In the Symposium Socrates recounts the teaching of Diotima, who leads him from the claim that lovers seek their “other half” to the statement that men love “the good” and the “everlasting possession” of it. The dialogue is Plato’s principal work on Eros, and later discussions of love take their terms from it. It stands under “Desire” as the account of love as a longing for what one does not yet have.
Read in context‘Yes,’ she added, ‘and you hear people say that lovers are seeking for their other half; but I say that they are seeking neither for the half of themselves, nor for the whole, unless the half or the whole be also a good.
And they will cut off their own hands and feet and cast them away, if they are evil; for they love not what is their own, unless perchance there be some one who calls what belongs to him the good, and what belongs to another the evil. For there is nothing which men love but the good. Is there anything?’ ‘Certainly, I should say, that there is nothing.’
‘Then,’ she said, ‘the simple truth is, that men love the good.’ ‘Yes,’ I said. ‘To which must be added that they love the possession of the good?’ ‘Yes, that must be added.’ ‘And not only the possession, but the everlasting possession of the good?’ ‘That must be added too.’ ‘Then love,’ she said, ‘may be described generally as the love of the everlasting possession of the good?’ ‘That is most true.’
