Les sociétés démocratiques sont confrontées à l'émergence d'enjeux environnementaux décisifs qui concernent tant les modes de production, d'échange et de consommation que l'habitat, les transports, l'agriculture, l'industrie et même nos modes de vie. La prise en charge de ces enjeux ne saurait s'opérer simplement par des mesures ponctuelles ou locales. Elle doit aujourd'hui être repensée la temporalité de l'action politique, confrontée à une urgence qui ne cessera de s'accroître dans les prochaines années.

Of all the demands that mathematics imposes on its practitioners, one of the most fundamental is that proofs ought to be correct. It has been common since the turn of the twentieth century to take correctness to be underwritten by the existence of formal derivations in a suitable axiomatic foundation, but then it is hard to see how this normative standard can be met, given the differences between informal proofs and formal derivations, and given the inherent fragility and complexity of (...) the latter. This essay describes some of the ways that mathematical practice makes it possible to reliably and robustly meet the formal standard, preserving the standard normative account while doing justice to epistemically important features of informal mathematical justification.

The epsilon calculus is a logical formalism developed by David Hilbert in the service of his program in the foundations of mathematics. The epsilon operator is a term-forming operator which replaces quantifiers in ordinary predicate logic. Specifically, in the calculus, a term εx A denotes some x satisfying A(x), if there is one. In Hilbert's Program, the epsilon terms play the role of ideal elements; the aim of Hilbert's finitistic consistency proofs is to give a procedure which removes such terms (...) from a formal proof. The procedures by which this is to be carried out are based on Hilbert's epsilon substitution method. The epsilon calculus, however, has applications in other contexts as well. The first general application of the epsilon calculus was in Hilbert's epsilon theorems, which in turn provide the basis for the first correct proof of Herbrand's theorem. More recently, variants of the epsilon operator have been applied in linguistics and linguistic philosophy to deal with anaphoric pronouns. (shrink)

“Now, in calm weather, to swim in the open ocean is as easy to the practised swimmer as to ride in a spring-carriage ashore. But the awful lonesomeness is intolerable. The intense concentration of self in the middle of such a heartless immensity, my God! who can tell it? Mark, how when sailors in a dead calm bathe in the open sea—mark how closely they hug their ship and only coast along her sides.” (Herman Melville, Moby Dick, Chapter 94).

In 1837, Dirichlet proved that there are infinitely many primes in any arithmetic progression in which the terms do not all share a common factor. We survey implicit and explicit uses ofDirichlet characters in presentations of Dirichlet’s proof in the nineteenth and early twentieth centuries, with an eye toward understanding some of the pragmatic pressures that shaped the evolution of modern mathematical method.

Proponents of evidence-based medicine and some philosophers of science seem to agree that knowledge of mechanisms can help solve the problem of applying results of controlled studies to target populations (‘the problem of extrapolation’). We describe the problem of extrapolation, characterize mechanisms, and outline how mechanistic knowledge might be used to solve the problem. Our main thesis is that there are four often overlooked problems with using mechanistic knowledge to solve the problem of extrapolation. First, our understanding of mechanisms is (...) often (and arguably, likely to remain) incomplete. Secondly, knowledge of mechanisms is not always applicable outside the tightly controlled laboratory conditions in which it is gained. Thirdly, mechanisms can behave paradoxically. Fourthly, as Daniel Steel points out, using mechanistic knowledge faces the problem of the ‘extrapolator’s circle’. At the same time, when the problems with mechanistic knowledge have been addressed, such knowledge can and should be used to mitigate (nothing can entirely solve) the problem of extrapolation.

Koonin, in an article in this issue, claims that CRISPR–Cas systems are mechanisms for the inheritance of acquired adaptive characteristics, and that the operation of such systems comprises a “Lamarckian mode of evolution.” We argue that viewing the CRISPR–Cas mechanism as facilitating a form of “directed mutation” more accurately represents how the system behaves and the history of neoDarwinian thinking, and is to be preferred.

