A simple numerical procedure is presented for the problem of estimating the parameters of models for the distribution of eggs oviposited in a host. The modelling is extended to incorporate both host density and time dependence to produce a remarkably parsimonious structure with only seven parameters to describe a data set of over 3,000 observations. This is further refined using a mixed model to accommodate several large outliers. Both models show that the level of superparasitism declines with increasing host density, (...) and the rate declines over time. It is proposed that the differing behaviours represented by the mixed model may reflect a balance between behavioural strategies of different selective benefit. (shrink)

Geoffrey Rose’s prevention paradox points to a tension between two prima facie plausible moral principles: that we should save the greater number and that weshould save the most at risk. This paper argues that a novel moral theory, ex-ante contractualism, captures our intuitions in many prevention paradox cases, regardless of our interpretation of probability claims. However, it goes on to show that it might be impossible to square ex-ante contractualism with all of our moral intuitions. It concludes that even if (...) ex-ante contractualism cannot furnish an entire ethics of risk, it does identify important considerations for any such theory. (shrink)

In this book, John Dryzek criticizes the dominance of instrumental rationality and objectivism in political institutions and public policy and in the practice of political science. He argues that the reliance on these kinds of politics and to technocracies of expert cultures that are not only repressive, but surprisingly ill-equipped for dealing with complex social problems. Drawing on critical theory, he outlines an alternative program for the organization of political institutions advocating a form of communicatively rational democracy, which he (...) terms discursive democracy, that stresses the importance of active citizenship and public discourse. He draws out the limitations of instrumental rationality and investigates how policy analysis and political science may be reformed to help constitute and comprehend democracy. Discursive Democracy examines how the political process can be made more vital and meaningful. At the same time it shows how such an invigorated process will serve as a more effective agent for social problem solving. (shrink)

The theory of deliberative democracy is here furthered in terms of three images that locate its essence in respectively a single forum, a deliberative system, and an encompassing polity featuring particular integrative norms. The first two are ubiquitous, though contested, the third is stated here. Deliberative theorists need to contemplate how practices that make sense in each image connect to the other two. Forums only make sense when linked in a system that can synthesize very different deliberative virtues. Any system’s (...) democratic qualities can only be evaluated in terms of the polity. While judgment in terms of the conditions of normative integration in the polity is therefore primary, particular forums can promote deliberative authenticity in a system, and systems enable inclusive application of deliberative ideals. Deployed in this way, the three images help solve internal disputes and respond to critics. (shrink)

Developments in the democratic theory of representation and deliberation enable renewed consideration of the ancient controversy over the proper place of rhetoric in politics. Rhetoric facilitates the making and hearing of representation claims spanning subjects and audiences divided in their commitments and dispositions. Deliberative democracy requires a deliberative system with multiple components whose linkage often needs rhetoric. Appreciation of these aspects of democracy exposes the limitations of categorical tests for the admissibility of particular sorts of rhetoric. Prioritization of bridging over (...) bonding rhetoric is a step in the right direction, while sometimes producing misleading results. A better systemic test asks whether or not rhetoric promotes an effective deliberative system linking competent and reflective actors. (shrink)

In Amartya Sen’s The Idea of Justice, democracy is necessary for the reconciliation of plural justice claims. Sen’s treatment of democracy is however incomplete and inadequate: democracy is under-specified, there are unrecognized difficulties in any context featuring deep moral disagreement or deep division and a conceptualization of public reason in the singular erodes his pluralism. These faults undermine Sen’s account of justice. Developments in the theory of deliberative democracy can be deployed to remedy these deficiencies. This deployment points to a (...) deliberative system encompassing those affected by collective decisions, with places for non-partisan forums and discursive representatives, conditionally open to multiple forms of communication, and geared to the production of workable agreements under normative and discursive meta-consensus. Democracy does not guarantee justice, but in a plural world it is essential to the pursuit of justice. (shrink)

Contending discourses underlie many of the worlds most intractable conflicts, producing misery and violence. This is especially true in the post-9/11 world. However, contending discourses can also open the way to greater dialogue in global civil society and across states and international organizations. This possibility holds even for the most murderous sorts of conflicts in deeply divided societies. In this timely and original book, John Dryzek examines major contemporary conflicts in terms of clashing discourses. Topics covered include the alleged (...) clash of civilizations; societies divided by ethnicity, nationality, or religion; economic globalization versus resistance; plus an in-depth discussion of the 'war on terror'. Dryzek concludes by highlighting the limitations of current neoconservative and cosmopolitan approaches, arguing that only deliberative global politics offers unprecedented new possibilities for democratic engagement in the international system. This book will be of interest to students and scholars of international relations, politics, philosophy, and sociology. (shrink)

Deliberative democracy puts communication and talk at the centre of democracy. Foundations and Frontiers of Deliberative Governance takes a fresh look at the foundations of the field, and develops new applications in areas ranging from citizen participation to the democratization of authoritarian states to the global system.

