Standard Type Theory, STT, tells us that b^n(a^m) is well-formed iff n=m+1. However, Linnebo and Rayo have advocated the use of Cumulative Type Theory, CTT, has more relaxed type-restrictions: according to CTT, b^β(a^α) is well-formed iff β > α. In this paper, we set ourselves against CTT. We begin our case by arguing against Linnebo and Rayo’s claim that CTT sheds new philosophical light on set theory. We then argue that, while CTT ’s type-restrictions are unjustifiable, the type-restrictions imposed by (...) STT are justified by a Fregean semantics. What is more, this Fregean semantics provides us with a principled way to resist Linnebo and Rayo’s Semantic Argument for CTT. We end by examining an alternative approach to cumulative types due to Florio and Jones; we argue that their theory is best seen as a misleadingly formulated version of STT. (shrink)

This booklet is a Korean adaptation and translation of Part VIII of forall x: Calgary (Fall 2021 edition), which is intended to be introductory material for modal logic. The original text is based on Robert Trueman's A Modal Logic Primer, which is revised and expanded by Richard Zach and Aaron Thomas-Bolduc in forall x: Calgary. (forall x: Calgary is based on forall x: Cambridge by Tim Button, which is in turn based on forall x by P. D. Magnus, (...) and also includes material from forall x: Lorain County Remix by Cathal Woods and J. Robert Loftis.) This booklet is licensed under a Creative Commons Attribution 4.0 license. (shrink)

Universals are putative objects like wisdom, morality, redness, etc. Although we believe in properties (which, we argue, are not a kind of object), we do not believe in universals. However, a number of ordinary, natural language constructions seem to commit us to their existence. In this paper, we provide a fictionalist theory of universals, which allows us to speak as if universals existed, whilst denying that any really do.

forall x: Calgary is a full-featured textbook on formal logic. It covers key notions of logic such as consequence and validity of arguments, the syntax of truth-functional propositional logic TFL and truth-table semantics, the syntax of first-order (predicate) logic FOL with identity (first-order interpretations), symbolizing English in TFL and FOL, and Fitch-style natural deduction proof systems for both TFL and FOL. It also deals with some advanced topics such as modal logic, soundness, and functional completeness. Exercises with solutions are available. (...) It is provided in PDF (for screen reading, printing, and a special version for dyslexics), HTML, and in LaTeX source code. (shrink)

This is a review of "Properties and Propositions: The Metaphysics of Higher-Order Logic" by Robert Trueman. Following an overview of the main themes of the book, I discuss the metaphysical presuppositions of Trueman's Fregean notation for predicate abstraction and evaluate his argument for strict typing.

This chapter examines two ways in which liberal thinkers have appealed to claims about disagreement in order to defend a principle of free speech. One argument, from Mill, says that free speech is a necessary condition for healthy disagreement, and that healthy disagreement is conducive to human flourishing. The other argument says that in a community of people who disagree about questions of value, free speech is a necessary condition of legitimate democratic government. We argue that both of these arguments, (...) in their standard guises, are premised upon contestable views about the realpolitik of disagreement in a liberal society. (shrink)

In the era of “big data,” science is increasingly information driven, and the potential for computers to store, manage, and integrate massive amounts of data has given rise to such new disciplinary fields as biomedical informatics. Applied ontology offers a strategy for the organization of scientific information in computer-tractable form, drawing on concepts not only from computer and information science but also from linguistics, logic, and philosophy. This book provides an introduction to the field of applied ontology that is of (...) particular relevance to biomedicine, covering theoretical components of ontologies, best practices for ontology design, and examples of biomedical ontologies in use. After defining an ontology as a representation of the types of entities in a given domain, the book distinguishes between different kinds of ontologies and taxonomies, and shows how applied ontology draws on more traditional ideas from metaphysics. It presents the core features of the Basic Formal Ontology (BFO), now used by over one hundred ontology projects around the world, and offers examples of domain ontologies that utilize BFO. The book also describes Web Ontology Language (OWL), a common framework for Semantic Web technologies. Throughout, the book provides concrete recommendations for the design and construction of domain ontologies. (shrink)

Wenn Präsident Kennedy nicht erschossen worden wäre, hätte er dann Nordvietnam bombardiert? Das weiß Gott allein. Oder doch nicht? Weiß wenigstens Er, was Kennedy getan hätte? ...

