Identification of factors that predict recurrent antisocial behavior is integral to the social sciences, criminal justice procedures, and the effective treatment of high-risk individuals. Here we show that error-related brain activity elicited during performance of an in- hibitory task prospectively predicted subsequent rearrest among adult offenders within 4 y of release (N =96). The odds that an offender with relatively low anterior cingulate activity would be rearrested were approximately double that of an offender with high activity in this region, holding (...) constant other observed risk factors. These results suggest a potential neurocognitive biomarker for persistent antisocial behavior. (shrink)

Betrachtet man den Gebrauch der Worte ‘Moral’ und ‘Vernunft’ etwas genauer, so stellt man fest, dass nicht klar ist, was sie bezeichnen bzw. wie Moral und Vernunft zusammenhängen. In dem Buch ‘Rationalität in der Angewandten Ethik’, in dem sich verschiedene Autoren die Aufgabe gestellt haben, diese Umstände in das Licht der Betrachtung zu rücken, finden wir Fragen darüber, wie “Moral”, “Angewandte Ethik” und “Vernunft” (auch in der Anwendung) zu verstehen und zu vereinen sind.

The doctrine of permanent sovereignty over natural resources is a hugely consequential one in the contemporary world, appearing to grant nation-states both jurisdiction-type rights and rights of ownership over the resources to be found in their territories. But the normative justification for that doctrine is far from clear. This article elucidates the best arguments that might be made for permanent sovereignty, including claims from national improvement of or attachment to resources, as well as functionalist claims linking resource rights to key (...) state functions. But it also shows that these defences are insufficient to justify permanent sovereignty and that in many cases they actually count against it as a practice. They turn out to be compatible, furthermore, with the dispersal of resource rights away from the nation-state which global justice appears to demand. (shrink)

In this paper, I critically assess Mark Richard’s interesting and important development of the claim that linguistic meanings can be fruitfully analogized with biological species. I argue that linguistic meanings qua cluster of interpretative presuppositions need not and often do not display the population-level independence and reproductive isolation that is characteristic of the biological species concept. After developing these problems in some detail, I close with a discussion of their implications for the picture that Richard paints concerning the dangers of (...) conceptual engineering and the prospects for dynamic notions of semantic stability.

This new, inexpensive translation of Plato's Apology of Socrates is an alternative to the 19th-century Jowett translation that students find online when they're trying to save money on books. Using the 1995 Oxford Classical Text and the commentaries of John Burnet and James Helm, I aimed to produce a 21st-century English translation that is both true to Plato's Greek and understandable to college students in introductory philosophy, political theory, and humanities courses. The book also includes a new translation of the (...) death scene from Plato's Phaedo, a short introduction, a dozen explanatory notes, advice on how to cite Plato in papers, and suggestions for further reading.

This paper explores some ways in which artificial intelligence (AI) could be used to improve human moral judgments in bioethics by avoiding some of the most common sources of error in moral judgment, including ignorance, confusion, and bias. It surveys three existing proposals for building human morality into AI: Top-down, bottom-up, and hybrid approaches. Then it proposes a multi-step, hybrid method, using the example of kidney allocations for transplants as a test case. The paper concludes with brief remarks about how (...) to handle several complications, respond to some objections, and extend this novel method to other important moral issues in bioethics and beyond.

In a series of papers, Donald Davidson :3–17, 1984, The philosophical grounds of rationality, 1986, Midwest Stud Philos 16:1–12, 1991) developed a powerful argument against the claim that linguistic conventions provide any explanatory purchase on an account of linguistic meaning and communication. This argument, as I shall develop it, turns on cases of what I call lexical innovation: cases in which a speaker uses a sentence containing a novel expression-meaning pair, but nevertheless successfully communicates her intended meaning to her audience. (...) I will argue that cases of lexical innovation motivate a dynamic conception of linguistic conventions according to which background linguistic conventions may be rapidly expanded to incorporate new word meanings or shifted to revise the meanings of words already in circulation. I argue that this dynamic account of conventions both resolves the problem raised by cases of lexical innovation and that it does so in a way that is preferable to those who—like Davidson—deny important explanatory roles for linguistic conventions.