Contribution to a symposium on Keith DeRose's book, The Case for Contextualism: Knowledge, Skepticism, and Context.

Existing accounts of the Rule of Law are inadequate and require fleshing out. The main value of the ideal of rule of law for liberal political theory lies in the notion of predictability, which is essential to individual autonomy. The author examines this connection and argues that conservative theories of rule of law claim too much. Liberal theory equates the rule of law with legality, which is only one of the elements necessary for a just social order.

This is a three-part study and defense of the idea of basic human equality. (This is the idea that humans are basically one another's equals, as opposed to more derivative theories of the dimensions in which we ought to be equal or the particular implications that equality might have for public policy.) Part (1) of the paper examines the very idea of basic equality and it tries to elucidate it by considering what an opponent of basic human equality (e.g. a (...) philosophical racist) might hold. It explores the idea of there being no morally significant fundamental divisions among humans (of the kind that some people insist on as between humans and others animals). Part (2) considers whether basic human equality must be based on some descriptive similarity among us (naturalistic or metaphysical); it considers the positions of a number of thinkers who have denied this. Part (3) considers John Rawls's conception of basic equality in terms of range properties. (Being in Ohio is a range property; Columbus and Cincinnati are both equally in Ohio even though even though Columbus is in the center of the state, while Cincinnati is just over the river from Kentucky.) It explores the application of this Rawlsian idea to the descriptive properties that might be thought relevant to human equality. This three part paper is a rather technical philosophical exploration. And it is just a beginning; we need much more work on the idea of basic equality. Some of the energy that has gone into discussions of equality as a policy aim (e.g. in the Dworkin/Sen literature or in the literature surrounding Rawls's Difference Principle) needs to be devoted to this more fundamental conception.

In earlier articles, the author developed what is known as the "Supersession Thesis," asserting that historic injustice may be overtaken by changes in circumstances so that a situation that was unjust when it was brought about may coincide with what justice requires at a later time. The Supersession Thesis was developed initially as a tool for considering historic injustice suffered by indigenous peoples in the European settlement of countries like Australia, Canada, New Zealand, and the United States. In this paper, (...) the author explores the application of the Supersession Thesis to issues about the Palestinian right of return and also to Israeli settlements in the Occupied Territories. The paper argues that, while it is not unthinkable that the Supersession Thesis might eventually legitimize the settlements and undermine the Palestinian right of return, there is no guarantee that this will happen. The application of the Supersession Thesis does not depend on the passage of time, but on changes in circumstances that a theory of justice makes relevant. Many of the circumstances that make the Supersession Thesis relevant to the post-colonial situations described do not apply in the Israeli situation. Nevertheless, it is worth considering the possibility of applying the Supersession Thesis in this case, because it enables us to assess the merits of the Thesis more sharply in relation to injustice that is taking place now, as opposed to injustice that took place in the nineteenth century.

st of these lectures, I present a conception of dignity that preserves its ancient association with rank and station, and a conception of human dignity that amounts to a generalization of high status across all human beings. The lectures argue that this provides a better understanding of human dignity and of the work it does in theories of rights than the better-known Kantian conception. The second lecture focuses particularly on the importance of dignity - understood in this way - as (...) a status defining a person's relation to law: their presentation as persons capable of self-applying the law, capable of presenting and arguing a point of view, and capable of responding to law's demands without brute coercion. Together the two lectures also illuminate the relation between dignity conceived as the ground of rights and dignity conceived as the content of rights; they also illuminate important ideas about dignity as noble bearing and dignity as the subject of a right against degrading treatment; and they help us understand the sense in which dignity is better conceived as a status than as a kind of value.

