[187] Plato, who supposes any knowledge worth the name to be "absolute and eternal"; whose constant contention it is, to separate longo intervallo, by the longest possible interval, science (epistêmê)+ as the possession of irresistible truth, from any and every sort of knowledge which falls short of that; would hardly have accepted the suggestion of Lessing. Yet, in spite of all that, in spite of the demand he makes for certainty and exactness and what is absolute, in all real knowledge, he does think, or inclines his reader to think, that truth, precisely because it resembles some high kind of relationship of persons to persons, depends a good deal on the receiver; and must be, in that degree, elusive, provisional, contingent, a matter of various approximation, and of an "economy," as is said; that it is partly a subjective attitude of mind:—that philosophic truth consists in the philosophic temper. "Socrates in Plato," remarks Montaigne acutely, "disputes, rather to the profit of the disputants, than of the dispute. He takes hold of the first subject, like one who has a more profitable end in view than to explain it; namely, to clear the understandings that he takes upon him to instruct and exercise."

Just there, in fact, is the justification of Plato's peculiar dialectical method, of its inexactness, its hesitancy, its scruples and reserve, as if he feared to obtrude knowledge on an unworthy receiver. The treatise, as the proper instrument of dogma [188] —the Ethics of Aristotle, the Ethics of Spinoza—begins with a truth, or with a clear conviction of truth, in the axiom or definition, which it does but propose further to explain and apply.—The treatise, as the instrument of a dogmatic philosophy begins with an axiom or definition: the essay or dialogue, on the other hand, as the instrument of dialectic, does not necessarily so much as conclude in one; like that long dialogue with oneself, that dialectic process, which may be co-extensive with life. It does in truth little more than clear the ground, as we say, or the atmosphere, or the mental tablet, that one may have a fair chance of knowing, or seeing, perhaps: it does but put one into a duly receptive attitude towards such possible truth, discovery, or revelation, as may one day occupy the ground, the tablet,—shed itself on the purified air; it does not provide a proposition, nor a system of propositions, but forms a temper.

What Plato presents to his readers is then, again, a paradox, or a reconciliation of opposed tendencies: on one side, the largest possible demand for infallible certainty in knowledge (it was he fixed that ideal of absolute truth, to which, vainly perhaps, the human mind, as such, aspires) yet, on the other side, the utmost possible inexactness, or contingency, in the method by which actually he proposes to attain it. It has been said that the humour of Socrates, of which the [189] famous Socratic irony—the pretence to have a bad memory, to dislike or distrust long and formal discourse, to have taught nothing, to be but a mid-wife in relation to other people's thoughts—was an element, is more than a mere personal trait; that it was welcome as affording a means of escape from the full responsibilities of his teaching. It belonged, in truth, to the tentative character of dialectic, of question and answer as the method of discovery, of teaching and learning, to the position, in a word, of the philosophic essayist. That it was thus, might be illustrated abundantly from the Platonic dialogues. The irony, the Socratic humour, so serviceable to a diffident teacher, are, in fact, Plato's own. Kindyneuei,+ "it may chance to be," is, we may notice, a favourite catchword of his. The philosopher of Being, or, of the verb, "To be," is after all afraid of saying, "It is."

For, again, person dealing with person—with possible caprice, therefore, at least on one side—or intelligence with intelligence, is what Plato supposes in the reception of truth:—that, and not an exact mechanism, a precise machine, operating on, or with, an exactly ponderable matter. He has fears for truth, however carefully considered. To the very last falsehood will lurk, if not about truth itself, about this or that assent to it. The receiver may add the falsities of his own nature to the truth he receives. The proposition which embodies it very [190] imperfectly, may not look to him, in those dark chambers of his individuality, of himself, into which none but he can ever get, to test the matter, what it looks to me, or to you. We may not even be thinking of, not looking at, the same thing, when we talk of Beauty, and the like; objects which, after all, to the Platonist are matters of theôria,+ of immediate intuition, of immediate vision, or, as Plato sometimes fancied, of an earlier personal experience; and which, as matter of such intuition, are incapable of analysis, and therefore, properly, incommunicable by words. Place, then, must be left to the last in any legitimate dialectic process for possible after-thoughts; for the introduction, so to speak, of yet another interlocutor in the dialogue, which has, in fact, no necessary conclusion, and leaves off only because time is up, or when, as he says, one leaves off seeking through weariness (apokamnôn).+ "What thought can think, another thought can mend." Another turn in the 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?

