An increasing number of scholars argue that moral judgements are adaptations, i.e., that they have been shaped by natural selection. Is this hypothesis true? In this paper I shall not attempt to answer this important question. Rather, I pursue the more modest aim of pointing out three difficulties that anybody who sets out to determine the adaptedness of moral judgments should be aware of (though some so far have not been aware of). First, the hypothesis that moral judgements are adaptations (...) has been advocated in various different specificities and scopes, and on various different levels. Second, the three kinds of evidence that have most often been appealed to by discussants of this hypothesis require additional arguments. And third, there is significant reasonable disagreement about what moral judgements essentially are. (shrink)

Using concepts of evolutionary game theory, this paper presents a critique of ethical intuitionism, or non-naturalism, in its cognitivist and objectivist interpretation. While epistemological considerations suggest that human rational learning through experience provides no basis for objective moral knowledge, it is argued below that modern evolutionary theory explains why this is so, i.e., why biological organisms do not evolve so as to experience objective preferences and obligations. The difference between the modes of the cognition of objective and of valuative environmental (...) attributes is explained with reference to different modes of natural selection acting on the cognitive apparatus of the organism. The negative implications are pointed out which the observable diversity of intraspecific behavioural adaptations and of cultural values has for the cognitivist, objectivist foundation of ethics. Eventually a non-cognitivist alternative to ethical intuitionism is outlined in terms of empirical authority relations, with the ritualisation of dominance-submission patterns as the evolutionary origin of human charismatic authority.

In recent years, a proliferation of books about empathy, cooperation and pro-social behaviours (Brooks, 2011a) has significantly influenced the discourse of the life-sciences and reversed consolidated views of nature as a place only for competition and aggression. In this article I describe the recent contribution of three disciplines – moral psychology (Jonathan Haidt), primatology (Frans de Waal) and the neuroscience of morality – to the present transformation of biology and evolution into direct sources of moral phenomena, a process here named (...) the ‘moralization of biology’. I conclude by addressing the ambivalent status of this constellation of authors, for whom today ‘morality comes naturally’: I explore both the attractiveness of their message, and the problematic epistemological assumptions of their research programmes in the light of new discoveries in developmental and molecular biology.

In this paper I argue that any adequate evolutionary ethical theory needs to account for moral belief as well as for dispositions to behave altruistically. It also needs to be clear whether it is offering us an account of the motivating reasons behind human behaviour or whether it is giving justifying reasons for a particular set of behaviours or, if both, to distinguish them clearly. I also argue that, unless there are some objective moral truths, the evolutionary ethicist cannot offer (...) justifying reasons for a set of behaviours. I use these points to refute Waller's claims that the illusion of objectivity plays a dispensable role in Ruse's theory, that my critique of Ruse's Darwinian metaethics is built on a false dilemma, that there is nothing to be distressed about if morality is not objective, and that ethical beliefs are subject to a kind of causal explanation that undermines their objectivity in a way that scientific beliefs are not.

The paper distinguishes three strategies by means of which empirical discoveries about the nature of morality can be used to undermine moral judgements. On the first strategy, moral judgements are shown to be unjustified in virtue of being shown to rest on ignorance or false belief. On the second strategy, moral judgements are shown to be false by being shown to entail claims inconsistent with the relevant empirical discoveries. On the third strategy, moral judgements are shown to be false in (...) virtue of being shown to be unjustified; truth having been defined epistemologically in terms of justification. By interpreting three recent error theoretical arguments in light of these strategies, the paper evaluates the epistemological and metaphysical relevance of empirical discoveries about morality as a naturally evolved phenomenon.

In this article, I explore the method of genealogy in moral philosophy, with a focus on evaluating the credibility of moral progress judgments. Despite genealogy becoming a new trend in this field, I critique three types of defective grand narrative genealogies represented by the works of Peter Railton, Michael Huemer, and Nicholas Smyth. I argue that their genealogies fail to be adequate for evaluating moral progress judgments’ credibility. Railton’s genealogy lacks specificity regarding the relatum of the causal story he presents, (...) Huemer’s fails to withstand the scrutiny of historical evidence, and Smyth’s gives no clear verdict on the credibility of the moral progress judgments it explains. These failures, I argue, stem from grand narratives’ neglect of the particularities in each case of moral belief emergence. The disregard for details renders grand narratives generally inadequate for credibility evaluation. Instead, I propose a case study approach that takes into account four types of particulars in each case. I argue that this approach is more methodologically adequate in evaluating the credibility of moral progress judgments since these case-specific details are essential in determining the credibility of a moral belief.

