We characterize a type of functional explanation that addresses why a homologous trait originating deep in the evolutionary history of a group remains widespread and largely unchanged across the group’s lineages. We argue that biologists regularly provide this type of explanation when they attribute conserved functions to phenotypic and genetic traits. The concept of conserved function applies broadly to many biological domains, and we illustrate its importance using examples of molecular sequence alignments at the intersection of evolution and cell biology. (...) We use these examples to show how the study of conserved functions can integrate knowledge of a trait’s causal effects on fitness and its history of natural selection without invoking adaptation. We also show how conserved function provides a novel basis for addressing objections against evolutionary functions raised by Robert Cummins. (shrink)

When should you engage with difficult arguments against your cherished controversial beliefs? The primary conclusion of this book is that your obligations to engage with counterarguments are more limited than is often thought. In some standard situations, you shouldn't engage with difficult counterarguments and, if you do, you shouldn't engage with them open-mindedly. This conclusion runs counter to aspects of the Millian political tradition and political liberalism, as well as what people working in informal logic tend to say about argumentation. (...) -/- Not all misleading arguments wear their flaws on their sleeve. Each step of a misleading argument might seem compelling and you might not be able to figure out what's wrong with it. Still, even if you can't figure out what's wrong with an argument, you can know that it's misleading. One way to know that an argument is misleading is, counterintuitively, to lack expertise in the methods and evidence-types employed by the argument. When you know that a counterargument is misleading, you shouldn't engage with it open-mindedly and sometimes shouldn't engage with it at all. You shouldn't engage open-mindedly because you shouldn't be willing to reduce your confidence in response to arguments you know are misleading. And you sometimes shouldn't engage closed-mindedly, because to do so can be manipulative or ineffective. -/- In making this case, Jeremy Fantl discusses echo chambers and group polarization, the importance in academic writing of a sympathetic case for the opposition, the epistemology of disagreement, the account of open-mindedness, and invitations to problematic academic speakers.

Did Plato intend the laws of the Laws to change? While most scholars agree that there is to be legal change in Magnesia, I contend that this issue has been clouded by confusing three distinct questions: (1) whether there are legal mechanisms for changing the law in Magnesia, (2) what the attitudes of Magnesian citizens towards innovation and legal change are, and (3) whether Plato thinks the law is always the ultimate political authority. Once we separate these issues and look (...) at the relevant texts more closely, we see that the Athenian Visitor is primarily concerned with supplementing the original lawgiver’s laws and that any innovation that occurs should be consistent with this lawcode. This does not settle the question about whether it is always right to act in accordance with the existing laws, though it does provide a valuable framework for understanding a central aspect of Platonic political philosophy. Thus, although Plato’s ideal places knowledge above the law, in practice the laws of Magnesia will be fixed and authoritative for those people living under them. (shrink)

We discuss from a philosophical perspective the way in which the normal concept of time might be said to `emerge' in a quantum theory of gravity. After an introduction, we briefly discuss the notion of emergence, without regard to time. We then introduce the search for a quantum theory of gravity ; and review some general interpretative issues about space, time and matter. We then discuss the emergence of time in simple quantum geometrodynamics, and in the Euclidean approach. Section 6 (...) concludes. (shrink)

Abstract: This paper assesses the Everettian approach to the measurement problem, especially the version of that approach advocated by Simon Saunders and David Wallace. I emphasise conceptual, indeed metaphysical, aspects rather than technical ones; but I include an introductory exposition of decoherence. In particular, I discuss whether---as these authors maintain---it is acceptable to have no precise definition of 'branch' (in the Everettian kind of sense). (A version of this paper will appear in a CTNS/Vatican Observatory volume on Quantum Theory and (...) Divine Action, ed. Robert Russell et al.). (shrink)

In The Metaphysics of Truth, Doug Edwards offers a sustained case against deflationism about truth and in favour of his preferred pluralist theory of truth. Here, I take up three of the main components of that case. The first is Edwards' account of the distinctive metaphysical commitments of deflationism. His views about this issue have changed over the past few years, and I detail these changes as well as a concern for the views that he develops in the book. Second, (...) I take up the argument that Edwards offers for thinking that deflationism is, in a certain sense, internally unstable. I explain why this argument is inconclusive, outlining three responses to it on behalf of the deflationist. Third, I consider Edwards' novel argument for truth pluralism, which acts as an indirect argument against deflationism. After sorting out some interpretive nuances related to the use of definite descriptions in this argument, I show how the deflationist can resist it. Having responded to Edwards' critique of deflationism, I close by briefly explaining why I take the methodology of deflationism to be especially promising, insofar as it underscores the significance of empirically-informed inquiry about truth.

