The 'content view', in slogan form, is 'Perceptual experiences have representational content'. I explain why the content view should be reformulated to remove any reference to 'experiences'. I then argue, against Bill Brewer, Charles Travis and others, that the content view is true. One corollary of the discussion is that the content of perception is relatively thin (confined, in the visual case, to roughly the output of 'mid-level' vision). Finally, I argue (briefly) that the opponents of the content view are (...) partially vindicated, because perceptual error is due to false belief. (shrink)

"This admirable volume of readings is the first of a pair: the editors are to be applauded for placing the philosophy of color exactly where it should go, in ...

Anything is similar to anything, provided the respects of similarity are allowed to be gerrymandered or gruesome, as Goodman observed.2 But similarity in non-gruesome or—as I shall say—genuine respects is much less ecumenical. Colors, it seems, provide a compelling illustration of the distinction as applied to similarities among properties.3 For instance, in innumerable gruesome respects, blue is more similar to yellow than to purple. But in a genuine respect, blue is more similar to purple than to yellow (genuinely more similar, (...) as I shall sometimes put it). (shrink)

These volumes will serve as useful resources for anyone interested in philosophy of color perception or color science.

Nineteenth-century medical advances were entwined with a conceptual innovation: the idea that many cases of disease which were previously thought to have diverse causes could be explained by the action of a single kind of cause, for example a certain bacterial or parasitic infestation. The focus of modern epidemiology, however, is on chronic non-communicable diseases, which frequently do not seem to be attributable to any single causal factor. This paper is an effort to resolve the resulting tension. The paper criticises (...) the monocausal model of disease, so successful in the nineteenth century. It also argues that a multifactorial model of disease can only be satisfactory if it amounts to more than a mere rejection of the monocausal model. A third alternative, the contrastive model, is proposed and defended on the grounds that it links the notions of disease and of general explanation, while avoiding the philosophical naiveties and practical difficulties of the monocausal model.

A persistent argument against the transitivity assumption of rational choice theory postulates a repeatable action that generates a significant benefit at the expense of a negligible cost. No matter how many times the action has been taken, it therefore seems reasonable for a decision-maker to take the action one more time. However, matters are so fixed that the costs of taking the action some large number of times outweigh the benefits. In taking the action some large number of times on (...) the grounds that the benefits outweigh the costs every time, the decision-maker therefore reveals intransitive preferences, since once she has taken it this large number of times, she would prefer to return to the situation in which she had never taken the action at all. We defend transitivity against two versions of this argument: one in which it is assumed that taking the action one more time never has any perceptible cost, and one in which it is assumed that the cost of taking the action, though (sometimes) perceptible, is so small as to be outweighed at every step by the significant benefit. We argue that the description of the choice situation in the first version involves a contradiction. We also argue that the reasoning used in the second version is a form of similarity-based decision-making. We argue that when the consequences of using similarity-based decision-making are brought to light, rational decision-makers revise their preferences. We also discuss one method that might be used in performing this revision. (shrink)

Saul Kripke’s much discussed Wittgenstein on Rules and Private Language has, I believe, been widely misinterpreted. The purpose of this note is to offer a correction. As it happens, on my reading of Kripke’s text Kripke’s Wittgenstein begins to look recognisably like Wittgenstein himself. But I shall not be concerned here with the question of whether Kripke’s Wittgenstein is Wittgenstein. My only aim is to correct the misinterpretation.

This book carefully engages philosophical arguments for and against open borders, bringing together major approaches to open borders across disciplines and establishing the feasibility of open borders against the charge of utopianism.

