It is a common complaint that antireductionist arguments are primarily negative. Here I describe an alternative nonreductionist epistemology based on considerations taken from multidisciplinary research in biology. The core of this framework consists in seeing investigation as coordinated around sets of problems (problem agendas) that have associated criteria of explanatory adequacy. These ideas are developed in a case study, the explanation of evolutionaryinnovations and novelties, which demonstrates the applicability and fruitfulness of this nonreductionist epistemological perspective. This account (...) also bears on questions of conceptual change and theory structure in philosophy of science. †To contact the author, please write to: Department of Philosophy, University of Minnesota, 831 Heller Hall, 271 19th Ave. S., Minneapolis, MN 55455; e‐mail: aclove@umn.edu.

Will a synthesis of developmental and evolutionary biology require a focus on the role of nongenetic resources in evolution? Nongenetic variation may exist but be hidden because the phenotypes are stable (developmentally canalized) under certain background conditions. In this case, those differences may come to play important roles in evolution when background conditions change. If this is so, then a focus on the way that developmental resources are made reliable, and the ways in which reliability fails, may prove to (...) be of crucial importance to linking developmental and evolutionary biology. †To contact the author, please write to: 208 Hovland Hall, Philosophy Department, Oregon State University, Corvallis, OR 97331‐3902; e‐mail: jonathan.kaplan@oregonstate.edu.

occurs first. The biological debate is conducted largely on a theoretical level. In this paper, I undertake to locate the reason for the difference in temporal ordering. The question is whether the difference depends on alternative interpretations of empirical data, on differing views about evolutionary mechanisms, or on different conceptual frameworks. It will turn out that the latter is the case and that discerning two different notions of novelty solves the apparent contradiction. Both concepts may apply to different cases in evolution. To settle (...) the dispute by judging whether any of both concepts is empty or not has to be recommitted to science. (shrink)
One foundational question in contemporarybiology is how to `rejoin evolution anddevelopment. The emerging research program(evolutionary developmental biology or`evo-devo) requires a meshing of disciplines,concepts, and explanations that have beendeveloped largely in independence over the pastcentury. In the attempt to comprehend thepresent separation between evolution anddevelopment much attention has been paid to thesplit between genetics and embryology in theearly part of the 20th century with itscodification in the exclusion of embryologyfrom the Modern Synthesis. This encourages acharacterization of evolutionary developmentalbiology as (...) the marriage of evolutionary theoryand embryology via developmental genetics. Butthere remains a largely untold story about thesignificance of morphology and comparativeanatomy (also minimized in the ModernSynthesis). Functional and evolutionarymorphology are critical for understanding thedevelopment of a concept central toevolutionary developmental biology,evolutionary innovation. Highlighting thediscipline of morphology and the concepts ofinnovation and novelty provides an alternativeway of conceptualizing the `evo and the `devoto be synthesized. (shrink)
One foundational question in contemporary biology is how to integrate evolution and development. The emerging synthesis (evolutionary developmental biology or ‘evo-devo’) requires a meshing of disciplines, concepts, and explanations (inter alia) that have been developed largely in independence over the past century. The nature of the hoped for synthesis is not wholly agreed upon due to divergent viewpoints resulting from this disciplinary independence and, consequently, the mechanics for accomplishing the task are not clearly specified. This paper utilizes historical investigation (...) for philosophical purposes in order to explore the question of synthesizing evolutionary and developmental biology. In the attempt to comprehend the present separation between evolution and development much attention has been paid to the split between genetics and embryology in the early part of the century with its codification in the exclusion of embryology from the Modern Synthesis. This encourages a characterization of "evo-devo" as the integration of developmental genetics with Neo-Darwinism. But there is a largely untold story about the significance of morphology and comparative anatomy (also minimized in the Modern Synthesis). I will attempt to reconstruct part of this story, focusing on the rebirth of functional (and evolutionary) morphology after the 1950s. Functional morphology is critical for understanding the development of a concept central to "evo-devo", evolutionary innovation. Understanding the story about morphology and innovation reveals a different conception of the foundational problem, providing alternative ways of conceptualizing the "evo" and the "devo" to be synthesized.

Attempts to explain the origin of macroevolutionary innovations have been only partially successful. Here it is proposed that the patterns of major evolutionary transitions have to be understood first, before it is possible to further analyse the forces behind the process. The hypothesis is that major evolutionaryinnovations are characterized by an increase in organismal autonomy, in the sense of emancipation from the environment. After a brief overview of the literature on this subject, increasing autonomy is (...) defined as the evolutionary shift in the individual system–environment relationship, such that the direct influences of the environment are gradually reduced and a stabilization of self-referential, intrinsic functions within the system is generated. This is described as relative autonomy because numerous interconnections with the environment and dependencies upon it are retained. Features of increasing autonomy are spatial separations, an increase in homeostatic functions and in body size, internalizations and an increase in physiological and behavioral flexibility. It is described how these features are present in different combinations in the major evolutionary transitions of metazoans and, consequently, how they should be taken into consideration when evolutionaryinnovations are studied. The hypothesis contributes to a reconsideration of the relationship between organisms and their environment. (shrink)
Carl Hausman is a former editor of The Journal of Speculative Philosophy, a revival of one of the first American philosophy journals, where Peirce published some of his early work; and Hausman has devoted a good deal of his career to Peirce scholarship. He interprets Peirce’s thought “as a fallibilistic foundationalism that affirms a unique realism according to which what is real is a dynamic, evolving extramental condition.” The theme is an interesting one partly in view of the many recent (...) criticisms of foundationalism, some drawing on pragmatist sources. It promises to re-emphasize more conservative moments of the pragmatic conception of inquiry. Similarly, Hausman’s approach highlights the historical continuities between pragmatism and realism in American philosophy. Still, if Peircean realism implies evolutionary pressure due to “extra-mental” conditions, this suggests a question. Can we also expect a corresponding realism or autonomy of human lives, thought, and cultures—themselves evolving through their interactions? A positive answer here might help avoid the de-centering excesses of contemporary anti-foundationalists, implying social and institutional space for cross-fertilizations, innovations, and the rejection of social-institutional rigidities.

