fostered. Fanaticism consists in redoubling your effort when you have forgotten your aim.
An earnestness which is out of proportion to any knowledge or love of real things, which is therefore dark and inward and thinks itself deeper than the earth's foundations—such an earnestness, until culture turns it into intelligent interests, will naturally breed a new mythology. It will try to place some world of Afrites and shadowy giants behind the constellations, which it finds too distinct and constant to be its companions or supporters; and it will assign to itself vague and infinite tasks, for which it is doubtless better equipped than for those which the earth now sets before it. Even these, however, since they are parts of an infinite whole, the mystic may (histrionically, perhaps, yet zealously) undertake; but as his eye will be perpetually fixed on something invisible beyond, and nothing will be done for its own sake or enjoyed in its own fugitive presence, there will be little art and little joy in existence. All will be a tossing servitude and illiberal mist, where the parts will have no final values and the whole no pertinent direction.
The Greeks thought straight in both physics and morals.
In Greek philosophy the situation is far more auspicious. The ancients led a rational life and envisaged the various spheres of speculation as men might whose central interests were rational. In physics they leaped at once to the conception of a dynamic unity and general evolution, thus giving that background to human life which shrewd observation would always have descried, and which modern science has laboriously rediscovered. Two great systems offered, in two legitimate directions, what are doubtless the final and radical accounts of physical being. Heraclitus, describing the immediate, found it to be in constant and pervasive change: no substances, no forms, no identities could be arrested there, but as in the human soul, so in nature, all was instability, contradiction, reconstruction, and oblivion. This remains the empirical fact; and we need but to rescind the artificial division which Descartes has taught us to make between nature and life, to feel again the absolute aptness of Heraclitus's expressions. These were thought obscure only because they were so disconcertingly penetrating and direct. The immediate is what nobody sees, because convention and reflection turn existence, as soon as they can, into ideas; a man who discloses the immediate seems profound, yet his depth is nothing but innocence recovered and a sort of intellectual abstention. Mysticism, scepticism, and transcendentalism have all in their various ways tried to fall back on the immediate; but none of them has been ingenuous enough. Each has added some myth, or sophistry, or delusive artifice to its direct observation. Heraclitus remains the honest prophet of immediacy: a mystic without raptures or bad rhetoric, a sceptic who does not rely for his results on conventions unwittingly adopted, a transcendentalist without false pretensions or incongruous dogmas.
Heraclitus and the immediate.
The immediate is not, however, a good subject for discourse, and the expounders of Heraclitus were not unnaturally blamed for monotony. All they could do was to iterate their master's maxim, and declare everything to be in flux. In suggesting laws of recurrence and a reason in which what is common to many might be expressed, Heraclitus had opened the door into another region: had he passed through, his philosophy would have been greatly modified, for permanent forms would have forced themselves on his attention no less than shifting materials. Such a Heraclitus would have anticipated Plato; but the time for such a synthesis had not yet arrived.
Democritus and the naturally intelligible.
At the opposite pole from immediacy lies intelligibility. To reduce phenomena to constant elements, as similar and simple as possible, and to conceive their union and separation to obey constant laws, is what a natural philosopher will inevitably do so soon as his interest is not merely to utter experience but to understand it. Democritus brought this scientific ideal to its ultimate expression. By including psychic existence in his atomic system, he indicated a problem which natural science has since practically abandoned but which it may some day be compelled to take up. The atoms of Democritus seem to us gross, even for chemistry, and their quality would have to undergo great transformation if they were to support intelligibly psychic being as well; but that very grossness and false simplicity had its merits, and science must be for ever grateful to the man who at its inception could so clearly formulate its mechanical ideal. That the world is not so intelligible as we could wish is not to be wondered at. In other respects also it fails to respond to our ideals; yet our hope must be to find it more propitious to the intellect as well as to all the arts in proportion as we learn better how to live in it.
The atoms of what we call hydrogen or oxygen may well turn out to be worlds, as the stars are which make atoms for astronomy. Their inner organisation might be negligible on our rude plane of being; did it disclose itself, however, it would be intelligible in its turn only if constant parts and constant laws were discernible within each system. So that while atomism at a given level may not be a final or metaphysical truth, it will describe, on every level, the practical and efficacious structure of the world. We owe to Democritus this ideal of practical intelligibility; and he is accordingly an eternal spokesman of reason. His system, long buried with other glories of the world, has been partly revived; and although it cannot be verified in haste, for it represents an ultimate ideal, every advance in science reconstitutes it in some particular. Mechanism is not one principle of explanation among others. In natural philosophy, where to explain means to discover origins, transmutations, and laws, mechanism is explanation itself.
Heraclitus had the good fortune of having his physics absorbed by Plato. It is a pity that Democritus' physics was not absorbed by Aristotle. For with the flux observed, and mechanism conceived to explain it, the theory of existence is complete; and had a complete physical theory been incorporated into the Socratic philosophy, wisdom would have lacked none of its parts. Democritus, however, appeared too late, when ideal science had overrun the whole field and initiated a verbal and dialectical physics; so that Aristotle, for all his scientific temper and studies, built his natural philosophy on a lamentable misunderstanding, and condemned thought to confusion for two thousand years.
Socrates and the autonomy of mind.
If the happy freedom of the Greeks from religious dogma made them the first natural philosophers, their happy political freedom made them the first moralists. It was no accident that Socrates walked the Athenian agora; it was no petty patriotism that made him shrink from any other scene. His science had its roots there, in the personal independence, intellectual vivacity, and clever dialectic of his countrymen. Ideal science lives in discourse; it consists in the active exercise of reason, in signification, appreciation, intent, and self-expression. Its sum total is to know oneself, not as psychology or anthropology might describe a man, but to know, as the saying is, one's own mind. Nor is he who knows his own mind forbidden to change it; the dialectician has nothing to do with future possibilities or with the opinion of anyone but the man addressed. This kind of truth is but adequate veracity; its only object is its own intent. Having developed in the spirit the consciousness of its meanings and purposes, Socrates rescued logic and ethics for ever from authority. With his friends the Sophists, he made man the measure of all things, after bidding him measure himself, as they neglected to do, by his own ideal. That brave humanity which had first raised its head in Hellas and had endowed so many things in heaven and earth, where everything was hitherto monstrous, with proportion and use, so that man's works might justify themselves to his mind, now found in Socrates its precise definition; and it was naturally where the Life of Reason had been long cultivated that it came finally to be conceived.
Plato gave the ideal its full expression.
Socrates had, however, a plebeian strain in his humanity, and his utilitarianism, at least in its expression, hardly did justice to what gives utility to life. His condemnation for atheism—if we choose to take it symbolically—was not altogether unjust: the gods of Greece were not honoured explicitly enough in his philosophy. Human good appeared there in its principle; you would not set a pilot to mend shoes, because you knew your own purpose; but what purposes a civilised soul might harbour, and in what highest shapes the good might appear, was a problem that
