Nanomaterials are handled in global value chains for many different products, albeit not always recognisable as nanoproducts. The global market for nanomaterials faces an uncertain future, as the international dialogue on regulating nanomaterials is still ongoing and risk assessment data are being collected. At the same time, regulators and civil society organisations complain about a lack of transparency about the presence of nanomaterials on the market. In the project on Sustainable Nanotechnologies, a Decision Support System has been developed, primarily for (...) confidential use by risk and sustainability managers inside a company or consortium. In this article, we formulate a scenario concerning a potential role for an open access decision support system in negotiations on international agreements regulating trade in nanomaterials. The scenario includes design rules for decision support systems as well as procedures for use of such a system in stakeholder dialogue and policy-making on governance of these and other emerging technologies. This article incorporates analysis of results of stakeholder engagement on nanomaterials as well as literature and internet sources suggested by these stakeholders. (shrink)

Cultural evolution studies are characterized by the notion that culture evolves accordingly to broadly Darwinian principles. Yet how far the analogy between cultural and genetic evolution should be pushed is open to debate. Here, we examine a recent disagreement that concerns the extent to which cultural transmission should be considered a preservative mechanism allowing selection among different variants, or a transformative process in which individuals recreate variants each time they are transmitted. The latter is associated with the notion of “cultural (...) attraction”. This issue has generated much misunderstanding and confusion. We first clarify the respective positions, noting that there is in fact no substantive incompatibility between cultural attraction and standard cultural evolution approaches, beyond a difference in focus. Whether cultural transmission should be considered a preservative or reconstructive process is ultimately an empirical question, and we examine how both preservative and reconstructive cultural transmission has been studied in recent experimental research in cultural evolution. Finally, we discuss how the relative importance of preservative and reconstructive processes may depend on the granularity of analysis and the domain being studied. (shrink)

This paper offers a new account of how structural rationality, or coherence, is normative. The central challenge to the normativity of coherence – which I term the problem of “making space” for the normativity of coherence – is this: if considerations of coherence matter normatively, it is not clear how we ought to take account of them in our deliberation. Coherence considerations don’t seem to show up in reasoning about what to believe, intend, desire, hope, fear, and so on; moreover, (...) they seem awkward to take account of alongside more “substantive” considerations about the merits of such attitudes. I aim here to solve this problem, and in so doing to offer the aforementioned new account of how coherence is normative. On the view I defend, which I call the Reasons-to-Structure-Deliberation model, considerations of coherence constitute reasons for structuring deliberation in certain ways: more particularly, to treat incoherent combinations of attitudes as off-limits, and so to focus one’s deliberation on choosing between the coherent combinations. (shrink)

There are at least two different aspects of our rational evaluation of agents’ doxastic attitudes. First, we evaluate these attitudes according to whether they are supported by one’s evidence (substantive rationality). Second, we evaluate these attitudes according to how well they cohere with one another (structural rationality). In previous work, I’ve argued that substantive and structural rationality really are distinct, sui generis, kinds of rationality – call this view ‘dualism’, as opposed to ‘monism’, about rationality – by arguing that the (...) requirements of substantive and structural rationality can come into conflict. In this paper, I push the dialectic on this issue forward in two main ways. First, I argue that the most promising ways of resisting the diagnosis of my cases as conflicts still end up undermining monism in different ways. Second, supposing for the sake of argument that we should understand the cases as conflicts, I address the question of what we should do when such conflicts arise. I argue that, at least in a prominent kind of conflict case, the coherence requirements take precedence over the evidential requirements. (shrink)

This article puts pressure on moral motivational internalism and rejects normative motivational internalism by arguing that we should be aesthetic motivational externalists. Parallels between aesthetic and moral normativity give us new reason to doubt moral internalism. I address possible disanalogies, arguing that either they fail, or they succeed, but aren’t strong enough to underwrite a motivational difference between the domains. Furthermore, aesthetic externalism entails normative externalism, providing further presumptive evidence against moral internalism. I also make the case that, regardless of (...) these particular conclusions, examining different normative domains alongside each other is a fruitful way to move debates forward. (shrink)

The second premise of the Kalām cosmological argument, as defended by William Lane Craig, has two supporting arguments; the Hilbert’s Hotel argument and the suc.

