Master–slave morality is a central theme of Friedrich Nietzsche's works, in particular the first essay of On the Genealogy of Morality. Nietzsche argued that there were two fundamental types of morality: 'Master morality' and 'slave morality'. Slave morality values things like kindness, humility and sympathy, while master morality values pride, strength, and nobility. Master morality weighs actions on a scale of good or bad consequences unlike slave morality which weighs actions on a scale of good or evil intentions. For Nietzsche, a particular morality is inseparable from the formation of a particular culture. This means that its language, codes and practices, narratives, and institutions are informed by the struggle between these two types of moral valuation.
