Sách nói: Human, All Too Human: A Book For Free Spirits, Part I

"Human, all-too-Human, is the monument of a crisis. It is entitled: 'A book for free spirits,' and almost every line in it represents a victory—in its pages I freed myself from everything foreign to my real nature. Idealism is foreign to me: the title says, 'Where you see ideal things, I see things which are only—human alas! all-too-human!' I know man better—the term 'free spirit' must here be understood in no other sense than this: a freed man, who has once more taken possession of himself." (Nietzsche; Ecce Homo, p. 75.)
