Did You Know?
Fans of René Descartes credit the French philosopher with introducing solipsism as a major problem of modern philosophy, but the word solipsism most likely sprang from a French satire written by Giulio Clemente Scotti in 1652 called La Monarchie des Solipses. The term wasn't used in English until the late 19th century, when solipsism, a composite of the Latin solus ("alone") and ipse ("self"), was applied purely in the philosophical sense. Recently the word has taken on another, more general sense, suggesting an ego-driven selfishness or self-indulgence.
