The Genealogy of Morals is a philosophical work by Friedrich Nietzsche, published in 1887 as three essays. It inquires into the origins of moral concepts such as good and evil, guilt, and the ascetic ideal, and examines how moral judgments shape human psychology. It is worth reading for its probing critique of conventional moral values.
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.
