In 1887, with the view of amplifying and completing certain new doctrines which he had merely sketched in Beyond Good and Evil, Nietzsche published On The Genealogy of Morals. The preface and three essays trace episodes in the evolution of moral concepts with the intent to undermine moral prejudices. 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.
