The history of 20th-century American psychology is often depicted as a history of the rise and fall of behaviorism. Although historians disagree about the theoretical and social factors that have contributed to the development of experimental psychology, there is widespread consensus about the growing and (later) declining influence of behaviorism between approximately 1920 and 1970. Because such wide-scope claims about the development of American psychology are typically based on small and unrepresentative samples of historical data, however, the question arises to what extent the received view is justified. This article aims to answer this question in two ways. First, we use advanced scientometric tools (e.g., bibliometric mapping, cocitation analysis, and term co-occurrence analysis) to quantitatively analyze the metadata of 119,278 articles published in American journals between 1920 and 1970. We reconstruct the development and structure of American psychology using cocitation and co-occurrence networks and argue that the standard story needs reappraising. Second, we argue that the question whether behaviorism was the “dominant” school of American psychology is historically misleading to begin with. Using the results of our bibliometric analyses, we argue that questions about the development of American psychology deserve more fine-grained answers.

This paper reconstructs the American reception of logical positivism in the early 1930s. I argue that Moritz Schlick (who had visiting positions at Stanford and

Quine's holistic empiricist account of scientific inquiry can be characterized by three constitutive principles: noncontradiction, universal revisability and pragmatic ordering. We show that these constitutive principles cannot be regarded as statements within an holistic empiricist's scientific theory of the world. This claim is a corollary of our refutation of Katz's [1998;2002] argument that holistic empiricism suffers from what he calls the Revisability Paradox. According to Katz, Quine's empiricism is incoherent because its constitutive principles cannot themselves be rationally revised. Using Gärdenfors and Makinson's logic of belief revision based on epistemic entrenchment, we argue that Katz wrongly assumes that the constitutive principles are statements within an holistic empiricist's theory of the world. Instead, we show that constitutive principles are best seen as properties of an holistic empiricist's theory of scientific inquiry and we submit that, without Katz's mistaken assumption, the paradox cannot be formulated. We argue that our perspective on the status of constitutive principles is perfectly in line with Quinean orthodoxy. In conclusion, we compare our findings with van Fraassen's [2002] argument that we should think of empiricism as a stance, rather than as a doctrine.

B. F. Skinner and W. V. Quine, arguably the two most influential proponents of behaviorism in mid-twentieth century psychology and philosophy, are often considered brothers in arms. They were close friends, they had remarkably parallel careers, and they both identified as behaviorists. Yet, surprisingly little is known about the relation between the two. How did Skinner and Quine develop their varieties of behaviorism? In what ways did they affect each other? And how similar are their behaviorisms to begin with? In this paper, I shed new light on the relation between Skinner and Quine by infusing the debate with a wide range of new and previously unexamined evidence from the personal and academic archives of Skinner and Quine.
