Traditional model systems such as fly, mouse, and chick have formed the foundation of the EvoDevo research program. These animal systems have provided a wealth of information on the patterns and mechanisms of developmental change over large phylogenetic scales. However, the almost exclusive focus on individual embryos as model organisms has also limited the field’s ability to address the central roles that natural selection and life history adaptation play in the evolution of developmental systems. Likewise, focus on this small set (...) of “unitary” model organisms may also constrain the explanatory reach and theoretical robustness of EvoDevo if we consider that many core developmental processes like homeostatic regulation, ontogenetic differentiation, and norms of reaction are also manifest at other levels of biological organization, such as colonial organisms. The study of social insect systems can help bridge these considerable gaps in EvoDevo’s current approach. Because social insect colonies span the fine line between simple associations of “unitary” organisms and full-fledged “superorganisms,” these systems help elucidate what kinds of processes fundamentally characterize developmental systems and their evolution. What is more, the traits of social insect colonies show high degrees of population-level variability that can be linked directly to selective factors in the environment, making them ideal systems in which to more fully integrate EcoEvoDevo approaches.

The influence that philosophy of science has had on scientific practice is as controversial as it is undeniable, especially in the case of biology. The dynamic between philosophy and biology as disciplines has developed along two different lines that can be characterized as 'paternal', on the one hand, and more 'fraternal', on the other. The role Popperian principles of demarcation and falsifiability have played in both the systematics community as well as the ongoing evolution-creation debates illustrate these contrasting forms of (...) interdisciplinary engagement, underscoring the influence philosophy of science in shaping our contemporary understanding of biology in the North American context. However, a strict disciplinary distinction between philosophy and science may itself be a false dichotomy that risks hampering future development of the biological sciences. By actively engaging with philosophical considerations as an integral part of their scientific practice, nineteenth-century biologists offer an interesting counterpoint to current trends of overspecialization and provide a model of scientists who avoided extremes of antagonism with, or subservience to, philosophy.

Some have proposed that it is reasonable for an atheist to pursue a form of life shaped by engagement with theistic religious language and practice, once language and belief in God are interpreted in the appropriate non-realist manner. My aim is to defend this proposal in the face of several objections that have been raised against it. First, I engage in some conceptual spadework to distinguish more clearly some varieties of religious non-realism. Then, in response to two central objections, I (...) seek to articulate the most promising version of the view. I conclude by discussing some practical and moral objections to a non-realist form of religious life. (shrink)

_Plato_ explores the thought of a man who, in a literary career of fifty years, generated ideas that have pervaded history from antiquity to today. After laying out the basics of Plato’s intellectual development and considering his complex relationship with Socrates, Andrew Mason offers a thematic approach to help readers navigate through an often challenging body of work. Throughout, this concise volume traces the development of continuing themes in Plato’s dialogues and considers the relevance of these themes for modern (...) thought. Drawing on recent scholarship, this engaging introduction offers the ideal, up-to-date overview of a figure who remains essential reading in western history and philosophy. (shrink)

In the early months of 2020, the deadly Covid-19 disease spread rapidly around the world. In response, national and regional governments implemented a range of emergency lockdown measures, curtailing citizens’ movements and greatly limiting economic activity. More recently, as restrictions begin to be loosened or lifted entirely, the use of so-called contact tracing apps has figured prominently in many jurisdictions’ plans to reopen society. Critics have questioned the utility of such technologies on a number of fronts, both practical and ethical. (...) However, little has been said about the ways in which the normative design choices of app developers, and the products that result therefrom, might contribute to ethical reflection and wider political debate. Drawing from scholarship in critical design and human–computer interaction, this paper examines the development of a QR code-based tracking app called Zwaai (‘Wave’ in Dutch), where its designers explicitly positioned the app as an alternative to the predominant Bluetooth and GPS-based approaches. Through analyzing these designers’ choices, this paper argues that QR code infrastructures can work to surface a set ofethical–political seams, two of which are discussed here—responsibilizationandnetworked (im)permanence—that more ‘seamless’ protocols like Bluetooth actively aim to bypass, and which may go otherwise unnoticed by existing ethical frameworks.

