingcometobeoutofwhatisnot.Platohadshownthat thisdilemmadepended for its effectivenesson inability to realize that theverb‘tobe’isusedwithtwoquitedifferentmeanings,(a)toexistand(b)tohaveacertainpredicate(tobeaman,tobehot,etc.).Withthisbehindhim,Aristotleintroduced as his solution the twofold concept of being as either potential oractual,adistinctionsoconstantlyusedto-daythatitisdifficulttorememberhowmuchthoughtwasneededtopavethewayforit.The old antithesis between ‘what is’ and ‘what is not’ does not, he said,

representthetrueposition.Certainlywherenothingatallexists,therenevercanbeanything.NoGreekwoulddenythedictumexnihilonihil,andthatwasone

Page 94: The Greek Philosophers: from Thales to Aristotle

of the reasonswhy he held theworld to be eternal. That, however, is not thesituationwehavetodealwith.Anembryo‘isnot’aman.Thestatementdoesnotimplynonexistence,butratherthepositivefactthathereisapieceofmatterofsuch a nature that it is possible for it to become aman. In otherwords, it ispotentiallyaman.Givenhisanalysisofconcreteobjectsintosubstrateandform,hecouldsaythatitconsistedofasubstratepossessedatthemomentofwhathecalled the ‘privation’ of the form ofman. This again is not a purely negativestatement, but implies thepotentialityof realizing the form.All nature is seenwith theeyesofa teleologist,andtheconceptionoffunctionishere tooin theforefront.Thefunctionofaneye,forexample,istosee.InAristotelianterms,ithasnotfullyrealizeditsformandactualityunlessitisseeing.Ifthenaneyeisblind, it is characterized by the ‘privation’ of sight. The statement cannotproperlybeappliedtotheleafofaplant,thoughthatdoesnotseeanymorethantheblindeyeofanew-bornkitten,because it isnot itsnature tosee. Ifon theotherhandaplant isgrown in thedark so that its leavesarewhitish, theyarerightly said tobe characterizedby theprivationofgreenness,which it is theirnature to attain. Form is essence, or the true nature of a thing, and the fullpossessionofformisequivalenttotheproperperformanceoffunction.Thetwoconceptionsheredescribed(a)immanentform,and(b)thenotionof

potential and actual being – are thus closely interrelated. The view of naturalcreaturesasprogressing fromthepotential to theactualbyvirtueof theirowndynamicnaturecannotbeseparatedinthemindfromtheanalysisofthingstakenas they stand which reveals the necessity for an indeterminate substratumcapableofbeinginformedtodifferentdegreesbyqualitieswhichinthemselvesare untransformable. The one might be compared to an instantaneous X-rayphotograph; the other is an explanation of the process. Since, however, toAristotle’smind thephenomenaprimarilydemandingexplanationwerechangeandmotion,it isthedynamicviewofnaturegivenbytheconceptsofdynamisandenergeiawhichdominates thesystemand isofmostuse to its inventor informulatingtheoriesineverybranchofknowledge.WecannowapproachthequestionoftheAristotelianGodandhisrelationto

theworld.Platoinhisoldagehad,aswesaw,definedGodassoulandsoulasself-mover.Aristotle started from thatpoint,butcouldnot rest there, since theconception did not satisfy his conscientious rationalism. His god was not aninitialpostulate,butthefinalstepinachainofreasoningwhichledhimtotheconclusion that the concept of anything self-movedwas an impossibility.Thisargument from motion may seem remote from anything which we areaccustomed to regard as theology, but is nevertheless essential to anunderstandingofthepeculiarnatureoftheAristoteliandeity.

sentient, in fact divine, and so therefore are the spheres and heavenly bodiesmadeofit,orofanadmixtureofitwithfire.To return to the supreme god, we have shown that he must be unmoved,

eternal, and perfect. It follows that hemust be incorporeal.Moreover, if he isfree from motion, and none of him is potential, he must be pure actuality(energeiainGreek).WemustrememberthatinthephilosophyofAristotle,withits emphasis on function, the acquisition of form, as a static condition orstructure,isnotyetthehigheststageofbeingforanything.Thisconsistsnotinthepossessionoffacultiesbutintheexerciseofthem.Thatisenergeia.Whereaskinesisisthearduousprocessof‘growingup’,oracquiringactuality,energeiaistheunimpededflowofactivitymadepossibleonceactualityhasbeenacquired.Thus the conception of God as unmoved – or unchanging – and pure form,unsatisfactory as it remains, for several reasons, to the religious mind, is notquitesocoldandstaticasitappearsatfirstsight.Aspureactualityheis,thoughexemptfromkinesis,eternallyactivewithanactivitywhichbringsnofatiguebutisforeverenjoyable.Hisessentialqualityislife.Ofwhat thendoeshis activityconsist?He is engaged ineternal thought.

He is pure mind, which cancontemplate in a single instant, anddoes so eternally, thewhole realmof truebeing.It is a splendid thought, but unfortunately we have not finished with the

philosophicconscience.‘Thewholerealmoftruebeing’–yes,butofwhatdoesthisrealmconsist?TheconclusionisthattheonlypossibleobjectoftheeternalthoughtofGod ishimself, theone full andperfectbeing.There isnowaybywhich he could include in his thought the creatures of the physical world,without abandoning the initial postulate on which all his nature depends.

