Looking back on it, it seems almost incredible that so many equally educated, equally sincere compatriots and contemporaries, all drawing from the same limited stock of evidence, should have reached so many totally different conclusions---and always with complete certainty.

In this paper, I explore the relationship between epistemic rationality and instrumental rationality, and I attempt to delineate their respective roles in typical instances of theoretical reasoning. My primary concern is with the instrumentalist conception of epistemic rationality: the view that epistemic rationality is simply a species of instrumental rationality, viz. instrumental rationality in the service of one's cognitive or epistemic goals. After sketching the relevance of the instrumentalist conception to debates over naturalism and 'the ethics of belief', I argue (...) that, despite enjoying considerable popularity among both epistemologists and philosophers of science, it is ultimately indefensible. Having thus argued for the distinctness of epistemic and instrumental rationality, I attempt to clarify the role played by each in typical instances of theoretical reasoning. I suggest that being theoretically rational--that is, being proficient with respect to theoretical reasoning--is best construed as a hybrid virtue, inasmuch as it involves manifesting sensitivity to two very different kinds of reasons.

Opponents of biomedical enhancement often claim that, even if such enhancement would benefit the enhanced, it would harm others. But this objection looks unpersuasive when the enhancement in question is a moral enhancement — an enhancement that will expectably leave the enhanced person with morally better motives than she had previously. In this article I (1) describe one type of psychological alteration that would plausibly qualify as a moral enhancement, (2) argue that we will, in the medium-term future, probably be (...) able to induce such alterations via biomedical intervention, and (3) defend future engagement in such moral enhancements against possible objections. My aim is to present this kind of moral enhancement as a counter-example to the view that biomedical enhancement is always morally impermissible. (shrink)

The concept of evidence is central to both epistemology and the philosophy of science. Of course, ‘evidence’ is hardly a philosopher's term of art: it is not only, or even primarily, philosophers who routinely speak of evidence, but also lawyers and judges, historians and scientists, investigative journalists and reporters, as well as the members of numerous other professions and ordinary folk in the course of everyday life. The concept of evidence would thus seem to be on firmer pre-theoretical ground than (...) various other concepts which enjoy similarly central standing within philosophy. (Contrast, for example, the epistemologist's quasi-technical term ‘epistemic justification’.). (shrink)

Suppose that you and I disagree about some non-straightforward matter of fact (say, about whether capital punishment tends to have a deterrent effect on crime). Psychologists have demonstrated the following striking phenomenon: if you and I are subsequently exposed to a mixed body of evidence that bears on the question, doing so tends to increase the extent of our initial disagreement. That is, in response to exactly the same evidence, each of us grows increasingly confident of his or her original (...) view; we thus become increasingly polarized as our common evidence increases. I consider several alternative models of how people reason about newly-acquired evidence which seems to disconfirm their prior beliefs. I then explore the normative implications of these models for the phenomenon in question. (shrink)

Few moral questions have greater bearing on the conduct of our everyday lives than questions about the morality of lying. These questions are also important for ethical theory. An important test of any theory of right and wrong is whether it gives an adequate account of the morality of lying. Conceptual questions about the nature of lying are prior to questions about the moral status of lying. Any theory about the moral status of lying presupposes an account of what lying (...) is.

The definition of art is controversial in contemporary philosophy. Whether art can be defined has also been a matter of controversy. The philosophical usefulness of a definition of art has also been debated. -/- Contemporary definitions can be classified with respect to the dimensions of art they emphasize. One distinctively modern, conventionalist, sort of definition focuses on art’s institutional features, emphasizing the way art changes over time, modern works that appear to break radically with all traditional art, the relational properties (...) of artworks that depend on works’ relations to art history, art genres, etc. – more broadly, on the undeniable heterogeneity of the class of artworks. The more traditional, less conventionalist sort of definition defended in contemporary philosophy makes use of a broader, more traditional concept of aesthetic properties that includes more than art-relational ones, and puts more emphasis on art’s pan-cultural and trans-historical characteristics – in sum, on commonalities across the class of artworks. Hybrid definitions aim to do justice to both the traditional aesthetic dimension as well as to the institutional and art-historical dimensions of art, while privileging neither. (shrink)

