I discuss Ingmar Persson’s recent argument that the Levelling Down Objection could be worse for prioritarians than for egalitarians. Persson’s argument depends upon the claim that indifference to changes in the average prioritarian value of benefits implies indifference to changes in the overall prioritarian value of a state of affairs. As I show, however, sensible conceptions of prioritarianism have no such implication. Therefore prioritarians have nothing to fear from the Levelling Down Objection.

The paper returns to the question whether equality in distribution is valuable in itself, or, if you like, whether it is intrinsically valuable. Its bulk is an examination of two familiar arguments against the intrinsic value of distributional equality: the levelling down objection and the objection that equality violates some person-affecting condition, in that its realisation does not improve the lot of people.

The levelling down objection is the most serious objection to the principle of equality, but we think it can be conclusively defeated. It is serious because it pits the principle of equality squarely against the welfares of the persons whose welfares or resources are equalized. It suggests that there is something perverse about the principle of equality. In this paper, we argue that levelling down is not an implication of the principle of equality. To (...) show this we offer a defence of, and partial elaboration of, what we call a common good conception of the principle of equality, which principle favours states in which everyone is better off to those in which everyone is worse off. We contrast this with what we call a purely structural conception of the principle of equality. The common good conception of equality involves two basic components: (1) in each circumstance there exists an ideal egalitarian distribution, which distributes equally all the available good in the distribution with the highest average welfare and (2) in evaluating how just the world is, it will matter how far the actual distribution is from the ideal distribution. The ideal egalitarian distribution in the circumstance is Pareto optimal and the approximation rule implies that Pareto superior states are less unjust than Pareto inferior states. 1. (shrink)

Derek Parfit has argued that, in contrast to prioritarianism, egalitarianism is exposed to the levelling down objection, i.e., the objection that it is absurd that a change which consists merely in the betteroff losing some of their well-being should be in one way for the better. In reply, this paper contends that (1) there is a plausible form of egalitarianism which is equivalent to another form of prioritarianism than the Parfitian one, a relational rather than an (...) absolute form of prioritarianism, and that (2), although this relational or egalitarian form of prioritarianism is hit by the levelling down objection, the Parfitian form is also hit by it, or worse objections, if it is fully worked out.

I have earlier argued that, like egalitarianism, prioritarianism is exposed to the levelling down objection—which I do not find serious—but also that it faces related, more serious objections that egalitarianism avoids. In this paper I reply to Thomas Porter’s attempt to rebut this argument. I also trace the more serious objections to prioritarianism to the fact that it implies the desirability of welfare diffusion, i.e. that it is better all things considered if a quantity of welfare is (...) distributed over as many recipients as possible, so that each recipient gets a minimal benefit, and that the outcome would still be in one respect better, even if the quantity of welfare was reduced. In contrast to egalitarianism, prioritarianism therefore implies that it is in one respect better if an equality, or a solitary individual, is located at lower rather than a higher level of welfare.

Many think that equality is an intrinsic value. However, this view, especially when based on a consequential foundation, faces familiar objections related to the claim that equality is sometimes good for none and bad for some: most notably the levelling down objection. This article explores a unique (consequential) conception of equality, as part of a more general conception of fairness concerning the resolution of interpersonal conflicts, which is not exposed to these objections.

Rationality (or something similar) is usually given as the relevant difference between all humans and animals; the reason humans do but animals do not deserve moral consideration. But according to the Argument from Marginal Cases not all humans are rational, yet if such (marginal) humans are morally considerable despite lacking rationality it would be arbitrary to deny animals with similar capacities a similar level of moral consideration. The slippery slope objection has it that although marginal humans are not strictly (...) speaking morally considerable, we should give them moral consideration because if we do not we will slide down a slippery slope where we end up by not giving normal humans due consideration. I argue that this objection fails to show that marginal humans have the kind of direct moral status proponents of the slippery slope argument have in mind. (shrink)

This paper aims to illuminate some issues in the equality, priority, or what debate. I characterize egalitarianism and prioritarianism, respond to the view that we should care about sufficiency or compassion rather than equality or priority, discuss the levelling down objection, and illustrate the significance of the distinction between prioritarianism and egalitarianism, establishing that the former is no substitute for the latter. In addition, I respond to Bertil Tungodden's views regarding the Slogan, the levelling down (...) objection, the Pareto Principle, leximin, the principle of personal good, strict moderate egalitarianism, the Hammond Equity Condition, the intersection approach, and non-aggregative reasoning.

It is common to define egalitarianism in terms of an inequality ordering, which is supposed to have some weight in overall evaluations of outcomes. Egalitarianism, thus defined, implies that levelling down makes the outcome better in respect of reducing inequality; however, the levelling down objection claims there can be nothing good about levelling down. The priority view, on the other hand, does not have this implication. This paper challenges the common view. The standard (...) definition of egalitarianism implicitly assumes a context. Once this context is made clear, it is easily seen that egalitarianism could be defined alternatively in terms of valuing a benefit to a person inversely to how well off he is relative to others. The levelling down objection does not follow from this definition. Moreover, the common definition does not separate egalitarian orderings from prioritarian ones. It is useful to do this by requiring that on egalitarianism, additively separable orderings should be excluded. But this requirement is stated as a condition on the alternative definition of egalitarianism, from which the levelling down objection does not follow. (shrink)

The Slogan holds that one situation cannot be worse (or better) than another unless there is someone for whom it is worse (or better). This principle appears to provide the basis for the levelling-down objection to teleological egalitarianism. Larry Temkin, however, argues that the Slogan is not a plausible moral ideal, since it stands against not just teleological egalitarianism, but also values such as freedom, rights, autonomy, virtue and desert. I argue that the Slogan is a plausible (...) moral principle, one that provides a suitable moral basis for the levelling-down objection to teleological egalitarianism. Contrary to Temkin, freedom, autonomy, virtue, and rights can all be understood in person-affecting terms, while equality of outcome cannot. Moreover, the Slogan is open to a variety of different ideas about how we should weight or rank people's gains and losses. This flexibility allows the Slogan to accommodate ideals such as prioritarianism and desert. (shrink)

Some people believe that the equality of people's well-being makes an outcome better, other things being constant. Call this Telic Egalitarianism. In this paper I will propose a new interpretation of Telic Egalitarianism, and compare it with the interpretation that is proposed by Derek Parfit 1995 and widely accepted by many philosophers. I will argue that my proposed interpretation is more plausible than Parfit's. One of the virtues in my interpretation is that it shows his Levelling Down (...) class='Hi'>Objection does not undermine Telic Egalitarianism. I also believe that my interpretation better explains the important similarity and difference between Telic Egalitarianism and his proposed Priority View. (shrink)

Abstract Following Temkin's Inequality I take my point of departure in an individualistic approach according to which a situation is bad in respect of inequality to the extent individuals in it have egalitarian complaints. After having criticised some of Temkin's notions of inequality, I argue that there are two proper egalitarian conceptions, the Equal Share Conception and the Place Conception. The first concerns how much welfare an individual can claim to have in order to have what she should have in (...) virtue of equality. The second concerns an individual's egalitarian complaint in so far as it depends on her place in a situation's distribution of welfare. I argue that the first conception can be employed in a defence of Telic Egalitarianism against Derek Parfit's Levelling Down Objection and that the second one can explain why this objection may seem so convincing. I also argue that Telic Egalitarianism, understood according to the first conception, in one respect is preferable to Parfit's Priority View. (shrink)

Derek Parfit has argued that egalitarianism is exposed to a levelling down objection because it implies, implausibly, that a change, which consists only in the better-off sinking to the level of the worse-off, is in one respect better, though it is better for nobody. He claims that, in contrast, the prioritarian view that benefits to the worse-off have greater moral weight escapes this objection. This article contends, first, that prioritarianism is equally affected by the levelling (...) down objection as is egalitarianism, but that this objection lacks force. Secondly, prioritarianism is less plausible than egalitarianism because it implies that lowering the level of equality by diffusing a quantity of welfare equally over as many recipients as possible is for the better all things considered, and that the outcome of such welfare diffusion would still be better in one respect, even if the quantity of welfare was radically reduced.

