What is solipsism definition?

Solipsism is the philosophical idea that only one's own mind is sure to exist. It is a theory that posits that the self and consciousness are the only absolute thing that one can be sure of. It maintains that everything else in the external world, including other people, is uncertain and may not be real. Solipsism is often associated with skepticism and has been a subject of skepticism and debate among philosophers for centuries. Some argue that solipsism is an extreme and misguided philosophy, while others view it as a valid and thought-provoking perspective on reality.