Do property entitlements define the moral environment in which rights to well-being are defined, or do rights to well-being define the moral environment in which property entitlements are defined? Robert Nozick argued for the former alternative and he denied that any serious attempt had been made to state the latter alternative (what he called “the ‘reverse’ theory”). I actually think John Locke's approach to property can be seen as an instance of the “reverse” theory. And Nozick's can too, inasmuch as (...) it shares a number of features with the Lockean approach. But my paper is not intended as a criticism of Nozick; on the contrary, it acknowledges the integrity and the importance of his insistence that welfare, property, and justice be integrated into a single theory with clearly established priorities.

The ethical and political dilemmas raised byInformation and Communication Technology (ICT)have only just begun to be understood. Theimpact of centralised data collection, masscommunication technologies or the centrality ofcomputer technology as a means of accessingimportant social institutions, all poseimportant ethical and political questions. As away of capturing some of these effects I willcharacterise them in terms of the type of powerand, more particularly, the ‘Power-over’ peoplethat they exercise. My choice of thisparticular nomenclature is that it allows us todescribe, firstly, how specific (...) technologiesoperate and second, exactly what sorts ofconstraints they impose on people. The reasonfor this focus has to do with a further aim ofthe essay, which is to intervene in aparticular type of debate that is often hadaround the appropriate use and scope oftheories of power that are employed in thinkingabout ICT, especially those theories associatedwith the work of Michel Foucault. There isconsiderable use of his work in computerethics, but my claim will be that despite theproductive uses of his work in the areas ofsurveillance, for instance, it does not exhaustthe larger potential of his work on power and,in part, `government.' I will argue that inorder to properly understand the politicalimpact of some aspects of ICT, especially thedigital divide, one needs an account of howpower operates that includes more traditionaltypes of power-over. To the extent that I willdeal with these concerns, the paper is both acontribution to debates about the nature andscope of Foucault's theory of power and to theissue of the effects of the digital divide.

The paper argues that dreams consist partly in an awareness or experience of the conceptual fabric of our existence. Since what we mean by reality is intimately tied to the concepts given in our experience, dreams are therefore also partly an awareness of the fabric of what we mean by being itself and in general, that is, by objective as well as subjective reality. Further, the paper argues that this characteristic of dreams accounts for several other, more specific aspects of (...) dreams and their possible interpretation, and that it allows us to see how these aspects are related to each other. These more specific aspects are the peculiar types of conceptual or logical relations and transitions that occur within dreams, dreams’ distinctive feeling texture, and some dimensions of the grounds and nature of suitable methods of interpreting dreams.

Literary pedagogy occupied a privileged place in Bourdieu's early work on education insofar as he saw it as exemplifying in unconscious mode socially segregational dynamics. Bourdieu's expressly ‘reductionist’ critique was uncannily mirrored, however, by the spread of more economically instrumental approaches to education. Bourdieu's engagement with these led him to develop a fuller apprehension of literature. Yet while the conceptual apparatus he developed can allow the genesis of a literary work in its socio-historical complexity to be grasped more fully, its (...) framing poses significant problems of its own. In particular, its ‘hypercontextualizing’ injunctions risk stifling ordinary reading practices and the practical pedagogy of canon-formation. Bourdieu's actual practice with literary materials is not bound by these injunctions. His transepochal ‘collaboration’ with Blaise Pascal, for example, takes place through the insinuation of decontextualised shards of thought into his own writing. The teachings of literature exceed in various ways their scientific framing. (shrink)

In Utopies et devenirs deleuziens (Utopias and Deleuzian becomings), Philippe Mengue reflects on the complex and sometimes problematic relationship between the French philosopher Gilles Deleuze and the concept of utopia. As argued by Mengue, Deleuze’s position on utopia is distinctive and can bring interesting insights into contemporary discussions on both philosophy and utopias. While Mengue is not a specialist of utopias, he certainly presents a respectable expertise on Deleuze and his thought, making this book an original contribution to the field. (...) Mengue’s project emanates from lectures given at L’Université Populaire d’Avignon in 2008. Utopies et devenirs deleuziens targets a rather wide audience of .. (shrink)

The notion of a function from ℕ to ℕ defined by recursion on ordinal notations is fundamental in proof theory. Here this notion is generalized to functions on the universe of sets, using notations for well orderings longer than the class of ordinals. The generalization is used to bound the rate of growth of any function on the universe of sets that is Σ1-definable in Kripke–Platek admissible set theory with an axiom of infinity. Formalizing the argument provides an ordinal analysis.

