If the world were a paradise of luxury and ease, a land flowing with milk and honey, where every Jack obtained his Jill at once and without any difficulty, men would either die of boredom or hang themselves; or there would be wars, massacres, and murders; so that in the end mankind would inflict more suffering on itself than it has now to accept at the hands of Nature.

That I could clamber to the frozen moon. And draw the ladder after me.

Man is the only animal who causes pain to others with no other object than wanting to do so.

The scenes and events of long ago, and the persons who took part in them, wear a charming aspect to the eye of memory, which sees only the outlines and takes no note of disagreeable details. The present enjoys no such advantage, and so it always seems defective.

There is only one inborn erroneous notion ... that we exist in order to be happy ... So long as we persist in this inborn error ... the world seems to us full of contradictions.

No one knows what capacities for doing and suffering he has in himself, until something comes to rouse them to activity: just as in a pond of still water, lying there like a mirror, there is no sign of the roar and thunder with which it can leap from the precipice, and yet remain what it is; or again, rise high in the air as a fountain. When water is as cold as ice, you can have no idea of the latent warmth contained in it.