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)

This paper sketches an alternative answer to James Jones's recent attempt to explore the implications of cognitive social learning theories of personality for issues in epistemology, philosophy of science, and religious studies. Since the 1960s, two cognitive revolutions have taken place in scientific psychology: the first made cognition central to theories of perception, memory, problem solving, and so on; the second made cognition central to theories of learning and behavior, among others. Cognitive social learning theories find their place in the (...) latter revolution. Because of an ongoing naturalistic revolution in philosophy, these cognitive revolutions in psychology are having a profound effect on both descriptive and normative issues in epistemology and philosophy of science. From the naturalistic perspective, philosophy cannot adequately pursue its goals without the contributions of the empirical sciences, including psychology. The author concludes that the cognitive revolutions in psychology and the naturalistic revolution in philosophy have similar descriptive and normative import for the study of religion. (shrink)

We propose an objective and justifiable ethics that is contingent on the truth of evolutionary theory. We do not argue for the truth of this position, which depends on the empirical question of whether moral functions form a natural class, but for its cogency and possibility. The position we propose combines the advantages of Kantian objectivity with the explanatory and motivational advantages of moral naturalism. It avoids problems with the epistemological inaccessibility of transcendent values, while avoiding the relativism or subjectivism (...) often associated with moral naturalism. Our position emerges out of criticisms of the contemporary sociobiological views of morality found in the writings of Richard Alexander, Michael Ruse, and Robert Richards. (shrink)

Michael Ruse, in Taking Darwin Seriously seeks to establish that taking Darwin seriously requires us to treat morality as subjective and naturalistic. I argue that, if morality is not objective, then we have no good reason for being moral if we can avoid detection and punishment. As a consequence, we will only continue to behave morally as long as we remain ignorant of Ruse''s theory, that is, as long as the cat is not let out of the bag. Ruse offers (...) a number of arguments to show that his theory can overcome such problems. I argue that they all fail. Ruse also argues that he can offer a naturalistic account of ethics which steps around the naturalistic fallacy and avoids the confusion of reasons with causes. His principal argument for this view is an analogy between spiritualism and morality. I argue that this analogy fails. (shrink)

Out of a concern to respect the naturalistic fallacy, Ruse (1986) argues for the possibility of causal, but not justificatory, explanations of morality in terms of evolutionary processes. In a discussion of Ruse's work, Rottschaefer and Martinsen (1990) claim that he erroneously limits the explanatory scope of evolutionary concepts, because he fails to see that one can have objective moral properties without committing either of two forms of the naturalistic fallacy, if one holds that moral properties supervene on non-moral properties. (...) In this short paper I argue that Rottschaefer and Martinsen's solution fails. If one takes moral properties to supervene on non-moral properties, then either one ends up committing one of the two forms of the naturalistic fallacy or else one is left postulating unbelievable brute metaphysical facts.

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)

In this article (1) I extract from Brentano’s works (three) formal arguments against “genealogical explanations” of ethical claims. Such explanation can also be designated as “naturalism” (not his appellation); (2) I counter these arguments, by showing how genealogical explanations of even apodictic moral claims are logically possible (albeit only if certain unlikely, stringent conditions are met); (3) I show how Nietzsche’s ethics meets these stringent conditions, but evolutionary ethics does not. My more general thesis is that naturalism and intuitionism in (...) ethics need not be mutually incompatible. (shrink)

In a recent paper in this journal (Rottschaefer and Martinsen 1990) we have proposed a view of Darwinian evolutionary metaethics that we believe improves upon Michael Ruse's (e.g., Ruse 1986) proposals by claiming that there are evolutionary based objective moral values and that a Darwinian naturalistic account of the moral good in terms of human fitness can be given that avoids the naturalistic fallacy in both its definitional and derivational forms while providing genuine, even if limited, justifications for substantive ethical (...) claims. Jonathan Barrett (this issue) has objected to our proposal contending that we cannot hold for the reality of supervenient moral properties without either falling foul of the naturalistic fallacy or suffering the consequences of postulating inexplicable moral properties. In reply, we show that Barrett's explicit arguments that we commit either the definitional or derivational form of the naturalistic fallacy fail and that his naturalistic intuitions that supervenience explanations of moral properties by nonmoral properties force us into what we call the explanatory form of the naturalistic fallacy also fail. Positively, his objections help us to clarify the nature of the naturalistic fallacy within an evolutionary based naturalistic ethics and to point out the proper role of both supervenience explanations and moral explanations in such an ethics.

