From one of the most influential scientists of our time, a dazzling exploration of the hidden laws that govern the life cycle of everything from plants and animals to the cities we live in. The former head of the Sante Fe Institute, visionary physicist Geoffrey West is a pioneer in the field of complexity science, the science of emergent systems and networks. The term "complexity" can be misleading, however, because what makes West's discoveries so beautiful is that he has (...) found an underlying simplicity that unites the seemingly complex and diverse phenomena of living systems, including our bodies, our cities and our businesses. Fascinated by issues of aging and mortality, West applied the rigor of a physicist to the biological question of why we live as long as we do and no longer. The result was astonishing, and changed science, creating a new understanding of energy use and metabolism: West found that despite the riotous diversity in the sizes of mammals, they are all, to a large degree, scaled versions of each other. If you know the size of a mammal, you can use scaling laws to learn everything from how much food it eats per day, what its heart-rate is, how long it will take to mature, its lifespan, and so on. Furthermore, the efficiency of the mammal's circulatory systems scales up precisely based on weight: if you compare a mouse, a human and an elephant on a logarithmic graph, you find with every doubling of average weight, a species gets 25% more efficient--and lives 25% longer. This speaks to everything from how long we can expect to live to how many hours of sleep we need. Fundamentally, he has proven, the issue has to do with the fractal geometry of the networks that supply energy and remove waste from the organism's body. (shrink)

Sir Geoffrey Lloyd presents a cross-disciplinary exploration of the unity and diversity of the human mind. He discusses cultural variations with regard to ideas of colour, emotion, health, the self, agency and causation, reasoning, and other fundamental aspects of human cognition. He draws together scientific, philosophical, anthropological, and historical arguments in showing how our evident psychic diversity can be reconciled with our shared humanity.

It has recently emerged that malarial, toxoplasmodial and related parasites contain a vestigial plastid (the organelle in which photosynthesis occurs in plants and algae). The function of the plastid in these obligate intracellular parasites has not been established. It seems likely that modern apicomplexans derive from photosynthetic predecessors, which perhaps formed associations with protists and invertebrates and abandoned autotrophy in favour of parasitism. Recognition of a third genetic compartment in these parasites proffers alternative strategies for combating a host of important (...) human and animal diseases. It also poses some fascinating questions about the evolutionary biology of this important group of pathogens. (shrink)

There is a world-wide debate at the moment about the appropriate role for the state in modern societies in the light of the world financial crisis. This book provides a comprehensive analysis and critique of Neo-liberal or economic liberal ideas on this issue.

A stimulating introduction to central issues of political theory, including liberty, rights and the state, and the claims of need and politics.

Widespread and lasting consensus has not been philosophy's fate. Indeed, one of philosophy's most striking features is its ability to accommodate “not only different answers to philosophical questions” but also “total disagreement on what questions are philosophical” (Rorty 1995, 58). It is therefore hardly surprising that philosophers' responses to this metaphilosophical predicament have been similarly varied. This article considers two recent diagnoses of philosophical diversity: Kornblith and Rescher (respectively) claim that taking philosophical disagreement seriously does not lead to metaphilosophical scepticism. (...) The article argues that their confidence is misplaced in so far as both wrongly assume that ordinary, first-order philosophical practice and second-order metaphilosophical reflection are separate enterprises. We can say that the universe consists of a substance, and this substance we will call “atoms,” or else we will call it “monads.” Democritus called it atoms. Leibniz called it monads. Fortunately, the two men never met, or there would have been a very dull argument. (Allen 1997, 171) When will philosophers learn to be less pretentious and arrogant in their claims? One would imagine that the philosophic experiences of twenty-five centuries would have taught them the fallacy of self-esteem! (Schilpp 1935, 233). (shrink)

It is possible to learn multiple layers of non-linear features by backpropagating error derivatives through a feedforward neural network. This is a very effective learning procedure when there is a huge amount of labeled training data, but for many learning tasks very few labeled examples are available. In an effort to overcome the need for labeled data, several different generative models were developed that learned interesting features by modeling the higher order statistical structure of a set of input vectors. One (...) of these generative models, the restricted Boltzmann machine (RBM), has no connections between its hidden units and this makes perceptual inference and learning much simpler. More significantly, after a layer of hidden features has been learned, the activities of these features can be used as training data for another RBM. By applying this idea recursively, it is possible to learn a deep hierarchy of progressively more complicated features without requiring any labeled data. This deep hierarchy can then be treated as a feedforward neural network which can be discriminatively fine-tuned using backpropagation. Using a stack of RBMs to initialize the weights of a feedforward neural network allows backpropagation to work effectively in much deeper networks and it leads to much better generalization. A stack of RBMs can also be used to initialize a deep Boltzmann machine that has many hidden layers. Combining this initialization method with a new method for fine-tuning the weights finally leads to the first efficient way of training Boltzmann machines with many hidden layers and millions of weights.

