"Glasgow’s book is a lucid, measured, and extremely valuable contribution to current discourse about race. It will go into the canon of serious analysis of race which has to be consulted by careful scholars." - Naomi Zack, University of Oregon"Joshua Glasgow’s blend of argumentation, analysis, and experimental philosophy is deeply engaging and thought-provoking. His arguments about the conservation of race, its reality, the meaning of ordinary racial terms, and the folk conception of race will be a reference point for debates within the philosophy of race for years to come."- Ronald Sundstrom, University of San Francisco"Glasgow has written a very readable and useful book on race theory. . . . In each section he gives definitions and explanations that are helpful and insightful. This is an important book for introducing the concepts, theories, and methodologies involved in race discussions."- L.L. Lovern, Valdosta State University, CHOICE, Vol. 46, No. 11, August 2009