Nicht dadurch, daß Er menschliche Handlungen kausal determiniert, (...) wie die Dominikaner geglaubt zu haben scheinen , sondern indem Er Umstände herbeiführt, von denen Er weiß, daß wir in ihnen freiwillig Seinen Plänen entsprechend handeln werden.

The distinction between the regulative (‘practical’, ‘subjective’, ‘decision-procedural’) and the theoretical (‘objective’, ‘absolute’) pertains to the aims (the desiderata) of an account of justification. This distinction began in ethics and spread to epistemology. Each of internalism, externalism, is separately forced to draw this distinction to avoid a stock, otherwise fatal, argument levelled against them by the other. Given this situation however, we may finesse much partisan conflict in epistemology by simply seeing differing accounts of justification as answering to radically distinct (...) desiderata of adequacy. We should see knowledge as answering to the theoretical desideratum of adequacy alone; and rationality as answering to the regulative desideratum of adequacy alone. Objections to this ‘Gordian’ [knot] approach to epistemology (from virtues theorists and others) are rejected. Such an approach may make for accounts that violate our ordinary language intuitions; but in developing an epistemological axiology, any such intuitions are not to the point. (shrink)

Numerous research groups are now utilizing Basic Formal Ontology as an upper-level framework to assist in the organization and integration of biomedical information. This paper provides elucidation of the three existing BFO subcategories of realizable entity, namely function, role, and disposition. It proposes one further sub-category of tendency, and considers the merits of recognizing two sub-categories of function for domain ontologies, namely, artifactual and biological function. The motivation is to help advance the coherent ontological treatment of functions, roles, and dispositions, (...) to help provide the potential for more detailed classification, and to shed light on BFO’s general make-up and use.

The epistemic poverty objection is commonly levelled by externalists against deontological conceptions of epistemic justification. This is that an “oughts” based account of epistemic justification together with “ought” implies “can” must lead us to hold to be justified, epistemic agents who are objectively not truth-conducive cognizers. The epistemic poverty objection has led to a common response from deontologists, namely to embrace accounts of bounded rationality—subjective, practical or regulative accounts rather than objective, absolute or theoretical accounts. But the bounds deontological epistemologists (...) and their opponents entertain rarely include cultural limitations. This paper considers neo-Vygotskian arguments that we must consider such cultural limits in defending deontologism, and thus that any deontologically motivated perspectivism must be in part a cultural perspectivism. The dangers of strong relativism are flagged and an attempt is made to steer a.. (shrink)

This paper identifies and criticizes certain fundamental commitments of virtue theories in epistemology. A basic question for virtues approaches is whether they represent a ‘third force’––a different source of normativity to internalism and externalism. Virtues approaches so-conceived are opposed. It is argued that virtues theories offer us nothing that can unify the internalist and externalist sub-components of their preferred success-state. Claims that character can unify a virtues-based axiology are overturned. Problems with the pluralism of virtues theories are identified––problems with pluralism (...) and the nature of the self; and problems with pluralism and the goals of epistemology. Moral objections to virtue theory are identified––specifically, both the idea that there can be a radical axiological priority to character and the anti-enlightenment tendencies in virtues approaches. Finally, some strengths to virtue theory are conceded, while the role of epistemic luck is identified as an important topic for future work. (shrink)

This paper argues that self-deception cannot be explained without employing a depth-psychological ("psychodynamic") notion of the unconscious, and therefore that mainstream academic psychology must make space for such approaches. The paper begins by explicating the notion of a dynamic unconscious. Then a brief account is given of the "paradoxes" of self-deception. It is shown that a depth-psychological self of parts and subceptive agency removes any such paradoxes. Next, several competing accounts of self-deception are considered: an attentional account, a constructivist account, (...) and a neo-Sartrean account. Such accounts are shown to face a general dilemma: either they are able only to explain unmotivated errors of self-perception--in which case they are inadequate for their intended purpose--or they are able to explain motivated self-deception, but do so only by being instantiation mechanisms for depth-psychological processes. The major challenge to this argument comes from the claim that self-deception has a "logic" different to other-deception--the position of Alfred Mele. In an extended discussion it is shown that any such account is explanatorily adequate only for some cases of self-deception--not by any means all. Concluding remarks leave open to further empirical work the scope and importance of depth-psychological approaches. (shrink)

