Solipsism
Solipsism is the radical philosophical idea that only one’s mind is sure to exist. This perspective casts extreme doubt on the reality of anything outside personal consciousness, including other people and the external world itself. Solipsism challenges the very foundation of shared reality, raising questions about whether anything beyond subjective experience can be truly known. This viewpoint has been explored in literature, film, and popular culture, often as a tool to provoke existential reflection and skepticism.
