Insanity is identified with irrationality, while rationality is considered to be the mark of sanity. Yet we want to say that rationality could be the cause of insanity. We can see a subtle kind of insanity inherent in an institution believed to be highly rational. Rationality in an ideological belief also turns into rational insanity when the ideology itself works for the interest of the advantaged as a tool of deception. We believe in the rationality of open communication. We believe (...) that information technology has given us the most rational means for open communication. The Internet revolution or Internet democracy is expected to become the most rational means for the institutional goal of democracy. However the rationality of Internet communication has demonstrated a serious tendency to cause Internet insanity. We have been proud of being 'rational animals'. But now we are concerned because 'rational animal' could mean 'rational but animal-like' or 'rational but impulsive', which in turn could mean 'rational but violent' or 'rational but mad and insane'. Perhaps it is time for us to think seriously about the possibility of mass insanity through rational insanity, and seek the way beyond such rational insanity. (shrink)
Hawking, in his book, A Brief History of Time, concludes with a conditional remark: If we find a complete theory to explain the physical world, then we will come to understand God’s mind. With Goedel in mind, we can raise questions about the completeness of our scientific understanding and the nature of our understanding with regard to God’s mind. We need to ask about the higher order of our understanding when we move to knowing God’s mind. We go onto develop (...) these problems with Nietzsche’s thoughts on the death of God, and the emergence of super human intelligences. Then, we come to Buddha, a logical genius, to see how the Buddhistic enlightenment exemplifies the super human intelligence, as well as the higher order understanding in our knowledge of God’s mind.

In scientific explanations, the explanans theory is sometimes incommensurable with the explanandum empirical data. How is this possible, especially when the explanation is deductive in nature? This paper attempts to solve the puzzle without relying on any particular theory of reference. For us, it is rather obvious that the geometric idea of projection plays a key role in Keplers explanation of Tycho Brahes empirical data. We discover that a similar mechanism operates in theoretic explanations in general. In short, all theoretic (...) explanations are projective explanations. If so, there should be no logical reason why explanans theories cannot be incommensurable with explanandum data. For illustration, we analyse Einsteins explanation of the results of the Michelson–Morley experiment in some detail. (shrink)
This paper investigates the relationship between ethics and income among individuals of different religions in the HKSAR of China. The presence of both traditional Chinese religion and Christianity from the West makes our study particularly interesting. The content of ethical beliefs varies with religion and thus the effect of ethics on income may also vary across religion. Furthermore, a reverse causal relationship may run from income to ethics. Since culture and taste affect the consumption behavior of a person, depending on (...) the religion of the person, a person with a higher income may or may not like to ‘acquire’ more ethics. Our empirical results find that there is indeed a simultaneous relationship between income and being ethical so that a single equation estimation of income on ethics and vice versa generates biased estimates. Using a two-stage instrumental variable estimation, our study finds that being ethical contributes to higher income for Christians and the non-religious group, but lowers it for people of traditional Chinese religion. On the other hand, an increase in income increases the likelihood of a person’s being ethical for both Christians and the people of traditional Chinese religion, but reduces it for the non-religious group.

Cultural pluralism has caused disturbing problems for philosophers in applied ethics. If moral sanctions, theories, and applications are culturally bound, then moral conflicts ensuing from cultural differences would seem to be irresolvable. Even human nature, good or evil, is not free from cultural determination. One way out of this pluralistic impasse is the expansion of the moral mind. It is the outlet taken by religion, the arts, and philosophy from the earliest time in human culture. In philosophy we find an (...) authentic example of this in Socrates. Following the practice of Socrates, we can try to expand the moral mind philosophically, that is, by working on various forms of reasoning, both deductive and non-deductive, including induction, abduction, dialectics, analogy, and pragmatics.

In my book How the Mind Works, I defended the theory that the human mind is a naturally selected system of organs of computation. Jerry Fodor claims that 'the mind doesn't work that way'(in a book with that title) because (1) Turing Machines cannot duplicate humans' ability to perform abduction (inference to the best explanation); (2) though a massively modular system could succeed at abduction, such a system is implausible on other grounds; and (3) evolution adds nothing to our understanding (...) of the mind. In this review I show that these arguments are flawed. First, my claim that the mind is a computational system is different from the claim Fodor attacks (that the mind has the architecture of a Turing Machine); therefore the practical limitations of Turing Machines are irrelevant. Second, Fodor identifies abduction with the cumulative accomplishments of the scientific community over millennia. This is very different from the accomplishments of human common sense, so the supposed gap between human cognition and computational models may be illusory. Third, my claim about biological specialization, as seen in organ systems, is distinct from Fodor's own notion of encapsulated modules, so the limitations of the latter are irrelevant. Fourth, Fodor's arguments dismissing of the relevance of evolution to psychology are unsound. (shrink)
Objections to AI and computational cognitive science are myriad. Accordingly, there are many different reasons for these attacks. But all of them come down to one simple observation: humans seem a lot smarter that computers -- not just smarter as in Einstein was smarter than I, or I am smarter than a chimpanzee, but more like I am smarter than a pencil sharpener. To many, computation seems like the wrong paradigm for studying the mind. (Actually, I think there are deeper (...) and darker reasons why AI, especially, is so often the brunt of polemics, see Dietrich, 2000.) But the truth is this: AI is making exciting progress, and will one day make a robot as intelligent as a person; indeed the robot will be conscious. And all this is because of another truth: the computational paradigm is the best thing to come down the pike since the wheel. (shrink)
Frank Jackson's knowledge argument against physicalism has caused an extensive debate. In this paper, I sketch and examine a new argument against Jackson's view, an argument which appears to retain more of physicalism than other replies to Jackson. this argument draws strength from a causal theory of knowledge, and hold that there is no knowledge of epiphenomenal qualia, hence that Jackson's main conclusions from the thought experiment are incorrect. There are still problems with this argument, however, so the question remains (...) how much of the mental that can be accounted for in physicalist terms. (shrink)
Peter van Inwagen notes: "... almost all philosophers agree that a necessary condition for holding an agent responsible for an act is believing that the agent could have refrained from performing that act." Perhaps van Inwagen is right; perhaps most philosophers agree on this. If so, this shared assumption, which I will call CDO (for "could have done otherwise"), is a good candidate for denial, especially since there turns out to be so little to be said in support of it, (...) once it is called in question. I will argue that, just like those people who are famous only for being famous, this assumption owes its traditional high regard to nothing more than its traditional high regard. It is almost never questioned. And the tradition itself, I will claim, is initially motivated by little more than inattentive extrapolation from familiar cases. To engage the issue, I assert that it simply does not matter at all to moral responsibility whether the agent in question could have done otherwise in the circumstances. (shrink)
A "moral hazard" is a market failure most commonly associated with insurance, but also associated by extension with a wide variety of public policy scenarios, from environmental disaster relief, to corporate bailouts, to natural resource policy, to health insurance. Specifically, the term "moral hazard" describes the danger that, in the face of insurance, an agent will increase her exposure to risk. If not immediately clear, such terminology invokes a moral notion, suggesting that changing one's exposure to risk after becoming insured (...) is morally problematic. This paper challenges that position. It argues that there is nothing inherently moral about the moral hazard. It does so by arguing against three proposed claims regarding the wrongness of the moral hazard: first, the view that conceives of it as deception; then, the view that conceives of it as cheating; and finally, the view that conceives of it as stealing.

