Eternal Recurrence, Responsibility, Privilege

Among the events in one's past are one's actions, i. e. events which one initiated.  Hence, the affirmation of one's entire past entails that of one's past actions.  Now, to affirm the eternal recurrence of a past action is to affirm that 'one would do it again the same way'.  But, to affirm that one would do something again the same way is to take responsibility for it.  Thus, the affirmation of Eternal Recurrence entails the assumption of responsibility for each of one's past actions, which may be why Nietzsche characterizes Responsibility as a "privilege", in the Genealogy of Morals, II, 3.
