1 Evidence-based policy requires researchers to provide the answers to ecological questions that are of interest to policy makers. To find out what those questions are in the UK, representatives from 28 organizations involved in policy, together with scientists from 10 academic institutions, were asked to generate a list of questions from their organizations. 2 During a 2-day workshop the initial list of 1003 questions generated from consulting at least 654 policy makers and academics was used as a basis for (...) generating a short list of 100 questions of significant policy relevance. Short-listing was decided on the basis of the preferences of the representatives from the policy-led organizations. 3 The areas covered included most major issues of environmental concern in the UK, including agriculture, marine fisheries, climate change, ecosystem function and land management. 4 The most striking outcome was the preference for general questions rather than narrow ones. The reason is that policy is driven by broad issues rather than specific ones. In contrast, scientists are frequently best equipped to answer specific questions. This means that it may be necessary to extract the underpinning specific question before researchers can proceed. 5 Synthesis and applications. Greater communication between policy makers and scientists is required in order to ensure that applied ecologists are dealing with issues in a way that can feed into policy. It is particularly important that applied ecologists emphasize the generic value of their work wherever possible. (shrink)

A version of relationism that takes spatiotemporal structures—spatial geometry and a standard of inertia—to supervene on the history of relations between bodies is described and defended. The account is used to explain how the relationist should construe models of Newtonian mechanics in which absolute acceleration manifestly does not supervene on the relations; Ptolemaic and Copernican models for example. The account introduces a new way in which a Lewis-style ‘best system’ might capture regularities in a broadly Humean world; a defence is (...) given against a charge of indeterminism that applies to any such approach to laws.

This paper argues that the dirty hands literature has overlooked a crucial distinction in neglecting to discuss explicitly the issue of, what I call, symmetry. This is the question of whether, once we are confronted with a dirty hands situation, we could emerge with our hands clean depending on the action we choose. A position that argues that we can keep our hands clean I call “asymmetrical” and one that says that we will get our hands dirty no matter what (...) we do I call “symmetrical”. Not acknowledging this distinction is a problem because, firstly, it adds to the existing confusions about how best to define what dirty hands are. Secondly, it prevents the concept of dirty hands from being applied properly to other contexts such as, for example, the responsibility and accountability of politicians. I argue that we have good reason to favour a symmetrical understanding because it gives a more convincing account of what makes an action dirty and because it more accurately captures our complex moral decision-making when faced with dirty hands situations. The paper concludes by outlining possible implications that the distinction between the symmetry view and the asymmetry view has on wider debates surrounding the problem of dirty hands. (shrink)

What are the groundrules in the philosophy of art? What criteria of adequacy should we use for assessing theories of art?

Does human enhancement threaten our dignity as some prominent commentators have asserted? Or could our dignity perhaps be technologically enhanced? After disentangling several different concepts of dignity, this essay focuses on the idea of dignity as a quality, a kind of excellence admitting of degrees and applicable to entities both within and without the human realm. I argue that dignity in this sense interacts with enhancement in complex ways which bring to light some fundamental issues in value theory, and that (...) the effects of any given enhancement must be evaluated in its appropriate empirical context. Yet it is possible that through enhancement we could become better able to appreciate and secure many forms of dignity that are overlooked or missing under current conditions. I also suggest that in a posthuman world, dignity as a quality could grow in importance as an organizing moral/aesthetic idea. (shrink)

I argue that Hanslick was right to think that music should not be understood in terms of emotion. In particular, it is not essential to music to possess emotions, arouse emotions, express emotions, or represent emotions. All such theories are misguided.