Robotic warfare has now become a real prospect. One issue that has generated heated debate concerns the development of ‘Killer Robots’. These are weapons that, once programmed, are capable of finding and engaging a target without supervision by a human operator. From a conceptual perspective, the debate on Killer Robots has been rather confused, not least because it is unclear how central elements of these weapons can be defined. Offering a precise take on the relevant conceptual issues, the article contends (...) that Killer Robots are best seen as executors of targeting decisions made by their human programmers. However, from a normative perspective, the execution of targeting decisions by Killer Robots should worry us. The article argues that what is morally bad about Killer Robots is that they replace human agency in warfare with artificial agency, a development which should be resisted. Finally, the article contends that the issue of agency points to a wider problem in just war theory, namely the role of moral rights in our normative reasoning on armed conflict. (shrink)

The Dangerous Book for Boys Abstract: Seventeenth and eighteenth century discussions of the senses are often thought to contain a profound truth: some perceptible properties are secondary qualities, dispositions to produce certain sorts of experiences in perceivers. In particular, colors are secondary qualities: for example, an object is green iff it is disposed to look green to standard perceivers in standard conditions. After rebutting Boghossian and Velleman’s argument that a certain kind of secondary quality theory is viciously circular, we discuss (...) three main lines of argument for the secondary quality theory. The first is inspired by an intuitively compelling picture of perception articulated by Reid; the second is that the secondary quality theory is a conceptual truth; the third line of argument is presented in Johnston’s influential paper ‘How to speak of the colors’. We conclude that all these arguments fail, and that the secondary quality theory is unmotivated. Keywords: color, secondary quality, disposition, vision, perception.. (shrink)

The “fair benefits” approach to international research is designed to produce results that all can agree are fair without taking a stand on divisive questions of justice. But its appealing veneer of collaboration masks ambiguities at both a conceptual and an operational level. An attempt to put it into practice would look a lot like an auction, leaving little reason to think the outcomes will satisfy even minimal conditions of fairness.

To judge from the rash of recent law review articles, it is a miracle that research with human subjects in the U.S. continues to draw breath under the asphyxiating heel of the rent-seeking, creativity-stifling, jack-booted bureaucrethics that is the current system of research ethics oversight and review. Institutional Review Boards, sometimes called Research Ethics Committees, have been accused of perpetrating “probably the most widespread violation of the First Amendment in our nation's history,” resulting in a “disaster, not only for academics, (...) but for the whole nation.” One member of the President's Council on Bioethics went so far as to assert, “There has been no greater damage to academic freedom in the United States in my lifetime. And my lifetime encompasses McCarthy and it encompasses political correctness, both.” Locked in the bureaucratic “iron cage” of IRB oversight, critics charge that researchers have been transformed into a vulnerable, exposed population, subject to domination, that has been likened in one case to a kind of “Tuskegee in reverse.”.

Dummctt argues that classical quantification is illegitimate when the domain is given as the objects which fall under an indefinitely extensible concept, since in such cases the objects are not the required definite totality. The chief problem in understanding this complex argument is the crucial but unexplained phrase 'definite totality' and the associated claim that it follows from the intuitive notion of set that the objects over which a classical quantifier ranges form a set. 'Definite totality' is best understood as (...) disguised plural talk like Cantor's 'consistent multiplicity', although this does not help in understanding how a totality could be anything other than definite. Moreover, contrary to his claims, Dummett's own notion of set is not intuitive and he does not demystify the set-theoretic paradoxes. In conclusion, it is argued that Dummett's context principle is responsible for the incoherent projection of the haziness of a conception of some objects onto reality. (shrink)

There is extensive evidence that adults, children, and some non-human species, represent routine events in the form of hierarchically structured 'action scripts,' and show superior recall and imitation of information at relatively high-levels of this hierarchy. Here we investigate the hypothesis that a 'hierarchical bias' operates in human cultural transmission, acting to impose a hierarchical structure onto descriptions of everyday events, and to increasingly describe those events in terms of higher hierarchical levels. Descriptions of three everyday events expressed entirely in (...) terms of basic low-level actions were transmitted along ten chains each containing four adult human participants. It was found that the proportion of low-level information showed a significant linear decrease with transmission generation, while the proportions of medium- and high-level information showed significant linear increases, consistent with the operation of a hierarchical bias. The findings additionally provide support for script theory in general, and are discussed in relation to hierarchical imitation in non-human primates. (shrink)

