“Human All-Too-Human” is the name of book, that was Nietzsche's first work in the aphoristic style that became dominant in his writings. The work marked for Nietzsche a new "positivism" and skepticism with which he challenged his previous metaphysical and psychological assumptions. “Human, All Too Human” is a collection of 638 aphorisms divided into nine categories in which Nietzsche reveals his observations of human nature and exposes common misunderstandings humans have regarding philosophy, religion, art, morality, society, relationships, men and women. This work remains one of the fundamental works for an understanding of his thought, so it's absolutely must-read for every educated person.