A letter to The Times of London, May 9, 1992 protesting the Cambridge University proposal to award an honorary degree to M. Jacques Derrida.

This paper explores the significance of intelligent social behavior among non-human animals for philosophical theories of communication. Using the alarm call system of vervet monkeys as a case study, I argue that interpersonal communication (or what I call “minded communication”) can and does take place in the absence of the production and recognition of communicative intentions. More generally, I argue that evolutionary theory provides good reasons for maintaining that minded communication is both temporally and explanatorily prior to the use of (...) communicative intentions. After developing these negative points about the place of communicative intentions in detail, I provide a novel alternative account according to which minded communication is characterized in terms of patterns of action and response that function to coordinate the representational mental states of agents. I show that an account which centers on patterns of representational coordination of this sort is well suited to capture the theoretical roles associated with minded communication and that it does so in a way that provides a good fit with comparative facts about the presence of minded communication among non-human animals.

Our ordinary assertions are often imprecise, insofar as the way we represent things as being only approximates how things are in the actual world. The phenomenon of assertoric imprecision raises a challenge to standard accounts of both the norm of assertion and the connection between semantics and the objects of assertion. After clarifying these problems in detail, I develop a framework for resolving them. Specifically, I argue that the phenomenon of assertoric imprecision motivates a rejection of the widely held belief (...) that a semantic theory for a language associates a single semantic value with each of the simple and complex expressions of that language, relative to the contexts in which they occur. Instead, I propose that we adopt a framework I call semantic pluralism. (shrink)

In defending his interest-relative account of knowledge in Knowledge and Practical Interests (2005), Jason Stanley relies heavily on intuitions about several bank cases. We experimentally test the empirical claims that Stanley seems to make concerning our common-sense intuitions about these bank cases. Additionally, we test the empirical claims that Jonathan Schaffer seems to make in his critique of Stanley. We argue that our data impugn what both Stanley and Schaffer claim our intuitions about such cases are. To account for these (...) results, one must develop a better conception of the connection between a subject's interests and her body of knowledge than those offered by Stanley and Schaffer.

We make the case that scientifically accurate and politically feasible responses to the climate crisis require a complex understanding of human cultural practices of niche construction that moves beyond the adaptive significance of culture. We develop this thesis in two related ways. First, we argue that cumulative cultural practices of niche construction can generate stable equilibria and runaway selection processes that result in long-term existential risks within and across cultural groups. We dub this the back of the invisible hand. Second, (...) we argue that the ability of cultural groups to innovate technological solutions to environmental problems is highly constrained in ways that are exacerbated by sustained intergroup conflict, inequality and by inherently unpredictable cascades in climate change and human migration patterns. After developing these theoretical points about human cultural practices of niche construction in detail, we conclude our discussion with some tentative practical suggestions about the way that cultural evolutionary history can more fruitfully be used in efforts to remit the climate crisis and contribute to sustainable practices of human climate change adaptation.

In this paper, I explore two contrasting conceptions of the social character of language. The first takes language to be grounded in social convention. The second, famously developed by Donald Davidson, takes language to be grounded in a social relation called triangulation. I aim both to clarify and to evaluate these two conceptions of language. First, I propose that Davidson’s triangulation-based story can be understood as the result of relaxing core features of conventionalism pertaining to both common-interest and diachronic stability—specifically, (...) Davidson does not require uses of language to be self-perpetuating, in the way required by conventionalism, in order to be bona fide components of linguistic systems. Second, I argue that Davidson’s objections to conventionalism from language innovation and language variation fail, and that certain kinds of negative data in language use require an appeal to diachronic social relations. However, I also argue that recent work on communication in the a.. (shrink)

Plato is associated with the idea that the body holds us back from knowing ultimate reality and so we should try to distance ourselves from its influence. This sentiment appears is several of his dialogues including Theaetetus where the flight from the physical world is compared to becoming like God. In some major dialogues of Plato's later career such as Philebus and Laws, however, the idea of becoming like God takes a different turn. God is an intelligent force that tries (...) to create order in the physical world. I argue that likeness to God in these dialogues involves imitating God's effort by trying to order our bodies, souls, and societies as intelligence directs. Becoming like Plato's God is not to abandon the world. It is to improve it. (shrink)