A general method of interpreting weak higher-type theories of nonstandard arithmetic in their standard counterparts is presented. In particular, this provides natural nonstandard conservative extensions of primitive recursive arithmetic, elementary recursive arithmetic, and polynomial-time computable arithmetic. A means of formalizing basic real analysis in such theories is sketched.

Most studies on climate change response have examined reductions in greenhouse gas (GHG) emissions. Yet these studies do not take into account ecosystem services constraints and biophysical disruptions wrought by climate change that may require broader types of response. By studying a firm in the wine industry and using a research approach not constrained by structured methodologies or biased toward GHG emissions, the findings suggest that both “inside out” and “outside in” actions are taken in response to climate change. While (...) attempts are made by the firm to curtail and reverse climate change through management of carbon emissions, evidence suggests a clear pattern of actions designed to adjust to the adverse consequences of climate change as well. The results both confirm and extend previous findings and suggest that the level and breadth of response to climate change is shaped by situated attention, structural controls, and industry type.

This book offers a distinctive treatment of Hayek's ideas as a "research program". It presents a detailed account of aspects of Hayek's intellectual development and of problems that arise within his work, and then offers some broad suggestions as to ways in which the program initiated in his work might be developed further. The book discusses how Popper and Lakatos' ideas about "research programs" might be applied within political theory. There then follows a distinctive presentation of Hayek's intellectual development up (...) to The Road to Serfdom, together with critical engagement with his later ideas. The discussion draws on a full range of his writings, makes use of some neglected earlier work on social theory and law, and also draws on archival material. This book should appeal to anyone with an interest in Hayek's work, as well as to those with a concern for twentieth century intellectual history. (shrink)

In Section 2, I survey some of the ways that computers are used in mathematics. These raise questions that seem to have a generally epistemological character, although they do not fall squarely under a traditional philosophical purview. The goal of this article is to try to articulate some of these questions more clearly, and assess the philosophical methods that may be brought to bear. In Section 3, I note that most of the issues can be classified under two headings: some (...) deal with the ability of computers to deliver appropriate “evidence” for mathematical assertions, a notion that is explored in Section 4, while others deal with the ability of computers to deliver appropriate mathematical “understanding,” a notion that is considered in Section 5. Final thoughts are provided in Section 6. (shrink)

This chapter addresses concerns that pragmatic encroachers are committed to problematic knowledge variance. It first replies to Charity Anderson and John Hawthorne’s new putative problem cases, which purport to show that pragmatic encroachment is committed to problematic variations in knowledge depending on what choices are available to the potential knower. It argues that the new cases do not provide any new reasons to be concerned about the pragmatic encroacher’s commitment to knowledge-variance. The chapter further argues that concerns about knowledge-variance are (...) not limited to the pragmatic encroacher, but come up for traditional purist invariantism as well. (shrink)

"Robert Brandom" is one of the most significant philosophers writing today, yet paradoxically philosophers have found it difficult to get to grips with the details and implications of his work. This book aims to facilitate critical engagement with Brandom's ideas by providing an accessible overview of Brandom's project and the context for an initial assessment. Jeremy Wanderer's examination focuses on Brandom's inferentialist conception of rationality, and the core part of this conception that aims to specify the structure that a (...) set of performances within a social practice must have for the participants to count as sapient beings by virtue of their participation in the practice, and for the performances within the practice to have objective semantic content by virtue of their featuring within the practice. Wanderer's exploration of these two goals forms the structure to the book. It Includes: Part I that provides a structural model of linguistic practice and considers various groups of potential participants in terms of their relationships to this practice; and, Part II that examines the meaning of the performances that are caught up in this gameplaying practice. Brandom's approach to semantics is outlined and the challenge such an approach has in allowing for a representational dimension of language and thought is explored. Wanderer offers readers a valuable framework for understanding the Brandomian system and helps situate Brandom's systematic theorizing within contemporary Anglo-American philosophy. This book will be a sought after aid to reading Brandom for advanced students and philosophers engaging with his challenging body of work. (shrink)

In _Nonsense upon Stilts¸_ first published in 1987, Waldron includes and discusses extracts from three classic critiques of the idea of natural rights embodied in the 1789 Declaration of the Rights of Man and the Citizen. Each text is prefaced by an historical introduction and an analysis of its main themes. The collection as a whole in introduced with an essay tracing the philosophical background to the three critiques as well as the eighteenth-century idea of natural rights which they attacked. (...) But the point of reproducing these works is not merely historical. Modern attacks on ‘rights-based’ political philosophy mirror the concerns of Bentham, Burke and Marx. Jeremy Waldron has therefore added an extensive concluding essay which relates these classic texts to the modern discussion of rights and re-examines the idea of rights in the light of contemporary critiques. This text provides an invaluable teaching tool for courses in politics and philosophy. (shrink)

The possibility of error conditions the possibility of normative principles. I argue that extant interpretations of this condition undermine the possibility of normative principles for our action because they implicitly treat error as a perfection of an action. I then explain how a constitutivist metaphysics of capacities explains why error is an imperfection of an action. Finally, I describe and defend the interpretation of the error condition which follows.