"Consciousness" is a multiply ambiguous word, and if our goal is to explain perceptual consciousness we had better be clear about which of the many senses of the word we are endorsing when we sign on to the project. I describe some of the relatively standard distinctions made in the philosophical literature about different meanings of the word "conscious". Then I consider some of the arguments of David Chalmers and of Ned Block that states of "phenomenal consciousness" pose special and (...) intractable problems for the scientific understanding of perception. I argue that many of these problems are introduced by obscurities in the term itself, and propose a distinction between epistemic and non-epistemic senses of the term "phenomenal consciousness". That distinction helps explain why phenomenal consciousness seems so mysterious to so many people. States of "phenomenal consciousness" are not states of one, elemental (and inexplicable) kind; they are a ragtag lot, of differing levels of complexity, corralled under one heading by a regrettable ambiguity in our terminology.

Jacques Mehler was notoriously charitable in embracing a diversity of approaches to science and to the use of many different methodologies. One place where his ecumenism brought the two of us into disagreement is when the evidence of brain imaging was cited in support of different psychological doctrines, such as the picture-theory of mental imagery. Jacques remained steadfast in his faith in the ability of neuroscience data (where the main source of evidence has been from clinical neurology and neuro-imaging) to (...) choose among different psychological positions. I personally have seen little reason for this optimism so Jacques and I frequently found ourselves disagreeing on this issue, though I should add that we rarely disagreed on substantive issues on which we both had views. This particular bone of contention, however, kept us busy at parties and during the many commutes between New York and New Jersey, where Jacques was a frequent visitor at the Rutgers Center for Cognitive Science. Now that I am in a position where he is a captive audience it seems an opportune time to raise the question again. (shrink)
Evolutionary psychology is a science in the making, working toward the goal of showing how psychological adaptation underlies much human behavior. The knee-jerk reaction that sociobiology is unscientific because it tells just-so stories has become a common charge against evolutionary psychology as well. My main positive thesis is that inference to the best explanation is a proper method for evolutionary analyses, and it supplies a new perspective on the issues raised in Schlinger's (1996) just-so story critique. My main negative thesis (...) is that, like many nonevolutionist critics, Schlinger's objections arise from misunderstandings of the evolutionary approach.Evolutionary psychology has progressed beyond telling just-so stories. It has found a host of ingenious special techniques to test hypotheses about the adaptive significance and proximate mechanisms of behavior. Naturalistic data using the comparative method combined with controlled tests using statistical analyses of data provide good evidence for a variety of hypotheses about behavioral control mechanisms — whether in nonhumans or in humans. For instance, the work of Gangestad and Thornhill on evolved mate preferences and fluctuating asymmetry of body type (FA) is a model of success. As the quantity and quality of evidence increase, we are entitled not just to regard such evolutionary hypotheses as preferable, but also as true. Such studies combine to show that the best explanation of the psychic unity of humankind — common patterns across societies, history, and cultures exposed by evolutionists — is the gendered, adapted, evolved species-typical design of the mind.

Nature exhibits a rich variety of adaptations. Cells contain complex biomolecular structures, such as proteins, that are exquisitely adapted to perform specific biological functions. Evolutionary biology explains how biomolecular structures evolve. Intelligent design creationists reject evolutionary explanations. They want to believe that all adaptations in nature are the handiwork of God. Their critics aver that “it ain't necessarily so.” The anthology under review is an excellent display of the issues between intelligent design creationists and their critics. I agree with the (...) critics. (shrink)
According to an old and attractive view, vagueness must be eliminated before semantic notions — truth, implication, and so on — may be applied. This view was accepted by Frege, but is rarely defended nowadays.1 This..
It is nearly universally acknowledged among epistemologists that a belief, even if true, cannot count as knowledge if it is somehow largely a matter of luck that the person so arrived at the truth. A striking feature of this literature, however, is that while many epistemologists are busy arguing about which particular technical condition most effectively rules out the offensive presence of luck in true believing, almost no one is asking why it matters so much that knowledge be immune from (...) luck in the first place. I argue that the best explanation for the consensus that luck undermines knowledge is that knowledge is, complications aside, credit-worthy true believing. To make this case, I develop both the notions of luck and credit, and sketch a theory of knowledge in those terms. Furthermore, this account also holds promise for being able to solve the “value problem” for knowledge, and it explains why both internal and external conditions are necessary to turn true belief into knowledge.