The value of rational choice theory for the social sciences has long been contested. It is argued here that, in the debate over its role, it is necessary to distinguish between claims that people maximise manifest payoffs, and claims that people maximise their utility. The former version has been falsified. The latter is unfalsifiable, because utility cannot be observed. In principle, utility maximisation can be adapted to fit any form of behaviour, including the behaviour of non-human organisms. Allegedly 'inconsistent' behaviour (...) is also impossible to establish without qualification. This utility-maximising version of rational choice theory has the character of a universal 'explanation' that can be made to 'fit' any set of events. This is a sign of weakness rather than strength. In its excessive quest for generality, utility-maximising rational choice theory fails to focus on the historically and geographically specific features of socio-economic systems. As long as such theory is confined to ahistorical generalities, then it will remain highly limited in dealing with the real world. Instead we have to consider the real social and psychological determinants of human behaviour. (shrink)

Mark Dooley has recently argued (principally against Simon Critchley) that the attempt to establish too strong a ‘connection’ between Jacques Derrida and Emmanuel Levinas not only distorts crucial disparities between their respective philosophies, it also contaminates Derrida’s recent work with Levinas’s inherent ‘political naivety’. In short, on Dooley’s reading, Levinas is only of ‘inspirational value’ for Derrida. I am not concerned with defending Critchley’s own reading of the ‘Derrida–Levinas connection’. My objective is rather to demonstrate, first, the way in which (...) Dooley’s argument hinges upon a misreading of Levinas and Derrida, and, second, why Derrida’s recent thinking is in fact fundamentally Levinasian. Key Words: contingency • guilt • Holocaust • hospitality • institutions • nature • suffering • third party • violence. (shrink)

In Culture and Value Wittgenstein remarks: ‘Thoughts that are at peace. That's what someone who philosophizes yearns for’. The desire for such conceptual tranquillity is a recurrent theme in Wittgenstein's work, and especially in his later ‘grammatical-therapeutic’ philosophy. Some commentators (notably Rush Rhees and C. G. Luckhardt) have cautioned that emphasising this facet of Wittgenstein's work ‘trivialises’ philosophy – something which is at odds with Wittgenstein's own philosophical ‘seriousness’ (in particular his insistence that philosophy demands that one ‘Go the bloody (...) hard way’). Drawing on a number of correlations between Wittgenstein's conception of philosophy and that of the Pyrrhonian Sceptics, in this paper I defend a strong ‘therapeutic’ reading of Wittgenstein, and show how this can be maintained without ‘trivialising’ philosophy.

Wittgenstein’s remarks on religious and magical practices are often thought to harbour troubling fideistic and relativistic views. Unsurprisingly, commentators are generally resistant to the idea that religious belief constitutes a ‘language‐game’ governed by its own peculiar ‘rules’, and is thereby insulated from the critical assessment of non‐participants. Indeed, on this fideist‐relativist reading, it is unclear how mutual understanding between believers and non‐believers (even between different sorts of believers) would be possible. In this paper I do three things: (i) show why (...) the fideist‐relativist reading of Wittgenstein is not wildly implausible (Sections 1–2); (ii) argue that, despite its initial plausibility, this reading fails to take into account Wittgenstein’s naturalism (Sections 3–4); and (iii) explain what sort of naturalism this is, and how it sheds light on Wittgenstein’s remarks on religious belief (Sections 5–6).

