In recent controversies about Intelligent Design Creationism (IDC), the principle of methodological naturalism (MN) has played an important role. In this paper, an often neglected distinction is made between two different conceptions of MN, each with its respective rationale and with a different view on the proper role of MN in science. According to one popular conception, MN is a self-imposed or intrinsic limitation of science, which means that science is simply not equipped to deal with claims of the supernatural (...) (Intrinsic MN or IMN). Alternatively, we will defend MN as a provisory and empirically grounded attitude of scientists, which is justified in virtue of the consistent success of naturalistic explanations and the lack of success of supernatural explanations in the history of science (Provisory MN or PMN). Science does have a bearing on supernatural hypotheses, and its verdict is uniformly negative. We will discuss five arguments that have been proposed in support of IMN: the argument from the definition of science, the argument from lawful regularity, the science stopper argument, the argument from procedural necessity, and the testability argument. We conclude that IMN, because of its philosophical flaws, proves to be an ill-advised strategy to counter the claims of IDC. Evolutionary scientists are on firmer ground if they discard supernatural explanations on purely evidential grounds, instead of ruling them out by philosophical fiat. (shrink)

Buena parte de la elegancia del concepto de selección natural reside en una falsa aparienciade sencillez, y a menudo se expresa metafóricamente. En este artículo reviso diferentesmetáforas de la selección natural con el fin de revelar algunas complejidades ocultas. Enrealidad, el concepto de selección natural es un concepto difícil estrechamente relacionadocon otros conceptos complejos, tales como el concepto de eficacia biológica y de adaptación.Una discusión sobre las metáforas de la selección natural es pertinente porque la imagenque ellas evocan puede obstaculizar (...) la investigación del proceso natural al cual se refieren.

This paper examines the adequacy of an evolutionary-oriented notion of rationality—ecological rationality—that has recently been proposed in economics. Ecological rationality is concerned with what it is rational to do, and in this sense is a version of what philosophers call ‘practical rationality’. Indeed, the question of the adequacy of ecological rationality as it is understood in the paper, is the question of whether ecological rationality is a genuine notion of practical rationality. The paper first explicates and motivates the notion of (...) ecological rationality by (a) explicating the notion of practical rationality, (b) grounding ecological rationality in an evolutionary approach to the emotions which is mainly illustrated by the example of fear, and (c) outlining the reasons adduced in economics for generalizing ecological rationality beyond the emotions. The paper then argues that (d) the raison d’être of practical rationality is first and foremost a specific role it plays in the explanation of behavior, or in telling why it has occurred. Finally, based on (a)–(d), the paper argues that (e) ecological rationality lacks a constitutive feature of practical rationality—namely, normativity—which is related to the latter’s basic explanatory role, and thus cannot be considered a genuine notion of practical rationality. While the paper focuses on the economic version of ecological rationality, its conclusions apply just as well to other, related, versions of the ecological notion that have been proposed in biology and evolutionary psychology.

Jacob Klapwijk’s book Purpose in the Living World? (Cambridge 2998) is examined with special attention given to the scholarly background from out of which it emerges as a significant contribution to reformational philosophical reflection. As an initial step to clarify some important issues raised by Klapwijk’s critical comments about Dooyeweerd’s “essentialist” concept of species, the article probes facets of the way Jan Lever incorporated reformational philosophical concepts into his biological theory and considers the 1959 review written by Herman Dooyeweerd of (...) Lever’s Creation and Evolution. The analysis focuses specifically upon the social responsibilities of these two scholars and the confrontation of their respective views. With the work of Lever and Dooyeweerd we sense something of the ambiguities when reformational philosophy confronts an evangelical scholasticism. This confrontation is an important facet of the context in which Klapwijk has set forth his discussion of creation and emergent evolution. Purpose is also the fruit of scholarly collaboration across disciplines, providing a welcome stimulus for a deepened understanding of the corporate character of the student vocation. (shrink)

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)

