Familial clustering of a disease is defined as the occurrence of the disease within some families in excess of what would be expected from the occurrence in the population. It has been demonstrated for several cancer types, ranging from rare cancers as the adenomatosis-coli-associated colon cancer or the Li-Fraumeni syndrome to more common cancers as breast cancer and colon cancer. Familial clustering, however, is merely an epidemiological pattern, and it does not tell whether genetic or environmental causes or both in (...) combination are responsible for the familial clustering. Familial clustering may be due to genetic predisposition to the disease, but exposure to environmental factors — shared by members of some families, but not by members of other families — may also cause familial clustering and hence mimic genetic inheritance in the study of nuclear families. Based on assumptions regarding the individual steps in the biological process starting with exposure to carcinogens and ending with death from disseminated cancer we suggest that genetic and environmental factors may both be involved in most of these steps. The present paper focuses on research methodologies necessary to discriminate between the effect of genes and family environment in the development of cancer. (shrink)

Animal use in medical research is widely accepted on the basis that it may help to save human lives and improve their quality of life. Recently, however, objections have been made specifically to the use of animals in scientific investigation of human obesity. This paper discusses two arguments for the view that this form of animal use, unlike some other forms of animal-based medical research, cannot be defended. The first argument leans heavily on the notion that people themselves are responsible (...) for developing obesity and so-called ‘lifestyle’ diseases; the second involves the claim that animal studies of obesity's causes and therapies distract attention from preventive efforts. Drawing on both empirical data and moral reasoning, we argue that the relevant attributions of responsibility and claims about distraction are not plausible, and that, therefore, there is no reason to single out the use of animals in obesity research as especially problematic.

THE PURPOSE OF THIS ARTICLE IS TO SHOW HOW HUME’S SCEPTICISM ABOUT MIRACLES GENERATES "EPISTEMOLOGICAL" SCEPTICISM ABOUT TIME TRAVEL. SO THE PRIMARY QUESTION RAISED HERE IS "CAN ONE KNOW THAT TIME TRAVEL HAS OCCURED?" RATHER THAN "CAN TIME TRAVEL OCCUR?" I ARGUE THAT ATTEMPTS TO SHOW THE EXISTENCE OF TIME TRAVEL WOULD FACE THE SAME METHODOLOGICAL PROBLEMS AS THE ONES CONFRONTING ATTEMPTS TO DEMONSTRATE THE EXISTENCE OF PARANORMAL EVENTS. SINCE HUMEAN SCEPTICISM EXTENDS TO THE STUDY OF PARANORMAL EVENTS (PARAPSYCHOLOGY), HUMEANS (...) ARE COMMITTED TO SCEPTICISM ABOUT THE STUDY OF TIME TRAVEL ("PARAHISTORY"). (shrink)

Drawing inspiration from the ethical pluralism of G. E. Moore's Principia Ethica, I contend that one empty world can be morally better than another. By ?empty? I mean that it is devoid of concrete entities (things that have a position in space or time). These worlds have no thickets or thimbles, no thinkers, no thoughts. Infinitely many of these worlds have laws of nature, abstract entities, and perhaps, space and time. These non-concrete differences are enough to make some of them (...) better than others. 1I thank Walter Sinnott-Armstrong, John Carroll, and Gideon Rosen for their comments and suggestions.

The aim of this paper is to show how thought experiments help us learn about laws. After providing examples of this kind of nomic illumination in the first section, I canvass explanations of our modal knowledge and opt for an evolutionary account. The basic application is that the laws of nature have led us to develop rough and ready intuitions of physical possibility which are then exploited by thought experimenters to reveal some of the very laws responsible for those intuitions. (...) The good news is that natural selection ensures a degree of reliability for the intuitions. The bad news is that the evolutionary account seems to limit the range of reliable thought experiment to highly practical and concrete contexts. In the fifth section, I provide reasons for thinking that we are not as slavishly limited as a pessimistic construal of natural selection suggests. Nevertheless, I promote the idea that biology is a promising source of predictions and diagnoses of thought experiment failures. (shrink)

