In epistemology, epistemological solipsism is the claim that one can only be sure of the existence of one's mind. The existence of other minds and the external world is not necessarily rejected but one can not be sure of its existence.Sami Pihlström, Why Solipsism Matters, Bloomsbury Publishing, 2020, ch. 2: "Metaphysical and Skeptical Solipsism", subch.: "Classical Metaphysical and Epistemological Solipsism—the Cartesian Legacy."
