"The Ego and Its Own" is a philosophical work by Max Stirner, published in 1844. It argues for individualism and self-ownership, emphasizing that the individual should prioritize their own interests and desires over societal norms and expectations. Stirner critiques established ideologies, including religion and politics, suggesting that they often suppress personal freedom. The book introduces the concept of the "Unique One," which represents the idea that each person is distinct and should embrace their individuality. Stirner's work has influenced various movements, including anarchism and existentialism, by challenging readers to question authority and assert their own identity.