This is a defense and extension of Stephen Yablo's claim that self-reference is completely inessential to the liar paradox. An infinite sequence of sentences of the form 'None of these subsequent sentences are true' generates the same instability in assigning truth values. I argue Yablo's technique of substituting infinity for self-reference applies to all so-called 'self-referential' paradoxes. A representative sample is provided which includes counterparts of the preface paradox, Pseudo-Scotus's validity paradox, the Knower, and other enigmas of the genre. I (...) rebut objections that Yablo's paradox is not a genuine liar by constructing a sequence of liars that blend into Yablo's paradox. I rebut objections that Yablo's liar has hidden self-reference with a distinction between attributive and referential self-reference and appeals to Gregory Chaitin's algorithmic information theory. The paper concludes with comments on the mystique of self-reference. (shrink)

About twenty years ago, philosophers debated the verifiability of the statement “Last night everything doubled in size.” It seems that universal nocturnal expansion would double our rulers and tape measures making the size change indiscernible. I think that there is an internal analogue to the question “Did everything double in size last night?” The question “Did my preferences double in intensity last night?“ also raises problems of verification.

I can get away with it because no one is in a position to call me on it. Professor Robinson cannot consistently complain that (A) begs the question against his thesis that there is no such fallacy. He would discourage anyone from "helping" him by accusing me of committing the fallacy against him. With advocates like that, who needs adversaries? I. EMBEDDING PERSPECTIVES After all, Robinson has a viable reply to my argument. He should simply deny my premise. Later I (...) will show how (A) might rationally persuade Robinson. But my immediate goal is not to convert the skeptic about the existence of the fallacy but rather to use his extreme position to make a point about the nature of question-begging. Those who object that argument (A) begs the question against Robinson must do so on behalf of Robinson. This assistance requires that one launch the accusation from Robinson's perspective and with his dialectical interests at heart. (shrink)

Peter Slezak and William Boos have independently advanced a novel interpretation of Descartes's "cogito". The interpretation portrays the "cogito" as a diagonal deduction and emphasizes its resemblance to Godel's theorem and the Liar. I object that this approach is flawed by the fact that it assigns 'Buridan sentences' a legitimate role in Descartes's philosophy. The paradoxical nature of these sentences would have the peculiar result of undermining Descartes's "cogito" while enabling him to "disprove" God's existence.

This paper is devoted to a solution to Moore's problem. After explaining what Moore's problem is and after considering the main approaches toward solving the problem, I provide a definition of Moorean sentences in terms of pure Moorean propositions. My solution to Moore's problem essentially involves a description of how one can contradict oneself without uttering a contradiction, and a set of definitions that exactly determines which sentences are Moorean and which are close relatives of Moorean sentences.

An electoral evaluation of a set of expert opinions proceeds by treating the experts as voters. Although this method allows us to formalise our naive views about how to take expert advice, the formalisations are plagued by paradoxes which parallel those found in literature on social aggregation devices. This parallel suggests that our naive views about taking expert advice are in as much need of revision as our naive views about deriving group preferences from individual preferences. * I am indebted (...) to Joseph Hanna for a number of criticisms and corrections to a previous draft.

Epistemologists have profited from studies of the ways in which ‘know’ is ambiguous. We can also profit by studying the ways in which ‘know’ is vague. After classifying sources of vagueness for ‘know,’ I spend the second section examining theories of vagueness. With the exception of the theory that vague predicates are incoherent, which I try to refute, we need not take a stand on a particular theory to show that the vagueness of knowledge has substantive epistemological implications. The third (...) section supports the thesis through a survey of ways in which appeals to vagueness can be applied to the field's issues. First, I show how higher order vagueness is evidence against the KK thesis, the incorrigibility of sense data, and the completability of epistemology. An interesting resemblance between infinity and vagueness provides the point of departure for the next type of application. For this resemblance suggests a new way of handling apparently infinite belief structures. The approach is illustrated with an analysis of common knowledge. The third type of application concerns the ways in which disguised sorites creep into our thinking about knowledge. In addition to brief illustrations concerning naive holism, question begging, and an objection to incorrigibilism, I provide more detailed illustrations involving Jonathan Adler's sceptical appeal to epistemic universalizability, the prediction paradox, and William Lycan's objection to Gilbert Harman's social knowledge cases. I conclude with some general remarks on the lessons to be learned from the vagueness of knowledge. (shrink)