Material traces of the past are notoriously inscrutable; they rarely speak with one voice, and what they say is never unmediated. They stand as evidence only given a rich scaffolding of interpretation which is, itself, always open to challenge and revision. And yet archaeological evidence has dramatically expanded what we know of the cultural past, sometimes demonstrating a striking capacity to disrupt settled assumptions. The questions we address in Evidential Reasoning are: How are these successes realized? What gives us confidence (...) in the credibility and robustness, the trustworthiness, of the evidential claims based on archaeological data? And, what constitute best practices in building evidential claims, critically scrutinizing them and putting them to work in archaeological contexts? Rather than retreat to abstractions about how how science operates in the ideal, we approach this question by interrogating a number of close-to-the-ground case studies with the aim of teasing out the wisdom embodied in archaeological practice. The cases we consider – of fieldwork, strategies for working with old evidence, and the role of external resources – illuminate the role of various types of inferential scaffolding and bring into focus practice-grounded epistemic norms that we believe serve archaeologists better than the all-or-nothing ideals of truth and objectivity that dominate programmatic debate.

Eliminativism was targeted by transcendental arguments from the first. Three responses to these arguments have emerged from the eliminativist literature, the heart of which is that such arguments are question-begging. These responses are shown to be incompatible with the position, eliminativism, they are meant to defend. Out of these failed responses is developed a general transcendental argument against eliminativism (the "Paradox of Abandonment"). Eliminativists have anticipated this argument, but their six different attempts to counter it are shown to be separately (...) inadequate, mutually incompatible, and, again, incompatible with the position that they are seeking to defend.

Three recent ‘state of the art’ Frankfurt cases are responded to: Widerker’s Brain-Malfunction-W case and Pereboom’s Tax Evasion cases (2 & 3). These cases are intended by their authors to resurrect the neo-Frankfurt project of overturning the Principle of Alternative Possibilities (PAP) in the teeth of the widespread acceptance of some combination of the WKG (Widerker-Kane-Ginet) dilemma, the Flicker of Freedom strategy and the revised PAP response (‘Principle of Alternative Blame’, ‘Principle of Alternative Expectations’). The three neo-Frankfurt cases of Pereboom (...) and Widerker shown to be insufficient for their intended purpose. Of central importance to any account of responsibility is that this applies at the level of the Right and not the Good. Arguments of Carlos Moya are expanded and augmented by considerations from Chisholm, Lucas, Dummett and Lockie (2003) to show that a number of severe problems remain for anyone attempting to resurrect the Frankfurt project.

The paper begins by drawing a number of ‘levels’ distinctions in epistemology. It notes that a theory of knowledge must be an attempt to obtain knowledge . It is suggested that we can make sense of much of the work found in analytic theory of knowledge by seeing three framework assumptions as underpinning this work. First, that to have philosophical knowledge of knowledge requires us to have an analysis. Second, that much of what we require from a theory of knowledge (...) may be obtained by developing such analyses of first-order, concrete, empirical, propositional knowledge. Third, that the final arbiter of the correctness of such analyses is to be the carefully examined intuitions of the epistemologist. The paper attacks each aspect of this framework on the ground that this methodology will precisely not give us knowledge . In passing, comparisons are drawn with arguments that led to the demise of phenomenalism. The paper concludes with remarks about realism/anti-realism and consensus/disagreement in analytic epistemology. The paper recommends that we seek to develop theories of knowledge rather than analyses, and defends the position that such theories will precisely not be analyses. (shrink)