Summary. A constructive realizablity interpretation for classical arithmetic is presented, enabling one to extract witnessing terms from proofs of 1 sentences. The interpretation is shown to coincide with modified realizability, under a novel translation of classical logic to intuitionistic logic, followed by the Friedman-Dragalin translation. On the other hand, a natural set of reductions for classical arithmetic is shown to be compatible with the normalization of the realizing term, implying that certain strategies for eliminating cuts and extracting a witness from (...) the proof of a 1 sentence are insensitive to the order in which reductions are applied.

We show that the theory ATR0 is equivalent to a second-order generalization of the theory $\widehat{ID}_{<\omega}$. As a result, ATR0 is conservative over $\widehat{ID}_{<\omega}$ for arithmetic sentences, though proofs in ATR0 can be much shorter than their $\widehat{ID}_{<\omega}$ counterparts.

In this paper, we report results from experiments in which people read conversational arguments and then judge the convincingness of each claim and the individual speakers' burden of proof. The results showed an "anti-primacy" effect: People judge the speaker who makes the first claim as having greater burden of proof. This effect persists even when each speaker's claims are rated equally convincing. We also find that people rate claims less convincing when they appear in the first part of an argument (...) than when they appear in isolation. (shrink)

This article explores the debate about the virtues and otherwise of luxury in French eighteenth- and nineteenth political thought. I begin by contrasting the views of Jean-Jacques Rousseau and Jean-Francois Melon. In view of the manner in which this argument was developed by Montesquieu, Diderot, Saint-Lambert, and others, I argue that debates about luxury continued into and beyond the French Revolution of 1789. Then, by looking at the writings of Jean-Baptiste Say and Destutt de Tracy the article demonstrates the coninued (...) prominence of debates about luxury in the early years of the nineteenth century and the enduring nature of the arguments posed by Rousseau against immoderate wealth amongst republicans. It concludes by referring to discussions of luxury in the Second Empire. (shrink)

Why are people attracted to conspiracy theories? This essay conceives of conspiratorial motivation as an aesthetic phenomenon. To defend this account, I offer a coarse-grained taxonomy of contemporary motivational hypotheses that have been proposed to answer this question, describing their strengths and weaknesses. Next, I offer an aesthetic account of conspiratorial consumption; I argue that people’s preference for conspiratorial narratives is the product of a taste for a particular kind of story. To clarify the approach, I show how aesthetic appreciation (...) is often confused with epistemic evaluation, leading the conspiracy theorist to believe she is involved in epistemic practice instead of aesthetic practice. I then describe the genre of conspiracy theorizing, explaining how my proposed genre account makes sense of several puzzles about conspiratorial consumption. The essay concludes by suggesting that the genre account offers a unique mode of engagement with conspiracy theorists that might be employed in order to profitably dialogue with those who hold these fringe and often dangerous beliefs.

If unremunerated blood donors are willing to participate, and if the use of them is economical from the perspective of those collecting blood, I can see no objection to their use. But there seems to me no good reason, moral or practical, why they should be used. The system of paid plasmapheresis as it currently operates in the United States and in Canada would seem perfectly adequate, and while there may always be ways in which the safety and efficiency of (...) supply could be increased, there seems no reason whatever to think that there would be an improvement if the current system changed so as to rely entirely on unpaid donors. Further, given the adequacy of paid plasmapheresis, I could see no problem if the collection of whole blood were to take place on a similar, fully-commercial, basis. Such a view is controversial. To argue for it, this paper offers just one strand in a complex argument: a critique of Richard Titmuss’s Gift Relationship, which holds an iconic position in the critical literature on the paid provision of blood. As I conclude: all told, there seems no good basis for rejecting supply of whole blood for money—let alone the supply of blood plasma. (shrink)

This article looks at the problems of the co-determination of the political within western metaphysics and political reflection, and considers solutions that are figured in terms of failure and incompletion. The focus is on the relation of the political to political modernity, its defenders and attackers, and those who seek to overcome the opposition.