If a spinning sphere casts a shadow, does the shadow also spin? This riddle is the point of departure for an investigation into the nature of shadow movement. A general theory of motion will encompass all moving things, not just physical objects. Ultimately, I argue that round shadows do indeed spin. Shadows are followers of the objects that cast them. Parts of the shadow correspond to parts of the leader, so motion of the caster's parts accounts for motions of the (...) shadow's parts. I conclude with a discussion of how the dynamic aspects of shadows impose subtle constraints on other puzzles about shadows. (shrink)

The Pyrrhonian sceptic Favorinus of Arelata personified indeterminacy, cultivating his (or her) borderline status to undermine dogmatism. Inspired by the techniques of Favorinus, I show, by example, that ‘vague’ has borderline cases. These concrete steps lead to a more abstract argument that ‘vague’ has borderline borderline cases and borderline borderline borderline cases. My specimens are intended supplement earlier non-constructive proofs of the vagueness of ‘vague’.

What is the relevance to praiseworthiness and blameworthiness of what one would have done in other, counterfactual circumstances? I defend a moderate form of actualism: what one would have done is important, but less so than what one actually does.

To understand death, you need to compare mortality with immortality. I am here to help. In addition to my personal testimony, I present highlights from a survey of immortal species and a survey of infinitistic varieties of mortality. These field studies rebut Fredrich Nietzsche’s thesis that immortality is inevitably repetitious, Bernard Williams’ allegation that immortality is inevitably boring, and Epicurus’ thesis that death cannot be bad for you. On the positive side, the study shows that the main difference between immortality (...) and mortality are quantitative. Attention is also given to some striking qualitative differences. (shrink)

Surprisingly, the fact that the speaker is lying is sometimes common knowledge between everyone involved. Strangely, we condemn these bald-faced lies more severely than disguised lies. The wrongness of lying springs from the intent to deceive – just the feature missing in the case of bald-faced lies. These puzzling lies arise systematically when assertions are forced. Intellectual duress helps to explain another type of non-deceptive false assertion : lying to yourself. In the end, I conclude that the apparent intensity of (...) our disapproval of non-deceptive lies is a rhetorical illusion. (shrink)

The principle of charity says that all agents are rational. The principle of meta‐charity says that all agents believe all agents are rational. My thesis is that the arguments which are used to support charity also support meta‐charity. Meta‐charity implies meta‐meta‐charity. By recursion, the principle of charity implies that it is common knowledge. But there appears to be intelligent, well‐informed disagreement with the principle of charity. So if the entailment thesis holds, opponents of the principle of charity have a new (...) objection to the principle. Defenders of the principle of charity must either refute the entailment thesis or accept much stronger consequences than they expected.“As I am, so I see.”—Ralph Waldo Emerson. (shrink)

An ill-informed reading of Adam Ferguson 's epitaph has given me an idea for securing posthumous recognition. Consider philosophers in the year 2201 who read my epitaph: ‘Here lies Roy Sorensen who will be long remembered for his paradoxes’. If these future scholars remember me, then well and good. If they do not remember me, my epitaph will appear to be rendered false by their failure to recall me. Suppose the poignancy of this self-defeat leads my epitaph to be widely (...) repeated. I thereby acquire ignominy as the forgotten philosopher. But wait! Eventually someone will notice that no one can remember that Roy Sorensen is forgotten. For if someone did remember that Roy Sorensen is forgotten, then he would be forgotten—not remembered. After all, memory implies truth. Thus the self-defeating aspect of my epitaph is itself self-defeating! The happy ending is that my epitaph becomes a self-fulfilling prophesy by a curious kind of double-negation. (shrink)

