Polarization is a topic of intense interest among social scientists, but there is significant disagreement regarding the character of the phenomenon and little understanding of underlying mechanics. A first problem, we argue, is that polarization appears in the literature as not one concept but many. In the first part of the article, we distinguish nine phenomena that may be considered polarization, with suggestions of appropriate measures for each. In the second part of the article, we apply this analysis to evaluate (...) the types of polarization generated by the three major families of computational models proposing specific mechanisms of opinion polarization.

Biological science uses multiple species concepts. Order can be brought to this diversity if we recognize two key features. First, any given species concept is likely to have a patchwork structure, generated by repeated application of the concept to new domains. We illustrate this by showing how two species concepts (biological and ecological) have been modified from their initial eukaryotic applications to apply to prokaryotes. Second, both within and between patches, distinct species concepts may interact and hybridize. We thus defend (...) a semantic picture of the species concept as a collection of interacting patchwork structures. Thus, although not all uses of the term pick out the same kind of unit in nature, the diversity of uses reflects something more than mere polysemy. We suggest that the emphasis on the use of species to pick out natural units is itself problematic, because that is not the term’s sole function. In particular, species concepts are used to manage inquiry into processes of speciation, even when these processes do not produce clearly delimited species. (shrink)

For Émilie Du Châtelet, I argue, a central role of the principle of sufficient reason is to discriminate between better and worse explanations. Her principle of sufficient reason does not play this role for just any conceivable intellect: it specifically enables understanding for minds like ours. She develops this idea in terms of two criteria for the success of our explanations: “understanding how” and “understanding why.” These criteria can respectively be connected to the determinateness and contrastivity of explanations. The crucial (...) role Du Châtelet’s principle of sufficient reason plays in identifying good explanations is often overlooked in the literature, or else run together with questions about the justification and likelihood of explanations. An auxiliary goal of the article is to situate Du Châtelet’s principle of sufficient reason with respect to some of the general epistemological and metaphysical commitments of her Institutions de Physique, clarifying how it fits into the broader project of that work.

On the aesthetics and poetics of Hawks and Ford; their resurgence in film studies.

ABSTRACT This article distinguishes nine senses of polarization and provides formal measures for each one to refine the methodology used to describe polarization in distributions of attitudes. Each distinct concept is explained through a definition, formal measures, examples, and references. We then apply these measures to GSS data regarding political views, opinions on abortion, and religiosity—topics described as revealing social polarization. Previous breakdowns of polarization include domain-specific assumptions and focus on a subset of the distribution’s features. This has conflated multiple, (...) independent features of attitude distributions. The current work aims to extract the distinct senses of polarization and demonstrate that by becoming clearer on these distinctions we can better focus our efforts on substantive issues in social phenomena.

I examine Du Châtelet’s methodology for physics and metaphysics through the lens of her engagement with Newton’s Rules for Reasoning in Natural Philosophy. I first show that her early manuscript writings discuss and endorse these Rules. Then, I argue that her famous published account of hypotheses continues to invoke close analogues of Rules 3 and 4, despite various developments in her position. Once relevant experimental evidence and some basic constraints are met, it is legitimate to inductively generalize from observations; general (...) hypotheses can thereafter be assumed as true until contrary experiments show otherwise. I conclude by arguing that this account of induction plays an essential role in her metaphysics, both in an argument for simple substances—which has an inductive premise—and in her attempt to distinguish acceptable and unacceptable metaphysical commitments.

I reconstruct J. H. Lambert’s views on how practical grounds relate to epistemic features, such as certainty. I argue, first, that Lambert’s account of moral certainty does not involve any distinctively practical influence on theoretical belief. However, it does present an interesting form of fallibilism about justification as well as a denial of a tight link between knowledge and action. Second, I argue that for Lambert, the persistence principle that underwrites induction is supported by practical reasons to believe; this indicates (...) that Lambert is a moderate pragmatist about reasons for theoretical belief.

