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)

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)

Ever since Darwin people have worried about the sceptical implications of evolution. If our minds are products of evolution like those of other animals, why suppose that the beliefs they produce are true, rather than merely useful? We consider this problem for beliefs in three different domains: religion, morality, and commonsense and scientific claims about matters of empirical fact. We identify replies to evolutionary scepticism that work in some domains but not in others. One reply is that evolution can be (...) expected to design systems that produce true beliefs in some domain. This reply works for commonsense beliefs and can be extended to scientific beliefs. But it does not work for moral or religious beliefs. An alternative reply which has been used defend moral beliefs is that their truth does not consist in their tracking some external state of affairs. Whether or not it is successful in the case of moral beliefs, this reply is less plausible for religious beliefs. So religious beliefs emerge as particularly vulnerable to evolutionary debunking.

Few problems in the philosophy of evolutionary biology are more widely disseminated and discussed than the charge of Darwinian evolution being a tautology. The history is long and complex, and the issues are many, and despite the problem routinely being dismissed as an introductory-level issue, based on misunderstandings of evolution, it seems that few agree on what exactly these misunderstandings consist of. In this paper, I will try to comprehensively review the history and the issues. Then, I will try to (...) present the following “solution”, or, one might say, “dissolution”, of the problem, and consider the wider implications of formal, or schematic, explanations in science: yes, the principle of natural selection is a tautology, and so what? It is a promissory note for actual, physical, explanations in particular cases, and is none the worse for that. This is not a new argument, of course, but it does point up the importance of formal schematic models in science. (shrink)

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.

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)

Genes are thought to have evolved from long-lived and multiply-interactive molecules in the early stages of the origins of life. However, at that stage there were no replicators, and the distinction between interactors and replicators did not yet apply. Nevertheless, the process of evolution that proceeded from initial autocatalytic hypercycles to full organisms was a Darwinian process of selection of favourable variants. We distinguish therefore between Neo-Darwinian evolution and the related Weismannian and Central Dogma divisions, on the one hand, and (...) the more generic category of Darwinian evolution on the other. We argue that Hull’s and Dawkins’ replicator/interactor distinction of entities is a sufficient, but not necessary, condition for Darwinian evolution to take place. We conceive the origin of genes as a separation between different types of molecules in a thermodynamic state space, and employ a notion of reproducers. (shrink)

Abstract Charles Darwin, in his discussions with Asa Gray and in his published works, doubted whether God could so arrange it that exactly the desired contingent events would occur to cause particular outcomes by natural selection. In this paper, I argue that even a limited or neo-Leibnizian deity could have chosen a world that satisfied some arbitrary set of goals or functions in its outcomes and thus answer Darwin's conundrum. In more general terms, this supports the consistency of natural selection (...) with providentialism, and makes “theistic evolutionism” a coherent position to hold. (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.

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.

This is a book about how politics, government - and much else - needs to change in response to the transition from the Holocene to the Anthropocene, the emerging epoch of human-induced instability in the Earth system and its life-support capacities.

The biological species (biospecies) concept applies only to sexually reproducing species, which means that until sexual reproduction evolved, there were no biospecies. On the universal tree of life, biospecies concepts therefore apply only to a relatively small number of clades, notably plants andanimals. I argue that it is useful to treat the various ways of being a species (species modes) as traits of clades. By extension from biospecies to the other concepts intended to capture the natural realities of what keeps (...) taxa distinct, we can treat other modes as traits also, and so come to understand that theplurality of species concepts reflects the biological realities of monophyletic groups.We should expect that specialists in different organisms will tend to favour those concepts that best represent the intrinsic mechanisms that keep taxa distinct in their clades. I will address the question whether modes ofreproduction such as asexual and sexual reproduction are natural classes, given that they are paraphyletic in most clades. (shrink)

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)

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)

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.

To naturalize religion, we must identify what religion is, and what aspects of it we are trying to explain. In this paper, religious social institutional behavior is the explanatory target, and an explanatory hypothesis based on shared primate social dominance psychology is given. The argument is that various religious features, including the high status afforded the religious, and the high status afforded to deities, are an expression of this social dominance psychology in a context for which it did not evolve: (...) high-density populations made possible by agriculture.

