Origins of Objectivity is Tyler Burge's long-awaited first monograph. It is an absolutely terrific work, conceived and executed at a scale and level of ambition rarely seen in contemporary philosophy. The book's primary aim is to contribute a theory of perception; more broadly, however, it also delivers a subtle and nuanced query into the place of distinctively psychological capacities in the natural order. One can only hope that the book will come to shape discussions inthe philosophy of mind and perception for years to come, not just in terms of its specific doctrines 'e" bold and persuasive as they are 'e" but also in terms of its methods. Burge's integration of insights from a vast range of empirical sciences with philosophical reflection stands out as a model for emulation.