If dangerous climate change is to be avoided, it is vital that carbon sinks such as tropical rainforests are protected. But protecting them has costs. These include opportunity costs: the potential economic benefits which those who currently control rainforests have to give up when they are protected. But who should bear those costs? Should countries which happen to have rainforests within their territories sacrifice their own economic development, because of our broader global interests in protecting key carbon sinks? This essay (...) develops an argument from the “principle of fairness,” which seeks to establish that outsiders should pay states with rainforests so as to share the costs of protection. If they do not, they can be condemned for free-riding on forest states. The argument is, I suggest, compelling and also capable of enjoying support from adherents of a wide variety of positions on global justice. (shrink)

Dozens of countries have established Sovereign Wealth Funds (SWFs) in the last decade or so, in the majority of cases employing those funds to manage the large revenues gained from selling resources such as oil and gas on a tide of rapidly rising commodity prices. These funds have raised a series of ethical questions, including just how the money contained in such funds should eventually be spent. This article engages with that question, and specifically seeks to connect debates on SWFs (...) with debates onglobaljustice. Just how good are national claims to the great wealth contained in SWFs in the first place? Using the example of Norway's very large SWF – derived from selling North-Sea petroleum – I show that national claims are at least sometimes very weak, with the implication that the wealth in many such funds is ripe for redistribution in the interests of global justice. I conclude by offering some guidance for how the money contained in such funds could best be spent, with the goal of advancing global justice. (shrink)

This dissertation identifies and explains four major contributions of the Laws and related late dialogues to Plato's moral and political philosophy. -/- Chapter 1: I argue that Plato thinks the purpose of laws and other social institutions is the happiness of the city. A happy city is one in which the city's parts, i.e. the citizens, are unified under the rule of intelligence. Unlike the citizens of the Republic, the citizens of the Laws can all share the same true judgments (...) of value, and this unanimity explains the city's unity. Plato thinks that aiming at the city's happiness is justified, moreover, because a unified city contributes to the universe's order. -/- Chapter 2: In the Laws, Plato holds that the sick, poor, ugly, weak, but virtuous are happy, and that health, wealth, beauty, and strength benefit the virtuous but harm the vicious. Only in the Laws does Plato commit himself to all these claims simultaneously, and I explain how the moral psychology of the Laws permits Plato to maintain them coherently. -/- Chapter 3: I argue that, in the Laws, becoming virtuous is the same as becoming like God. Becoming like God does not require escape from the world of change as it does in the Theaetetus, however. Rather, becoming like God requires bringing "measure" or appropriate order to the world of change, especially to those entities over which we have the most control—our own souls. In the Laws, citizens achieve this order as they learn to be just and to understand the nature of reality. -/- Chapter 4: Unlike the Republic and Statesman, the Laws holds that obedience of the citizens to their laws should be effected, if possible, with rational persuasion. I argue that Plato wishes such persuasion to educate the citizens of the reasons for the laws. Understanding the laws' justification is the principal way in which citizens acquire the good judgment necessary for virtue. The city becomes more happy as the citizens progress in virtue, so rational persuasion is a necessary means to the lawgiver's overall aim. (shrink)

This paper will argue that there is no such thing as introspective access to judgments and decisions. I t won't challenge the existence of introspective access to perceptual and imagistic states, nor to emotional feelings and bodily sensations. On the contrary, the model presented in Section 2 presumes such access. Hence introspection is here divided into two categories: introspection of propositional attitude events, on the one hand, and introspection of broadly perceptual events, on the other. I shall assume that the (...) latter exists while arguing that the fonner doesn't . Section I makes some preliminary points and distinctions, and outlines the scope of the argument. Section 2 presents and motivates the general model of introspection that predicts a divided result. Section 3 provides independent evidence for the conclusion that judgments and decisions aren't introspectable. Section 4 then replies to a number of objections to the argument, the most important of which is made from the perspective of so-called "dual systems theories" of belief formation and decision making, The upshot is a limited form of eliminativism about introspection, in respect of at least two core categories of propositional attitude.

