Three Philosophical Poets by George Santayana (free children's ebooks pdf TXT) 📖

a coxcomb. It is his intellectual vision that the naturalist in particular wishes to hand down to posterity, not the shabby incidents that preceded that vision in his own person. These incidents, even if they were by chance interesting, could not be repeated in us; but the vision into which the thinker poured his faculties, and to which he devoted his vigils, is communicable to us also, and may become a part of ourselves.

Since Lucretius is thus identical for us with his poem, and is lost in his philosophy, the antecedents of Lucretius are simply the stages by which his conception of nature first shaped itself in the human mind. To retrace these stages is easy; some of them are only too familiar; yet the very triteness of the subject may blind us to the grandeur and audacity of the intellectual feat involved. A naturalistic conception of things is a great work of imagination,—greater, I think, than any dramatic or moral mythology: it is a conception fit to inspire great poetry, and in the end, perhaps, it will prove the only conception able to inspire it.

We are told of the old Xenophanes that he looked up into the round heaven and cried, "The All is One." What is logically a truism may often be, imaginatively, a great discovery, because no one before may have thought of the obvious analogy which the truism registers. So, in this case, the unity of all things is logically an evident, if barren, truth; for the most disparate and unrelated worlds would still be a multitude, and so an aggregate, and so, in some sense, a unity. Yet it was a great imaginative feat to cast the eye deliberately round the entire horizon, and to draw mentally the sum of all reality, discovering that reality makes such a sum, and may be called one; as any stone or animal, though composed of many parts, is yet called one in common parlance. It was doubtless some prehistoric man of genius, long before Xenophanes, who first applied in this way to all things together that notion of unity and wholeness which everybody had gained by observation of things singly, and who first ventured to speak of "the world." To do so is to set the problem for all natural philosophy, and in a certain measure to anticipate the solution of that problem; for it is to ask how things hang together, and to assume that they do hang together in one way or another.

To cry "The All is One," and to perceive that all things are in one landscape and form a system by their juxtaposition, is the rude beginning of wisdom in natural philosophy. But it is easy to go farther, and to see that things form a unity in a far deeper and more mysterious way. One of the first things, for instance, that impresses the poet, the man of feeling and reflection, is that these objects that people the world all pass away, and that the place there-of knows them no more. Yet, when they vanish, nothingness does not succeed; other things arise in their stead. Nature remains always young and whole in spite of death at work everywhere; and what takes the place of what continually disappears is often remarkably like it in character. Universal instability is not incompatible with a great monotony in things; so that while Heraclitus lamented that everything was in flux, Ecclesiastes, who was also entirely convinced of that truth, could lament that there was nothing new under the sun.

This double experience of mutation and recurrence, an experience at once sentimental and scientific, soon brought with it a very great thought, perhaps the greatest thought that mankind has ever hit upon, and which was the chief inspiration of Lucretius. It is that all we observe about us, and ourselves also, may be so many passing forms of a permanent substance. This substance, while remaining the same in quantity and in inward quality, is constantly redistributed; in its redistribution it forms those aggregates which we call things, and which we find constantly disappearing and reappearing. All things are dust, and to dust they return; a dust, however, eternally fertile, and destined to fall perpetually into new, and doubtless beautiful, forms. This notion of substance lends a much greater unity to the outspread world; it persuades us that all things pass into one another, and have a common ground from which they spring successively, and to which they return.

The spectacle of inexorable change, the triumph of time, or whatever we may call it, has always been a favourite theme for lyric and tragic poetry, and for religious meditation. To perceive universal mutation, to feel the vanity of life, has always been the beginning of seriousness. It is the condition for any beautiful, measured, or tender philosophy. Prior to that, everything is barbarous, both in morals and in poetry; for until then mankind has not learned to renounce anything, has not outgrown the instinctive egotism and optimism of the young animal, and has not removed the centre of its being, or of its faith, from the will to the imagination.

To discover substance, then, is a great step in the life of reason, even if substance be conceived quite negatively as a term that serves merely to mark, by contrast, the unsubstantiality, the vanity, of all particular moments and things. That is the way in which Indian poetry and philosophy conceived substance. But the step taken by Greek physics, and by the poetry of Lucretius, passes beyond. Lucretius and the Greeks, in observing universal mutation and the vanity of life, conceived behind appearance a great intelligible process, an evolution in nature. The reality became interesting, as well as the illusion. Physics became scientific, which had previously been merely spectacular.