Stephen Pinker sets out over a dozen arguments in The language instinct (Morrow, New York, 1994) for his widely shared view that natural language is inadequate as a medium for thought. Thus he argues we must suppose that the primary medium of thought and inference is an innate propositional representation system, mentalese. I reply to the various arguments and so defend the view that some thought essentially involves natural language. I argue mentalese doesn't solve any of the problems Pinker cites (...) for the view that we think in natural language. So I don't think I think the way he thinks I think. (shrink)
After a brief account of the problem of higher-order vagueness, and its seeming intractability, I explore what comes of the issue on a linguistic, contextualist account of vagueness. On the view in question, predicates like ‘borderline red’ and ‘determinately red’ are, or at least can be, vague, but they are different in kind from ‘red’. In particular, ‘borderline red’ and ‘determinately red’ are not colours. These predicates have linguistic components, and invoke notions like ‘competent user of the language’. On my (...) view, so-called ‘higher-order vagueness’ is actually ordinary, first-order vagueness in different predicates. I explore the possibility that, nevertheless, a pernicious regress ensues.

Deciding on a topic for the Presidential Address is no easy task. There seem to be a number of models. First, the light philosophical pastiche – the philosophical equivalent of a soufflé. Not only has that been done before1, but I could not think of a subject. Second, the standard philosophical paper, focusing in tightly on some tiny part of the picture – but there are plenty of those around (too many, as I shall later argue!) and, in any case, (...) a Presidential Address appears to demand something special. Third, the philosophical world-view, panning back to get the whole picture. That might better fit the special nature of the occasion, but it is beyond my skill to outline the big picture in a small compass. Fourth, the humorous after-dinner speech, full of wit, satire, and repartee. My predecessor, Greg Ray, delivered the perfect example last year, and one cannot improve on perfection. So that leaves what we might call the broad rumination, the reflective musing on the state of the discipline. The style of pondering whose generic title might be: Whither Philosophy? This genre is beset with dangers, as Greg so wittily showed us. It is hard to avoid being pompous, vacuous, or fatuous – or even all three at once. But I’ll have to risk that. I had been wondering for a while why I find a good deal of contemporary philosophy so tedious when someone drew my attention to a column by Jo Wolff (Head of the Philosophy Department at University College London) in a British newspaper. It begins. (shrink)
The consequence argument is at the core of contemporary incompatibilism about causal determinism and freedom of action. Yet Helen Beebee and Alfred Mele have shown how, on a Humean conception of laws of nature, the consequence argument is unsound. Nonetheless, this paper describés how, by generalising their main idea, we may restore the essential point and force (whatever that might turn out to be) of the consequence argument. A modified incompatibilist argument — which will be called the so-far consequence argument (...) — may thus be derived. (shrink)
Why should science be so interested in discovering whether p is a law over and above whether p is true? The answer may involve the laws' relation to counterfactuals: p is a law iff p would still have obtained under any counterfactual supposition that is consistent with the laws. But unless we already understand why science is especially concerned with the laws, we cannot explain why science is especially interested in what would have happened under those counterfactual suppositions consistent with (...) the laws. It is argued that the laws form the only non-trivially "stable" set, where "stability" is invariance under a certain range of counterfactual suppositions not itself defined by reference to the laws. It is then explained why science should be so interested in identifying a non-trivially "stable" set: because of stability's relation to the best set of "inductive strategies". (shrink)
Kant, having identified the formulas of the supreme principle of morality, offers a succinct explanation of their interrelation. What Kant says is, “The above three ways of representing the principle of morality are at bottom only so many formulae of the very same law, and any one of them of itself unites the other two in it.”1 This claim – hereafter the “Unity Claim” – plays the role of the eccentric cousin in the family of Kant’s ethics: although glaringly present, (...) it is little spoken of, but seldom disowned. Most commentators, at any rate, focus their attention on more important matters, such as the content of the individual formulas, the moral psychology, or the deduction of freedom. Such matters are sufficiently absorbing to leave the Unity Claim often passed over without remark. But the Unity Claim should not be ignored. Kant does assert it, which compels us to attempt to find a place for it in his moral theory. It would seem to constrain the interpretation of the other, more momentous issues. How one interprets the content of the categorical imperative, in particular, would seem to be significantly restricted by the Unity Claim; one could not, given the Unity Claim, offer a complete interpretation of any single formula without also at least referring to the other formulas. And, as I shall argue in Part III below, the Unity Claim is no accident. Kant is committed to the Unity Claim by virtue of some basic features of his moral theory. This paper will thus offer what amounts to an extended commentary on the Unity Claim. I shall review the various suggestions of what it might mean, and how it might, or might not, be accommodated within Kant’s moral theory. The structure of this paper will be as such. Part II will examine the two main strategies for including the Unity Claim within Kant’s moral theory, and explain why they are both inadequate. Part III will examine the other main approach to the 2 Unity Claim: giving up on it.. (shrink)
Roy Sorensen advances an evolutionary explanation of our capacity for thought experiments which doubles as a naturalized epistemological justification. I argue Sorensens explanation fails to satisfy key elements of environmental-selectionist explanations and so fails to carry epistemic force. I then argue that even if Sorensen succeeds in showing the adaptive utility of our capacity, he still fails to establish its reliability and hence epistemic utility. I conclude Sorensens account comes to little more than a just-so story.
The view that properties have their causal powers essentially, which I will here call property essentialism, has advocates in Chris Swoyer,[1] Sydney Shoemaker [2], Alan Chalmers [3], Brian Ellis [4] and Caroline Lierse [5], among a few other authors in recent literature. I am partial to this view as well and I will shortly explain the grounds I find compelling in favor of it. However, we will also see that the essentialist view of properties and laws does not adequately do (...) quite so much as might be hoped. Property essentialism has the straightforward result that at least causal laws are metaphysically necessary. A natural view of such laws is that they are analyses of the essential nature of basic properties in terms of their essential causal powers. Brian Ellis proposes that conservation laws and other laws that may not be exactly causal are best thought of as characterizing the essential properties of worlds. But this further essentialist thesis is not directly relevant to the issues I want to address here. (shrink)
The intimate relationship between X and Y consists in the existence of (metaphysically) necessary truths correlating their occurrences/existences/instantiations.

