One of the world's most important philosophers of mind and language, John Searle (b. 1932) is direct, combative, and intellectually ambitious. His philosophy has made fundamental and lasting contributions to how we think about speech, consciousness, knowledge, truth, and the nature of social reality. Here, with remarkable clarity, a leading authority introduces students and generalists to those contributions. Nick Fotion explains Searle's ideas in full, while also testing and exploring their implications. He first takes up Searle's philosophy of language, examining how Searle treats speech acts and thinks about the metaphorical use of language. Next, the book sketches Searle's philosophy of mind, including his claims for intentionality and for the centrality of consciousness. This discussion highlights Searle's argument that the mind possesses a subjective character that materialist explanations (including behaviorism and strong artificial intelligence) cannot contain. The author goes on to look at Searle's later writings on the construction of social reality - work that mounts a sophisticated but plainly stated case against deconstructionist, skeptical, and relativistic accounts. Concluding with general reflections on Searle's position vis-a-vis ontology and epistemology, this book is the first to assess and identify common themes and approaches in the whole range of his extensive thought. In doing so, it presents Searle's extremely influential work for the first time as a coherent philosophy.