Draft for presentation at the 14th International Kant-Congress, September 2024. -/- Abstract: Kant claims we intuit infinite space. There’s a problem: Kant thinks full awareness of infinite space requires synthesis—the act of putting representations together and comprehending them as one. But our ability to synthesize is finite. Tobias Rosefeldt has argued in a recent paper that Kant’s notion of decomposing synthesis offers a solution. This talk criticizes Rosefeldt’s approach. First, Rosefeldt is committed to nonconceptual yet determinate awareness of (potentially) infinite (...) space, but I argue that such awareness is (1) prima facie implausible, as well as contravened by textual evidence from Kant’s (2a) definitions of ‘infinity’ and (2b) account of geometrical construction. Second, scrutiny of how Kant thinks awareness of potential infinity is afforded by geometrical construction (e.g., extending a line segment ad indefinitum) indicates no essential role for decomposing synthesis. Familiar synthesis from parts to wholes is sufficient. (shrink)

Retrieval practice, relative to further study, leads to long-term memory enhancement known as the “testing effect.” The neurobiological correlates of the testing effect at retrieval, when the learning benefits of testing are expressed, have not been fully characterized. Participants learned Swahili-English word-pairs and were assigned randomly to either the Study-Group or the Test-Group. After a week delay, all participants completed a cued-recall test while undergoing functional magnetic resonance imaging. The Test-Group had superior memory for the word-pairs compared to the Study-Group. (...) While both groups exhibited largely overlapping activations for remembered word-pairs, following an interaction analysis the Test-Group exhibited differential performance-related effects in the left putamen and left inferior parietal cortex near the supramarginal gyrus. The same analysis showed the Study-Group exhibited greater activations in the dorsal MPFC/pre-SMA and bilateral frontal operculum for remembered vs. forgotten word-pairs, whereas the Test-Group showed the opposite pattern of activation in the same regions. Thus, retrieval practice during training establishes a unique striatal-supramarginal network at retrieval that promotes enhanced memory performance. In contrast, study alone yields poorer memory but greater activations in frontal regions. (shrink)

The following article is a response to Virginia Aspe’s “The Political Dilemmas of the Transformations of Mexico: A Philosophical Approach”. My aim is to discuss some ideas developed by Aspe Armella, pointing out, from the perspective of the history of Mexican philosophy, both the successes of her approach, as well as some aspects that deserve more debate.

This introductory chapter provides an overview of the main themes covered in the present volume. It highlights the interdisciplinary approach taken in the choice of contributors to the volume which it is hoped will result in new perspectives on the philosophy of the Scottish Enlightenment. The chapter notes that the contributors approach Hutcheson, Hume, Smith, and Reid from new points of view, and other important figures and philosophical themes are discussed in terms of their contributions to a distinctively Scottish philosophical (...) scene in the eighteenth century. The chapter presents an outline of these themes including Scottish institutions and education, moral philosophy, aesthetic theory, religious thought, and historical and political theory. (shrink)

Perinatal palliative and hospice care (hereafter, perinatal hospice) is a novel approach to addressing a family’s varied needs following an adverse in utero diagnosis. Christian defenses of perinatal hospice tend to focus on its role as an ethical alternative to abortion. Although these analyses are important, they do not provide adequate grounds to characterize the wide range of goods realized through this compassionate form of care. This essay draws on an analysis of the Christian virtue of humility to highlight the (...) ways a Christian virtue-based defense of perinatal hospice can account for these goods. I argue that humility can play an important facilitating role in helping Christian physicians to meet the needs of families in profoundly difficult circumstances. (shrink)

This paper develops ‘primitive accumulation’ prior to and then in Karl Marx’s œuvre. By exploring the concept in Adam Smith and Sir James Steuart the paper highlights early influences on Marx’s evolving constructions. Marx’s construction in the Grundrisse begins with a logical determination much like Smith’s and moves, by drawing on Steuart, towards a socio-historical determination of a transitional violence. In Capital, ‘primitive accumulation’ still retains its transitional structure and delimited history, but it also points to the oppressive afterlife of (...) the processes of primitive accumulation. The political key to ‘primitive accumulation’ in Capital flows from determining primitive accumulation as temporally bounded, but having an afterlife in the oppressive social reproduction of capitalist societies. Against deriving political stakes through extended readings of ‘primitive accumulation’, this paper shows that an ‘originating’ view is textually accurate in a way that centres rather than sidelines the social reproduction of oppressions in capitalist societies.