Interdisciplinary work on the nature of borders and society has enriched and complicated our understanding of democracy, community, distributive justice, and migration. It reveals the cognitive bias of methodological nationalism, which has distorted normative political thought on these topics, uncritically and often unconsciously adapting and reifying state‐centered conceptions of territory, space, and community. Under methodological nationalism, state territories demarcate the boundaries of the political; society is conceived as composed of immobile, culturally homogenous citizens, each belonging to one and only one (...) state; and the distribution of goods is analyzed according to a stark opposition between the domestic and the international. This article describes how methodological nationalism has shaped central debates in political philosophy and introduces recent work that helps dispel this bias. (shrink)

That biology provides explanations is not open to doubt. But how it does so must be a vexed question for those who deny that biology embodies laws or other generalizations with the sort of explanatory force that the philosophy of science recognizes. The most common response to this problem has involved redefining law so that those grammatically general statements which biologists invoke in explanations can be counted as laws. But this terminological innovation cannot identify the source of biology's explanatory power. (...) I argue that because biological science is historical, the problem of biological explanation can be assimilated to the parallel problem in the philosophy of history, and that the problem was solved by Carl Hempel. All we need to do is recognize that the only laws that biology—in all its compartments from the molecular onward—has or needs are the laws of natural selection. (shrink)

According to the subjective view of lying, speakers can lie by asserting a true proposition, as long as they believe this proposition to be false. This view contrasts with the objective view, according to which lying requires the actual falsity of the proposition asserted. The aim of this paper is to draw attention to pairs of assertions that differ only in intuitively redundant content and to show that such pairs of assertions are a reason to favour the subjective view of (...) lying over the objective one.

We present a plural logic that is as expressively strong as it can be without sacrificing axiomatisability, axiomatise it, and use it to chart the expressive limits set by axiomatisability. To the standard apparatus of quantification using singular variables our object-language adds plural variables, a predicate expressing inclusion (is/are/is one of/are among), and a plural definite description operator. Axiomatisability demands that plural variables only occur free, but they have a surprisingly important role. Plural description is not eliminable in favour of (...) quantification; on the contrary, quantification is definable in terms of it. Predicates and functors (function signs) can take plural as well as singular terms as arguments, and both many-valued and single-valued functions are expressible. The system accommodates collective as well as distributive predicates, and the condition for a predicate to be distributive is definable within it; similarly for functors. An essential part of the project is to demonstrate the soundness and completeness of the calculus with respect to a semantics that does without set-theoretic domains and in which the use of settheoretic extensions of predicates and functors is replaced by the sui generis relations and functions for which the extensions were at best artificial surrogates. Our metalanguage is designed to solve the difficulties involved in talking plurally about individuals and about the semantic values of plural items. (shrink)

It is commonly assumed that ‘ought’ implies ‘can’, that is, that if we ought to do something, then it must be the case that we can do it. It is a frequent quip about this thesis that any account must specify three things: what is meant by the ‘ought’, what is meant by the ‘implies’, and what is meant by the ‘can’. Something is missed, though, when we state the thesis in its shortened, three-word form. We overlook what it means (...) to do something. It is, I think, not mere coincidence that nobody has discussed this issue: It is very difficult to specify what it means to do something in the relevant sense. This paper is devoted to fleshing out one way of doing something that is a problem for the thesis. (shrink)

In this paper, we present two variants of Peirce’s Triadic Logic within a language containing only conjunction, disjunction, and negation. The peculiarity of our systems is that conjunction and disjunction are interpreted by means of Peirce’s mysterious binary operations Ψ and Φ from his ‘Logical Notebook’. We show that semantic conditions that can be extracted from the definitions of Ψ and Φ agree (in some sense) with the traditional view on the semantic conditions of conjunction and disjunction. Thus, we support (...) the conjecture that Peirce’s special interest in these operations is due to the fact that he interpreted them as conjunction and disjunction, respectively. We also show that one of our systems may serve as a suitable base for an interesting implicative expansion, namely the connexive three-valued logic by Cooper. Sound and complete natural deduction calculi are presented for all systems examined in this paper. (shrink)

This review of recent work in the philosophy of science motivated by a commitment to 'naturalism' begins by identifying three key axioms and one theorem shared by philosophers thus self-styled. Owing much to Quine and Ernest Nagel, these philosophers of science share a common agenda with naturalists elsewhere in philosophy. But they have disagreed among themselves about how the axioms and the theorems they share settle long-standing disputes in the philosophy of science. After expounding these disagreements in the work of (...) Boyd, Giere, Laudan, and Kitcher, I argue that naturalism needs to look for more than mere consistency in its foundations. (shrink)