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)

In 1988, David Hull presented an evolutionary account of science. This was a direct analogy to evolutionary accounts of biological adaptation, and part of a generalized view of Darwinian selection accounts that he based upon the Universal Darwinism of Richard Dawkins. Criticisms of this view were made by, among others, Kim Sterelny, which led to it gaining only limited acceptance. Some of these criticisms are, I will argue, no longer valid in the light of developments in the formal modeling of (...) evolution, in particular that of Sergey Gavrilets’ work on adaptive landscapes. If we can usefully recast the Hullian view of science as being driven by selection in terms of Gavrilets’ and Kaufmann’s view of there being “giant components” of high-fitness networks through any realistic adaptive landscape, we may now find it useful to ask what the adaptive pressures on science are, and to extend the metaphor into a full analogy. This is in effect to reconcile the Fisherianism of the Dawkins–Hull approach to selection and replicators, with a Wrightean drift account of social constructionist views of science, preserving, it is to be hoped, the valuable aspects of both.

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)

It is often noted that if someone has a tertiary degree in a scientific field who promotes an anti-science-establishment, antiscience, or pseudoscience agenda, they are very often engineers, dentists, surgeons or medical practitioners. While this does not mean that all members of these professions or disciplines are antiscience, of course, the higher frequency of pseudoscience among them is indicative of what I call the “deductivist mindset” regarding science itself. Opposing this is the “inductivist mindset”, a view that has been deprecated (...) among philosophers since Popper. Roughly, the deductivist mindset tends to see problems as questions that can be resolved by deduction from known theory or principle, while the inductivist sees problems as questions to be resolved by discovery. These form cognitive poles, which nobody ever purely instantiates, but a cognitive tendency to be a deductivist may explain why some people find results that conflict with prior theoretical commitments, whether scientific or not, unacceptable. The deductivist tends to be a cognitive conservative, where the inductivist tends to be a cognitive progressive, and the conservative mindset leads to a ressentiment about modernism, and hence about certain scientific results, more often, or so I shall argue in this chapter.

It is often claimed there is information in some biological entity or process, most especially in genes. Genetic “information” refers to distinct notions, either of concrete properties of molecular bonds and catalysis, in which case it is little more than a periphrasis for correlation and causal relations between physical biological objects (molecules), or of abstract properties, in which case it is mind-dependent. When information plays a causal role, nothing is added to the account by calling it “information”. In short, if (...) genetic information is concrete, it is causality. If it is abstract, it is in the head. (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)

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)

This chapter distinguishes between two mindsets about science—the deductivist mindset and inductivist mindset—and explores the cognitive styles relating to authority and tradition in both science and pseudoscience. The deductivist tends to see problems as questions to be resolved by deduction from known theory or principle. The inductivist sees problems as questions to be resolved by discovery. Those leaning towards a deductivist mindset may find results that conflict with prior theoretical commitments unacceptable. The deductivist tends to be a cognitive conservative, and (...) the inductivist a cognitive progressive. The conservative mindset more often leads to resentment about modernism and hence about certain scientific results. (shrink)

Summarya) Bell tries to formulate more explicitly a notion of “local causality”: correlations between physical events in different space‐time regions should be explicable in terms of physical events in the overlap of the backward light cones. It is shown that ordinary relativistic quantum field theory is not locally causal in this sense, and cannot be embedded in a locally causal theory.b) Clauser, Home and Shimony criticize several steps in Bell's argument that any theory of local “beables” is incompatible with quantum (...) mechanics. It is contended that the Clauser‐Horne derivation of a Bell‐type inequality circumvents his weak steps. The Clauser‐Horne derivation must assume that there are no undetected correlations between choices of controllable variables in two space‐like separated regions. Methodological considerations support this assumption.c) In response to criticism by Shimony, Home, and Clauser, Bell tries to clarify the argument of “The theory of local beables”, and to defend as permissible the hypothesis of free variables.d) Bell's reply to an earlier criticism by Shimony, Clauser, and Home is answered. The convergence of Bell's position towards theirs is noted. (shrink)

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)

The Byzantine rite of ordination to the presbyterate culminates in the conferral of a portion of the Eucharist upon the newly-ordained by the bishop. After reviewing the historical roots of this rite, this article examines the philological and biblical background of the term. Parakatathêkê coincides with the notion of paradosis but goes beyond it in personal and eschatological senses. Three simultaneous but distinct acts of personal transmission are highlighted: the personal participation of the newly-ordained in the apostolic ministry of the (...) bishop; the handing over of Christ personally present in the Eucharist to the newly-ordained; and the corresponding personal surrender of the new priest to Christ, to whom he will render an account of his own realization of Christ's priesthood in the service of His Mystical Body, the Church.