Many philosophers have claimed that we might do well to adopt a hybrid theory of well-being: a theory that incorporates both an objective-value constraint and a pro-attitude constraint. Hybrid theories are attractive for two main reasons. First, unlike desire theories of well-being, hybrid theories need not worry about the problem of defective desires. This is so because, unlike desire theories, hybrid theories place an objective-value constraint on well-being. Second, unlike objectivist theories of well-being, hybrid theories need not worry about being (...) overly alienating. This is so because, unlike objectivist theories, hybrid theories place a pro-attitude constraint on well-being. However, from the point of view of objectivists, hybrid theories are not objectivist enough, and this can be seen clearly in missing-desires cases. For instance, hybrid theories entail that, if someone lacks the desire for health, then health is not a component of her well-being. This, objectivists say, is implausible. It is obvious, objectivists say, that someone’s life goes better for herself inasmuch as she is healthy, and hence that health is a component of her welfare. This paper focuses on the missing-desires objection (as leveled by objectivists) to hybrid theories of well-being. My argument is that the missing-desires objection can be answered in a way that is generally convincing and, in particular, in a way that pays a good deal of respect to objectivist intuitions about well-being. My hope, then, is that this paper will help to persuade objectivists about well-being to become hybrid theorists. (shrink)

This style of argument comes up everywhere in the philosophy of practical reason, leveled against theories of the norm of means-end coherence on intention, against Humean theories of reasons, and many other places. It comes up in normative moral theory – for example, in arguments against buck-passing. It comes up in epistemology, in discussions of how to account for the rational connection between believing the premises of a valid argument and believing its conclusion. And it comes up in political philosophy, (...) where one of its most salient occurrences is in the so-called ‘leveling down’ objection to egalitarianism. (shrink)

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

In this paper I consider Saul Kripke’s famous Humphrey objection to David Lewis’s views on de re modality and argue that responses to this objection currently on the market fail to mitigate its force in any significant way.

This paper concerns Alan Turing’s ideas about machines, mathematical methods of proof, and intelligence. By the late 1930s, Kurt Gödel and other logicians, including Turing himself, had shown that no finite set of rules could be used to generate all true mathematical statements. Yet according to Turing, there was no upper bound to the number of mathematical truths provable by intelligent human beings, for they could invent new rules and methods of proof. So, the output of a human mathematician, for (...) Turing, was not a computable sequence (i.e., one that could be generated by a Turing machine). Since computers only contained a finite number of instructions (or programs), one might argue, they could not reproduce human intelligence. Turing called this the “mathematical
objection” to his view that machines can think. Logico-mathematical reasons, stemming from his own work, helped to convince Turing that it should be possible to reproduce human intelligence, and eventually compete with it, by developing the appropriate kind of digital computer. He felt it
should be possible to program a computer so that it could learn or discover new rules, overcoming the limitations imposed by the incompleteness and undecidability results in the same way that human
mathematicians presumably do. (shrink)

A standard criticism of act-utilitarianism is that it is only indirectly concerned with the distribution of welfare between individuals and, therefore, does not take adequate account of the separateness between individuals. In response a number of philosophers have argued that act-utilitarianism is only vulnerable to that objection because it adheres to a theory of the good which ignores non-welfarist sources of intrinsic value such as justice. Fred Feldman, for example, argues that intrinsic value is independently generated by the receipt (...) of welfare and the degree to which receipt accords with the demands of justice, and that an action is right insofar as it maximizes the sum of both those sources of value. In response it is argued that justicized consequentialism only blocks the objection at the expense of presupposing deontological constraints. In addition, it is argued that the value of justice cannot be explained non-deontically and, therefore, that the proposed theory is not consequentialist all the way down. (shrink)

In this paper, I argue that van Fraassen’s “bad lot objection” against Inference to the Best Explanation [IBE] severely misses its mark. First, I show that the objection holds no special relevance to IBE; if the bad lot objection poses a serious problem for IBE, then it poses a serious problem for any inference form whatever. Second, I argue that, thankfully, it does not pose a serious threat to any inference form. Rather, the objection misguidedly blames (...) a form of inference for not achieving what it never set out to achieve in the first place. (shrink)

The Many Gods Objection (MGO) is widely viewed as a decisive criticism of Pascal’s Wager. By introducing a plurality of hypotheses with infinite expected utility into the decision matrix, the wagerer is left without adequate grounds to decide between them. However, some have attempted to rebut this objection by employing various criteria drawn from the theological tradition. Unfortunately, such defenses do little good for an argument that is supposed to be an apologetic aimed at atheists and agnostics. The (...) purpose of this paper is to offer a defensive strategy of a different sort, one more suited to the Wager’s apologetic aim and status as a decision under ignorance. Instead of turning to criteria independent of the Wager, it will be shown that there are characteristics already built into its decision theoretic structure that can be used to block many categories of theological hypotheses including MGO’s more outrageous “cooked-up” hypotheses and “philosophers’ fictions”.

This paper argues that the four most plausible arguments compatible with public reason for an outright legal ban on all forms of polygamy are unvictorious. I consider the types of arguments political liberals would have to insist on, and precisely how strongly, in order for a general prohibition against polygamy to be justified, while also considering what general attitude towards "marriage" and legal recognition of the right to marry are most consistent with political liberalism. I argue that a liberal state (...) should get out of the "marriage business" by leveling down to a universal status of "civil union" neutral as to the gender and affective purpose of domestic partnerships. I then refute what I regard as the four most plausible rational objections to offering this civil union status to multi-member domestic partnerships. The most common objection to polygamy is on grounds of gender equality, more specifically, female equality. But advancing this argument forcefully often involves neglecting the tendency of political liberalism (by whatever name it goes in contemporary, complex, multicultural societies) to tolerate a certain amount of inequality in private, within the bounds of robust and meaningful freedoms of choice and exit. Properly understood, polygamy involves no inherent statement about the essential inferiority of women, and certainly not more than many other existing practices and institutions (including many expressions of the main monotheistic religions) which political liberals regard as tolerable, even reasonable. Arguments from the welfare of children, fairness in the spousal market, and the abuse of family subsidies are also considered and found insufficient for excluding polygamy. (shrink)

In this article, I propose a new way of thinking about natural necessity and a new way of thinking about biological laws. I suggest that much of the lack of progress in making a positive case for distinctively biological laws is that we’ve been looking for necessity in the wrong place. The trend has been to look for exceptionlessness at the level of the outcomes of biological processes and to build one’s claims about necessity off of that. However, as Beatty (...) (1995) observed, even when we are lucky enough to find a biological ‘rule’ of some sort, that rule is apt to be a victim of ‘the rule-breaking capabilities of evolutionary change’. If indeed no distinctively biological generalization—even an exceptionless one—is safe, we need to locate necessity elsewhere. A good place to start is, I think, precisely the point at which Beatty sees the possibility of lawhood as breaking down—namely, at the level of chances. 1 The ‘Necessity’ Objection to Biological Laws2 Necessary Chances2.1 Necessary chances: random drift2.2 Necessary chances: fitness3 But is it Biological?4 Conclusion.

