Inspired by recent progress in multi-agent Reinforcement Learning (RL), in this work we examine the collective intelligent behaviour of theoretical universal agents by introducing a weighted mixture operation. Given a weighted set of agents, their weighted mixture is a new agent whose expected total reward in any environment is the corresponding weighted average of the original agents' expected total rewards in that environment. Thus, if RL agent intelligence is quantified in terms of performance across environments, the weighted mixture's intelligence is (...) the weighted average of the original agents' intelligences. This operation enables various interesting new theorems that shed light on the geometry of RL agent intelligence, namely: results about symmetries, convex agent-sets, and local extrema. We also show that any RL agent intelligence measure based on average performance across environments, subject to certain weak technical conditions, is identical (up to a constant factor) to performance within a single environment dependent on said intelligence measure.

While researchers in business ethics, moral philosophy, and jurisprudence have advanced the study of corporate agency, there have been very few attempts to bring together insights from these and other disciplines in the pages of the Journal of Business Ethics. By introducing to an audience of business ethics scholars the work of outstanding authors working outside the field, this interdisciplinary special issue addresses this lacuna. Its aim is to encourage the formulation of innovative arguments that reinvigorate the study of corporate (...) agency and stimulate further cross-fertilization of ideas between business ethics, law, philosophy, and other disciplines.

Democracy is one of the virtues we ache for, as many now observe an undemocratic society as a savage society. Richard L. Sklar built up a hypothesis called developmental democracy in which he opines that democracy will essentially prompts the improvement of African people and states. For the most part, there has been contention whether development precedes democracy or rather democracy helps development, which is very much unclear. Regardless of the answer, since the prodemocracy charges hit Africa since 1990s, democracy (...) has not made substantial strides. There have still been huge issues of underdevelopment, corruption and mal-administration. Many have started scrutinizing the possibility of democracy been ideal for Africa. The purpose of this paper is to audit the possibility of developmental democracy within African context. This paper presents that democracy is not ideal for Africa, it likewise guarantees that, if democracy is really what it is said to be, there would not have been any requirement for polarization, for instance, developmental, liberal, social democracies and so on. This is because any democracy will essentially include all. It is on this background that the paper attempts to criticize Richard’s Sklar’s idea of developmental democracy. (shrink)

This essay is a critical notice of David Dyzenhaus's book, The Long Arc of Legality. I argue that Dyzenhaus’s criterion for distinguishing legal pathologies that undermine law's contractarian claim to legitimacy and political pathologies that do not is unsustainable. It relies on a categorical distinction between the threat to law's legitimacy posed by treating some subjects as de jure second-class citizens, whose formal legal status is compromised, and other threats to political legitimacy grounded in the treatment of some subjects (...) as de facto second-class citizens, who retain full formal legal equality but suffer from thoroughgoing substantive subordination. But some forms of de facto second-class citizenship are a greater threat to contractarian legitimacy than some forms of full formal equality. So formal equality for subjects and legal legitimacy come apart. I consider and respond to several responses on Dyzenhaus's behalf, and conclude by proposing a version of his jurisprudential theory that relaxes this distinction. (shrink)

The received view of Kripke's Wittgenstein on Rules and Private Language is that it fails as an interpretation because, inter alia, it ignores or overlooks what Wittgenstein has to say in the second paragraph of Philosophical Investigations 201. In this paper, I demonstrate that the paragraph in question is in fact fully accommodated within Kripke's reading, and cannot therefore be reasonably utilised to object to it. -/- In part one I characterise the objection; in part two I explain why it (...) fails; in part three I suggest why commentators might have been motivated to offer it; and in part four I claim that two commentators who have offered it also imply otherwise.

