Symposium

But the offspring of the heavenly Aphrodite is derived from a mother in whose birth the female has no part,—she is from the male only; this is that love which is of youths, and the goddess being older, there is nothing of wantonness in her. Those who are inspired by this love turn to the male, and delight in him who is the more valiant and intelligent nature; any one may recognise the pure enthusiasts in the very character of their attachments. For they love not boys, but intelligent beings whose reason is beginning to be developed, much about the time at which their beards begin to grow.

The Love who is the offspring of the common Aphrodite is essentially common, and has no discrimination, being such as the meaner sort of men feel, and is apt to be of women as well as of youths, and is of the body rather than of the soul

he elder one, having no mother, who is called the heavenly Aphrodite—she is the daughter of Uranus; the younger, who is the daughter of Zeus and Dione—her we call common; and the Love who is her fellow-worker is rightly named common, as the other love is called heavenly.