Evolutionary ethics (EE) is a branch of philosophy that arouses both fascination and deep suspicion. It claims that Darwinian mechanisms and evolutionary data on animal sociality are relevant to ethical reflection. This field of study is often misunderstood and rarely fails to conjure up images of Social Darwinism as a vector for nasty ideologies and policies. However, it is worth resisting the temptation to reduce EE to Social Darwinism and developing an objective analysis of whether it is appropriate (...) to adopt an evolutionary approach in ethics. The purpose of this article is to ‘dedemonise’ EE while exploring its limits. I shall begin by presenting two ways of integrating a Darwinian way of thinking into the context of social and political sciences : Social Darwinism and what one could label ‘Pro-social Darwinism’. Next I will point out some of the fundamental errors on which Social Darwinism is grounded; this will help in understanding why contemporary evolutionary ethicists cannot possibly hold the views defended by this theory (unless they are inclined to intellectual dishonesty). On the contrary, EE seems more akin to a Pro-social Darwinian approach, except for the fact that it restricts its reflections to theoretical ethics. The second part of the paper (sections 3 to 7) provides a clear and detailed picture of EE as well as an analysis of its relevance at the different levels of ethics (descriptive, meta-, normative and practical). Special focus will be given to questions relating to the genesis of morals and the delicate shift from facts to norms. (shrink)
We consider how to discern whether or not evolution is taking place in an observed system. Evolution will be characterized in terms of a particular macroscopic behavior that emerges from microscopic organismic interaction. We de ne evolutionary activity as the rate at which useful genetic innovations are absorbed into the population. After measuring evolutionary activity in a simple model biosphere, we discuss applications to other systems. We argue that evolutionary activity provides an objective, quantitative interpretation of (...) the intuitive idea of biological teleology. We also propose using evolutionary activity in a test for life. (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? In this chapter we apply this argument to beliefs in three different domains: morality, religion, and science. We identify replies to evolutionary scepticism that work in some domains but not in others. The simplest reply to evolutionary scepticism is that the truth (...) of beliefs in a certain domain is, in fact, connected to evolutionary success, so that evolution can be expected to design systems that produce true beliefs in that domain. We call a connection between truth and evolutionary success a ‘Milvian bridge’, after the tradition which ascribes the triumph of Christianity at the battle of the Milvian bridge to the truth of Christianity. We argue that a Milvian bridge can be constructed for commonsense beliefs, and extended to scientific beliefs, but not to moral and religious beliefs. An alternative reply to evolutionary scepticism, which has been used defend moral beliefs, is to argue that their truth does not depend on their tracking some external state of affairs. We ask if this reply could be used to defend religious beliefs. (shrink)
Evolutionary debunkers of morality hold this thesis: If S’s moral belief that P can be given an evolutionary explanation, then S’s moral belief that P is not knowledge. In this paper, I debunk a variety of arguments for this thesis. I first sketch a possible evolutionary explanation for some human moral beliefs. Next, I explain how, given a reliabilist approach to warrant, my account implies that humans possess moral knowledge. Finally, I examine the debunking arguments of Michael (...) Ruse, Sharon Street, and Richard Joyce. I draw on the account of moral knowledge sketched earlier to illustrate how these arguments fail. -/- . (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.

Alvin Plantinga has argued that evolutionary naturalism (the idea that God does not tinker with evolution) undermines its own rationality. Natural selection is concerned with survival and reproduction, and false beliefs conjoined with complementary motivational drives could serve the same aims as true beliefs. Thus, argues Plantinga, if we believe we evolved naturally, we should not think our beliefs are, on average, likely to be true, including our beliefs in evolution and naturalism. I argue herein that our cognitive faculties (...) are less reliable than we often take them to be, that it is theism which has difficulty explaining the nature of our cognition, that much of our knowledge is not passed through biological evolution but learned and transferred through culture, and that the unreliability of our cognition helps explain the usefulness of science.

It is commonly suggested that evolutionary considerations generate an epistemological challenge for moral realism. At first approximation, the challenge for the moral realist is to explain our having many true moral beliefs, given that those beliefs are the products of evolutionary forces that would be indifferent to the moral truth. An important question surrounding this challenge is the extent to which it generalizes. In particular, it is of interest whether the Evolutionary Challenge for moral realism is equally (...) a challenge for mathematical realism. It is widely thought not to be. In this paper, I argue that the Evolutionary Challenge for moral realism is equally a challenge for mathematical realism. Along the way, I substantially clarify the Evolutionary Challenge, discuss its relation to more familiar epistemological challenges, and broach a number of foundational issues in metaphysics. The paper should be of interest to ethicists because it places pressure on anyone who rejects moral realism on the basis of the Evolutionary Challenge to reject mathematical realism as well. And the paper should be of interest to philosophers of mathematics because it presents a new epistemological challenge for mathematical realism that bears, I argue, no simple relation to Paul Benacerraf's familiar challenge.

Evolutionary psychologists claim that the mind contains “hundreds or thousands” of “genetically specified” modules, which are evolutionary adaptations for their cognitive functions. We argue that, while the adult human mind/brain typically contains a degree of modularization, its “modules” are neither genetically specified nor evolutionary adaptations. Rather, they result from the brain’s developmental plasticity, which allows environmental task demands a large role in shaping the brain’s information-processing structures. The brain’s developmental plasticity is our fundamental psychological adaptation, and the (...) “modules” that result from it are adaptive responses to local conditions, not past evolutionary environments. If different individuals share common environ- ments, however, they may develop similar “modules,” and this process can mimic the development of genetically specified modules in the evolutionary psychologist’s sense.

Despite their divergent metaphysical assumptions, Reformed and evolutionary epistemologists have converged on the notion of proper basicality. Where Reformed epistemologists appeal to God, who has designed the mind in such a way that it successfully aims at the truth, evolutionary epistemologists appeal to natural selection as a mechanism that favors truth-preserving cog- nitive capacities. This paper investigates whether Reformed and evolutionary epistemological accounts of theistic belief are compatible. We will argue that their chief incompatibility lies in the (...) noetic effects of sin and what may be termed the noetic effects of evolution, systematic tendencies wherein human cognitive faculties go awry. We propose a reconceptualization of the noetic effects of sin to mitigate this tension. (shrink)
Evolutionary psychology and social constructionism are widely regarded as fundamentally irreconcilable approaches to the social sciences. Focusing on the study of the emotions, we argue that this appearance is mistaken. Much of what appears to be an empirical disagreement between evolutionary psychologists and social constructionists over the universality or locality of emotional phenomena is actually generated by an implicit philosophical dispute resulting from the adoption of different theories of meaning and reference. We argue that once this philosophical dispute (...) is recognized, it can be set to the side. When this is done, it becomes clear that the two approaches to the emotions complement, rather than compete with, one another. (shrink)
Both Popper and van Fraassen have used evolutionary analogies to defend their views on the aim of science, although these are diametrically opposed. By employing Price's equation in an illustrative capacity, this paper considers which view is better supported. It shows that even if our observations and experimental results are reliable, an evolutionary analogy fails to demonstrate why conjecture and refutation should result in: (1) the isolation of true theories; (2) successive generations of theories of increasing truth-likeness; (3) (...) empirically adequate theories; or (4) successive generations of theories of increasing proximity to empirical adequacy. Furthermore, it illustrates that appeals to induction do not appear to help. It concludes that an evolutionary analogy is only sufficient to defend the notion that the aim of science is to isolate a particular class of false theories, namely those that are empirically inadequate.

