ABSTRACT
It would be impossible in an article to survey all of the important developments on the mind-body problem that occurred in the 20th century. The author focuses on the key movements and themes that occupied philosophical attention over the course of the last 100 years. According to psychological behaviorists, psychology is best understood not as a science of mind but as a science of behavior. In contrast to logical behaviorism, ordinary language behaviorism was not motivated by verificationism. Rather, the behaviorism of philosophers like Ryle and Wittgenstein was primarily grounded in worries about the problem of other minds, a problem that is particularly acute if there are inner mental states that are private to each individual. Many philosophers have questioned the coherence of spectrum inversion. In particular, many philosophers of mind have begun to explore the coherence of positions like panpsychism and Russellian monism, both of which try to find a place for consciousness at the fundamental level of reality.