Climate change is often described as an existential risk to the human species, but this terminology has generally been avoided in the climate-justice literature in analytic philosophy. I investigate the source of this disconnect and explore the prospects for incorporating the idea of climate change as an existential risk into debates about climate justice. The concept of existential risk does not feature prominently in these discussions, I suggest, because assumptions that structure ‘ideal’ accounts of climate justice ensure that the prospect (...) of climate change as an extinction-level threat does not arise. Given persistent noncompliance with mitigation duties, however, we have reason to revisit these assumptions. I argue that the most promising way for theories of climate justice to account for the significance of existential risk is to look to the practices of protest and resistance in which a concern about extinction or global catastrophe is frequently given expression.

Nine issues of fundamental importance for business ethics are examined with a view to encouraging researchers in the field to direct their attention to them in the 1990s and beyond. The issues are related to organized labour, social dumping, international finance and Third World debt, tobacco promotion, arms trade, wealth concentration and taxation, pollution and resource depletion, international trading blocks, and the Canadian Business Council on National Issues and other business organizations.

This book draws on studies of movement, gesture, and early film to offer a series of readings on repetition through the body in Homer. Each chapter presents an argument based on a specific posture, action or gesture, through which to rethink epic practices of embodiment and formularity.

Epicurus argued that the good life is the pleasurable life. He also argued that “death is nothing to us”. These claims appear in tension. For, if pleasure is good, then it seems that death is bad when it deprives us of deeply enjoyable time alive. Here, I offer an Epicurean view of pleasure and the complete life which dissolves this tension. This view is, I contend, more appealing than critics of Epicureanism have allowed, in part because it assigns higher value (...) to pleasures that we produce by exercising our rational capacities and by establishing control over our lives.

Stuart Rachels and Larry Temkin have offered a purported counterexample to the acyclicity of the relationship “all things considered better than”. This example invokes our intuitive preferences over pairs of alternatives involving a single person’s painful experiences of varying intensity and duration. These preferences, Rachels and Temkin claim, are confidently held, entirely reasonable, and cyclical. They conclude that we should drop acyclicity as a requirement of rationality. I argue that, together with the findings of recent research on the way people (...) evaluate episodes of pain, the use of a heuristic known as similarity-based decision-making explains why our intuitive preferences may violate acyclicity in this example. I argue that this explanation should lead us to regard these preferences with suspicion, because it indicates that they may be the result of one or more biases. I conclude that Rachels’ and Temkin’s example does not provide sufficient grounds for rejecting acyclicity. (shrink)

This paper considers an important recent contribution by Miguel Hernán to the ongoing debate about causal inference in epidemiology. Hernán rejects the idea that there is an in-principle epistemic distinction between the results of randomized controlled trials and observational studies: both produce associations which we may be more or less confident interpreting as causal. However, Hernán maintains that trials have a semantic advantage. Observational studies that seek to estimate causal effect risk issuing meaningless statements instead. The POA proposes a solution (...) to this problem: improved restrictions on the meaningful use of causal language, in particular “causal effect”. This paper argues that new restrictions in fact fail their own standards of meaningfulness. The paper portrays the desire for a restrictive definition of causal language as positivistic, and argues that contemporary epidemiology should be more realistic in its approach to causation. In a realist context, restrictions on meaningfulness based on precision of definition are neither helpful nor necessary. Hernán’s favoured approach to causal language is saved from meaninglessness, along with the approaches he rejects. (shrink)