I argue that evolutionary strategies of kin selection and game-theoretic reciprocity are apt to generate agent-centered and agent- neutral moral intuitions, respectively. Such intuitions are the building blocks of moral theories, resulting in a fundamental schism between agent-centered theories on the one hand and agent-neutral theories on the other. An agent-neutral moral theory is one according to which everyone has the same duties and moral aims, no matter what their personal interests or interpersonal relationships. Agent-centered moral theories deny this (...) and include at least some prescriptions that include ineliminable indexicals. I argue that there are no rational means of bridging the gap between the two types of theories; nevertheless this does not necessitate skepticism about the moral—we might instead opt for an ethical relativism in which the truth of moral statements is relativized to the perspective of moral theories on either side of the schism. Such a relativism does not mean that any ethical theory is as good as any other; some cannot be held in reflective equilibrium, and even among those that can, there may well be pragmatic reasons that motivate the selection of one theory over another. But if no sort of relativism is deemed acceptable, then it is hard to avoid moral skepticism. (shrink)
Evolutionary theory is undergoing an intense period of discussion and reevaluation. This, contrary to the misleading claims of creationists and other pseudoscientists, is no harbinger of a crisis but rather the opposite: the field is expanding dramatically in terms of both empirical discoveries and new ideas. In this essay I briefly trace the conceptual history of evolutionary theory from Darwinism to neo-Darwinism, and from the Modern Synthesis to what I refer to as the Extended Synthesis, a more inclusive (...) conceptual framework containing among others evo–devo, an expanded theory of heredity, elements of complexity theory, ideas about evolvability, and a reevaluation of levels of selection. I argue that evolutionary biology has never seen a paradigm shift, in the philosophical sense of the term, except when it moved from natural theology to empirical science in the middle of the 19th century. The Extended Synthesis, accordingly, is an expansion of the Modern Synthesis of the 1930s and 1940s, and one that—like its predecessor—will probably take decades to complete. (shrink)
The naturalistic fallacy is mentionedfrequently by evolutionary psychologists as anerroneous way of thinking about the ethicalimplications of evolved behaviors. However,evolutionary psychologists are themselvesconfused about the naturalistic fallacy and useit inappropriately to forestall legitimateethical discussion. We briefly review what thenaturalistic fallacy is and why it is misusedby evolutionary psychologists. Then we attemptto show how the ethical implications of evolvedbehaviors can be discussed constructivelywithout impeding evolutionary psychologicalresearch. A key is to show how ethicalbehaviors, in addition to unethical behaviors,can (...) evolve by natural selection. (shrink)
In Chapter Five of The Mind Doesn’t Work That Way, Jerry Fodor argues that since it is likely that human minds evolved quickly as saltations rather than gradually as the product of an accumulation of small mutations, evolutionary psychologists are wrong to think that human minds are adaptations. I argue that Fodor’s requirement that adaptationism entails gradualism is wrongheaded. So, while evolutionary psychologists may be wrong to endorse gradualism—and I argue that they are wrong—it does not follow that (...) they are wrong to endorse an adaptationist explanation for how the human mind evolved.

The idea of phenotypic novelty appears throughout the evolutionary literature. Novelties have been defined so broadly as to make the term meaningless and so narrowly as to apply only to a limited number of spectacular structures. Here I examine some of the available definitions of phenotypic novelty and argue that the modern synthesis is ill equipped at explaining novelties. I then discuss three frameworks that may help biologists get a better insight of how novelties arise during evolution but warn (...) that these frameworks should be considered in addition to, and not as potential substitutes of, the modern synthesis. †To contact the author, please write to: Departments of Ecology and Evolution and Philosophy, Stony Brook University, Stony Brook, NY 11794; e‐mail: pigliucci@platofootnote.org.

Evolutionary Psychology is based on the idea that the mind is a set of special purpose thinking devices or modules whose domain-specific structure is an adaptation to ancestral environments. The modular view of the mind is an uncontroversial description of the periphery of the mind, the input-output sensorimotor and affective subsystems. The novelty of EP is the claim that higher order cognitive processes also exhibit a modular structure. Autism is a primary case study here, interpreted as a developmental failure (...) of a module devoted to social intelligence or Theory of Mind. In this article I reappraise the arguments for innate modularity of TOM and argue that they fail. TOM ability is a consequence of domain general development scaffolded by early, innately specified, sensorimotor abilities. The alleged Modularity of TOM results from interpreting the outcome of developmental failures characteristic of autism at too high a level of cognitive abstraction. (shrink)
It seems impossible that organisms selected to maximize their genetic legacy could also be moral agents in a world in which taking risks for strangers is sometimes morally laudable. Brian Zamulinski argues that it is possible if morality is an evolutionary by-product rather than an adaptation.Evolutionary Intuitionism presents a new evolutionary theory of human morality. Zamulinski explains the evolution of foundational attitudes, whose relationships to acts constitute moral facts. With foundational attitudes and the resulting moral facts in (...) place, he shows how they ground a plausible normative morality, give answers to meta-ethical questions, and provide an account of moral motivation. He explains the nature of moral intuitions and, thus, of our access to the moral facts. He shows that the theory makes confirmed empirical predictions, including the observable variation in moral views. The combination of intuitionism and evolutionary ethics enables Zamulinski to overcome the standard objections to both.Evolutionary Intuitionism is a unified theory of human morality that explains how an objective morality could develop naturally in a physical world like ours, among organisms like us.

Evolutionary psychology is widely understood as involving an integration of evolutionary theory and cognitive psychology, in which the former promises to revolutionise the latter. In this paper, I suggest some reasons to doubt that the assumptions of evolutionary theory and of cognitive psychology are as directly compatible as is widely assumed. These reasons relate to three different problems of specifying adaptive functions as the basis for characterising cognitive mechanisms: the disjunction problem, the grain problem and the environment (...) problem. Each of these problems can be understood as arising from incommensurate characterisations of the nature and role of 'the environment' in the two approaches. Purported solutions to the problems appear to require detailed information concerning the EEA (environment of evolutionary adaptedness), with the disjunction problem placing the lowest requirement, the environment problem placing the highest requirement, and the grain problem placing an intermediate one. In each case, such information is not likely to be forthcoming, because it may require iterating through successively more distant EEA's with no principled stopping point. This produces a dilemma for evolutionary psychology - either to solve these apparently insoluble problems, or to attempt to avoid them but in doing so forego detailed evolutionary constraints on cognition.

Proponents of evolutionary psychology take the existence of humanuniversals to constitute decisive evidence in favor of their view. Ifthe same social norms are found in culture after culture, we have goodreason to believe that they are innate, they argue. In this paper Ipropose an alternative explanation for the existence of humanuniversals, which does not depend on them being the product of inbuiltpsychological adaptations. Following the work of Brian Skyrms, I suggestthat if a particular convention possesses even a very small (...) advantageover competitors, whatever the reason for that advantage, we shouldexpect it to become the norm almost everywhere. Tiny advantages aretranslated into very large basins of attraction, in the language of gametheory. If this is so, universal norms are not evidence for innatepsychological adaptations at all. Having shown that the existence ofuniversals is consistent with the so-called Standard Social ScienceModel, I turn to a consideration of the evidence, to show that thisstyle of explanation is preferable to the evolutionary explanation, atleast with regard to patterns of gender inequality.

