This book presents a thorough overview of a model of human functioning based on the idea that behavior is goal-directed and regulated by feedback control processes. It describes feedback processes and their application to behavior, considers goals and the idea that goals are organized hierarchically, examines affect as deriving from a different kind of feedback process, and analyzes how success expectancies influence whether people keep trying to attain goals or disengage. Later sections consider a series of emerging themes, including dynamic (...) systems as a model for shifting among goals, catastrophe theory as a model for persistence, and the question of whether behavior is controlled or instead 'emerges'. Three chapters consider the implications of these various ideas for understanding maladaptive behavior, and the closing chapter asks whether goals are a necessity of life. Throughout, theory is presented in the context of diverse issues that link the theory to other literatures. (shrink)

This book is concerned with `the problem of existence in mathematics'. It develops a mathematical system in which there are no existence assertions but only assertions of the constructibility of certain sorts of things. It explores the philosophical implications of such an approach through an examination of the writings of Field, Burgess, Maddy, Kitcher, and others.

A powerful challenge to some highly influential theories, this book offers a thorough critical exposition of modal realism, the philosophical doctrine that many possible worlds exist of which our own universe is just one. Chihara challenges this claim and offers a new argument for modality without worlds.

This paper explores some lines of argument in wittgenstein's post-Tractatus writings in order to indicate the relations between wittgenstein's philosophical psychology, On the one hand, And his philosophy of language, His epistemology, And his doctrines about the nature of philosophical analysis on the other. The authors maintain that the later writings of wittgenstein express a coherent doctrine in which an operationalistic analysis of confirmation and language supports a philosophical psychology of a type the authors call "logical behaviorism." they also maintain (...) that there are good grounds for rejecting the philosophical theory implicit in wittgenstein's later works. In particular, They first argue that wittgenstein's position leads to some implausible conclusions concerning the nature of language and psychology; second, They maintain that the arguments wittgenstein provides are inconclusive; and third, They sketch an alternative position which they believe avoids many of the difficulties implicit in wittgenstein's philosophy.

An Internet survey revealed that day-of-the-week (DOW) stereotypes (i.e., “Monday blues”, “Wednesday hump day”, “TGIF”, etc.) were pronounced when subjects predicted their moods for each day of the upcoming week, less obvious when they remembered their moods from each day of the preceding week, and least apparent in the momentary moods they actually experienced on each day. In a second study involving 2-hour, in-home interviews, subjects reporting looking forward to weekends because of the lack of structure and discipline and the (...) freedom to choose activities, yet much of their weekend time was spent fulfilling a need to be productive, which often involved activities that, in many ways, simulated paid work. The content of these interviews suggested that people tend to overvalue future discretionary time on the weekend, assuming that two days of uninterrupted idle time will be more enjoyable than it actually is. In a more general sense, these results suggest that the predicted and remembered moods in the initial survey were driven by DOW stereotypes, which facilitated rapid judgements given the simple scaled response format. However, the depth interviews revealed that moods experienced throughout the week are more nuanced in terms of how they are remembered, described, and linked to recently passed, current, and immediately anticipated events, perhaps explaining why DOW stereotypes were less obvious in the reported momentary moods.

We propose a model of motivated skepticism that helps explain when and why citizens are biased information processors. Two experimental studies explore how citizens evaluate arguments about affirmative action and gun control, finding strong evidence of a prior attitude effect such that attitudinally congruent arguments are evaluated as stronger than attitudinally incongruent arguments. When reading pro and con arguments, participants (Ps) counterargue the contrary arguments and uncritically accept supporting arguments, evidence of a disconfirmation bias. We also find a confirmation bias—the (...) seeking out of confirmatory evidence—when Ps are free to self-select the source of the arguments they read. Both the confirmation and disconfirmation biases lead to attitude polarization—the strengthening of t2 over t1 attitudes—especially among those with the strongest priors and highest levels of political sophistication. We conclude with a discussion of the normative implications of these findings for rational behavior in a democracy. (shrink)

Environmental policy has a size bias. Small organisms, such as microorganisms, command less attention from environmentalists than larger organisms, such as birds and large mammals. A simple thought experiment involving microscopic polar bears and giant microorganisms illustrates the importance of size in environmental ethics. Given the positive correlation between body size and brain size, there is probably a basis for a size bias in environmental ethics using ethical frameworks based on conations. This paper examines the relevance of the size of (...) organisms in environmental ethics. It emphasizes the need to understand the theoretical reasons for the importance of size, and not to base a size bias merely on a subjective anthropocentric prejudice favouring large organisms.

This paper argues that the pluralist ethos of today’s world requires dialogue, i.e., the construction of shared meaning through a plurality of perspectives. This, in turn, requires that partners in dialogue overcome the perspective of the “master self” who claims universal legislative authority in its quest for epistemic closure. Dialogue requires the cultivation and development of a dialogical self-identity that reflects the ability to co-construct shared meaning without the erasure or suppression of differences.