Examining James M. Gustafson's views on the relationships between the sciences, theology, and ethics from a scientifically based naturalistic philosophical perspective, I concur with his rejection of separatist and antagonistic interactionist positions and his adherence to a mutually supportive interactionist position with both descriptive and normative features. I next explore three aspects of this interactionism: religious empiricism, the connections between facts and values, and the centering of objective values in the divine. Here I find much accord between Gustafson's theocentrism and (...) a scientifically based naturalistic philosophical account of the relationships between the sciences, theology, and ethics. (shrink)

Suppose that the human tendency to think of certain actions andomissions as morally required – a notion that surely lies at the heart of moral discourse – is a trait that has been naturallyselected for. Many have thought that from this premise we canjustify or vindicate moral concepts. I argue that this is mistaken, and defend Michael Ruse's view that the moreplausible implication is an error theory – the idea thatmorality is an illusion foisted upon us by evolution. Thenaturalistic fallacy (...) is a red herring in this debate,since there is really nothing that counts as a ‘fallacy’ at all. If morality is an illusion, it appears to followthat we should, upon discovering this, abolish moraldiscourse on pain of irrationality. I argue that thisconclusion is too hasty, and that we may be able usefullyto employ a moral discourse, warts and all, withoutbelieving in it. (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.

Charles J. Lumsden and E.O. Wilson, in their writings together and individually, have proposed that human behaviors, whether moral or nonmoral, are governed by innate constraints (which they have termed epigenetic rules). I propose that if a genetic component of moral behavior is to be discovered, some sorting out of specifically moral from nonmoral innate constraints will be necessary. That some specifically moral innate constraits exist is evidenced by virtuous behaviors exhibited in nonhuman mammals, whose behavior is usually granted to (...) be importantly governed by genetic factors. Propensities for such virtuous behaviors may have been passed to humans as highly conserved mammalian genes and continue to influence us. I propose that these constitute at least a rudimentary morality and may account in part for the moral intuitions. But other innate constraints which are nonmoral in nature interact with the specifically moral innate constraints and with culture to yield human moral decisions and actions. Any model which aims to identify the genetic component of moral behaviors or behaviors with moral import must provide not only a delineation of cultural causes but must also distinguish between those genetic causes which may have their origin in innate moral constraints from others which are fundamentally nonmoral because the critical faculty necessary to higher level human morality itself arises in part from innate constraints of a nonmoral type; i.e., the processes of inductive reasoning common to both ethics and science. Finally, humans who could bring the nonmoral evaluative capacities to bear upon whatever moral intuitions might be genetically conserved in mammalian heritage would have an advantage over similar beings who could not.

This paper makes an attempt at the conceptual foundation of descriptive ethical theories in terms of evolutionary anthropology. It suggests, first, that what human social actors tend to accept to be morally valid and legitimate ultimately rests upon empirical authority relations and, second, that this acceptance follows an evolved pattern of hierarchical behaviour control in the social animal species. The analysis starts with a brief review of Thomas Hobbes'' moral philosophy, with special emphasis on Hobbes'' authoritarian view of moral validity (...) and of the common political origins and ultimate basis of legitimacy of moral and legal systems. Hobbes'' philosophical conceptions are then put into the context of Max Weber''s influential empirical theory of legitimacy, especially charismatic revelation and authority as the ultimate source of all moral, legal and religious obligations. Weber''s concept of charismatic authority is given a biobehavioural interpretation in terms of ritualised status signals indicating an individual''s superior physical and emotional dispositions to control the social actions of others. Various conclusions are drawn concerning the concept of moral validity and its possible evolutionary interpretations. (shrink)