Elliott Sober is one of the leading philosophers of science and is a former winner of the Lakatos Prize, the major award in the field.

This paper outlines a critique of the use of the genetic variance–covariance matrix (G), one of the central concepts in the modern study of natural selection and evolution. Specifically, I argue that for both conceptual and empirical reasons, studies of G cannot be used to elucidate so-called constraints on natural selection, nor can they be employed to detect or to measure past selection in natural populations – contrary to what assumed by most practicing biologists. I suggest that the search for (...) a general solution to the difficult problem of identifying causal structures given observed correlation’s has led evolutionary quantitative geneticists to substitute statistical modeling for the more difficult, but much more valuable, job of teasing apart the many possible causes underlying the action of natural selection. Hence, the entire evolutionary quantitative genetics research program may be in need of a fundamental reconsideration of its goals and how they correspond to the array of mathematical and experimental techniques normally employed by its practitioners.

This article draws out an epistemological tension implicit in Cosmides and Tooby's conception of evolutionary psychology. Cosmides and Tooby think of the mind as a collection of functionally individuated, domain-specific modules. Although they do not explicitly deny the existence of domain-general processes, it will be shown that their methodology commits them to the assumption that only domain-specific cognitive processes are capable of producing useful outputs. The resultant view limits the scope of biologically possible cognitive accomplishments and these limitations, it (...) will be argued, are such as to deny us epistemic capacities that evolutionary psychology presupposes in its pursuit of an objective, comprehensive account of human nature.

According to David Chalmers, the hard problem of consciousness consists of explaining how and why qualitative experience arises from physical states. Moreover, Chalmers argues that materialist and reductive explanations of mentality are incapable of addressing the hard problem. In this chapter, I suggest that Chalmers’ hard problem can be usefully distinguished into a ‘how question’ and ‘why question,’ and I argue that evolutionary biology has the resources to address the question of why qualitative experience arises from brain states. From (...) this perspective, I discuss the different kinds of evolutionary explanations (e.g., adaptationist, exaptationist, spandrel) that can explain the origins of the qualitative aspects of various conscious states. This argument is intended to clarify which parts of Chalmers’ hard problem are amenable to scientific analysis. (shrink)
Evolutionary psychologists attempt to infer our evolved psychology from the selection pressures present in our ancestral environments. Their use of this inference strategy?often called ?adaptive thinking??is thought to be justified by way of appeal to a rather modest form of adaptationism, according to which the mind's adaptive complexity reveals it to be a product of selection. I argue, on the contrary, that the mind's being an adaptation is only a necessary and not a sufficient condition for the validity of (...) adaptive thinking, and that evolutionary psychology's predictive project is in fact committed to an extremely strong and highly implausible form of adaptationism. According to this ?strong adaptationism,? the macroevolutionary trajectory of a population is determined by, and therefore predictable on the basis of, the selection pressures acting upon it. Not only is this form of adaptationism prima facie highly implausible, it requires making a number of naïve and likely false assumptions concerning the nature of heritable phenotypic variation in natural populations. In particular, it assumes that phenotypic variation is inevitably small in its extent, unbiased in its direction, and copious in its quantity. Because it is unlikely that these conditions obtain as a general rule, and even more unlikely that they obtained in early human populations, I conclude that there is little reason to believe that adaptive thinking can be used to infer the current structure of our minds from evidence of past selection pressures.

This paper offers an evolutionary account of chronic pain. Chronic pain is a maladaptive by-product of pain mechanisms and neural plasticity, both of which are highly adaptive.

Evolutionary psychology is most promising when it adopts a bottom-up research strategy that focuses on (...) basic affective and motivational systems (as opposed to higher cognitive functions) that are phylogenetically deep.

The Modern Synthesis (MS) is the current paradigm in evolutionary biology. It was actually built by expanding on the conceptual foundations laid out by its predecessors, Darwinism and neo-Darwinism. For sometime now there has been talk of a new Extended Evolutionary Synthesis (EES), and this article begins to outline why we may need such an extension, and how it may come about. As philosopher Karl Popper has noticed, the current evolutionary theory is a theory of genes, and (...) we still lack a theory of forms. The field began, in fact, as a theory of forms in Darwin’s days, and the major goal that an EES will aim for is a unification of our theories of genes and of forms. This may be achieved through an organic grafting of novel concepts onto the foundational structure of the MS, particularly evolvability, phenotypic plasticity, epigenetic inheritance, complexity theory, and the theory of evolution in highly dimensional adaptive landscapes.

The idea of genetic assimilation, that environmentally induced phenotypes may become genetically fixed and no longer require the original environmental stimulus, has had varied success through time in evolutionary biology research. Proposed by Waddington in the 1940s, it became an area of active empirical research mostly thanks to the efforts of its inventor and his collaborators. It was then attacked as of minor importance during the ‘‘hardening’’ of the neo-Darwinian synthesis and was relegated to a secondary role for decades. (...) Recently, several papers have appeared, mostly independently of each other, to explore the likelihood of genetic assimilation as a biological phenomenon and its potential importance to our understanding of evolution. In this article we briefly trace the history of the concept and then discuss theoretical models that have newly employed genetic assimilation in a variety of contexts. We propose a typical scenario of evolution of genetic assimilation via an intermediate stage of phenotypic plasticity and present potential examples of the same. We also discuss a conceptual map of current and future lines of research aimed at exploring the actual relevance of genetic assimilation for evolutionary biology. (shrink)
The so-called evolutionary approach is getting more and more popular in various branches of philosophy. Evolutionary explanations are often used in virtually every classical philosophical discipline. The structure of evolutionary explanations is examined and it is pointed out that only one sub-category of evolutionary explanations, namely, nonreductive, non-stipulated adaptation-explanation can be of any philosophical significance. I finish by examining which of the proposed philosophical arguments use this kind of evolutionary explanation. The answer will be disappointing (...) for those who would like to think of philosophy as a branch of evolutionary biology. (shrink)
. Evolutionary psychology and behavioural genomics are both approaches to explain human behaviour from a genetic point of view. Nonetheless, thus far the development of these disciplines is anything but interdependent. This paper examines the question whether evolutionary psychology can contribute to behavioural genomics. Firstly, a possible inconsistency between the two approaches is reviewed, viz. that evolutionary psychology focuses on the universal human nature and disregards the genetic variation studied by behavioural genomics. Secondly, we will discuss the (...) structure of biological explanations. Some philosophers rightly acknowledge that explanations do not involve laws which are exceptionless and universal. Instead, generalisations that are invariant suffice for successful explanation as long as two other stipulations are recognised: the domain within which the generalisation has no exceptions as well as the distribution of the mechanism described by the generalisation should both be specified. It is argued that evolutionary psychology can contribute to behavioural genomic explanations by accounting for these two specifications. (shrink)
Recent debate in metaethics over evolutionary debunking arguments against morality has shown a tendency to abstract away from relevant empirical detail. Here, I engage the debate about Darwinian debunking of morality with relevant empirical issues.