The central claim of my paper is that pragmatics has a wider scope of application than has been generally appreciated. In particular, I will argue that many discussions of pragmatics are guilty of a problematic form of provincialism. The provincialism at issue restricts the class of target systems of study to those involving groups of developmentally typical humans (or slightly idealized versions thereof), either explicitly as a matter of principle or implicitly as consequence of how it construes the underlying pragmatic (...) notions. In what follows, I will argue that this kind of provincialism is problematic because there are patterns of non-human animal social interaction that cannot be properly explained without recourse to the theoretical tool-kit of pragmatics. Crucially, rejecting provincialism about pragmatics does not entail that there are not important theoretical differences between human and non-human systems of pragmatics. It does, however, require that our core philosophical theories of social interaction and communication be centered on features independent not merely of those at work in human languages but also of uniquely human features of cognition and sociality more generally.

Purpose This paper aims to formalize long-term trajectories of human civilization as a scientific and ethical field of study. The long-term trajectory of human civilization can be defined as the path that human civilization takes during the entire future time period in which human civilization could continue to exist. -/- Design/methodology/approach This paper focuses on four types of trajectories: status quo trajectories, in which human civilization persists in a state broadly similar to its current state into the distant future; catastrophe (...) trajectories, in which one or more events cause significant harm to human civilization; technological transformation trajectories, in which radical technological breakthroughs put human civilization on a fundamentally different course; and astronomical trajectories, in which human civilization expands beyond its home planet and into the accessible portions of the cosmos. -/- Findings Status quo trajectories appear unlikely to persist into the distant future, especially in light of long-term astronomical processes. Several catastrophe, technological transformation and astronomical trajectories appear possible. -/- Originality/value Some current actions may be able to affect the long-term trajectory. Whether these actions should be pursued depends on a mix of empirical and ethical factors. For some ethical frameworks, these actions may be especially important to pursue. (shrink)

In this paper, we focus on whether and to what extent we judge that people are responsible for the consequences of their forgetfulness. We ran a series of behavioral studies to measure judgments of responsibility for the consequences of forgetfulness. Our results show that we are disposed to hold others responsible for some of their forgetfulness. The level of stress that the forgetful agent is under modulates judgments of responsibility, though the level of care that the agent exhibits toward performing (...) the forgotten action does not. We argue that this result has important implications for a long-running debate about the nature of responsible agency. (shrink)

Case reports about patients undergoing Deep Brain Stimulation (DBS) for various motor and psychiatric disorders - including Parkinson’s Disease, Obsessive Compulsive Disorder, and Treatment Resistant Depression - have sparked a vast literature in neuroethics. Questions about whether and how DBS changes the self have been at the fore. The present chapter brings these neuroethical debates into conversation with recent research in moral psychology. We begin in Section 1 by reviewing the recent clinical literature on DBS. In Section 2, we consider (...) whether DBS poses a threat to personal identity. In Section 3 we argue for engagement with recent empirical work examining judgements of when identity changes. We conclude in Section 4 by highlighting a range of ethical issues raised by DBS, including various cross-cultural considerations. (shrink)

A review of *The Social Origins of Language* by Robert M. Seyfarth and Dorothy L. Cheney; edited and introduced by Michael L. Platt.

People maintain a positive identity in at least two ways: They evaluate themselves more favorably than other people, and they judge themselves to be better now than they were in the past. Both strategies rely on autobiographical memories. The authors investigate the role of autobiographical memories of lying and emotional harm in maintaining a positive identity. For memories of lying to or emotionally harming others, participants judge their own actions as less morally wrong and less negative than those in which (...) other people lied to or emotionally harmed them. Furthermore, people judge those actions that happened further in the past to be more morally wrong than those that happened more recently. Finally, for periods of the past when they believed that they were very different people than they are now, participants judge their actions to be more morally wrong and more negative than those actions from periods of their pasts when they believed that they were very similar to who they are now. The authors discuss these findings in relation to theories about the function of autobiographical memory and moral cognition in constructing and perceiving the self over time. (shrink)

