Newtonian forces are pushes and pulls, possessing magnitude and direction, that are exerted (in the first instance) by objects, and which cause (in particular) motions. I defend Newtonian forces against the four best reasons for denying or doubting their existence. A running theme in my defense of forces will be the suggestion that Newtonian Mechanics is a special science, and as such has certain prima facie ontological rights and privileges, that may be maintained against various challenges.

Explaining moral intuitions is one of the hot topics of recent cognitive science. In the present article we focus on a factor that attracted surprisingly little attention so far, namely the temporal order in which moral scenarios are presented. We argue that previous research points to a systematic pattern of order effects that has been overlooked until now: only judgments of actions that are normally regarded as morally acceptable are susceptible to be affected by the order of presentation, and this (...) in turn is only the case if the dilemma is immediately preceded by a dilemma in which the proposed action was considered as not morally acceptable. We conducted an experiment that largely confirmed this pattern and allowed us to analyze by what individual level responses it was generated. We argue that investigating order effects is necessary for approaching a complete descriptive moral theory. Furthermore, we discuss the implications of these findings for moral philosophy. (shrink)

A growing body of empirical literature challenges philosophers’ reliance on intuitions as evidence based on the fact that intuitions vary according to factors such as cultural and educational background, and socio-economic status. Our research extends this challenge, investigating Lehrer’s appeal to the Truetemp Case as evidence against reliabilism. We found that intuitions in response to this case vary according to whether, and which, other thought experiments are considered first. Our results show that compared to subjects who receive the Truetemp Case (...) first, subjects first presented with a clear case of knowledge are less willing to attribute knowledge in the Truetemp Case, and subjects first presented with a clear case of nonknowledge are more willing to attribute knowledge in the Truetemp Case. We contend that this instability undermines the supposed evidential status of these intuitions, such that philosophers who deal in intuitions can no longer rest comfortably in their armchairs.

Using empirical evidence to attack intuitions can be epistemically dangerous, because various of the complaints that one might raise against them (e.g., that they are fallible; that we possess no non-circular defense of their reliability) can be raised just as easily against perception itself. But the opponents of intuition wish to challenge intuitions without at the same time challenging the rest of our epistemic apparatus. How might this be done? Let us use the term “hopefulness” to refer to the extent (...) to which we possess a good capacity for the detection and correction of the errors of any fallible source of evidence. I argue that we should not trust putative sources of evidence that are substantially lacking in hopefulness (even if they are basically reliable), and that we are indeed already operating under such a norm in our ordinary and scientific practices. I argue further that the philosophical practice of the appeal to intuitions is, in these terms, badly hopeless... (shrink)

This essay defends a version of the Doctrine of Double Effect (DDE) – the doctrine that there is normally a stronger reason against an act that has a bad state of affairs as one of its intended effects than against an otherwise similar act that has that bad state of affairs as an unintended effect. First, a precise account of this version of the DDE is given. Secondly, some suggestions are made about why we should believe the DDE, and about (...) why it is true. Finally, a solution is developed to the so-called ‘closeness problem’ that any version of the DDE must face. (shrink)

In this paper we discuss an approach called grounded action cognition, which aims to provide a theory of the interdependencies between motor control and action-related cognitive processes, like perceiving an action or thinking about an action. The theory contrasts with traditional views in cognitive science in that it motivates an understanding of cognition as embodied, through application of Barsalou’s general idea of grounded cognition. To guide further research towards an appropriate theory of grounded action cognition we distinguish between grounding qua (...) acquisition and grounding qua constitution. On this basis, we distinguish three possible theoretical conceptions of grounded action cognition. In addition to these methodological and conceptual analyses, we draw on recent empirical evidence to motivate our inclination towards a particular theory. According to this theory certain representations are involved in action cognition and action perception that are not modality-specific as usually proposed by advocates of grounded cognition. Further, the evidence is in favor of our more specific theory stating that for some cognitive abilities, some motor abilites are constitutive. (shrink)

My concern in this paper will be to explore and develop a version of nonsocratic skepticism about weakness of will. In my view, socratism is incorrect, but like Socrates, I think that the common understanding of weakness of will raises serious problems. Contrary to socratism, it is possible for a person knowingly to act contrary to his or her better judgment. But this description does not exhaust the common view of weakness. Also implicit in this view is the belief that (...) actions which are contrary to one's better judgment are free in the sense that the agent could have done otherwise. To take seriously the possibility of acting contrary to one's better judgment is at the same time to raise problems about the distinction between weakness and compulsion. I argue that the common view, according to which the differentiating feature is that the weak are able to conform their behavior to their practical judgments, is unjustified. Instead, I have proposed that weakness of will involves the failure to develop certain normal capacities of self-control, whereas compulsion involves desires which even the possession of such capacities would not enable one to resist.

