Evolutionary ethics has recently become popular again. Some of its representatives elaborate new attempts to derive ethics from evolutionary biology. The attempts, like previous ones, fail because they commit the naturalistic fallacy. Premises from evolutionary biology together with normative premises also do not justify ethical principles. Other representatives argue that evolutionary considerations imply that ethics cannot be justified at all. Their arguments presuppose an unacceptable form of foundationalism. In principle, evolutionary biology might explain some aspects of morality, but in practice (...) explanations are hard to come by. All this does not imply that evolutionary theory is irrelevant in normative settings. To the contrary, it may help us devise guidelines in environmental policy and health care policy. It is to be hoped that evolutionary ethicists will divert their research efforts to the elaboration of such guidelines. (shrink)

Christian ethics accentuates in manifold ways the unique character of human nature. Personalists believe that the mind is never reducible to material and physical substance. The human person is presented as the supreme principle, based on arguments referring to free-willed actions, the immateriality of both the divine spirit and the reflexive capacity, intersubjectivity and self-consciousness. But since Darwin, evolutionary biology slowly instructs us that morality roots in dispositions that are programmed by evolution into our nature. Historically, Thomas Huxley, “Darwin's bulldog,” (...) agreed with Darwin on almost everything, except for his gradualist position on moral behavior. Huxley's “saltationism” has recently been characterized by Frans de Waal as “a veneer theory of morality.” Does this mark the end of a period of presenting morality as only the fruit of socialization processes (nurture) and as having nothing in common with nature? Does it necessarily imply a corrosion of personalist views on the human being or do Christian ethics have to become familiar again with their ancient roots? (shrink)

, Philip Kitcher has argued that science ought to meet both the epistemic goals of significant truth and the nonepistemic goals of serving the interests of a democratic society. He opposes this science as servant model to both the theology of science as source of salvific truth and the theology of science as anti-Christ. In a recent critical comment, Paul A. Roth argues that Kitcher remains entangled in the theology of salvific truth, not realizing that its goal is either vacuous (...) or unattainable. Instead of theologies, Roth proposes demythologization. In the end, science attains neither truth nor value, for these goals are incomprehensible and unattainable. Consequently, science’s goals are entirely pedestrian and without special interest. Adopting Kitcher’s own scientific naturalistic epistemology, the author argues for a naturalized theology of science, using a science as mediator model, in which both nature and scientist have a role in the acquisition of significant truth. Key Words: epistemic values • Kitcher • nonepistemic values • Roth • science and values • scientific realism • scientific truth. (shrink)

In this article I elaborate a scientifically based moral realism that I call affordance moral realism, and I offer a promissory note that affordance moral realism is the best current explanation of morality. Affordance moral realism maintains that morality is constituted by the interaction of moral agents and moral affordances. The latter are the natural and social environments in which moral agents’ activities take place and contain the objects of moral agents’ activities whose actualizations are the manifestation of substantive moral (...) goods. In making this argument, I take a scientific naturalistic approach that includes both the natural and social sciences, aiming to make my account both methodologically and substantively naturalistic. On the subject side of my affordance view, I offer a scientific account of moral agency, one based on an extension of social cognitive theories of agency to the realm of morality. And I argue that affordance moral realism explains the nature of moral agency, its acquisition, maintenance, and successful performance. To explain its origin and maintenance, I make use of a general theory of selection that embraces biological, social, cultural, and intentional selection. On the object side, I offer a theory of moral affordances and their actualizations, employing the findings and theories of moral developmental psychology and moral psychology to understand their actualizations through the successful operations of moral agents. I conclude that a scientifically based naturalistic affordance moral realism promises to provide the best current account of morality. It is not only affordable; it’s a bargain. (shrink)

The project of naturalizing ethics has multiple contributions, from cognitive and moral psychology to primatology, neuroscience or evolutionary theory. One of the strategies for naturalizing ethics has been to argue that moral norms and values can be explained away if we focus on their causal history, if it is possible to offer both an ultimate and proximate causal explanation for them. In this article, I will focus on the contribution of cognitive and moral psychology as a way of offering a (...) proximate causal explanation for moral judgments. I am mostly interested in understanding to what extent these cognitive and psychological questions have some bearing in the fields of ethics and meta-ethics. Does this research programme put at stake the contention that ethics is a manifestation of human rationality? Is it true that finding the cognitive underpinnings of some of our moral judgments vindicates some meta-ethical position, namely some kind of reductionist naturalism? In the end, I will argue that even if scientific disciplines such as cognitive psychology give us a naturalized picture of the moral agent, there seem to be no reasons to think that from a naturalized perspective of the agent capable of perceiving value it must follow the naturalization of value itself.