Beauty is an important part of our lives. Ugliness too. It is no surprise then that philosophers since antiquity have been interested in our experiences of and judgments about beauty and ugliness. They have tried to understand the nature of these experiences and judgments, and they have also wanted to know whether these experiences and judgments were legitimate. Both these projects took a sharpened form in the twentieth century, when this part of our lives came under a sustained attack in (...) both European and American intellectual circles. Much of the discourse about beauty since the Eighteenth century had deployed a notion of the ‘aesthetic’, and so that notion in particular came in for criticism. This disdain for the aesthetic may have roots in a broader cultural Puritanism, which fears the connection between the aesthetic and pleasure. Even to suggest, in the recent climate, that an artwork might be good because it is pleasurable, as opposed to cognitively, morally or politically beneficial, is to court derision. The twentieth century has not been kind to the notions of beauty or the aesthetic. Nevertheless, some thinkers — philosophers, as well as others in the study of particular arts — have persisted in thinking about beauty and the aesthetic in a traditional way. In the first part of this essay, I look at the particular rich account of judgments of beauty given to us by Immanuel Kant. The notion of a ‘judgment of taste’ is central to Kant's account and also to virtually everyone working in traditional aesthetics; so I begin by examining Kant's characterisation of the judgment of taste. In the second part, I look at the issues that twentieth century thinkers have raised. I end by drawing on Kant's accout of the judgement of taste to consider whether the notion of the aesthetic is viable. (shrink)

I defend moderate formalism about the aesthetics of nature. I argue that anti-formalists cannot account for the incongruousness of much natural beauty. This shows that some natural beauty is not kind-dependent. I then tackle several anti-formalist arguments that can be found in the writings of Ronald Hepburn, Allen Carlson, and Malcolm Budd.

Anthony Brueckner, in a recent article, proffers ‘a new way of thinking about Bostrom's Simulation Argument’ . His comments, however, misconstrue the argument; and some words of explanation are in order.The Simulation Argument purports to show, given some plausible assumptions, that at least one of three propositions is true . Roughly stated, these propositions are: almost all civilizations at our current level of development go extinct before reaching technological maturity; there is a strong convergence among technologically mature civilizations such that (...) almost all of them lose interest in creating ancestor-simulations; almost all people with our sorts of experiences live in computer simulations. I also argue that conditional on you should assign a very high credence to the proposition that you live in a computer simulation. However, pace Brueckner, I do not argue that we should believe that we are in simulation. 1 In fact, I believe that we are probably not simulated. The Simulation Argument purports to show only that, as well as , at least one of – is true; but it does not tell us which one.Brueckner also writes: " It is worth noting that one reason why Bostrom thinks that the number of Sims [computer-generated minds with experiences similar to those typical of normal, embodied humans living in a Sim-free early 21 st century world] will vastly outstrip the number of humans is that Sims ‘will run their … ".

In a recent paper in this journal, Ken Olum attempts to refute the doomsday argument by appealing to the self–indication assumption (SIA) that your very existence gives you reason to think that there are many observers. Unlike earlier users of this strategy, Olum tries to counter objections that have been made against (SIA). We argue that his defence of (SIA) is unsuccessful. This does not, however, mean that one has to accept the doomsday argument (or the other counter–intuitive results that (...) flow from related thought–experiments). A developed theory of observation selection effects shows why the doomsday argument is inconclusive, and how one can consistently reject both it and (SIA). (shrink)

Much of our private and public ethical discourse occurs in the giving, receiving, or demanding of an apology, yet we suffer deep confusion regarding what an apology actually is. Most of us have never made explicit precisely what we expect from a full apology and therefore apologizing has become a vague and clumsy ritual. Full apologies can be morally and emotionally powerful, but, as with most valuable things, frauds masquerade as the genuine article. These semblances of apologies often deceive and (...) manipulate, and such duplicity is common between lovers, families, litigants, and nations. In response to this, I propose nine elements that an apology must satisfy in order to be considered categorical. I believe we have such a categorical apology in mind when we seek a full apology. The standards for a categorical apology are rigorous and precise, and I hope to disentangle the distinct elements of apologies. A categorical apology is a rare and burdensome act, and under certain circumstances full apologies may not be possible regardless of how badly we may desire them. While the leading social science accounts by Aaron Lazare and Nicolas Tavuchis aptly demonstrate how apologies lubricate reciprocally egoist relationships, such theories ultimately prove unsatisfying because apologies achieve their highest meaning as morally rich acts. Both Tavuchis and Lazare offer merely descriptive accounts when a prescriptive argument seems necessary. No philosopher, however, has ever devoted a monograph to the topic and only a handful of papers on apologies have appeared in philosophy journals. (shrink)

