Nietzschean affirmation

Nietzschean affirmation (German: Bejahung) is a concept that scholars have identified in the philosophy of Friedrich Nietzsche. An example used to describe the concept is a fragment in Nietzsche's The Will to Power:

Suppose that we said yes to a single moment, then we have not only said yes to ourselves, but to the whole of existence. For nothing stands alone, either in ourselves or in things; and if our soul did but once vibrate and resound with a chord of happiness, then all of eternity was necessary to bring forth this one occurrence—and in this single moment when we said yes, all of eternity was embraced, redeemed, justified and affirmed.

— Nietzsche, Friedrich, The Will to Power: Selections from the Notebooks of the 1880s (translated by R. Kevin Hill and Michael A. Scarpitti). Penguin Books, 2017, p. 566

Nietzsche’s affirmative philosophy, as expressed in his parable about eternal recurrence, places his conception of amor fati and his instruction towards the positive embrace of the will to power in a cosmically expanded and universally determined context. Only the embrace of what is and will be, according to the will and its position within natural accident, constitutes freedom (or its nameless equivalent) in Nietzsche’s vision. The ethical injunction about what should be is dismissed by this parable.
