Welcome to the CTMU wiki!
The Cognitive-Theoretic Model of the Universe or CTMU (pronounced "cat-mew") is a philosophical theory of the relationship between mind and reality. Its author, Christopher Michael Langan, has been billed as "the smartest man in America", with an IQ reported by 20/20 and other media sources to have been measured at around 195. Langan created the CTMU in the mid-1980s while working as a bar bouncer on Long Island. Among his claims for the theory are that it constitutes absolute truth, provides the logical framework of a Theory of Everything, and proves the existence of God.
This site is dedicated to explaining the CTMU, analyzing arguments for and against it, and exploring its implications. It is an open wiki, which means anyone can edit it, including you! Accordingly, those who are willing and able are highly encouraged to contribute relevant content. Proponents, skeptics, and the just plain curious are equally welcome. Please keep your input civil and constructive.
