« It is the possession of perception [aisthesis] that leads us for the first time to speak of living things as animals [zōia]: for even those beings which possess no power of local movement but do possess the power of perception we call animals [zōia] and not merely living beings [ou zen monon]. »
(Aristotle, De Anima, II, 413b 1-4) « For Aristotle, plants are merely living beings; zōnta; but they are not zōia, because they have no share in perception, which is a form of cognition. [...]. The fact that Aristotle normally uses the term zōia to refer to animals, to the exclusion of plants, is ultimately due to his conviction that animals are a distinct class of living beings. »
(Falcon, Aristotle and the science of nature, 6)
Plants as merely living beings

Aristotle's Definition of Animals
Perception and appetite are equiprimordial powers: “Where there are feelings of pleasure and pain (lupe te kai hedone), there must be desire (orexis)”
(DA, 434 a 1; 413 b 23)

The Movement of Animals
Involuntary movements (to akousion) eg. heart's beating
Non-voluntary movements (ouk hekousion) eg. sleep/waking, respiration, digestion
Voluntary movements (to hekousion) [or action (praxis)*] eg. actions such as walking, hunting and other similar behaviors

“It is insofar as an animal is capable of appetite that it is capable of self-movement and it is not capable of appetite without possessing phantasia”
(De Anima, 433b27)
“It is always the desirable [to orekton] that moves the animal, but it can be either the real or the apparent good [to phainomenon agathon]”
(De Anima 433a 27-28)

CONCLUSION : Action (praxis) or voluntary movement (= the animal goes to look for the drink)
Aristotle's Practical Syllogism
Voluntary movements (or actions) follow the formal structure of the syllogism :
The action follows naturally the conjonction of the premisses as does the conclusion of a logical syllogism without any decision or deliberation. Animal behaviors are genuine actions (praxis), even if they are not rational or deliberated actions (praxis meta logou).

Animals endowed with memory are “more intelligent [phronimotera] and apt at learning”
(Metaphysics, 980b26)
In the History of Animals, he often describes animals as phronimos, intelligent (eg. HA, 588a20). “Some animals are classified as prudent (phronimos), those which, in all matters relating to their own lives, have a clear ability to predict.”
(Nichomachean Ethics, 1141a25-28)

Voice or phone
Sounds produced by animals are signs (semeion) of their pleasure and pain and they use their voice
(phone) to communicate these affections to each other.
(Aristotle, Politics, 1253a8-14)

Voice or phone
Sounds produced by animals are signs (semeion) of their pleasure and pain and they use their voice
(phone) to communicate these affections to each other.
(Aristotle, Politics, 1253a8-14)
Birds use their voice to communicate among themselves (pro hermeneian alloesis) and to
teach something to another.
(The Parts of Animals, 660a17-b2)

Meaning & Communication (The Crane)
“Many indications of high intelligence [phronesis] are given by cranes. [...] They have a leader in their flight [...]. When they settle down, they go to sleep with their heads under their wing [...] while their leader, with his head uncovered, keeps a sharp look out, and when he sees anything of importance signals it with a cry [sêmainei boon].”
(History of Animals, 614b21-26)

« Animals have the faculty of hearing so that something can be communicated to them and have a tongue so that it may communicate with its fellows. »
(De Anima, 435b24-25)
Even deprived of language (logos), animals can communicate with
one another through meaningful sounds (sêmantikos psophos) and
signify (sêmainein) something to another.

Conclusion : Living or Living Well ?
« Touch is indispensable. Necessarily, if an animal is to survive, its body must have tactual sensation. (…) Without touch it is impossible for an animal to be. »
« All the other senses are necessary to animals, as we have said, not for their being, but for their well-being (eu zēn). »
End of the De Anima
“eu zēn”can also be translated by
happiness

Animals are defined through two basic capacities :
to feel (aisthesis) and to move by oneself (kinesis)
through some form of discrimination (krinein)
and representation/imagination (phantasia)

Perception (aisthesis) Memory (mneme) Experience (emperia) Art (techne) Science (episteme) Wisdom (sophia)
Modalities of Understanding in Aristotle's Metaphysics:
Aisthesis is the most primitive form of aletheuien, “because it discloses the world, though indeed not in speech and assertion (logos)” (Heidegger GA 22, 186), it is a form of uncovering that lets something be “known” in a certain sense.