Much of the literature from political psychology has focused on the negative traits that are positively associated with affective polarization—e.g., animus, arrogance, distrust, hostility, and outrage. Not as much attention has been focused on the positive traits that might be negatively associated with polarization. For instance, given that people who are intellectually humble display greater openness and less hostility towards conflicting viewpoints (Krumrei-Mancuso & Rouse, 2016; Hopkin et al., 2014; Porter & Schumann, 2018), one might reasonably expect them to be (...) less polarized. -/- We ran two studies designed to explore the relationship between various forms of humility and polarization. Our chief finding is that people who value humility are prone to what we are calling epistemic polarization—that is, judging the epistemic traits of contrapartisans negatively—which in turn plays a role in polarization more generally. Not only are contrapartisans deemed to have the wrong moral and political beliefs, they are also viewed as less humble and more arrogant, close-minded, and irrational. This makes matters even worse when it comes to the growing partisan divide. In light of our findings, we believe that the novel concept of epistemic polarization that we introduce is a promising target for further investigation. (shrink)

In the ontology of music the Aristotelian theory of musical works is the view that musical works are immanent universals. The Aristotelian theory (hereafter Musical Aristotelianism) is an attractive and serviceable hypothesis. However, it is overlooked as a genuine competitor to the more well-known theories of Musical Platonism and nominalism. Worse still, there is no detailed account in the literature of the nature of the universals that the Aristotelian identifies musical works with. In this paper, I argue that the best (...) version of Musical Aristotelianism identifies musical works with structural universals. I first motivate the view by outlining its explanatory benefits. I then argue that Musical Aristotelianism is preferable to Musical Platonism and present a novel account of musical works as structural universals by developing D. M. Armstrong’s theory of structural universals. I discuss the consequences of Musical Aristotelianism with respect to on-going issues in debates about musical works and defend the view against an influential objection, concluding that Musical Aristotelianism is a genuine competitor in debates about the nature of musical works.

This chapter by Fisher continues the theme of the relation between Armstrong and Lewis, only Fisher casts the net far wider. He begins by arguing that there were at least two different lines of influence from early twentieth-century behaviourism to the identity theory: one through logical positivism and the other through ordinary language philosophy, the latter involving Place and Smart, and Lewis and Armstrong. It was Armstrong and Lewis who were to have a profound influence on subsequent (...) developments in analytic philosophy, both methodologically and in metaphysics, and it is for this reason that Fisher devotes the rest of his chapter to tracing the origins of their theories of mind and the manner in which the emphases and methodologies deployed in developing their respective theories became the hallmarks of their wider impact on analytic philosophy.

Resemblances obtain not only between objects but between properties. Resemblances of the latter sort - in particular resemblances between quantitative properties - prove to be the downfall of a well-known theory of universals, namely the one presented by David Armstrong. This paper examines Armstrong's efforts to account for such resemblances within the framework of his theory and also explores several extensions of that theory. All of them fail.

David Lewis is typically interpreted as a class nominalist. One consequence of class nominalism, which he embraced, is that the reduction of ordered pairs, triples, etc to unordered sets of sets is conventional. The reaction by his Australian counterparts D.M. Armstrong and Peter Forrest was that Lewis was not being ontologically serious. This chapter evaluates this debate over serious ontology. It is argued that in one sense Lewis is ontologically serious, but that his additional commitment to structuralism about classes (...) should push him to adopt a trope-theoretic account of naturalness, which opens up another way to respond to the charge of not doing serious ontology. This conclusion is supported by certain remarks he makes in his correspondence, thus revealing how his thinking about properties appears to have evolved from property-egalitarianism to a sparse theory of tropes.

In this paper I outline the main features of Karen Bennett’s (Australasian Journal of Philosophy 1–21, 2011) non-classical mereology, and identify its methodological costs. I argue that Bennett’s mereology cannot account for the composition of structural universals because it cannot explain the mereological difference between isomeric universals, such as being butane and being isobutane. I consider responses, which come at costs to the view.

Abstract: In chapter 15 of A Materialist Theory of the Mind, D.M.Armstrong offers an account of what he calls “the biological value of introspection”, namely, that “without information…about the current state of our minds, purposive trains mental activity would be impossible.” This paper examines and assesses Armstrong’s “Just-so story about introspective consciousness”—as W.G.Lycan later called it. One moral will be that appreciating this aspect of Armstrong’s view blurs the difference between his own perceptual model of introspection, and (...) the anti-perceptual models advanced by such critics as Sydney Shoemaker .