Commanders gain authority from obedience and lose authority from disobedience. We should expect commanders to therefore devise commands that reduce the probability of disobedience. To aid recognition of these techniques for reducing the risk of disobedience, I focus on the extreme of case of commands that reduce the probability to zero. Each of my ten commandments illustrates a logical technique for engineering out disobedience. Once you master these safety measures, you can confidently legislate your own universal maxims. Your innovations will (...) be good news for Immanuel Kant’s characterization of morality in terms of categorical imperatives. The commandments also raise interesting questions about responsibility for necessities and the nature of rule following. (shrink)

If there is to be any progress in the debate about what sort of positive moral status Kant can give the emotions, we need a taxonomy of the terms Kant uses for these concepts. It used to be thought that Kant had little room for emotions in his ethics. In the past three decades, Marcia Baron, Paul Guyer, Barbara Herman, Nancy Sherman, Allen Wood and others have argued otherwise. Contrary to what a cursory reading of the Groundwork may indicate, Kant (...) thinks the emotions play an important role in the moral life. I want to extend the work of Baron, Guyer, Herman, Sherman and Wood in three ways. First, I will set out in a diagram Kant's taxonomy of feelings and emotions. Agreement on such a taxonomy should make it easier to evaluate debates about Kant and the emotions. Second, I will focus on a certain subclass of emotions – reason-caused affects – that have previously received little attention, even from these Kant scholars. Third, these scholars base much of their defence of Kant on his later works – especially the Metaphysics of Morals and the Anthropology – but Kant's fairly rich taxonomy of the emotions, including reason-caused affects, is clearly in place at least as early as the Critique of Judgment . I believe that the Critique of Judgment is an importantly ignored resource for understanding the moral role of the emotions for Kant. The third Critique makes positive, philosophically interesting claims about the emotions and morality. Kant emphasizes certain roles for emotions in this work that he develops to the same extent nowhere else. Nevertheless, the Critique of Judgment goes all but unmentioned by many who write on these issues. In what follows, I will defend as many of my claims as possible using the third Critique. (shrink)

In ‘Epistemic Modals’ (2007), Seth Yalcin proposes Stalnaker-style semantics for epistemic possibility. He is inspired by John MacFarlane’s ingenious defence of relativism, in which claims of epistemic possibility are made rigidly from the perspective of the assessor’s actual stock of information (rather than from the speaker’s knowledge base or that of his audience or community). The innovations of MacFarlane and Yalcin independently reinforce the modal collapse espoused by Jaakko Hintikka in his 1962 epistemic logic (which relied on the implausible KK (...) principle and heavy idealizations). I respond to this new challenge with fresh objections to the underlying S4 equivalence: p p . I also propose counter-analyses of the intriguing data which Yalcin cites in support of his new semantics. A key collateral motivation for this defence of irredundant iterations is to ward off a threat to higher order vagueness. (shrink)

Do we need light to see? I argue that the black experience of a man in a perfectly dark cave is a representation of an absence of light, not an absence of representation. There is certainly a difference between his perceptual knowledge and that of his blind companion. Only the sighted man can tell whether the cave is dark just by looking. But perhaps he is merely inferring darkness from his failure to see. To get an unambiguous answer, I switch (...) the focus from perceptual knowledge to non-epistemic seeing. My conclusion is that we see even in the limiting case of absolute darkness - regardless of whether we believe we are seeing. We see little of pratical interest. But in terms of basic information, we see about as much as we do when the lights are on. Depending on what has gone before and after, we may even see ordinary objects. (shrink)

Immanuel Kant promised, ‘as Your Majesty's loyal subject’, to abstain from all public lectures about religion. All past commentators agree this phrase permitted Kant to return to the topic after the King died. But it is not part of the ‘at-issue content’.

