Sellars’s philosophy of mind is deeply Kantian in the sense that he draws a sharp distinction between thought and sense.  The intentionality-body problem requires a different solution from the sensorium-body problem.  His philosophy of mind abandons many of the assumptions taken for granted by the Cartesian tradition (e.g., the transparent or self-intimating nature of the mental), moving towards a naturalism that respects the normative dimension of mind.  His key idea is that psychological concepts are like theoretical concepts in the sciences. Mentalistic concepts are thus as compatible with naturalism as any well-grounded scientific concept.
