Nietzsche argues in the Second Essay of the Genealogy against Eugen Dühring (1833–1901)—the German philosopher and political economist whom Nietzsche read closely 1 —that the origin of justice does not lie in ressentiment. On the other hand, Robert Solomon accuses Nietzsche of being too one-sided and critical of ressentiment, thus failing to see that ressentiment ‘is the gateway to a sense of justice—or, more accurately, a sense of injustice—from which our sense of justice is derived’ (Solomon, p. 116).