If there is a moral reason for A to do X, and if A cannot do X without doing Y, and if doing Y will enable A to do X, then there is a moral reason for A to do Y. This principle is plausible but mysterious, so it needs to be explained. It can be explained by necessary enabler consequentialism, but not by other consequentialisms or any deontological moral theory. Or so I argue. Frances Howard-Snyder objects that this argument (...) fails to establish consequentialism as understood by, because it fails to establish agent-neutrality. I respond by distinguishing consequentialism, which need not be agent-neutral, from utilitarianism, which claims agent-neutrality. Howard-Snyder also presents a schema for a non-consequentialist theory that is supposed to explain moral substitutability. I respond that her explanation cannot be completed without introducing incoherence into deontological moral theories. (shrink)

The comparator-model, originally developed to explain motor action, has recently been invoked to explain several aspects of the self. However, in the first place it may not be used to explain a basic self-world distinction because it presupposes one. Our alternative account is based on specific systematic covariation between action and perception. Secondly, the comparator model cannot explain the feeling of ownership of thoughts. We argue—contra Frith and Campbell—that thoughts are not motor processes and therefore cannot be described by the (...) comparator-model. Rather, thoughts can be the triggering cause (intention) for actions. An alternative framework for the explanation of thought insertion in schizophrenics is presented. (shrink)

The aim of this paper is twofold: (i) to introduce the framework of update semantics and to explain what kind of semantic phenomena may successfully be analysed in it: (ii) to give a detailed analysis of one such phenomenon: default reasoning.

Donald VanDeVeer probes the moral complexities of the question: under what conditions is it permissible to intervene invasively in the lives of competent persons--for example, by deception, force, or coercive threat--for their own good? In a work with broad significance for law, public policy, professional-client relations, and private interactions, he presents a theory of an autonomy-respecting" paternalism.

In lieu of an abstract, here is a brief excerpt of the content:Peter van Inwagen FICTION AND METAPHYSICS Many works of fiction address themselves directly to metaphysiced issues. One thinks of the stories of Olaf Stapledon, Charles Williams, or Jorge Luis Borges. Other fiction is more subtly and indirectly related to metaphysics — A la recherche du temps perdu, for exeimple, or, in a radier different way, some science fiction. The relations that various novels and stories bear to the questions (...) ofmetaphysics would be an interesting topic, but it is not the topic of the present article, which is the relevance to metaphysics not of this or that work, but ramer of the very existence of such a thing as fiction. We shall see mat philosophical reflection on fiction can lead one to certain remarkable metaphysical conclusions. Not surprisingly, the area of metaphysics to which these conclusions pertain is ontology. The word, though not the study it represents, is a new one — it is probably a seventeenth-century coinage. In the present century, the word "ontology" is associated mainly with the names of Heidegger and Quine. I shall be using the word in Quine's sense: as a name for the study that attempts to answer the question, What is there? Quine's contributions to this study are of central importance for the thesis of this article. These contributions may be divided into two parts: those that belong to ontology proper and those that belong to what we may call meta-ontology. By Quine's "ontology proper," I mean his actual attempt to answer the question, What is there? This attempt is of great intrinsic interest, but it is not relevetnt to my topic. By Quine's meta-ontology, I mean his feunous discussion of what it is to ask what there is emd his famous dieses about how to approach mis question.1 These theses are the product of a really remarkable effort to think clearly about questions almost no one had thought cleeirly about, and a proper appreciation of them will liberate one from some very old and very strong illusions about being emd existence. Or so many philosophers, including the present author, would say. And yet Quine's meta-ontology, when it is combined with what seem to be some very simple emd obvious facts about fiction, yields a result mat seems just obviously wrong: that names drawn from works of fiction ("Mr. Pickwick" emd "Tom Sawyer," for example, as well as proper names of odier sorts, such as "Dotheboys Hall" and "Barchester") denote existent objects. The thesis of this 67 68PHILOSOPHY AND LITERATURE article is mat this consequence of Quine's meta-ontology does not constitute a reductio ad absurdum; radier, Quine's meta-ontology should be retained and mis consequence accepted. I shall first examine Quine's meta-ontology in the abstract, and then in application to fiction. In the abstract, Quine's meta-ontology may be viewed as comprising four propositions. (1)Being is die seune as existence. That is, to say mat things of a certain sort exist emd to say mat there être things of diat sort is to say pretty much the same diing. For example, to say diat horses exist is to say mere are horses, and to say mat diere was such a person as Homer is to say that Homer existed. This might seem obvious, but on reflection it can seem less obvious. Suppose I am discussing someone's delusions and I say, "There are a lot of diings he believes in that do not exist." On die face of it, I appear to be saying diat diere are diings — the poison in his drink, his uncle's medice, emd so on — that do not exist. To tedce a radier more metaphysical example, I have read a letter to the editor of a newspaper, the audior of which argues diat contraception is a sin since it prevents people who would omerwise exist from doing so. This may be a bad argument on meiny grounds that have nothing to do with metaphysics, but it is certainly clear diat its propounder believes diat diere are unconceived people, people who might have existed but who, owing to certain acts of contraception, do not exist...