Moral Internalism is the claim that it is a priori that moral beliefs are reasons for action. At least three conceptions of 'reason' may be disambiguated: psychological, epistemological, and purely ethical. The first two conceptions of Internalism are false on conceptual, and indeed empirical, grounds. On a purely ethical conception of 'reasons', the claim is true but is an Externalist claim. Positive arguments for Internalism — from phenomenology, connection and oddness — are found wanting. Three possible responses to the stock (...) Externalist objections are uncovered and overturned. In so doing a close relation between Internalism and Behaviourism is revealed, and some stock anti-behaviouristic arguments are co-opted for Externalism. The likely dependence of Internalism on an Atomistic Associationism is uncovered and criticised. Internalism is seen as being ultimately a type of Ethical Determinism. Finally, a sketch of an Anti-Associative Externalism is given whereby the notion of self determination of action is put forward as an account of moral motivation fit to resist both the internalist and the belief-desire psychology premises of the stock non-cognitivist argument.

There are two basic views concerning the relationship between constitutional rights and proportionality analysis. The first maintains that there exists a necessary connection between constitutional rights and proportionality, the second argues that the question of whether constitutional rights and proportionality are connected depends on what the framers of the constitution have actually decided, that is, on positive law. The first thesis may be termed ‘necessity thesis’, the second ‘contingency thesis’. According to the necessity thesis, the legitimacy of proportionality analysis is (...) a question of the nature of constitutional rights, according to the contingency thesis, it is a question of interpretation. The article defends the necessity thesis. | A previous version of this article was published in Chinese Yearbook of Constitutional Law, Vol. 2010, 221–235. (shrink)

Where does the mind begin and end? Most philosophers and cognitive scientists take the view that the mind is bounded by the skull or skin of the individual. Robert Wilson, in this provocative and challenging 2004 book, provides the foundations for the view that the mind extends beyond the boundary of the individual. The approach adopted offers a unique blend of traditional philosophical analysis, cognitive science, and the history of psychology and the human sciences. The companion volume, Genes and (...) the Agents of Life, explores the theme in the biological sciences. Written with verve and clarity, this ambitious book will appeal to a broad swathe of professionals and students in philosophy, psychology, cognitive science, and the history of the behavioural and human sciences.

In Pascal Boyer’s book Religion Explained inference systems are made to do a lot of work in his attempts to explain cognition in religion. These inference systems are systems in the brain that produces inferences when they are activated by things we perceive in our environment. According to Boyer they perceive things, produce explanations, and perform calculations. However, if Wittgenstein’s observation, that “only of a living human being and what resembles (behaves like) a living human being can one say: it (...) has sensations; it sees; is blind; hears; is deaf; is conscious or unconscious” is correct then it seems that Boyer’s talk of inference systems perceiving and inferring is confused.

Trope theory is an increasingly prominent contender in contemporary debates about the existence and nature of properties. But it suffers from ambiguity concerning the nature of a trope. Disambiguation reveals two fundamentally different concepts of a trope: modifier tropes and module tropes. These types of tropes are unequally suited for metaphysical work. Modifier tropes have advantages concerning powers, relations, and fundamental determinables, whereas module tropes have advantages concerning perception, causation, character-grounding, and the ontology of substance. Thus, the choice between modifier (...) tropes and module tropes is significant and divides the advantages of trope theory simpliciter. In addition, each resulting trope theory is unstable: modifier trope theory threatens to collapse into realism and module trope theory threatens to collapse into austere nominalism. This invites reflection on the stability of trope theory in general. (shrink)

This paper develops a version of the self-refutation argument against relativism in the teeth of the prevailing response by relativists: that this argument begs the question against them. It is maintained that although weaker varieties of relativism are not self-refuting, strong varieties are faced by this argument with a choice between making themselves absolute (one thing is absolutely true - relativism); or reflexive (relativism is 'true for' the relativist). These positions are in direct conflict. The commonest response, Reflexive Relativism, is (...) shown to be vulnerable to an iterated version of the self-refutation argument. As a result, Reflexive Relativism possesses only the appearance of content, being either incoherent, or a regressively disguised version of Absolute Relativism. Concluding remarks on Absolute Relativism acknowledge this to be a bare, formal possibility, but claim that in fact it must represent one of a range of weaker varieties of relativism that alone remain tenable.

