Such, sketched as briefly as possible, is the physiological background on which we must set his work.

The greater part of that work (which fills seventeen volumes in the English translation) is made up of short numbered paragraphs, arranged under general headings. The lectures and poems are, indeed, the only exceptions, for though The Birth of Tragedy, and the essays called Thoughts out of Season, are less disintegrated than later books, we can perceive, in their numbered sections, the promise of sections shorter and continually shortening to the brief “Maxims and Missiles” at the beginning of The Twilight of the Idols. Even Thus Spake Zarathustra was built in a similar manner, though disguised by the rush of prophecy and a more definite general scheme. Nietzsche allowed such constructive power as he had to atrophy. He was never a systematic thinker, but, because his paragraphs are not such separate and individual observations like those of Chamfort or Vauvenargues; because they were often written in swift succession, one after another, there is a dangerous possibility that in reading them we may feel we are reading notes for a book which the author has not troubled to piece together into the superficial form to which we are accustomed. We may resent this, but we are more likely to grow weary of the constant change of subject, of the staccato iteration of ideas without prologues or epilogues to awaken slowly and lull again to repose our sluggish brains. It is well to remember that we have learnt to read too fast, and that Nietzsche foresaw our discomfort. “He that writeth in blood doth not want to be read but learnt by heart.... It is no easy task to understand unfamiliar blood. I hate the reading idlers.” We cease to feel the superficial confusion and inconsistency of those ten thousand paragraphs when we become better aware of the half-dozen ideas that were the parents of that numerous family. We are then able to trace a paragraph’s pedigree, and to place it in a larger scheme than that of the volume in which it happens to be printed. No reader of Nietzsche can have failed to notice that his books, different in detail, different in application, yet often seem coincident with each other. Nor is this due to chance repetitions that would betray an uncritical improvisation. It is an accurate indication of Nietzsche’s habit of mind. His books were gleanings, and, after his mature work began, they were gleanings from fields almost uniformly sown. The seasons varied and the sower’s arm was irregular in its swing, but the harvest was always from a field that had been fertilised by a fairly uniform mixture of ideas. The ideas of the pragmatic nature of truth, of Eternal Recurrence, of the Will to Power, of the Superman, and of master and servant morality, yield in book after book a new crop of lesser ideas, applied, amplified, restricted or illustrated in psychological observation. For this reason I do not intend, in what can but be a short essay, any detailed criticism of Nietzsche’s books, but rather to note the results of such criticism. The reading of his books, unless it be impatient, careless, and unworthy, is a process of discovering what were those half-dozen ideas that separated Nietzsche from the thinkers of his time, stimulated his brain until at last it broke, and during many years kept him in the lonely joyful ecstasy of continual exploration.

“The first adherents of a creed do not prove anything against it,” but they often so obscure it as to postpone its eventual utility. Some of the half-dozen ideas I have mentioned have been so often caricatured that it is extremely difficult to recognise them without the exaggeration with which we have been made familiar. It is not easy to state another man’s ideas. To fail is to do him an injury. To succeed is not unlike taking the words out of his mouth, which is rude. But I am neither a translator of Nietzsche nor an opponent. I wish to understand, not to persuade. And, for understanding, such statement is desirable.

Nietzsche neither escapes nor attempts to escape the contradictions in the form of thought that make logic and life battledores to toss laughter at each other like a shuttlecock. He is a determinist and yet gives advice, the giving of which presupposes a belief in free will and a possible choice. He seeks to influence others, and, in his manner at least, forgets that the logical determinist should only allow himself to say: “Circumstances compel me to make certain statements, which, in the form of circumstances, may or may not share in the sum of circumstances that compel you to actions and thoughts which in their totality I cannot conceive.” That is not the view of his own activity which dictates the eager vivid combination of argument and incantation that makes Nietzsche’s books. He is free, in that he has the illusion of freedom. The illusion of freedom is one of the determining circumstances. Its effect is to make it unnecessary to remember in practice that circumstances determine.

We need not therefore hesitate over the inconsistency apparent between some of Nietzsche’s ideas. We do better to notice it as characteristic of his thought, and simply to state his ideas, remembering, if we will, that they belong to different circles of consciousness; some to that wider circle that includes the universe and with it determinism, and some to that smaller circle, concentric with the first, and including only the area of practical activity. Let us be determinists first and examine the Nietzschean universe.

The idea of Eternal Recurrence seems to have had for Nietzsche something of the hypnotic character of those ideas that made Poe write of his Eureka: “What I here propound is true: therefore it cannot die;—or if by any means it be now trodden down so that it die, it will ‘rise again to the Life Everlasting.’” Indeed the idea itself is not unlike that of Poe, who, untrained alike in philology and philosophy, expressed himself in a manner that would have given Nietzsche exquisite pain:

“Guiding our imagination by that omniprevalent law of laws, the law of periodicity, we are not, indeed, more than justified in entertaining a belief—let us say, rather, indulging a hope—that the processes we have ventured to contemplate will be renewed for ever, and for ever, and for ever; a novel Universe swelling into existence, and then subsiding into nothingness, at every throb of the Heart Divine?” (Poe’s Eureka.)

Now Nietzsche would not have spoken of a “Heart Divine,” even explaining, as Poe did, that this heart was our own; but he did contemplate a perpetually self-renewing Universe. Only—and herein lay the importance of his idea to himself—he saw it renewing itself in every detail, in every minutest action of the minutest of its individual parts, at every moment of its cycle. Every moment of the future being dependent upon and involved in the present moment, sooner or later in the course of time there would come a moment similar in every detail to a moment that had already existed, thus guaranteeing a similar series of moments till it should recur, and so on. He said:

“If the Universe may be conceived as a definite quantity of energy, as a definite number of centres of energy—and every other concept remains indefinite and therefore useless—it follows therefrom that the Universe must go through a calculable number of combinations in the great game of chance which constitutes its existence. In infinity, at some moment or other, every possible combination must once have been realised; not only this, but it must have been realised an infinite number of times. And inasmuch as between every one of these combinations and its next recurrence, every other possible combination would necessarily have been undergone, and since every one of these combinations would determine the whole series in the same order, a circular movement of absolutely identical series is thus demonstrated; the Universe is thus shown to be a circular movement which has already repeated itself an infinite number of times, and which plays its game for all eternity.”

Nietzsche, hypnotised by this idea, believed it new, but there is a clear suggestion of it in the third book of Lucretius’ poem:
