Abstract

The present article is the third in a series of three that outlines the historical and conceptual background of B.F. Skinner’s radical behaviorism as a philosophy of science. Of special interest in this article is the intellectual context of a paper on operationism Skinner published in 1945, in which he first used the term “radical behaviorism” in print. Overall, Skinner’s radical behaviorism was a thoroughgoing behaviorism that provided a naturalistic account of the full range of human functioning, including the influence on both verbal and nonverbal behavior of phenomena identified as "subjective."