We prove a number of results motivated by global questions of uniformity in computabi- lity theory, and universality of countable Borel equivalence relations. Our main technical tool is a game for constructing functions on free products of countable groups. We begin by investigating the notion of uniform universality, first proposed by Montalbán, Reimann and Slaman. This notion is a strengthened form of a countable Borel equivalence relation being universal, which we conjecture is equivalent to the usual notion. With this additional (...) uniformity hypothesis, we can answer many questions concerning how countable groups, probability measures, the subset relation, and increasing unions interact with universality. For many natural classes of countable Borel equivalence relations, we can also classify exactly which are uniformly universal. We also show the existence of refinements of Martin’s ultrafilter on Turing invariant Borel sets to the invariant Borel sets of equivalence relations that are much finer than Turing equivalence. For example, we construct such an ultrafilter for the orbit equivalence relation of the shift action of the free group on countably many generators. These ultrafilters imply a number of structural properties for these equivalence relations. (shrink)

Scientists from Einstein to Sagan have linked emotions like awe with the motivation for scientific inquiry, but no research has tested this possibility. Theoretical and empirical work from affective science, however, suggests that awe might be unique in motivating explanation and exploration of the physical world. We synthesize theories of awe with theories of the cognitive mechanisms related to learning, and offer a generative theoretical framework that can be used to test the effect of this emotion on early science learning.

Traditionally, the fiduciary duty of loyalty is implicated where corporate directors have conflicts of interest. In a major new decision, Stone v. Ritter, the Delaware Supreme Court determined that directors may also be disloyal when they act in bad faith. As a consequence, directors may be disloyal even when they have no conflicts of interest, and even when they intend to benefit their corporation. This Article reconciles this expanded fiduciary obligation with existing concepts of loyalty. The new loyalty is not (...) incoherent. Courts have adopted a recognizable understanding of loyal behavior - being “true” - that exists in other social spheres. Under this conception, loyal directors must not only act in the best interests of their corporation and its shareholders, they must also be honest with shareholders and comply with positive law. This Article then offers insights into the function of these expanded fiduciary duties. Although the new loyalty duties pose risks, there are good reasons to think they will provide net benefits. Following the recent Lyondell decision, it appears that the Stone case and its progeny will not result in significant revisions to the business judgment rule. However, the recent change in a director’s loyalty obligation may substantially lower information costs, giving better guidance to directors and simplifying coordination. In addition, the new conception of loyalty can also serve an important expressive function, enabling a more efficient level of trust among corporate actors, investors, and those who transact with the firm.

Ancient thought, particularly that of Plato and Aristotle, has played an important role in the development of the field of aesthetics, and the ideas of ancient thinkers are still influential and controversial today. "Ancient Aesthetics "introduces and discusses the central contributions of key ancient philosophers to this field, carefully considering their theories regarding the arts, especially poetry, but also music and visual art, as well as the theory of beauty more generally. With a focus on Plato and Aristotle, the philosophers (...) who have given us their thought about the arts at the greatest length, this volume also discusses Hellenistic aesthetics and Plotinus theory of beauty, which was to prove very influential in later thought. "Ancient Aesthetics "is a valuable contribution to its field, and will be of interest to students of philosophy and classics. ". (shrink)

Hume’s understanding of sympathy in section 2.1.11 of the Treatise—that it is a mental mechanism by means of which one sentient being can come to share the psychological states of another—has a particularly interesting implication. What the sympathizer receives, according to this definition, is the passing psychological “affection” that the object of his sympathy was experiencing at the moment of observation. Thus the psychological connection produced by Humean sympathy is not between the sympathizer and the “other” as a “whole person” (...) existing through time, but between the sympathizer and the other’s current mental state, detached from his or her diachronic psychological life. Some commentators profess themselves dissatisfied with the impersonality of this “limited sympathy”. John Bricke, for example, argues that the Humean sympathizer sympathizes with “atomistically rendered desires of some individual who is, thus far, of no further concern,” while Philip Mercer writes more bluntly that Hume’s definition omits the “practical concern for the other” that is the essence of sympathy’s contribution to moral psychology.