In a series of recent papers, Walter Sinnott-Armstrong has used findings in social psychology to put pressure on the claim that our moral beliefs can be non-inferentially justified. More specifically, he has suggested that insofar as our moral intuitions are subject to what psychologists call framing effects, this poses a real problem for moral intuitionism. In this paper, we are going to try to add more fuel to the empirical fire that Sinnott-Armstrong has placed under the feet of the intuitionist. (...) Along the way, we first provide an overview of what Sinnott-Armstrong calls the Master Argument against intuitionism. Then we examine some of the literature on framing effects—especially as it pertains to moral philosophy. Finally, we present the results of a new study which create yet another hurdle intuitionists must clear if they want to motivate their view. It appears that in addition to being influenced by framing effects, our moral intuitions are also influenced by an actor–observer bias as well—a bias whereby we hold other people to different moral standards than we would hold ourselves even if we were in the same situation. If we’re right, the burden is on the moral intuitionist to explain why we should have faith in our moral intuitions despite the gathering evidence concerning their seeming unreliability. And by our lights, this is something that simply cannot be done from the armchair. (shrink)

Ontology is the philosophical discipline that tries to find out what there is: what entities make up reality, what is the stuff the world is made from? Thus, ontology is part of metaphysics, and in fact it seems to be about half of all of metaphysics. It tries to establish what (kinds of) things there are, the other half tries to find out what the (general) properties of these things are and what (general) relations they have to each other. Settling (...) questions in ontology would bring with it major progress in metaphysics. And it would bring with it major progress in a variety of areas in philosophy outside of metaphysics as well. Many philosophical debates outside of metaphysics are quite directly influenced by how things turn out in ontology. Whether or not there are certain entities will give rise to quite different answers in various philosophical debates. I would like to very briefly describe three debates where ontological questions play a central role. These debates are either directly from metaphysics or from other areas of philosophy and they will be of central importance throughout this paper. (shrink)

In this paper I argue that internalistic foundationalist theories of the justification of memory belief are inadequate. Taking a discussion of John Pollock as a starting point, I argue against any theory that requires a memory belief to be based on a phenomenal state in order to be justified. I then consider another version of internalistic foundationalism and claim that it, too, is open to important objections. Finally, I note that both varieties of foundationalism fail to account for the epistemic (...) status of our justified nonoccurrent beliefs, and hence are drastically incomplete. (shrink)

Contemporary philosophical and scienti .c discussions of mind developed from a 'proto-concept of mind ',a mythical,tradition- alistic,animistic and quasi-sensory theory about what it means to have a mind. It can be found in many di .erent cultures and has a semantic core corresponding to the folk-phenomenological notion of a 'soul '.It will be argued that this notion originates in accurate and truthful .rst-person reports about the experiential content of a special neurophenomenological state-class called 'out-of-body experiences '.They can be undergone by (...) every human being and seem to possess a culturally invariant cluster of functional and phenomenal core properties similar to the proto-concept of mind. The common causal factor in the emergence and development of the notion of the soul and the proto-concept of mind may consist in a yet to be determined set of properties realized by the human brain, underlying the cluster of phenomenal properties described in the relevant first-person reports. This hypothesis suggests that such a neurofunctional substrate ed human beings at different times, and in widely varying cultural contexts, to postulate the existence of a soul and to begin developing a theory of mind.

If you are more likely to continue a course of action in virtue of having previously invested in that course of action, then you tend to honor sunk costs. It is widely thought both that (i) individuals often do give some weight to sunk costs in their decision-making and that (ii) it is irrational for them to do so. In this paper I attempt to cast doubt on the conventional wisdom about sunk costs, understood as the conjunction of these two (...) claims. (shrink)

Three-dimensionalists , sometimes referred to as endurantists, think that objects persist through time by being “wholly present” at every time they exist. But what is it for something to be wholly present at a time? It is surprisingly difficult to say. The threedimensionalist is free, of course, to take ‘is wholly present at’ as one of her theory’s primitives, but this is problematic for at least one reason: some philosophers claim not to understand her primitive. Clearly the three-dimensionalist would be (...) better off if she could state her theory in terms accessible to all. We think she can. What is needed is a definition of ‘is wholly present at’ that all can understand. in this paper, we offer one. (shrink)

The main objective of immunology is to establish why and when an immune response occurs, that is, to determine a criterion of immunogenicity. According to the consensus view, the proper criterion of immunogenicity lies in the discrimination between self and nonself. Here we challenge this consensus by suggesting a simpler and more comprehensive criterion, the criterion of continuity. Moreover, we show that this criterion may be considered as an interpretation of the immune 'self'. We conclude that immunologists can continue to (...) speak of the self, provided that they admit that the self/nonself discrimination is not an adequate criterion of immunogenicity. (shrink)

Michael Slote has defended a moral view that he calls "satisficing consequentialism." Less demanding than maximizing consequentialism, it requires only that agents bring about consequences that are "good enough." I argue that Slote's characterization of satisficing is ambiguous. His idea of consequences' being "good enough" admits of two interpretations, with different implications in (some) particular cases. One interpretation I call "absolute-level" satisficing, the other "comparative" satisficing. Once distinguished, these versions of satisficing appear in a very different light. Absolute-level satisficing is (...) indeed plausible and attractive, at least for subjective-good versions of consequentialism; comparative satisficing is not. (shrink)

This discussion recounts the development of several anthropological definitions of human nature. It then examines conclusions of studies in other disciplines that make possible a revised empirical definition of human nature and which have led to re-examination of paleoanthropological data classed as unimportant under the rubrics of preceeding studies. Finally, this discussion appraises certain of these data, as they pertain to the question: "Do empirical evidences suggest that a human nature, as well as a human structure, may be the product (...) of evolutionary processes?".

