Abstract

Nietzsche characterises some influential individuals – such as Socrates and Wagner – as “decadents” because they promote life-inhibiting values that potentially undermine the flourishing of humanity. A clearly stated but less prominent example of such a decadent is Herbert Spencer. While Nietzsche’s observations concerning Spencer are far fewer than those on Socrates and Wagner, they still have considerably significance for understanding Nietzsche’s philosophy – particularly his views on morality and science – and consequently their role in his conception of decadence. This article argues that Nietzsche considers Spencer to be a decadent not just because of the latter’s advocating of a morality based on altruism, but also the projection of the decadent values of this morality as inevitable, as part of his belief in objective, scientific and sociological truths.