Awareness of boundary, both physical and mental, is seen as the beginning of perception. In any account of the world, therefore, boundary must be a ubiquitous component. In sharp contrast, accounts of God within the Christian tradition commonly have proceeded by the affirmation that God is above and beyond boundary as infinite, timeless, and simple. To overcome this “problem of transcendence,” of how such a God can relate to such a world, an eight-term grammar of boundary is developed to demonstrate (...) how God as Trinity can properly be held to be without boundary yet constitute the ground of a bounded world. This leads to a way of granting theological significance to the origin and development of life. Life is seen to exist in dynamic, intentional relationships between context (“outside”) and intext (“inside”) across permeable boundaries through which an exchange of resources and information takes place for the sake of self-continuation. Comprehending life's distinctive utilization of boundary in terms of the grammar developed here enables life to be seen not only as a vestige of the Trinity but also, precisely because of this, as a sign and parable of redemption.

A resilient issue in research ethics is whether and when a placebo-controlled trial is justified if it deprives research subjects of a recognized treatment. The clinicians' moral duty to provide the best available care seems to require the use of ‘active’ controlled trials that use an established treatment as a control whenever such a therapy is available. In another regard, ACTs are supposedly methodologically inferior to PCTs. Hence, the moral duty of the clinical researcher to use the best methods will (...) favor PCTs. In this target article, I analyze the three reasons for believing that ACTs are inferior to PCTs namely: 1) ACTs lack ‘assay sensitivity’; 2) ACTs do not measure absolute effect size; and 3) ACTs require more participants; and I contend that none are acceptable. Consequently the tension between clinical and research ethics dissolves: the moral duty of the clinician to avoid PCTs is unopposed by methodological considerations. (shrink)

This article seeks to identify the political and ideological dimensions of the contemporary presence of information technology or infotech. This presence is experienced as the progressive unfolding of technology as the logic of the social itself. Rather than approaching these dimensions through their reduction to a ground, a symbolic totality or a specific interest, and argument is constructed from Laclau and Mouffe's concept of `antagonism' in conjunction with Claude Lefort's notion of `invisible ideology'. This gives the argument the advantage of (...) relating the constitution of ideology to a historically specific political formation, instead of positing a timeless relation to the constitution of an abstract subject as the ground of an explanation. The argument is that insofar as information technology appears as a substance that absorbs the dynamic of community, which I call autotechnopoiesis, then ideology constructs the identity of this space with itself. The political is understood as the failure of this self-presence. In conclusion, these issues are located in terms of the governmentality of the `performative state' which seeks the recruitment of subjects to the `promotion of the social' through an investment in the banality of communication.

This paper proposes a principle for adjudicating conflicts between estranged couples over whether the frozen embryos they earlier created together ought to be gestated or destroyed. I argue that the fate of the embryos ought to be determined by the party who would be most harmed by having his or her preferences overruled. But I also claim that, when embryos are destroyed against the opposition of one of their co-creators, the individual at whose behest this was done owes compensation to (...) his disappointed opposite number, in an amount that reflects the harm accruing to the latter as a result of the termination of the procreative project.

This paper explores the tension between two views attributed to Plato: 1) that every person in a just society must fulfil his function, and 2) justice requires philosophical wisdom. It is argued that is not Plato’s view in Republic, and that this can be seen as early as Book II.