Resumo Este artigo defende o ponto de vista de que as bases da ciência cognitiva contemporânea estão em sintonia com o pensamento de Merleau-Ponty, em seus aspectos antiobjetivista e antirrepresentacionalista. A ideia de representação mental é contestada, tanto na CC quanto no pensamento de Merleau-Ponty. A cognição não espelha um mundo exterior independente dos sujeitos incorporados. O mundo é um existencial, como afirmam Merleau-Ponty e a CC. A hipótese da representação mental supõe que o mundo pode ser percebido de forma (...) independente do sujeito que percebe. Isso não é verdade. A percepção depende da forma como o sujeito age em seu mundo percebido. Todas as estimulações que o organismo encontra só são possíveis pelos seus movimentos precedentes que resultam na exposição do órgão receptor às influências externas. Os estímulos sensoriais que o organismo encontra dependem diretamente do seu comportamento motor e a forma como o organismo se move depende diretamente das consequências sensoriais dos seus comportamentos anteriores.This article defends the view that the foundations of contemporary cognitive science are in tune with Merleau-Ponty’s thinking in its anti-objectivist and anti-representationalist aspects. The idea of mental representation is contested both in CC and in Merleau-Ponty’s thinking. Cognition does not mirror an outside world independent of embodied subjects. The world is an existential one as Merleau-Ponty and the CC say. The mental representation hypothesis assumes that the world can be perceived independently of the perceiving subject. This is not true. Perception depends on how the subject acts in his perceived world. All the stimulations that the organism finds are only possible by its previous movements that result in the exposure of the receiving organ to external influences. The sensory stimuli that the organism finds depend directly on its motor behavior and the way the organism moves depends directly on the sensory consequences of its previous behaviors. (shrink)

Realism in Duhem's Natural Classification. Pierre Duhem is an outstanding exponent of empiricism. According to the empiricist view scientific laws and theories merely describe formal relations between observable phenomena. Duhems' important notion of natural classification is intended to explain the predictive success of science. I shall argue that it can only be interpreted realistically. Besides the success of science, two further arguments are put forward in favor of realism: the fact that laws of nature are necessary, and the extension of (...) observation by using instruments.

This article explores the relationship between Gilles Deleuze's philosophical endeavours and Marxism, with a particular focus on his unfinished work, Grandeur de Marx. Despite the collapse of Soviet socialism, Deleuze acknowledged that his philosophical pursuits were profoundly intertwined with Marxist thought. His insistence on this connection was not a mere expression of regret or an apology for his political leanings. In the 1990s, as neoliberal globalisation spread beyond the United States and Europe, Marxism persisted as a rallying cry for resistance. (...) The ascendancy of global capitalism was not a consequence of Marxism's failure; rather, it was a manifestation of what Marx had presciently predicted in his works. Thus, Deleuze's unfinished project on Marx can be viewed as a response to anti-Marxist reactionism from a distinct vantage point. While several interpretations of Deleuze's unwritten Marx exist, the argument in this essay is that Deleuze attempted to recreate the conditions for Marx's critical analysis by employing communism as an event.

Should we embrace nihilism, as Nolen Gertz suggests, or try to overcome it? For Nietzsche, nihilism must be overcome – if we're strong enough. The key, argues Alex Silk, is to see how nihilistic beliefs – that, say, nothing matters – derive from nihilistic feelings and bodily states. Understanding the basic features of human nature and experience at the root of nihilism paves the way toward a healthier, affirming perspective on ourselves and human life. Nietzsche’s rhetorical style helps us (...) incorporate such a perspective by engaging our feelings as well as our rational faculties. (shrink)

We fine tune the distinction between the possible and what can be, mention some of the consequences and argue that the difference between material and logical implication is that of between what can be and what could have been.

SummaryI argue that language is a social phenomenon and that thoughts take place in a linguistic medium of representation. Davidson's private language approach to communication is reviewed and criticised in sections 2 and 3, respectively. It is shown that Dretske's recent definition of thought is not narrow enough to exclude algorithmic symbol manipulations done by computers from being thoughts. The difference between mere algorithmic symbol manipulation and thought is to be found in the human ability to infer the truth value (...) of certain self‐referential representations such as Gödel sentences . Section 4 also contains an argument to the effect that only universal linguistic systems allow for the construction of such decidable self‐referential representations and are, therefore, the only appropriate media of thought. Some speculations on the relation between thought and internal symbol manipulation follow. The whole issue discussed in this essay indicates that some form of externalism is required to account for thought. (shrink)

Pessoa et al. misinterpret some of Dennett's discussion of filling-in. Their argument against the representational conception of vision and for a Gibsonian alternative is also flawed.