Alastair Norcross has argued that there is no morally relevant difference between a person who eats meat and a person who tortures puppies in order to enjoy a certain gustatory sensation. We offer an objection to his argument.

This paper presents the data gathering of Matthew Fontine Maury at the U.S. Naval Observatory as pushing an epistemic boundary outside traditional laboratory walls. Maury's use and control of civilian navigators explicates the development of an astronomic epistemology deeply embedded in nineteenth century American society. In conclusion, following the movement of epistemic boundaries is offered as a guide to crucial moments in the development of a multifaceted modernity.

This is an excerpt from the contentIn the fall of 1970, as a visiting professor at London University, I was introduced to Mary Douglas by mutual friends at University College and the Institute of Education. In addition to having lunch periodically, we would join Basil Bernstein for a drink at a pub on Gower Street. Our meetings were casual and intellectually quite enjoyable. Mary was always quick to introduce research topics of mutual interest. When I joined Basil and she at (...) the pub, the discussion was more “aggressive” but always civil and stimulating. These episodic memories have never weakened, and as I recall those pleasant occasions I am reminded of the intellectual challenges that Basil and Mary created and their friendship.After my year in London, I did not see Mary for several years, but there were occasional messages that were given to me orally by mutual acquaintances. We did meet more often when she came on visits to the U.S., and especially after she took up residence in New York while at the Russell Sage Fo. (shrink)

Autonomy and responsibility are interrelated concepts crucial to the moral analysis of professional persons, organizations and institutions, and for the purpose of this paper, I focus on the persons, organizations, and institution of journalism. My paper’s thesis hinges on the notion that the confluence of the concepts of autonomy and responsibility creates a natural conceptual foundation for understanding moral praise and blame. Though in moral philosophy this notion has long been accepted, it has not yet been carefully applied to the (...) practice of journalism. Applying these concepts to journalism, I will argue, is crucial for accurately determining moral praise and blame, as it adds a structure to evaluating ethical behavior in a way that has not yet been put forward.

The speed with which Bradley became an historical backwater has probably made it easier to think of him as a second-rate philosopher, who was either incompetent or careless, or at any rate uninteresting, and to suppose that his arguments have been refuted as well as rejected. But as far as his metaphysics are concerned this is not the case. His project and his premises are not those of contemporary analytic philosophy, but his arguments are none the less rigorous for that; (...) and attempts to convict him of poor reasoning often redound little to the credit of his critics, as I hope to show. If Bradley is not much read nowadays then the reason is that fashions have changed, rather than that his philosophical shortcomings have been found out. (shrink)

Is there a contradiction in Stephen Colbert’s attitudes towards race? How can he consistently claim to be colorblind and yet hold a national search for a new "black friend"? I argue that Stephen is trying to claim rights and shirk responsibilities on matters of race relations in America, and that his famous notion of "truthiness" is an extension of this attitude to other areas of social and political discourse.

Some thoughts arising out of the fact that the University of Birmingham has recently gone through a re-branding exercise led by its administrators responsible for marketing, who failed miserably in marketing the exercise to staff and students within the University, as a result of which there is an online 'Save the Crest' petition that has attracted so many supporters that it made the national news.

The discussion below could be extended by pointing out that there is a fifth notion of freedom which refers to what you are free to do within a context of a game, a system of laws, a moral regime etc. This notion of freedom is close to the notion of permission. It is worth noting that the law may forbid something without enforcing that proscription. So many people constantly do what they are not free to do in this sense.

