Limits to Action: The Allocation of Individual Behavior presents the ideas and methods in the study of how individual organisms allocate their limited time and energy and the consequences of such allocation. The book is a survey of individual resource allocation, emphasizing the relationships of the concepts of utility, reinforcement, and Darwinian fitness. The chapters are arranged beginning with plants and general evolutionary considerations, through animal behavior in nature and laboratory, and ending with human behavior in suburb and institution. Topics (...) discussed include operant conditioning; the principle of diminishing returns; and issues in relation to mating strategies. Biologists, sociologists, economists, and psychologists will find the book interesting. (shrink)

The “A-not-B” error is consistent with an old memory principle, Jost's Law. Quantitative properties of the effect can be explained by a dynamic model for habituation that is also consistent with Jost. Piaget was well aware of the resemblance between adult memory errors and the “A-not-B” effect and, contrary to their assertions, Thelen et al.'s analysis of the object concept is much the same as his, though couched in different language.

The temporal pattern of the terminal response on periodic schedules depends on when responding begins. Pigeons pecking on fixed-interval and fixed-time schedules of food reinforcement responded, or accelerated, faster the later in an interval they began responding.

: This article is concerned with Newton's appropriation of Descartes' ontology of true and immutable natures in developing his theory of infinitely extended space. It contends that unless the part played by the Platonic distinction between "being a nature" and "having a nature" in Newton's thinking is properly appreciated the foundation of his doctrine of space in relation to God will not be fully understood. It also contends that Newton's Platonism is consistent with his empiricism once the mediating role is (...) made clear that the geometry of moving loci play in grounding his intuitions concerning infinite natures.

This article analyses the conception of virtue and vice in early modern Europe. It explains that there were two movements in conceptions of virtue during this period. The first is the Cartesian tradition wherein virtue is intimately related to the control of the passions and the other is the continuation of this theme in Britain in a more aesthetic version. This article describes how the concepts of virtue and vice were softened by an awakening interest in the social emotions and (...) in the relationship between moral goodness and happiness. (shrink)

Recent discussions of this issue have centered on the definition of the of philosophy in American public life and the ways of increasing philosophy's influence in the public arena.' This emphasis is prompted by the fact philosophers are worried about the future of the profession. After a tremendous expansion in the sixties, there has been a steady decline in the number college-teaching positions open to newly graduated philosophers. The market is bloated and Ph.D.'s in philosophy have increasing difficulty securing permanent (...) jobs. The American Philosophical Association has tried to address this situation in various ways and discussions of the state and future of the profession, once rare, are becoming common. I am quite sure that part of the motivation for this panel involved these reasons. Today, however, I am not going to address the issue of jobs, or the ways which we can increase the influence of philosophy. Rather, I am going concentrate on only two questions: First, Does philosophy have a place contemporary American public life? Second, Should philosophy have a place American public life? Because my answer to the first question is going to be negative, I am also going to discuss some of the reasons why I believe philosophy does not play a role in American public life. (shrink)

Comparative genomics has proven a fruitful approach to acquire many functional and evolutionary insights into core cellular processes. Here it is argued that in order to perform accurate and interesting comparative genomics, one first and foremost has to be able to recognize, postulate, and revise different evolutionary scenarios. After all, these studies lack a simple protocol, due to different proteins having different evolutionary dynamics and demanding different approaches. The authors here discuss this challenge from a practical (what are the observations?) (...) and conceptual (how do these indicate a specific evolutionary scenario?) viewpoint, with the aim to guide investigators who want to analyze the evolution of their protein(s) of interest. By sharing how the authors draft, test, and update such a scenario and how it directs their investigations, the authors hope to illuminate how to execute molecular evolution studies and how to interpret them.