AndAristotle’s biological studies hadtaughthimthat there isnohardandfast linebetween thefacultiesofdifferentordersofnature,asthereisnohardandfastlinebetweenthegenera.Althoughnot an evolutionist, he notes as a result of his observationsofmarine life thatthereisobviouslynodetectablelineofcleavagebetweenplantsandanimals;of

somecreatures it ishard to say towhichclass theybelong.Suchobservationsmust havemade it easier for him to postulate a single internal force, or élan,pervadingallnature,sentientandnon-sentientalike.WemaydisliketheconclusionstowhichAristotlewasled,butwecanhardly

help admiring the consistency of his thought. The theological climax of hissystem is reached by applying the same fundamental principles as hold goodthroughout. In natural generation, aswe saw, themost important aspects of aparent’s causation are the formal and final. He is necessary above all asproviding an example of the fully formed creature towhich the offspringwillconform. Since the offspring is created in time, hemust act as efficient causetoo;theremustbeaninitialactofbegetting.Butafterthat,heneedtheoreticallytake no further notice of the young, whose internal dynamis will ensure theircontinueddevelopmentprovidedtheperfectmembersofthespeciesonlyexisttofurnish the model. The relation of God to the world is the same, with thenecessarydifference that since theworldwasnever createdbut is coevalwithtime itself, no initial act of creation in time is called for, and the lastconsiderationisremovedwhichcouldcauseGodtodisplayevenamomentaryinterest in theworld.He is none the less necessary to its existence, in awaywhich is nowclear.To recallCornford’s dictum,wemay say that inAristotle‘thephilosophyofaspiration’reachesitsfinalculmination.

8ARISTOTLE(ii)Humanbeings

IhavegivensomeaccountinoutlineofAristotle’sviewsontheworkingsoftheUniverse as a whole. To conclude this brief survey, the most fitting subjectseems to be his views onman, his nature and position in the world, and hisproperoccupationor function.What I shall have to say falls roughly into twohalves,psychologyandethics.I use psychology of course in the Greek sense of the study of the psyche,

whichistheelementoflifeinlivingcreaturesfromplantsupwards,andincludesas a minimum the faculties of nutrition and reproduction, and also, in thosecreatures which possess them, the desires and emotions, the senses, and thereason.Aswitheveryothersubject,Aristotlestartsfromadiscussionoftheopinions

ofhispredecessors.Fromthisdiscussion twomainpointsofcriticismemerge,illustrating in particular how his common sense reacted against the semi-religious beliefs of the Pythagoreans and Plato, though at the same time histreatment of them shows that he was equally anxious to avoid the purelymaterialistexplanationsofsensationandthoughtwhichhadbeenpropoundedbyEmpedoclesandtheAtomists.Thetwochiefpointswhichhepicksoutforcriticismarethese:(a)Failureto

grasp with sufficient clearness that the psyche must be conceived as a unity,althoughpossessingperhapsdifferentfaculties(dynameis).Platohadspokenofdifferent ‘parts’ of the soul. In Aristotle’s work this word ‘parts’ is usuallyreplacedbytheworddynameis–facultiesorpowers.(b) Failure to grasp its relation to the body. The others speak of it as

something separate,which perhaps can be detached from the body and live aseparatelifebyitself.Infactnotonlyissoul itselfaunity,butsois thewholelivingcreature,soulandbodytogether.Hencetheoriesofthetransmigrationofasoulintodifferentbodiesareabsurd.Thetwoarelogicallydistinguishable–soul

Nevertheless one momentous consequence would seem to follow from thedoctrineofsoulastheformofthebodyifinterpretedinallitsstrictness.Itisadeath-blow to any kind of personal immortality. Living creatures like othernaturalobjectsformeachoneaunity,andtheircomponentsofformandmatterare not separable except in thought. In his ownwords: ‘The questionwhethersoulandbodyareoneisnomorelegitimatethanthequestionwhetherthewaxandtheimpressionofthesealuponitareone,oringeneralwhetherthematterof a thing is onewith the thing ofwhich it is thematter.’On the question ofhuman survival he says little, and the natural inference would be that, unlikePlato,hewasnotgreatly interested in it.Hiscuriosityabout thepresentworldwas too consuming to leave room for a desire to speculate about another.Neverthelesshedoesseemtohaveleftaloophole,holdingthatnous,thehighestmanifestation of the reasoning faculty,was of a different order from the othervitalprinciples,andmightinfactbeaseparatesubstanceinitsownrightwhichcouldsurvivethedissolutionofthebody.Heseveraltimesmentionsthequestionandshelvesit,asinthispassagefromtheDeanima:‘Concerningthemind,thepowerofactivethought,wehaveasyetnoevidence.Itappearstobeadifferentgenus of soul, and to be alone capable of separate existence, as the eternal isindependent of the perishable.But all the other parts of soul, as is clear fromwhathasbeen said, are incapableof separate existence, in spiteofwhat somehaveclaimed.Theyare,ofcourse,distinguishableindefinition.’InapurelyscientificpassageofhistreatiseontheGenerationofAnimals,he

