“The true basis and propaedeutic for all knowledge of human nature is the persuasion that a man's actions are, essentially and as a whole, not directed by his reason and its designs; so that no one becomes this or that because he wants to, though he want to never so much, but that his conduct proceeds from his inborn and inalterable character, is narrowly and in particulars determined by motivation, and is thus necessarily the product of these two factors.”

“Why, my man is created from the outside, that is, he is inauthentic in essence- he is always not-himself, because he is determined by form, which is born between people. His "I", therefore, is marked for him in that "interhumanity." An eternal actor, but a natural one, because his artificiality is inborn, it makes up a feature of his humanity-to be a man means to be an actor-to be a man means to pretend to be a man-to be a man means to "act like" a man while not being one deep inside-to be a man is to recite humanity.”

“man is free, in so far as he has the power of contradicting himself and his essential nature. Man is free even from his freedom; that is, he can surrender his humanity”

“Nevertheless, let no one boast. Just as every man, though he be the greatest genius, has very definite limitations in some one sphere of knowledge, and thus attests his common origin with the essentially perverse and stupid mass of mankind, so also has every man something in his nature which is positively evil. Even the best, nay the noblest, character will sometimes surprise us by isolated traits of depravity; as though it were to acknowledge his kinship with the human race, in which villainy--nay, cruelty--is to be found in that degree.”

“An educated man is not, necessarily, one who has an abundance of general or specialized knowledge. An educated man is one who has so developed the faculties of his mind that he may acquire anything he wants, or its equivalent, without violating the rights of others.”

“It is like the thirsty traveller who at first sincerely sought the water of knowledge, but who later, having found it plain perhaps, proceeded to temper his cup with the salt of doubt so that his thirst now becomes insatiable though he drinks incessantly, and that in thus drinking the water that cannot slake his thirst, he has forgotten the original and true purpose for which the water was sought.”
