Perhaps I know best why it is man alone who laughs; he alone suffers so deeply that he had to invent laughter.

Nobody is more inferior than those who insists on being equal.

No one can draw more out of things, books included, than he already knows. A man has no ears for that to which experience has given him no access.

Shared joys make a friend, not shared sufferings.

There are slavish souls who carry their appreciation of favors done them so far that they strangle themselves with the rope of gratitude.

All truly great thoughts are conceived by walking.