ABSTRACT In July 2018 the Twitter hashtag #secondcivilwarletters began trending as part of a collective response to conservative media personality Alex Jones’ warning that Democratic supporters were planning to launch a Second Civil War on Independence Day. The response consisted of tweets in the form of parodic letters written as though they were from the American Civil War period, and engaged in a collective form of political commentary and discussion, mostly displaying an anti-Republican and anti-Trump sentiment. This article analyses the (...) different ways the tweeters used Twitter and the #secondcivilwarletters hashtag to engage in the humorous discursive delegitimisation of President Trump and Republicans. It was found that the strategies of authorisation, moral evaluation, rationalisation, and mythopoeisis featured prominently in the tweets and, combined with the humorous edge, nourished the political participation and discourse of this online community.

Antifertility vaccination is a proposed method of contraception that induces infertility through an immunological response to specific reproductive targets. The following essay analyzes several peer-reviewed articles to identify these potential targets and then determines the bioethical implications of vac­cine use through the lens of Thomistic personalism. Vaccines that intentionally utilize a contraceptive action violate the principles of totality, integrity, and inseparability; while vaccines that intentionally utilize a contragestive action additionally violate the principles of inviolability of human life and non-maleficence. An (...) exception may exist in cases where application is directed at the treatment of specific pathologies. These cases may be tolerated using the principle of double effect when certain conditions are met. Furthermore, the safeguarding of informed consent may prove problematic if contraception is integrated with established vaccine programs. (shrink)

There is a traditional view concerning the relation between mind and matter, knower and known. It posits a bifurcation between the two, maintaining, as Ryle puts it, that mind and matter are two distinct orders of existence. This traditional view comes, in large part, from Descartes. James rejects the traditional view, arguing instead for a close relationship between thought and object. His argument contains two components. The first stresses the close functional relationship between thought and object in our everyday experience. (...) James argues here that true thoughts do or can lead us to their objects, culminating in prosperous interaction with them. The second part of James's argument holds that in pure experience--the original flow of data within which all distinctions are to be made--there is no distinction yet made between mind and matter, knower and known. These distinctions arise only later as conceptual tools for bringing organization to the original presentations. Any given element of pure experience is categorized twice, once as an element of the physical world, and a second time as an element of the perceiver's own mental history. The conclusion, then, is that James: shows that thought and object work together in a close functional relationship in ordinary experience; and argues that they arise from one homogeneous pure experience. ;A number of criticisms were directed against James's view, including: Lovejoy's, arguing that the incompatibilities of thought and object preclude the possibility of their arising from one homogeneous source; Russell's and Perry's, arguing that James's theory is unable to extricate itself from idealism; Miller's and Bode's, arguing that James's view contradicts one of his own important tenets in The Principles of Psychology; and an argument that James is unable to account for the agency by means of which pure experience gets organized. ;James can reply plausibly to all of these criticisms including the difficult issue of the self. On this question a consistent understanding of James's basic assumptions is required. ;Finally, James's viewpoint offers an interesting critical perspective on certain contemporary theories of mind-brain identity.

This essay reviews John Gardner’s recent books, From Personal Life to Private Law, and Torts and Other Wrongs. Both books offer profound insights into private law’s concerns with justice and our reasons for action. The essay focuses on Gardner’s continuity thesis, and in particular on his idea that a third party may act on behalf of a wrongdoer as her delegee. Three settings are considered. First, I will discuss settings in which the state or another third party acts to remedy (...) a wrong without the wrongdoer’s consent. Second, I will review settings in which the legal remedies at issue – e.g., general damages or punitive damages – may not fit well with the idea that the state is acting on behalf of a wrongdoer. Third, I will analyze settings in which the state may be acting on behalf of right holders, yet still be concerned with the continuity thesis. Assessing each of these contexts offers further insights into the purpose of private law remedies. (shrink)

What can well-meaning people do about terror and genocide? The more we fight against systems of violence, the further we seem to sink into them. This book explores the lives and letters of ordinary and intellectual Germans who faced the ethical challenges of the Third Reich. Trained in history, literary criticism, philosophy, and theology, its four authors look at the role of myths, lies, non-conformity, irony, and modeling in cultivating a self. They explain how we might use these ordinary strategies (...) of selfhood to bear the burden of historical responsibility and be happy doing so.". (shrink)