Now oppose all this, all these peculiarities of the Platonic method, as we find it, to the exact and formal method of Aristotle, of Aquinas, of Spinoza, or Hegel; and then suppose one trained exclusively on Plato's dialogues. Is it the eternal certainty, after all, the immutable and absolute character of truth, as Plato conceived it, that he would be likely to apprehend? We have here another of those contrasts of tendency, constitutional [193] in the genius of Plato, and which may add to our interest in him. Plato is to be explained, as we say, or interpreted, partly through his predecessors, and his contemporaries; but in part also by his followers, by the light his later mental kinsmen throw back on the conscious or unconscious drift of his teaching. Now there are in the history of philosophy two opposite Platonic traditions; two legitimate yet divergent streams of influence from him. Two very different yet equally representative scholars we may see in thought emerging from his school. The "theory of the Ideas," the high ideal, the uncompromising demand for absolute certainty, in any truth or knowledge worthy of the name; the immediate or intuitive character of the highest acts of knowledge; that all true theory is indeed "vision":—for the maintenance of that side of the Platonic position we must look onward to Aristotle, and the Schoolmen of all ages, to Spinoza, to Hegel; to those mystic aspirants to "vision" also, the so-called Neo-Platonists of all ages, from Proclus to Schelling. From the abstract, metaphysical systems of those, the ecstasy and illuminism of these, we may mount up to the actual words of Plato in the Symposium, the fifth book of The Republic, the Phaedrus.

But it is in quite different company we must look for the tradition, the development, of Plato's actual method of learning and teaching. The Academy of Plato, the established seat of his [194] philosophy, gave name to a school, of which Lucian, in Greek, and in Latin, Cicero, are the proper representatives,—Cicero, the perfect embodiment of what is still sometimes understood to be the "academic spirit," surveying all sides, arraying evidence, ascertaining, measuring, balancing, tendencies, but ending in suspension of judgment. If Platonism from age to age has meant, for some, ontology, a doctrine of "being," or the nearest attainable approach to or substitution for that; for others, Platonism has been in fact only another name for scepticism, in a recognisable philosophic tradition. Thus, in the Middle Age, it qualifies in the Sic et Non the confident scholasticism of Abelard. It is like the very trick and impress of the Platonic Socrates himself again, in those endless conversations of Montaigne—that typical sceptic of the age of the Renaissance—conversations with himself, with the living, with the dead through their writings, which his Essays do but reflect. Typical Platonist or sceptic, he is therefore also the typical essayist. And the sceptical philosopher of Bordeaux does but commence the modern world, which, side by side with its metaphysical reassertions, from Descartes to Hegel, side by side also with a constant accumulation of the sort of certainty which is afforded by empirical science, has had assuredly, to check wholesomely the pretensions of one and of the other alike, its doubts.—"Their name is legion," says a modern writer. Reverent [195] and irreverent, reasonable and unreasonable, manly and unmanly, morbid and healthy, guilty and honest, wilful, inevitable—they have been called, indifferently, in an age which thirsts for intellectual security, but cannot make up its mind. Q'ue scais-je? it cries, in the words of Montaigne; but in the spirit also of the Platonic Socrates, with whom such dubitation had been nothing less than a religious duty or service.

Sanguine about any form of absolute knowledge, of eternal, or indefectible, or immutable truth, with our modern temperament as it is, we shall hardly become, even under the direction of Plato, and by the reading of the Platonic Dialogues. But if we are little likely to realise in his school, the promise of "ontological" science, of a "doctrine of Being," or any increase in our consciousness of metaphysical security, are likely, rather, to acquire there that other sort of Platonism, a habit, namely, of tentative thinking and suspended judgment, if we are not likely to enjoy the vision of his "eternal and immutable ideas," Plato may yet promote in us what we call "ideals"— the aspiration towards a more perfect Justice, a more perfect Beauty, physical and intellectual, a more perfect condition of human affairs, than any one has ever yet seen; that kosmos,+ in which things are only as they are thought by a perfect mind, to which experience is constantly approximating us, but which it does not provide. There they stand, the two [196] great landmarks of the intellectual or spiritual life as Plato conceived it: the ideal, the world of "ideas," "the great perhaps," for which it is his merit so effectively to have opened room in the mental scheme, to be known by us, if at all, through our affinities of nature with it, which, however, in our dealings with ourselves and others we may assume to be objective or real:—and then, over against our imperfect realisation of that ideal, in ourselves, in nature and history, amid the personal caprices (it might almost seem) of its discovery of itself to us, as the appropriate attitude on our part, the dialectical spirit, which to the last will have its diffidence and reserve, its scruples and second thoughts. Such condition of suspended judgment indeed, in its more genial development and under felicitous culture, is but the expectation, the receptivity, of the faithful scholar, determined not to foreclose what is still a question—the "philosophic temper," in short, for which a survival of query will be still the salt of truth, even in the most absolutely ascertained knowledge.
