The soul, when using the body as an instrument of perception — that is to say, when using the sense of sight and hearing, or some other sense — for the meaning of perceiving through the body is perceiving through the senses — is dragged by the body through the region of the changeable (the temporal), and wanders about and is confused. The world spins round her. She is like a drunkard when she touches change… But when, returning into herself she reflects, then she passes into the region of Eternity.

Socrates (470 – 399 B.C.E.)
