On the Genealogy of Morality: A Polemic (German: Zur Genealogie der Moral: Eine Streitschrift) is an 1887 book by German philosopher Friedrich Nietzsche.
It consists of a preface and three interrelated essays that expand and follow through on concepts Nietzsche sketched out in Beyond Good and Evil (1886).
He had previously employed this expression to represent the lion, an image that is central to his philosophy and made its first appearance in Thus Spoke Zarathustra.
Beyond the metaphorical lion, Nietzsche expressively associates the "blond beast" with the pre-Aryan race of Celts and Gaels which he states were all fair skinned and fair-haired and constituted the collective aristocracy of the time.
In the "Second Treatise" Nietzsche advances his thesis that the origin of the institution of punishment is in a straightforward (pre-moral) creditor/debtor relationship.
Man relies on the apparatus of forgetfulness [which has been "bred" into him] in order not to become bogged down in the past.
This control over the future allows a "morality of custom" to establish.
(Such morality is sharply differentiated from Christian or other "ascetic" moralities.) The product of this morality, the autonomous individual, comes to see that he may inflict harm on those who break their promises to him.
Only the weak need the illusion of the subject (or soul) to hold their actions together as a unity.
But they have no right to make the bird of prey accountable for being a bird of prey.
