This, in brief, is Nietzsche's doctrine applied to the organic and inorganic world. In its application to the ideological world, the reasoning is not changed. In ideas Nietzsche finds this same will to power. But in them it is the reflection of the principle inherent in the material world. There is no will inherent in ideas. This assumption of a reflected will to power in the ideological world is one of Nietzsche's most important concepts, for it makes all ideas the outgrowth of ourselves, and therefore dependent on natural laws. It does away with the conception of supernatural power and with the old philosophical belief that ideas are superior forces to those of the organic and inorganic world. Nietzsche once and for all disposes of the theory that there is anything more powerful than force, and by thus doing away with this belief, he rationalises all ideas and puts thought on a tangible and stable basis. In the opening section of the present book where he applies the will to power to scientific research, the whole of this new theory is made clear, and I advise the student to read well this section, for I have been unable to present as clear and complete an expositional statement of it in Nietzsche's own words as I would have liked to do, owing to the close and interrelated manner in which these notes were written. Volume II of "The Will to Power" is in two books. The first is called "The Principles of a New Valuation"; the second, "Discipline and Breeding." The first book is divided into four sections--"The Will to Power in Science," "The Will to Power in Nature," "The Will to Power as Exemplified in Society and in the Individual" and "The Will to Power in Art." The second book has three divisions--"The Order of Rank," "Dionysus" and "Eternal Recurrence." Of the first section of Book One, "The Will to Power in Science," I have already spoken. In this section Nietzsche shows how arbitrary a thing science is, and how closely related are its conclusions to the instinct of the scientists, namely: the instinct of the will to power. Scientists, he holds, are confronted by the necessity of translating all phenomena into terms compatible with the struggle for persistence and maintenance. A fact in nature unaccounted for is a danger, an obstacle to the complete mastery of natural conditions. Consequently the scientist, directed and influenced by his will to power, invents explanations which will bring all facts under his jurisdiction and control, and will thereby increase his feeling of power. As a result, the great facts of life are looked upon as of secondary importance to their explanations, and science becomes, not an intelligent search for knowledge, but a system of interpretations tending to increase the feeling of mastery in the men directly connected with it. Thus the law of the will to power, as manifest in the organic and inorganic world, becomes the dominating instinct in the ideological world as well.
