Underused Word of the Day

cosmothetic [kahz-moh-thet-ik]- an adjective meaning 'something that assumes there is an external world'. It is used about a theory of perception that posits the existence of an external world but denies that we have any evidence of it or knowledge about it. Perhaps useful for describing such statements such as "I know there are people who put mayonnaise on hot dogs, but I've never met one myself." From Greek words meaning 'world' plus 'positing'.