Just as the guarantee stands regardless of whether the (...) guarantor ceases to be your devoted fan, the compliance conditions of Kant's promise are not affected by Kant's ceasing to be the king's loyal subject. For good or ill, Kant made a lying promise to King Friedrich Wilhelm II in 1794. (shrink)

Some say moral bioenhancements are urgent and necessary; others say they are misguided or simply will not work. I examine a class of arguments claiming that moral bioenhancements are problematic because they are self-subverting. On this view, trying to make oneself or others more moral, at least through certain means, can itself be immoral, or at least worse than the alternatives. The thought here is that moral enhancements might fail not for biological reasons, but for specifically morally self-referential reasons. I (...) argue that moral bioenhancements, in a restricted set of cases, are self-subverting such that they are impermissible. Further, some moral bioenhancements would result in agents who are less admirable than they might have been through other means. (shrink)

Lake Tanganiyka has lefty and righty cichlid fish that show there can be natural selection for a trait over its mirror image counterpart.This raises the question Can there be biological selection of a whole organism over its mirror image counterpart?

I present Flatlander thought experiment to demonstrate that mirror imagecounterparts are duplicates because they only differ in how they (...) happen to be oriented in space. The counterparts have the same intrinsic properties and are in the same environment,so there can be no difference in fitness. (shrink)

If you read this abstract, then you will understand what my essay is about. Under what conditions would the preceding assertion be a lie? Traditional definitions of lying are always applied to straight declaratives such as ‘The dog ate my homework’. This one sided diet of examples leaves us unprepared for sentences in which conditional probability governs assertibility. The truth-value of conditionals does not play a significant role in the sincere assertion of conditionals. Lying is insincere assertion. So the connection (...) between lying and falsehood is broken when lying with conditionals. Drawing on Frank Jackson's account of indicative conditionals. I argue that it is possible to lie with true conditionals by virtue of their false conventional implicatures. False conversational implicatures only guarantee misleading assertions, not lies. Lying remains a semantic rather than a pragmatic affair. (shrink)

A blindspot is a consistent but inaccessible proposition. For instance, I cannot know 'The test is on Friday but I do not know it'. No contradiction follows from the supposition that you know my blindspot. But could you know my blindspot if we are epistemic peers? Epistemic peers have the same evidence and reasoning ability. So either both peers know a proposition or both are ignorant. Since I cannot know my blindspot, neither can my peer. Thus the formal ignorance associated (...) with blindspots spreads to my peers. This contagion is used to improve a solution to the blindspot solution to the surprise test paradox. (shrink)

A para-reflection is a privational phenomenon that is often mistaken for a reflection. You have seen them as the ‘reflection’ of your pupil in the mirror. Your iris reflects light in the standard way but your pupil absorbs all but a negligible amount of light (as do other dark things such as coal and black velvet). Para-reflections work by contrast.

Evans-Pritchard’s witchcraft inheritance argument is a sorites argument—albeit in a form masked by the different ontologies of the Azande and Evans-Pritchard.

Justifying judicial review as a democratic institution is a core concern of Cristina Lafont’s splendid new book. Even though her interpretation is appealing, this also poses some problems. This is due to the non-thematization of ideology that results from Lafont’s ideal-theoretical and argument-privileging approach. I will first address this ideology-problem and then reflect on the implications that this has for the question of what is considered legitimate political action.

One of the factors that contributes to an agent’s praiseworthiness and blameworthiness - his or her moral worth – is effort. On the one hand, agents who act effortlessly seem to have high moral worth. On the other hand, agents who act effortfully seem to have high moral worth as well. I explain this pair of intuitions and explore the contour of our views about cases in between them. This paper uses conceptual graphs for clarity and, in additional work I (...) have done on value theory, as arguments. Conceptual graphs reflect a way of doing philosophy that is new and powerful, as reflected in work over the past several decades by Derek Parfit, Shelly Kagan, Larry Temkin, and Thomas Hurka.

Next SectionSome argue that genetic enhancements and environmental enhancements are not importantly different: environmental enhancements such as private schools and chess lessons are simply the old-school way to have a designer baby. I argue that there is an important distinction between the two practices—a distinction that makes state restrictions on genetic enhancements more justifiable than state restrictions on environmental enhancements. The difference is that parents have no settled expectations about genetic enhancements.

