There exists among men, because they are men, a solidarity through which each shares responsibility for every injustice and every wrong committed in the world, and especially for crimes that are committed in his presence or of which he cannot be ignorant. If I do not do whatever I can to prevent them, I am an accomplice in them. If I have not risked my life in order to prevent the murder of other men, if I have stood silent, I feel guilty in a sense that cannot in any adequate fashion be understood juridically, or politically, or morally ... That I am still alive after such things have been done weighs on me as a guilt that cannot be expiated.

Rohde became more and more firmly bound to the bourgeois world, its institutions and accepted opinions. … The contrast between the two natures makes Rohde and Nietzsche exemplary representatives of two distinctive worlds. In their youth they both live in the realm of boundless possibilities and feel an affinity through the exuberance of their noble aspirations. Subsequently they go in opposite directions. Nietzsche remains young, leaving concrete reality as his task assumes existential import. Rohde grows old, bourgeois, stable, and skeptical. Hence courage is a fundamental trait in Nietzsche, plaintive self-irony in Rohde. … Rohde retained the interests but not the attitudes of his youth; he looked to the world of the Greeks for the object of his contemplation rather than the norm of obligation.
