“Diotima taught me all this doctrine in the discourse we had together concerning Love; and, in addition, she inquired, ‘What do you think, Socrates, is the cause of this love and desire? Do you not perceive how all animals, both those of the earth and of the air, are affected when they desire the propagation of their species, affected even to weakness and disease by the impulse of their love; first, longing to be mixed with each other, and then seeking nourishment for their offspring, so that the feeblest are ready to contend with the strongest in obedience to this law, and to die for the sake of their young, or to waste away with hunger, and do or suffer anything so that they may not want nourishment. It might be said that human beings do these things through reason, but can you explain why other animals are thus affected through love?’--I confessed that I did not know.--‘Do you imagine yourself,’ said she, ‘to be skilful in the science of Love, if you are ignorant of these things?’--‘As I said before, O Diotima, I come to you, well knowing how much I am in need of a teacher. But explain to me, I entreat you, the cause of these things, and of the other things relating to Love.’--‘If,’ said Diotima, ‘you believe that Love is of the same nature as we have mutually agreed upon, wonder not that such are its effects. For the mortal nature seeks, so far as it is able, to become deathless and eternal. But it can only accomplish this desire by generation, which for ever leaves another new in place of the old. For, although each human being be severally said to live, and be the same from youth to old age, yet, that which is called the same, never contains within itself the same things, but always is becoming new by the loss and change of that which it possessed before; both the hair and the flesh, and the bones, and the entire body.
