In On the Genealogy of Color, Zed Adams argues for a historicized approach to conceptual analysis, by exploring the relevance of the history of color science for contemporary philosophical debates about color realism. Adams contends that two prominent positions in these debates, Cartesian anti-realism and Oxford realism, are both predicated on the assumption that the concept of color is ahistorical and unrevisable. Adams takes issue with this premise by offering a philosophical genealogy of the concept of color. This book makes a significant contribution to recent debates on philosophical methodology by demonstrating the efficacy of using the genealogical method to explore philosophical concepts, and will appeal to philosophers of perception, philosophers of mind, and metaphysicians.
