English speakers started using the words solipsism and solipsist to describe the theory and the accompanying lifestyle that go along with people who believe that their sole existence is all that matters above all else. We derived the word from the Latin solus, which represents the self. This philosophical theory has been hotly debated since the theory of solipsism entered our awareness in 1836.