This paper rereads David Hume's Dialogues Concerning Natural Religion as dramatising a distinctive, naturalistic account of toleration. I have two purposes in mind: first, to complete and ground Hume's fragmentary explicit discussion of toleration; second, to unearth a potentially attractive alternative to more recent, Rawlsian approaches to toleration. To make my case, I connect Dialogues and the problem of toleration to the wider themes of naturalism, scepticism and their relation in Hume's thought, before developing a new interpretation of Dialogues (...) part 12 as political drama. Finally, I develop the Humean theory of toleration I have discovered by comparison between Rawls's and Hume's strategies for justification of a tolerant political regime. (shrink)

According to the Rationality Constraint, our concept of belief imposes limits on how much irrationality is compatible with having beliefs at all. We argue that empirical evidence of human irrationality from the psychology of reasoning and the psychopathology of delusion undermines only the most demanding versions of the Rationality Constraint, which require perfect rationality as a condition for having beliefs. The empirical evidence poses no threat to more relaxed versions of the Rationality Constraint, which only require only minimal rationality. Nevertheless, (...) we raise problems for all versions of the Rationality Constraint by appealing to more extreme forms of irrationality that are continuous with actual cases of human irrationality. In particular, we argue that there are conceivable cases of “mad belief” in which populations of Lewisian madmen have beliefs that are not even minimally rational. This undermines Lewis’s claim that our ordinary concept of belief is a theoretical concept that is implicitly defined by its role in folk psychology. We argue that introspection gives us a phenomenal concept of belief that cannot be analyzed by applying Lewis’s semantics for theoretical terms. (shrink)

La logica modale è nata per studiare i ragionamenti su ciò che è possibile e ciò che è necessario. Negli ultimi decenni, a partire dal lavoro di logici e filosofi quali Rudolf Carnap, Saul Kripke e David Lewis, la sua applicazione è stata progressivamente estesa ad altri ambiti, quali il ragionamento sul tempo, sulla conoscenza e sui sistemi di norme. Queste ricerche hanno condotto a un complesso e intrigante dialogo con alcune fondamentali branche della filosofia: la metafisica, l’epistemologia, la (...) filosofia del linguaggio. Lo scopo del volume è offrire una panoramica di questo dialogo al contempo accessibile e rigorosa, pensata sia per gli studenti di un corso universitario, sia per il lettore non specialista. Se da un lato tutte le necessarie nozioni tecniche sono rese accessibili ai non addetti ai lavori, dall'altro si restituisce un'immagine fedele delle sfide concettuali che la ricerca in questi settori è oggi chiamata ad affrontare.

Saunders Mac Lane famously remarked that "Bourbaki just missed" formulating adjoints in a 1948 appendix (written no doubt by Pierre Samuel) to an early draft of Algebre--which then had to wait until Daniel Kan's 1958 paper on adjoint functors. But Mac Lane was using the orthodox treatment of adjoints that only contemplates the object-to-object morphisms within a category, i.e., homomorphisms. When Samuel's treatment is reconsidered in view of the treatment of adjoints using heteromorphisms or hets (object-to-object morphisms between objects in (...) different categories), then he, in effect, isolated the concept of a left representation solving a universal mapping problem. When dualized to obtain the concept of a right representation, the two halves only need to be united to obtain an adjunction. Thus Samuel was only a now-simple dualization away for formulating adjoints in 1948. Apparently, Bodo Pareigis' 1970 text was the first and perhaps only text to give the heterodox "new characterization" (i.e., heteromorphic treatment) of adjoints. Orthodox category theory uses various relatively artificial devices to avoid formally recognizing hets--even though hets are routinely used by the working mathematician. Finally we consider a "philosophical" question as to whether the most important concept in category theory is the notion of an adjunction or the notion of a representation giving a universal mapping property (where adjunctions arise as the special case of a bi-representation of dual universal mapping problems).

Just when philosophers of science thought they had buried Freud for the last time, he has quietly reappeared in the writings of moral philosophers. Two analytic ethicists, Samuel Scheffler and John Deigh, have independently applied Freud’s theory of the superego to the problem of moral motivation. Scheffler and Deigh concur in thinking that although Freudian theory doesn’t entirely solve the problem, it can nevertheless contribute to a solution.