The fundamental thesis of David Lewis's "Parts of Classes" is that the nonempty subsets of a set are mereological parts of it. This paper shows that Lewis's considerations in favor of this thesis are unpersuasive. First, common speech provides no support. Second, the formal analogy between mereology and the Boolean algebra of sets can be explained without accepting the thesis. Third, it is very doubtful that the thesis is fruitful. Certainly, Lewis's claim that it helps us understand set theory is (...) unwarranted. (shrink)

How we evaluate things and what we desire are closely connected. In typical cases, the things we desire are things that we evaluate as good or desirable. According to evaluation theories of desire, this connection is a very tight one: desires are evaluations of their objects as good or as desirable. There are two main varieties of this view. According to Doxastic Evaluativism, to desire that p is to believe or judge that p is good. According to Perceptual Evaluativism, to (...) desire that p is to perceive p as being good (or for p to seem good). The present paper poses a puzzle for such views. The puzzle should be familiar to theorists interested in the normativity and metaphysics of the emotions, but I am unaware of its application to desire. The aim of the present paper is to present the puzzle as it applies to desire, which should be of independent interest, but I also hope that by shining a light on the puzzle in this domain, we might put ourselves in a better position to offer a solution in all cases. At the end of the paper, I gesture towards a promising way ahead that departs from relying on contradictory contents. (shrink)

If a potential person would have a good life if he were to come into existence, can we coherently regard his coming into existence as better for him than his never coming into existence? And can we regard the situation in which he never comes into existence as worse for him? In this paper, we argue that both questions should be answered affirmatively. We also explain where prominent arguments to differing conclusions go wrong. Finally, we explore the relevance of our (...) answers to issues in population ethics. (shrink)

The revival of classical liberal thought has reignited a debate about economic freedom and social justice. Classical liberals claim to defend expansive economic freedom, while their critics wish to restrict this freedom for other values. However, there are two problems with the role ‘economic freedom’ plays in this debate: inconsistency in the use of the concept and indeterminacy with respect to its definition. Inconsistency in the use of the concept ‘freedom’ has mistakenly made a certain kind of ‘left-wing’ critique of (...) poverty, and of markets generally, appear to be a concern with inequality in means to enjoy freedom, not with freedom itself. Indeterminacy about which beings and doings the basic liberties protect misrepresents the left-wing position as about something other than economic freedom. Inconsistency and indeterminacy lead to artificial narrowness in current debates and to a failure to see that disagreement is based not just on moral differences but also on conceptual confusion. This confusion leads both classical liberals and their critics to claim more than they may legitimately do, and to ignore a position that accepts the standard of definition of freedom but arrives at different institutional conclusions about what secures that freedom.

This book provides an in-depth introduction to, and analysis of, the issues relating to the implementation of the recent Responsibility to Protect principle in international relations The Responsibility to Protect has come a long way in a short space of time. It was endorsed by the General Assembly of the UN in 2005, and unanimously reaffirmed by the Security Council in 2006 and 2009. UN Secretary-General Ban Ki-moon has identified the challenge of implementing RtoP as one of the cornerstones of (...) his Secretary-Generalship. The principle has also become part of the working language of international engagement with humanitarian crises and has been debated in relation to almost every recent international crisis âe" including Sudan, Sri Lanka, Myanmar, Georgia, the Democratic Republic of Congo, Darfur and Somalia. Concentrating mainly on implementation challenges including the prevention of genocide and mass atrocities, strengthening the UNâes capacity to respond, and the role of regional organizations, this book introducing readers to contemporary debates on R2P and provides the first book-length analysis of the implementation agenda. The book will be of great interest to students of the responsibility to protect, humanitarian intervention, human rights, foreign policy, security studies and IR and politics in general. (shrink)

Physicalism and antireductionism are the ruling orthodoxy in the philosophy of biology. But these two theses are difficult to reconcile. Merely embracing an epistemic antireductionism will not suffice, as both reductionists and antireductionists accept that given our cognitive interests and limitations, non-molecular explanations may not be improved, corrected or grounded in molecular ones. Moreover, antireductionists themselves view their claim as a metaphysical or ontological one about the existence of facts molecular biology cannot identify, express, or explain. However, this is tantamount (...) to a rejection of physicalism and so causes the antireductionist discomfort. In this paper we argue that vindicating physicalism requires a physicalistic account of the principle of natural selection, and we provide such an account. The most important pay-off to the account is that it provides for the very sort of autonomy from the physical that antireductionists need without threatening their commitment to physicalism.