Realist accounts of natural kinds rely on an account of causation where the relata of causal relations are real and discrete. These views about natural kinds entail very different accounts of causation. In particular, the necessity of the causal relation given the instantiation of the properties of natural kinds is more robust in the fundamental sciences (e.g. physics and chemistry) than it is in the life sciences (e.g. biology and the medical sciences). In this paper, I wish to argue that (...) there is a difference in kind between the putative natural kinds of the fundamental sciences and those of the life sciences, such that a uniform account of causation cannot capture both. The upshot is that we must either reject the claim that the kinds of the life sciences are genuine natural kinds, or accept that there are different kinds of causal relations involving the relata of natural kinds. I accept the latter. I reject the objection that the true causal relations that relate macro-level kinds are to be found by “going down a level” to causal relation at the fundamental kind, because the relevant causal mechanisms are not at the fundamental level. Since, autonomous mechanistic accounts of causal relations at the macro-level can be provided (e.g. in Biology and medicine), I argue that realism about the natural kinds of the life sciences is justified. I address the problem of negative causation as a counterexample to the positive account of causation that is entailed by realism about natural kinds in the life sciences. I argue that an acceptance of realist accounts of two different kinds of natural kind makes a uniform analysis of causation look unpromising. (277 words). (shrink)

Gestalt theory is discussed as one main precursor of synergetics, one of the most elaborated theories of self-organization. It is a precursor for two reasons: the Gestalt theoretical view of cognitive order-formation comes dose to the central ideas of self-organization. Furthermore both approaches have stressed the significance of non-linear perceptual processes (such as multistability) for the solution of the mind-brain problem. The question of whether Gestalt theory preferred a dualistic or a monistic view of the mind-body relation is answered in (...) that there was a preference for dualism in epistemological questions and for monism in the mind-brain relation. The latter was attained by the concept of psychophysical isomorphism. This concept, although widely misunderstood in many respects, was criticized on the basis of neurobiological findings. One main objection was the neglect of the importance of the elementary neurophysiological processes. A distinction between macroscopic and microscopic brain processes seemed to be required. This idea was taken up in synergetics which postulates a bottom-up and top-down interaction between these two levels. Macroscopic order emerges from elementary brain processes and, at the same time, has a backward slaving effect to the microscopic level In the light of such holistic emergentism, the question whether macroscopic order states might be attractors for psychological meanings is discussed.

Notwithstanding many similarities between Thelen et al.'s and Piaget's accounts of the A-not-B error, we argue that, in contrast to Piaget, they do not explicitly address the issue of objectivity. We suggest that this omission is partly due to the fact that Thelen et al. and Piaget's accounts are pitched at different levels of explanation.

We argue that intelligible appeals to interlevel causes (top-down and bottom-up) can be understood, without remainder, as appeals to mechanistically mediated effects. Mechanistically mediated effects are hybrids of causal and constitutive relations, where the causal relations are exclusively intralevel. The idea of causation would have to stretch to the breaking point to accommodate interlevel causes. The notion of a mechanistically mediated effect is preferable because it can do all of the required work without appealing to mysterious interlevel causes. When (...) interlevel causes can be translated into mechanistically mediated effects, the posited relationship is intelligible and should raise no special philosophical objections. When they cannot, they are suspect. (shrink)

Accounts of mechanistic explanation have emphasized the importance of looking down—decomposing a mechanism into its parts and operations. Using research on visual processing as an exemplar, I illustrate how productive such research has been. But once multiple components of a mechanism have been identified, researchers also need to figure out how it is organized—they must look around and determine how to recompose the mechanism. Although researchers often begin by trying to recompose the mechanism in terms of sequential operations, they (...) frequently find that the components of a mechanism interact in complex ways involving positive and negative feedback and that the organization often exhibits highly interactive local networks linked by a few long-range connections (small-worlds organization) and power law distributions of connections. The mechanisms are themselves active systems that are perturbed by inputs but not set in motion by them. Researchers also need to look up —situate a mechanism in its context, which may be a larger mechanism that modulates its behavior. When looking down is combined with looking around and up, mechanistic research results in an integrated, multi-level perspective. (shrink)

I begin this chapter by outlining Mill's thinking about why justice is a problem for utilitarians. Next, I turn to Mill's own account of justice and explain its connection with rights, perfect duties, and harms. I then examine David Lyons' answer to the question of how Mill's account is meant to answer the Weak Objection from Justice. Lyons maintains that Mill's account of justice has both a conceptual side and a substantive side. The former provides an analysis of such (...) concepts as 'justice' and 'rights'. The latter, based on the Principle of Utility, provides an explanation of when these concepts apply. As a result, utilitarians can allow for circumstances in which actions are wrong because they are unjust, while also claiming that the standards of right and wrong (as well as justice and injustice) are determined by the Principle of Utility. However, the main thesis of this paper is that Lyons' interpretation is flawed. The distinction between the conceptual and the substantive levels of Mill's thinking does not hold up to scrutiny, and even if it did, it would not support Lyon's reading of Mill. It would instead support a debunking interpretation of justice, an interpretation recently explored by Roger Crisp. Such a debunking interpretation suggests a very different response to the Weak Objection from Justice, one that many, but not all, utilitarians will find unwelcome. (shrink)

In this article, I situate and reconstruct Sartre's rejections of subjective and objective idealism in order both to sketch his realism-all-the-way-down and to contrast it with Richard Rorty's pragmatic, anti-essentialist contextualism. The contrast with Rorty is important because his contextualism is one of the most prominent approaches within the relatively recent proliferation of antiessentialist views mobilized under the banners of pragmatism, hermeneutics, postmodernism, constructivism, etc. Although Rorty's contextualism is both compelling and comparable to Sartre's realism-all-the-way-down, I shall argue (...) that the latter does not throw out the baby that the former throws out with the bathwater. Realism-all-the-way-down is not compelled to throw out realism along with subjective and objective idealism, whereas contextualism must throw out the whole lot. If compelling intuitions recommend realism to us, and if Rorty's rejection of realism is unconvincing, there are good reasons to prefer Sartre's realism-all-the-way-down. (shrink)

Reductionism is a central issue in the philosophy of biology. One common objection to reduction is that molecular explanation requires reference to higher-level properties, which I refer to as the context objection. I respond to this objection by arguing that a well-articulated notion of a mechanism and what I term mechanism extension enables one to accommodate the context-dependence of biological processes within a reductive explanation. The existence of emergent features in the context could be raised as (...) an objection to the possibility of reduction via this strategy. I argue that this objection can be overcome by showing that there is no tenable argument for the existence of emergent properties that are not susceptible to a reductive explanation. (shrink)

As virtue ethics has developed into maturity, it has also met with a number of objections. This essay focuses on the self-centeredness objection: since virtue ethics recommends that we be concerned with our own virtues or virtuous characters, it is self-centered. In response, I first argue that, for Zhu Xi’s neo-Confucianism, the character that a virtuous person is concerned with consists largely in precisely those virtues that incline him or her to be concerned with the good of others. While (...) such an answer is also available to the Aristotelian virtue ethics, I argue that Zhu Xi’s neo-Confucianism can better respond to the objection on two deeper levels: (1) a virtuous person is not only concerned with others’ external well-being but also their virtuous characters, and (2) a virtuous person’s concern with others’ wellbeing, both internal and external, is neither self-indulgent nor self-effacing.

