French philosopher René Descartes (1596-1650) can be blamed for the idea that if one whittles away beliefs about which one cannot be certain, one will eventually land at the existence of the self as a singular certainty; however, he cannot be blamed for either the word solipsism or the theory it refers to. (Descartes avoided falling into solipsism by positing that ideas known with the same clarity as the existence of the self is known must also be true.) Philosophical application of the word likely owes something to the French translation of a satiric work written by Venetian scholar Giulio Clemente Scotti in 1645 called Monarchia Solipsorum —in French, La Monarchie des Solipses. The pertinent term is a composite of the Latin solus ("alone") and ipse ("self").
