Kant's transcendental deduction yields twelve and only twelve categories, but behind the argument lie two assumptions: 1) newtonian physics gives unalterable and certain knowledge of phenomena; 2) the subject-predicate logic is the correct tool for the analysis of knowledge. this article examines the place of both assumptions in kant's doctrine and the relevance of each today. both assumptions must be discarded, and with them goes the rigidity of the categories; but the article shows how kant's important insights into the place (...) of the categories in knowledge can be salvaged.

The low rates of regular exercise and overall physical activity (PA) in the general population represent a significant public health challenge. Previous research suggests that, for many people, exercise leads to a negative affective response and, in turn, reduced likelihood of future exercise. The purpose of this paper is to examine this exercise–affect–adherence relationship from an evolutionary perspective. Specifically, we argue that low rates of physical exercise in the general population are a function of the evolved human tendency to avoid (...) unnecessary physical exertion. This innate tendency evolved because it allowed our evolutionary ancestors to conserve energy for physical activities that had immediate adaptive utility such as pursuing prey, escaping predators, and engaging in social and reproductive behaviors. The commonly observed negative affective response to exercise is an evolved proximate psychological mechanism through which humans avoid unnecessary energy expenditure. The fact that the human tendencies toward negative affective response to and avoidance of unnecessary physical activities are innate does not mean that they are unchangeable. Indeed, it is only because of human-engineered changes in our environmental conditions (i.e., it is no longer necessary for us to work for our food) that our predisposition to avoid unnecessary physical exertion has become a liability. Thus, it is well within our capabilities to reengineer our environments to once again make PA necessary or, at least, to serve an immediate functional purpose. We propose a two-pronged approach to PA promotion based on this evolutionary functional perspective: first, to promote exercise and other physical activities that are perceived to have an immediate purpose, and second, to instill greater perceived purpose for a wider range of physical activities. We posit that these strategies are more likely to result in more positive (or less negative) affective responses to exercise, better adherence to exercise programs, and higher rates of overall PA.

In lieu of an abstract, here is a brief excerpt of the content:Pragmatism and a Behavioral Theory of Meaning HAROLD N. LEE IT HAS BEEN ALMOST ONE HUNDRED YEARS since the publication of Peirce's article "How to Make Our Ideas Clear" in the Popular Science Monthly. There Peirce stated what came to be called The Pragmatic Maxim. 1 Since then pragmatism has been developed and expounded by many proponents. Some of the developments have differed markedly from others, and some (...) of these differences are not easily compatible.2 Opponents of pragmatism have differed in their interpretations in step with the proponents. As the century is rounded out, we should be able to review the scene and appraise the maneuvers and sorties. Just what is pragmatism? It has often been held that pragmatism is not the name of a philosophy but only of a loose collection of philosophies having at most a faint family resemblance. It must be admitted that this interpretation received some support from James's genial and hospitable personality. Nevertheless, I think it is incorrect. We can now discern a central, characterizing position which the early proponents of the new movement were setting forth and defending; and we can free it from misunderstandings that have historically beset it. It was apparent from the first that action and the consequences of action were to be regarded as fundamental to the new position, but this characterization is vague enough to cover many incompatible special developments. It can be sharpened now, after a century of discussion and debate, and we can identify the respects in which action is central, thus separating the general position from the special interests belonging to one or another of the individuals who were its early advocates. Such clarification will reveal a pragmatism that is highly relevant to contemporary philosophy. I. Peirce proposed his maxim as a theory of meaning: the clear apprehension of an idea is to be obtained by considering the effects or consequences on future possible action that follow from the idea. Meanings consist in the possible effects of present experience on future behavior. In accordance with the pragmatic maxim, I shall take the behavioral theory of meaning and the behavioral theory of knowledge that issues from it to be the central position of pragmatism. What is either incompatible or unnecessary to this behavioral core is expendable, and if it has contributed to the misunderstanding or misrepresentation of the core, it should be abandoned in the further development of pragmatism. Both Peirce and James presented pragmatism primarily 1 Collected Papers o/ Charles Sanders Peirce, vols. 1-6 ed. by Charles Hartshorne and Paul Weiss; vols. 7-8 ed. by Arthur W.

[435] 436 HISTORY OF PHILOSOPHY as a method, but in the philosophies of both, and of Dewey as well, the emphasis on method is often obscured by specific doctrines in some field such as ontology, epistemology or ethics; and in the cases especially of James and Dewey, it was the special doetrines that elicited the bulk of the adverse criticism. The pragmatism of all the early pragmatists was so mixed with other advocacies and causes that it was often difficult to distinguish between what should be called pragmatic and what should not. Pragmatism did not emerge full-blown in stark separateness. Certain auxiliary positions that revolve around the behavioral theory of meaning also characterize pragmatism. They are to be found in the writings of all the early pragmatists and both yield and receive systematic support from the behavioral theory of meaning. Together with the theory of meaning they demarcate the core of pragmatism. The list is as follows: (1) Meaning and knowledge are behaviorally defined. (2) The various forms of pragmatism share an evolutionary, naturalistic outlook. (3) They all emphasize, in harmony with the evolutionary outlook, process and time-especially the continuity of passage and temporality. (4) They all show, in harmony with the continuity of process, a tendency to reject Cartesian dualism... (shrink)
