Edelman's memory-based approach to visual representation is preferable to parts-based alternatives. However, the existing algorithms for learning the shape prototypes are biologically implausible because they are nonlocal and nonconstructive. There is an alternative learning algorithm that constructs a mixture model of prototypes on-line, using only local information, and is more biologically plausible and may perform sufficiently well.

In lieu of an abstract, here is a brief excerpt of the content:Can Two Wrongs Make a Right?Toby Williamson (bio)"Service users, carers, and professionals disagree about the nature of mental disorder in startling new revelation!" On first appearances Fulford and Colombo's use of linguistic-analytic and empirical methods to demonstrate this point may not seem as if it is telling those in the mental health world anything that they do not already know. The bipolar/dialectical axis (choose your preferred term depending (...) on your ideological position) with the anti-psychiatry movement at one end and the biogeneticists at the other is both well-known and well-documented. Yet it is precisely that flippancy, and the practical implications that flow from it, that make this work so fundamentally important to the theory, application, and experience of mental health practice at the beginning of the twenty-first century.Discussions about different models of mental disorder usually play themselves out in arguments within services, or between services and service users and informal carers, about the most appropriate approach to take in addressing a service users needs, or in abstract discussions (often over a drink after work) about the nature of mental health and mental health problems. From blood and fur flying in the bull pit, to swallows endlessly chasing their tails high in the sky. Sadly, the results of this all too often are bitter and unresolved conflicts, different parties digging themselves even further into defensive, entrenched positions, and the least powerful (usually service users) suffering the most as a consequence. Both sides believe the other to be wrong yet cannot convince them of this; an example, albeit with slight variation, of two wrongs not making a right. Rarely are the debates grounded in a constructive, creative, and problem-solving approach on a day-to-day basis, partly because hitherto there does not seem to have been either sufficient empirical evidence to base this upon, or the conceptual as well as practical tools with which to grapple with the issues.Generally speaking, mainstream research in mental health has tended to focus on issues such as symptoms and treatment interventions (James and Burns 2002). However, surveys of service users' views still show considerable problems in the way services are received and experienced by users (Rose 2001). Other surveys, together with user-led research, such as Strategies for Living at the Mental Health Foundation, have also shown how the focus of users' concerns maybe very different to that of service providers (Faulkner and Layzell 2000; Nicholls et al, 2003; Repper 2000). Indeed, a piece of research carried out in the 1990s, which would probably still hold true today, showed that service users prioritized practical issues such as personal finance, housing, and social support, whereas professionals saw issues such as treatment and monitoring as being the highest priority (Shepherd, Murray, and Muijen 1995). Combining this, one might well argue that there is fairly clear evidence of the [End Page 159] differences in value bases and models of mental disorder deployed by service users and mental health professionals. However, actually trying to scientifically map this, and taking into account differences between professions, not to mention the views of informal carers, would appear to be a gargantuan task. Yet Fulford and Colombo appear to have very successfully done this in the research supporting this article, as well as the article itself. Their discussion of the concept of mental disorder, and the difficulties of defining it, not only effortlessly demonstrates the theoretical and philosophical problems that lie at the heart of psychiatry and mental health systems, of which Professor Fulford along with others has already written extensively (Dickenson and Fulford 2000), but also should resonate at a very practical level for most people who have been at the providing or receiving end of mental health services. But going beyond this they also provide perhaps the simplest, yet most effective solution—to embrace diversity and find ways of working with it, rather than running shy of it or even worse, attempting to homogenize it. As they say, "the difficulties in use presented by the concept of mental disorder are not a liability, heuristically speaking, but an asset" (Fulford and Colombo 2004, 132).The article is also very timely because...