I then argue that these conditions are not met in the case of our (...) evolved faculty for moral judgement. (shrink)
Research in ecology and evolutionary biology (evo-eco) often tries to emulate the “hard” sciences such as physics and chemistry, but to many of its practitioners feels more like the “soft” sciences of psychology and sociology. I argue that this schizophrenic attitude is the result of lack of appreciation of the full consequences of the peculiarity of the evo-eco sciences as lying in between a-historical disciplines such as physics and completely historical ones as like paleontology. Furthermore, evo-eco researchers have gotten (...) stuck on mathematically appealing but philosophi- cally simplistic concepts such as null hypotheses and p-values defined according to the frequentist approach in statistics, with the consequence of having been unable to fully embrace the complexity and subtlety of the problems with which ecologists and evolutionary biologists deal with. I review and discuss some literature in ecology, philosophy of science and psychology to show that a more critical methodological attitude can be liberating for the evo-eco scientist and can lead to a more fecund and enjoyable practice of ecology and evolutionary biology. With this aim, I briefly cover concepts such as the method of multiple hypotheses, Bayesian analysis, and strong inference. (shrink)
Aspects of the history of behavioural science are reviewed, pointing to its fragmented and faction-ridden nature. The emergence of evolutionary psychology (EP) is viewed in this context. With the help of a dual-layered model of behavioural control, the case is made for a more integrative perspective towards EP. The model's application to both behaviour and complex human information processing is described. Similarities in their control are noted. It is suggested that one layer of control (‘on-line’) corresponds to the encapsulated (...) modules of EP whereas the off-line controls provide the plasticity and flexibility suggested by its critics.

Evolutionary Naturalism is a collection of interconnected essays on the history and philosopy of evolutionary biology written by the influential Canadian philosopher, Michael Ruse. In this book, he argues that the time has arrived to take philosophy out of the hands of the academic theorists and to fully embrace the findings and consequences of the modern sciences. These clearly written essays cover a broad range of key topics in the philosophy of science. Michael Ruse discusses several issues in (...) the history of science including Darwinism, population biology, and the paleo-ontological theory of `punctuated equilibria'. In addition, he expounds an epistemological theory which argues that our knowledge of the external world is informed by the fact that we ar evolved beings, rather than objects of special creation. Ruse maintains that our evolved state must affect our knowledge and perception of the world in which we live. Evolutionary Naturalism also contains a fierce critique of ethical systems which are rendered as no more than biologically determined collective illusions. In Evolutionary Materialism Michael Ruse forges a path between the crude objectivity espoused by many working scientists and the relativism of post-modern critiques of science. Written in a clear and non-technical style, this book provides valuable material for all those interested in the relationship between science and philosophy in the modern world. (shrink)
This paper develops an account of evolutionary progress for use in the field of evolutionary economics. Previous work is surveyed and a new account set out, based on the idea of evolvability as it has been used recently in evolutionary developmental biology. The biological underpinnings of this idea are explained using examples of a series of phenomena that influence the evolvability of biological systems. It is further argued that selection pressures and developmental processes are sufficiently similar to (...) make this biological concept useful in economics. The new account is defended against a number of common objections to the notion of progress in evolving systems, including the claim that all stipulated measures of evolutionary progress are essentially arbitrary. It is argued that progress, understood as an increase in evolvability over time, is both philosophically well-justified and provides useful predictive and explanatory resources to those seeking to understand and manipulate evolving economic systems.

Evolutionary psychology and the selectionist theories of neural development are usually regarded as two unrelated theories addressing two logically distinct questions. The focus of evolutionary psychology is the phylogeny of the human mind, whereas the selectionist theories of neural development analyse the ontogeny of the mind. This paper will endeavour to combine these two approaches in the explanation of the human mind. Doing so might help in overcoming some of the criticisms of both theories. The first part of (...) the paper mentions three standard objections to evolutionary psychology and then outlines three philosophical problems evolutionary psychology has to offer a solution to. The second part will try to show that an approach combining evolutionary psychology and the selectionist theory of neural development might overcome some of these objections. (shrink)
The joke among scientists is that ‘philosopher’ is the last stage of one’s scien- tific career, to be arrived at when one can no longer get grants funded or graduate stu- dents to advise. Despite the fact that some of the greatest minds in evolutionary biology (from Darwin to Ernst Mayr) were very much interested in the philosophical aspects of what they were doing, the bad joke persists in the halls of academia.
The development of modern evolutionary ethics began shortly after the publication of Charles Darwin's On the Origin of Species by Natural Selection. Early discussions were plagued by several problems. First, evolutionary ethical explanations were dependent on group-selection accounts of social behavior (especially the explanation of altruism). Second, they seem to violate the philosophical principle that “ought” statements cannot be derived from “is” statements alone (values cannot be derivedfrom facts alone). Third, evolutionary ethics appeared to be biologically deterministic, (...) deemed incompatible with the free will required for ethics to be possible. Fourth, social policies based on evolutionary theory (for example, eugenics in the early part of this century) seemed patently unethical. Sociobiology (which coalesced as a field of study with Edward O. Wilson's Sociobiology: The New Synthesis, 1975) addressed several of these problems and provided a rich framework and a new impetus for evolutionary ethics. The lingering problems were the philosophical is-ought barrier and biological determinism. After tracing the early and more recent development of evolutionary ethics, I argue that the remaining problems can be surmounted and an incipient evolutionary ethics can be defended. Thoroughgoing evolutionaryethics must await theoretical developments in neurobiology and cognitive science. (shrink)
This essay reviews one of the most recent books in a trend of new publications proffering evolutionary theorising about aesthetics and the arts—themes within an increasing literature on aspects of human life and human nature in terms of evolutionary theory. Stephen Davies’ The Artful Species links some of our aesthetic sensibilities with our evolved human nature and critically surveys the interdisciplinary debate regarding the evolutionary status of the arts. Davies’ engaging and accessible writing succeeds in demonstrating the (...) maturity and scope of the field and his critique is timely and unparalleled. A laudable effort, however it may have benefited from espousing a co-evolutionary model more explicitly. Moreover there may be reason to question the usefulness of the standard set of distinctions (‘adaptation’, ‘spandrel’, ‘technology’) that Davies appeals to. (shrink)
Making Sense of Evolution explores contemporary evolutionary biology, focusing on the elements of theories—selection, adaptation, and species—that are complex and open to multiple possible interpretations, many of which are incompatible with one another and with other accepted practices in the discipline. Particular experimental methods, for example, may demand one understanding of “selection,” while the application of the same concept to another area of evolutionary biology could necessitate a very different definition.
In this book, Weikart helps unlock the mystery of Hitler’s evil by vividly demonstrating the surprising conclusion that Hitler’s immorality flowed from a coherent ethic. Hitler was inspired by evolutionary ethics to pursue the utopian project of biologically improving the human race. This ethic underlay or influenced almost every major feature of Nazi policy: eugenics (i.e., measures to improve human heredity, including compulsory sterilization), euthanasia, racism, population expansion, offensive warfare, and racial extermination.
The Narrow Evolutionary Psychology Movement represents itself as a major reorientation of the social/behavioral sciences, a group of sciences previously dominated by something called the ‘Standard Social Science Model’ (SSSM; Cosmides, Tooby, and Barkow, 1992). Narrow Evolutionary Psychology alleges that the SSSM treated the mind, and particularly those aspects of the mind that exhibit cultural variation, as devoid of any marks of its evolutionary history. Adherents of Narrow Evolutionary Psychology often suggest that the SSSM owed more (...) to ideology than to evidence. It was the child of the 1960s, representing a politically motivated insistence on the possibility of changing social arrangements such as gender roles:
‘Not so long ago jealousy was considered a pointless, archaic institution in need of reform. But like other denials of human nature from the 1960s, this bromide has not aged well.’ (Stephen Pinker, endorsement for Buss, 2000))
This view of history does not ring true to those, like the authors, who have worked in traditions of evolutionary theorizing about the mind that have a continuous history through the 1960s and beyond: traditions such as evolutionary epistemology (Stotz, 1996; Callebaut and Stotz, 1998) and psychoevolutionary research into emotion (Griffiths.