Is testimony a legitimate source of aesthetic belief? Can I, for instance, learn that a film is excellent on your say-so? Optimists say yes, pessimists no. But pessimism comes in two forms. One claims that testimony is not a legitimate source of aesthetic belief because it cannot yield aesthetic knowledge. The other accepts that testimony can be a source of aesthetic knowledge, yet insists that some further norm prohibits us from exploiting that resource. I argue that this second form of (...) pessimism has certain advantages over the first. I offer two candidates for the non-epistemic norm that, on this view, stands in the way of our taking aesthetic testimony. And I argue that this form of pessimism meets a challenge to pessimism in general – that of explaining why, if testimony cannot be a legitimate source of aesthetic belief, we can nonetheless rightly rely on the aesthetic recommendations of others.

This paper explains how the practice of ‘no platforming’ can be reconciled with a liberal politics. While opponents say that no platforming flouts ideals of open public discourse, and defenders see it as a justifiable harm-prevention measure, both sides mistakenly treat the debate like a run-of-the-mill free speech conflict, rather than an issue of academic freedom specifically. Content-based restrictions on speech in universities are ubiquitous. And this is no affront to a liberal conception of academic freedom, whose purpose isn’t just (...) to protect the speech of academics, but also to give them the prerogative to determine which views and speakers have sufficient disciplinary credentials to receive a hearing in academic contexts. No platforming should therefore be acceptable to liberals, in principle, in cases where it is used to support a university culture that maintains rigorous disciplinary standards, by denying attention and credibility to speakers without appropriate disciplinary credentials.

Contemporary republicanism is characterized by three main ideas: free persons, who are not subject to the arbitrary power of others; free states, which try to protect their citizens from such power without exercising it themselves; and vigilant citizenship, as a means to limit states to their protective role. This book advances an economic model of such republicanism that is ideologically centre-left. It demands an exit-oriented state interventionism, one that would require an activist government to enhance competition and resource exit from (...) dominating relationships within markets of all types, be they marital, labour, or residential. The substantial intervention and redistribution necessitated by such an approach make it leftist, while its tendency to work with rather than against the grain of markets makes it centrist. It is, in short, a contribution to progressive republican political thought, but one that is less social-democratic than market-democratic in character. (shrink)

We respond to Stephen T. Davis’ criticism of our earlier essay, “Assessing the Resurrection Hypothesis.” We argue that the Standard Model of physics is relevant and decisive in establishing the implausibility and low explanatory power of the Resurrection hypothesis. We also argue that the laws of physics have entailments regarding God and the supernatural and, against Alvin Plantinga, that these same laws lack the proviso “no agent supernaturally interferes.” Finally, we offer Bayesian arguments for the Legend hypothesis and against the (...) Resurrection hypothesis. (shrink)

Moral luck occurs when factors beyond an agent’s control positively affect how much praise or blame she deserves. Kinds of moral luck are differentiated by the source of lack of control such as the results of her actions, the circumstances in which she finds herself, and the way in which she is constituted. Many philosophers accept the existence of some of these kinds of moral luck but not others, because, in their view, the existence of only some of them would (...) make morality unfair. I, however, argue that this intermediary approach is unstable, because either morality is fair in ways that rule out resultant, circumstantial, and constitutive moral luck (and this leads to moral responsibility skepticism), or morality is unfair in ways that permit the existence of those kinds of moral luck. Thus, such intermediary approaches lack the motivation that their proponents have long taken them to have. In the appendix, I point to ways in which morality is unfair concerning the scope of moral responsibility, moral obligation, moral taint, being a good or bad person, and flourishing. (shrink)

Permissivism says that for some propositions and bodies of evidence, there is more than one rationally permissible doxastic attitude that can be taken towards that proposition given the evidence. Some critics of this view argue that it condones, as rationally acceptable, sets of attitudes that manifest an untenable kind of arbitrariness. I begin by providing a new and more detailed explication of what this alleged arbitrariness consists in. I then explain why Miriam Schoenfield’s prima facie promising attempt to answer the (...) Arbitrariness Objection, by appealing to the role of epistemic standards in rational belief formation, fails to resolve the problem. Schoenfield’s strategy is, however, a useful one, and I go on to explain how an alternative form of the standards-based approach to Permissivism – one that emphasizes the significance of the relationship between people’s cognitive abilities and the epistemic standards that they employ – can respond to the arbitrariness objection.