A number of important philosophical problems are problems in the overlap of logic and ontology. Both logic and ontology are diverse fields within philosophy, and partly because of this there is not one single philosophical problem about the relation between logic and ontology. In this survey article we will first discuss what different philosophical projects are carried out under the headings of "logic" and "ontology" and then we will look at several areas where logic and ontology overlap.

Definitions of the term gene typically superimpose molecular genetics onto Mendelism. What emerges are persistent attempts to regard the gene as a unit of structure and/or function, language that creates multiple meanings for the term and fails to acknowledge the diversity of gene architecture. I argue that coherence at the molecular level requires abandonment of the classical unit concept and recognition that a gene is constructed from an assemblage of domains. Hence, a domain set (1) conforms more closely to empirical (...) evidence for genetic organization of DNA regions capable of transcription and (2) has ontological properties lacking in the traditional unit definition.

G.E. Moore's Principia Ethica of 1903 is often considered a revolutionary work that set a new agenda for 20 th-century ethics. This historical view is hard to sustain, however. In metaethics Moore's non naturalist position was close to that defended by Henry Sidgwick and other late..

This essay is a commentary upon "Race and Kant" by Thomas Hill, Jr and Bernard Boxill. They argue that although Kant in his anthropological writings took blacks to be inferior, his moral theory requires that they be shown the proper moral respect since blacks are persons nonetheless. I argue that this argument is sound, because the conception of inferiority that Kant attributed to blacks does not permit showing them the proper moral respect. Imagine a defective Mercedes Benz and a (...) Ford Pinto. These two cars are not inferior in the same sort of way. For Kant, I argue, the inferiority of blacks is more akin to that of a Ford Pinto; for he undoubtedly took blacks to be perpetual children. Chilren are persons, too; however, no one has ever supposed that moral theory applies to children in the full way that it applies to adults. (shrink)

In this paper I will develop the argument that a cognitivist and virtue ethical approach to moral reasons is the only approach that can sustain a non-alienated relation to one’s character and ethical commitments. [Thomas, 2005] As a corollary of this claim, I will argue that moral reasons must be understood as reasonably partial. A view of this kind can, nevertheless, recognise the existence of general and positive obligations to humanity. Doing so does not undermine the view by leading (...) to a highly demanding view of morality. Indeed, it offers a defence against the view that an analogy between obligations of immediate rescue to particular individuals and general and positive obligations to humanity leads to the conclusion that morality is highly demanding. The plan of this paper is as follows. The first section sets out the main elements of a cognitivist and virtue ethical approach to moral reasons. The second applies it to the test case of an argument that claims that one way in which one seeks to lead a non-alienated ethical life, a life of integrity, is incompatible with the requirements of consequentialism given certain very general facts about the moral state of the world.

There are few ideas as important to the history of modern democracy as that of the nation as a political community. And yet, by comparison to its companion idea of political community as based upon the agreement of free and equal individuals, it remained until recently a marginal concern of liberal political theory. The aftermath of decolonization and the breakup of the Soviet empire, among other things, has changed that and brought it finally to the center of theoretical attention. And (...) once there, the deep-seated tensions in theory between nationalism and liberalism have proved to be as hard to overlook as their all too familiar tensions in practice. (shrink)

Since the validity of Bell's inequalities implies the existence of joint probabilities for non-commuting observables, there is no universal consensus as to what the violation of these inequalities signifies. While the majority view is that the violation teaches us an important lesson about the possibility of explanations, if not about metaphysical issues, there is also a minimalist position claiming that the violation is to be expected from simple facts about probability theory. This minimalist position is backed by theorems due to (...) A. Fine and I. Pitowsky.Our paper shows that the minimalist position cannot be sustained. To this end,we give a formally rigorous interpretation of joint probabilities in thecombined modal and spatiotemporal framework of `stochastic outcomes inbranching space-time' (SOBST) (Kowalski and Placek, 1999; Placek, 2000). We show in this framework that the claim that there can be no joint probabilities fornon-commuting observables is incorrect. The lesson from Fine's theorem is notthat Bell's inequalities will be violated anyhow, but that an adequate modelfor the Bell/Aspect experiment must not define global joint probabilities. Thus we investigate the class of stochastic hidden variable models, whichprima facie do not define such joint probabilities. The reasonwhy these models fail supports the majority view: Bell's inequalities are notjust a mathematical artifact. (shrink)

Interpretations of Heidegger often fail to distinguish between two very different matters -- on the one hand “the turn” (die Kehre), and on the other hand “the change in Heidegger’s thinking” (die Wendung im Denken), that is, the shift in the way Heidegger formulated and presented his philosophy beginning in the 1930s. Failure to make this distinction can be disastrous for understanding Heidegger, and the danger becomes more acute the closer one gets to texts like Introduction to Metaphysics, where both (...) the “turn” and the “change” begin to come into their own.1..

