The ten essays in this collection were written to celebrate the 50th anniversary of the lectures which became Wilfrid Sellars's Empiricism and the Philosophy of Mind, one of the crowning achievements of 20th-century analytic philosophy. Both appreciative and critical of Sellars's accomplishment, they engage with his treatment of crucial issues in metaphysics and epistemology. The topics include the standing of empiricism, Sellars's complex treatment of perception, his dissatisfaction with both foundationalist and coherentist epistemologies, his commitment to realism, and the status of the normative (the "logical space of reasons" and the "manifest image"). The volume shows how vibrant Sellarsian philosophy remains in the 21st century.