The Darwinian theory of evolution is itself evolving and this book presents the details of the core of modern Darwinism and its latest developmental directions. The authors present current scientific work addressing theoretical problems and challenges in four sections, beginning with the concepts of evolution theory, its processes of variation, heredity, selection, adaptation and function, and its patterns of character, species, descent and life. The second part of this book scrutinizes Darwinism in the philosophy of science and its usefulness in (...) understanding ecosystems, whilst the third section deals with its application in disciplines beyond the biological sciences, including evolutionary psychology and evolutionary economics, Darwinian morality and phylolinguistics. The final section addresses anti-Darwinism, the creationist view and issues around teaching evolution in secondary schools. The reader learns how current experimental biology is opening important perspectives on the sources of variation, and thus of the very power of natural selection. This work examines numerous examples of the extension of the principle of natural selection and provides the opportunity to critically reflect on a rich theory, on the methodological rigour that presides in its extensions and exportations, and on the necessity to measure its advantages and also its limits. Scholars interested in modern Darwinism and scientific research, its concepts, research programs and controversies will find this book an excellent read, and those considering how Darwinism might evolve, how it can apply to the human sciences and other disciplines beyond its origins will find it particularly valuable. Originally produced in French (Les Mondes Darwiniens), the scope and usefulness of the book have led to the production of this English text, to reach a wider audience. This book is a milestone in the impressive penetration by Francophone scholars into the world of Darwinian science, its historiography and philosophy over the last two decades. Alex Rosenberg, R. Taylor Cole Professor of Philosophy, Duke University Until now this useful and comprehensive handbook has only been available to francophones. Thanks to this invaluable new translation, this collection of insightful and original essays can reach the global audience it deserves. Tim Lewens, University of Cambridge. (shrink)

In the paper, after clarifying terms such as ‘identity’, ‘self’ and ‘personhood’, I propose an empirical account of identity based on the notion of “whole phenotype”. This move allows one to claim the persistence of the individuals before and after their being affected by dementia. Furthermore, I show how this account permits us to address significant questions related to demented individuals’ loss of the capacity of moral decisions.

One reason for the widespread resistance to evolutionary accounts of the origins of humanity is the fear that they undermine morality: if morality is based on nothing more than evolved dispositions, it would be shown to be illusory, many people suspect. This view is shared by some philosophers who take their work on the evolutionary origins of morality to undermine moral realism. If they are right, we are faced with an unpalatable choice: to reject morality on scientific grounds, or to (...) reject our best- confirmed scientific explanation of our origins in order to save morality. Fortunately, as I show, we have no reason to accept the deflationary claims of some evolutionary ethicists: morality, as we ordinarily understand it, is fully compatible with evolution. (shrink)

U svojoj inačici filozofije biologije Neven Sesardić izvodi dalekosežne moralne i političke posljedice određenih genetičkih istraživanja. On pretpostavlja da su uočene razlike u kvocijentu inteligencije između crnih i bijelih studenata urođene i da one ne mogu biti objašnjene niti promijenjene bilo kakvim utjecajem iz okoliša. Na toj osnovi on razvija teoriju o genetski određenoj inferiornosti crne rase. Teorija tvrdi da su svi podaci o društvenim i ekonomskim nedostatcima crne rase učinak njihovog lošeg biološkog nasljeđa, a ne društvene segregacije ili rasne (...) diskriminacije. Prema tome, bilo koja politika usmjerena na smanjivanje ili eliminiranje društvenih i ekonomskih razlika između siromašnih i bogatih ljudi, kao što je politika pozitivne diskriminacije, osuđena je na propast. U ovom se članku suprotstavljam Sesardićevu filozofskom tumačenju genetike i njegovim izvodima koji se tiču politike i društva. Pokazujem da mnogi relevantni genetičari ne prihvaćaju takvo filozofsko tumačenje i njegove političke posljedice. Suprotno Sesardićevoj tvrdnji da su svi environmentalisti zaraženi ljevičarskom političkom ideologijom, pokazujem da njih njihova znanstvena istraživanja, a ne apriorna politička uvjerenja, navode na odbacivanje jednostranih hereditarističkih filozofskih tumačenja i njihove političke primjene. Posebno sam usmjeren na povijest ropstva u Americi i na aktualne izvještaje o rasnoj diskriminaciji kao na važne elemente društvenog okoliša koji ne mogu biti zanijekani u bilo kojem ozbiljnom pokušaju objašnjavanja klasnih i rasnih odnosa u suvremenoj Americi.
