In 1887, with the view of amplifying and completing certain new doctrines which he had merely sketched in Beyond Good and Evil (see especially Aphorism 260), Nietzsche published The Genealogy of Morals. This work is perhaps the least aphoristic, in form, of all Nietzsche's productions. For analytical power, more especially in those parts where Nietzsche examines the ascetic ideal, The Genealogy of Morals is unequalled by any other of his works; and, in the light which it throws upon the attitude of the ecclesiast to the man of resentment and misfortune, it is one of the most valuable contributions to sacerdotal psychology. In Beyond Good and Evil, Nietzsche accuses past philosophers of lacking critical sense and blindly accepting dogmatic premises in their consideration of morality. Specifically, he accuses them of founding grand metaphysical systems upon the faith that the good man is the opposite of the evil man, rather than just a different expression of the same basic impulses that find more direct expression in the evil man. The work moves into the realm "beyond good and evil" in the sense of leaving behind the traditional morality which Nietzsche subjects to a destructive critique in favour of what he regards as an affirmative approach that fearlessly confronts the perspectival nature of knowledge and the perilous condition of the modern individual. Of the four "late-period" writings of Nietzsche, Beyond Good and Evil most closely resembles the aphoristic style of his middle period. In it he exposes the deficiencies of those usually called "philosophers" and identifies the qualities of the "new philosophers" imagination, self-assertion, danger, originality, and the "creation of values." He then contests some of the key presuppositions of the old philosophic tradition like "self-consciousness," "knowledge," "truth," and "free will," explaining them as inventions of the moral consciousness. In their place, he offers the "will to power" as an explanation of all behavior; this ties into his "perspective of life," which he regards as "beyond good and evil," denying a universal morality for all human beings. Religion and the master and slave moralities feature prominently as Nietzsche re-evaluates deeply held humanistic beliefs, portraying even domination, appropriation and injury to the weak as not universally objectionable. Friedrich Wilhelm Nietzsche (15 October 1844 - 25 August 1900) was a German philosopher, cultural critic, poet, philologist, and Latin and Greek scholar whose work has exerted a profound influence on Western philosophy and modern intellectual history. He began his career as a classical philologist before turning to philosophy.
