The style of "The Genealogy of Morals" is less aphoristic than any of the books which immediately preceded or followed it. Few new doctrines are propounded in it; and since it was for the most part an analytic commentary on what had gone before, its expositional needs were best met by Nietzsche's earlier style of writing. I have spoken before of the desultory and sporadic manner in which Nietzsche was necessitated to present his philosophy. Nowhere is his method of work better exemplified than in this new work. Nearly every one of his books overlaps another. Propositions are sketchily stated in one essay, which receive elucidation only in future volumes. "Beyond Good and Evil" was a commentary on "Thus Spake Zarathustra"; "The Genealogy of Morals" is a commentary on the newly propounded theses in "Beyond Good and Evil" and is in addition an elaboration of many of the ideas which took birth as far back as "Human, All-Too-Human." Out of "The Genealogy of Morals" in turn grew "The Antichrist" which dealt specifically with the theological phase of the former's discussion of general morals. And all of these books were but preparations for "The Will to Power." For this reason it is difficult to acquire a complete understanding of Nietzsche's philosophy unless one follows it consecutively and chronologically. The book at present under discussion is a most valuable one from an academic standpoint, for, while it may not set forth any new and important doctrines, it goes deep into the origins and history of moral concepts, and explains many of the important conclusions in Nietzsche's moral code. It brings more and more into prominence the main pillars of his ethical system and explains at length the steps in the syllogism which led to his doctrine of master-morality. It ascertains the origin of the concept of sin, and describes the racial deterioration which has followed in the train of Christian ideals.