We argue that the pivotal role assigned by Northoff to the principle of top-down modulation in catatonia might successfully be applied to other symptoms of schizophrenia, for example, hallucinations. Second, we propose that Northoff's account would benefit from a more comprehensive analysis of the cognitive level of explanation. Finally, contrary to Northoff, we hypothesize that “top-down modulation” might play as important a role as “horizontal modulation” in affective-behavioral alterations.

A recent story in USA Today about the war in Afghanistan drew a direct parallel to the film Black Hawk Down : When the history of the war is written, the traumatic battle in the mountains around the Shah-e-Kot Valley will be remembered as a testament to heroism: A bloodied, outnumbered band of US servicemen held off a determined al-Qaeda force on frigid rocky terrain at least 8,000 feet above sea level. Call it Black Hawk Down in the (...) snow. (Jonathan Weisman, "Deadliest day for US", USA Today 3/6/02). Why would a reporter (Jonathan Weisman) interrupt his recitation of the facts of the battle, right near the start of his article, to suggest that readers should mimic the judgment of the film? Because the film seems to have a message, not only about history, but about the current US war on terrorism: support our troops, and don�t question a war�s intent or methods. (shrink)

Recent experimental work suggests that the concept of contextual fields should be generalized to allow the modulation of local information extraction by both external and internal context. The external context relates to the coherent information of the stimulus; the internal context refers to the parts of this information which are relevant for behavior. This dual interaction, present at every level of the hierarchy, requires a fundamental unit of processing more complex than a single neuron appears today. We argue that the (...) cortical column supplies the required mechanisms for a separate top-down and bottom-up processing and allows for interaction without destructive cross-talk. This flexibility might explain why the same basic architecture of a cortical column is used in the whole isocortex. (shrink)

Both Immanuel Kant and Paul Guyer have raised important concerns about the limitations of Lockean thought. Following Guyer, I will focus my attention on questions about the proper ambitions and likely achievements of inquiry into the natural/physical world. I will argue that there are at least two important respects, not discussed by Guyer, in which Locke’s account of natural philosophy is much more flexible and accommodating than may be immediately apparent. (And, I am inclined to think, one of these respects (...) represents a way in which Kant’s system is objectionably constrained, where Locke’s is in principle open.) On my interpretation, however, one crucial source of a too-limited vision of natural philosophy remains in Locke, where he is appropriately criticized by both Kant and Guyer. My method will be to begin with a distinction that Locke draws in the very first draft of the Essay, between what he calls “the sensible object” and, on the other hand, “the uncertain philosophical cause.” I believe that Locke’s notion of “sensible object,” as opposed to uncertain philosophical cause, retains a central place in his thought in the published Essay, despite the fact thateven though this contrast is never made explicitly there. Tracing the evolution of these two concepts in his thought will allow us to track and better understand his developing views about the relation between the project of the.. (shrink)

Dispositions are related to conditionals. Typically a fragile glass will break if struck with force. But possession of the disposition does not entail the corresponding simple (subjunctive or counterfactual) conditional. The phenomena of finks and antidotes show that an object may possess the disposition without the conditional being true. Finks and antidotes may be thought of as exceptions to the straightforward relation between disposition and conditional. The existence of these phenomena are easy to demonstrate at the macro-level. But do they (...) exist at the fundamental level also? While fundamental finkish dispositions may be excluded fairly straightforwardly, the existence of fundamental antidotes is more open. Nonetheless I conclude that the phenomenon is likely to be less widespread than at the macro level and that fundamental antidotes may be eliminable. According to the dispositional essentialist, the laws of nature can be explained by taking natural properties to be essentially dispositional. This account can be extended to show that the existence of finks and antidotes explains ceteris paribus laws. Consequently the existence or otherwise of fundamental finks and antidotes sheds some light on the question of whether fundamental laws may also be ceteris paribus laws. (shrink)

Abstract The debate about the ethics of uninhabited aerial vehicles (UAVs) is failing to keep pace with the rise of the technology. Therefore, all the key players, including ethicists, lawyers, and roboticists, are keen to offer their views on the use of these drone aircraft. Some are opposed to their use, citing a range of ethical, legal and operational issues, while others argue for their ethically mandated use. B.J. Strawser fits into this latter category. He develops a principle of ?unnecessary (...) risk?, from which he argues that we have an ethical obligation to employ UAVs if we can do so without incurring a loss of capability. Strawser defends his argument against a number of potential objections, most questionably, the argument that the use of distance weaponry such as drones, against another state without distance weaponry, crosses some moral threshold that makes the combat immoral. Utilising Jeff McMahan's work on the inequality of combatants, Strawser essentially argues that there are no grounds for a ?fair fight?. However, this paper will argue that it is not so easy to overturn the doctrine of the moral equality of combatants, nor dismiss the problem with asymmetry. It will demonstrate that if the asymmetry reaches a certain level, the justification for resorting to war may be removed and some sort of policing action may remain the only option. (shrink)

Utilitarians are attracted to the idea that an act is morally right iff it leads to the best outcome. But critics have pointed out that in many cases we cannot determine which of our alternatives in fact would lead to the best outcome. So we can’t use the classic principle to determine what we should do. It’s not “practical”; it’s not “action-guiding”. Some take this to be a serious objection to utilitarianism, since they think a moral theory ought to (...) be practical and action-guiding. In response, some utilitarians propose to modify utilitarianism by replacing talk of actual utility with talk of expected utility. Others propose to leave the original utilitarian principle in place, but to combine it with a decision procedure involving expected utility. What all these philosophers have in common is this: they move toward expected utility in order to defend utilitarianism against the impracticality objection. My aim in this paper is to cast doubt on this way of replying to the objection. My central claim is that if utilitarians are worried about the impracticality objection, they should not turn to expected utility utilitarianism. That theory does not provide the basis for a cogent reply to the objection. (shrink)

The text surveys the development of the debate between Zahavi and Brough/Sokolowski regarding Husserl’s account of inner time-consciousness. The main arguments on both sides are reconsidered, and a compromise is proposed.

In this paper, we show that presentism?the view that the way things are is the way things presently are?is not undermined by the objection from being-supervenience. This objection claims, roughly, that presentism has trouble accounting for the truth-value of past-tense claims. Our demonstration amounts to the articulation and defence of a novel version of presentism. This is brute past presentism, according to which the truth-value of past-tense claims is determined by the past understood as a fundamental aspect of (...) reality different from things and how things are.