"This is an important book, and no one interested in issues which touch on the free will will want to ignore it."--Ethics. In this stimulating and thought-provoking book, the author defends the thesis that free will is incompatible with determinism. He disputes the view that determinism is necessary for moral responsbility. Finding no good reason for accepting determinism, but believing moral responsiblity to be indubitable, he concludes that determinism should be rejected.

Despite its familiarity and widespread acceptance, the concept of “brain death” remains incoherent in theory and confused in practice. Moreover, the only purpose served by the concept is to facilitate the procurement of transplantable organs. By abandoning the concept of brain death and adopting different criteria for organ procurement, we may be able to increase both the supply of transplantable organs and clarity in our understanding of death.

A recent study of moral intuitions, performed by Joshua Greene and a group of researchers at Princeton University, has recently received a lot of attention. Greene and his collaborators designed a set of experiments in which subjects were undergoing brain scanning as they were asked to respond to various practical dilemmas. They found that contemplation of some of these cases (cases where the subjects had to imagine that they must use some direct form of violence) elicited greater activity in certain (...) areas of the brain associated with emotions compared with the other cases. It has been argued (e.g., by Peter Singer) that these results undermine the reliability of our moral intuitions, and therefore provide an objection to methods of moral reasoning that presuppose that they carry an evidential weight (such as the idea of reflective equilibrium). I distinguish between two ways in which Greene's findings lend support for a sceptical attitude towards intuitions. I argue that, given the first version of the challenge, the method of reflective equilibrium can easily accommodate the findings. As for the second version of the challenge, I argue that it does not so much pose a threat specifically to the method of reflective equilibrium but to the idea that moral claims can be justified through rational argumentation in general.

Jeremy Gwiazda made two criticisms of my formulation in terms of Bayes’s theorem of my probabilistic argument for the existence of God. The first criticism depends on his assumption that I claim that the intrinsic probabilities of all propositions depend almost entirely on their simplicity; however, my claim is that that holds only insofar as those propositions are explanatory hypotheses. The second criticism depends on a claim that the intrinsic probabilities of exclusive and exhaustive explanatory hypotheses of a phenomenon must (...) sum to 1; however it is only those probabilities plus the intrinsic probability of the non-occurrence of the phenomenon which must sum to 1.

I begin by proposing and explicating a plausible articulation of the view that morality is overriding. I then argue that it would be desirable for this thesis to be sustained. However, the prospects for its vindication will depend crucially on which moral theory we adopt. I examine some schematic moral theories in order to bring out which are friendly and which unfriendly to moral overridingness. In light of the reasons to hope that the overridingness thesis can be sustained, theories apparently (...) incompatible with it – I argue that consequentialism is one – have a count against them.