This paper evaluates the claim that it is possible to use nature’s variation in conjunction with retention and selection on the one hand, and the absence of ultimate groundedness of hypotheses generated by the human mind as it knows on the other hand, to discard the ascription of ultimate certainty to the rationality of human conjectures in the cognitive realm. This leads to an evaluation of the further assumption that successful hypotheses with specific applications, in other words heuristics, seem to (...) have a firm footing because they were useful in another context. I argue that usefulness evaluated through adaptation misconstrues the search for truth, and that it is possible to generate talk of randomness by neglecting aspects of a system’s insertion into a larger situation. The framing of the problem in terms of the elimination of unfit hypotheses is found to be unsatisfying. It is suggested that theories exist in a dimension where they can be kept alive rather than dying as phenotypes do. The proposal that the subconscious could suggest random variations is found to be a category mistake. A final appeal to phenomenology shows that this proposal is orphan in the history of epistemology, not in virtue of its being a remarkable find, but rather because it is ill-conceived. (shrink)
In the fall of 1990 I had just began my doc- toral studies at the University of Connecticut. Freshly arrived from Italy, I came to the United States to work with Carl Schlichting on something to do with phenotypic plastic- ity. I spent most of that semester discussing with other graduate students what I thought was a momentous paper by Mary Jane West- Eberhard (1989) in the Annual Review of Ecol- ogy and Systematics. That paper, entitled Phe- notypic Plasticity and (...) the Origins of Diversity, was a (quite lengthy) forerunner of the (also quite bulky) book I am reviewing now. Like the paper, this volume has the potential to be momentous in the development of our ideas on phenotypic evolution. (shrink)

The notion of development has been permeated by concepts and methods from positivistic science. As a result, many development initiatives are reductionistic, myopic, and with little or impact on the improvement of the quality of life and the sustainability of communities and societies. This article marks the beginning of a transdisciplinary inquiry among the authors, motivated by direct interest in the issue of development, per se, and in particular, Mexico's development. Our inquiry departs from and weaves together our various areas (...) of expertise and experience, including: systems theory, general evolution theory, economic development, technology transfer, social innovation, sustainable development, environmental behavior, social systems design, and education. The article reviews the concept of development from an evolutionary and systemic perspective. It outlines the foundations of evolutionary development in terms of theory, philosophy, and methodology and provides a conceptual framework for future research aimed at the articulation of a practical model for evolutionary development.

With Carl Gegenbaur and Ernst Haeckel, inspiredby Darwin and the cell theory, comparativeanatomy and embryology became established andflourished in Jena. This tradition wascontinued and developed further with new ideasand methods devised by some of Haeckelsstudents. This first period of innovative workin evolutionary morphology was followed byperiods of crisis and even a disintegration ofthe discipline in the early twentieth century.This stagnation was caused by a lack ofinterest among morphologists in Mendeliangenetics, and uncertainty about the mechanismsof evolution. Idealistic morphology was stillinfluental (...) in Germany, which prevented a fullappreciation of the importance of Darwinstheory of natural selection for comparativemorphology. Evolutionary morphology andembryology failed to contribute significantlyto the modern synthesis of evolutionarybiology, thereby probably delaying theintegration of developmental biology intomodern evolutionary biology. However, Haeckelsstudent Oscar Hertwig, as well as Victor Franzand Alexej N. Sewertzoff from a youngergeneration, all tried to forge their ownsynthetic approaches in which (inspired byHaeckels work) embryology played an importantrole. Important for all three researchers wereattempts to refine, and sometimes redefine, thebiogenetic law, and to find new scientificexplanations for it (and for the manyexceptions to it). Their research was latermore or less forgotten, and had littleinfluence on the architects of the modernsynthesis. As the relationship betweenevolutionary and developmental biology is nowagain rising in importance in the form ofEvo-Devo, we would like to draw attention tohow this earlier research tradition grappledwith similar questions to those now on theagenda, albeit from sometimes quite differentperspectives.

Evolutionary debunking arguments (EDAs) are arguments that appeal to the evolutionary origins of evaluative beliefs to undermine their justification. This paper aims to clarify the premises and presuppositions of EDAs—a form of argument that is increasingly put to use in normative ethics. I argue that such arguments face serious obstacles. It is often overlooked, for example, that they presuppose the truth of metaethical objectivism. More importantly, even if objectivism is assumed, the use of EDAs in normative ethics is (...) incompatible with a parallel and more sweeping global evolutionary debunking argument that has been discussed in recent metaethics. After examining several ways of responding to this global debunking argument, I end by arguing that even if we could resist it, this would still not rehabilitate the current targeted use of EDAs in normative ethics given that, if EDAs work at all, they will in any case lead to a truly radical revision of our evaluative outlook.

