We investigate how the perceived uncertainty of a conditional affects a person's choice of conclusion. We use a novel procedure to introduce uncertainty by manipulating the conditional probability of the consequent given the antecedent. In Experiment 1, we show first that subjects reduce their choice of valid conclusions when a conditional is followed by an additional premise that makes the major premise uncertain. In this we replicate Byrne. These subjects choose, instead, a qualified conclusion expressing uncertainty. If subjects are given (...) a third statement that qualifies the likelihood of the additional premise, then the uncertainty of the conclusions they choose is systematically related to the suggested uncertainty. Experiment 2 confirms these observations in problems that omit the additional premise and qualify the first premise directly. Experiment 3 shows that the qualifying statement also affects the perceived probability of the consequent given the antecedent of the conditional. Experiment 4 investigates the effect of suggested uncertainty on the fallacies and shows that increases in uncertainty reduce the number of certain conclusions that are chosen while affirming the consequent but have no effect on denying the antecedent. We discuss our results in terms of rule theories and mental models and conclude that the latter give the most natural account of our results. (shrink)

Four experiments investigated uncertainty about a premise in a deductive argument as a function of the expertise of the speaker and of the conversational context. The procedure mimicked everyday reasoning in that participants were not told that the premises were to be treated as certain. The results showed that the perceived likelihood of a conclusion was greater when the major or the minor premise was uttered by an expert rather than a novice (Experiment 1). The results also showed that uncertainty (...) about the conclusion was higher when the major premise was uttered by a novice and an alternative premise by an expert, compared to when the major premise was uttered by an expert and the alternative by a novice (Experiment 2). Similarly, the believability of a conclusion was considerably lower when the minor premise was uttered by a novice and denied by an expert, as opposed to when an expert uttered the minor premise and a novice denied it (Experiment 3). Experiment 4 showed that the nature of the uncertainty induced by a denial of the minor premise depended on whether or not the context was a conversation. These results pose difficult problems for current theories of reasoning, as current theories are based on the results of experiments in which the premises are treated as certain. Our discussion of the results emphasises the importance of pragmatics in reasoning, namely, the role of general knowledge about the world in assessing the probability of a premise uttered by an expert or a novice and the role of interpretations of the premise based on pragmatic inferences in revising these initial probabilities.

The Earlier Letters of John Stuart Mill, published in two volumes in 1963, were well received by critics and scholars alike. The publication of these four volumes of later letters completes this edition of Mill's personal correspondence. These volumes contain over 1,800 letters, most never before published, and some sixty earlier letters that have come to light since the publication of the first two volumes of correspondence. The letters have been assembled from widely dispersed collections in the libraries of fifty-eight (...) institutions and of some thirty private collections in Britain and in other countries of the Commonwealth, Europe, and North America. In addition, many personal letters of which no originals sirvived have been located in contemporary periodicals or biographies of Mill's correspondence. (shrink)

This volume represents the proceedings of the annual Lectures on Moral Values in a Free Society at the University of Texas at Dallas, presented in 1983 on November 14 through 16.

This paper provides an evaluation of the spinoff of a for-profit company from the American Institute of Certified Public Accountants (AICPA), a nonprofit professional association. The evaluation is based on a review of the literature on public policy issues surrounding organizational conversions from nonprofit to for-profit legal status. Many criticisms of this for-profit spinoff were voiced by professional leaders and accounting regulators, and we demonstrate that these criticisms are grounded in widely recognized policy principles relating to nonprofit conversions. The public (...) policy issues raised by this study have implications for the governance of professional associations in all disciplines. (shrink)

Buddhisms and Deconstructions considers the connection between Buddhism and Derridean deconstruction, focusing on the work of Robert Magliola. Fourteen distinguished contributors discuss deconstruction and various Buddhisms—Indian, Tibetan, and Chinese —followed by an afterword in which Magliola responds directly to his critics.

In modern Western moral and political theory the notion of the liberal subject has flourished as the locus of moral experience, interpretation and critique. Through this conceptual lens on subjectivity, individuals are enabled to shape and regulate their interactions in arguably desirable ways, e.g. through principles of respect for persons and the constraints of reciprocal rights, and moral education has largely adopted this perspective. However, this article argues that some kinds of morally significant relations—those framed by social groups related to (...) each other through structures of hierarchical power—constitute a different kind of subjectivity that needs more theoretical and empirical attention. In contrast to four core characteristics of liberal subjectivity, a view of subjectivity that can be located in how individuals are members of particular kinds of social groups is offered. It is argued that unless it can accommodate working with attention to this form of subjectivity as well, moral education runs the risk of itself contributing to forms of oppression such as racism, instead of being a means of combating them.

The ethos of Justin Smith’s Nature, Human Nature, & Human Difference is expressed in the narrative of Anton Wilhelm Amo (~1703-53), an African-born​ slave who earned his doctoral degree in Philosophy at a European university and went on to teach at the Universities of Jena and Halle. Smith identifies Amo as a time-marker for diverging interpretations of race: race as inherently tethered to physical difference and race as inherited essential difference. Further, these interpretations of race are fastened to the discourse (...) of science and human diversity within modern Europe. Smith’s thesis maintains that the rise of the concept of race in philosophy begins with a divorcing of the soul from human nature and a movement to a naturalistic classification of human beings through taxonomies (e.g. botany, mineralogy and zoology), which dissolved into this dichotomy: an essential difference between people of reason and people of nature.
