Before leaving Part I., with which it would be impossible to deal in full, a word or two ought to be said in regard to Nietzsche's views concerning the belief in "cause and effect." In the Genealogy of Morals (1st Essay, Aph. 13), we have already read a forecast of our author's more elaborate opinions on this question, and the aphorism in question might be read with advantage in conjunction with the discussion on the subject found in this book (Aphs. 545-555).
The whole of Nietzsche's criticism, however, resolves itself into this, that the doctrine of causality begins with an unnecessary duplication of all that happens. Language, and its origin among a people uneducated in thoughts and concepts, is at the root of this scientific superstition, and Nietzsche traces its evolution from the primeval and savage desire always to find a "doer" behind every deed: to find some one who is responsible and who, being known, thus modifies the unfamiliarity of the deed which requires explaining. "The so-called instinct of causality [of which Kant speaks with so much assurance] is nothing more than the fear of the unfamiliar."
In Aph. 585 (A), we have a very coherent and therefore valuable exposition of much that may still seem obscure in Nietzsche's standpoint, and we might almost regard this aphorism as the key to the epistemology of the Will to Power. When we find the "will to truth" defined merely as "the longing for a stable world," we are in possession of the very leitmotiv of Nietzsche's thought throughout Part I., and most of what follows is clearly but an elaboration of this thought.
In Part II. Nietzsche reveals himself as utterly opposed to all mechanistic and materialistic interpretations of the Universe. He exalts the spirit and repudiates the idea that mere pressure from without—naked environment—is to be held responsible (and often guilty!) for all that materialistic science would lay at its door. Darwin again comes in for a good deal of sharp criticism; and, to those who are familiar with the nature of Nietzsche's disagreement with this naturalist, such aphorisms as Nos. 643, 647, 649, 651, 684, 685, will be of special interest. There is one question of great moment, which all Nietzsche's perfectly sincere and profoundly serious deprecation of the Darwinian standpoint ought to bring home to all Englishmen who have perhaps too eagerly endorsed the conclusions of their own British school of organic evolution, and that is, to what extent were Malthus, and afterwards his disciple Darwin, perhaps influenced in their analysis of nature by preconceived notions drawn from the state of high pressure which prevailed in the thickly-populated and industrial country in which they both lived?
It is difficult to defend Darwin from the fundamental attack which Nietzsche directs at the very root of his teaching, and which turns upon the question of the motive of all Life's struggle. To assume that the motive is always a "struggle for existence" presupposes the constant presence of two conditions—want and over-population,—an assumption which is absolutely non-proven, and it likewise lends a peculiarly ignoble and cowardly colouring to the whole of organic life, which not only remains unsubstantiated in fact, but which the struggle for power completely escapes. In Part III., which, throughout, is pretty plain sailing, Aphorism 786 contains perhaps the most important statements. Here morality is shown to be merely an instrument, but this time it is the instrument of the gregarious will to power. In the last paragraph of this aphorism Nietzsche shows himself quite antagonistic to Determinism, because of its intimate relation to, and its origin in, a mechanistic interpretation of the Universe. But we should always remember that, inasmuch as Nietzsche would distribute beliefs, just as others distribute bounties—that is to say, according to the needs of those whom he has in view, we must never take for granted that a belief which he deprecates for one class of man ought necessarily, according to him, to be denied another class.
Hard as it undoubtedly is to bear this in mind, we should remember that his appeal is almost without interruption made to higher men, and that doctrines and creeds which he condemns for them he would necessarily exalt in the case of people who were differently situated and otherwise constituted. Christianity is a case in point (see Will to Power, vol. i. Aph. 132).
We now come to Part IV., which is possibly the most important part of all, seeing that it treats of those questions which may be regarded as Nietzsche's most constant concern from the time when he wrote his first book.
The world as we now see and know it, with all that it contains which is beautiful, indifferent, or ugly, from a human standpoint, is, according to Nietzsche, the creation of our own valuing minds. Perhaps only a few people have had a hand in shaping this world of values. Maybe their number could be counted on the fingers of two hands; but still, what Nietzsche insists upon is, that it is human in its origin. Our whole outlook, everything that gives us joy or pain, must at one time or other have been valued for us, and in persisting in these valuations we, as the acclimatised herd, are indebted to our artists, to our higher men, to all those in history, who at some time or other have dared to stand up and to declare emphatically that this was ugly and that that was beautiful, and to fight, and if necessary to die, for their opinion.
Religion, morality, and philosophy, while they all aim at so-called universal Truth, tend to depreciate the value of life in the eyes of exceptional men. Though they establish the "beautiful" for the general stock, and in that way enhance the value of life for that stock, they contradict higher men's values, and, by so doing, destroy their innocent faith in the world. For the problem here is not, what value is true?—but, what value is most conducive to the highest form of human life on earth?
Nietzsche would fain throw all the burden of valuing upon the Dionysian artist him who speaks about this world out of the love and plenitude of power that is in his own breast, him who, from the very health that is within him, cannot look out upon life without transfiguring it, hallowing it, blessing it, and making it appear better, bigger, and more beautiful. And, in this view, Nietzsche is quite consistent; for, if we must accept his conclusion that our values are determined for us by our higher men, then it becomes of the highest importance that these valuers should be so constituted that their values may be a boon and not a bane to the rest of humanity.