The philosophy of Samuel Clarke is of central importance for an adequate understanding of Hume’s Treatise.2 Despite this, most Hume scholars have either entirely overlooked Clarke’s work, or referred to it in a casual manner that fails to do justice to the significance of the Clarke-Hume relationship. This tendency is particularly apparent in accounts of Hume’s views on space in Treatise I.ii. In this paper, I argue that one of Hume’s principal objectives in his discussion of space is to discredit (...) Clarke’s Newtonian doctrine of absolute space and, more deeply, the ‘argument a priori’ that Clarke constructs around it. On the basis of this interpretation, I argue that Hume’s ‘system’ of space constitutes an important part of his more fundamental ‘atheistic’ or anti- Christian objectives in the Treatise.3. (shrink)

The philosophy of Samuel Clarke is of central importance to Hume’s Treatise. Hume’s overall attitude to Clarke’s philosophy may be characterized as one of systematic scepticism. The general significance of this is that it sheds considerable light on Hume’s fundamental “atheistic” or anti-Christian intentions in the Treatise. These are all claims that I have argued for elsewhere.’ In this paper I am concerned to focus on a narrower aspect of this relationship between the philosophies of Clarke and Hume. Specifically, I (...) will consider Hume’s views on the subjects of materialism and necessity in relation to Clarke’s enormously influential debate with Anthony Collins on these topics. I begin by describing the nature and context of this controversy; I then examine how Hume‘s positions on questions of materialism and necessity stand in relation to the positions and arguments taken up by Clarke and Collins; and finally I explain the deeper significance of these specific issues for Hume’s wider “atheistic” or anti-Christian objectives in the Treatise. Hume’s views on the closely related subjects of materialism and necessity, I maintain, constitute core elements of his “atheistic” project in the Treatise, and they manifest his basic antipathy to the theistic metaphysics of the Christian religion in general,and to the Newtonian cosmology of Clarke in particular.

My principal objective in this essay will be to show that the widely held view that Hume's Treatise' is not significantly or "directly" concerned with problems of religion is seriously mistaken. I shall approach this issue by way of an examination of a major skeptical theme that runs throughout the Treatise; namely, Hume's skepticism regarding the powers of demonstrative reason. In this paper I shall be especially concerned to bring to light the full significance of this skeptical theme by placing (...) Hume's arguments in their appropriate historical context. I shall show that both Hume and his contemporaries recognized that these important skeptical arguments were aimed primarily against the dogmatic Christian rationalism of John Locke and above all Samuel Clarke, and that they were, therefore, well aware that these arguments had considerable theological significance.

This essay is my brief review of Nicholas Phillipson’s biography of Adam Smith. I discuss the highlights of his treatment of Smith’s fascinating life. Phillipson does a beautiful job of surveying Smith’s academic career. Especially useful is Phillipson’s discussion of the influence David Hume had on Smith’s thought, as well as the influences of Montesquieu, Samuel Johnson, Voltaire, Rousseau, and others.

[This is an edited version of a keynote talk at the conference on Neural Information Processing Systems (NeurIPS) on November 28, 2022, with some minor additions and subtractions.] -/- There has recently been widespread discussion of whether large language models might be sentient or conscious. Should we take this idea seriously? I will break down the strongest reasons for and against. Given mainstream assumptions in the science of consciousness, there are significant obstacles to consciousness in current models: for example, their (...) lack of recurrent processing, a global workspace, and unified agency. At the same time, it is quite possible that these obstacles will be overcome in the next decade or so. I conclude that while it is somewhat unlikely that current large language models are conscious, we should take seriously the possibility that successors to large language models may be conscious in the not-too-distant future.

The singularity hypothesis is a radical hypothesis about the future of artificial intelligence on which self-improving artificial agents will quickly become orders of magnitude more intelligent than the average human. Despite the ambitiousness of its claims, the singularity hypothesis has been defended at length by leading philosophers and artificial intelligence researchers. In this paper, I argue that the singularity hypothesis rests on scientifically implausible growth assumptions. I show how leading philosophical defenses of the singularity hypothesis (Chalmers 2010, Bostrom 2014) fail (...) to overcome the case for skepticism. I conclude by drawing out philosophical implications of this discussion for our understanding of consciousness, personal identity, digital minds, existential risk, and ethical longtermism.