Analytic theories of knowledge have traditionally maintained that the provenance of a true belief is critically important to deciding whether it is knowledge. However, a comparably widespread view is that it is our beliefs alone, regardless of their (potentially dubious) provenance which feature in psychological explanation, including the explanation of action: thus, that knowledge itself and as such is irrelevant in psychological explanation. The paper gives initial reasons why the ‘beliefs alone’ view of explanation should be resisted—arguments deriving ultimately from (...) the Meno indicate that the provenance of a true belief may be relevant to the explanation of action. However, closer scrutiny of these arguments shows that they are incapable of according provenance anything like as central a role in action explanation as provenance has traditionally been given in the theory of knowledge. A consideration of the history of science suggests anyway that all knowledge has a compromised provenance if one looks back any significant distance. It is concluded that the importance of the provenance of our beliefs is something that has been seriously over-emphasised in epistemology. (shrink)

There is a largely unrecognized ambiguity concerning the nature of a trope. Disambiguation throws into relief two fundamentally different conceptions of a trope and provides two ways to understand and develop each metaphysical theory that put tropes to use. In this paper I consider the relative merits that result from differences concerning a trope’s ability to ground the character of ordinary objects. I argue that on each conception of a trope, there are unique implications and challenges concerning character-grounding.

Nicomachean Ethics/NE, Book III, Chapters 1-5, provides Aristotle’s account of “Voluntary Movement.” It, thus, draws the Passion-Action distinction, only posited earlier in Categories, while also serving as the linchpin of NE’ discussion of Virtue, in explicitly connecting it to Right Reason. My explication of this text renders its terminology consistent with the Law of Excluded Middle and rebuts two criticisms of the Eudaimonistic Axiology on which it is based. These results are shown to be entailments of Aristotle’s doctrine that Voluntary (...) is (a) Relative. That categorization is then used to help treat a problematic case of Deliberation beyond his purview. (shrink)

A common compatibilist view says that we are free and morally responsible in virtue of the ability to respond aptly to reasons. Many hold a version of this view despite disagreement about whether free will requires the ability to do otherwise. The canonical version of this view is reductive. It reduces the pertinent ability to a set of modal properties that are more obviously compatible with determinism, like dispositions. I argue that this and any reductive view of abilities faces a (...) significant challenge: it cannot adequately explain the freedom-grounding element of this ability. The problem has the form of a dilemma. This leaves reasons-responsive compatibilists with two options: abandon theories of free will grounded in abilities or abandon reductive theories of abilities.

Discussions of whistleblowing and employee loyalty usually assume either that the concept of loyalty is irrelevant to the issue or, more commonly, that whistleblowing involves a moral choice in which the loyalty that an employee owes an employer comes to be pitted against the employee''s responsibility to serve public interest. I argue that both these views are mistaken and propose a third view which sees whistleblowing as entirely compatible with employee loyalty.

ABSTRACT According to edenic idealism, our ordinary object terms refer to items in the manifest world—the world of primitive objects and properties presented in experience. I motivate edenic idealism as a response to scenarios where it is difficult to match the objects in experience with corresponding items in the external world. I argue that edenic idealism has important semantic advantages over realism: it is the most intuitive view of what we are actually talking about when we use terms for objects.

Some scientific explanations appear to turn on pure mathematical claims. The enhanced indispensability argument appeals to these ‘mathematical explanations’ in support of mathematical platonism. I argue that the success of this argument rests on the claim that mathematical explanations locate pure mathematical facts on which their physical explananda depend, and that any account of mathematical explanation that supports this claim fails to provide an adequate understanding of mathematical explanation.

This paper makes the case for arms control regimes to govern the development and deployment of autonomous weapon systems and long range uninhabited aerial vehicles.