Contemporary realist theories of value claim to be compatible with natural science. In this paper, I call this claim into question by arguing that Darwinian considerations pose a dilemma for these theories. The main thrust of my argument is this. Evolutionary forces have played a tremendous role in shaping the content of human evaluative attitudes. The challenge for realist theories of value is to explain the relation between these evolutionary influences on our evaluative attitudes, on the one hand, and the (...) independent evaluative truths that realism posits, on the other. Realism, I argue, can give no satisfactory account of this relation. On the one hand, the realist may claim that there is no relation between evolutionary influences on our evaluative attitudes and independent evaluative truths. But this claim leads to the implausible skeptical result that most of our evaluative judgements are off track due to the distorting pressure of Darwinian forces. The realist’s other option is to claim that there is a relation between evolutionary influences and independent evaluative truths, namely that natural selection favored ancestors who were able to grasp those truths. But this account, I argue, is unacceptable on scientific grounds. Either way, then, realist theories of value prove unable to accommodate the fact that Darwinian forces have deeply influenced the content of human values. After responding to three objections, the third of which leads me to argue against a realist understanding of the disvalue of pain, I conclude by sketching how antirealism is able to sidestep the dilemma I have presented. Antirealist theories of value are able to offer an alternative account of the relation between evolutionary forces and evaluative facts —
an account that allows us to reconcile our understanding of evaluative truth with our understanding of the many non-rational causes that have played a role in shaping our evaluative judgements. (shrink)

Here is a simple counterexample to David Lewis’s causal influence account of causation, one that is especially illuminating due to its connection to what Lewis himself writes: it is a variant of his trumping example.

A phenomenal concept is the concept of a particular type of sensory or perceptual experience, where the notion of experience is understood phenomenologically. A recent and increasingly influential idea in philosophy of mind suggests that reflection on these concepts will play a major role in the debate about conscious experience, and in particular in the defense of physicalism, the thesis that psychological truths supervene on physical truths. According to this idea—I call it the phenomenal concept strategy —phenomenal concepts are importantly (...) different from other concepts, and arguments against physicalism fatally neglect to take this difference into account. This paper divides the phenomenal concept strategy into a number of different versions, and argues that no version of the strategy is successful. The paper ends by contrasting the phenomenal concept strategy with a rival strategy—I call it the missing concept strategy . I suggest that the missing concept strategy presents a more plausible response to the issues about physicalism and experience. (shrink)

Jason Stanley's "Knowledge and Practical Interests" is a brilliant book, combining insights about knowledge with a careful examination of how recent views in epistemology fit with the best of recent linguistic semantics. Although I am largely convinced by Stanley's objections to epistemic contextualism, I will try in what follows to formulate a version that might have some prospect of escaping his powerful critique.

The paper builds on the basically Humean idea that A is a cause of B iff A and B both occur, A precedes B, and A raises the metaphysical or epistemic status of B given the obtaining circumstances. It argues that in pursuit of a theory of deterministic causation this ‘status raising’ is best explicated not in regularity or counterfactual terms, but in terms of ranking functions. On this basis, it constructs a rigorous theory of deterministic causation that successfully deals (...) with cases of overdetermination and pre-emption. It finally indicates how the account's profound epistemic relativization induced by ranking theory can be undone.

This article provides a critical introduction to contractualism as a moral or ethical theory, that is, as a theory of the rightness and wrongness of individual conduct – focusing specifically on the influential 'Kantian' version of contractualism due to T. M. Scanlon. I begin by elucidating the key features of Scanlon's contractualism: justifiability to others; reasonable rejectability; the individualist restriction; and mutual recognition. I then turn to discuss both its appeal and the main objections that have been raised to it (...) – objections concerning our duties to the cognitively limited and impaired, aggregation, demandingness, normativity and explanatory adequacy. I conclude by mentioning some contractualist alternatives to Scanlon's theory. (shrink)

Ernest Sosa presents a new approach to the problems of knowledge and scepticism. He argues for two levels of knowledge, the animal and the reflective, each viewed as a distinctive human accomplishment. Sosa's virtue epistemology illuminates different varieties of scepticism, the nature and status of intuitions, and epistemic normativity.

