Truth is no harlot who throws her arms round the neck of him who does not desire her; on the contrary, she is so coy a beauty that even the man who sacrifices everything to her can still not be certain of her favors.
Suffering by nature or chance never seems so painful as suffering inflicted on us by the arbitrary will of another.
Pleasure is never as pleasant as we expected it to be and pain is always more painful. The pain in the world always outweighs the pleasure. If you don't believe it, compare the respective feelings of two animals, one of which is eating the other.
Patriotism, when it wants to make itself felt in the domain of learning, is a dirty fellow who should be thrown out of doors.
It is only a man's own fundamental thoughts that have truth and life in them. For it is these that he really and completely understands. To read the thoughts of others is like taking the remains of someone else's meal, like putting on the discarded clothes of a stranger.
There is no doubt that life is given us, not to be enjoyed, but to be overcome; to be got over.