Maybe they have been made, but I missed them because I don’t read and listen enough, as most of my energies are focused elsewhere. Apologies if this is all old hat. Don’t feel you have to read on. In case others are interested, I shall put this on my web site at http://www.cs.bham.ac.uk/˜axs/gov/ My main point is that it is just silly to talk so much about universities and top-up fees without putting universities in the context of a complete policy (...) on post-school education. What I am offering is not a detailed policy, but a framework for thinking about the problem. Perhaps someone has already done this but I have never heard it mentioned in any of the public debates. I suspect that’s because this top-up fees issue is not part of a coherent policy but just a sort of religious commitment to a “new way”, like other things done by this government. I start with some comments on the fees issue, then go on to talk about how to think about post-school education, distinguishing several categories that need to be separated and funded differently as part of a joined-up system.

I argue that, in order to address the ideal world problem while remaining faithful to our concept of morality, Contractualists should no longer determine which actions I must perform by seeing whether they accord with certain principles for the general regulation of behavior. Instead, I argue, Contractualists should determine whether it is right or wrong for me to perform an action by evaluating any maxim that might be reflected by my action. I call the resulting view “Maxim Contractualism.” It states (...) that an agent’s action is morally required just in case any maxim that he might adopt that involves not performing that action is one that someone could reasonably reject. Finally, I argue that, although Act Contractualism also provides us with the materials to solve the Ideal World Problem, it is a worse solution because it cannot account for the fact that, sometimes, what would happen if I performed an action over time is relevant to whether I am permitted to perform that action right here, right now.

It is widely held that, in his pre-Critical works, Kant endorsed a necessitation account of laws of nature, where laws are grounded in essences or causal powers. Against this, I argue that the early Kant endorsed the priority of laws in explaining and unifying the natural world, as well as their irreducible role in in grounding natural necessity. Laws are a key constituent of Kant’s explanatory naturalism, rather than undermining it. By laying out neglected distinctions Kant draws among types of (...) natural law, grounding relations, and ontological levels, I show that his early works present a coherent and sophisticated laws-first account of the natural order.

This paper offers a unified explanation for the procreation asymmetry and the non-identity thesis – two of the most intractable puzzles in population ethics. According to the procreation asymmetry, there are moral reasons not to create lives that are not worth living but no moral reasons to create lives that are worth living. I explain the procreation asymmetry by arguing that there are moral reasons to prevent the bad, but no moral reasons to promote the good. Various explanations for the (...) procreation asymmetry have failed to explain the non-identity thesis: if one could create a person with a good life or a different person with a better life, one has a moral reason to create the better life. I argue that reflections on the misfortune of unfulfilled potential allow us to circumvent the non-identity problem. (shrink)

I present three versions of the argument from divine hiddenness that are grounded in moral considerations regarding how a just deity would act and auxiliary commitments that theists often have. First, I argue that the problem of hiddenness is made worse if one also holds that many will suffer in the afterlife due to not achieving a proper orientation towards God and the demands of morality in this life. Second, I argue that if any version of the moral argument for (...) theism is successful, then God has a very good reason to not remain hidden. Third, I argue that a just God would not allow people to do evil in her name. (shrink)

If social critique is to play a role in broad social transformation, then it must be able to engage with the terms that people use to understand their lives. This essay argues that we can find an important model for performing social critique in the quite different work of Jeffrey Stout and Judith Butler. For both, social critique must be immanent and it must make explicit the character of the norms by which people currently live. This model is especially important (...) in a situation where various moral and cultural traditions are confronting one another, and where it is necessary to work towards shared social and political goals. Stout and Butler present a method for achieving one's political goals by engaging with others on terms that they would recognize and seeking to transform the political structures they inhabit. Furthermore, their approaches provide helpful insights for further reflection on the critical possibilities in current ethnographic work. (shrink)