I argue against the analytic moral functionalist view propounded by Frank Jackson and Philip Pettit. I focus on the ‘input’ clauses of our alleged ‘folk moral theory’. I argue that the examples they give of such input clauses cannot plausibly be interpreted as analytic truths. They are in fact substantive moral claims about the moral ‘domain’. It is a substantive claim that all human beings have equal moral standing. There are those who have rejected this, such as Herman Göring. He (...) was loyal to a sub-class of humankind, but he suffered no conceptual confusion. Claims about what is morally relevant are substantive claims that cannot be known on purely conceptual grounds. (shrink)

John Leslie presents a thought experiment to show that chances are sometimes observer-relative in a paradoxical way. The pivotal assumption in his argument – a version of the weak anthropic principle – is the same as the one used to get the disturbing Doomsday argument off the ground. I show that Leslie's thought experiment trades on the sense/reference ambiguity and is fallacious. I then describe a related case where chances are observer-relative in an interesting way. But not in a paradoxical (...) way. The result can be generalized: At least for a very wide range of cases, the weak anthropic principle does not giverise to paradoxical observer-relative chances. This finding could be taken to give new indirect support to the doomsday argument. (shrink)

Cognitive enhancement takes many and diverse forms. Various methods of cognitive enhancement have implications for the near future. At the same time, these technologies raise a range of ethical issues. For example, they interact with notions of authenticity, the good life, and the role of medicine in our lives. Present and anticipated methods for cognitive enhancement also create challenges for public policy and regulation.

In sum, the non-cognitivist account of motivation is far from unproblematic. The non-cognitivist has trouble telling us what moral attitudes are in a way that is consistent with the phenomenon of variable motivation. Given that the cognitivist has an easy explanation of variable motivation, it seems that cognitivism is preferable to non-cognitivism on the score of motivation, which is a reversal of the way the issue is usually perceived.

For any area of our thought — moral, modal, scientihc, or theological we can ask what explains the way we think. After all, we might never have thought in such terms, or that sort of thought might have been different from the way it is. So there must be some explanation of why it is as it is. Such an explanation would be part of a naturalistic account of the mind.

Why is our knowledge of the past so much more ‘expansive’ (to pick a suitably vague term) than our knowledge of the future, and what is the best way to capture the difference(s) (i.e., in what sense is knowledge of the past more ‘expansive’)? One could reasonably approach these questions by giving necessary conditions for different kinds of knowledge, and showing how some were satisfied by certain propositions about the past, and not by corresponding propositions about the future. I take (...) it that such is the approach of Chapter 6 of Time and Chance (T&C).

ANTI-FORMALISM has become the consensus in aesthetics. But in my view anti-formalism is not true to our aesthetic experience; it gives a revisionary account of the aesthetic properties that we think we find in works of art. The thesis I think we should hold is not extreme formalism—the view that all or almost all aesthetic properties are formal—but the moderate thesis that many are. This view has not been given its due because so many aestheticians have been convinced by anti-formalist (...) arguments. In this short paper, I propose a systematic method for resisting anti-formalist arguments. The method is to apply one of three strategies. These strategies are repeatable archetypes. I shall show these neutralizing strategies at work with seven objections to formalism. (shrink)