In a recent series of papers, Timothy Williamson argues that one can reach Edmund Gettier’s conclusion that the justified-true-belief (JTB) theory of knowledge is insufficient for knowledge by constructing Gettier cases in the framework of epistemic logic. In this paper, I argue, however, that Williamson’s Gettier cases in the framework of epistemic logic crucially turn on an assumption that the JTB theorist can plausibly and justifiably reject. In particular, I argue that it is rational for the JTB theorist (...) to reject Williamson’s preferred epistemic accessibility relation in favor of one for which Gettier cases in epistemic logic do not arise. Thus, I conclude that Williamson’s Gettier cases in epistemic logic do not genuinely threaten the tripartite theory of knowledge. (shrink)

Lewis (The Journal of Philosophy, 65(5), 113–126, 1968) attempts to provide an account of modal talk in terms of the resources of counterpart theory, a first-order theory that eschews transworld identity. First, a regimentation of natural language modal claims into sentences of a formal first-order modal language L is assumed. Second, a translation scheme from L-sentences to sentences of the language of the theory is provided. According to Hazen (The Journal of Philosophy, 76(6), 319–338, 1979) and Fara & Williamson (...) (Mind, 114(453), 1–30, 2005), the account cannot handle certain natural language modal claims involving a notion of actuality. The challenge has two parts. First, in order to handle such claims, the initial formal modal language that natural language modal claims are regimented into must extend L with something like an actuality operator. Second, certain ways that Lewis’ translation scheme for L might be extended to accommodate an actuality operator are unacceptable. Meyer (Mind, 122(485), 27–42, 2013) attempts to defend Lewis’ approach. First, Meyer holds that in order to handle such claims, the formal modal language L$$^*$$ ∗ that we initially regiment our natural language claims into need not contain an actuality operator. Instead, we can make do with other resources. Next, Meyer provides an alternative translation scheme from L$$^*$$ ∗ -sentences to sentences of an enriched language of counterpart theory. Unfortunately, Meyer’s approach fails to provide an appropriate counterpart theoretic account of natural language modal claims. In this paper, I demonstrate that failure. (shrink)

Quantified modal logic has reputation for complexity. Completeness results for the various systems appear piecemeal. Different tactics are used for different systems, and success of a given method seems sensitive to many factors, including the specific combination of choices made for the quantifiers, terms, identity, and the strength of the underlying propositional modal logic. The lack of a unified framework in which to view QMLs and their completeness properties puts pressure on those who develop, apply, and teach QML to work (...) with the simplest systems, namely those that adopt the Barcan Formulas and predicate logic rules for the quantifiers. In these systems, the quantifier ranges over a fixed domain of possible individuals, so advocates of these logics are sometimes called possibilists. A literature has grown up rationalizing the choice of possibilist logics despite ordinary intuitions that the resulting theorems are too strong.Williamson even takes the view that the complications to be faced within the weaker logics “are a warning sign of philosophical error”. It is the purpose of this paper to show that abandonment of the weaker QMLs is excessively fainthearted, since most QMLs can be given relatively simple formulations within one general framework. Given the straightforward nature of the systems and their completeness results, the purported complications evaporate, along with any philosophical warnings one might have associated with them.

Let me tell you what philosophy is about, then about how Sydney does it in its own special way. Does life have a meaning, and if so what is it? What can I be certain of, and how should I act when I am not certain? Why are the established truths of my tribe better than the primitive superstitions of your tribe? Why should I do as I’m told? Those are questions it’s easy to avoid, in the rush to acquire (...) goods and prestige. Even for many of a more serious outlook, they are questions easy to dismiss with excuses like “it’s all a matter of opinion” or “let’s get on with practical matters” or “they’re too hard”. They are questions that may be ignored, but they do not go away. They’re philosophical questions. There’s a right way to approach them – you read the writings of the classical and recent philosophers and consider carefully their arguments back and forth. There are many wrong ways to approach them, such as choosing at random among the ideas your parents or friends or gurus have, or ideas that feel good. Or you can just not bother. Sydney has a certain reputation for superficiality in this regard. A character in David Williamson’s Emerald City says “No-one in Sydney ever wastes time debating the meaning of life — it’s getting yourself a water frontage”, says If you have a Writers Festival or a conference on Happiness in Sydney, you don’t normally expect philosophers to be invited.

Timothy Williamson gives an original and provocative treatment of deep metaphysical questions about existence, contingency, and change, using the latest resources of quantified modal logic. Contrary to the widespread assumption that logic and metaphysics are disjoint, he argues that modal logic provides a structural core for metaphysics.

