ABSTRACT
Schlick, Carnap, and Feigl are the most prominent neopositivists to formulate views on the mind-body problem. While their views differed from each other and changed over time, they were all committed to some form of physicalism, though a linguistic or conceptual rather than ontological form of it. In focus here are their views during the 1930s and later, though Schlick’s and Carnap’s early views also discussed to clarify the final opposing positions of Carnap and Feigl. All three philosophers were largely—entirely, in the case of Schlick and Feigl—concerned with sensations and sensory consciousness, or what Feigl came to call, after the psychologist E. C. Tolman, “raw feels” and what are now usually called “qualia” or “phenomenally conscious” mental states.
