We may take first a certain number of comparatively short dialogues, which are strongly Socratic in the following respects: first, they each seek a definition of some particular virtue or quality; second, each suggests some relation between it and knowledge; third, each leaves the answer somewhat open, treating the matter suggestively rather than dogmatically. These dialogues are Charmides, which treats of Temperance (mens sana in corpore sano); Lysis, which treats of Friendship; Laches, Of Courage; Ion, Of Poetic Inspiration; Meno, Of the teachableness of Virtue; Euthyphro, Of Piety.
The last of these may be regarded as marking a transition to a second series, which are concerned with the trial and death of Socrates. The Euthyphro opens with an allusion by Socrates to his approaching trial, and in the Apology we have a Platonic version of Socrates' speech in his own defence; in Crito we have the story of his noble self-abnegation and civic obedience after his condemnation; in Phaedo we have his last conversation with his friends on the subject of Immortality, and the story of his death.
Another series of the dialogues may be formed of those, more or less satirical, in which the ideas and methods of the Sophists are criticised: Protagoras, {137} in which Socrates suggests that all virtues are essentially one; Euthydemus, in which the assumption and 'airs' of some of the Sophists are made fun of; Cratylus, Of the sophistic use of words; Gorgias, Of the True and the False, the truly Good and the truly Evil; Hippias, Of Voluntary and Involuntary Sin; Alcibiades, Of Self-Knowledge; Menexenus, a (possibly ironical) set oration after the manner of the Sophists, in praise of Athens.
The whole of this third series are characterised by humour, dramatic interest, variety of personal type among the speakers, keenness rather than depth of philosophic insight. There are many suggestions of profounder thoughts, afterwards worked out more fully; but on the whole these dialogues rather stimulate thought than satisfy it; the great poet-thinker is still playing with his tools.
A higher stage is reached in the Symposium, which deals at once humorously and profoundly with the subject of Love, human and divine, and its relations to Art and Philosophy, the whole consummated in a speech related by Socrates as having been spoken to him by Diotima, a wise woman of Mantineia. From this speech an extract as translated by Professor Jowett may be quoted here. It marks the transition point from the merely playful and critical to the relatively serious and dogmatic stage in the mind of Plato:—
{138} "Marvel not," she said, "if you believe that love is of the immortal, as we have already 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, which is still more surprising—for not only do the sciences in general come and go, 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 a 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 risks greater far than they would have run for their children, and to spend money and undergo any sort of {139} 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 is still retained 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.
"They whose bodies only are creative, betake themselves to women and beget children—this is the character of their love; their offspring, as they hope, will preserve their memory and give them the blessedness and immortality which they desire in the future. But creative souls—for there certainly are men who are more creative in their souls than in their bodies—conceive that which is proper for the soul to conceive or retain. And what are these conceptions?—wisdom and virtue in general. And such creators are poets and all artists who are deserving of the name inventor. But the greatest and fairest sort of wisdom by far is that which is concerned with the ordering of states and families, and which is called temperance and justice. And he who in youth has the seed of these implanted in him and is himself inspired, when he comes to maturity desires to beget and generate. He wanders about seeking beauty that he may beget offspring—for in deformity he will beget nothing—and naturally embraces the beautiful rather than the deformed body; above all when he finds a fair and noble and well-nurtured soul, he embraces the two in one person, and to such an one he is full of speech about virtue and the nature and pursuits of a good man; and he tries to educate him; and at the touch of the beautiful which is ever present to his memory, even when absent, he brings forth that which he had conceived long before, and in company with him tends that which he brings forth; and they are married by a far nearer tie and have a closer friendship than those who beget mortal children, for the children who are their common offspring are fairer and more immortal. Who, when he thinks of Homer and Hesiod and other great poets, {140} would not rather have their children than ordinary human ones? Who would not emulate them in the creation of children such as theirs, which have preserved their memory and given them everlasting glory? Or who would not have such children as Lycurgus left behind him to be the saviours, not only of Lacedaemon, but of Hellas, as one may say? There is Solon, too, who is the revered father of Athenian laws; and many others there are in many other places, both among Hellenes and barbarians. All of them have given to the world many noble works, and have been the parents of virtue of every kind, and many temples have been raised in their honour for the sake of their children; which were never raised in honour of any one, for the sake of his mortal children.
