This article examines the excitement that Adam Smith's Theory of Moral Sentiments generated in France during the French Revolution, focusing particularly on the writings of political theorists, participants and commentators such as the abbé Sieyès, Pierre-Louis Rœderer, the Marquis de Condorcet and Sophie de Grouchy Condorcet, who were dismayed at their political opponents’ use of Rousseau, and looked to Smith for an understanding of the passions that was compatible with democratic sovereignty and representative government. In the political context of the (...) early 1790s, clarifying the concept of natural sociability, which Rousseau had rejected, but Smith and Helvétius, in different ways, each regarded as indispensible to a society dependent on advanced division of labour, became a central concern in the public lectures delivered by Pierre-Louis Rœderer as the Terror took hold. ☆ My thanks to Emma Rothschild, Michael Sonenscher, Brian Young and other participants in the History of Political Thought Seminar, Oxford, and The Hexagonal Forum, Cambridge, where earlier versions of this paper were presented and helpfully discussed. I’m also grateful for comments on an earlier draft from Carolina Armenteros, Clare Jackson, Duncan Kelly, Michael Sonenscher and Richard Whatmore. (shrink)

George Boolos was one of the most prominent and influential logician-philosophers of recent times. This collection, nearly all chosen by Boolos himself shortly before his death, includes thirty papers on set theory, second-order logic, and plural quantifiers; on Frege, Dedekind, Cantor, and Russell; and on miscellaneous topics in logic and proof theory, including three papers on various aspects of the Gödel theorems. Boolos is universally recognized as the leader in the renewed interest in studies of Frege's work on logic and (...) the philosophy of mathematics. John Burgess has provided introductions to each of the three parts of the volume, and also an afterword on Boolos's technical work in provability logic, which is beyond the scope of this volume.

Beauty is a contested concept insofar as it seeks to mark a categorical distinction among the sources of pleasure, typically in terms of oppositions such as objective/subjective, universal/particular, necessity/contingency. Kant represents a culmination of this tradition in defining the judgment of beauty in terms of the requirement for universal agreement, modeling the judgment of beauty as closely as possible to ordinary factual judgments. A different tradition of thinking about beauty, however, while still seeking to mark a categorical distinction by reference (...) to the idea of necessity, finds the relevant sense of necessity not in conditions of agreement but necessities of erotic love and the sense of requirement felt toward its objects. This paper explores the consequences of taking this other tradition seriously, using Proust as a representative exemplar, as a way both of making sense of some of the features Kant ascribes to the concept of the beautiful, while avoiding the paradoxes stemming from his focus on the conditions for universal agreement.

According to Robert Fogelin, deep disagreements are disagreements about fundamental principles. He argues that deep disagreements cannot be rationally resolved. In this paper I argue against this thesis. A key part of the response depends upon the claim that disagreements can be rationally resolved not only by one participant rationally coming around to the other's point of view, but also by both of them rationally suspending judgment about the disputed proposition. I also claim that suspension of judgment may be the (...) rational response in the examples Fogelin characterizes as deep disagreements. I deny that this result has any troubling implications for critical thinking. (shrink)

Economists evaluate their models in terms of credibility. For example, Rothschild and Stiglitz argued from a model of a completive insurance market that under the “plausible” (632) assumption of information asymmetry, one can “credibly” infer the non-existence of equilibria in specific situations – despite the fact that, as they admit, the real ‘market … for insurance is probably not competitive’ (648).1 Another example is Richard Thaler’s column on anomalies of (micro-) economic theory. From 1987 to 2001, he headed (...) every article with the following sentence: ‘An empirical result is anomalous if it is difficult to rationalize, or if implausible assumptions are necessary to explain it within the paradigm’.2 Or, yet another example, Hans Lind concludes in a survey of mathematical models of rent control that ‘what is shown in the model[s]…is just one type of argument…for why a certain story is more credible than a competing story.

Chimpanzee and hunter-gatherer intergroup aggression differ in important ways, including humans having the ability to form peaceful relationships and alliances among groups. This paper nevertheless evaluates the hypothesis that intergroup aggression evolved according to the same functional principles in the two species—selection favoring a tendency to kill members of neighboring groups when killing could be carried out safely. According to this idea chimpanzees and humans are equally risk-averse when fighting. When self-sacrificial war practices are found in humans, therefore, they result (...) from cultural systems of reward, punishment, and coercion rather than evolved adaptations to greater risk-taking. To test this “chimpanzee model,” we review intergroup fighting in chimpanzees and nomadic hunter-gatherers living with other nomadic hunter-gatherers as neighbors. Whether humans have evolved specific psychological adaptations for war is unknown, but current evidence suggests that the chimpanzee model is an appropriate starting point for analyzing the biological and cultural evolution of warfare.

More than any other textbook, Moore and Parker's Critical Thinking has defined the structure and content of the critical thinking course at colleges and universities across the country--and has done so with a witty writing style that students enjoy. Now in full-color, the eighth edition brings the concepts of critical thinking to life in vivid detail, with current examples relevant to today's students.