D. M. Armstrong rejects various ontologies that posit truths without truthmakers. But, lest proponents of such questionable ontologies postulate suspicious truthmakers in a bid to regain ontological respectability, Armstrong requires a plausible restriction on truthmaking that eliminates such ontologies. I discuss three different candidate restrictions: categorical, natural, and intrinsic difference-making. While the categorical and natural restrictions eliminate the questionable ontologies, they also eliminate Armstrong’s own ontology. The intrinsic difference-making restriction, on the other hand, fails to eliminate any (...) of them. Thus Armstrong lacks a principled reason for rejecting such ontologies. (shrink)

The title of this paper reflects the fact that truthmaking is quite frequently considered to be expressive of realism. What this means, exactly, will become clearer in the course of our discussion, but since we are interested in Armstrong’s work on truthmaking in particular, it is natural to start from a brief discussion of how truthmaking and realism appear to be associated in his work. In this paper, special attention is given to the supposed link between truthmaking and realism, (...) but it is argued that this link should not be taken too seriously, as truthmaking turns out to be, to a large extent, ontologically neutral. Some consequences of this are studied. (shrink)

This paper has two components. The first, longer component (sec. 1-6) is a critical exposition of Armstrong’s views about the metaphysics of mathematics, as they are presented in Truth and Truthmakers and Sketch for a Systematic Metaphysics. In particular, I discuss Armstrong’s views about the nature of the cardinal numbers, and his account of how modal truths are made true. In the second component of the paper (sec. 7), which is shorter and more tentative, I sketch an alternative (...) account of the metaphysics of mathematics. I suggest we insist that mathematical truths have physical truthmakers, without insisting that mathematical objects themselves are part of the physical world. (shrink)

David Armstrong (1926-2014) was much the most internationally successful philosopher to come from Sydney. His life moved from a privileged Empire childhood and student of John Anderson to acclaimed elder statesman of realist philosophy. His philosophy developed from an Andersonian realist inheritance to major contributions on materialist theory of mind and the theory of universals. His views on several other topics such as religion and ethics are surveyed briefly.

Provocatively, David Armstrong's properties are supposed to be both universals and spatio-temporal. What does this amount to? I consider four of Armstrong's views, in order of ascending plausibility: (1) the exemplification account, on which universals are exemplified by space-times; (2) the location account, on which universals are located at space-times; (3) the first constituent account, on which spatio-temporal relations are elements of what I call the form of time; and, the true view, (4) the second constituent account, on (...) which universals are spatio-temporal only 'derivatively' by being constituents of states of affairs which are so 'primarily'. The first two accounts are rejected because they entail that space-times must be substantival. In making plausible the second constituent account, I distinguish primitive and derivative spatio-temporality. Something is primitively spatio-temporal when it is at a space-time, or stands in spatio-temporal relations. Something is derivatively spatio-temporal when it is a constituent of something primitively spatio-temporal. (shrink)

Cyclist Lance Armstrong cheated his way to seven Tour de France . Such cheating is wrong because it harms society. To explain how that harm affects all of us, I use Aristotle's ideas of virtue ethics to argue that Armstrong, despite his charitable work, is not a virtuous person. Virtue is to some extent determined by society, so we need to be clear that Armstrong is not a person to emulate. A society which does not clearly disapprove (...) of vice is less than it might otherwise be because a good society is one that encourages virtue in its citizens. (shrink)

In this article, I will focus on the notion of supervenience introduced and deployed by Armstrong. The aim is to settle the issue of whether it has any fruitful applications. My conclusions are negative. Armstrong gives to his notion of supervenience a major explanatory role of telling why one need not consider certain beings as a genuine ontic expansion, if one already assumes a certain meagre set of more basic entities. On closer inspection, however, Armstrong’s notion does (...) not clarify such intuitions any further. The legitimate uses of the notion for the above purpose turn out to be redundant: the concepts of identity and partial identity can be employed instead. (shrink)