"These are the lesser mysteries of love, into which even you, Socrates, may enter; to the greater and more hidden ones which are the crown of these, and to which, if you pursue them in a right spirit, they will lead, I know not whether you will be able to attain. But I will do my utmost to inform you, and do you follow if you can. For he who would proceed aright in this matter should begin in youth to visit beautiful forms; and first, if he be guided by his instructor aright, to love one such form only—out of that he should create fair thoughts; and soon he will of himself perceive that the beauty of one form is akin to the beauty of another; and then if beauty of form in general is his pursuit, how foolish would he be not to recognise that the beauty in every form is one and the same! And when he perceives this he will abate his violent love of the one, which he will despise and deem a small thing, and will become a lover of all beautiful forms; in the next stage he will consider that the beauty of the mind is more honourable than the beauty of the outward form. So that if a virtuous soul have but a little comeliness, he will be content to love and tend him, and will search out and bring to the birth thoughts which may improve the young, until he is compelled to contemplate and see the beauty of institutions and laws, and to understand that the beauty of them all is of one family, and that personal beauty is a trifle; and after laws and institutions he will go on to the sciences, that he may see their beauty, being not like a servant in love with the beauty of one youth or man or {141} institution, himself a slave mean and narrow-minded, but drawing towards and contemplating the vast sea of beauty, he will create many fair and noble thoughts and notions in boundless love of wisdom; until on that shore he grows and waxes strong, and at last the vision is revealed to him of a single science, which is the science of beauty everywhere. To this I will proceed; please to give me your very best attention.
"He who has been instructed thus far in the things of love, and who has learned to see the beautiful in due order and succession, when he comes toward the end will suddenly perceive a nature of wondrous beauty (and this, Socrates, is the final cause of all our former toils)—a nature which in the first place is everlasting, not growing and decaying, or waxing and waning, in the next place not fair in one point of view and foul in another, or at one time or in one relation or at one place fair, at another time or in another relation or at another place foul, as if fair to some and foul to others, or in the likeness of a face or hands or any other part of the bodily frame, or in any form of speech or knowledge, or existing in any other being; as for example, in an animal, or in heaven, or in earth, or in any other place, but beauty only, absolute, separate, simple, and everlasting, which without diminution and without increase, or any change, is imparted to the ever-growing and perishing beauties of all other things. He who under the influence of true love rising upward from these begins to see that beauty, is not far from the end. And the true order of going or being led by another to the things of love, is to use the beauties of earth as steps along which he mounts upwards for the sake of that other beauty, going from one to two, and from two to all fair forms, and from fair forms to fair practices, and from fair practices to fair notions, until from fair notions he arrives at the notion of absolute beauty, and at last knows what the essence of beauty is. This, my dear Socrates," said the stranger of Mantineia, "is that life above all others which a man should live, in the contemplation of beauty absolute; a beauty which if you once beheld, you would see not to be after the measure of gold, and garments, and fair boys and youths, whose presence now entrances you; and you and many a one would be content to live seeing only and conversing with them without meat or drink, {142} if that were possible—you only want to be with them and to look at them. But what if man had eyes to see the true beauty—the divine beauty, I mean, pure and clear and unalloyed, not clogged with the pollutions of mortality, and all the colours and vanities of human life—thither looking, and holding converse with the true beauty divine and simple? Do you not see that in that communion only, beholding beauty with the eye of the mind, he will be enabled to bring forth, not images of beauty, but realities (for he has hold not of an image but of a reality), and bringing forth and nourishing true virtue to become the friend of God and be immortal, if mortal man may. Would that be an ignoble life?" (Jowett, Plato, vol. ii. p. 58).