This volume collects a number of important and revealing interviews with Richard Rorty, spanning more than two decades of his public intellectual commentary, engagement, and criticism. In colloquial language, Rorty discusses the relevance and nonrelevance of philosophy to American political and public life. The collection also provides a candid set of insights into Rorty's political beliefs and his commitment to the labor and union traditions in this country. Finally, the interviews reveal Rorty to be a deeply engaged social thinker (...) and observer. (shrink)

The physical limitations, due to quantum mechanics, on the functioning of computers are analyzed.

The four principles approach to biomedical ethics points to respect for autonomy, beneficence, non-maleficence and justice as the norms that should guide moral agents working in the biosciences, and particularly in health care. While the approach is well known, it is not without its critics. In this paper, which is primarily aimed at health professionals and students (from various disciplines) who are studying health care ethics, I consider four problems with the four principles, which respectively claim that the approach is (...) imperialist, inapplicable, inconsistent and inadequate. In keeping with the aims of the ‘five-minute focus’, the primary objective is to introduce these debates, rather than seek to resolve them. However, I will suggest that the approach does have its merits, not least for time-pressed clinicians who are keen to keep an eye on the ethical dimensions of their practices, and for students training in the health care professions, provided that they appreciate that the approach provides only a starting point for, and not the end point of, moral deliberation.

Why do people in more unequal societies have worse health and shorter lives than those in less unequal ones? Why do more unequal societies tend to have more violence and weaker community life? This paper discusses the research evidence on the psychosocial pathways which suggest how and why we are affected by inequality.How big income differences are in any society seems to serve as an indicator of the scale of social differentiation and social distances within it. The evidence shows that (...) more hierarchical societies incur a wide range of social costs reflecting the corrosive effects of inequality. But why are we so sensitive to inequality? Epidemiological research on health inequalities and the social determinants of health has demonstrated that the quality of the social environment has powerful effects on health. Particularly important are social status, friendship and early childhood experience. The indications are that poor health may share causal pathways with many other social problems associated with relative deprivation - including violence.Summarizing my recent book, The Impact of Inequality , this paper provides an account of how inequality gets under the skin to affect both health and wellbeing. Rather than making comparisons with some impractical state of complete equality, all the evidence presented shows the importance of the differences in inequality between different states of the USA or between different developed market democracies: it shows that even small increases in equality matter.

This comprehensive study of probability considers the approaches of Pascal, Laplace, Poisson, and others. It also discusses Laws of Large Numbers, the theory of errors, and other relevant topics.

This paper consists in a study of Leibniz’s argument for the infinite plurality of substances, versions of which recur throughout his mature corpus. It goes roughly as follows: since every body is actually divided into further bodies, it is therefore not a unity but an infinite aggregate; the reality of an aggregate, however, reduces to the reality of the unities it presupposes; the reality of body, therefore, entails an actual infinity of constituent unities everywhere in it. I argue that this (...) depends on a generalized notion of aggregation, according to which a thing may be an aggregate of its constituents if every one of its actual parts presupposes such constituents, but is not composed from them. One of the premises of this argument is the reality of bodies. If this premise is denied, Leibniz’s argument for the infinitude of substances, and even of their plurality, cannot go through.

“Ethical investing” is interpreted in the following paper to be the use of non-financial normative criteria by investors in the choice ofsecurities for their portfolios.Ethical investors may aim at fulfilling duties they feel they have, possibly including increasing the amount of good in society through theconsequences of their buying and selling behavior. The main duties are those of not-profiting from bad corporate behavior and of punishing bad firms. The main consequence desired is that managers manage corporations in a more ethical (...) manner. But ethical investors also aim at receiving returns based on the market risk of their investments.If the aim of managers is to maximize shareholder wealth, then ethical investors can fulfill their duties or achieve their desired consequences only if their trading activities affect shareholder wealth, i.e., share price. A theoretical argument is presented to show that this trading activity will not affect share price or return. In addition, reference is made to results of empirical studies which show that ethical stocks yield market returns, i.e., that the share price of ethical firms is unaffected by the actions of ethical investors.If the trading activity of ethical investors fails to affect share price and return, then these investors fail to fulfill any of their goals or to achieve their ends.

In this third edition of "John Locke", the text is divided into three parts. The first is biographical, giving an account of the development of Locke's mind. The second expounds the teaching of the "Essay", and relates this to its background; while the third deals with Locke's teaching in political theory, moral philosophy, education, and religion. -- From publisher's description.

In this piece we explore the COVID pandemic as an opportunity for the articulation and realization of digital health futures. Our discussion draws on an engagement with emergent discourse around COVID-19 and ongoing work on imaginaries of future care associated with digital tools for the detection of cognitive decline and the risk of dementia. We describe how the post-COVID futures of digital health are narrated in terms of the timing and speed with which they are being brought into being, as (...) market actors attempt to establish the scale and durability of the COVID transformation. However, we also point to the particularly spatial changes to medical practice they envisage. In a time of distancing and isolation, the ability to operate effectively at a distance has become integral to the future of medical assessment, diagnosis and care. However, spatialized promises of digital health and the ability to act remotely are unevenly spread – some organizations and entities inevitably have greater reach. (shrink)

Clarke and Beck import certain assumptions about the nature of numbers. Although these are widespread within research on number cognition, they are highly contentious among philosophers of mathematics. In this commentary, we isolate and critically evaluate one core assumption: the identity thesis.