This article argues for four interrelated claims: Metaphilosophy is not one sub-discipline of philosophy, nor is it restricted to questions of methodology. Rather, metaphilosophical inquiry encompasses the general background conditions of philosophical practice. These background conditions are of various sorts, not only those routinely considered “philosophical” but also those considered biographical, historical, and sociological. Accordingly, we should be wary of the customary distinction between what is proper and merely contingent to philosophy. “What is philosophy?” is best understood as a practical (...) question concerning how members of different philosophical sub-communities identify what is pertinent to their respective activities and self-conceptions. Given –, understanding what philosophy is requires us to take more seriously the social-institutional dimension of contemporary philosophical practice. (shrink)

In 1981, after 20 years of teaching and writing philosophy, Derrida claimed that ‘less than ever’ did he ‘know what philosophy is’. Indeed, his ‘knowledge of what ... constitutes the essence of philosophy’ remained ‘at zero degree’. 1 These were not flippant remarks. Rather, Derrida’s avowed uncertainty is part of a more general metaphilosophical view; namely, that ‘Philosophy has a way of being at home with itself that consists in not being at home with itself’. 2 In this article I (...) will critically reconstruct and develop this view, paying particular attention to the ‘institutional’ dimension of contemporary philosophy.

Chomsky’s highly influential Syntactic Structures ( SS ) has been much praised its originality, explicitness, and relevance for subsequent cognitive science. Such claims are greatly overstated. SS contains no proof that English is beyond the power of finite state description (it is not clear that Chomsky ever gave a sound mathematical argument for that claim). The approach advocated by SS springs directly out of the work of the mathematical logician Emil Post on formalizing proof, but few linguists are aware of (...) this, because Post’s papers are not cited. Chomsky’s extensions to Post’s systems are not clearly defined, and the arguments for their necessity are weak. Linguists have also overlooked Post’s proofs of the first two theorems about effects of rule format restrictions on generative capacity, published more than ten years before SS was published.

First published in 1973 this volume demonstrates the interconnection between Hegel's political and metaphysical writings. This book provides a point of entry into Hegel's system of ideas. Condemned unread, and when read far too often misunderstood, Hegel's thought has once more begun to make its impact on contemporary ideas with many of today's most important social and political thinkers.

Following a brief preface, the second section of this paper discusses Mill's early reflections on the problem of how deductive inference can be illuminating. In the third section it is suggested that in his Logic Mill misconstrued the feature that the premises of a logically valid argument contain the conclusion as the ground of a charge that deductive proof is question-begging. The fourth section discusses the nature of the traditional petitio objection to syllogism, and the fifth shows that Mill had (...) a theory capable of answering it. The final section cites the confusion described in section 3 to explain why Mill nevertheless continued to think that syllogistic proofs beg the question. (shrink)

Simone Weil (1909-1943) was one of the most original philosophers & political thinkers of this century. Coming to Christianity late in her short life, she offered a refreshing creativity & a rare ability to confront theological complacencies. In introducing her writings & thoughts, this book emphasizes her never-ending search for truth, a search that epitomizes twentieth-century spirituality.

Medical humanities purchases its presence on the medical side of university campuses by adopting as its own the ends of medicine and medical ethics. It even justifies its presence by asserting promotion of those ends as an ethical imperative, most of all to improve the caring in medical care. As unobjectionable, even praiseworthy, as this imperative appears, it actually constrains the possibilities for interpersonal relationship in the context of medical practice. Development of those possibilities requires openness of self to the (...) existentially challenging ethical imperative to care also literally for nothing at all. (shrink)

Although the mathematization of nature is a distinctive and crucial feature of the emergence of modern science in the seventeenth century, this volume shows that it was a far more complex, contested, and context-dependent phenomenon than the received historiography has indicated.0.

According to Levinas, the history of western philosophy has routinely ‘assimilated every Other into the Same’. More concretely stated, philosophers have neglected the ethical significance of other human beings in their vulnerable, embodied singularity. What is striking about Levinas’ recasting of ethics as ‘first philosophy’ is his own relative disregard for non-human animals. In this article I will do two interrelated things: (1) situate Levinas’ (at least partial) exclusion of the non-human animal in the context of his markedly bleak conception (...) of ‘the state of nature’, and (2) drawing on Orwell, Wittgenstein and Gaita, argue that, despite his more positive evaluation of animality (specifically a dog named Bobby), Levinas is guided by a number of anthropomorphic prejudices; not least that the epithet ‘the animal’ can be used in the general singular.