Several theories claim that dreaming is a random by-product of REM sleep physiology and that it does not serve any natural function. Phenomenal dream content, however, is not as disorganized as such views imply. The form and content of dreams is not random but organized and selective: during dreaming, the brain constructs a complex model of the world in which certain types of elements, when compared to waking life, are underrepresented whereas others are over represented. Furthermore, dream content is consistently (...) and powerfully modulated by certain types of waking experiences. On the basis of this evidence, I put forward the hypothesis that the biological function of dreaming is to simulate threatening events, and to rehearse threat perception and threat avoidance. To evaluate this hypothesis, we need to consider the original evolutionary context of dreaming and the possible traces it has left in the dream content of the present human population. In the ancestral environment human life was short and full of threats. Any behavioral advantage in dealing with highly dangerous events would have increased the probability of reproductive success. A dream-production mechanism that tends to select threatening waking events and simulate them over and over again in various combinations would have been valuable for the development and maintenance of threat-avoidance skills. Empirical evidence from normative dream content, children's dreams, recurrent dreams, nightmares, post traumatic dreams, and the dreams of hunter-gatherers indicates that our dream-production mechanisms are in fact specialized in the simulation of threatening events, and thus provides support to the threat simulation hypothesis of the function of dreaming. Key Words: dream content; dream function; evolution of consciousness; evolutionary psychology; fear; implicit learning; nightmares; rehearsal; REM; sleep; threat perception. (shrink)
According to some recent arguments, (Joyce in The evolution of morality, MIT Press, Cambridge, 2006; Ruse and Wilson in Conceptual issues in evolutionary biology, MIT Press, Cambridge, 1995; Street in Philos Studies 127: 109–166, 2006) if our moral beliefs are products of natural selection, then we do not have moral knowledge. In defense of this inference, its proponents argue that natural selection is a process that fails to track moral facts. In this paper, I argue that our having moral (...) knowledge is consistent with, (a) the hypothesis that our moral beliefs are products of natural selection, and (b) the claim (or a certain interpretation of the claim) that natural selection fails to track moral facts. I also argue that natural selection is a process that could track moral facts, albeit imperfectly. I do not argue that we do have moral knowledge. I argue instead that Darwinian considerations provide us with no reason to doubt that we do, and with some reasons to suppose that we might. (shrink)
The dichotomy between Nature and Nurture, which has been dismantled within the framework of development, remains embodied in the notions of plasticity and evolvability. We argue that plasticity and evolvability, like development and heredity, are neither dichotomous nor distinct: the very same mechanisms may be involved in both, and the research perspective chosen depends to a large extent on the type of problem being explored and the kinds of questions being asked. Epigenetic inheritance leads to transgenerationally extended plasticity, and developmentally-induced (...) heritable epigenetic variations provide additional foci for selection that can lead to evolutionary change. Moreover, hereditary innovations may result from developmentally induced large-scale genomic repatterning events, which are akin to Goldschmidtian “systemic mutations”. The epigenetic mechanisms involved in repatterning can be activated by both environmental and genomic stress, and lead to phylogenetic as well as ontogenetic changes. Hence, the effects and the mechanisms of plasticity directly contribute to evolvability. (shrink)
In the second half of their recent, critically acclaimed book Unto Others: The Evolution and Psychology of Unselfish Behavior , Elliott Sober and David Sloan Wilson discuss psychological hedonism. This is the view that avoiding our own pain and increasing our own pleasure are the only ultimate motives people have. They argue that none of the traditional philosophical arguments against this view are good, and they go on to present theirownevolutionary biological argument against it. Interestingly, the first half of their (...) book, which is a defense of group selectionism, has received almost all of the attention of those people who have published reactions to the book. No one has published a detailed reaction to the argument of the latter half of the book. In this article, the author explains and critically discusses their evolutionary biological argument against psychological hedonism, concluding that in its current form it is not strong enough to support its conclusion. However, the author goes on to argue that despite recent criticisms of Robert Nozick’s experience-machine argument, it is still a good argument against psychological hedonism. In support of the latter point, the author responds to the objections of Sober and Wilson and to the more recent criticisms offered by Matthew Silverstein. Key Words: hedonism • psychological egoism • evolution • Robert Nozick • Elliott Sober. (shrink)
Recent years have witnessed a ground swell of interest in the application of evolutionary theory to issues in psychopathology (Nesse & Williams 1995, Stevens & Price 1996, McGuire & Troisi 1998). Much of this work has been aimed at finding adaptationist explanations for a variety of mental disorders ranging from phobias to depression to schizophrenia. There has, however, been relatively little discussion of the implications that the theories proposed by evolutionary psychologists might have for the classification of mental (...) disorders. This is the theme we propose to explore. We'll begin, in Section 2, by providing a brief overview of the account of the mind advanced by evolutionary psychologists. In Section 3 we'll explain why issues of taxonomy are important and why the dominant approach to the classification of mental disorders is radically and alarmingly unsatisfactory. We will also indicate why we think an alternative approach, based on theories in evolutionary psychology, is particularly promising. In Section 4 we'll try to illustrate some of the virtues of the evolutionary psychological approach to classification. The discussion in Section 4 will highlight a quite fundamental distinction between those disorders that arise from the malfunction of a component of the mind and those that can be traced to the fact that our minds must now function in environments that are very different from the environments in which they evolved. This mis-match between the current and ancestral environments can, we maintain, give rise to serious mental disorders despite the fact that, in one important sense, there is nothing at all wrong with the people suffering the disorder. Their minds are functioning exactly as Mother Nature intended them to. In Section 5, we'll give a brief overview of some of the ways in which the sorts of malfunctions catalogued in Section 4 might arise, and sketch two rather different strategies for incorporating this etiologically.

In this paper, I critically summarize John Cartwrtight’s Evolution and Human Behavior and evaluate what he says about certain moral implications of Darwinian views of human behavior. He takes a Darwinism-doesn’t-rock-the-boat approach and argues that Darwinism, even if it is allied with evolutionary psychology, does not give us reason to be worried about the alterability of our behavior, nor does it give us reason to think that we may have to change our ordinary practices and views concerning free-will and (...) moral responsibility. In response, I contend that Darwinism, when it is allied with evolutionary psychology, makes for a more potent cocktail than Cartwright suspects. (shrink)
In their book Unto Others, Sober and Wilson argue that various evolutionary considerations (based on the logic of natural selection) lend support to the truth of psychological altruism. However, recently, Stephen Stich has raised a number of challenges to their reasoning: in particular, he claims that three out of the four evolutionary arguments they give are internally unconvincing, and that the one that is initially plausible fails to take into account recent findings from cognitive science and thus leaves (...) open a number of egoistic responses. These challenges make it necessary to reassess the plausibility of Sober & Wilson’s evolutionary account—which is what I aim to do in this paper. In particular, I try to show that, as a matter of fact, Sober & Wilson’s case remains compelling, as some of Stich’s concerns rest on a confusion, and those that do not are not sufficiently strong to establish all the conclusions he is after. The upshot is that no reason has been given to abandon the view that evolutionary theory has advanced the debate surrounding psychological altruism. (shrink)
Alvin Plantinga has famously argued that metaphysical naturalism is self-defeating, and cannot be rationally accepted. I distinguish between two different ways of understanding this argument, which I call the "probabilistic inference conception", and the "process characteristic conception". I argue that the former is what critics of the argument usually presuppose, whereas most critical responses fail when one assumes the latter conception. To illustrate this, I examine three standard objections to Plantinga's evolutionary argument against naturalism: the Perspiration Objection, the Tu (...) Quoque Objection, and the "Why Can't the Naturalist Just Add a Little Something?" Objection. I show that Plantinga's own responses to these objections fail, and propose counterexamples to his first two principles of defeat. I then go on to construct more adequate responses to these objections, using the distinctions I develop in the first part of the paper. (shrink)
Kuhn made two attempts at providing an evolutionary analogy for scientific change. The first attempt, in The Structure of Scientific Revolutions , is very brief and unstructured; in this article I discuss some of its weaknesses. Alexander Bird takes this attempt more seriously and provides a criticism based on oversimplified evolutionary assumptions. These assumptions prove to be inadequate for the second, more articulate, evolutionary analogy suggested by Kuhn in “The Road since Structure.” I argue, however, that this (...) second Kuhnian attempt is undermined by his inadequate view of biological progress and by his misunderstanding of the concept of ecological niche. *Received April 2008. †To contact the author, please write to: School of Politics, International Studies, and Philosophy, Queen’s University Belfast, 21 University Square, Belfast, BT7 1PA Northern Ireland; e‐mail: b.g.renzi@qub.ac.uk.