Can we hold citizens causally responsible for the outcomes of their voting decisions? They could stand in the causal relationship required for such responsibility either collectively or individually. Recent accounts ascribing responsibility to citizens have primarily taken the collective route because of a major obstacle to using an individualistic approach, namely, the problem of overdetermination: the actions of each citizen do not make an individual difference to, and therefore cannot be a cause of, the overall political outcome. I suggest, drawing (...) on Parfit (1984) and Wright (1985), that we should allow for the idea that individuals can be causally responsible in virtue of making a difference to an outcome not only as an individual, but also as part of a set of agents. I conclude that we therefore can overcome the problem of overdetermination for the individualistic approach and that it merits further investigation. (shrink)

Estimating the financial value of pain informs issues as diverse as the market price of analgesics, the cost-effectiveness of clinical treatments, compensation for injury, and the response to public hazards. Such costs are assumed to reflect a stable trade-off between relief of discomfort and money. Here, using an auction-based health market experiment, we show the price people pay for relief of pain is strongly determined by the local context of the market, determined either by recent intensities of pain, or their (...) immediately disposable income, but not overall wealth. The absence of a stable valuation metric suggests that the dynamic behaviour of health markets is not predictable from the static behaviour of individuals. We conclude that the results follow the dynamics of habit formation models of economic theory, and as such, the study provides the first scientific basis for this type of preference modelling.

In this paper we contrast the idea of a field as a system with an infinite number of degrees of freedom with a recent alternative proposed by Paul Teller in Teller (1990). We show that, although our characterisation lacks the immediate appeal of Teller's, it has more success producing agreement with intuitive categorisations than his does. We go on to extend the distinction to Quantum Mechanics, explaining the important role that it plays there. Finally, we take some time to investigate (...) the way in which strings are to be considered fields, and the important differences with scalar fields. Overall, we aim to show that many types of systems may be viewed as fields, and to point out significant distinctions amongst them, thereby expanding our understanding of what it is to fall in this category.

This paper explains the phenomenon of `entanglement exchange' within the Bohmian approach to quantum mechanics. After explaining Bohmian mechanics and entanglement exchange, in which pairs of particles become entangled without ever interacting causally in the usual, unitary sense, our aim is to use this example, to illustrate how the `pilot wave' mediates non-local correlations. The discussion thus gives a useful new way to think about entanglement exchange, and clarifies the structure of Bohmian mechanics.

Schyns et al. argue that flexibility in categorisation implies “feature creation.” We argue that this notion is flawed, that flexibility can be explained by combinations over fixed feature sets, and that feature creation would in any case fail to explain categorisation. We suggest that flexibility in categorisation is due to pragmatic factors influencing feature combination, rendering feature creation unnecessary.

Cimpian & Salomon's proposal comes unstuck on precisely the claim that inherence is an heuristic, able to deliver simple, shallow outputs that are right most of the time. Instead, the inherence heuristic delivers outputs that imply it is not an heuristic after all, and is simply too fast and too easy a mechanism to do the job of explaining categorisations.

Van Gelder presents the dynamical hypothesis as a novel law of qualitative structure to compete with Newell and Simon's (1976) physical symbol systems hypothesis. Unlike Newell and Simon's hypothesis, the dynamical hypothesis fails to provide necessary and sufficient conditions for cognition. Furthermore, imprecision in the statement of the dynamical hypothesis renders it unfalsifiable.

Clark & Thornton's type-1/-2 distinction is not well-defined. The classes of type-1 and type-2 problems are too broad: many nocomputable functions are type-1 and type-2 learnable. They are also too narrow: trivial functions, such as identity, are neither type-1 nor type-2 learnable. Moreover, the scope of type-1 and type-2 problems appears to be equivalent. Overall, this distinction does not appear useful for machine learning or cognitive science.

Van Gelder's specification of the dynamical hypothesis does not improve on previous notions. All three key attributes of dynamical systems apply to Turing machines and are hence too general. However, when a more restricted definition of a dynamical system is adopted, it becomes clear that the dynamical hypothesis is too underspecified to constitute an interesting cognitive claim.