Here was a much richer theme for the poet and philosopher, who was launched upon the discovery of the ground and secret causes of this gay or melancholy flux. The understanding that enabled him to discover these causes did for the European what no Indian mystic, what no despiser of understanding anywhere, suffers himself to do; namely, to dominate, foretell, and transform this changing show with a virile, practical intelligence. The man who discovers the secret springs of appearances opens to contemplation a second positive world, the workshop and busy depths of nature, where a prodigious mechanism is continually supporting our life, and making ready for it from afar by the most exquisite adjustments. The march of this mechanism, while it produces life and often fosters it, yet as often makes it difficult and condemns it to extinction. This truth, which the conception of natural substance first makes intelligible, justifies the elegies which the poets of illusion and disillusion have always written upon human things. It is a truth with a melancholy side; but being a truth, it satisfies and exalts the rational mind, that craves truth as truth, whether it be sad or comforting, and wishes to pursue a possible, not an impossible, happiness.

So far, Greek science had made out that the world was one, that there was a substance, that this was a physical substance, distributed and moving in space. It was matter. The question remained, What is the precise nature of matter, and how does it produce the appearances we observe? The only answer that concerns us here is that given by Lucretius; an answer he accepted from Epicurus, his master in everything, who in turn had accepted it from Democritus. Now Democritus had made a notable advance over the systems that selected one obvious substance, like water, or collected all the obvious substances, as Anaxagoras had done, and tried to make, the world out of them. Democritus thought that the substance of everything ought not to have any of the qualities present in some things and absent in others; it ought to have only the qualities present in all things. It should be merely matter. Materiality, according to him, consisted of extension, figure, and solidity; in the thinnest ether, if we looked sharp enough, we should find nothing but particles possessing these properties. All other qualities of things were apparent only, and imputed to them by a convention of the mind. The mind was a born mythologist, and projected its feelings into their causes. Light, colour, taste, warmth, beauty, excellence, were such imputed and conventional qualities; only space and matter were real. But empty space was no less real than matter. Consequently, although the atoms of matter never changed their form, real changes could take place in nature, because their position might change in a real space.

Unlike the useless substance of the Indians, the substance of Democritus could offer a calculable, ground for the flux of appearances; for this substance was distributed unequally in the void, and was constantly moving. Every appearance, however fleeting, corresponded to a precise configuration of substance; it arose with that configuration and perished with it. This substance, accordingly, was physical, not metaphysical. It was no dialectical term, but a scientific anticipation, a prophecy as to what an observer who should be properly equipped would discover in the interior of bodies. Materialism is not a system of metaphysics; it is a speculation in chemistry and physiology, to the effect that, if analysis could go deep enough, it would find that all substance was homogeneous, and that all motion was regular.

Though matter was homogeneous, the forms of the ultimate particles, according to Democritus, were various; and sundry combinations of them constituted the sundry objects in nature. Motion was not, as the vulgar (and Aristotle) supposed, unnatural, and produced magically by some moral cause; it had been eternal and was native to the atoms. On striking, they rebounded; and the mechanical currents or vortices which these contacts occasioned formed a multitude of stellar systems, called worlds, with which infinite space was studded.

Mechanism as to motion, atomism as to structure, materialism as to substance, that is the whole system of Democritus. It is as wonderful in its insight, in its sense for the ideal demands of method and understanding, as it is strange and audacious in its simplicity. Only the most convinced rationalist, the boldest prophet, could embrace it dogmatically; yet time has largely given it the proof. If Democritus could look down upon the present state of science, he would laugh, as he was in the habit of doing, partly at the confirmation we can furnish to portions of his philosophy, and partly at our stupidity that cannot guess the rest.

There are two maxims in Lucretius that suffice, even to this day, to distinguish a thinker who is a naturalist from one who is not. "Nothing," he says, "arises in the body in order that we may use it, but what arises brings forth its use."[1] This is that discarding of final causes on which all progress in science depends. The other maxim runs:" One thing will grow plain when compared with another: and blind night shall not obliterate the path for thee, before thou hast thoroughly scanned the ultimate things of nature; so much will things throw light on things."[2] Nature is her own standard; and if she seems to us unnatural, there is no hope for our minds.

The ethics of Democritus, in so far as we may judge from scanty evidence, were merely descriptive or satirical. He was an aristocratic observer, a scorner of fools. Nature was laughing at us all; the wise man considered his fate and, by knowing it, raised himself in a measure above it. All living things pursued the greatest happiness they could see their way to; but they were marvellously short-sighted; and the business of the philosopher was to foresee and pursue the greatest happiness that was really possible. This, in so rough a world, was to be found chiefly in abstention and retrenchment. If you asked for little, it was more probable that the event would not disappoint you. It was