Bracket out the wrong of committing a wrong, or conspiring or colluding or conniving with others in their committing one. Suppose you have done none of those things, and you find yourself merely benefiting from a wrong committed wholly by someone else. What, if anything, is wrong with that? What, if any, duties follow from it? If straightforward restitution were possible — if you could just ‘give back’ what you received as a result of the wrongdoing to its rightful owner (...) — then matters are morally more straightforward. But in real-world cases that is often impossible, and questions of ‘how much, from whom and to whom?’ become far more vexing. The beneficiary disgorging all benefits of the wrong is part of the story, but where that is not possible or will not suffice to compensate the victim of wrongdoing we discuss various ways of allocating the cost of making the victim whole, including supplementation from public coffers.

This is an introductory article on sociobiology, particularly its relationship to eugenics. Sociobiology developed in the 1960s as a field within evolutionary biology to explain human social traits and behaviours. Although sociobiology has few direct connections to eugenics, it shares eugenics’ optimistic enthusiasm for extending biological science into the human domain, often with reckless sensationalism. Sociobiology's critics have argued that sociobiology also propagates a kind of genetic determinism and represents the zealous misapplication of science beyond its proper reach that characterized (...) the eugenics movement. More recently, evolutionary psychology represents a sophistication of sociobiology that attends to the mind as the "missing link" between evolution and behaviour (Cosmides and Tooby 1992, Pinker 1997).

In this paper I explore Michael Loux’s important distinction between “tropes” and “tropers”. First, I argue that the distinction throws into relief an ambiguity and discrepancy in the literature, revealing two fundamentally different versions of trope theory. Second, I argue that the distinction brings into focus unique challenges facing each of the resulting trope theories, thus calling into question an alleged advantage of trope theory—that by uniquely occupying the middle ground between its rivals, trope theory is able to recover and (...) preserve the insights of these views. Ultimately, the distinction suggests that trope theory is a divided house. (shrink)

With the publication of A Theory of Justice in 1971, John Rawls not only rejuvenated contemporary political philosophy but also defended a Kantian form of Enlightenment liberalism called “justice as fairness.” Enlightenment liberalism stresses the development and exercise of our capacity for autonomy, while Reformation liberalism emphasizes diversity and the toleration that encourages it. These two strands of liberalism are often mutually supporting, but they conflict in a surprising number of cases, whether over the accommodation of group difference, the design (...) of civic education, or the promotion of liberal values internationally. During the 1980’s, however, Rawls began to jettison key Kantian characteristics of his theory, a process culminating in the 1993 release of Political Liberalism and completing the transformation of justice as fairness into a Reformation liberalism. -/- Reconstructing Rawls argues that this transformation was a tragic mistake because it jeopardized the most important features of his theory, viz. the lexical priorities of right, liberty, and fair equality of opportunity as well as the difference principle. Controversially, this book contends that Rawls’s so-called “political turn,” motivated by a newfound interest in diversity and the accommodation of difference, has been unhealthy for autonomy-based liberalism and has pushed liberalism more broadly towards cultural relativism, be it in the guise of liberal multiculturalism or critiques of cosmopolitan distributive-justice theories. The book then demonstrates that the central elements of justice as fairness can only be defended within the context of a Kantian Enlightenment liberalism and that Rawls’s hope for a more pluralistic grounding for his theory, endorsed by a wide variety of belief systems present in modern democratic societies, is illusory. -/- Reconstructing Rawls is the first book to systematically compare Rawls’s and Kant’s theories and the first to offer an internal critique and reconstruction of justice as fairness, reconceiving it as a comprehensive, universalistic Kantian liberalism. By doing so, it gives us both the vision of a liberal world order—“a republicanism of all states, together and separately,” as Kant put it—and a mode of justification addressed to all men and women, not as members of particular nations, races, and faiths, but as human beings, as citizens of the world. In short, it reclaims Rawls for the Enlightenment. (shrink)

The lexical priority of fair equality of opportunity in John Rawls’s justice as fairness, which has been sharply criticized by Larry Alexander and Richard Arneson among others, is left almost entirely undefended in Rawls’s works. I argue here that this priority rule can be successfully defended against its critics despite Rawls’s own doubts about it. Using the few textual clues he provides, I speculatively reconstruct his defense of this rule, showing that it can be grounded on our interest in self-realization (...) through work. This reconstructed defense makes liberal use of concepts already present in A Theory of Justice , including the Aristotelian Principle (which motivates the achievement of increasing virtuosity) and the Humboldtian concept of social union (which provides the context for the development of such virtuosity). I also show that this commitment to self-realization, far from violating the priority of right in Rawls’s theory, stems directly from his underlying commitment to autonomy, which is the very foundation of the moral law in his doctrine of right. The reconstituted defense of this priority rule not only strengthens the case for justice as fairness but also has important and controversial implications for public policy. (shrink)

