In questions of science, the authority of a thousand is not worth the humble reasoning of a single individual.
The most complete authority is the kind that penetrates the inner man, and influences his will as much as his actions.[L’autorité la plus absolue est celle qui pénètre jusqu’à l’intérieur de l’homme, et ne s’exerce pas moins sur la volonté que sur les actions.]
Men use thought only as authority for their injustice, and employ speech only to conceal their thoughts.
I do not believe in immortality of the individual, and I consider ethics to be an exclusively human concern with no superhuman authority behind it.
For in that sphere, the exercise of authority consists precisely in administration.[Denn Herrschaft ist im Alltag primär: Verwaltung.]