In that sense, he is not (...) ‘morally free’. (shrink)
In my (2004), I argued that it is possible to drink any finite amount of alcohol without ever suffering a hangover by completing a certain kind of supertask. Assume that a drink causes drunkenness to ensue immediately and to last for a period proportional to the quantity of alcohol consumed; that a hangover begins immediately at the time the drunkenness ends and lasts for the same length of time as the drunkenness; and that at any time during which you are (...) drunk you do not suffer any hangover you might have at that time. Starting at a time at which you are not drunk and not hung over, drink a half pint of beer. Wait until you are just about to get a hangover (30 minutes, say), and then drink a quarter pint. Wait until you are just about to get a hangover again, and then drink an eighth, and so on.... After an hour you have drunk a pint, and you do not have a hangover. Every hangover you incurred happened within the hour you spent drinking; but you were drunk that whole time, so you didn’t suffer the hangovers. It seems that the old drunkard’s method of a “hair of the dog” can be effective in completely avoiding a hangover. (shrink)
Human beings think of themselves in terms of a privileged non-descriptive designator — a mental “I”. Such thoughts are called “de se” thoughts. The mind/body problem is the problem of deciding what kind of thing I am, and it can be regarded as arising from the fact that we think of ourselves non-descriptively. Why do we think of ourselves in this way? We investigate the functional role of “I” (and also “here” and “now”) in cognition, arguing that the use of (...) such non-descriptive “reflexive” designators is essential for making sophisticated cognition work in a general-purpose cognitive agent. If we were to build a robot capable of similar cognitive tasks as humans, it would have to be equipped with such designators. Once we understand the functional role of reflexive designators in cognition, we will see that to make cognition work properly, an agent must use a de se designator in specific ways in its reasoning. Rather simple arguments based upon how “I” works in reasoning lead to the conclusion that it cannot designate the body or part of the body. If it designates anything, it must be something non-physical. However, for the purpose of making the reasoning work correctly, it makes no difference whether “I” actually designates anything. If we were to build a robot that more or less duplicated human cognition, we would not have to equip it with anything for “I” to designate, and general physicalist inclinations suggest that there would be nothing for “I” to designate in the robot. In particular, it cannot designate the physical contraption. So the robot would believe “I exist”, but it would be wrong. Why should we think we are any different? (shrink)

that there is something rationally or conceptually defective in judging that an act is right without being in any way motivated towards it—is one which has tended to lead either to error theories of ethics on the one hand, or acceptance of the truth of internalism on the other. This paper argues that it does play a kind of subject-setting role, but that our responses to cases can be rationalised without requiring that internalism is true for ethical realism to be (...) vindicated. Instead what is required is that something like internalism be believed to be true. The widespreadness of the internalist intuition is part of what makes it the case that some actions are right and others wrong. Of course these beliefs might be false—as the present author holds—consistent with ethical realism, just so long as they are widely held, and whatever else it takes to vindicate realism is the case. In such a situation, widespread false belief would be part of what makes it so that some acts are right, and others wrong. (shrink)
In this paper I give considerable attention to Richard Rorty's attempt to make plausible a conception of non-rational semantic and cultural change - change which Rorty insists on describing as identical with progress - in order to show the extent to which this attempt is compromised from the start by an unjustifiably narrow and inconsistent view of reason. The point of this immanent critique is not just to make Rorty's view of non-rational change look bad. It is meant to do (...) more justice to his claim that intellectual and moral progress is inseparable from speaking and acting differently by incorporating this claim into a philosophically enlarged picture of reason. So the value of taking Rorty's claims about change seriously lies less in showing the shortcomings of his conception of reason than it does in bringing a sense of urgency to the need to renew the project begun by Kant, Hegel, and German Idealism - the project of conceiving reason as an agency of change by reinterpreting reason in terms of self-determining freedom.

Preferentism is the doctrine that "in deciding what is good and what is bad for a given individual, the ultimate criterion can only be his own wants and his own preferences."

In this article, I review and expand upon arguments showing that Freedman's so-called "clinical equipoise" criterion cannot serve as an appropriate guide and justification for the moral legitimacy of carrying out randomized clinical trials.

But a misleading impression is given that, rather than distinct criteria being arbitrarily conflated, a puzzle is solved and a number of features unified. Various issues are pushed under the rug, hiding flaws of the "clinical equipoise" approach and thus deceiving us into thinking that we have a solution when we do not. Particularly significant is the ignoring of the crucial distinction between the individual patient decision and the policy decision. (shrink)

I argue that what’s so bad (qua film fiction) about the cinematic practice of actor-character race-mismatching—be it the historically infamous and intuitively repugnant practice of blackface or one of its more contemporary kin—is that the extent to which film-fictions employ such practices is typically the extent to which such film-fictions unrealistically depict facts about race. More precisely, I claim that race-mismatching film fictions—understood as a species of unrealistic fiction—are prima facie inconsistent fictions with the capacity to mislead their audiences about (...) certain morally relevant actual-world states-of-affairs and thus, prima facie aesthetically, epistemically, and morally defective.

Pretheoretically, truth is a correspondence between a sentence and facts. Other so-called theories of truth have typically been resorted to because such a correspondence is thought of as being inexpressible or as being incapable of yielding a definition of truth which expresses what we actually mean.