This article considers question‐begging's opposite fallacy. Instead of relying on my beliefs for my premises when I should be using my adversary's beliefs, I rely on my adversary's beliefs when I should rely on my own. Just as question‐begging emerges from egocentrism, its opposite emerges from other‐centrism. Stepping into the other person's shoes is an effective strategy for understanding him. But you must return to your own shoes when forming your beliefs. Evidence is agent centered. Other‐centric reasoning is most striking (...) when both parties partake simultaneously. We are then treated to the spectacle of each side using the other's premises to establish its conclusion. These remarkable debates arise regularly when there is open disagreement about whether a right‐conferring relationship has ended. Those who contend the relationship is abrogated will be tempted to stand on the rights persistently credited to them by their adversary. (shrink)

This article attempts to explore some current theoretical problems within the field of postcolonial studies. In particular, I address Ato Quayson's recent complaint that postcolonial theorists generally have failed to ‘provide a persuasive account of literature and history simultaneously’, a problem which I link to what I see as the field's theoretical obsession with the concept of ‘representation’; I argue that the field's disciplinary ambition to represent, authoritatively, the postcolonial per se necessarily but also problematically circumscribes and limits its relation (...) to discourses of historical representation and literary representation. On an aesthetic level, this problematic is expressed through postcolonial studies’ troubled relationship with literary realism as an aesthetic form. In a wider perspective, I connect the field's disparagement of literary realism with Lazarus's notion of the ‘postcolonial unconscious’, i.e. postcolonial studies’ failure to grasp and address some of the deeper global-political contradictions.

Actions are right or wrong; agents are good or bad. Most ethicists are interested in the first dimension. My work is about the second. Factors relevant to the first dimension include, for example, the action's consequences and whether the action is a harm. But many other morally compelling factors are neglected if we focus exclusively on right and wrong---factors such as motives, intentions, effort, and character. These are among the factors of a second dimension, moral worth: the goodness or badness (...) of agents. We can perform right actions without being good agents. Knowing which actions are right only partially helps us answer the question of what it is to be good. ;I take it that what I have just said reflects ordinary moral intuitions. Nevertheless moral worth is a neglected topic in contemporary philosophical ethics. Others have written about specific virtues, or about "virtue ethics" as an alternative moral theory to consequentialism and deontology. But I know of no one else who has attempted a close analysis of the general factors that constitute praiseworthiness and blameworthiness. An account of these factors is relevant to any of the three leading contemporary ethical theories. ;My examination of these factors yields a surprising wealth of possible positions. I map out these positions and argue for the best of them. My specific topics include the nature of motives, Kantian views about the motive of duty, the relative weight of first-order and second-order motives, patterns of motives, effort as a complex of apparently conflicting subfactors, and the relevance of counterfactual circumstances to character. I appeal to the cases of Oskar Schindler and Huck Finn, among others, to illustrate the complexities of these issues. ;My dissertation is the first systematic analysis of the factors of moral worth. Internal states of persons---motives, intentions, effort, character---matter to us, and an ethical theory is richer with an adequate account of them. (shrink)

Can merely thinking about an imaginary situation provide evidence for how the world actually is--or how it ought to be? In this lively book, Roy A. Sorensen addresses this question with an analysis of a wide variety of thought experiments ranging from aesthetics to zoology. Presenting the first general theory of thought experiment, he sets it within an evolutionary framework and integrates recent advances in experimental psychology and the history of science, with special emphasis on Ernst Mach and Thomas Kuhn. (...) Sorensen explores what thought experiments are, how they work, and what their virtues and vices are. In his 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. Sorensen assesses the hazards of thought experiments and grants that there are interesting ways in which the method leads us astray, but attacks most scepticism about thought experiments as arbitrary. He maintains that they should be used--as they generally are--as part of a diversified portfolio of techniques, creating a network of cross-checks that make for impressive reliability. (shrink)
