The natural function of the wing is to soar upwards and carry that which is heavy up to the place where dwells the race of gods. More than any other thing that pertains to the body it partakes of the nature of the divine.
PlatoBut he who has been earnest in the love of knowledge and of true wisdom, and has exercised his intellect more than any other part of him, must have thoughts immortal and divine. If he attain truth, and in so far as human nature is capable of sharing in immortality, he must altogether be immortal.
Plato
