Galton and subsequent investigators find wide divergences in people's subjective reports of mental imagery. Such individual differences might be taken to explain the peculiarly irreconcilable disputes over the nature and cognitive significance of imagery which have periodically broken out among psychologists and philosophers. However, to so explain these disputes is itself to take a substantive and questionable position on the cognitive role of imagery. This article distinguishes three separable issues over which people can be "for" or "against" mental images. Conflation (...) of these issues can lead to theoretical differences being mistaken for experiential differences, even by theorists themselves. This is applied to the case of John B. Watson, who inaugurated a half-century of neglect of image psychology. Watson originally claimed to have vivid imagery; by 1913 he was denying the existence of images. This strange reversal, which made his behaviorism possible, is explicable as a "creative misconstrual" of Dunlap's "motor" theory of imagination. (shrink)

The Philosophical Legacy of Behaviorism is the first book to describe the unique contributions of a behavioral perspective to the major issues of philosophy. Leading behavioral philosophers and psychologists have contributed chapters on: the origins of behaviorism as a philosophy of science; the basic principles of behaviorism; ontology; epistemology; values and ethics; free will, determinism and self-control; and language and verbal behavior. A concluding chapter provides an overview of some scholarly criticisms of behavioral philosophy. Far from espousing a `black box' (...) perspective on human cognition and philosophical reasoning, behaviorism (as derived from the works of B. F. Skinner) represents a contemporary and viable approach to conceptualizing important philosophical and psychological issues. Audience: This work will make an excellent text for upper-level undergraduates and graduate students in the fields of philosophy and psychology, as well as being of interest to established scholars in those disciplines.

The seal of the a priori is imprinted on the reception of Kant's philosophy. Piaget's epistemological argumentation seems to ascribe knowledge a more fruitful constructiveness than Kant, seeing the a priori as rooted in unvarying reason. Yet, it seems, he failed to recognize the complexity of Kant's theory, which does not always follow a quid iuris line. Moments of experience, analysis and self-observation played more than a marginal role in his discovery of the a priori. Indeed, Kant himself raises the (...) question of ontogenetic category assimilation in a review which pre-empts Piaget, borrowing the category of `original acquisition' from the doctrine of the laws of natural right. And although Kant should not be elevated to the harbinger of the knowledge on development issues delivered thus far by the history of science and experiments, he did recognize the temporal reference of their categories in principle without resolving their validity in psychogenetic terms. Key Words: a priori • categories • genetic epistemology • Geneva School • neo-Kantianism • original acquisition • Jean Piaget • psychogenesis • self-observation. (shrink)