Michael Almeida has recently tried to show that if S5 correctly represents metaphysical necessity, there can be no non-trivial evidence for or against the existence of the traditional God. Evidence would thus be irrelevant to the reasonability of traditional theistic belief. Almeida's argument has implications beyond its announced target: it amounts to a new argument for sweeping scepticism. Almeida's argument for the irrelevance of evidence to the existence of God would apply to any state of affairs that entails some metaphysical (...) necessity. In S5, every state of affairs entails some metaphysical necessity, so Almeida should conclude that non-trivial evidence for or against any state of affairs is impossible. I argue that the problem is not with S5 but with inadequately motivated assumptions about evidential support. Avoiding those assumptions disables the argument for sweeping scepticism and without foreclosing the possibility of non-trivial evidence for or against the existence of the traditional God. (shrink)

I examine the meaning and merits of a premise in the Exclusion Argument, the causal closure principle that all physical effects have physical causes. I do so by addressing two questions. First, if we grant the other premises, exactly what kind of closure principle is required to make the Exclusion Argument valid? Second, what are the merits of the requisite closure principle? Concerning the first, I argue that the Exclusion Argument requires a strong, “stringently pure” version of closure. The latter (...) employs two qualifications concerning the physical sufficiency and relative proximity of the physical cause required for every physical effect. The second question is addressed in two steps. I begin by challenging the adequacy of the empirical support offered by David Papineau for closure. Then I assess the merits of “level” and “domain” versions of stringently pure closure. I argue that a domain version lacks adequate and non-question-begging support within the context of the Exclusion Argument. And I argue that the level version leads to a puzzling metaphysics of the physical domain. Thus, we have grounds for rejecting the version of closure required for the Exclusion Argument. This means we can resist the Exclusion Argument while avoiding the implausible implications that come with rejecting one of its other premises. That is, because there are grounds to reject causal closure, one can reasonably affirm the non-overdeterminative causal efficacy of conscious mental states while denying that the latter are identical with physical states.

In his influential article ‘Essence and Modality’, Fine proposes a definition of necessity in terms of the primitive essentialist notion ‘true in virtue of the nature of’. Fine’s proposal is suggestive, but it admits of different interpretations, leaving it unsettled what the precise formulation of an Essentialist definition of necessity should be. In this paper, four different versions of the definition are discussed: a singular, a plural reading, and an existential variant of Fine’s original suggestion and an alternative version proposed (...) by Correia which is not based on Fine’s primitive essentialist notion. The first main point of the paper is that the singular reading is untenable. The second that given plausible background assumptions, the remaining three definitions are extensionally equivalent. The third is that, this equivalence notwithstanding, Essentialists should adopt Correia’s version of the definition, since both the existential variant, which has de facto been adopted as the standard version of the definition in the literature, and the plural reading suffer from problems connected to Fine’s primitive essentialist notion.

Historically, republicans were of different minds about markets: some, such as Rousseau, reviled them, while others, like Adam Smith, praised them. The recent republican resurgence has revived this issue. Classical liberals such as Gerald Gaus contend that neo-republicanism is inherently hostile to markets, while neo-republicans like Richard Dagger and Philip Pettit reject this characterization—though with less enthusiasm than one might expect. I argue here that the right republican attitude toward competitive markets is celebratory rather than acquiescent and that republicanism demands (...) such markets for the same reason it requires the rule of law: because both are essential institutions for protecting individuals from arbitrary interference. I reveal how competition restrains—and in the limit, even eradicates—market power and thereby helps us realize “market freedom,” i.e., freedom as non-domination in the context of economic exchange. Finally, I show that such freedom necessitates “Anglo-Nordic” economic policies. (shrink)
