Max Stirner
The Ego and Its Own
Max Stirner's 1844 critique of fixed ideas — the state, morality, property, religion — as a form of alienation is a foundational text of egoist anarchism, and its influence on later existentialism and nihilism justifies the philosophy-adjacent genres over fiction. The book's dense, provocative deconstruction of authority and convention sets a dark, intellectual, and thought-provoking tone; the content is dense and challenging, which warrants the dense/complex tags.