As soon as this is corrected, as in independence-friendly first-order logic, truth (...) predicates are readily definable, Tarski notwithstanding. Hence, there is no reason to think that truth cannot also be defined for our actual working language—Tarski’s “colloquial language.”. (shrink)
Qualitative inquiry is increasingly used to foster change in health policy and practice. Research ethics committees often misunderstand qualitative inquiry, assuming its design can be judged by criteria of quantitative science. Traditional health research uses scientific realist standards as a means-to-an-end, answering the question “So what?” to support the advancement of practice and policy. In contrast, qualitative inquiry often draws on constructivist paradigms, generating knowledge either as an end-in-itself or as a means to foster change. When reviewers (...) inappropriately judge qualitative inquiry, it restricts the ways health phenomena can be understood. Qualitative inquiry is necessary because it enables an understanding not possible within scientific explanation. When such research illuminates, it can also shed light onto the “So what?” In order to ensure an appraisal of qualitative inquiry congruent with its paradigmatic premises, we suggest the “Illumination Test,” met when findings foster rich understanding of phenomena, resulting in a reflective “aha!”.

To operationalize the methodological assessment of evolutionary psychology, three requirements are proposed that, if satisfied, would show that a hypothesis is not a just-so story: (1) theoretical entrenchment (i.e., that the hypothesis under consideration is a consequence of a more fundamental theory that is empirically well-confirmed across a very wide range of phenomena), (2) predictive success (i.e., that the hypothesis generates concrete predictions that make it testable and eventually to a certain extent corroborated), and (3) failure of rival explanations (i.e., (...) that crucial and successful predictions attributed to the hypothesis in question cannot be derived from alternative hypotheses). The author argues that the hypothesis about evolutionary sex differences in human jealousy satisfies all three requirements. Key Words: evolutionary psychology • adaptationism • philosophy of science • testability. (shrink)
Abstract Curiously missing in the vast literature on Hilary Putnam's so-called model-theoretic argument against semantic realism is any response from would-be proponents of what Putnam would call magical theories of reference. Such silence is surprising in light of the fact that such theories have occupied a significant position in the history of philosophy and the fact that there are still several prominent thinkers who would, no doubt, favor such a theory. This paper develops and examines various responses to Putnam's argument (...) on behalf of the proponent of a magical theory of reference. While Putnam's explicit replies to such responses to his argument seem to involve little more than name calling, I develop arguments that show that there are significant problems facing any would-be proponent of such a view. While magical theories of reference are far from the strawmen Putnam seems to take them to be, there are, I argue, genuine reasons for a semantic realist to prefer a non-magical theory of reference.

This article entitled “History's `So it seems'” explores the potential of phenomenology for the framing of histories which privilege partcipant perspectives. The theory agenda of the article adapts insights drawn from Heidegger's ontological hermeneutic of Da-sein - the human condition of being-there and being-aware (or not aware). The theory agenda also adapts Heidegger's readings of Heraclitus. The practical agenda of the article illustrates this potential of Heidegger's phenomenology for history by contrasting `so it once seemed' senses of the Emperor Julian (...) the Apostate's Roman pagan self-hood. The contrasts are autobiographical (Julian's Misopogon ), contemporary biographical (Ammianus Marcellinus's history), and long-lag biographical (Gore Vidal's novel avowedly constrained by the sources).

Atran advances three theses: our folk-biological taxonomy is (1) universal, (2) innate, and (3) the product of natural selection. I argue that Atran offers insufficient support for theses (2) and (3) and that his evolutionary psychology thus amounts to nothing more than a just-so story.

Why has it been so difficult to integrate paleontology and mainstream evolutionary biology? Two common answers are: (1) the two fields have fundamentally different aims, and (2) the tensions arise out of disciplinary squabbles for funding and prestige. This paper examines the role of fossil data in phylogeny reconstruction in order to assess these two explanations. I argue that while cladistics has provided a framework within which to integrate fossil character data, the stratigraphic (temporal) component of fossil data has been (...) harder to integrate. A close examination of how fossil data have been used in phylogeny reconstruction suggests that neither explanation is adequate. While some of the tensions between the fields may be intellectual turf wars, the second explanation downplays the genuine difficulty of combining the distinctive data of the two fields. Furthermore, it is simply not the case that the two fields pursue completely distinct aims. Systematists do disagree about precisely how to represent phylogeny (e.g., minimalist cladograms or trees with varying levels of detail) but given that every tree presupposes a pattern of branching (a cladogram), these aims are not completely distinct. The central problem has been developing methods that allow scientists to incorporate the distinctive bodies of data generated by these two fields. Further case studies will be required to determine if this explanation holds for other areas of interaction between paleontology and neontology. (shrink)
NC: 'Rogue State' is used here to refer to any state that is disobedient, that the US has in the sights of its rifles. But the term really has a meaning: a rogue state is a state that defies international law, international norms and conventions, that demands the right to do anything it wants, pays no attention and doesn't care about the opinions and attitudes of others who stand in its way, and so on.
The paper considers René Descartes’ assertion that believing that God exists because the Bible says so, and believing that what the Bible says is true because God says it, involves circular reasoning. It argues that there is no circularity involved in holding these beliefs, and maintains that the appearance of circularity results from an equivocation. It considers a line of argument that would defend the rationality of holding these beliefs, but does not try to prove its soundness.
The debate about ECT in Ireland in recent times has been vibrant and often polarised. The uniqueness of the Irish situation is that the psychiatric profession is protected by legislation whereby ECT treatment can be authorized by two consultant psychiatrists without the consent of the patient. This paper will consider if ECT is ever ethically justified, and if so, under what circumstances. The proposal is to investigate ECT from an ethical perspective with reference to the UNESCO Universal Declaration on Bioethics (...) and Human Rights. The enquiry will begin with an historical context to the origin and development of ECT as a treatment for severe mental illness. The application of various ethical principles will be considered in conjunction with the relevant literature before arriving at a conclusion. (shrink)
This paper argues that an important feature of Locke's doctrine concerning primary and secondary qualities is also central to Hume's thinking. Section one considers Locke's distinction, presenting it in terms of an "error theory." Locke argues that we attribute secondary qualities to objects and that in so doing give those qualities an ontological status they do not otherwise possess. Locke completes his theory by drawing on the concept of "resemblance" to explain why such mistakes occur in the first place. Section (...) two turns to Hume's philosophy, arguing that, despite his ambiguous comments on Locke and "the modern philosophy," he employs an error theory of the sort developed by Locke. This contention is supported by way of Hume's treatment of beauty as a secondary quality or sentiment which arises in an individual who judges an object beautiful. The paper concludes by emphasizing that, for Hume, this philosophical explanation of beauty stands in contrast to the error committed in common life where, as in Locke's account, people make the mistake of taking beauty to be in the object itself.

