(c) The argument from imitation assumes a different character when the supposed imitations are associated with other passages having the impress of original genius. The strength of the argument from undesigned coincidences of style is much increased when they are found side by side with thoughts and expressions which can only have come from a great original writer. The great excellence, not only of the whole, but even of the parts of writings, is a strong proof of their genuineness – for although the great writer may fall below, the forger or imitator cannot rise much above himself. Whether we can attribute the worst parts of a work to a forger and the best to a great writer, – as for example, in the case of some of Shakespeare's plays, – depends upon the probability that they have been interpolated, or have been the joint work of two writers; and this can only be established either by express evidence or by a comparison of other writings of the same class. If the interpolation or double authorship of Greek writings in the time of Plato could be shown to be common, then a question, perhaps insoluble, would arise, not whether the whole, but whether parts of the Platonic dialogues are genuine, and, if parts only, which parts. Hebrew prophecies and Homeric poems and Laws of Manu may have grown together in early times, but there is no reason to think that any of the dialogues of Plato is the result of a similar process of accumulation. It is therefore rash to say with Oncken (Die Staatslehre des Aristoteles) that the form in which Aristotle knew the Laws of Plato must have been different from that in which they have come down to us.
It must be admitted that these principles are difficult of application. Yet a criticism may be worth making which rests only on probabilities or impressions. Great disputes will arise about the merits of different passages, about what is truly characteristic and original or trivial and borrowed. Many have thought the Laws to be one of the greatest of Platonic writings, while in the judgment of Mr. Grote they hardly rise above the level of the forged epistles. The manner in which a writer would or would not have written at a particular time of life must be acknowledged to be a matter of conjecture. But enough has been said to show that similarities of a certain kind, whether criticism is able to detect them or not, may be such as must be attributed to an original writer, and not to a mere imitator.
(d) Applying these principles to the case of the Laws, we have now to point out that they contain the class of refined or unconscious similarities which are indicative of genuineness. The parallelisms are like the repetitions of favourite thoughts into which every one is apt to fall unawares in conversation or in writing. They are found in a work which contains many beautiful and remarkable passages. We may therefore begin by claiming this presumption in their favour. Such undesigned coincidences, as we may venture to call them, are the following. The conception of justice as the union of temperance, wisdom, courage (Laws; Republic): the latent idea of dialectic implied in the notion of dividing laws after the kinds of virtue (Laws); the approval of the method of looking at one idea gathered from many things, 'than which a truer was never discovered by any man' (compare Republic): or again the description of the Laws as parents (Laws; Republic): the assumption that religion has been already settled by the oracle of Delphi (Laws; Republic), to which an appeal is also made in special cases (Laws): the notion of the battle with self, a paradox for which Plato in a manner apologizes both in the Laws and the Republic: the remark (Laws) that just men, even when they are deformed in body, may still be perfectly beautiful in respect of the excellent justice of their minds (compare Republic): the argument that ideals are none the worse because they cannot be carried out (Laws; Republic): the near approach to the idea of good in 'the principle which is common to all the four virtues,' a truth which the guardians must be compelled to recognize (Laws; compare Republic): or again the recognition by reason of the right pleasure and pain, which had previously been matter of habit (Laws; Republic): or the blasphemy of saying that the excellency of music is to give pleasure (Laws; Republic): again the story of the Sidonian Cadmus (Laws), which is a variation of the Phoenician tale of the earth-born men (Republic): the comparison of philosophy to a yelping she-dog, both in the Republic and in the Laws: the remark that no man can practise two trades (Laws; Republic): or the advantage of the middle condition (Laws; Republic): the tendency to speak of principles as moulds or forms; compare the ekmageia of song (Laws), and the tupoi of religion (Republic): or the remark (Laws) that 'the relaxation of justice makes many cities out of one,' which may be compared with the Republic: or the description of lawlessness 'creeping in little by little in the fashions of music and overturning all things,' – to us a paradox, but to Plato's mind a fixed idea, which is found in the Laws as well as in the Republic: or the figure of the parts of the human body under which the parts of the state are described (Laws; Republic): the apology for delay and diffuseness, which occurs not unfrequently in the Republic, is carried to an excess in the Laws (compare Theaet.): the remarkable thought (Laws) that the soul of the sun is better than the sun, agrees with the relation in which the idea of good stands to the sun in the Republic, and with the substitution of mind for the idea of good in the Philebus: the passage about the tragic poets (Laws) agrees generally with the treatment of them in the Republic, but is more finely conceived, and worked out in a nobler spirit. Some lesser similarities of thought and manner should not be omitted, such as the mention of the thirty years' old students in the Republic, and the fifty years' old choristers in the Laws; or the making of the citizens out of wax (Laws) compared with the other image (Republic); or the number of the tyrant (729), which is NEARLY equal with the number of days and nights in the year (730), compared with the 'slight correction' of the sacred number 5040, which is divisible by all the numbers from 1 to 12 except 11, and divisible by 11, if two families be deducted; or once more, we may compare the ignorance of solid geometry of which he complains in the Republic and the puzzle about fractions with the difficulty in the Laws about commensurable and incommensurable quantities – and the malicious emphasis on the word gunaikeios (Laws) with the use of the same word (Republic). These and similar passages tend to show that the author of the Republic is also the author of the Laws. They are echoes of the same voice, expressions of the same mind, coincidences too subtle to have been invented by the ingenuity of any imitator. The force of the argument is increased, if we remember that no passage in the Laws is exactly copied, – nowhere do five or six words occur together which are found together elsewhere in Plato's writings.
In other dialogues of Plato, as well as in the Republic, there are to be found parallels with the Laws. Such resemblances, as we might expect, occur chiefly (but not exclusively) in the dialogues which, on other grounds, we may suppose to be of later date. The punishment of evil is to be like evil men (Laws), as he says also in the Theaetetus. Compare again the dependence of tragedy and comedy on one another, of which he gives the reason in the Laws – 'For serious things cannot be understood without laughable, nor opposites at all without opposites, if a man is really to have intelligence of either'; here he puts forward the principle which is the groundwork of the thesis of Socrates in the Symposium, 'that the genius of tragedy is the same as that of comedy, and that the writer of comedy ought to be a writer of tragedy also.' There is a truth and right which is above Law (Laws), as we learn also from the Statesman. That men are the possession of the Gods (Laws), is a reflection which likewise occurs in the Phaedo. The remark, whether serious or ironical (Laws), that 'the sons of the Gods naturally believed in the Gods, because they had the means of knowing about them,' is found in the Timaeus. The reign of Cronos, who is the divine ruler (Laws), is a reminiscence of the Statesman. It is remarkable that in the Sophist and Statesman (Soph.), Plato, speaking in the character of the Eleatic Stranger, has already put on the old man. The madness of the poets, again, is a favourite notion of Plato's, which occurs also in the Laws, as well as in the Phaedrus, Ion, and elsewhere. There are traces in the Laws of the same desire to base speculation upon history which we find in the Critias. Once more, there is a striking parallel with the paradox of the Gorgias, that 'if you do evil, it is better to be punished than to be unpunished,' in the Laws: 'To live having all goods without justice and virtue is the greatest of evils if life be immortal, but not so great if the bad man lives but a short time.'
The point to be considered is whether these are the kind of parallels which would be the work of an imitator. Would a forger have had the wit to
