I said, ‘O thou stranger woman, thou sayest well; but, assuming Love to be such as you say, what is the use of him to men?’ ‘That, Socrates,’ she replied, ‘I will attempt to unfold: of his nature and birth I have already spoken; and you acknowledge that love is of the beautiful. But some one will say: Of the beautiful in what, Socrates and Diotima?—or rather let me put the question more clearly, and ask: When a man loves the beautiful, what does he desire?’ I answered her ‘That the beautiful may be his.’ ‘Still,’ she said, ‘the answer suggests a further question: What is given by the possession of beauty?’ ‘To what you have asked,’ I replied, ‘I have no answer ready.’ ‘Then,’ she said, ‘let me put the word “good” in the place of the beautiful, and repeat the question once more: If he who loves loves the good, what is it then that he loves?’ ‘The possession of the good,’ I said. ‘And what does he gain who possesses the good?’ ‘Happiness,’ I replied; ‘there is less difficulty in answering that question.’ ‘Yes,’ she said, ‘the happy are made happy by the acquisition of good things. Nor is there any need to ask why a man desires happiness; the answer is already final.’ ‘You are right.’ I said. ‘And is this wish and this desire common to all? and do all men always desire their own good, or only some men?—what say you?’ ‘All men,’ I replied; ‘the desire is common to all.’ ‘Why, then,’ she rejoined, ‘are not all men, Socrates, said to love, but only some of them? whereas you say that all men are always loving the same things.’ ‘I myself wonder,’ I said, ‘why this is.’ ‘There is nothing to wonder at,’ she replied; ‘the reason is that one part of love is separated off and receives the name of the whole, but the other parts have other names.’ ‘Give an illustration,’ I said. She answered me as follows: ‘There is poetry, which, as you know, is complex and manifold. All creation or passage of non-being into being is poetry or making, and the processes of all art are creative; and the masters of arts are all poets or makers.’ ‘Very true.’ ‘Still,’ she said, ‘you know that they are not called poets, but have other names; only that portion of the art which is separated off from the rest, and is concerned with music and metre, is termed poetry, and they who possess poetry in this sense of the word are called poets.’ ‘Very true,’ I said. ‘And the same holds of love. For you may say generally that all desire of good and happiness is only the great and subtle power of love; but they who are drawn towards him by any other path, whether the path of money-making or gymnastics or philosophy, are not called lovers—the name of the whole is appropriated to those whose affection takes one form only—they alone are said to love, or to be lovers.’ ‘I dare say,’ I replied, ‘that you are right.’

‘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.’
‘Then if this be the nature of love, can you tell me further,’ she said, ‘what is the manner of the pursuit? what are they doing who show all this eagerness and heat which is called love? and what is the object which they have in view? Answer me.’ ‘Nay, Diotima,’ I replied, ‘if I had known, I should not have wondered at your wisdom, neither should I have come to learn from you about this very matter.’ ‘Well,’ she said, ‘I will teach you:—The object which they have in view is birth in beauty, whether of body or soul.’ ‘I do not understand you,’ I said; ‘the oracle requires an explanation.’ ‘I will make my meaning clearer,’ she replied. ‘I mean to say, that all men are bringing to the birth in their bodies and in their souls. There is a certain age at which human nature is desirous of procreation—procreation which must be in beauty and not in deformity; and this procreation is the union of man and woman, and is a divine thing; for conception and generation are an immortal principle in the mortal creature, and in the inharmonious they can never be. But the deformed is always inharmonious with the divine, and the beautiful harmonious. Beauty, then, is the destiny or goddess of parturition who presides at birth, and therefore, when approaching beauty, the conceiving power is propitious, and diffusive, and benign, and begets and bears fruit: at the sight of ugliness she frowns and contracts and has a sense of pain, and turns away, and shrivels up, and not without a pang refrains from conception. And this is the reason why, when the hour of conception arrives, and the teeming nature is full, there is such a flutter and ecstasy about beauty whose approach is the alleviation of the pain of travail. For love, Socrates, is not, as you imagine, the love of the beautiful only.’ ‘What then?’ ‘The love of generation and of birth in beauty.’ ‘Yes,’ I said. ‘Yes, indeed,’ she replied. ‘But why of generation?’ ‘Because to the mortal creature, generation is a sort of eternity and immortality,’ she replied; ‘and if, as has been already admitted, love is of the everlasting possession of the good, all men will necessarily desire immortality together with good: Wherefore love is of immortality.’

All this she taught me at various times when she spoke of love. And I remember her once saying to me, ‘What is the cause, Socrates, of love, and the attendant desire? See you not how all animals, birds, as well as beasts, in their desire of procreation, are in agony when they take the infection of love, which begins with the desire of union; whereto is added the care of offspring, on whose behalf the weakest are ready to battle against the strongest even to the uttermost, and to die for them, and will let themselves be tormented with hunger or suffer anything in order to maintain their young. Man may be supposed to act thus from reason; but why should animals have these passionate feelings? Can you tell me why?’ Again I replied that I did not know. She said to me: ‘And do you expect ever to become a master in the art of love, if you do not know this?’ ‘But I have told you already, Diotima, that my ignorance is the reason why I come to you; for I am conscious that I want a teacher; tell me then the cause of this and of the other mysteries of love.’ ‘Marvel not,’ she said, ‘if you believe that love is of the immortal, as we have several times acknowledged; for here again, and on the same principle too, the mortal nature is seeking as far as is possible to be everlasting and immortal: and this is only to be attained by generation, because generation always leaves behind a new existence in the place of the old. Nay even in the life of the same individual there is succession and not absolute unity: a man is called the same, and yet in the short interval which elapses between youth and age, and in which every animal is said to have life and identity, he is undergoing a perpetual process of loss and reparation—hair, flesh, bones, blood, and the whole body are always changing. Which is true not only of the body, but also of the soul, whose habits, tempers, opinions, desires, pleasures, pains, fears, never remain the same in any one of us, but are always coming and going; and equally true of knowledge, and what is still more surprising to us mortals, not only do the sciences in general spring up and decay, so that in respect of them we are never the same; but each of them individually experiences a like change. For what is implied in the word “recollection,” but the departure of knowledge, which is ever being forgotten, and is renewed and preserved by recollection, and appears to be the same although in reality new, according to that law of succession by which all mortal things are preserved, not absolutely the same, but by substitution, the old worn-out mortality leaving another new and similar existence behind—unlike the divine, which is always the same and not another? And in this way, Socrates, the mortal body, or mortal anything, partakes of immortality; but the immortal in another way. Marvel not then at the love which all men have of their offspring; for that universal love and interest is for the sake of immortality.’

I was astonished at her words, and said: ‘Is this really true, O thou wise Diotima?’ And she answered with all the authority of an accomplished sophist: ‘Of that, Socrates, you may be assured;—think only of the ambition of men, and you will wonder at the senselessness of their ways, unless you consider how they are stirred by the love of an immortality of fame. They are ready to run all risks greater far than they would have run for their children, and to spend money and undergo any sort of toil, and even to die, for the sake of leaving behind them a name which shall be eternal. Do you imagine that Alcestis would have died to save Admetus, or Achilles to avenge Patroclus, or your own Codrus in order to preserve the kingdom for his sons, if they had not imagined that the memory of their virtues, which still survives among us, would be immortal? Nay,’ she said, ‘I am persuaded that all men do all things, and the better they are the more they do them, in hope of the glorious fame of immortal virtue; for they desire the immortal.