The Forrest-Armstrong argument, as reconfigured by David Lewis, is a reductio against an unrestricted principle of recombination. There is a gap in the argument which Lewis thought could be bridged by an appeal to recombination. After presenting the argument, I show that no plausible principle of recombination can bridge the gap. But other plausible principles of plenitude can bridge the gap, both principles of plenitude for world contents and principles of plenitude for world structures. I conclude that the Forrest- (...) class='Hi'>Armstrong argument, when fortified in one of these ways, demands that unrestricted recombination be rejected. The appropriate restriction comes from a consideration of what world structures are possible. I argue that, although there are too many worlds to form a set, for any world, the individuals at that world do form a set. To defend it I invoke a principle of Limitation of Size together with an iterative conception of structure. (shrink)

Philosophical lessons come in many different shapes and sizes. Some lessons are big, some are small. Some lessons go deep and have a big impact, some are shallow and have almost none. Some lessons are not really philosophical at all or would not really be lessons for an audience of academic philosophers. I mention these truisms not to disparage this informative book on 'moral OCD' (moral obsessive-compulsive disorder, or 'Scrupulosity') but rather to emphasize how difficult it can be to discern (...) the book's intended audience, given its interdisciplinary aims and structure. That question is never explicitly addressed (it is admittedly a slim book, slimmer than it appears), but the question has consequences for how to think about the book's ultimate value, and for whom. The book might attract two groups in particular: philosophers working on the nature of responsibility (the subject of the book's longest chapter) and psychiatric researchers or mental health professionals interested in moral philosophy and the philosophy of mental illness. I will return to what moral philosophers can learn from moral OCD, but there will be spoilers. (shrink)

A polemical account of Australian philosophy up to 2003, emphasising its unique aspects (such as commitment to realism) and the connections between philosophers' views and their lives. Topics include early idealism, the dominance of John Anderson in Sydney, the Orr case, Catholic scholasticism, Melbourne Wittgensteinianism, philosophy of science, the Sydney disturbances of the 1970s, Francofeminism, environmental philosophy, the philosophy of law and Mabo, ethics and Peter Singer. Realist theories especially praised are David Armstrong's on universals, David Stove's on logical (...) probability and the ethical realism of Rai Gaita and Catholic philosophers. In addition to strict philosophy, the book treats non-religious moral traditions to train virtue, such as Freemasonry, civics education and the Greek and Roman classics. (shrink)

I will present and criticise the two theories of truthmaking David Armstrong offers us in Truth and Truthmakers (Armstrong 2004), show to what extent they are incompatible and identify troublemakers for both of them, a notorious – Factualism, the view that the world is a world of states of affairs – and a more recent one – the view that every predication is necessary. Factualism, combined with truthmaker necessitarianism – ‘truthmaking is necessitation’ – leads Armstrong to an (...) all-embracing totality state of affairs that necessitates not only everything that is the case but also everything else – that which is not the case, that which is merely possible or even impossible. All the things so dear to realists – rocks, natural properties, real persons – become mere abstractions from this ontological monster. The view that every predication is necessary does in some sense the opposite: it does away with totality states of affairs and, arguably, also with states of affairs. We have particulars and universals, partially identical and necessarily connected to everything else. Just by the existence of anything, everything is necessitated – the whole world mirrored in every monad. Faced with the choice between these two equally unappealing alternatives, I suggest returning to Armstrong’s more empiricist past: the world is not an all-inclusive One, nor necessitated by every single particular and every single universal, but a plurality of particulars and universals, interconnected by a contingent and internal relation of exemplification. While a close variant, truthmaker essentialism, can perhaps be saved, this means giving up on truthmaker necessitarianism. This, I think, what it takes to steer a clear empiricist course between the Scylla of Spinozist general factness and the Charybdis of a Leibnizian overdose of brute necessities. (shrink)

This paper is concerned with what I call the ‘problem of unity’ . This is the puzzle of how Armstrong‐like states of affairs are unified. The general approach is ‘relational internalism’: the unifier of such a state of affairs is a relation of some sort in it. A view commonly associated with relational internalism is that if such a relation satisfies a certain ‘naive’ expectation to a relation – that it is related to its relata – then Bradley's regress (...) results. As I argue, for one very natural species of relational internalism, this is indeed the case. Influential writers on the topic have therefore maintained that this relation is not related to its relata. But, as we shall see, while this ‘classic’ relational internalism obviously avoids Bradley's regress, intuitively, it fails completely to solve the problem of unity. I argue, however, that given the rejection of a natural, but unfounded, assumption of conventional relational internalism, a unique relation can unify states of affairs without leading to Bradley's regress. I consequently propose a novel version of relational internalism on which states of affairs are unified by such an entity. (shrink)