Vagueness provides the first comprehensive examination of a topic of increasing importance in metaphysics and the philosophy of logic and language. Timothy Williamson traces the history of this philosophical problem from discussions of the heap paradox in classical Greece to modern formal approaches such as fuzzy logic. He illustrates the problems with views which have taken the position that standard logic and formal semantics do not apply to vague language, and defends the controversial realistic view that vagueness is a (...) kind of ignorance--that there really is a grain of sand whose removal turns a heap into a non-heap, but we cannot know which one it is.

When I take off my glasses, the world looks blurred. When I put them back on, it looks sharpedged. I do not think that the world really was blurred; I know that what changed was my relation to the distant physical objects ahead, not those objects themselves. I am more inclined to believe that the world really is and was sharp-edged. Is that belief any more reasonable than the belief that the world really is and was blurred? I see more (...) accurately with my glasses on than off, so visual appearances when they are on have some cognitive priority over visual appearances when they are off. If I must choose which kind of visual appearance to take at face value, I will choose the sharp-edged look. But what should I think when I see a mist, which looks very blurred however well I am seeing? Indeed, why choose to take any of the looks at face value? Why not regard all the choices as illegitimate projections of ways of seeing the world onto the world itself? (shrink)

The second volume in the _Blackwell Brown Lectures in Philosophy_, this volume offers an original and provocative take on the nature and methodology of philosophy. Based on public lectures at Brown University, given by the pre-eminent philosopher, Timothy Williamson Rejects the ideology of the 'linguistic turn', the most distinctive trend of 20th century philosophy Explains the method of philosophy as a development from non-philosophical ways of thinking Suggests new ways of understanding what contemporary and past philosophers are doing.

In this paper we discuss how Causal Decision Theory should be modified to handle a class of problematic cases involving deterministic laws. Causal Decision Theory, as it stands, is problematically biased against your endorsing deterministic propositions (for example it tells you to deny Newtonian physics, regardless of how confident you are of its truth). Our response is that this is not a problem for Causal Decision Theory per se, but arises because of the standard method for assessing the truth of (...) certain counterfactuals. The truth of deterministic laws is `modally fragile' on the standard semantics for counterfactuals: if determinism is true and you were to do otherwise, the laws would be different. We provide two ways of avoiding this problem: 1) supplement the standard semantics for counterfactuals with impossible worlds, or 2) introduce rigid designators into the description of problematic decision situations. We argue that both of these approaches are well-motivated and can be readily incorporated into Lewisian Causal Decision Theory. (shrink)

This chapter presents an overview of the major interpretations of probability followed by an outline of the objective Bayesian interpretation and a discussion of the key challenges it faces. I discuss the ramifications of interpretations of probability and objective Bayesianism for the philosophy of mathematics in general.

The paper clarifies and defends the orthodox view that counterfactual conditionals with impossible antecedents are vacuously true against recent criticisms. It argues that apparent counterexamples to orthodoxy result from uncritical reliance on a fallible heuristic used in the processing of conditionals. A comparison is developed between such counterpossibles and vacuously true universal generalizations.

Understandably absorbed in technical details, discussion of the semantic paradoxes risks losing sight of broad methodological principles. This chapter sketches a general approach to the comparison of rival logics, and applies it to argue that revision of classical propositional logic has much higher costs than its proponents typically recognize.

Former Google advertising strategist, now Oxford-trained philosopher James Williams launches a plea to society and to the tech industry to help ensure that the technology we all carry with us every day does not distract us from pursuing our true goals in life. As information becomes ever more plentiful, the resource that is becoming more scarce is our attention. In this 'attention economy', we need to recognise the fundamental impacts of our new information environment on our lives in order (...) to take back control. Drawing on insights ranging from Diogenes to contemporary tech leaders, Williams's thoughtful and impassioned analysis is sure to provoke discussion and debate. Williams is the inaugural winner of the Nine Dots Prize, a new Prize for creative thinking that tackles contemporary social issues. This title is also available as Open Access. (shrink)

