Some more similarities between Peirce and Skinner

C. S. Peirce is noted for pioneering a variety of views, and the case is made here for the similarities and parallels between his views and B. E Skinner's radical behaviorism. In addition to parallels previously noted, these similarities include an advancement of experimental science, a behavioral psychology, a shift from nominalism to realism, an opposition to positivism, a selectionist account for strengthening behavior, the importance of a community of selves, a recursive approach to method, and the probabilistic nature of truth. Questions are raised as to the extent to which Skinner's radical behaviorism, as distinguished from his S-R positivism, may be seen as an extension of Peirce's pragmatism.