Is there anything in the mind that was not first in the senses? According to the received view, the French empiricist Étienne Bonnot de Condillac’s answer to this was a firm “No”. Unlike Locke, who accepted the existence of innate faculties, Condillac rejected the existence of all innate structure and instinctive behaviours. Everything, therefore, is learned. In this article, I argue that from at least the writing of his 1754 Traité des sensations, this reading fails to capture the true nature (...) of his philosophy of mind. I present a genetic reading of Condillac’s philosophy that shows that from the 1750s until his death in 1780, he developed, by engaging closely with the life sciences of his day, an increasingly sophisticated understanding of the mind and perception. This understanding depends on the acceptance of the activity of the mind, innate structure, and a moderate defence of instincts—all characteristics of the mind that he is most commonly read as rejecting. Reading Condillac in this genetic way demonstrates that his philosophy of mind is much more original and powerful than has previously been recognised. (shrink)

This paper gives a technically elementary treatment of some aspects of Hamilton -Jacobi theory, especially in relation to the calculus of variations.

Issues pertaining to sex and gender continue to be some of the most hotly debated topics of our time. While many of the most heated disputes occur at the level of politics and public policy, metaphysics, too, has a crucial role to play in these debates. In this essay, I explore several key metaphysical debates concerning sex and gender through the lenses of two important areas in contemporary metaphysics: the metaphysics of essence and the ontology of the human person. The (...) goal here is not to advocate any particular position on these issues, but to show how the tools of contemporary metaphysics can help to offer a more comprehensive map of the conceptual terrain, indicating where major areas of agreement can be found and where the most important disagreements really lie.

According to Michael Friedman, Ernst Cassirer’s “outstanding contribution [to Neo-Kantianism] was to articulate, for the first time, a clear and coherent conception of formal logic within the context of the Marburg School” (Friedman 2000, p. 30). In his paper “Kant und die moderne Mathematik” (1907), Cassirer argued not only that the new relational logic of Frege1 and Russell was a major breakthrough with profound philosophical implications, but also that the logicist thesis itself was a “fact” of modern mathematics. Cassirer summarizes (...) his evaluation of Russell’s work: Here logic and mathematics have been fused into a true, henceforth indissoluble unity; and from this inner connection there arises for each...

This paper asks how we should regard the laws and customs of armed conflict, and specifically the rule prohibiting the targeting of civilians. What view should we take of the moral character and significance of such rules? Some philosophers have suggested that they are best regarded as useful conventions. This view is sometimes motivated by a "deep moral critique" of the rule protecting civilians: Jeff McMahan believes for example that the existing rules protect some who ought to be liable to (...) attack (on account of their having voluntarily contributed to the injustice or aggression being resisted). He thinks we would be better off with a different principle of discrimination in warfare. But McMahan acknowledges that for the time being we must stick with the rules that we have. The present paper does five things: (1) it explores and takes further some of McMahan's insights about the importance of existing positive law in this area; (2) it argues that some of the features that philosophers find problematic with the rule offering blanket protection to all civilians have to do with administrability; (3) it raises some questions about whether the rule protecting civilians can really be regarded as a convention (and it argues that certainly it cannot be regarded as a "Lewis-convention" in a strict sense); (4) to the extent that the rule can be regarded as conventional, the paper argues that it remains a deadly serious moral rule, partly because of the circumstances of death and destruction in which it operates and which it tries to ameliorate, and partly on account of its fragility. The fifth point is the most important. (5) The rule protecting civilians does not operate in circumstances in which, apart form positive law, civilians like everyone would be liable to attack. The rule operates against a moral background in which all deliberate killing is to be regarded as murder; some deliberate killings (of combatants) are privileged in warfare; but the rule about civilians reflects the fact that this is a strictly limited privilege and that those who target civilians do not get the benefit of it. Changing our view of the default position in this way enables us to better understand the distinctive work that this rule does. (shrink)

In this article I discuss what I am calling “ally aesthetics.” I suggest a set of necessary, though not necessarily sufficient, considerations for the creation of successful instances of ally art. Focusing on three case studies, I propose some key characteristics of ally aesthetics, such as its contextual/temporal nature and how that relates to success and the importance of understanding the place of the ally aesthetic within the larger movements they are allying with.

Introduction, by C.K. Ogden.--The theory of fictions, by Jeremy Bentham.

