Nietzsche

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

Friedrich Wilhelm Nietzsche was a German philosopher, cultural critic and philologist whose work has exerted a profound influence on modern intellectual history. He began his career as a classical philologist before turning to philosophy.
