Oration, the Phaedo, etc., have an inferior degree of evidence in their favour. They may have been supposed by him to be the writings of another, although in the case of really great works, e.g. the Phaedo, this is not credible; those again which are quoted but not named, are still more defective in their external credentials. There may be also a possibility that Aristotle was mistaken, or may have confused the master and his scholars in the case of a short writing; but this is inconceivable about a more important work, e.g. the Laws, especially when we remember that he was living at Athens, and a frequenter of the groves of the Academy, during the last twenty years of Plato's life. Nor must we forget that in all his numerous citations from the Platonic writings he never attributes any passage found in the extant dialogues to any one but Plato. And lastly, we may remark that one or two great writings, such as the Parmenides and the Politicus, which are wholly devoid of Aristotelian (1) credentials may be fairly attributed to Plato, on the ground of (2) length, (3) excellence, and (4) accordance with the general spirit of his writings. Indeed the greater part of the evidence for the genuineness of ancient Greek authors may be summed up under two heads only: (1) excellence; and (2) uniformity of tradition--a kind of evidence, which though in many cases sufficient, is of inferior value.
Proceeding upon these principles we appear to arrive at the conclusion that nineteen-twentieths of all the writings which have ever been ascribed to Plato, are undoubtedly genuine. There is another portion of them, including the Epistles, the Epinomis, the dialogues rejected by the ancients themselves, namely, the Axiochus, De justo, De virtute, Demodocus, Sisyphus, Eryxias, which on grounds, both of internal and external evidence, we are able with equal certainty to reject. But there still remains a small portion of which we are unable to affirm either that they are genuine or spurious. They may have been written in youth, or possibly like the works of some painters, may be partly or wholly the compositions of pupils; or they may have been the writings of some contemporary transferred by accident to the more celebrated name of Plato, or of some Platonist in the next generation who aspired to imitate his master. Not that on grounds either of language or philosophy we should lightly reject them. Some difference of style, or inferiority of execution, or inconsistency of thought, can hardly be considered decisive of their spurious character. For who always does justice to himself, or who writes with equal care at all times? Certainly not Plato, who exhibits the greatest differences in dramatic power, in the formation of sentences, and in the use of words, if his earlier writings are compared with his later ones, say the Protagoras or Phaedrus with the Laws. Or who can be expected to think in the same manner during a period of authorship extending over above fifty years, in an age of great intellectual activity, as well as of political and literary transition? Certainly not Plato, whose earlier writings are separated from his later ones by as wide an interval of philosophical speculation as that which separates his later writings from Aristotle.
The dialogues which have been translated in the first Appendix, and which appear to have the next claim to genuineness among the Platonic writings, are the Lesser Hippias, the Menexenus or Funeral Oration, the First Alcibiades. Of these, the Lesser Hippias and the Funeral Oration are cited by Aristotle; the first in the Metaphysics, the latter in the Rhetoric. Neither of them are expressly attributed to Plato, but in his citation of both of them he seems to be referring to passages in the extant dialogues. From the mention of 'Hippias' in the singular by Aristotle, we may perhaps infer that he was unacquainted with a second dialogue bearing the same name. Moreover, the mere existence of a Greater and Lesser Hippias, and of a First and Second Alcibiades, does to a certain extent throw a doubt upon both of them. Though a very clever and ingenious work, the Lesser Hippias does not appear to contain anything beyond the power of an imitator, who was also a careful student of the earlier Platonic writings, to invent. The motive or leading thought of the dialogue may be detected in Xen. Mem., and there is no similar instance of a 'motive' which is taken from Xenophon in an undoubted dialogue of Plato. On the other hand, the upholders of the genuineness of the dialogue will find in the Hippias a true Socratic spirit; they will compare the Ion as being akin both in subject and treatment; they will urge the authority of Aristotle; and