Facial responses to pain might be the result of evolution but Williams' interesting “Just So” story provides no convincing evidence for her hypothesis. Contrary to her hope, casting facial action in an evolutionary perspective will probably not reduce the common practice of health care professionals blaming patients for their problems; instead, it may discourage appropriate treatment.
According to the classical Doctrine of Double Effect (DDE), there is a morally significant difference between intending harm and merely foreseeing harm. Versions of DDE have been defended in a variety of creative ways, but there is one difficulty, the so-called “closeness problem”, that continues to bedevil all of them. The problem is that an agent's intention can always be identified in such a fine-grained way as to eliminate an intention to harm from almost any situation, including those that have (...) been taken to be paradigmatic instances in which DDE applies to intended harm. In this paper, we consider and reject a number of recent attempts to solve the closeness problem. We argue that the failure of these proposals strongly suggests that the closeness problem is intractable, and that the distinction between intending harm and merely foreseeing harm is not morally significant. Further, we argue that there may be a deeper reason why such attempts must fail: the rationale that makes the best fit with DDE, namely, an imperative not to aim at evil, is itself irredeemably flawed. While we believe that these observations should lead us to abandon further attempts to solve the closeness problem for DDE, we also conclude by showing how a related principle that is supported by a distinct rationale and avoids facing the closeness problem altogether nevertheless shares with DDE its most important features, including an intuitive explanation of a number of cases and a commitment to the relevance of intentions.

A viatical settlement (or viatical) is a transaction in which an investor purchases the life insurance policy from a terminally ill person for a lump sum so that the investor can receive those benefits at the time of death. While there is an ongoing debate in the insurance and financial planning industry about viaticals, including the ethics of this practice, the focus has been predominantly on abuses in the course of buying and selling viaticals and less on the fundamental ethicality (...) of the economic idea behind viaticals. This paper offers a systematic ethical analysis of viaticals that leverages the distinction between the ethicality of an economic idea and the ethicality of economic reality to isolate and discuss the fundamental ethical problems of viaticals. By unpacking the evaluative content of our negative emotional reactions to viaticals, we show that, even under ideal circumstances, the economic idea of viaticals is, at its core, unethical. (shrink)
Two broad metaphysical perspectives deriving from Parmenides and Heraclitus have implications for our notion of sustainability. The Parmenidian defends a deepseated orderliness and permanence in things, while the Heraclitian finds only chance and change. Two further outlooks, the nomic (or the big-picture scientific) and the prudential, present differing accounts of our place in the world. While the nomic outlook accepts nothing privileged about the human perspective or even life itself, the prudential outlook is obviously welfare-centered. It is argued that nomic (...) views, whether Parmenidian or Heraclitian, fail to provide any rationale for sustainability measures or concerns. The only such rationale comes from Parmenidian prudentialism, which, I argue, can operate only if it disowns at its peril the nomic point of view and couches sustainability entirely under the rubric of maximizing certain preferred opportunities drawn from collective self-love. But doing so merely evades rather than answers the tension imposed by the nomic Heraclitian for whom nothing lasts and nothing human counts specially in the measure. The liabilities of Parmenidian prudentialism are examined and found to be too great for any consistent notion of sustainability to bear. (shrink)

While every discipline in the humanities worries about its future, film studies is caught in the thrall of a particular anxiety, namely the possibility that it lacks a consistent object and a compelling reason. Behind the question of film studies looms the question of cinema itself, an aging techn? that seems to have hung around in the midst of new(er) media that lay claim to the image as their province. Why cinema? Against so many digital incursions, more traditionally minded critics (...) have defended film on the basis of its indexical powers, but this article envisions an entirely different reason to return to the cinema. Where both the return to the index and the recourse to the digital effect tend to regard the cinema as a matter of visibility, I suggest that we might reclaim our faith in the cinema by virtue of what remains unseen and off-screen. Hence, this essay undertakes a brief history of the out of frame in order to induce a conceptualization of the cinema (pace Deleuze) as the art of the ?Outside.? Turning to Stanley Kubrick's 2001: A Space Odyssey, the essay concludes by analyzing how an ostensibly older sense of images nevertheless augurs the critical and philosophical developments with which we can learn to believe in the cinema once more.