1. Evolutionary Moral Realism. On most contemporary approaches to evolution and ethics, morality is not a real part of the environment in which social and intelligent creatures evolve.1 According to such approaches, certain cooperative behavioural patterns develop, and thus become biologically real, but morality doesn’t become possible until creatures evolve a sophisticated enough cognitive ability to mistake the goals of such behavioural patterns for objective moral values. At a metaethical level, this line of thought has led evolutionary biologists (...) and moral philosophers alike to the conclusion that objective moral values are illusory. At an ethical level, the same line of thought has led most moral philosophers to suppose that evolutionary biology tells us nothing very important about ethics. Ethics is possible because of our evolutionary heritage as cooperative primates, but ethics itself only begins as we humans begin to talk, argue and reason about how we ought to live our lives together. With the standard view, we think morality is tied to cooperative behavioural patterns that.. (shrink)
Cognitive ethology is the comparative study of animal cognition from an evolutionary perspective. As a sub-discipline of biology it shares interest in questions concerning the immediate causes and development of behavior. As a part of ethology it is also concerned with questions about the function and evolution of behavior. I examine some recent work in cognitive ethology, and I argue that the notions of mental content and representation are important to enable researchers to answer questions and state generalizations about (...) the function and volution of behavior.

According to Aristotelian essentialism, the nature of an organism is constituted of a particular goal-directed disposition to produce an organism typical of its kind. This paper argues—against the prevailing orthodoxy—that essentialism of this sort is indispensable to evolutionary biology. The most powerful anti-essentialist arguments purport to show that the natures of organisms play no explanatory role in modern synthesis biology. I argue that recent evolutionary developmental biology provides compelling evidence to the contrary. Developmental biology shows that one must (...) appeal to the capacities of organisms to explain what makes adaptive evolution adaptive. Moreover, the specific capacities in question are precisely those that, according to Aristotle, constitute the nature of an organism.

Sober and Wilson have recently claimed that evolutionary theory can do what neither philosophy nor experimental psychology have been able to, namely, "break the deadlock" in the egoism vs. altruism debate with an argument based on the reliability of altruistic motivation.

I (...) expose the confusions that have led Sober and Wilson to defend a reliability argument while rejecting the experimental evidence of social psychology. (shrink)
This article identifies already existing theoretical and methodological commonalities between evolutionary biology and phenomenology, concentrating specifically on their common pursuit of origins. It identifies in passing theoretical support from evolutionary biology for present-day concerns in philosophy, singling out Sartre’s conception of fraternity as an example. It anchors its analysis of the common pursuit of origins in Husserl’s consistent recognition of the grounding significance of Nature and in his consistent recognition of animate forms of life other than human. It (...) enumerates and exemplifies five basic errors of continental philosophers with respect to Nature, errors testifying to a philosophical fundamentalism that distorts the intricate interconnections and relationships of Nature in favor of a preferred knowledge rooted in ontological reductionism. It shows that to discover and appreciate the common ground, one must indeed study “the things themselves.”. (shrink)
The Nature of Selection is a straightforward, self-contained introduction to philosophical and biological problems in evolutionary theory.

There are two interrelated but distinct programs which go by the name evolutionary epistemology. One attempts to account for the characteristics of cognitive mechanisms in animals and humans by a straightforward extension of the biological theory of evolution to those aspects or traits of animals which are the biological substrates of cognitive activity, e.g., their brains, sensory systems, motor systems, etc. (EEM program). The other program attempts to account for the evaluation of ideas, scientific theories and culture in general (...) by using models and metaphors drawn from evolutionary biology (EET program). The paper begins by distinguishing the two programs and discussing the relationship between them. The next section addresses the metaphorical and analogical relationship between evolutionary epistemology and evolutionary biology. Section IV treats the question of the locus of the epistemological problem in the light of an evolutionary analysis. The key questions here involve the relationship between evolutionary epistemology and traditional epistemology and the legitimacy of evolutionary epistemology as epistemology. Section V examines the underlying ontological presuppositions and implications of evolutionary epistemology. Finally, section VI, which is merely the sketch of a problem, addresses the parallel between evolutionary epistemology and evolutionary ethics. (shrink)
If, as the new tenseless theory of time maintains, there are no tensed facts, then why do our emotional lives seem to suggest that there are? This question originates with Prior’s ‘Thank Goodness That’s Over’ problem, and still presents a significant challenge to the new B-theory of time. We argue that this challenge has more dimensions to it than has been appreciated by those involved in the debate so far. We present an analysis of the challenge, showing the different questions (...) that a B-theorist must answer in order to meet it. The debate has focused on the question of what is the object of my relief when an unpleasant experience is past. We outline the prevailing response to this question. The additional, and neglected, questions are, firstly—‘Why does the same event elicit different emotional responses from us depending on whether it is in the past, present, or future?’ And secondly—‘Why do we care more about proximate future pain than about distant future pain?’ We give B-theory answers to these questions, which appeal to evolutionary considerations.

First, a brief history is provided of Popper's views on the status of evolutionary biology as a science. The views of some prominent biologists are then canvassed on the matter of falsifiability and its relation to evolutionary biology. Following that, I argue that Popper's programme of falsifiability does indeed exclude evolutionary biology from within the circumference of genuine science, that Popper's programme is fundamentally incoherent, and that the correction of this incoherence results in a greatly expanded and (...) much more realistic concept of what is empirical, resulting in the inclusion of evolutionary biology. Finally, this expanded concept of empirical is applied to two particular problems in evolutionary biology — viz., the species problem and the debate over the theory of punctuated equilibria — and it is argued that both of them are still mainly metaphysical.
