Plato is usually extolled by his admirers, as the champion of the Absolute — of unchangeable forms, immutable truth, objective necessity cogent and binding on every one. He is praised for having refuted Protagoras; who can find no standard beyond the individual recognition and belief, of his own mind or that of some one else. There is no doubt that Plato often talks in that strain: but the method followed in his dialogues, and the general principles of method which he lays down, here as well as elsewhere, point to a directly opposite conclusion. Of this the Phædrus is a signal instance. Instead of the extreme of generality, it proclaims the extreme of specialty. The objection which the Sokrates of the Phædrus advances against the didactic efficacy of written discourse, is founded on the fact, that it is the same to all readers — that it takes no cognizance of the differences of individual minds nor of the same mind at different times. Sokrates claims for dialectic debate the valuable privilege, that it is constant action and re-action between two individual minds — an appeal by the inherent force and actual condition of each, to the like elements in the other — an ever shifting presentation of the same topics, accommodated to the measure of intelligence and cast of emotion in the talkers and at the moment. The individuality of each mind — both questioner and respondent — is here kept in view as the governing condition of the process. No two minds can be approached by the same road or by the same interrogation. The questioner cannot advance a step except by the admission of the respondent. Every respondent is the measure to himself. He answers suitably to his own belief; he defends by his own suggestions; he yields to the pressure of contradiction and inconsistency, when he feels them, and not before. Each dialogist is (to use the Protagorean phrase) the measure to himself of truth and falsehood, according as he himself believes it. Assent or dissent, whichever it may be, springs only from the free working of the individual mind, in its actual condition then and there. It is to the individual mind alone, that appeal is made, and this is what Protagoras asks for.
We thus find, in Plato’s philosophical character, two extreme opposite tendencies and opposite poles co-existent. We must recognise them both: but they can never be reconciled: sometimes he obeys and follows the one, sometimes the other.
If it had been Plato’s purpose to proclaim and impose upon every one something which he called “Absolute Truth,” one and the same alike imperative upon all — he would best proclaim it by preaching or writing. To modify this “Absolute,” according to the varieties of the persons addressed, would divest it of its intrinsic attribute and excellence. If you pretend to deal with an Absolute, you must turn away your eyes from all diversity of apprehending intellects and believing subjects.
CHAPTER XXVII.
PARMENIDES.
Character of dialogues immediately preceding — much transcendental assertion. Opposite character of the Parmenides.
In the dialogues immediately preceding — Phædon, Phædrus, Symposion — we have seen Sokrates manifesting his usual dialectic, which never fails him: but we have also seen him indulging in a very unusual vein of positive affirmation and declaration. He has unfolded many novelties about the states of pre-existence and post-existence: he has familiarised us with Ideas, Forms, Essences, eternal and unchangeable, as the causes of all the facts and particularities of nature: he has recognised the inspired variety of madness, as being more worthy of trust than sober, uninspired, intelligence: he has recounted, with the faith of a communicant fresh from the mysteries, revelations made to him by the prophetess Diotima, — respecting the successive stages of exaltation whereby gifted intelligences, under the stimulus of Eros Philosophus, ascend into communion with the great sea of Beauty. All this is set forth with as much charm as Plato’s eloquence can bestow. But after all, it is not the true character of Sokrates:— I mean, the Sokrates of the Apology, whose mission it is to make war against the chronic malady of the human mind — false persuasion of knowledge, without the reality. It is, on the contrary, Sokrates himself infected with the same chronic malady which he combats in others, and requiring medicine against it as much as others. Such is the exact character in which Sokrates appears in the Parmenides: which dialogue I shall now proceed to review.
Sokrates is the juvenile defendant — Parmenides the veteran censor and cross-examiner. Parmenides gives a specimen of exercises to be performed by the philosophical aspirant.
The Parmenides announces its own purpose as intended to repress premature forwardness of affirmation, in a young philosophical aspirant: who, with meritorious eagerness in the search for truth, and with his eyes turned in the right direction to look for it — has nevertheless not fully estimated the obstructions besetting his path, nor exercised himself in the efforts necessary to overcome them. By a curious transposition, or perhaps from deference on Plato’s part to the Hellenic sentiment of Nemesis, — Sokrates, who in most Platonic dialogues stands forward as the privileged censor and victorious opponent, is here the juvenile defendant under censorship by a superior. It is the veteran Parmenides of Elea who, while commending the speculative impulse and promise of Sokrates, impresses upon him at the same time that the theory which he had advanced — the self-existence, the separate and substantive nature, of Ideas — stands exposed to many grave objections, which he (Sokrates) has not considered and cannot meet. So far, Parmenides performs towards Sokrates the same process of cross-examining refutation as Sokrates himself applies to Theætêtus and other young men elsewhere. But we find in this dialogue something ulterior and even peculiar. Having warned Sokrates that his intellectual training has not yet been carried to a point commensurate with the earnestness of his aspirations — Parmenides proceeds to describe to him what exercises he ought to go through, in order to guard himself against premature assertion or hasty partiality. Moreover, Parmenides not only indicates in general terms what ought to be done, but illustrates it by giving a specimen of such exercise, on a topic chosen by himself.
