This paper explores the complex relationship between the plant evolutionist G. Ledyard Stebbins and the animal evolutionist Theodosius Dobzhansky. The manner in which the plant evolution was brought into line, synthesized, or rendered consistent with the understanding of animal evolution (and especially insect evolution) is explored, especially as it culminated with the publication of Stebbins's 1950 book Variation and Evolution in Plants. The paper explores the multi-directional traffic of influence between Stebbins and Dobzhansky, but also their social and professional networks (...) that linked plant evolutionists like Stebbins with Edgar Anderson, Carl Epling, and the 'Carnegie team' of Jens Clausen, David Keck, and William Hiesey with collaborators on the animal side like I. Michael Lerner, Sewall Wright and L.C. Dunn and other 'architects' of the synthesis like Ernst Mayr, Julian Huxley and George Gaylord Simpson. The compatibility in training, work styles, methodologies, goals, field sites, levels of analysis, and even choice of organismic systems is explored between Stebbins and Dobzhansky. Finally, the extent to which coevolution between plants and insects is reflected in the relationship is explored, as is the power dynamic in the relationship between two of the most visible figures associated with the evolutionary synthesis.

The major competing statistical paradigms share a common remarkable but unremarked thread: in many of their inferential applications, different probability interpretations are combined. How this plays out in different theories of inference depends on the type of question asked. We distinguish four question types: confirmation, evidence, decision, and prediction. We show that Bayesian confirmation theory mixes what are intuitively “subjective” and “objective” interpretations of probability, whereas the likelihood-based account of evidence melds three conceptions of what constitutes an “objective” probability.

In two studies, we used the Ethics Position Questionnaire (EPQ) to investigate the relationship between individual differences in moral philosophy, involvement in the animal rights movement, and attitudes toward the treatment of animals. In the first, 600 animal rights activists attending a national demonstration and 266 nonactivist college students were given the EPQ. Analysis of the returns from 157 activists and 198 students indicated that the activists were more likely than the students to hold an "absolutist" moral orientation (high idealism, (...) low relativism). In the second study, 169 students were given the EPQ with a scale designed to measure attitudes toward the treatment of animals. Multiple regression showed that gender and the EPQ dimension of idealism were related to attitudes toward animal use. (shrink)

With their comprehensive categorization of “ambivalence-related phenomena,” Moore et al. helpfully clarify and contextualize these decisional states as they arise in patient care. Given the...

This book explores the writings of Inis L. Claude, Jr., a preeminent scholar on international relations, to define a new approach to the study of international relations. Pragmatic liberalism, an "in-between" approach, argues that a liberal world order can be sustained and promoted by the pragmatic application of liberal principles.

THE CENTRALITY OF "SYMPATHY" to Adam Smith's Theory of Moral Sentiments points to the centrality of love in the book. While Smith delineates a somewhat unusual, technical sense of "sympathy", his actual use of the term frequently slips into its more ordinary sense of "compassion" or affectionate fellow feeling. This no doubt intentional equivocation on Smith's part helps suffuse the book with these themes, to the point that, without much exaggeration, one could say that the Theory of Moral Sentiments is (...) generally about love: our need for love and sympathy, love as friendship, self-love, the love of praise and praiseworthiness, the love of beauty. Even in the Wealth of Nations, our loves are thought to be very important in explaining our behavior. Smith is unusual among modern moral philosophers in according so central a place to love in this broad sense, although of course Christianity made love a central theme in reflection on ethical life, and philosophers such as Hutcheson made benevolence a key virtue in their ethical systems. However, it is not our purpose to examine Smith's critique of Hutcheson or indeed of any of his predecessors. Rather we aim in this paper to reflect on his treatment of this topic. We shall do so in part by means of comparisons with Aristotle and Plato, first with respect to friendship and then with respect to love generally. Smith's writing is replete with classical references, raising the issue of the degree to which his thought is "ancient" or "modern." Friendship is arguably the pinnacle of social relations for the ancients, and thus it provides us with a useful device for determining the degree to which Smith's thought embodies classical moral and philosophical principles. The subtlety of Smith's interweaving of traditions will become visible as we reflect not just on the ways Smith's thought exhibits classical conceptions of friendship and love, but also on the ways he departs from them. For in at least one important respect, love is a closed book from Smith's standpoint, and thus, as it turns out, also at odds with classical friendship. (shrink)