Gardeners, poets, lovers, and philosophers are all interested in the redness of roses; but only philosophers wonder how it is that two different roses can share the same property. Are red things red because they resemble each other? Or do they resemble each other because they are red? Since the 1970s philosophers have tended to favour the latter view, and held that a satisfactory account of properties must involve the postulation of either universals or tropes. But Gonzalo Rodriguez-Pereyra revives the (...) dormant alternative theory of resemblance nominalism, showing first that it can withstand the attacks of such eminent opponents as Goodman and Armstrong, and then that there are reasons to prefer it to its rival theories. The clarity and rigour of his arguments will challenge metaphysicians to rethink their views on properties. (shrink)

O discurso a respeito dos Mundos Possíveis pode ser uma ferramenta bastante útil para a filosofia. Pode ser útil, por exemplo, para a compreensão das modalidades, da necessidade e da possibilidade. No entanto, para utilizar o discurso dos Mundos Possíveis devemos ter uma explicação satisfatória do caráter ontológico da Semântica dos Mundos Possíveis. Para isso, precisamos responder a questões do tipo: O que é um Mundo Possível? De que forma eles existem? Em quantos Mundos Possíveis podemos falar? Há diversas formas (...) de responder a estas perguntas. Neste trabalho pretendemos apresentar duas teorias que possuem uma abordagem realista para a noção de Mundo Possível. Cada uma dessas teorias atribuiu um caráter ontológico diferente para a noção de Mundo Possível e, portanto, uma metafísica diferente. A primeira delas é o Realismo Modal Extremo, teoria atribuída a David Lewis que defende a existência genuína de uma pluralidade de Mundos Possíveis. A segunda teoria é a teoria combinatória da possibilidade de David Armstrong. Essa teoria é uma versão das teorias do atualismo modal que também são teorias realista em relação à existência de mundos possíveis, mas que dão prioridade ao mundo atual. Por fim, pretendemos comparar as duas teorias e avaliar qual é mais vantajosa levando em consideração o custo ontológico de cada uma delas, (i.e., em relação ao número de entidades postuladas) para termos uma metafísica mais econômica.

Vallicella’s influential work makes a case that, when formulated broadly, as a problem about unity, Bradley’s challenge to Armstrongian states of affairs is practically insurmountable. He argues that traditional relational and non-relational responses to Bradley are inadequate, and many in the current metaphysical debate on this issue have come to agree. In this paper, I argue that such a conclusion is too hasty. Firstly, the problem of unity as applied to Armstrongian states of affairs is not clearly defined; in fact, (...) it has taken a number of different forms each of which need to be carefully distinguished and further supported. Secondly, once we formulate the problem in more neutral terms, as a request for a characterization of the way that particulars, universals, and states of affairs stand to one another, it can be adequately addressed by an Armstrongian about states of affairs. I propose the desiderata for an adequate characterization and present a neo-Armstrongian defense of states of affairs that meets those desiderata. The latter relies on an important distinction between different notions of fundamentality and existential dependence. (shrink)

Defenders of the Kantian maxim, i.e. ‘ought’ implies ‘can’, defend the maxim taking the term “implication” in the sense of ‘entailment’. But if it is granted that “implication” means entailment, then it can be shown that the Kantian maxim that ‘ought’ implies ‘can’ is false. Sinnott-Armstrong attempts to prove the falsity of the maxim by his argument from Self-Imposed Impossibility in which he offers his famous example of Adams. But Sinnott-Armstrong’s example of Adams appears to be not strong (...) enough to prove the falsity of the maxim; it is a subject to be captured by a version of the maxim, namely the Maxim-KT. That is why two new examples of the argument from Self-Imposed Impossibility are presented in this paper which are stronger and are able to prove the falsity of the Kantian maxim. (shrink)
