He introduced the phrase in his 1949 book The Concept of Mind, in order to demonstrate the silliness of Descartes' dualist system which hypothesized that mental activity is carried on separately and without any obvious connection to physical activity. The phrase was used by Arthur Koestler for one of his book titles. ## See also[edit] * Folk science This pseudoscience-related article is a stub. You can help RationalWiki by expanding it.
