Each of these disciplines has a chapter devoted more or less exclusively to it: Chapter 2 is historical, chapter 3 is devoted to contempo- rary philosophy of color, and chapter 4 to contemporary science of color. From chapters 5 to 8 the integration occurs. Sometimes specific sections and subsections contain historical material that holds a mirror to the con- temporary issues under discussion. Other sections marshal empirical details pertinent to the philosophical debate at hand. The problem of color ontol- ogy is the theme running through the pages, and this unites these different branches of inquiry to a common purpose. Because this work devotes attention to three rather different disciplines, I have not covered any one of them in all of the depth or detail that would be expected in a study of singular focus. For example, I do not analyze all the philosophical arguments for and against color relationism with the thoroughness that I much admire in Cohen’ s (2009) T he Red and the Real . Indeed, I would refer the reader seeking such a focus to that important book. Similarly, my historical treatment is not that of a dedicated historian. In searching out the transitions and traditions in thought that have most shaped the problem of color ontology I have not attempted novel engage- ments with primary texts and have deferred to the readings of specialist historians. My use of this material has been selective, and may well appear superficial; I hope that the reader will allow some charity here since my goal is not ultimately that of a historical scholar, but of a philosopher tak- ing the long view. Any review of current science is destined to be out of date by the time it goes to press. While I have attempted to give an up to date, if partial, over- view of color psychophysics, psychology, and neurophysiology, it is likely
