This is a translation of both volumes of Nietzsche's Human, All Too Human. The first volume appeared in 1878, just before Nietzsche abandoned his academic life. In 1886 it was republished, incorporating in a second volume two books of aphorisms which Nietzsche had published in the meantime. Subtitled 'A Book for Free Spirits', Human, All Too Human marked for Nietzsche a new 'positivism' and scepticism with which he challenged his previous metaphysical and psychological assumptions. Nearly all the themes of his later work are displayed here with characteristic perceptiveness and honesty, it remains one of the works fundamental for an understanding of his thought.
