"Man... knows only when he is satisfied and when he suffers, and only his sufferings and his satisfactions instruct him concerning himself, teach him what to seek and what to avoid. For the rest, man is a confused creature; he knows not whence he comes or whither he goes, he knows little of the world, and above all, he knows little of himself."
"Whenever I hear people talking about liberal ideas, I am always astounded that men should love to fool themselves with empty sounds. An idea should never be liberal; it must be vigorous, positive, and without loose ends so that it may fulfill its divine mission and be productive. The proper place for liberality is in the realm of the emotions."