Attributer contextualists maintain that the verb 'knows' is context-sensitive in the sense that the truth conditions of a sentence of the form "S knows that p" can be dependent upon the ascriber's context. One natural objection against attributer contextualism is that it confuses the impropriety of certain assertions which ascribe knowledge to agents with the falsity of those assertions. In an influential article, Keith DeRose has defended attributer contextualism against this charge by proposing constraints on what he calls "warranted (...) assertibility manoeuvres" of this sort. This paper argues that, contra DeRose, the warranted assertibility manoeuvre directed at attributer contextualism is able to meet the constraints that DeRose lays down. (shrink)

This article argues that practitioners have a professional ethical obligation to dispense emergency contraception, even given conscientious objection to this treatment. This recent controversy affects all medical professionals, including physicians as well as pharmacists. This article begins by analyzing the option of referring the patient to another willing provider. Objecting professionals may conscientiously refuse because they consider emergency contraception to be equivalent to abortion or because they believe contraception itself is immoral. This article critically evaluates these reasons and concludes (...) that they do not successfully support conscientious objection in this context. Contrary to the views of other thinkers, it is not possible to easily strike a respectful balance between the interests of objecting providers and patients in this case. As medical professionals, providers have an ethical duty to inform women of this option and provide emergency contraception when this treatment is requested. (shrink)

What is the relation between a clay statue andthe lump of clay from which it is made? According to the defender of the standardaccount, the statue and the lump are distinct,enduring objects that share the same spatiallocation whenever they both exist. Suchobjects also seem to share the samemicrophysical structure whenever they bothexist. This leads to the standard objection tothe standard account: if the statue and thelump of clay have the same microphysicalstructure whenever they both exist, how canthey differ in (...) their de re temporalproperties, de re modal properties and soon? In this paper I develop amereological answer to this question – thestatue and the lump differ with respect totheir parts and this explains theirdifference with respect to de re temporalproperties, de re modal properties andthe like.

When it is suggested that the fine-tuning of the universe for life provides evidence for a cosmic designer, the multiple-universe hypothesis is often presented as an alternative. Some philosophers object that the multiple-universe hypothesis fails to explain why ’this’ universe is fine-tuned for life. We suggest the "this universe" objection is no better than the "this planet" objection. We also fault proponents of the "this universe" objection for presupposing that we could not have existed in any other (...) universe and that the values of the free parameters of the universe could have been different. Lastly, we reflect on why fine-tuning for life needs explaining. (shrink)

According to Field’s influential incompleteness objection, Tarski’s semantic theory of truth is unsatisfactory since the definition that forms its basis is incomplete in two distinct senses: (1) it is physicalistically inadequate, and for this reason, (2) it is conceptually deficient. In this paper, I defend the semantic theory of truth against the incompleteness objection by conceding (1) but rejecting (2). After arguing that Davidson and McDowell’s reply to the incompleteness objection fails to pass muster, I argue that, (...) within the constraints of a non-reductive physicalism and a holism concerning the concepts of truth, reference and meaning, conceding Field’s physicalistic inadequacy conclusion while rejecting his conceptual deficiency conclusion is a promising reply to the incompleteness objection.

A common objection raised against naturalism is that anaturalized epistemology cannot account for the essential normative character of epistemology. Following an analysis of different ways in which this charge could be understood, it will be argued that either epistemology is not normative in the relevant sense, or if it is, then in a way which a naturalized epistemology can account for with an instrumental and hypothetical model of normativity. Naturalism is here captured by the two doctrines of empiricism and (...) gradualism. Epistemology is a descriptive discipline about what knowledge is and under what conditions a knowledge-claim is justified. However, we can choose to adopt a standard of justification and by doing so be evaluated by it. In this sense our epistemic practices have a normative character, but this is a form of normativity a naturalized epistemology can make room for. The normativity objection thus fails. However, in the course of this discussion, as yet another attempt to clarify the normativity objection, such a naturalistic model will be contrasted with Donald Davidson's theory of interpretation. Even though this comparison will not improve upon the negative verdict upon the original objection, it will be argued that naturalism cannot accept Davidson's theory since it contains at least one constitutive principle – the principle of charity – whose epistemic status is incompatible with the naturalistic doctrine of gradualism. So, if this principle has this role, then epistemology cannot be naturalized. (shrink)

According to luck egalitarianism, inequalities are justified if and only if they arise from choices for which it is reasonable to hold agents responsible. This position has been criticised for its purported harshness in responding to the plight of individuals who, through their own choices, end up destitute. This paper aims to assess the Harshness Objection. I put forward a version of the objection that has been qualified to take into account some of the more subtle elements of (...) the luck egalitarian approach. Revising the objection in this way suggests that the Harshness Objection has been overstated by its proponents: because luck egalitarians are sensitive to the influence of unequal brute luck on individuals’ choices, it is unlikely that there will be any real world cases in which the luck egalitarian would not have to provide at least partial compensation. However, the Harshness Objection still poses problems for the luck egalitarian. First, it is not clear that partial compensation will be sufficient to avoid catastrophic outcomes. Second, the Harshness Objection raises a theoretical problem in that a consistent luck egalitarian will have to regard it as unjust if any assistance is provided to the victim of pure option luck, even if such assistance could be provided at no cost. I consider three strategies the luck egalitarian could pursue to accommodate these concerns and conclude that none of these strategies can be maintained without either violating basic luck egalitarian principles or infringing upon individual liberty.

The Molinist doctrine that God has middle knowledge requires that God knows the truth-values of counterfactuals of freedom, propositions about what free agents would do in hypothetical circumstances. A well-known objection to middle knowledge, the grounding objection, contends that counterfactuals of freedom have no truth-value because there is no fact to the matter as to what an agent with libertarian freedom would do in counterfactual circumstances. Molinists, however, have offered responses to the grounding objection that they believe (...) are adequate for maintaining the coherence of middle knowledge. I argue that these responses to the grounding objection are not adequate, and that what I call the ‘generic grounding objection’ still poses a serious challenge to middle knowledge. (shrink)

“Perhaps the most common objection to consequentialism is this: it is impossible to know the future…This means that you will never be absolutely certain as to what all the consequences of your act will be…there may be long term bad effects from your act, side effects that were unforeseen and indeed unforeseeable…So how can we tell which act will lead to the best results overall – counting all the results? This seems to mean that consequentialism will be unusable as (...) a moral guide to action. All the evidence available at the time of acting may have pointed to the conclusion that a given act was the right act to perform – and yet it may still turn out that what you did had horrible results, and so in fact was morally wrong. Indeed, if will never be possible to say for sure that any given act was right or wrong, since any event can continue to have further unseen effects down through history. Yet if it is impossible to tell whether any act is morally right or wrong, how can consequentialism possibly be a correct moral theory?”. (shrink)

It is often thought that Blackburn and Boghossian have provided an effective reply to the finiteness objection to dispositional theories of meaning, presented by Kripke's Wittgenstein. In this paper I distinguish two possible readings of the sceptical demand for meaning-constitutive facts. The demand can be formulated in one of two ways: an A-question or a B-question. Any theory of meaning will give one of these explanatory priority over the other. I will then argue that the standard reply only works (...) if B-questions are seen as prior, while the dominant dispositionalist theories of meaning see A-questions as prior. (shrink)

Preference utilitarianism is widely considered a significant advance on classical utilitarianism when it comes to explaining why it is wrong to kill people. This paper focuses attention on the nature of the preference utilitarian 'direct' objection to killing a person and on the related claim that a person's preferences are non-replaceable. I argue that the preference utilitarian case against killing people is overstated and overrated. My concluding remarks indicate the relevance of this discussion to deeper issues in normative moral (...) theory. (shrink)