Imagine a philosophy conference in Presocratic Greece. The hot question is: what are things made of? Followers of Thales say that everything is made of water, followers of Anaximenes that everything is made of air, and followers of Heraclitus that everything is made of fire. Nobody is quite clear what these claims mean, and some question whether the founders of the respective schools ever made them. But amongst the groupies there is a buzz about all the recent exciting progress. The (...) mockers and doubters make plenty of noise too. They point out that no resolution of the dispute between the schools is in sight. They diagnose Thales, Anaximenes and Heraclitus as suffering from a tendency to overgeneralize. We can intelligibly ask what bread is made of, or what houses are made of, but to ask what things in general are made of is senseless, some suggest, because the question is posed without any conception of how to verify an answer; language has gone on holiday. Paleo-pragmatists invite everyone to relax, forget their futile pseudo-inquiries and do something useful instead. (shrink)

The philosophical relevance of experimental psychology is hard to dispute. Much more controversial is the so‐called negative program's critique of armchair philosophical methodology, in particular the reliance on ‘intuitions’ about thought experiments. This chapter responds to that critique. It argues that, since the negative program has been forced to extend the category of intuition to ordinary judgments about real‐life cases, the critique is in immediate danger of generating into global scepticism, because all human judgments turn out to depend on intuitions. (...) Recently, some proponents of the negative program have tried to demarcate the target of their critique more narrowly. However, their attempts are still far too indiscriminate, and over‐generate scepticism. Nevertheless, once experimental philosophy has refined its own methodology, it may contribute to the refinement of the methodology of mainstream philosophy, by filtering out the effects of cognitive bias, although it offers no prospect of doing without judgments on real or imaginary cases.

The Epicurean philosophical system has enjoyed much recent scrutiny, but the question of its philosophical ancestry remains largely neglected. It has often been thought that Epicurus owed only his physical theory of atomism to the fifth-century BC philosopher Democritus, but this study finds that there is much in his ethical thought which can be traced to Democritus. It also finds important influences on Epicurus in Democritus' fourth-century followers such as Anaxarchus and Pyrrho, and in Epicurus' disagreements with his own Democritean (...) teacher Nausiphanes. The result is not only a fascinating reconstruction of a lost tradition, but also an important contribution to the philosophical interpretation of Epicureanism, bearing especially on its ideal of tranquillity and on the relation of ethics to physics.