It is very well known that from the late-1960s onwards Feyerabend began to radically challenge some deeply-held ideas about the history and methodology of the sciences. It is equally well known that, from around the same period, he also began to radically challenge wider claims about the value and place of the sciences within modern societies, for instance by calling for the separation of science and the state and by questioning the idea that the sciences served to liberate and ameliorate (...) human societies. But what is less known is how, if at all, these two sets of challenges were connected, and why Feyerabend felt it important to raise them at all. In this chapter, my aim is to explore these issues by considering why Feyerabend used radical strategies to challenge the authority of science, and what purpose, if any, they were supposed to serve. Why, for instance, did Feyerabend defend alternative medicine, psychical abilities, astrology, magic and witchcraft and why did he argue that ‘Western science’ is complicit in environmental destruction, intellectual imperialism, social oppression, and spiritual destitution. Located in their historical and political context, such defences and arguments seem peculiar, not least because science was recognised not only as a central site of the intellectual and ideological competition between the West and the Soviet Union, but also because Western victory in that site was considered inevitable. What, then, did Feyerabend think he was trying to achieve by raising radical challenges to a central component of the cultural and intellectual prestige of the Western world grounded in appeals to practices and traditions which most would regard as eccentric at best and absurd at worst? My suggestion is that Feyerabend was making a subtler point than one might suppose. For the purpose of these radical challenges was to determine if the members of Western societies would in fact honour the epistemic standards – of tolerance, critical enquiry – which were identified as being characteristic of science and definitive of the social and political values of Western liberal democracy. I suggest that Feyerabend was trying to demonstrate that scientists were, too often, guilty of the same intolerant and dogmatic attitudes which were, according to prevailing propaganda, the property of illiberal totalitarian societies. Science does not reflect the superior epistemic and political values of Western societies but are, in fact, reflective of the same vices ascribed to the Soviet Union. If that is the case, then the sciences are not symbols of our epistemic and political values, but quite the reverse, hence Feyerabend’s talk of the ‘dogmatic’, ‘totalitarian’, ‘ratiofascist’ nature of modern science. But there is a positive upshot to Feyerabend’s challenge. For even if the sciences do not yet reflect the epistemic and political values of liberal democratic Western societies, they might yet be reformed so that they are. And there is a parallel between Feyerabend’s strategy and that of many of the other radicals of the time – student activists, environmentalists, and pacifists – namely to test the commitment to tolerance and deliberative debate of the establishment by asking it to seriously engage with ideas and convictions opposed to its own. For both science and society can become ‘tyrannical’ through the same means: by exempting themselves from critical scrutiny, by promoting self-serving ‘myths’ about themselves, and by derogating and excluding alternatives, including the ‘outsider’ perspectives they offer. The chapter concludes by suggesting that Feyerabend is distinctive in virtue of his willingness to offer radical criticisms of the authority of science such that it can fulfil its legitimate ideological role – namely, of symbolising and instantiating our core epistemic and political values – such that we can offer a sincere and meaningful answer to Feyerabend’s question ‘what’s so great about science?’.

Many people, including many egalitarian political philosophers, professa belief in equality while enjoying high incomes of which they devotevery little to egalitarian purposes. The article critically examinesways of resolving the putative inconsistency in the stance of thesepeople, in particular, that favouring an egalitarian society has noimplications for behaviour in an unequal one; that what''s bad aboutinequality is a social division that philanthropy cannot reduce; thatprivate action cannot ensure that others have good lives; that privateaction can only achieve a ``drop in (...) the ocean''''; that private effortis not called for, since justice is a matter for the state to enforce;that private effort cannot remove the fundamental injustice, whichis inequality of power; and that private effort involves an unreasonablylarge psychological burden.

Intuitions about the transparency of experience have recently begun to play a key role in the debate about qualia. Specifically, such intuitions have been used by representationalists to support their view that the phenomenal character of our experience can be wholly explained in terms of its intentional content.[i] But what exactly does it mean to say that experience is transparent? In my view, recent discussions of transparency leave matters considerably murkier than one would like. As I will suggest, there is (...) reason to believe that experience is not transparent in the way that representationalism requires. Although there is a sense in which experience can be said to be transparent, transparency in this sense does not give us any particular motivation for representationalism—or at least, not the pure or strong representationalism that it is usually invoked to support.

It has often been thought that our knowledge of ourselves is _different_ from, perhaps in some sense _better_ than, our knowledge of things other than ourselves. Indeed, there is a thriving research area in epistemology dedicated to seeking an account of self-knowledge that would articulate and explain its difference from, and superiority over, other knowledge. Such an account would thus illuminate the descriptive and normative difference between self-knowledge and other knowledge.<sup>1</sup> At the same time, self- knowledge has also encountered its (...) share of skeptics – philosophers who refuse to accord it any descriptive, let alone normative, distinction. In this paper, we argue that there is at least one _species_ of self-knowledge that is different from, and better than, other knowledge. It is a specific kind of knowledge of one’s concurrent phenomenal experiences. Call knowledge of one’s own phenomenal experiences _phenomenal knowledge_. Our claim is that some (though not all) phenomenal knowledge is different from, and better than, non-phenomenal knowledge. In other. (shrink)
“The genealogy of morals” is, most famously, a pair of genealogies: that of the good/evil dichotomy in the First Treatise, and that of the bad conscience in the Second Treatise. But the straightforward presentation of these two narratives is subverted even before it begins. Nietzsche classifies the book not as a treatise or inquiry but as a “polemic”; voices interrupt the narrative to insist that much is left unsaid; the narratives are framed by, of all things, reflections on the scientific (...) conscience; Nietzsche declares the entire enterprise to be a contribution to the critique of “the value of values”; the two genealogies of the first two Treatises overlap and various points and ultimately converge in a discussion of the “meaning” of the “ascetic ideal.” Whatever one makes of these complications, two tentative conclusions can be drawn. Nietzsche is profoundly concerned with the status of his genealogy. And genealogy does not function as reportage, primarily concerned with the accurate depiction of events; rather, it aims to reveal something about the status of “moral values” and the possibility of an alternative to them.

The article is part of a symposium on Hartry Field’s “Saving truth from paradox”.

