Wikipedia
Experientialism is the philosophical theory that experience is the source of knowledge. It was originally formulated by George Lakoff and Mark Johnson and its first widely known formulation is to be found in the book Metaphors We Live By.
In Women, Fire and Dangerous Things, Lakoff has expanded on the foundation of experientialism by his research into the nature of categories.
