Notes from Underground by Fyodor Dostoevsky is a seminal work of existential literature. The novel is narrated by a bitter, isolated former civil servant who delivers a dark and introspective monologue criticizing rationalism, utopianism, and human nature. His rambling reflections expose inner conflict, pride, self-loathing, and resistance to societal norms. The book’s psychological depth and philosophical insights mark it as a forerunner of modernist and existentialist thought.
