"It is, I think, safe to say that nothing was more alien to the minds of the scientists, who brought about the most radical and most rapid revolutionary process the world has ever seen, than any will to power. Nothing was more remote than any wish to ‘conquer space’ and to go to the moon. It was indeed their search for ‘true reality’ that led them to lose confidence in appearances, in the phenomena as they reveal themselves of their own accord to human sense and reason.

Hatred and love belong together, and they are both destructive; you can afford them only in private and, as a people, only so long as you are not free”