Democratic theorists often place deliberative innovations such as citizen's panels, consensus conferences, planning cells, and deliberative polls at the center of their hopes for deliberative democratization. In light of experience to date, the authors chart the ways in which such mini-publics may have an impact in the “macro” world of politics. Impact may come in the form of actually making policy, being taken up in the policy process, informing public debates, market-testing of proposals, legitimation of public policies, building confidence and (...) constituencies for policies, popular oversight, and resisting co-option. Exposing problems and failures is all too easy. The authors highlight cases of success on each of these dimensions. (shrink)

I sin udmærkede kommentar til vores artikel «En etisk diskussion af screening for kræftsygdomme» beskriver Geir Hoff den udtalte mangel på evidens vedrørende nytteværdien af screeningsprogrammer for kræftsygdomme baseret på randomiserede studier. Ydermere fremhæver Geir Hoff misforholdet mellem den manglende evidens ved screening og de strenge krav, der er til evidensen i den farmaceutiske industri. Dette er en velkommen kritik, pga. en udtalt ukritisk og uvidenskabelig tilgang til anvendelse af screening for denne eller hin sygdom eller risikofaktor.

The idea that technologies can change moral beliefs and practices is an old one. But how, exactly, does this happen? This paper builds on an emerging field of inquiry by developing a synoptic taxonomy of the mechanisms of techno-moral change. It argues that technology affects moral beliefs and practices in three main domains: decisional (how we make morally loaded decisions), relational (how we relate to others) and perceptual (how we perceive situations). It argues that across these three domains there are (...) six primary mechanisms of techno-moral change: (i) adding options; (ii) changing decision-making costs; (iii) enabling new relationships; (iv) changing the burdens and expectations within relationships; (v) changing the balance of power in relationships; and (vi) changing perception (information, mental models and metaphors). The paper also discusses the layered, interactive and second-order effects of these mechanisms. (shrink)

Exclusively instrumental notions of rationality not only reinforce attitudes conducive to the destruction of the natural world, but also undermine attempts to construct environmental ethics that involve more harmonious relationships between humans and nature. Deep ecologists and other ecological critics of instrumental rationality generally prefer some kind of spiritual orientation to nature. In this paper I argue against both instrumental rationalists and ecological spiritualists in favor of a communicative rationality which encompasses the natural world. I draw upon both critical theory (...) and recent scientific intimations of agency in nature. (shrink)

We develop an account of societal democratization that synthesizes cultural sociology and deliberative democracy. Cultural sociologists emphasize the symbolic inclusion of marginalized groups into the civil sphere. Deliberative democrats stress growth in the deliberative capacity of society. We argue that democratization entails the co-evolution of culture and reason. The basis of co-evolution is the performative construction of an inclusive demos, which requires a deliberative background but is also a source of the moral emotions that motivate deliberation. Since moral emotions can (...) also sweep people up and make them do reckless things, they must in turn be redeemable in inclusive deliberation. This synthesis sharpens a normative position for the evaluation of episodes of inclusion, extends current accounts of the place of emotion in cultural sociology and deliberative democracy, and provides a frame for comparative analyses of democratization. We illustrate with an examination of the exclusion and inclusion of Indigenous Australians. (shrink)

The Nature of Classification discusses an old and generally ignored issue in the philosophy of science: natural classification. It argues for classification to be a sometimes theory-free activity in science, and discusses the existence of scientific domains, theory-dependence of observation, the inferential relations of classification and theory, and the nature of the classificatory activity in general. It focuses on biological classification, but extends the discussion to physics, psychiatry, meteorology and other special sciences.

Arguments against essentialism in biology rely strongly on a claim that modern biology abandoned Aristotle's notion of a species as a class of necessary and sufficient properties. However, neither his theory of essentialism, nor his logical definition of species and genus (eidos and genos) play much of a role in biological research and taxonomy, including his own. The objections to natural kinds thinking by early twentieth century biologists wrestling with the new genetics overlooked the fact that species have typical developmental (...) cycles and most have a large shared genetic component. These are the "what-it-is-to-be" members of that species. An intrinsic biological essentialism does not commit us to Aristotelian notions, nor even modern notions, of essence. There is a long-standing definition of "species" and its precursor notions that goes back to the Greeks, and which Darwin and pretty well all biologists since him share, that I call the Generative Conception of Species. It relies on there being a shared generative power that makes progeny resemble parents. The "what-it-is-to-be" a member of that species is that developmental type, mistakes in development notwithstanding. Moreover, such "essences" have always been understood to include deviations from the type. Finally, I shall examine some implications of the collapse of the narrative about essences in biology.

