This volume explores the thought and intellectual legacy of Wilfrid Sellars (1912-1989), one of the most influential philosophers of the twentieth century. A team of experts critically examines the groundbreaking means by which Sellars sought to integrate our thought, perception, and rational agency within a naturalistic outlook on reality. This collection is a fitting tribute to Sellars by some of his most prominent heirs and should be of interest to Sellarsians of any stripe.