Keith DeRose gives an invalid argument for contextualism in “Assertion, Knowledge, and Context.” In section 2.4, entitled “The Argument for Contextualism,” DeRose makes the following remarks. “The knowledge account of assertion provides a powerful argument for contextualism: If the standards for when one is in a position to warrantedly assert that P are the same as those that comprise a truth-condition for ‘I know P,’ then if the former vary with context, so do the latter. In short: The knowledge account (...) of assertion together with the context-sensitivity of assertability yields contextualism about knowledge”. (shrink)

Aristotle's treatment of logos apophantikos is found within the treatise that bears the title Peri Hermeneias, On Hermeneia. And it was to this treatise -- or, more accurately, to the first four sections of it -- that the early Heidegger turned again and again in his courses during the 1920s in an effort to retrieve from this phenomenon a hidden meaning.

In the framework of set theory we cannot distinguish between natural and non-natural predicates. To avoid this shortcoming one can use mathematical structures as conceptual spaces such that natural predicates are characterized as structurally nice subsets. In this paper topological and related structures are used for this purpose. We shall discuss several examples taken from conceptual spaces of quantum mechanics (orthoframes), and the geometric logic of refutative and affirmable assertions. In particular we deal with the problem of structurally distinguishing between (...) natural colour predicates and Goodmanian predicates like grue and bleen. Moreover the problem of characterizing natural predicates is reformulated in such a way that its connection with the classical problem of geometric conventionalism becomes manifest. This can be used to shed some new light on Goodman's remarks on the relative entrenchment of predicates as a criterion of projectibility. (shrink)

Determining whether US companies and some of the persons involved in them are acting ethically when conducting the research described in the Havrix Case and the Surfaxin Trial requires reflection on the moral objections that could be raised against what they did. Given the wide range of possible moral objections, it would be folly to try to display and discuss them all in the space of this essay. I concentrate then on a kind of moral objections that strike me as (...) especially interesting, plausible, and important. I try to work out whether such objections are valid and, if so, what significance they have for the conduct of the pharmaceutical companies in question — and for the conduct of ourselves as citizens of democratic countries under whose jurisdiction these companies operate.

The Kantian account of political authority holds that the state is a necessary and sufficient condition of our freedom. We cannot be free outside the state, Kantians argue, because any attempt to have the ‘acquired rights’ necessary for our freedom implicates us in objectionable relations of dependence on private judgment. Only in the state can this problem be overcome. But it is not clear how mere institutions could make the necessary difference, and contemporary Kantians have not offered compelling explanations. I (...) present a detailed analysis of the problems Kantians identify with the state of nature and the objections they face in claiming that the state overcomes them. I then sketch a response on behalf of Kantians. The key idea is that only under state institutions can a person can make claims of acquired right without presupposing that she is by nature exceptional in her capacity to bind others. (shrink)

(1) the distributive effects of past wrongs: One or more individual or collective agents — “the perpetrators” — acted wrongly at t0, effecting a continuing change in the distribution of status or assets at t1. It may follow that some agents at t1 have moral reason to alter this distribution of status or assets at t1, presumably with an eye to mitigating the distributive effects that the wrongdoing at t0 will have had from t1 on.

Two problems continue to haunt Heideggerian scholarship and to pose needless obstacles to those who seek to enter his thought. One is the almost ritualistic repetition of the master’s terminology—especially at its most manneristic—on the part of his disciples. Another is the tendency, which is found in Heidegger as well as in his disciples, to hypostasize “being” into an autonomous “other” that seems to function on its own apart from entities and from man. Both of these problems gather around Heidegger’s (...) key word Ereignis and therefore around his interpretation of the history of philosophy, and they obscure a clear insight into what he was trying to say.

Thomas C. Vinci argues that Kant's Deductions demonstrate Kant's idealist doctrines and have the structure of an inference to the best explanation for correlated domains. With the Deduction of the Categories the correlated domains are intellectual conditions and non-geometrical laws of the empirical world. With the Deduction of the Concepts of Space, the correlated domains are the geometry of pure objects of intuition and the geometry of empirical objects.