Positions on the ethics of human enhancement technologies can be (crudely) characterized as ranging from transhumanism to bioconservatism. Transhumanists believe that human enhancement technologies should be made widely available, that individuals should have broad discretion over which of these technologies to apply to themselves, and that parents should normally have the right to choose enhancements for their children-to-be. Bioconservatives (whose ranks include such diverse writers as Leon Kass, Francis Fukuyama, George Annas, Wesley Smith, Jeremy Rifkin, and Bill McKibben) are generally (...) opposed to the use of technology to modify human nature. A central idea in bioconservativism is that human enhancement technologies will undermine our human dignity. To forestall a slide down the slippery slope towards an ultimately debased ‘posthuman’ state, bioconservatives often argue for broad bans on otherwise promising human enhancements. This paper distinguishes two common fears about the posthuman and argues for the importance of a concept of dignity that is inclusive enough to also apply to many possible posthuman beings. Recognizing the possibility of posthuman dignity undercuts an important objection against human enhancement and removes a distortive double standard from our field of moral vision. (shrink)

Many philosophers accept a ‘layered’ world‐view according to which the facts about the higher ontological levels supervene on the facts about the lower levels. Advocates of such views often have in mind a version of atomism, according to which there is a fundamental level of indivisible objects known as simples or atoms upon whose spatiotemporal locations and intrinsic properties everything at the higher levels supervenes.1 Some, however, accept the possibility of ‘gunk’ worlds in which there are parts ‘all the way (...) down’ such that there are no simples and insofar as composite objects exist these are composed of smaller objects which in turn are composed of smaller objects, and so on. It may nonetheless still be claimed that the facts about each ontological level supervene on the facts about the lower levels. (shrink)

The anti-reductionist who wants to preserve the causal efficacy of mental phenomena faces several problems in regard to mental causation, i.e. mental events which cause other events, arising from her desire to accept the ontological primacy of the physical and at the same time save the special character of the mental. Psychology tries to persuade us of the former, appealing thereby to the results of experiments carried out in neurology; the latter is, however, deeply rooted in our everyday actions and (...) beliefs and despite the constant opposition of science still very much alive. Difficulties, however, arise from a combination of two claims that are widely accepted in philosophy of mind, namely, physical monism and mental realism, the acceptance of which leads us to the greatest problem of mental causation: the problem of causal exclusion. Since physical causes alone are always sufficient for physical effects mental properties are excluded from causal explanations of our behaviour, which makes them “epiphenomenal”. The article introduces Van Gulick’s solution to the exclusion problem which tries to prove that physical properties, in contrast to mental properties, do not have as much of a privileged status with respect to event causation as usually ascribed. Therefore, it makes no sense to say that physical properties are causally relevant whereas mental properties are not. This is followed by my objection to his argument for levelling mental and physical properties with respect to causation of events. I try to show that Van Gulick’s argument rests on a premise that no serious physicalist can accept. (shrink)

In the worlds of philosophy, linguistics, and communications theory, a view has developed which understands conscious experience as experience which is 'reflected' back upon itself through language. This indicates that the consciousness we experience is possible only because we have culturally invented language and subsequently evolved to accommodate it. This accords with the conclusions of Daniel Dennett (1991), but the 'hermeneutic objection' would go further and deny that the objective sciences themselves have escaped the hermeneutic circle. -/- The consciousness (...) we humans experience is developed only within the context of crossing the 'symbolic threshold' (Percy 1975; Deacon 1997) and one of the earliest and most important symbols we acquire is that of the self, or 'the subject of experience'. It is only when we achieve self-awareness that the world, as such, comes to exist for us as an object (which contains categories and sub-categories of objects). Any consciousness imputed to prelinguistic stages of development is based on projection and guesswork, since we can know nothing directly of it. It can be said that any experience which does not separate an inner subject from an outer world is probably a continuum of sensation in which environmental stimulus and instinctive response are experienced as a unity; it may be 'lived experience' but it is experience 'lived' non-consciously. -/- Speech requires assertion and by learning to speak we find ourselves asserting, in essence, our selves into the world. The narrative form of language allows us to develop life stories, self-knowledge, and, most important, narrative memory coincident with narrative time. All this is made possible with the intersubjective 'net' of language which allows us to know ourselves by first identifying with the viewpoint of others; and, later, such allows us to identify with other minds as we anticipate their reception our communication. These three, assertion, narrative, and intersubjectivity are the essence of what language is and are the keystones that make culture possible outside of nature. (shrink)

The ‘Responsibility Objection’ to Judith Thomson's famous argument for the permissibility of abortion challenges the relevance of her ‘Violinist Analogy’ to certain types of voluntary unwanted pregnancy, on the grounds that those pregnancies, even though they may be unwanted, are pregnancies for which the woman can be plausibly held responsible. This article considers the force of a number of recent objections to the Responsibility Objection, advanced by Harry Silverstein, David Boonin, and Jeff McMahan, and judges them to be (...) unpersuasive. It is concluded that, in the absence of further considerations, the Responsibility Objection carries force. (shrink)

The worst possible way to resolve this issue is to leave it up to individual choice. There is no known social good coming from the conquest of death (Bailey, 1999). - Daniel Callahan Dramatically extending the human lifespan seems increasingly possible. Many bioethicists object that life-extension will have Malthusian consequences as new Methuselahs accumulate, generation by generation. I argue for a Life-Years Response to the Malthusian Objection. If even a minority of each generation chooses life-extension, denying it to them (...) deprives them of many years of extra life, and their total extra life-years are likely to exceed the total life-years of a majority who do not want life-extension. This is a greater harm to those who want extended life than the Malthusian harms to those who refuse extended life, both because losing an extra year of life is worse than enduring a year of Malthusian conditions, and because the would-be Methuselahs have more life-years at stake. Therefore, even if life-extension seems likely to cause severe overcrowding and resource shortages, that threat is not sufficient to justify society in restricting the development or availability of life-extension.

David Lewis has long defended an analysis of counterfactuals in terms of comparative similarity of possible worlds. The purpose of this paper is to reevaluate Lewis’s response to one of the oldest and most familiar objections to this proposal, the future similarity objection.

One of the central problems afflicting reductionism in the epistemology of testimony is the apparent fact that infants and small children are not cognitively capable of having the inductively based positive reasons required by this view. Since non-reductionism does not impose a requirement of this sort, it is thought to avoid this problem and is therefore taken to have a significant advantage over reductionism. In this paper, however, I argue that if this objection undermines reductionism, then a variant of (...) it similarly undermines non-reductionism. Thus, considerations about the cognitive capacities of infants and small children do not effectively discriminate between these two competing theories of testimonial justification. (shrink)

In this paper I examine the most common objection to strict product liability: that it is unfair to manufacturers. Critics have maintained that it is unfair because it allows manufacturers to be held liable even when they have not been negligent, and are not morally blameworthy or at fault. In response to this objection, I argue 1) that there are in fact cases in which it is at least somewhat unfair to manufacturers to impose compensation requirements upon them (...) in accordance with the strict product liability doctrine, but 2) that there is also a class of cases in which it is fair to manufacturers to hold them responsible for compensating injured product users, as strict product liability requires, even though they have not been negligent and are not morally blameworthy or at fault. My analysis of the fairness issue provides a basis for some concluding remarks about the defensibility of the strict product liability doctrine. (shrink)

Scientific realists often appeal to some version of the conjunction objection to argue that scientific instrumentalism fails to do justice to the full empirical import of scientific theories.