Thomas Kuhn ve svých pozdějších pracích ostře napadá tzv. silný program sociologie vědění a důsledně se vůči němu vymezuje. Tato skutečnost je zajímavá z toho důvodu, že představitelé silného programu se naopak ke Kuhnovi otevřeně hlásí a vydatně čerpají z jeho díla, neboť v něm spatřují řadu klíčových myšlenek, které implikují možnost sociologické analýzy vědeckého poznání. Cílem této studie je kriticky přezkoumat Kuhnovu kritiku silného programu a zhodnotit její oprávněnost. V první části je za tímto účelem nejprve rekonstruováno Kuhnovo pojetí (...) silného programu, jež je posléze porovnáno s pracemi jeho zakladatelů Davida Bloora a Barryho Barnese, v nichž je silný program teoreticky rozvíjen. V další části jsou Kuhnovy argumenty proti silnému programu konfrontovány s vybranou historickou studií, v níž je silný program aplikován v praxi. Třetí část pak obrací pozornost ke Kuhnovu vlastnímu pojetí vědy, které je v ní porovnáno se silným programem právě v těch aspektech, jež na něm Kuhn kritizuje. (shrink)

How should one react when one has a belief, but knows that other people—who have roughly the same evidence as one has, and seem roughly as likely to react to it correctly—disagree? This paper argues that the disagreement of other competent inquirers often requires one to be much less confident in one’s opinions than one would otherwise be.

The question of whether Everettian quantum mechanics (EQM) justifies the existence of metaphysical indeterminacy has recently come to the fore. Metaphysical indeterminacy has been argued to emerge from three sources: coherent superpositions, the indefinite number of branches in the quantum multiverse and the nature of these branches. This paper reviews the evidence and concludes that those arguments don’t rely on EQM alone and rest on metaphysical auxiliary assumptions that transcend the physics of EQM. We show how EQM can be ontologically (...) interpreted without positing metaphysical indeterminacy by adopting a deflationary attitude towards branches. Two ways of developing the deflationary view are then proposed: one where branches are eliminated, and another where they are reduced to the universal quantum state. (shrink)

Hume’s criticisms of divine causation are insufficient because he does not respond to important philosophical positions that are defended by those whom he closely read. Hume’s arguments might work against the background of a Cartesian definition of body, or a Malebranchian conception of causation, or some defenses of occasionalism. At least, I will not here argue that they succeed or fail against those targets. Instead, I will lay out two major deficiencies in his arguments against divine causation. I call these (...) “deficiencies” because Hume does not adequately address live positions. This does not mean, of course, that there are not problems with these views or that Hume could not have given strong arguments against them. Rather, Hume’s arguments, which can seem comprehensive to the twenty-first century reader, are in fact not so. For the deficiencies discussed in this essay, I point to writers from Hume’s near context (many of whom we know he read carefully) who held the views not discussed, and I provide reasons why Hume seems not to have entertained these possibilities. I won’t distinguish between accidentally overlooking and actively ignoring. By drawing attention to these three deficiencies, I have two goals. The first is to demonstrate the diversity of seventeenth and early eighteenth century views on divine causation, especially among philosophers in England, Scotland, and Ireland, who are often ignored by philosophers today who, like Hume, focus on continental Cartesians while ignoring British dualists and vitalists. The second goal is to make today’s readers aware of shortcomings in Hume’s arguments to encourage productively contextual readings of Hume and his contemporaries. (shrink)

When our choice affects some other person and the outcome is unknown, it has been argued that we should defer to their risk attitude, if known, or else default to use of a risk avoidant risk function. This, in turn, has been claimed to require the use of a risk avoidant risk function when making decisions that primarily affect future people, and to decrease the desirability of efforts to prevent human extinction, owing to the significant risks associated with continued human (...) survival. I raise objections to the claim that respect for others’ risk attitudes requires risk avoidance when choosing for future generations. In particular, I argue that there is no known principle of interpersonal aggregation that yields acceptable results in variable population contexts and is consistent with a plausible ideal of respect for others’ risk attitudes in fixed population cases.

For well over a century the dominant narrative covering the major thinkers and themes of early modern British philosophy has been that of “British Empiricism”, within which the great triumvirate of Locke-Berkeley-Hume are taken to be the dominant figures. Although it is now common to question this schema as a way of analyzing and understanding the period in question, it continues to command considerable authority and acceptance. (One likely reason for this is that no credible or plausible alternatives structures or (...) schemas of analysis have suggested themselves.) Be this as it may, the analysis of the rival systems of Clarke, Berkeley and Hume makes clear that this narrative, however deeply entrenched it may be, is wholly misleading and both distorts and obscures key themes and figures in the period in question.