There is only one physically possible process that builds and operates purposive systems in nature: natural selection. What it does is build and operate systems that look to us purposive, goal directed, teleological. There really are not any purposes in nature and no purposive processes ether. It is just one vast network of linked causal chains. Darwinian natural selection is the only process that could produce the appearance of purpose. That is why natural selection must have built and must continually (...) shape the intentional causes of purposive behavior. Fodor’s argument against Darwinian theory involves a biologist’s modus tollens which is a cognitive scientist’s modus ponens. Assuming his argument is valid, the right conclusion is not that Darwin’s theory is mistaken but that Fodor’s and any other non-Darwinian approaches to the mind are wrong. It shows how getting things wrong in the philosophy of biology leads to mistaken conclusions with the potential to damage the acceptance of a theory with harmful consequences for human well-being. Fodor has shown that the real consequence of rejecting a Darwinian approach to the mind is to reject a Darwinian theory of phylogenetic evolution. This forces us to take seriously a notion that otherwise would not have much of a chance: that when it comes to the nature of mental states, indeterminacy rules. This is an insight that should have the most beneficial impact on freeing cognitive neuroscience from demands on the adequacy of its theories that it could never meet. (shrink)

The view that moods are dispositions has recently fallen into disrepute. In this paper, we want to revitalise it by providing a new argument for it and by disarming an important objection against it. A shared assumption of our competitors (intentionalists about moods) is that moods are ‘diffuse’. First, we will provide reasons for thinking that existing intentionalist views do not in fact capture this distinctive feature of moods that distinguishes them from emotions. Second, we offer a dispositionalist alternative that (...) we think does better. Finally, we disarm the objection that is responsible for dispositionalism’s bad press. (shrink)

The social sciences must be biological ones, owing simply to the fact that they focus on the causes and effects of the behavior of members of a biological species, Homo sapiens. Our improved understanding of biology as a science and of the biological realm should enable us therefore to solve several of the outstanding problems of the philosophy of social science. The solution to these problems leaves most of the social and behavioral sciences pretty much as it finds them, though (...) it does provide improved understanding of their scope, limits, and methods. Key Words: biology • natural selection • Darwinism • models • narratives • history. (shrink)

Outside the philosophy classroom, global skeptics – skeptics about all (purported) knowledge of the external world – are rare. But there are people who describe themselves as “skeptics” about various more specific domains, including self-professed “skeptics” about the reality of anthropogenic climate change. There is little to no philosophical literature that juxtaposes the climate change skeptic with the external world skeptic. While many “traditional” epistemologists assume that the external world skeptic poses a serious philosophical challenge in a way that the (...) climate change skeptic doesn’t, many “applied” or “social” epistemologists assume that there isn’t much to be learned from debates about the external world skeptic, finding her challenge to be distant from both common sense and real-world concerns. I try to show that both of these views are mistaken. The external world skeptic raises deep questions that are important for our everyday deliberation about what to believe, and there are significant structural parallels between the arguments for external world skepticism and those for at least a form of climate change skepticism that is idealized – but not too idealized! – from the views of flesh-and-blood climate change skeptics. As such, we have strong reasons to think in parallel about how to reply to both skeptics’ challenges. I thus finish by (briefly) considering how different widespread responses to the external world skeptic might or might not generalize happily to the climate change skeptic’s challenge. (shrink)

ABSTRACTJohn Tomasi's Free Market Fairness claims to provide a principled defense of classical-liberal institutions. Respect for the development of our moral powers or “self-authorship,” according to Tomasi, requires that we make certain economic liberties basic, including freedom of contract and the right to accumulate property. Yet Tomasi's principles and his institutions are at odds. Tomasi has provided ethical grounds for defending not classical-liberal but radical-democratic, even socialist, economic freedoms. This is most vivid in Tomasi's account of the “liberties of working.” (...) He argues that it is not just the choice of work but control of the workplace experience that is a vital part of our self-authorship. If this is true, Tomasi has not given a defense of a robust right to “freedom of contract,” but rather of those rights of control over work and property that leftists have long argued for. (shrink)

The paper argues that the evident features of all human affairs of interest to the social scientist demand Darwinian explanations. It must however be recognized that the range of regularities, models, theories that a successful Darwinian research program will inspire must be heterogeneous, operate at very different scales, identify a diversity of distinct and often unrepeated processes operating through multifarious instances of blind variation and environmental selection. There will be no canonical statement of a Darwinian theory of cultural and/or social (...) affairs. (shrink)