In his 'The Disorder of Things' John Dupré presents an objection to reductionism which I call the 'anti-essentialist objection': it is that reductionism requires essentialism, and essentialism is false. I unpack the objection and assess its cogency. Once the objection is clearly in view, it is likely to appeal to those who think conceptual analysis a bankrupt project. I offer on behalf of the reductionist two strategies for responding, one which seeks to rehabilitate conceptual analysis and (...) one (more concessive) which avoids commitment to any such analysis.

Whether refusal is an act of civil disobedience meant to challenge the state politically as a form of protest, or an action which reflects a deep moral objection to the policies of the state, selective conscientious objection presents the state and its citizens with a number of difficult legal and moral challenges. Appeals to authority outside of the state, whether religious or secular, influence both citizenship and the behavior of the government itself. As Israel raises funds to defend (...) IDF officers from charges of human rights violations in the United Kingdom, it may find itself in need of a better defense against those citizens hesitant to be placed in harm's way, militarily and legally. At some point in the future it may find itself unable to field soldiers for whom service in the Occupied Territories is prohibited by inviolable secular or religious law. And for those who will continue to argue that they cannot abide service in an army of occupation, an expression sounded in 1968 by Yeshayahu Leibowitz, the moral crisis of an individual conscience rent between obligations to the state and obligations to self, will linger along with the pain of a conscience nurtured and then rejected by this democratic society.

The Doctrine of Temporal Parts (sometimes abbreviated herein as 'DTP') asserts that, for each portion (including infinitely small portions) of the smallest period of time during which a material object exists, there is an object-a temporal part of the material object in question-which exists at that and at no other time. In "Things Change," Mark Heller offers an argument for DTP, and responds to a objection, the "No-Change" objection, to that doctrine.2 My goal in this paper is to (...) undermine both Heller's argument in favor of DTP and his response to that criticism.

Eliminative materialism is the position that common?sense psychology is false and that beliefs and desires, like witches and demons, do not exist. One of the most popular criticisms of this view is that it is self?refuting or, in some sense, incoherent.

From time to time, the idea that enduring things can change has been challenged. The latest challenge has come in the form of what David Lewis has called a “decisive objection”, which claims to deduce a contradiction from the idea that enduring things change with respect to their temporary intrinsics, when that idea is combined with eternalism. It is my aim in this paper to explain why I think that no argument has yet appeared that deduces a contradiction from (...) a combination of eternalism and the idea that enduring things change with respect to their temporary intrinsics, except ones that do so by committing scope fallacies.

Can all goods or bads be broken down into smaller and smaller pieces? Can all goods or bads be added together with some other good or bad to get a larger amount? Further, how does moral significance track the disaggregation and the aggregation of moral goods and bads? In Part 1, I examine the limits placed on aggregation by moderate deontological moral theories. This paper focuses in particular on the work of Judith Thomson and T.M. Scanlon as well (...) as on some of my own past work on the question of aggregation in the context of overriding rights. In Part 2, I examine consequentialist criticism that harms and benefits can be broken down into smaller pieces than the deontological theory allows and the argument that the moderate deontological view is too permissive since it allows aggregation of benefits within a single person's life. In Part 3 I suggest how a moderate deontological moral theory might respond to the criticisms. I cast my answer in terms of the existence of lumpy goods and bads. I argue that consequentialist critics of deontology are wrong to insist that all goods and bads can be disaggregated and aggregated at will. Instead, I offer the suggestion that most, or many, goods and bads come in morally significant lumps. That said, it will not always be obvious what those lumps are. Determining the texture of moral value is a substantive project in normative ethics. All I have hoped to do in this paper is suggest that two standard positions on how to group moral value are mistaken and give hope that we need not adopt one of the two. Part 4 of the paper responds to an objection and sets the stage for further work in value theory. (shrink)

: I argue that there is an important analogy between sex selection and selective abortion of fetuses diagnosed with Down syndrome. There are surprising parallels between the social construction of Down syndrome as a disability and the deeply entrenched institutionalization of sexual difference in many societies. Prevailing concepts of gender and mental retardation exert a powerful influence in constructing the sexual identities and life plans of people with Down syndrome, and also affect their families' lives.

This paper has two main purposes: first to compare Wittgenstein's views to the more traditional views in the philosophy of mathematics; second, to provide a general outline for a Wittgensteinian reply to two objections against Wittgenstein's account of mathematics: the objectivity objection and the consistency objections, respectively. Two fundamental thesmes of Wittgenstein's account of mathematics title the first two sections: mathematical propositions are rules and not descritpions and mathematics is employed within a form of life. Under each heading, I (...) examine Wittgenstein's rejection of alternative views. My aim is to make clear the differences and to suggest some similarities. As will become clear, Wittgenstein often rejects opposing views for the same or similar reasons. This comparison will provide the necessary background for better understanding Wittgenstein's philosophy of mathematics, for appreciating its many unappreciated advantages and, finally, for defending a conventionalist account of mathematics.

We offer a new argument for the claim that there can be non-degenerate objective chance (“true randomness”) in a deterministic world. Using a formal model of the relationship between different levels of description of a system, we show how objective chance at a higher level can coexist with its absence at a lower level. Unlike previous arguments for the level-specificity of chance, our argument shows, in a precise sense, that higher-level chance does not collapse into epistemic probability, despite higher-level properties (...) supervening on lower-level ones. We show that the distinction between objective chance and epistemic probability can be drawn, and operationalized, at every level of description. There is, therefore, not a single distinction between objective and epistemic probability, but a family of such distinctions. (shrink)

Several recent publications have suggested that hermeneutics, the method of literary criticism, might prove to be useful in medicine. In this essay I consider this thesis with particular attention to the claim that medicine is hermeneutics all the way down.

A brief discussion ofphronesis and of the possible texts of medicine concludes the article. (shrink)

One common objection to fetal tissue transplantation (FTT) is that, if it were to become a standard form of treatment, it would encourage or entrench the practice of abortion. This claim is at least factually plausible, although it cannot be definitively established. However, even if true, it does not constitute a compelling ethical argument against FTT. The harm allegedly brought about by FTT, when assessed by widely accepted non-consequentialist criteria, has limited moral significance. Even if FTT would cause more (...) abortions to be performed, and abortion is taken to be a serious moral wrong, this is not sufficient in itself to make FTT wrong. (shrink)

Many philosophers, both past and present, object to materialism not from any romantic anti-scientific bent, but from sheer inability to understand the thesis. It seems utterly inconceivable to some that qualia should exist in a world which is entirely material. This paper investigates the grain objection, a much neglected argument which purports to prove that sensations could not be brain events. Three versions are examined in great detail. The plausibility of the first version is shown to depend crucially on (...) whether one holds a direct or non-direct theory of perception. Only on the latter is this version plausible. An analysis of the second "semantic" version concludes that a materialist description and explanation of the world should not be expected to transparently convey all that would be of interest or importance to human beings. The final version explicitly makes use of Grover Maxwell's non-direct perceptual theory of structural realism. Although a confusion is charged to Maxwell between phenomenal and objective properties, the critical difficulty for the grain objection is its failure to characterize "structure" from a non-percipient point of view. As the grain objection is ultimately found wanting, the real difficulty for materialism crystallizes as its irreconciliability with the mere existence of sentience, which seems to force some sort of emergence upon us.

