This book is a volume in the Penn Press Anniversary Collection. To mark its 125th anniversary in 2015, the University of Pennsylvania Press rereleased more than 1,100 titles from Penn Press's distinguished backlist from 1899-1999 that had fallen out of print. Spanning an entire century, the Anniversary Collection offers peer-reviewed scholarship in a wide range of subject areas.

The problem of scientific ethics or experimental morality creates for the scientific methodologist a profound dilemma. To the extent that he makes his investigations scientific he fails at the essence of morality. Conversely, if he attempts to found himself securely in morality, his efforts to become scientific lead to mere utilitarian “moralizing.” In the older language of Kant, the imperatives of morality are categorical; those of science, hypothetical. “Is” and “ought” are incommensurable categories, as they are for logical positivism which (...) simply accepts the dualism as irreducible and advises against what it views as the inevitable consequence of any attempted synthesis: confusion.

The boundaries of psychology have never been very distinctly defined and, as a consequence, science has witnessed frequent border incidents. But it obviously is not psychology alone which suffers from such lack of delineation, but its neighbors, the biological and social sciences, do as well. Cooperation between sciences becomes difficult under these conditions. All agree that psychology is the science of mind, but few agree to what “mind” is. At least within our century “mind” has been taken to be “behavior”, (...) for the present day outlook is that mind is behavior rather than that which is responsible for behavior. The metaphysical dynamism of a prime mover has been replaced by an experimental concept, i.e., one that is susceptible to scientific investigation. There is no need to review the complex history of behavioristic psychology in its many ramifications, ranging from Watson's mechanism to the various vitalistic teleologies. We turn instead to a fundamental problem on which there is little agreement: “What kind of behavior should be called mind?”. (shrink)

Human skin is the one authentic criterion of the universe which philosophers recognize when they appraise knowledge under their professional rubric, epistemology. By and large—except for a few of the great Critics and Sceptics—they view knowledge as a capacity, attribute, possession, or other mysterious inner quality of a “knower”; they view this knower as residing in or at a “body”; they view the body as cut off from the rest of the universe by a “skin”; all of which holds for (...) philosophizing physicists and physiologists even as for the professionals of the arcanum itself. If this assertion seems crude, one may recall that there are times when a bit of crudity is a fair physic for an inflamed subtlety. In the case before us the factual crudity lies in the use of “skin” for a criterion, not in our calling attention to the fact. The “skin” that is so used is, indeed, that of ancient anatomical schematism, unaffected by the transformation of understanding which modern physiological research has brought about. Yet if philosophers cease thus crudely to employ it, all their issues of epistemology will vanish, and the very type of attack they make on cognition will be discredited; whereupon the task of determining the status of knowledge itself will pass from their hands to those of the scientists who have taken over so many regions of philosophical arrogation in the past. This is what I propose here to show. (shrink)
