Wilfrid Stalker Sellars (1912-1989) was a profound philosopher who left an indelible mark on mid-to-late 20th century Anglo-American philosophy. His stated goal was "to formulate a scientifically oriented, naturalistic realism which would ‘save the appearances,’" and towards this end he wrote a number of essays that covered topics in metaphysics, epistemology, philosophy of mind, philosophy of science, and ethics, as well as in the history of philosophy. Sellars was broadly educated in philosophy, drawing influences from ancient philosophy, German Idealism, logical positivism, critical realism, and ordinary language philosophy. His work was imbued with a deep respect for philosophy’s history. He is most famous for his attack on the "myth of the given" and his development of a non-foundationalistic epistemology, for his distinction between the "manifest image" and the "scientific image" of humanity in the world, for his proposal that psychological concepts are like theoretical concepts, and for his scientific realism. Sellars can claim the first explicit formulation of a functionalist treatment of intentional states, an early recognition of the "hard problem" of sensory consciousness, and a thoroughgoing nominalism, as well as rich interpretations of historical figures in philosophy.