Este texto pretende apresentar reflexões acerca do pensamento em constelação proposto por Adorno para problematizar as práticas formativas colocadas em movimento nos contextos educativos. Para tanto, nos utilizamos da pesquisa bibliográfica para pensar criticamente sobre a formação dos sujeitos nos contextos educativos. Inspirados no pensamento adorniano nos reportamos ao conceito de constelação e, posteriormente, às categorias de emancipação e autorreflexão. As problematizações construídas nesse trabalho podem contribuir para o desvelamento da multiplicidade de questões que envolvem a complexidade do campo educativo (...) e dos sujeitos que ali se constituem. Indicam a necessidade de compreender que um conceito se entrelaça com outros conceitos, que ultrapassa a linearidade e a busca de um ponto de chegada. Nessa direção, é imprescindível redimensionar os processos de formação docente, ampliando as perspectivas de formação e promovendo experiências de autorreflexão da própria razão.

My paper has two aims: to underscore the importance of differently time-indexed ‘ought implies can’ principles; and to apply this to the culpable inability problem. Sometimes we make ourselves unable to do what we ought, but in those cases, we may still fail to do what we ought. This is taken to be a serious problem for synchronic ‘ought implies can’ principles, with a simultaneous ‘ought’ and ‘can’. Some take it to support diachronic ‘ought implies can’, with a potentially temporally (...) distinct ‘ought’ and ‘can’. I will argue that this problem is not avoided by diachronic ‘ought implies can’. (shrink)

Skill building is a widely recognized teaching goal in philosophy. Some well-researched skill building techniques include scaffolded assignment design, low-stakes assignments, and peer-review. Many papers have highlighted the efficacy of these techniques by demonstrating novel course and assignment design; for example, the use of blogging in philosophy courses has been shown to have positive results on student writing. While the efficacy of skill building centered course design on student learning seems uncontroversial, two major problems are typically raised: the time investment (...) for such course design is significant and implementing these techniques in large classes is not possible. The central aim of this paper is to combat this second claim. I present a course designed around skill building that has been successfully implemented in classes of from 120 to 450 students. I show some techniques that make this implementation possible and not unwieldy, and I argue that students both improved their philosophical skills and enjoyed the course design. (shrink)

: In this commentary on Sinhababu’s Humean Nature I will explore three lines of inquiry. The first asks about the explanatory power of the Desire-Belief Theory of Reasoning, by way of wondering about how desires and beliefs combine with one another. The second question continues along these lines, asking about the further conditions Sinhababu places on reasoning and whether a theory of reasoning can be normatively neutral. The third points out the need for more clarity in his account of intention (...) by contrasting it with practical reasoning. Keywords: Desire; Belief; Humean Psychology; Intention; Practical Reasoning Meccanica e psicologia del ragionamento pratico Riassunto: In questo commento su Humean Nature di Neil Sinhababu intendo esplorare tre linee di indagine.

Comment on Beeghly, Erin. 2021. “Stereotyping as Discrimination: Why Thoughts Can Be Discriminatory.” Social Epistemology 35 (6): 547–63. -/- Beeghly’s “Stereotyping as Discrimination” is—characteristically—clear, thorough, and persuasive, rich with incisive arguments and thought-provoking case studies. In defending the view that stereotyping often constitutes discrimination, she makes a powerful case that, “Living ethically means cultivating a certain kind of ‘inner’ life and avoiding pernicious habits of thought, no matter how culturally pervasive” (Beeghly 2021b, 13). Support for such claims is traced back (...) not just to Aristotle and the Ten Commandments (Beeghly 2021b, 10), but also to critical social traditions. “As feminists and theorists of race have long noted, the most intimate aspects of our selves, including our ways of thinking, agency, and modes of embodiment, are among the mechanisms of group oppression” (Beeghly 2021b, 13). I offer, first, a tiny friendly amendment to one brief passage, followed by invitations to explore some of the further potential implications of Beeghly’s central theses. (shrink)

MEDIA and humanitarian organizations inundate us with headlines and press releases decrying the “Global Refugee Crisis”, the “Syrian Refugee Crisis”, the “Mediterranean Migration Crisis”, the “2014 American Immigrant Crisis” and much more. Careers in academic and policy circles are built on analyzing and proposing solutions to migration crises. The representation of migration as a crisis is a default response to the challenges of human mobility. This default response is often misguided and harmful. This claim may seem odd or even perverse. (...) Why should we represent the forced displacement of millions of women, men, and children around the world as anything other than a crisis? Nonetheless, crisis is an evaluative term, representing an event as dangerous, difficult, and exceptional and often justifying drastic measures. In what follows, I identify four ways in which the representation of migration as a crisis is an abuse, mischaracterizing the nature of migration and harming migrants. I end with a series of remarks about when migrant crisis may be an appropriate label. (shrink)