actually concludes that reason, of all the manifestations of life, ‘alone entersfrom outside and is divine’, because all the others can be shown to beinseparablefromsomeactivityof thebody.Wemayalso take intoaccounthisexhortationsattheendoftheEthicstothelifeofpurethoughtasbeingnotonlythe exerciseof ourownhighest faculty, but also the cultivationof that part inwhichweresembleGod.Inthepossessionofnousheundoubtedlybelievedthatmanhassomethingwhichisnotsharedbyotherformsoflife,andwhichhedoessharewith the eternal unmoved cause of theUniverse.

This theory gives to his views on sensation twoadvantagesoverthoseofhispredecessorswhichbecomeapparentinthedetailsofhiswork.(a)We know that one effect of his general doctrinewas to draw the bonds

It is just the difference between the two events which constitutessensation. His own explanation in general terms is that the sense-organ iscapable,becausethisisacharacteristicofalllivingmatter(matter-plus-psyche),ofreceivingtheformofsensibleobjectswithouttheirmatter.Thereismaterialaffection: the flesh becomes warmwhenwe perceive warmth, the eye (so hebelieved) coloured when we perceive a colour.

The distinction could hardly be more clearlyexpressed.Aristotle therefore calls sensation a judgment, ranking it nearer to reason

That is the culminating stage of development, forwhich the attainment of the form or state was the preparation.

The seeming paradox that it is byperformingvirtuous acts thatwe acquire virtue (for surely, onemight say, theperformanceofvirtuousacts is theresultofbeingvirtuous,not itscause:howcanweactvirtuouslyifwehavenotyetvirtueinoursouls?)–tothisparadoxAristotle finds a reply in another of his fundamental concepts, that ofpotentiality.Isvirtuenaturalorcontrarytonature?Neithersideisquiteright.Inhis ownwords: ‘Neither by nature, then, nor contrary to nature do the virtuesariseinus;butbynatureweareadaptedtoreceivethem,andaremadeperfectbyhabit.’Wearepotentiallygood,with thedynamis ofvirtue inuswhichwemaydevelopintotheeidosbyformingrighthabits.Buteverythingwhichisonlysomething potentially is capable of developing in the opposite direction.

Do we do best to retire intophilosophic isolation, or to plunge into practical matters and learn fromexperience(whichhasnowbecomeouronlyguide)howtodealwithourfellow-men?

Page 108: The Greek Philosophers: from Thales to Aristotle

The answer is determined, like everything else for this most consistent ofphilosophers,byreferencetothefundamentalsofhistheoryofnature,andwilltherefore be in termswithwhichwe are familiar. For the answer is this, thatman, like every other separately existing natural creature, is concrete, acompoundofmatterandform,andhisergonissimilarlycomplex.Itishisdutytoliveaccordingtothehighestthatisinhim,andthisisthepowerofthought.Butheisnotagodandcannotdothatwithoutintermission.Hence,aswesaw,the need for the lower virtues aswell. This dual conception of human natureleadsAristotlesometimestoanapparent,orverbal,inconsistency.Forinstance,whenman is being contrastedwith the lower orders of nature, it is of coursenous which is the distinguishing characteristic; and so the proper, becausepeculiarfunctionofmanisseentolieintheexerciseofnous.Whenontheotherhandmanisbeingcontrastedwithhigherbeings,towitwithGod,thenitishisimperfectionsandhisassociationswithmatterwhichnaturallycometothefore.AndsoevenAristotle’sfinalandalmostlyricalaccountofthetruehappinessforman,inthelastbookofthetreatisedoesnotescapegivingtheimpressionofatleastsuperficialcontradiction.ThistrueandhighesthappinessliesforAristotleintheoreticalscienceandphilosophy,theunfetteredexerciseoftheintellectforits own sake.

Ifreason isdivine, then, incomparisonwithman, the lifeaccording to itwillbedivineincomparisonwithhumanlife.’At the same time he follows this up with the exhortation to disregard the

But I thinkwe shouldmisunderstand himmore than we need if we failed to recognize this distinction between thecompositenatureofmanandthecompositenatureofthelowerordersofbeing.Thedifferenceliesinthis,thatthebestinhim–thatwhichisinthefullestsensehisowntruenature–isidenticalwiththenatureofthatwhichisabovehim,withthenatureofGod.WehaveseenhowtheonlyadequatedescriptionthatAristotlecould find of the eternal and blessed life which the highest divinity must besupposedtoleadwasthatitconsistedinuninterruptedthought.‘Fortheactivityofmindislife.’TodenywhatIhavesaidabouthumannaturewouldbetodenyboththeletter

But the moral virtues (and here I quote Aristotle’s own words) aresecondary. It is thecreedof theunrepentant intellectualist. ‘Theactivityof themindislife.’Aristotle’s philosophy represents the final flowering ofGreek thought in its

natural setting, the city-state. Hewas the teacher of Alexander, themanwho
