A scientific community can be modeled as a collection of epistemic agents attempting to answer questions, in part by communicating about their hypotheses and results. We can treat the pathways of scientific communication as a network. When we do, it becomes clear that the interaction between the structure of the network and the nature of the question under investigation affects epistemic desiderata, including accuracy and speed to community consensus. Here we build on previous work, both our own and others’, in (...) order to get a firmer grasp on precisely which features of scientific communities interact with which features of scientific questions in order to influence epistemic outcomes.

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.

A first take, matured in later work, in modeling belief polarization.

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.

This collection of essays is the first of its kind to focus on the relationship between composition and identity. Twelve original articles--written by internationally renowned scholars and rising stars in the field--argue for and against the controversial doctrine that composition is identity.--Provided by publisher.

As sharing and secondary research use of biospecimens increases, IRBs and researchers face the challenge of protecting and respecting donors without comprehensive regulations addressing the human subject protection issues posed by biobanking. Variation in IRB biobanking policies about these issues has not been well documented.

Ontological pluralism holds that there are different ways of being. Truth pluralism holds that there are different ways of being true. Both views have received growing attention in recent literature, but so far there has been very little discussion of the connections between the views. The authors suggest that motivations typically given for truth pluralism have analogue motivations for ontological pluralism; they argue that while neither view entails the other, those who hold one view and wish to hold the other (...) will find natural routes by which to do so. The authors additionally identify some disanalogies between the views, by considering whether certain “mixed” problems commonly pressed against truth pluralism have analogues for ontological pluralism.

This paper is a systematic exploration of non-wellfounded mereology. Motivations and applications suggested in the literature are considered. Some are exotic like Borges’ Aleph, and the Trinity; other examples are less so, like time traveling bricks, and even Geach’s Tibbles the Cat. The authors point out that the transitivity of non-wellfounded parthood is inconsistent with extensionality. A non-wellfounded mereology is developed with careful consideration paid to rival notions of supplementation and fusion. Two equivalent axiomatizations are given, and are compared to (...) classical mereology. We provide a class of models with respect to which the non-wellfounded mereology is sound and complete.

The ultimate language of madness is that of reason.In short, under the chaotic and manifest delirium reigns the order of a secret delirium. In this second delirium, which is, in a sense, pure reason, reason delivered of all the external tinsel of dementia, is located the paradoxical truth of madness. And this in a double sense, since we find here both what makes madness true and what makes it truly madness.At the urging of his parents, Mr. A, a college-age young (...) man with a past diagnosis of Asperger’s...

Preview: /Aaron J. Wendland interviewed by Przemysław Bursztyka/ “What Good Is Philosophy?” took place on 17-19 March 2023, and it aimed to raise the funds required to establish a Centre for Civic Engagement at Kyiv Mohyla Academy. This Centre will provide support for academic and civic institutions in Ukraine to counteract the destabilizing impact that Russia’s invasion has had on Ukrainian higher education and civilian life. Keynotes at the conference were delivered by world-renowned author, Margaret Atwood, one of the (...) most celebrated scholars of Ukrainian history, Timothy Snyder, and two of Ukraine’s preeminent public intellectuals, Mychailo Wynnyckyj and Volodymyr Yermolenko. Lectures were also given by some of the most influential philosophers writing today, including Peter Adamson, Elizabeth Anderson, Seyla Benhabib, Agnes Callard, Quassim Cassam, Tim Crane, Simon Critchley, David Enoch, Peter Godfrey-Smith, Sally Haslanger, Angie Hobbs, Barry Lam, Melissa Lane, Dominic Lopes, Kate Manne, Jeff McMahan, Jennifer Nagel, Philip Pettit, Kieran Setiya, Jason Stanley, Timothy Williamson, and Jonathan Wolff. The closing remarks were delivered by Ukraine’s Ambassador to Canada, Yulia Kovaliv. This benefit event was designed to provide members of the public, individual academics, colleges and universities, professional associations, charitable foundations, and private companies with a way to support students, scholars, and civic institutions in Ukraine. The entire conference is now available to be viewed online via on the Munk School of Global Affairs and Public Policy’s YouTube channel. Here is the relevant link. I encourage everyone who watches the conference to make a donation to support students, scholars, and publicly engaged academics in Ukraine. All donations can be made here. And as the conference organizer, I am extremely grateful for any and every contribution to this cause. (shrink)

Jay Garfield and Graham Priest have attempted to make sense of Nāgārjuna’s apparently paradoxical uses of the catuṣkoṭi, or “four corners of truth”—according to which, a sentence may be true, false, both, or neither—by presenting a series of lattices. This chapter argues that Garfield and Priest’s lattices cannot ground the logic at play in Nāgārjuna’s Mūlamadhyamakakārikā; their semantic analysis cannot be an accurate analysis of Nāgārjuna’s arguments. The chapter argues for a new semantic interpretation that places greater emphasis on the (...) suggestion that the positive catuṣkoṭi requires disambiguation between the conventional and ultimate perspectives, whereas the negative catuṣkoṭi does not.

Liberalism has a complicated and sometimes uneasy relationship with truth. On one hand, liberalism requires that truth be widely valued and widely shared. It demands that governments be truthful and that citizens have ready access to numerous truths. Some liberals even take facilitating the discovery and dissemination of truth to be part of the raison d’être of liberal institutions. On the other hand, liberalism is averse to proclaiming or enforcing truth. It detaches truth from political legitimacy and deems certain truths (...) unfit to serve as bases of government. Some liberals have even suggested that liberal theory must work “without the concept of truth.” How has liberalism come to both demand truth and eschew it? This introductory section provides the beginnings of an answer by surveying some of the origins and core elements of liberal thought. (shrink)

Robert Card criticises our proposal for managing some conscientious objections in medicine. Unfortunately, he severely mischaracterises the nature of our proposal, its scope and its implications. He also overlooks the fact that our proposal is a compromise designed for a particular political context. We correct Card’s mischaracterisations, explain why we believe compromise is necessary and explain how we think proposed compromises should be evaluated.

When selecting approaches to pursuing social change, activists commonly evaluate the merits of individual approaches without considering the distributions of approaches already in their movements. This is a problem. I argue, from both general considerations about the division of cognitive labor and empirical evidence from sociology, that some distributions of approaches are better for movements than others and that activists can and should change these distributions for the better rather than for the worse.
