George Bealer

George Bealer (1944–January 2025) was an American philosopher and Professor Emeritus of Philosophy at Yale University. He is known for his works on philosophy of mind, philosophy of language, epistemology, and logic. Bealer is particularly well known for his work on the nature of the a priori and philosophical intuitions, where he defended the reliability of intuitions as a source of evidence in philosophical inquiry.

He was the author of Quality and Concept (Clarendon Press, 1983), which developed a unified theory of properties, relations, and propositions. He also co-edited The Waning of Materialism (2010) with Robert C. Koons, a volume addressing contemporary philosophical debates on the nature of mind and materialism.

Bealer held academic positions at the University of Texas at Austin, the University of Colorado Boulder, and Reed College before joining Yale University. He completed his PhD at the University of California, Berkeley.
