Koons has been involved in debates over issues of academic freedom and has advocated for college exit exams as he believes the measures used currently don't measure how well students learn. He led an effort at UT to create a concentration in Western Civilization and American Institutions. The goal of the program was to promote the study of the "Great Books" of the Western tradition, especially the American founding. Koons stated that the program transcended political differences.
Koons is co-editor, with George Bealer, of The Waning of Materialism: New Essays in the Philosophy of Mind (Oxford University Press, 2010), a collection of articles by leading analytic philosophers critical of physicalism and materialism. He is engaged in contributing to contemporary metaphysics and the philosophy of religion, including a forthcoming textbook, Metaphysics: The Fundamentals, (with co-author Timothy Pickavance; Blackwell-Wiley, to appear January 2015).