This chapter aims to attempt no more than to make some informal and unsystematic remarks on the transformation of analytic philosophy. It deals with a few sketchy remarks on the historiography of recent analytic philosophy. Writing in 1981, David Lewis described “a reasonable goal for a philosopher” as bringing one’s opinions into stable equilibrium. A natural comparison is between Lewis’s Quinean or at least post‐Quinean methodology and the methodology of Peter Strawson, Quine’s leading opponent from the tradition of ordinary language (...) philosophy. Analytic epistemology provides a good case study of the philosophical application of Gricean pragmatics outside the philosophy of language. On Michael Dummett picture of the history of philosophy, Descartes had made epistemology first philosophy, the engine for the rest of philosophy, and then Frege had replaced epistemology by the philosophy of language as first philosophy. The chapter suggests that philosophy sometimes already uses an abductive methodology and ought to use it more in the future. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:James and Waismann on Temperament in PhilosophyJohn Cappsfor william james, philosophyis inextricably linked to what he calls temperament. In the first of his Pragmatismlectures, he claims that "the history of philosophy is to a great extent that of a certain clash of human temperaments" ( Pragmatism11), while conceding that this will strike many philosophers as "undignified." In a similar vein, he elsewhere writes that philosophy seeks "by (...) hard reasoning for results emotionally valuable" ( Some Problems of Philosophy11). It's not hard to see a connection between these two claims: whether a philosophical conclusion is "emotionally valuable" will presumably depend, at least in part, on the reader's temperament. A philosophical work will leave some readers cold while resonating with others; some philosophy will engage one's interest and energy, while other philosophy will seem not so much mistaken as alien, remote from what one might ever find useful, interesting, or enlightening.James's meta-philosophical claim—his philosophy of philosophy—has received surprisingly little attention. Much of the literature has focused instead on what he meant by "temperament" in the context of nineteenth- and early twentieth-century theories of psychology and brain science. Much less attention has been paid to whether he is right and what the consequences would be if he is right. 1I aim to address this gap by first raising some fundamental issues with James's position. To see better what he should have said, I will then turn to some later but surprisingly similar remarks by the Anglo-Austrian philosopher and mathematician Friedrich Waismann, before turning to a more recent account of philosophical methodology defended by Timothy Williamson.1. James on Philosophy and TemperamentHilary and Ruth Anna Putnam have written that "perhaps the most shocking claim that James makes—the claim that is the centerpiece of the very first of the Lectures on Pragmatism—is that the decision we make on any metaphysical [End Page 46]question … is and ought to be a matter of 'temperament'" (227). While the Putnams do not explain what makes this his "most shocking" claim, it is likely because James accuses philosophers of being either systematically dishonest or self-deluded. Here is what James writes:Of whatever temperament a professional philosopher is, he tries when philosophizing to sink the fact of his temperament. Temperament is no conventionally recognized reason, so he urges impersonal reasons only for his conclusions. Yet his temperament really gives him a stronger bias than any of his more strictly objective premises. It loads the evidence for him one way or the other, making for a more sentimental or a more hard-hearted view of the universe, just as this fact or that principle would. He trustshis temperament…. Yet in the forum he can make no claim, on the bare ground of his temperament, to superior discernment or authority. There arises thus a certain insincerity in our philosophic discussions: the potentest of all our premises is never mentioned.( Pragmatism11)According to James, then, one's "temperament" plays an important role in determining the sorts of philosophical positions one finds congenial—and yet professional philosophers are either in denial that temperament plays this role or are actively committed to concealing this fact. Nor does James limit his claim, as the Putnams suggest, to only metaphysical questions: while he tends to focus on more large-scale alternatives (empiricism vs. rationalism, atheism vs. theism—perhaps because the lectures were delivered before a popular audience), the same point should hold across the board. So whether it is the choice between consequentialism vs. deontological ethical theories, or procedural vs. substantive accounts of justice, or functionalist vs. behaviorist philosophies of mind, James would argue that temperament plays a crucial role. 2I will refer to this as his "temperament thesis" (TT): TT: One's philosophical commitments are, in part, a function of one's temperament. A few points of clarification are in order. First, while James describes temperament as providing the "potentest" support for philosophical claims, he does not claim that it is decisive or that it swamps all other considerations. Temperament "loads the evidence" but can apparently be overridden when sufficient evidence or compelling... (shrink)

All aspects of the philosophy of music are discussed, including music and the cosmos, music's value, music's relation (...) to the other arts, the problem of opera, the origins of musical genius, music's emotional impact, the moral effects of music, the ontology of musical works, and the relevance of music's historical context. The volume will be valuable for students and scholars in philosophy and musicology, and all who are interested in the ways in which philosophers throughout history have thought about music. (shrink)

The infant mortality rate in Liberia is 50 times higher than it is in Sweden, whilst a child born in Japan has a life expectancy at birth of more than double that of one born in Zambia. 1 And within countries, we see differences which are nearly as great. For example, if you were in the USA and travelled the short journey from the poorer parts of Washington to Montgomery County Maryland, you would find that ‘for each mile travelled life (...) expectancy rises about a year and a half. There is a twenty-year gap between poor blacks at one end of the journey and rich whites at the other’. (Marmot, 2004, p.2). There are two types of questions which it is important to ask about inequalities in health such as these. The first are social scientific questions about the extent of inequalities in health and the factors which are causally responsible for these inequalities. Examples of social scientific questions to ask might be: how do infant mortality rates in the UK differ according to social class? What is the difference in life expectancy between Japanese who emigrate to the US and those who remain in Japan? Why do civil servants in higher ranked jobs tend to live longer than civil servants in lower ranked jobs? The second type are normative questions about the reasons we have to care about inequalities in health. Important normative questions to answer are: which inequalities in health should we care about (all inequalities or merely some of them)? When is an inequality in health unjust? How should we weigh our concern for equality in health against other factors such as maximising the.. (shrink)