The study of economics has been a going concern among philosophers for the better part of twenty years without very many people even noticing that economics has a metaphysics. Indeed, among economists the term ‘metaphysical’ is probably an epithet of opprobrium, employed to suggest that a claim is untestable or otherwise without cognitive significance. Philosophers of economics will admit to the existence of an epistemology of economics—the study of the nature, extent and justification of economic knowledge. But even this is (...) controversial among some economists. The notion that economics might have a metaphysics as well as an epistemology will be scoffed at by those economists doubtful about the enterprise of the philosophy of economics altogether. Nevertheless, philosophers of economics should have no trouble identifying a metaphysics in some of the theoretical commitments of economics. (shrink)

Martin Buber is considered one of the twentieth century’s greatest thinkers, contributing to the fields of philosophy, theology and education. After Buber’s death the appreciation of his considerable legacy became rather muted, but was never completely forgotten. Recently, interest in Buber’s thought has increased and a number of journal articles and books dealing with both general and specific aspects of his philosophy have appeared. However, the number of commentaries on the importance of his socio-political thought are still small in number, (...) and it is arguable that only Mendes-Flohr and Avnon have provided significant discussions on this aspect of Buber’s philosophy. This article adds to the debate in this area by referring to Buber’s concept of the ‘living-centre’, and assesses the Mendes-Florian and Avnonian [my terminology] interpretations of this fundamental idea so as to establish which provides a more sustainable reading of Buber’s ideas.

The authors show that in certain isolated tissues the mitotic processes continue during at least one hour. They are very strongly stimulated by heat and also by mitogenetic radiation. In the case of the cancer cells new mitoses are promoted in considerable number. A detailed analysis of both energy factors leads to the conclusion that they effect a disturbance of the unstable constellations of the elementary particles in the cell-body. Thus a certain degree of disorganisation of its plasma seems to (...) stimulate cell-division. This statement is, in the opinion of the authors a proof that cell-division is controlled by a ”field”, the trajectories of the elementary particles of the cell-body being a function of their coordinates relative to the cell-axes.Les auteurs démontrent que dans certains tissus survivants les mitoses continuent leur processus d'évolution durant au moins une heure. Par l'application de chaleur aussi bien que par l'irradiation mitogénétique on peut accélérer beaucoup le rhythme des mitoses en cours d'évolution et provoquer l'apparition d'un nombre considérable de nouvelles mitoses. L'analyse de l'action de ces deux facteurs d'énergie aboutit à la conclusion qu'il ne peut s'agir que d'un dérangement des constellations instables des éléments du corps cellulaire. On peut en déduire qu'un certain degré de désorganisation du plasme est favorable aux divisions cellulaires. En poursuivant et en développant cette conception, les auteurs arrivent à la conception du „champ cellulaire de division”, définissant les trajectoires des particules élémentaires comme fonction de ses coordonnés relativement aux axes des cellules.

This paper argues that the consensus physicalist antireductionism in the philosophy of biology cannot accommodate the research strategy or indeed the recent findings of molecular developmental biology. After describing Wolperts programmatic claims on its behalf, and recent work by Gehring and others to identify the molecular determinants of development, the paper attempts to identify the relationship between evolutionary and developmental biology by reconciling two apparently conflicting accounts of bio-function – Wrights and Nagels (as elaborated by Cummins). Finally, the paper seeks (...) a way of defending the two central theses of physicalist antireductionism in the light of the research program of molecular developmental biology, by sharply reducing their metaphysical force.

Epicurus posited that the best life involves the greatest pleasures. He also argued that it involves attaining tranquillity. Many commentators have expressed scepticism that these two claims are compatible. For, they argue, Epicurus’ tranquil life is so austere that it is hard to see how it could be maximally pleasurable. Here, I offer an Epicurean account of the pleasures of tranquillity. I also consider different ways of valuing lives from a hedonistic point of view. Benthamite hedonists value lives by the (...) sum of pleasures minus the sum of pains, weighted by intensity and duration. Meanwhile, Binmore proposes that Epicurus valued lives by their worst episode. In contrast, I offer an Epicurean argument for why the best life is one in which a person attains tranquillity and tastes its pleasures until death. (shrink)