In his Enquiry concerning the Principles of Morals David Hume said that a group of earlier modern philosophers, beginning with Malebranche, held that morality was founded on relations. In this paper I follow up on that suggestion by investigating pre-Humean views in moral philosophy according to which morality is founded on relations. I do that by looking at the work of Nicolas Malebranche, John Locke, and Samuel Clarke. Each of them talked prominently about relations in their accounts of basic (...) aspects of morality. Beyond that, each of them turns out to have held both metaphysical and epistemological views that might be described as founding morality on relations. Despite the definite differences between the three philosophers’ approaches, Hume does seem to have noticed a genuine connection here—even though he himself tended to ignore significant versions of this approach when criticizing it.

This dialogue explores the question of whether intentionality—the “ofness”, “aboutness”, or “directedness” of mental states—is a relation. We explore three views: the Naive View, on which intentionality is a relation to ordinary, everyday objects, facts, and other such items; the Abstract Contents View, on which intentionality is a relation to mind-independent abstract entities that are our contents; and the Aspect View, on which intentionality is a matter of having intentional states with particular (non-relational) aspects that are our contents. We consider (...) the challenges facing these views, which include empirical challenges in accounting for all the contents our intentional states can represent, metaphysical challenges in making sense of how contents can be entertained or otherwise represented by us and how they can play a psychological role in the mental economy, and challenges in making sense of how intentionality connects us to the world—if at all. Along the way, we consider the question of how consciousness is related to intentionality and how this affects one’s choice of views. (shrink)

Does consciousness collapse the quantum wave function? This idea was taken seriously by John von Neumann and Eugene Wigner but is now widely dismissed. We develop the idea by combining a mathematical theory of consciousness (integrated information theory) with an account of quantum collapse dynamics (continuous spontaneous localization). Simple versions of the theory are falsified by the quantum Zeno effect, but more complex versions remain compatible with empirical evidence. In principle, versions of the theory can be tested by experiments with (...) quantum computers. The upshot is not that consciousness-collapse interpretations are clearly correct, but that there is a research program here worth exploring. (shrink)

Longtermism is the thesis that in a large class of decision situations, the best thing we can do is what is best for the long-term future. The scope question for longtermism asks: how large is the class of decision situations for which this is true? In this paper, I suggest that the scope of longtermism may be narrower than many longtermists suppose. I identify a restricted version of longtermism: swamping axiological strong longtermism (swamping ASL). I identify three scope-limiting factors - (...) probabilistic and decision-theoretic phenomena which, when present, tend to reduce the prospects for swamping ASL. I argue that these scope-limiting factors are often present in human decision problems, then use two case studies from recent discussions of longtermism to show how the scope-limiting factors lead to a restricted, if perhaps nonempty, scope for swamping ASL.

This article defends the view that having a language just is knowing how to engage in communication with it. It also argues that, despite claims to the contrary, this view is compatible and complementary with the Chomskyan conception of language on which humans have languages in virtue of being in brain states realizing tacit knowledge of grammars for those languages.

We present data and argument to show that in Tetris - a real-time interactive video game - certain cognitive and perceptual problems are more quickly, easily, and reliably solved by performing actions in the world rather than by performing computational actions in the head alone. We have found that some translations and rotations are best understood as using the world to improve cognition. These actions are not used to implement a plan, or to implement a reaction; they are used to (...) change the world in order to simplify the problem-solving task. Thus, we distinguish pragmatic actions ñ actions performed to bring one physically closer to a goal - from epistemic actions - actions performed to uncover information that is hidden or hard to compute mentally. To illustrate the need for epistemic actions, we first develop a standard information-processing model of Tetris-cognition, and show that it cannot explain performance data from human players of the game - even when we relax the assumption of fully sequential processing. Standard models disregard many actions taken by players because they appear unmotivated or superfluous. However, we describe many such actions that are actually taken by players that are far from superfluous, and that play valuable roles in improving human performance. We argue that traditional accounts are limited because they regard action as having a single function: to change the world. By recognizing a second function of action - an epistemic function - we can explain many of the actions that a traditional model cannot. Although, our argument is supported by numerous examples specifically from Tetris, we outline how the one category of epistemic action can be incorporated into theories of action more generally.

