Meno. Платон
of the manner in which the true teacher may draw out the mind of youth; this was in contrast to the quibbling follies of the Sophists. In the Meno the subject is more developed; the foundations of the enquiry are laid deeper, and the nature of knowledge is more distinctly explained. There is a progression by antagonism of two opposite aspects of philosophy. But at the moment when we approach nearest, the truth doubles upon us and passes out of our reach. We seem to find that the ideal of knowledge is irreconcilable with experience. In human life there is indeed the profession of knowledge, but right opinion is our actual guide. There is another sort of progress from the general notions of Socrates, who asked simply, 'what is friendship?' 'what is temperance?' 'what is courage?' as in the Lysis, Charmides, Laches, to the transcendentalism of Plato, who, in the second stage of his philosophy, sought to find the nature of knowledge in a prior and future state of existence.
The difficulty in framing general notions which has appeared in this and in all the previous Dialogues recurs in the Gorgias and Theaetetus as well as in the Republic. In the Gorgias too the statesmen reappear, but in stronger opposition to the philosopher. They are no longer allowed to have a divine insight, but, though acknowledged to have been clever men and good speakers, are denounced as 'blind leaders of the blind.' The doctrine of the immortality of the soul is also carried further, being made the foundation not only of a theory of knowledge, but of a doctrine of rewards and punishments. In the Republic the relation of knowledge to virtue is described in a manner more consistent with modern distinctions. The existence of the virtues without the possession of knowledge in the higher or philosophical sense is admitted to be possible. Right opinion is again introduced in the Theaetetus as an account of knowledge, but is rejected on the ground that it is irrational (as here, because it is not bound by the tie of the cause), and also because the conception of false opinion is given up as hopeless. The doctrines of Plato are necessarily different at different times of his life, as new distinctions are realized, or new stages of thought attained by him. We are not therefore justified, in order to take away the appearance of inconsistency, in attributing to him hidden meanings or remote allusions.
There are no external criteria by which we can determine the date of the Meno. There is no reason to suppose that any of the Dialogues of Plato were written before the death of Socrates; the Meno, which appears to be one of the earliest of them, is proved to have been of a later date by the allusion of Anytus.
We cannot argue that Plato was more likely to have written, as he has done, of Meno before than after his miserable death; for we have already seen, in the examples of Charmides and Critias, that the characters in Plato are very far from resembling the same characters in history. The repulsive picture which is given of him in the Anabasis of Xenophon, where he also appears as the friend of Aristippus 'and a fair youth having lovers,' has no other trait of likeness to the Meno of Plato.
The place of the Meno in the series is doubtfully indicated by internal evidence. The main character of the Dialogue is Socrates; but to the 'general definitions' of Socrates is added the Platonic doctrine of reminiscence. The problems of virtue and knowledge have been discussed in the Lysis, Laches, Charmides, and Protagoras; the puzzle about knowing and learning has already appeared in the Euthydemus. The doctrines of immortality and pre-existence are carried further in the Phaedrus and Phaedo; the distinction between opinion and knowledge is more fully developed in the Theaetetus. The lessons of Prodicus, whom he facetiously calls his master, are still running in the mind of Socrates. Unlike the later Platonic Dialogues, the Meno arrives at no conclusion. Hence we are led to place the Dialogue at some point of time later than the Protagoras, and earlier than the Phaedrus and Gorgias. The place which is assigned to it in this work is due mainly to the desire to bring together in a single volume all the Dialogues which contain allusions to the trial and death of Socrates.
ON THE IDEAS OF PLATO
Plato's doctrine of ideas has attained an imaginary clearness and definiteness which is not to be found in his own writings. The popular account of them is partly derived from one or two passages in his Dialogues interpreted without regard to their poetical environment. It is due also to the misunderstanding of him by the Aristotelian school; and the erroneous notion has been further narrowed and has become fixed by the realism of the schoolmen. This popular view of the Platonic ideas may be summed up in some such formula as the following: 'Truth consists not in particulars, but in universals, which have a place in the mind of God, or in some far-off heaven. These were revealed to men in a former state of existence, and are recovered by reminiscence (anamnesis) or association from sensible things. The sensible things are not realities, but shadows only, in relation to the truth.' These unmeaning propositions are hardly suspected to be a caricature of a great theory of knowledge, which Plato in various ways and under many figures of speech is seeking to unfold. Poetry has been converted into dogma; and it is not remarked that the Platonic ideas are to be found only in about a third of Plato's writings and are not confined to him. The forms which they assume are numerous, and if taken literally, inconsistent with one another. At one time we are in the clouds of mythology, at another among the abstractions of mathematics or metaphysics; we pass imperceptibly from one to the other. Reason and fancy are mingled in the same passage. The ideas are sometimes described as many, coextensive with the universals of sense and also with the first principles of ethics; or again they are absorbed into the single idea of good, and subordinated to it. They are not more certain than facts, but they are equally certain (Phaedo). They are both personal and impersonal. They are abstract terms: they are also the causes of things; and they are even transformed into the demons or spirits by whose help God made the world. And the idea of good (Republic) may without violence be converted into the Supreme Being, who 'because He was good' created all things (Tim.).
It would be a mistake to try and reconcile these differing modes of thought. They are not to be regarded seriously as having a distinct meaning. They are parables, prophecies, myths, symbols, revelations, aspirations after an unknown world. They derive their origin from a deep religious and contemplative feeling, and also from an observation of curious mental phenomena. They gather up the elements of the previous philosophies, which they put together in a new form. Their great diversity shows the tentative character of early endeavours to think. They have not yet settled down into a single system. Plato uses them, though he also criticises them; he acknowledges that both he and others are always talking about them, especially about the Idea of Good; and that they are not peculiar to himself (Phaedo; Republic; Soph.). But in his later writings he seems to have laid aside the old forms of them. As he proceeds he makes for himself new modes of expression more akin to the Aristotelian logic.
Yet amid all these varieties and incongruities, there is a common meaning or spirit which pervades his writings, both those in which he treats of the ideas and those in which he is silent about them. This is the spirit of idealism, which in the history of philosophy has had many names and taken many forms, and has in a measure influenced those who seemed to be most averse to it. It has often been charged with inconsistency and fancifulness, and yet has had an elevating effect on human nature, and has exercised a wonderful charm and interest over a few spirits who have been lost in the thought of it. It has been banished again and again, but has always returned. It has attempted to leave the earth and soar heavenwards, but soon has found that only in experience could any solid foundation of knowledge be laid. It has degenerated into pantheism, but has again emerged. No other knowledge has given an equal stimulus to the mind. It is the science of sciences, which are also ideas, and under either aspect require to be defined. They can only be thought of in due proportion when conceived in relation to one another. They are the glasses through which the kingdoms of science are seen, but at a distance. All the greatest minds, except when living in an age of reaction against them, have unconsciously fallen under their power.
The account of the Platonic ideas in the Meno is the simplest and clearest, and we shall best illustrate their nature by giving this first and then comparing the manner in which they are described elsewhere, e.g. in the Phaedrus, Phaedo, Republic; to which may be added the criticism of them in the Parmenides, the personal form which is attributed to them in the Timaeus, the logical character which they assume in the Sophist and Philebus, and the allusion to them in the Laws. In the Cratylus they dawn upon him with the freshness of a newly-discovered thought.
The Meno goes back to a former state of existence, in which men did and suffered good and evil, and received the reward or punishment of