Two opposing tendencies in the philosophy of language go by the names of ‘referentialism’ and ‘inferentialism’ respectively. In the crudest version of the contrast, the referentialist account of meaning gives centre stage to the referential semantics for a language, which is then used to explain the inference rules for the language, perhaps as those which preserve truth on that semantics (since a referential semantics for a language determines the truth-conditions of its sentences). By contrast, the inferentialist account of meaning gives (...) centre stage to the inference rules for the language, which are then used to explain its referential semantics, perhaps as the semantics on which the rules preserve truth. On pain of circularity, we cannot combine both directions of explanation. (shrink)

Why is American punishment so cruel? While in continental Europe great efforts are made to guarantee that prisoners are treated humanely, in America sentences have gotten longer and rehabilitation programs have fallen by the wayside. Western Europe attempts to prepare its criminals for life after prison, whereas many American prisons today leave their inhabitants reduced and debased. In the last quarter of a century, Europe has worked to ensure that the baser human inclination toward vengeance is not reflected by state (...) policy, yet America has shown a systemic drive toward ever increasing levels of harshness in its criminal policies. Why is America so short on mercy? In this deeply researched, comparative work, James Q. Whitman reaches back to the 17th and 18th centuries to trace how and why American and European practices came to diverge. Eschewing the usual historical imprisonment narratives, Whitman focuses instead on intriguing differences in the development of punishment in the age of Western democracy. European traditions of social hierarchy and state power, so consciously rejected by the American colonies, nevertheless supported a more merciful and dignified treatment of offenders. The hierarchical class system on the continent kept alive a tradition of less-degrading "high-status" punishments that eventually became applied across the board in Europe. The distinctly American, draconian regime, on the other hand, grows, Whitman argues, out of America's longstanding distrust of state power and its peculiar, broad-brush sense of egalitarianism. Low-status punishments were evenly meted out to all offenders, regardless of class or standing. America's unrelentingly harsh treatment of trangressors--this "equal opportunity degradation"-- is, in a very real sense, the dark side of the nation's much vaunted individualism. A sobering look at the growing rift between the United States and Europe, Harsh Justice exposes the deep cultural roots of America's degrading punishment practices. (shrink)

When we talk about intellectual property, it is often implicitly assumed that we are talking about private intellectual property. However, private property and the idea of private ownership do not exhaust the possibilities for accounts of ownership and of property. There are other ways that ownership can operate, such as common property. A resource is common property if its use is ‘governed by rules whose point is to make them available for use by all or any members of the society.’.

Experiences of embodied remembering are familiar and diverse. We settle bodily into familiar chairs or find our way easily round familiar rooms. We inhabit our own kitchens or cars or workspaces effectively and comfortably, and feel disrupted when our habitual and accustomed objects or technologies change or break or are not available. Hearing a particular song can viscerally bring back either one conversation long ago, or just the urge to dance. Some people explicitly use their bodies to record, store, or (...) cue memories. Others can move skilfully, without stopping to think, in complex and changing environments thanks to the cumulative expertise accrued in their history of fighting fires, or dancing, or playing hockey. The forms of memory involved in these cases may be distinct, operating at different timescales and levels, and by way of different mechanisms and media, but they often cooperate in the many contexts of our practices of remembering.

This article discusses some philosophical theories of causation and their application to several areas of science. Topics addressed include regularity, counterfactual, and causal process theories of causation; the causal interpretation of structural equation models and directed graphs; independence assumptions in causal reasoning; and the role of causal concepts in physics. In connection with this last topic, this article focuses on the relationship between causal asymmetries, the time-reversal invariance of most fundamental physical laws, and the significance of differences among varieties of (...) differential equations in causal interpretation. It concludes with some remarks about “grounding” special science causal generalizations in physics. (shrink)

Metaphysical modalities are definable from counterfactual conditionals, and the epistemology of the former is a special case of the epistemology of the latter. In particular, the role of conceivability and inconceivability in assessing claims of possibility and impossibility can be explained as a special case of the pervasive role of the imagination in assessing counterfactual conditionals, an account of which is sketched. Thus scepticism about metaphysical modality entails a more far-reaching scepticism about counterfactuals. The account is used to question the (...) significance of the distinction between a priori and a posteriori knowledge. (shrink)