Representationalists argue that phenomenal states are intentional states of a special kind. This paper offers an account of the kind of intentional state phenomenal states are: I argue that they are underived intentional states.

This paper offers both a theoretical and an experimental perspective on the relationship between connectionist and Classical (symbol-processing) models. Firstly, a serious flaw in Fodor and Pylyshyn’s argument against connectionism is pointed out: if, in fact, a part of their argument is valid, then it establishes a conclusion quite different from that which they intend, a conclusion which is demonstrably false. The source of this flaw is traced to an underestimation of the differences between localist and distributed representation. It has (...) been claimed that distributed representations cannot support systematic operations, or that if they can, then they will be mere implementations of traditional ideas. This paper presents experimental evidence against this conclusion: distributed representations can be used to support direct structure-sensitive operations, in a man- ner quite unlike the Classical approach. Finally, it is argued that even if Fodor and Pylyshyn’s argument that connectionist models of compositionality must be mere implementations were correct, then this would still not be a serious argument against connectionism as a theory of mind.

The old evidence problem affects any probabilistic confirmation measure based on comparing pr(H/E) and pr(H).

To the extent that dualism is even taken to be a serious option in contemporary discussions of personal identity and the philosophy of mind, it is almost exclusively either Cartesian dualism or property dualism that is considered. The more traditional dualism defended by Aristotelians and Thomists, what I call hylemorphic dualism, has only received scattered attention. In this essay I set out the main lines of the hylemorphic dualist position, with particular reference to personal identity. First I argue that overemphasis (...) of the problem of consciousness has had an unhealthy effect on recent debate, claiming instead that we should emphasize the concept of form. Then I bring in the concept of identity by means of the notion of substantial form. I continue by analyzing the relation between form and matter, defending the traditional theses of prime matter and of the unicity of substantial form. I then argue for the immateriality of the substantial form of the human person, viz. the soul, from an account of the human intellect. From this follows the soul's essential independence of matter. Finally, although the soul is the immaterial bearer of personal identity, that identity is still the identity of an essentially embodied being. I explain how these ideas are to be reconciled. Footnotesa I am grateful to Stephen Braude, John Cottingham, John Haldane, David Jehle, Joel Katzav, Eduardo Ortiz, and Fred Sommers for helpful comments and discussion of a draft of this essay.

In this paper, we develop an account of the justification thinkers have for employing certain basic belief-forming methods. The guiding idea is inspired by Reichenbach's work on induction. There are certain projects in which thinkers are rationally required to engage. Thinkers are epistemically justified in employing any belief-forming method such that "if it doesn't work, nothing will" for successfully engaging in such a project. We present a detailed account based on this intuitive thought and address objections to it. We conclude (...) by commenting on the implications that our account may have for other important epistemological issues and debates. (shrink)

I argue that John Dewey’s analysis of imagination enables an account of learning from imaginary cases consistent with Jonathan Dancy’s moral particularism. Moreover, this account provides a more robust account of learning from cases than Dancy’s own. Particularism is the position that there are no, or at most few, true moral principles, and that competent reasoning and judgment do not require them. On a particularist framework, one cannot infer from an imaginary case that because a feature has a particular moral (...) importance there, that it must have that import in an actual case. Instead, for Dancy, cases can yield “reminders,” and a person with a lot of experience (real or imagined) brings a “checklist” of features that can matter to a situation. Using the Nathan-David exchange from 2 Samuel and Martha Nussbaum’s “Steerforth’s Arm” from Love’s Knowledge, I show that this account does not explain all instances of learning from cases. Drawing on recent work on cases, I argue that cases can be educative by serving an exploratory function, probing what one takes to be known and provoking change in the background one uses in evaluating a situation. I then argue that Dewey’s work on imagination in his comments on sympathy and in A Common Faith and Art as Experience enables such a role for cases on a particularist framework. Mark Johnson’s recent work on metaphor further illuminates how Dewey’s account of art can be exploratory. I contend that this account affords an exploratory role for cases consistent with Dancy’s particularism. (shrink)

There are two versions of the language-of-thought hypothesis (LOT): Representational LOT (roughly, structured representation), introduced by Ockham, and computational LOT (roughly, symbolic computation) introduced by Fodor. Like many others, I oppose the latter but not the former. Quilty-Dunn et al. defend representational LOT, but they do not defend the strong computational LOT thesis central to the classical-connectionist debate.

