On the Genealogy of Morals

Three essays on where moral categories came from: master and slave morality, the invention of guilt out of debt, and the ascetic ideal as a will to nothing rather than an absence of will.

Why it’s on the list: Named in the “how the world really works” thread. The founding demonstration of genealogy as a method — asking not whether a value is true but who needed it and what it did for them.

Where I saw it: In Kyle’s “Books To Read” Apple Note, recovered from the reply thread to @SpencrGreenberg asking “What non-fiction book taught you the most about how the world (or how humanity or society) really works?” (June 5, 2025). The full recovered list lives on A question for you — What non-fiction… (tweet).
