All idealism is falsehood in the face of necessity

Necessity is not an established fact, but an interpretation.

History is nothing more than the belief in the senses, the belief in falsehood.

In order to acquire intellect one must need it. One loses it when it is no longer necessary.

One hears but one does not seek; one takes -- one does not ask who gives; a thought flashes up like lightning, it comes of necessity and unfalteringly formed.

No small art is it to sleep: it is necessary for that purpose to keep awake all day.