Consequentialism, many philosophers have claimed, asks too much of us to be a plausible ethical theory. Indeed, the theory's severe demandingness is often claimed to be its chief flaw. My thesis is that as we come to better understand this objection, we see that, even if it signals or tracks the existence of a real problem for Consequentialism, it cannot itself be a fundamental problem with the view. The objection cannot itself provide good reason to break with Consequentialism, because it (...) must presuppose prior and independent breaks with the view. The way the objection measures the demandingness of an ethical theory reflects rather than justifies being in the grip of key anti-Consequentialist conclusions. We should reject Consequentialism independently of the Objection or not at all. Thus, we can reduce by one the list of worrisome fundamental complaints against Consequentialism. (shrink)

The principle of alternate possibilities (PAP), making the ability to do otherwise a necessary condition for moral responsibility, is supposed by Harry Frankfurt, John Fischer, and others to succumb to a peculiar kind of counterexample. The paper reviews the main problems with the counterexample that have surfaced over the years, and shows how most can be addressed within the terms of the current debate. But one problem seems ineliminable: because Frankfurt''s example relies on a counterfactual intervener to preclude alternatives to (...) the person''s action, it is not possible for it to preclude all alternatives (intervention that is contingent upon a trigger cannot bring it about that the trigger never occurred). This makes it possible for the determined PAPist to maintain that some pre-intervention deviation is always available to ground moral responsibility. In reply, the critic of PAP can examine all the candidate deviations and argue their irrelevance to moral responsibility (a daunting prospect); or the critic can dispense with counterfactual intervention altogether. The paper pursues the second of these strategies, developing three examples of noncounterfactual intervention in which (i) the agent has no alternatives (and a fortiori no morally relevant alternatives), yet (ii) there is just as much reason to think that the agent is morally responsible as there was in Frankfurt''s original example. The new counterexamples do suffer from one liability, but this is insufficient in the end to repair PAP''s conceptual connection between moral responsibility and alternate possibilities. (shrink)

Inspired by Rudolf Carnap's Der Logische Aufbau Der Welt, David J. Chalmers argues that the world can be constructed from a few basic elements. He develops a scrutability thesis saying that all truths about the world can be derived from basic truths and ideal reasoning. This thesis leads to many philosophical consequences: a broadly Fregean approach to meaning, an internalist approach to the contents of thought, and a reply to W. V. Quine's arguments against the analytic and the a (...) priori. Chalmers also uses scrutability to analyze the unity of science, to defend a conceptual approach to metaphysics, and to mount a structuralist response to skepticism. Based on the 2010 John Locke lectures, Constructing the World opens up debate on central philosophical issues involving language, consciousness, knowledge, and reality. This major work by a leading philosopher will appeal to philosophers in all areas. This entry contains uncorrected proofs of front matter, chapter 1, and first excursus. (shrink)

A wide range of prominent epistemological theories include a principle of conservatism. Such principles take the fact that an agent currently holds a certain belief to constitute at least some measure of epistemic justification for her to maintain that belief. I examine the main arguments that have been made in conservatism's behalf, and find them unsound. Most interestingly, conservatism does not fall out of confirmational holism (the view that the justification of each of our beliefs is in part determined by (...) our other beliefs). I argue that conservatism is a mild form of dogmatism, and should be abandoned. (shrink)

Much recent discussion in the philosophy of mathematics has concerned the indispensability argument—an argument which aims to establish the existence of abstract mathematical objects through appealing to the role that mathematics plays in empirical science. The indispensability argument is standardly attributed to W. V. Quine and Hilary Putnam. In this paper, I show that this attribution is mistaken. Quine's argument for the existence of abstract mathematical objects differs from the argument which many philosophers of mathematics ascribe to him. Contrary to (...) appearances, Putnam did not argue for the existence of abstract mathematical objects at all. I close by suggesting that attention to Quine and Putnam's writings reveals some neglected arguments for platonism which may be superior to the indispensability argument. (shrink)
