To point, as many have done, to the proximity of all Nietzsche's autumn work of the year 1888 to his breakdown at the beginning of 1889, and to argue that in all its main features it foretells the catastrophe that is imminent, seems a little too plausible, a little too obvious and simple to require refutation. That Nietzsche really was in a state which in medicine is known as _euphoria_--that is to say, that state of highest well-being and capacity which often precedes a complete breakdown, cannot, I suppose, be questioned; for his style, his penetrating vision, and his vigour, reach their zenith in the works written in this autumn of 1888; but the contention that the matter, the substance, of these works reveals any signs whatsoever of waning mental health, or, as a certain French biographer has it, of an inability to "hold himself and his judgments in check," is best contradicted by the internal evidence itself. To take just a few examples at random, examine the cold and calculating tone of self-analysis in Chapter I. of the present work; consider the reserve and the restraint with which the idea in Aphorism 7 of that chapter is worked out,--not to speak of the restraint and self-mastery in the idea itself, namely:-- "To be one's enemy's equal--this is the first condition of an honourable duel. Where one despises one cannot wage war. Where one commands, where one sees something beneath one, one ought not to wage war. My war tactics can be reduced to four principles: First, I attack only things that are triumphant--if necessary I wait until they become triumphant. Secondly, I attack only those things against which I find no allies, against which I stand alone--against which I compromise nobody but myself.... Thirdly, I never make personal attacks--I use a personality merely as a magnifying-glass, by means of which I render a general, but elusive and scarcely noticeable evil, more apparent.... Fourthly, I attack only those things from which all personal differences are excluded, in which any such thing as a background of disagreeable experiences is lacking." And now notice the gentleness with which, in Chapter II., Wagner--the supposed mortal enemy, the supposed envied rival to Nietzsche--is treated. Are these the words and the thoughts of a man who Has lost, or who is losing control?
