endless road may change the whole character of the perspective. You cannot, as the Sophist proposed to do (that was part of his foolishness) take and put truth into the soul. If you could, it might be established there, only as an "inward lie," as a mistake. "Must I take the argument, and literally insert it into your mind?" asks Thrasymachus. "Heaven forbid": answers Socrates. That is precisely what he fears most, for himself, and for others; and from first to last, demands, as the first condition of comradeship [191] in that long journey in which he conceives teacher and learner to be but fellow- travellers, pilgrims side by side, sincerity, above all sincerity with one's self--that, and also freedom in reply. "Answer what you think, megaloprepôs +--liberally." For it is impossible to make way otherwise, in a method which consists essentially in the development of knowledge by question and answer. Misuse, again, is of course possible in a method which admits of no objective sanction or standard; the success of which depends on a loyalty to one's self, in the prosecution of it, of which no one else can be cognisant. And if we can misuse it with ourselves, how much more certainly can the expert abuse it with another. At every turn of the conversation, a door lies open to sophistry. Sophistry, logomachy, eristic: we may learn what these are, sometimes, from Plato's own practice. That justice is only useful as applied to things useless; that the just man is a kind of thief; and the like; is hardly so much as sophistry. And this too was possible in a method, which, with all its large outlook, has something of the irregularity, the accident, the heats and confusion, of life itself--a method of reasoning which can only in a certain measure be reasoned upon. How different the exactness which Aristotle supposes, and does his best to secure, in scientific procedure! For him, dialectic, Platonic dialectic, is, at best, a part of "eristic" [192] --of the art, or trick, of merely popular and approximate debate, in matters where science is out of the question, and rhetoric has its office, not in providing for the intelligence, but in moulding the sentiments and the will. Conversely to that absoluteness and necessity which Plato himself supposes in all real knowledge, as "the spectacle of all time and all existence," it might seem that the only sort of truth attainable by his actual method, must be the truth of a particular time and place, for one and not for another. Dialogos peirastikos,+ "a Dialogue of search":--every one of Plato's Dialogues is in essence such like that whole, life-long, endless dialogue which dialectic, in its largest scope, does but formulate, and in which truly the last, the infallible word, after all, never gets spoken. Our pilgrimage is meant indeed to end in nothing less than the vision of what we seek. But can we ever be quite sure that we are really come to that? By what sign or test?
