Rational animal is a classical definition of man.[1] Though it is often attributed to first appearing as a definition in Aristotle's Metaphysics, Aristotle does not define it here. In the Nicomachean Ethics I.13, Aristotle states that the human being has a rational principle.

The definition of man as a rational animal was common in scholastical philosophy.[2] Catholic Encyclopedia states that this definition means that "in the system of classification and definition shown in the Arbor Porphyriana, man is a substance, corporeal, living, sentient, and rational".[2]

[edit] Influence and legacy

[edit] Descartes

In Meditation II of Meditations on First Philosophy, Descartes arrives at his famous "I am, I exist" claim. He then goes on to wonder "What am I?" He considers and rejects, "rational animal":

Shall I say 'a rational animal'? No; for then I should have to inquire what an animal is, what rationality is, and in this one question would lead me down the slope to other harder ones.[3]

[edit] Later influences

Neo-kantian philosopher Ernst Cassirer, in his work An Essay on Man (1944), altered Aristotle definition to label man as a symbolic animal. This definition has been influential in the field of philosophical anthropology, where it has been reprised by Gilbert Durand.
