Nietzsche" s investigations into the problem of the birth (Geburt) or origin (Herkunft) of concepts — the problem of genealogy — did not begin with On the Genealogy of Morals (1887). Nietzsche had always sought to understand the genesis of cultural facts. Thus, The Birth of Tragedy (1872) is a history of consciousness, a kind of conversion rite designed to illuminate and reawaken the deep origin of Western civilization. Additional evidence for Nietzsche" s enduring concern appears in Human, All Too Human (1878–1880), or Daybreak (1882) and other writings, published and unpublished.
