Solipsism
Mere denial of material existence, in itself, does not necessarily constitute solipsism.
Philosophers generally try to build knowledge on more than an inference or analogy. Well-known frameworks such as Descartes' epistemological enterprise brought to popularity the idea that all certain knowledge may go no further than "I think; therefore I exist."However, Descartes' view does not provide any details about the nature of the "I" that has been proven to exist.
The theory of solipsism also merits close examination because it relates to three widely held philosophical presuppositions, each itself fundamental and wide-ranging in importance.
One's most certain knowledge is the content of one's own mind—my thoughts, experiences, affects, etc.
There is no conceptual or logically necessary link between mental and physical—between, for example, the occurrence of certain conscious experience or mental states and the "possession" and behavioral dispositions of a "body" of a particular kind.
The experience of a given person is necessarily private to that person.
