"If the inner psychic ground of our individual appearance were not always the same, there could be no science of psychology, which qua science relies on a psychic “inside we are all alike,” just as the science of physiology and medicine relies on the sameness of our inner organs.

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”