One pressing question facing Barnes andWilliams is that of which vari- eties of metaphysical indeterminacy can be can accommodated within their framework. In what remains, I shall examine whether their framework can allow that it sometimes metaphysically indeterminate whether an object exists. I shall begin by outlining an argument, due to Theodore Sider, to the conclusion that vague existence is impossible.

This book is devoted to the reintroduction of the remarkable approach to sociological inquiry developed by Harvey Sacks. Sacks's original analyses - concerned with the lived detail of action and language-in-interaction, discoverable in members' actual activities - demonstrated a means of doing sociology that had previously seemed impossible. In so doing, Sacks provided for highly technical, detailed, yet stunningly simple solutions to some of the most trenchant troubles for the social sciences relating to language, culture, meaning, knowledge, action, and social (...) organisation. In this original collection, scholars working in a range of different fields, including sociology, human geography, communication and media studies, social psychology, and linguistics, outline the ways in which their work has been inspired, influenced, and shaped by Sacks's approach, as well as how their current research is taking Sacks's legacy forward in new directions. As such, the collection is intended to provide both an introduction to, and critical exploration of, the work of Harvey Sacks and its continued relevance for the analysis of contemporary society.

It has been suggested that the enterprise of developing mechanistic theories of the human cognitive architecture is flawed because the theories produced are not directly falsifiable. Newell attempted to sidestep this criticism by arguing for a Lakatosian model of scientific progress in which cognitive architectures should be understood as theories that develop over time. However, Newell's own candidate cognitive architecture adhered only loosely to Lakatosian principles. This paper reconsiders the role of falsification and the potential utility of Lakatosian principles in (...) the development of cognitive architectures. It is argued that a lack of direct falsifiability need not undermine the scientific development of a cognitive architecture if broadly Lakatosian principles are adopted. Moreover, it is demonstrated that the Lakatosian concepts of positive and negative heuristics for theory development and of general heuristic power offer methods for guiding the development of an architecture and for evaluating the contribution and potential of an architecture's research program.

In ‘Salvaging the Concept of Nudge’ Yashar Saghai performs an important clarificatory task which certainly advances our philosophical and ethical understanding of nudges in public policy, and in healthcare ethics in particular.1 In this brief commentary I identify some issues which could usefully be taken forward in subsequent discussions.A central difficulty with ethical discussions of nudging is that insufficient care is taken to distinguish two morally important features of nudges. The first, which Saghai very properly concentrates upon, is the mechanism (...) of nudging. Nudges rely on psychological properties of human decision-makers as the way in which their intended effects are brought about. Much of the ethical concern with nudges focuses on just this. Whatever the motive of the nudger, or the objective of the nudge, or the ex ante or ex post ratification of the nudge by the nudge, operating through influence, impulse or non-rational features of the nudgee's decision-making is wrong. The nature of this wrongness can be spelled out in different ways, and which one of these we choose has important implications for the precise ethical argument …. (shrink)

The evolution of nonconceptive sexuality in bonobos and chimpanzees is discussed from a functional perspective. Bonobos and chimpanzees have three functions of sexual activity in common (paternity confusion, practice sex, and exchange for favors), but only bonobos use sex purely for communication about social relationships. Bonobo hypersexuality appears closely linked to the evolution of female-female alliances. I suggest that these alliances were made possible by relaxed feeding competition, that they were favored through their effect on reducing sexual coercion, and that (...) they are ultimately responsible for the relaxed social conditions that allowed the evolution of “communication sex.”.

The sudden appearance in the fossil record of the major animal phyla apparently records a phase of unparalleled, rapid evolution at the base of the Cambrian period, 545 Myr ago. This has become known as the Cambrian evolutionary ‘explosion’, and has fuelled speculation about unique evolutionary processes operating at that time. The acceptance of the palaeontological evidence as a true reflection of the evolutionary narrative has been criticised in two ways: from a reappraisal of the phylogenetic relationships of the early (...) fossils, and from predicitions of molecular divergence times, based on six appropriate metazoan genes. Phylogenetic analysis of the arthropods implies an earlier, Precambrian history for most clades, and hence an extensive period of cladogenesis unrecorded by fossils. A similar argument can be applied to molluscs, lophophorates and deuterostomes. Molecular evidence implies divergence between clades to at least 1000 Myr ago. The apparent paradox between the sudden appearance of recognisable metazoans and their extended evolutionary history might be explained by a sudden Cambrian increase in body size, which was accompanied by skeletisation. A new paradigm suggests that the ‘explosion’ in the record may have been decoupled from the evolutionary innovation. (shrink)