Ideas about the presence, absence, and growth of democracy in global politics take different forms. After surveying the basic justifications for global democracy, three frames for making sense of the significance of particular developments and proposals are canvassed. “Soup” involves the proliferation of democratic practices, though the consequences of this proliferation for the overall shape of international politics remain open. “Society” stresses the democratization of processes that affect constitutive norms and discourses. “System” identifies differentiated yet ordered parts, geared to the (...) production of collective outcomes. The soup framing is undemanding yet limited. System provides a way to pinpoint democratic deficiencies and possibilities, but its requirements can be highly demanding, and it leaves open the question of normative integration. Understanding global democratization requires both society and system framings. (shrink)

Essentialism in philosophy is the position that things, especially kinds of things, have essences, or sets of properties, that all members of the kind must have, and the combination of which only members of the kind do, in fact, have. It is usually thought to derive from classical Greek philosophy and in particular from Aristotle’s notion of “what it is to be” something. In biology, it has been claimed that pre-evolutionary views of living kinds, or as they are sometimes called, (...) “natu-ral kinds”, are essentialist. This static view of living things presumes that no tran-sition is possible in time or form between kinds, and that variation is regarded as accidental or inessential noise rather than important information about taxa. In contrast it is held that Darwinian, and post-Darwinian, biology relies upon varia-tion as important and inevitable properties of taxa, and that taxa are not, therefore, kinds but historical individuals. Recent attempts have been made to undercut this account, and to reinstitute essentialism in biological kind terms. Others argue that essentialism has not ever been a historical reality in biology and its predecessors. In this chapter, I shall outline the many meanings of the notion of essentialism in psychology and social science as well as science, and discuss pro- and anti-essentialist views, and some recent historical revisionism. It turns out that nobody was essentialist to speak of in the sense that is antievolutionary in biology, and that much confusion rests on treating the one word, “essence” as meaning a single notion when in fact there are many. I shall also discuss the philosophical implica-tions of essentialism, and what that means one way or the other for evolutionary biology. Teaching about evolution relies upon narratives of change in the ways the living world is conceived by biologists. This is a core narrative issue. (shrink)

In this paper, I set out two ethical complications for Rid and Wendler’s proposal that a “Patient Preference Predictor” (PPP) should be used to aid decision making about incapacitated patients’ care. Both of these worries concern how a PPP might categorize patients. In the first section of the paper, I set out some general considerations about the “ethics of apt categorization” within stratified medicine and show how these challenge certain PPPs. In the second section, I argue for a more specific—but (...) more contentious—claim that proper respect for the autonomy of incapacitated patients might require us to act on reasons which they could endorse and show how this claim places important limits on the categories employed by an ethically acceptable PPP. The conclusion shows how these concerns about apt categorization relate to more familiar worries about Rid and Wendler’s proposals. (shrink)

This paper relates to Lyotard's philosophy of a différend. The paper has a dual purpose. The first is to explain what is meant by a différend and also a petit différend. The intention here is to preserve both the intrinsic validity and ethico-political value of the concept in cases where its legitimacy might easily be denied. This feeds into the second and main purpose of the paper, which is to testify to a petit différend in quality of care, so that (...) care may be taken in how the term ‘quality of care’ is actually used. It is here that the implications of a petit différend in quality of care are opened up from the perspective of cared-for and professional carers, respectively. It will be shown that the idea of quality of care is open to multiple interpretations, and therefore to disputes that judgement cannot resolve to the satisfaction of all parties. (shrink)

The vision of natural kinds that is most common in the modern philosophy of biology, particularly with respect to the question whether species and other taxa are natural kinds, is based on a revision of the notion by Mill in A System of Logic. However, there was another conception that Whewell had previously captured well, which taxonomists have always employed, of kinds as being types that need not have necessary and sufficient characters and properties, or essences. These competing views employ (...) different approaches to scientific methodologies: Mill’s class-kinds are not formed by induction but by deduction, while Whewell’s type-kinds are inductive. More recently, phylogenetic kinds (clades, or monophyletic-kinds) are inductively projectible, and escape Mill’s strictures. Mill’s version represents a shift in the notions of kinds from the biological to the physical sciences. (shrink)

For contemporary democratic theorists, democracy is largely a matter of deliberation. But the recent rise of deliberative democracy (in practice as well as theory) coincided with ever more prominent identity politics, sometimes in murderous form in deeply divided societies. This essay considers how deliberative democracy can process the toughest issues concerning mutually contradictory assertions of identity. After considering the alternative answers provided by agonists and consociational democrats, the author makes the case for a power-sharing state with attenuated sovereignty and a (...) more engaged deliberative politics in a public sphere that is semidetached from the state and situated transnationally.

Would democratic theory in its empirical and normative guises be in a better position without the theory of the deliberative public sphere? In this paper I explore recent theories of agonistic democracy that have answered this question in the affirmative. I question their assertionthat the theory of the public sphere should be abandoned in favor of a model of democratic politics based on political contestation. Furthermore, I explore one of the fundamental assumptionsat work in the debate about the theory of (...) the public sphere’s status, namely the assumed opposition between consensus and contestation. Questioning the rigid nature of the opposition, I go on to argue that the deliberative theory of the public sphere actually facilitates the development of the agonistic approach to democratic theory and practice. Key Words: agonistic democracy • deliberative democracy • democratic theory • Habermas • theory of the public sphere. (shrink)
