Some people do not become thinkers simply because their memories are too good.

Where the good begins.- Where the poor power of the eye can no longer see the evil impulse as such because it has become too subtle, man posits the realm of goodness; and the feeling that we have now entered the realm of goodness excites all those impulses which had been threatened and limited by the evil impulses, like the feeling of security, of comfort, of benevolence. Hence, the duller the eye, the more extensive the good. Hence the eternal cheerfulness of the common people and of children. Hence the gloominess and grief - akin to a bad conscience - of the great thinkers.

People live for the morrow, because the day-after-to-morrow is doubtful.

He who has a why to live can bear almost any how.

Experience, as a desire for experience, does not come off. We must not study ourselves while having an experience.

Be generous in nature and thought; for this wins respect and gives confidence and power.

There is always some madness in love. But there is also always some reason in madness.
