方法序説
The book is Nietzsche's first in the aphoristic style that would come to dominate his writings, discussing a variety of concepts in short paragraphs or sayings. Reflecting an admiration of Voltaire as a free thinker, but also a break in his friendship with composer Richard Wagner two years earlier, Nietzsche dedicated the original 1878 edition of "Human, All Too Human" 'to the memory of Voltaire on the celebration of the anniversary of his death, May 30, 1778'. Instead of a preface, the first part originally included a quotation from Descartes's "Discourse on the Method". Nietzsche later republished all three parts as a two-volume edition in 1886, adding a preface to each volume, and removing the Descartes quotation as well as the dedication to Voltaire.