Commentators have often been puzzled by the structure of the _Symposium_; in particular, it is unclear what the relationship is between Socrates’ speech and that of the other symposiasts. This chapter seeks to make a contribution to that debate by highlighting parallels between the first four speeches of the _Symposium_ and the goals of the early education in the Republic. In both dialogues, I contend, we see Plato concerned with educating people through (a) activating and cultivating spirited motivations, (b) becoming (...) lawful and taking virtue as a goal, (c) harmonizing the opposing forces in their soul, and (d) minimizing the appetites and making them orderly. While these are familiar points from the moral education of the Republic, I argue that they also map onto the first four speeches of the _Symposium_ respectively. Because in the _Republic_ this moral education is necessary to make progress on the epistemic ascent, we can speculate that there is a similar point to be made in the _Symposium_ – without first training our character adequately, we will not be able to climb the ladder of love. While the positive effects of Eros described in the early speeches of the _Symposium_ are only imitations of the ideal education regime of Kallipolis, they nevertheless improve one’s character in such a way that better prepares the soul for philosophy. Finally, I argue that the importance of this moral education is dramatized at the end of the _Symposium_ through Agathon’s amicable refutation by Socrates on the one hand, and the drunken entrance of Alcibiades on the other. Agathon shows potential for philosophy whereas Alcibiades is the exemplar of what happens when somebody comes to philosophy without a harmonized soul. (shrink)

As idealized descriptions of mathematical language, there is a sense in which formal systems specify too little, and there is a sense in which they specify too much. On the one hand, formal languages fail to account for a number of features of informal mathematical language that are essential to the communicative and inferential goals of the subject. On the other hand, many of these features are independent of the choice of a formal foundation, so grounding their analysis on a (...) particular choice of a formal system introduces unnecessary specificity. This chapter begins to map out the design features of mathematical language without descending to the level of formal implementation, drawing on examples from the mathematical literature and insights from the design of computational proof assistants and their libraries.

Many response-dependence theorists equate moral truth with the generation of some affective psychological response: what makes this action wrong, as opposed to right, is that it would cause (or merit) affective response of type R (perhaps under ideal conditions). Since our affective nature is purely contingent, and not necessarily shared by all rational creatures (or even by all humans), response-dependence threatens to lead to relativism. In this paper, I will argue that emotional responses and moral features do not align in (...) the way predicted by the response-dependence theorist who wishes to tie morality to emotional affect. I further argue that since response-dependence accounts that tie morality to any sort of affect (be it an emotion, a desire, a desire to desire, or so on) cannot explain the objectivity and universality of morality; and since we do not need a psychological response to play a truth-constituting role in morality in order to explain the normativity or content of morality, we should reject such response-dependence accounts.

We want to propose a conception of wisdom with a view to exploring what insights it can give us into some basic dimensions of teaching in contemporary higher education. We hope to show that this conception allows us, on the one hand, to see some crucial inadequacies of existing approaches to critical thinking, multiculturalism, and global awareness or internationalism. On the other hand, we believe that it also gives us some insight into the existentially or spiritually meaningful dimensions of learning. (...) In this way, it bridges the most contemporary and practical foci of teaching and its most fundamental and timeless concerns. In the later part of the paper, we shall explore some of the characteristics of this conception further through the teachings of some of the longstanding wisdom traditions, including what they say about teaching itself.

In his Jerusalem, Moses Mendelssohn describes a Polynesian visitor to Dessau before traveling to India by way of ancient Jerusalem. In two pages, Mendelssohn has crossed the world, doing so to argue that in spite of their cultural differences, most human beings ultimately share basic salvific religious truths.

Both metaethicists and Kant scholars alike use the phrase ‘Kantian constructivism’ to refer to a kind of austere constructivism that holds that substantive ethical conclusions can be derived from the practical standpoint of rational agency as such. I argue that this widespread understanding of Kant is incompatible with Kant’s claim that the Categorical Imperative is a synthetic a priori practical judgement. Taking this claim about the syntheticity of the Categorical Imperative seriously implies that moral judgements follow from extra-logical but necessary (...) principles. These principles have to do not with the laws of practical thinking but the laws of practical thought about an object. I conclude that historical Kant was not what has come to be called a ‘Kantian constructivist’. (shrink)

We explore three types of criticisms of our theory on the development of children's social understanding. We reject suggestions that we offer nothing new to traditional theories of development or recent “social” accounts of “theory of mind.” Second, we take the point that there are grounds for improving our account of dyadic interaction in infancy but reject claims that we have not sufficiently accounted for how we incorporate the notions of criteria and structure into the theory. Third, we accept that (...) the epistemic triangle, as defined, would benefit from an affective dimension and such a formulation could be used to describe the dynamic of developmental change from infancy to beyond early childhood. We still feel that the combination of Wittgenstein, Vygotsky, and Piaget remains as an antidote to the flaws in current “theories of mind” approaches to social understanding. (shrink)