Dunn and Hellman's objection to Popper and Miller's alleged disproof of inductive probability is considered and rejected. Dunn and Hellman base their objection on a decomposition of the incremental support P(h/e)-P(h) of h by e dual to that of Popper and Miller, and argue, dually to Popper and Miller, to a conclusion contrary to the latters' that all support is deductive in character. I contend that Dunn and Hellman's dualizing argument fails because the elements of their decomposition are (...) not supports of parts of h.

In a series of closely connected papers, Rosenthal has defended what has come to be known as “the higher-order thought theory of state-consciousness.” According to this theory, a mental state which one instantiates is conscious if and only if one is conscious of being in it in some relevant way, and one’s being conscious of being in the state which is conscious consists in one’s having a contemporaneous thought to the effect that one is in that state. The main aim (...) of this paper is to disarm a Searle-style objection to Rosenthal’s account of state-consciousness, one that takes mentality, in particular intentionality, to presuppose state-consciousness. It is argued that the Searlean attempt to convict Rosenthal’s hypothesis of circularity fails, because the postulation of what Searle called “subjective ontology,” as well as the requirement that there be an uncancelable connection between mode of representation and state-consciousness, is unreasonable. While defending Rosenthal against Searle, this paper also aims to develop a fresh objection to the higher-order thought conception of state-consciousness. (shrink)

Considerations of virtue and character appear from time to time in the agricultural biotechnology literature. Critics of the technologies often suggest that they are contrary to some virtue (usually humility) or do not fit with the image of ourselves and the human place in the world that we ought to embrace. In this article, I consider the aretaic or virtue-based objection that to engage in agricultural biotechnology is to exhibit arrogance, hubris, and disaffection. In section one, I discuss Gary (...) Comstock's treatment of this objection. In section two, I provide an alternative interpretation of the objection that more accurately reflects the concerns of those who offer the criticism than does Comstock's standard interpretation. In sections three and four, I assess the objection. I argue that despite its merits, the objection does not justify global opposition to agricultural biotechnology. Instead, it favors a limited endorsement position not unlike the one defended by Comstock. (shrink)

Eigenfeatures are created by the principal component approach (PCA) used on objects described by a low-level code (i.e., pixels, Gabor jets). We suggest that eigenfeatures act like the flexible features described by Schyns et al. They are particularly suited for face processing and give rise to class-specific effects such as the other-race effect. The PCA approach can be modified to accommodate top-down constraints.

The holistic representation of objects as coordinates in a psychological space should be supplemented with decompositional processes that break objects down into components. There is strong psychological evidence for object decomposition, and structured representations are also needed because of their computational efficiency. Structured and unstructured representations can be unified by a process that extracts regularities at multiple levels of an object.

The processes whereby our brains continue to learn about a changing world in a stable fashion throughout life are proposed to lead to conscious experiences. These processes include the learning of top-down expectations, the matching of these expectations against bottom-up data, the focusing of attention upon the expected clusters of information, and the development of resonant states between bottom-up and top-down processes as they reach an attentive consensus between what is expected and what is there in the outside (...) world. It is suggested that all conscious states in the brain are resonant states and that these resonant states trigger learning of sensory and cognitive representations. The models which summarize these concepts are therefore called Adaptive Resonance Theory, or ART, models. Psychophysical and neurobiological data in support of ART are presented from early vision, visual object recognition, auditory streaming, variable-rate speech perception, somatosensory perception, and cognitive-emotional interactions, among others. It is noted that ART mechanisms seem to be operative at all levels of the visual system, and it is proposed how these mechanisms are realized by known laminar circuits of visual cortex. It is predicted that the same circuit realization of ART mechanisms will be found in the laminar circuits of all sensory and cognitive neocortex. Concepts and data are summarized concerning how some visual percepts may be visibly, or modally, perceived, whereas amodal percepts may be consciously recognized even though they are perceptually invisible. It is also suggested that sensory and cognitive processing in the What processing stream of the brain obey top-down matching and learning laws that are often complementary to those used for spatial and motor processing in the brain's Where processing stream. This enables our sensory and cognitive representations to maintain their stability as we learn more about the world, while allowing spatial and motor representations to forget learned maps and gains that are no longer appropriate as our bodies develop and grow from infanthood to adulthood. Procedural memories are proposed to be unconscious because the inhibitory matching process that supports these spatial and motor processes cannot lead to resonance. (shrink)

It has long ben recognised that there are referential uses of definite descriptions. It is not as widely recognised that there are atttributives uses of idexicals and other such paradigmatically singular terms. I offer an account of the referential/attributive distinction which is intended to give a unified treatment of both sorts of cases. I argue that the best way to account for the referential/attributive distinction is to treat is as semantically underdetermined which sort of propositions is expressed in a context. (...) In certain contexts the proposition expressed will be a descriptive one, and in others it will be an object-dependent one. I appeal to Sperer and Wilson's (1986) idea that the recovery of the content of an utterance involves pragmatic processes of enrichment of a representation of the logical form of utterance. According to the account I offer, the first-level descriptive meaning associated with an expression (whether this is an indexical or a definite description) is pragmatically enriched and then used either to track an individual in the context, or is taken to lay down a condition of satisfaction for an individual. The proposition that the listener takes the speaker to have expressed is recovered on the basis of considerations of relevance and contextually available information about the speaker's directive intentions. Although my account has affinities with those of Recanati (1993) and Nunberg (1993), it also differs from theirs in crucial ways. Each of these authors sees asymmetries where I see none. I give reasons for preferring my symmetrical account. (shrink)

Cognitive neuropsychology is that branch of cognitive psychology that investi- gates people with acquired or developmental disorders of cognition. The aim is to learn more about how cognitive systems normally operate or about how they are normally acquired by studying selective patterns of cognitive break- down after brain damage or selective dif?culties in acquiring particular cogni- tive abilities. In the early days of modern cognitive neuropsychology, research focused on rather basic cognitive abilities such as speech comprehension or production at (...) the single-word level, reading and spelling, object and face recognition, and short-term memory. More recently the cognitive-neuro- psychological approach has been applied to the study of rather more complex domains of cognition such as belief ?xation (e.g. Coltheart and Davies, 2000; Langdon and Coltheart, 2000) and pragmatic aspects of communication (e.g. McDonald and Van Sommers, 1993). Our paper concerns the investigation of pragmatic disorders in one clinical group in which such disorders are common, patients with schizophrenia, and what the study of such people can tell us about the normal processes of communication.

After a review of his revisions of Husserl's methodology, Cairns's new version of the procedure of Abbauor unbuilding is followed from the Objective world down to the primordial world and then from there down to the phantom world within which sensa fields can be analyzed. Then the abstractive epochēs by which lower strata were reached are successively relaxed in the Aufbau or upbuilding procedure and, most interestingly, the sense “psychophysical thing” originally constituted within primordial automaticity is found to (...) be transferred automatically and with presumptive certainty to everything in the Objective world. Any differences between “animate” and “inanimate” things are only constituted at a higher level and pertain then to culture and not nature. (shrink)