Ernest Sosa's A Virtue Epistemology, Vol. I is arguably the single-most important monograph to be published in analytic epistemology in the last ten years. Sosa, the first in the field to employ the notion of intellectual virtue – in his ground-breaking ‘The Raft and the Pyramid’– is the leading proponent of reliabilist versions of virtue epistemology. In A Virtue Epistemology, he deftly defends an externalist account of animal knowledge as apt belief, argues for a distinction between animal and reflective knowledge, (...) contends that rational intuition is an intellectual virtue ; and offers responses to dream scepticism, the problem of the criterion and the value problem. Nearly all of these arguments are new, albeit consistent with Sosa's earlier work; that is, consistent with two notable exceptions. First, c ontra Sosa's ‘Replies’ in Ernest Sosa and His Critics, A Virtue Epistemology explicitly contends that safety is not required for animal knowledge. Second, unlike Sosa's Knowledge in Perspective, which arguably construes the intellectual virtues as merely instrumentally valuable, A Virtue Epistemology explicitly contends that the intellectual virtues are instrumentally and constitutively valuable. Best read in conjunction with the above monographs and Epistemic Justification, A Virtue Epistemology is mandatory reading for epistemologists and graduate students in the field. It will rightly set the standard for debates in analytic epistemology for years to come.I will summarize and raise objections to two key conclusions that are unique to A Virtue Epistemology: the ‘kaleidoscope-perceiver’ has animal knowledge but lacks reflective knowledge; unlike the k-perceiver, the ordinary perceiver has reflective knowledge. My objections …. (shrink)

Islamic building codes require mosques to face Mecca. The further Islam spreads, the more apt are believers to fall into a quandary. X faces Y only when the front of X is closer to Y than any other side of X. So the front of the mosque should be oriented along a shortest path to Mecca. Which way is that? Does the path to Mecca tunnel through the earth? Or does the path follow the surface of the earth?

Sorensen presents a general theory of thought experiments: what they are, how they work, what are their virtues and vices. On Sorensen's view, philosophy differs from science in degree, but not in kind. For this reason, he claims, it is possible to understand philosophical thought experiments by concentrating on their resemblance to scientific relatives. Lessons learned about scientific experimentation carry over to thought experiment, and vice versa. Sorensen also assesses the hazards and pseudo-hazards of thought experiments. Although he grants that (...) there are interesting ways in which the method leads us astray, he attacks most scepticism about thought experiments as arbitrary. They should be used, he says, as they generally are used--as part of a diversified portfolio of techniques. All of these devices are individually susceptible to abuse, fallacy, and error. Collectively, however, they provide a network of cross-checks that make for impressive reliability. (shrink)

Part one attempts to diffuse five different forms of truth skepticism, broadly conceived: the view that truth is indefinable, that it is unknowable, that it is inextricably metaphysical, that there is no such thing as truth, and the view that truth is inherently paradoxical, and so must either be abandoned, or revised. An intriguing formulation of the last of these views is due to Alfred Tarski, who argued that the Liar paradox shows natural languages to be inconsistent because they contain (...) defective, and ultimately incoherent, truth predicates. I argue in response that on a plausible interpretation of his puzzling notion of an inconsistent language, Tarski’s argument turns out to be logically valid, but almost certainly unsound, since one of its premises can be seen to be indefensible. Similar results are achieved for other forms of truth skepticism. (shrink)

Wittgenstein's remarks about family resemblance in the Philosophical Investigations should not be construed as implying a comprehensive theory of universals. They possess, rather, a defensive function in his exposition. The remarks allow one, nevertheless, to draw certain general conclusions about how Wittgenstein thought about concepts. Reflection on the notion of family resemblance reveals that kinship and similarity considerations intersect in it in a problematic fashion.

Distinctions have been proposed between systems of reasoning for centuries. This article distills properties shared by many of these distinctions and characterizes the resulting systems in light of recent findings and theoretical developments. One system is associative because its computations reflect similarity structure and relations of temporal contiguity. The other is "rule based" because it operates on symbolic structures that have logical content and variables and because its computations have the properties that are normally assigned to rules. The systems serve (...) complementary functions and can simultaneously generate different solutions to a reasoning problem. The rule-based system can suppress the associative system but not completely inhibit it. The article reviews evidence in favor of the distinction and its characterization. (shrink)

This paper argues that normative claims are truth‐apt contents of cognition – propositions about what there is reason to believe, to do or to feel – but that their truth is not a matter of correspondence or representation. We do not have to choose between realism about the normative and non‐cognitivism about it. The universality of reasons, combined with the spontaneity of normative responses, suffices to give normative claims the distinctive link to a ‘convergence commitment’ which characterises any genuine judgement; (...) an accurate epistemology of normative discourse need postulate no faculty of receptivity to a special domain of normative fact. Some general arguments for the view that cognitivism about a domain of discourse imposes realism about it are considered and rejected. (shrink)