In "The History of Sexuality", Foucault maintains that "Western man has become a confessing animal" (1990, 59), thus implying that "man" was not always such a creature. On a related point, Wittgenstein suggests that "man is a ceremonial animal" (1996, 67); here the suggestion is that human beings are, by their very nature, ritualistically inclined. In this paper I examine this crucial difference in emphasis, first by reconstructing Foucault's "genealogy" of confession, and subsequently by exploring relevant facets of Wittgenstein's later (...) thinking. While there are significant correlations between Foucault and Wittgenstein, an important disparity emerges in relation to the question of the "natural." By critically analyzing this, I show how Wittgenstein's minimal naturalism provides an important corrective to Foucault's more extravagant claims. By implication, we see why any radical relativist, historicist, and/or constructivist position becomes untenable on Wittgensteinian grounds, even though Wittgenstein himself is often read as promoting such views.

The Spanish philosopher Miguel de Unamuno and the American social scientist Ernest Becker see death as humanity’s fundamental anxiety. My essay explores the ethical ramifications attendant upon making that anxiety a well-spring of human activity. More specifically, I am interested in humanity’s effort to escape death via the secular milieu of social remembrance. Does such an effort produce a vista where the other exhibits an intrinsic value? Alternatively, does the other become a mere means in light of one’s project of (...) self-preservation? Pursuing such questions, this reflection will explore both positive and negative responses. It will take up the Columbine school shootings in reference to the latter and a notion of protest with regard to the former. The treatise will culminate with a discussion of Unamuno’s ethics of irreplaceability and its potential to engender a universal human respect while also endorsing one’s commitment to her concrete individuality.

How would a liberation theologian respond to Marx’s famous critique that religious belief and, even more specifically, a hope for heaven is “the opium of the people”? I utilize the conceptual resources found within the work of liberation theologians Gustavo Gutiérrez, Enrique Dussel, and Jon Sobrino to argue that a belief in heaven is able to constitute a protest against oppressed persons’ present hell. To strengthen the connection between a believer’s heavenly hope and a commitment to worldly struggle, I examine (...) how the hope must be conceived as the completion and fulfillment of a process of temporal transformation.

La création d’un système de santé public a été l’un des éléments clés de la Révolution tranquille dans les années 1960 au Québec. Toutefois, le développement de nouveaux traitements et de nouvelles technologies, en particulier des produits pharmaceutiques, ont fait naître un nouveau débat sur la gestion de notre système de santé. En se basant sur une analyse récente des valeurs libérales dans la société québécoise par Claude Ryan, l’auteur souligne l’importance que le gouvernement doit accorder à ces valeurs dans (...) la modernisation de notre système de santé. À la lumière des recommandations présentées par la commission Clair au provincial et par la commission Romanow au fédéral, la situation se prête bien à une modernisation du système de soins au Québec. Les valeurs libérales ont fourni une base au système de santé public ; elles sont plus pertinentes qu’elles ne l’ont jamais été alors que le débat sur notre système de santé est engagé. (shrink)

On Civic Republicanism explores the enduring relevance of the ancient concepts of republicanism and civic virtue to modern questions about political engagement and identity.".

There are long-standing doubts about whether data from subjective scales—for instance, self-reports of happiness—are cardinally comparable. It is unclear how to assess whether these doubts are justified without first addressing two unresolved theoretical questions: how do people interpret subjective scales? Which assumptions are required for cardinal comparability? This paper offers answers to both. It proposes an explanation for scale interpretation derived from philosophy of language and game theory. In short: conversation is a cooperative endeavour governed by various maxims (Grice 1989); (...) because subjective scales are vague and individuals want to make themselves understood, scale interpretation is a search for a focal point (Schelling 1960). A specific focal point it hypothesised; if this hypothesis is correct, subjective data will be cardinally comparable. Four individually necessary and jointly sufficient conditions for cardinal comparability are specified. The paper then argues this hypothesis can be empirically be tested, makes an initial attempt to do so using subjective well-being data, and concludes it is supported. Numerous areas for further research are identified including, at the end of the paper, how certain tests could be used to ‘correct’ subjective data if they are not cardinal. (shrink)

This article examines the issues raised by religious adherents’ wish to express their beliefs in the public domain through, for example, their modes of dress, their performance of public roles, and their response to homosexuality. It considers on what grounds religion might merit special treatment and how special that treatment should be. A common approach to these issues is through the notion of religious identity, but both the idea of religious identity and its use to ground claims against others prove (...) deeply problematic. An alternative and more productive approach is through the notion of harm. People should enjoy the freedom to express their religious convictions subject to the harm principle, but harm should include the undermining of people’s status as free and equal citizens. The article concludes by considering the grounds upon which this alternative approach might recognize religion as special and might justify giving an overriding status to civic equality. (shrink)
