    Elemento Celestiale

    Etere / Quintessenza(Immutabile, senza peso, trasparente)

    Movimento naturale:Circolare, eterno, sempre

    uguale a s stesso

    Celestial ElementAether / Quintessence(Immutable, no weight, transparent)

    Natural motion:Circular, eternal, always

    equal to itself

    Due tipi di movimentoNaturale

    Forma immanente &

    Causa finaleViolento, Forzato

    Causa esterna, efficiente"La natura causa di movimento

    nella cosa stessa, la forza lacausa in qualcosa d'altro, o nella

    cosa in s considerata comequalcosa daltro. Tutto ilmovimento naturale o forzato.

    De Caelo 301 b

    Two kinds of motion

    NaturalImmanent form &

    Final CauseViolent, Forced

    External cause, efficientNature is a cause of movementin the thing itself, force a cause

    in something else, or in the thingitself regarded as somethingelse. All movement is either

    natural or enforced.On the Heavens 301 b

    Forza (esterna)"Perch solo quando

    qualcosa esterna quellache muove una cosa, o la

    mette al riposo contro la

    propria tendenza interna,

    che noi diciamo si accadeper forza. Altrimenti non

    diciamo che si accade con

    la forza."

    Ethica Eudemeia 2, 8

    Force (external)For it is only when

    something external moves athing, or brings it to rest

    against its own internal

    tendency, that we say this

    happens by force; otherwisewe do not say that it

    happens by force.

    Ethica Eudemeia 2, 8

    Movimento ViolentoIn tutti i casi di

    spostamento locale ci sarnulla tra il motore e il

    mosso L'agente

    spingendo o tirando deveessere a contatto diretto

    con il carico.Fisica

    Violent MotionIn all cases of local

    movement there will benothing between the mover

    and the moved The

    pushing or pulling agentmust be in direct contact

    with the load.Physics