The literature on conscience in medicine has paid little attention to what is meant by the word ‘conscience.’ This article distinguishes between retrospective and prospective conscience, distinguishes synderesis from conscience, and argues against intuitionist views of conscience. Conscience is defined as having two interrelated parts: (1) a commitment to morality itself; to acting and choosing morally according to the best of one’s ability, and (2) the activity of judging that an act one has done or about which one is deliberating (...) would violate that commitment. Tolerance is defined as mutual respect for conscience. A set of boundary conditions for justifiable respect for conscientious objection in medicine is proposed. (shrink)
According to a widespread view, a complete explanatory reduction of all aspects of the human mind to the electro-chemical functioning of the brain is at hand and will certainly produce vast and positive cultural, political and social consequences. However, notwithstanding the astonishing advances generated by the neurosciences in recent years for our understanding of the mechanisms and functions of the brain, the application of these findings to the specific but crucial issue of human agency can be considered a “pre-paradigmatic science” (...) (in Thomas Kuhn’s sense). This implies that the situation is, at the same time, intellectually stimulating and methodologically confused. More specifically—because of the lack of a solid, unitary and coherent methodological framework as to how to connect neurophysiology and agency—it frequently happens that tentative approaches, bold but very preliminary claims and even clearly flawed interpretations of experimental data are taken for granted. In this article some examples of such conceptual confusions and intellectual hubris will be presented, which derive from the most recent literature at the intersection between neurosciences, on the one hand, and philosophy, politics and social sciences, on the other hand. It will also be argued that, in some of these cases, hasty and over-ambitious conclusions may produce negative social and political consequences. The general upshot will be that very much has still to be clarified as to what and how neurosciences can tell us about human agency and that, in the meantime, intellectual and methodological caution is to be recommended.

Human beings think of themselves in terms of a privileged non-descriptive designator — a mental “I”. Such thoughts are called “_de se_” thoughts. The mind/body problem is the problem of deciding what kind of thing I am, and it can be regarded as arising from the fact that we think of ourselves non-descriptively. Why do we think of ourselves in this way? We investigate the functional role of “I” (and also “here” and “now”) in cognition, arguing that the use of (...) such non-descriptive “reflexive” designators is essential for making sophisticated cognition work in a general-purpose cognitive agent. If we were to build a robot capable of similar cognitive tasks as humans, it would have to be equipped with such designators. (shrink)
Political philosophers have been concerned for some time with the epistemic caliber of the general public, qua the body that is, ultimately, tasked with political decision-making in democratic societies. Unfortunately, the empirical data paints a pretty dismal picture here, indicating that the public tends to be largely ignorant on the issues relevant to governance. To make matters worse, social psychological research on how ignorance tends to breed overconfidence gives us reason to believe that the public will not only lack knowledge (...) on the relevant issues, but also wisdom, in the Socratic sense of an awareness of your ignorance. It might be thought that an obvious remedy would be to increase the knowledge and wisdom of the public. However, as far as sound political decision-making and action is concerned, there is nothing particularly valuable about knowledge or wisdom per se—irrespective of what account of wisdom available in the literature we opt for. In fact, it might just be that what the public needs is nothing but the most basic epistemic good: true belief. (shrink)

This collection of seventeen brand new essays critically examines just how and in what form the notion of imagination illuminates fundamental problems in the philosophy of art. (shrink)
Throughout Wittgenstein had Frege in mind. We should too, to understand him. This is as true for Philosophical Investigations as for the Tractatus. In fact, the later work is, in an important way, closer to Frege than the first—even though the Investigations makes a target of what seems a central Fregean idea. It directs Frege’s own ideas at that target, using something deeply right in Frege to undo a misreading of what, rightly read, are mere truisms.
According to the conventional wisdom, Turing (1950) said that computing machines can be intelligent. I don''t believe it. I think that what Turing really said was that computing machines –- computers limited to computing –- can only fake intelligence. If we want computers to become genuinelyintelligent, we will have to give them enough initiative (Turing, 1948, p. 21) to do more than compute. In this paper, I want to try to develop this idea. I want to explain how giving computers (...) more ``initiative'''' can allow them to do more than compute. And I want to say why I believe (and believe that Turing believed) that they will have to go beyond computation before they can become genuinely intelligent. (shrink)
This dissertation is on infinite regress arguments in philosophy. Its main goals are to explain what such arguments from many distinct philosophical debates have in common, and to provide guidelines for using and evaluating them. Two theories are reviewed: the Paradox Theory and the Failure Theory. According to the Paradox Theory, infinite regress arguments can be used to refute an existentially or universally quantified statement (e.g. to refute the statement that at least one discussion is settled, or the statement that (...) discussions are settled only if there is an agreed-upon criterion to settle them). According to the Failure Theory, infinite regress arguments can be used to demonstrate that a certain solution fails to solve an existentially or universally quantified problem (e.g. to demonstrate that a certain solution fails to settle all discussions, or that it fails to settle even one discussion). In the literature, the Paradox Theory is fairly well-developed, and this dissertation provides the Failure Theory with the same tools. (shrink)
The presence of spatial patterns of activity in the brain is suggestive of image-exploiting processes in vision and mental imagery, but not conclusive. Only behavioral evidence can confirm or disconfirm hypotheses about whether, and how, the brain uses images in its information-processing, and the arguments based on such evidence are still inconclusive.
It is a common assumption in the metaphysics of time that a commitment to presentism entails a commitment to serious presentism, the view that objects can exemplify properties or stand in relations only at times at which they exist. As a result, non-serious presentism is widely thought to be beyond the bounds for the card-carrying presentist in response to the problem of cross-temporal relations. In this paper, I challenge this general consensus by examining one common argument in favor of the (...) thesis that presentism entails serious presentism. The argument, I claim, begs the question against non-serious defenders in failing to account for their wider metaontological views concerning non-committal quantification. (shrink)
Humans clearly have trouble thinking about death. This trouble is often used to explain behavior like delay in writing wills or buying life insurance, or interest in odd medical and religious beliefs. But the problem is far worse than most people imagine. Fear of death makes us spend fifteen percent of our income on medicine, from which we get little or no health benefit, while we neglect things like exercise, which offer large health benefits.