The question whether ethical behavior is biologically determined may refer either to the capacity for ethics (i.e., the proclivity to judge human actions as either right or wrong), or to the moral norms accepted by human beings for guiding their actions. I herein propose: (1) that the capacity for ethics is a necessary attribute of human nature; and (2) that moral norms are products of cultural evolution, not of biological evolution. Humans exhibit ethical behavior by nature because their biological makeup (...) determines the presence of three necessary conditions for ethical behavior: (i) the ability to anticipate the consequences of one’s own actions; (ii) the ability to make value judgments; and (iii) the ability to choose between alternative courses of action. Ethical behavior came about in evolution not because it is adaptive in itself, but as a necessary consequence of man’s eminent intellectual abilities, which are an attribute directly promoted by natural selection. That is, morally evolved as an exaptation, not as an adaptation. Since Darwin’s time there have been evolutionists proposing that the norms of morality are derived from biological evolution. Sociobiologists represent the most recent and most subtle version of that proposal. The sociobiologists' argument is that human ethical norms are sociocultural correlates of behaviors fostered by biological evolution. I argue that such proposals are misguided and do not escape the naturalistic fallacy. The isomorphism between the behaviors promoted by natural selection and those sanctioned by moral norms exist only with respect to the consequences of the behaviors; the underlying causations are completely disparate.

Current Perspectives in Philosophy of Biology.

Classical pragmatism construed mind as an adaptive organ rooted in biology; biology was not one side and culture on the other. The cognitive systems underlie adaptation in response to the precarious and in the search for the stable and more secure that result in diverse forms of inquiry. Cognitive systems are rooted in action, and classical pragmatism knotted our sense of ourselves in response to nature and our cultural evolution. Cognitive systems should be demythologized away from Cartesian detachment, and towards (...) transactions with others and with nature. (shrink)

It is widely supposed that evolutionary debunking arguments against morality constitute a type of epistemological objection to our moral beliefs. In particular, the debunking force of such arguments is not supposed to depend on the metaphysical claim that moral facts do not exist. In this paper I argue that this standard epistemological construal of EDAs is highly misleading, if not mistaken. Specifically, I argue that the most widely discussed EDAs all make key and controversial metaphysical claims about the nature of (...) morality or the possibility of moral truth that belie their apparently epistemological character. I show that the debunking force of these EDAs derives largely from metaphysical claims about morality and their implications for the possibility of moral reduction, rather than from epistemological worries associated with the existence of an causal/non-moral explanation of our moral judgments. The paper briefly concludes with a dilemma that I believe confronts all EDAs such as those discussed in this paper: either such arguments are unsound, or else they prove too much, debunking our knowledge of science and the external world, as well as morality.

If the problem of the origin of life is conceptualized as a process of emergence of biochemistry from proto-biochemistry, which in turn emerged from the organic chemistry and geochemistry of primitive earth, then the resources of the new sciences of complex systems dynamics can provide a more robust conceptual framework within which to explore the possible pathways of chemical complexification leading to living systems and biosemiosis. In such a view the emergence of life, and concomitantly of natural selection and biosemiosis, (...) is the result of deep natural laws (the outlines of which we are only beginning to perceive) and reflects a degree of holism in those systems that led to life. Further, such an approach may lead to the development of a more general theory of biology and of natural organization, one informed by semiotic concepts. (shrink)

In this chapter I investigate the prospects of integrated history and philosophy of science, by examining how philosophical issues raised by “hidden entities”, entities that are not accessible to unmediated observation, can enrich the historical investigation of their careers. Conversely, I suggest that the history of those entities has important lessons to teach to the philosophy of science. Hidden entities have played a crucial role in the development of the natural sciences. Despite their centrality to past scientific practice, however, several (...) of them (e.g., phlogiston, caloric, and the ether) turned out to be fictitious. For this reason, they have figured prominently in recent debates on scientific realism. The issues I explore in this paper are entangled with those debates. I argue that our understanding of hidden entities and their role in experimental practice can be enhanced by adopting an integrated historical-cum-philosophical approach. On the one hand, philosophical reflection on the reality of those entities has a lot to gain by examining historically how they were ntroduced and investigated. On the other hand, the historical reconstruction of the careers of those entities may profit from philosophical reflection on their existence. (shrink)

There is something distinctively different about explanation in the biological sciences, as opposed to explanation in the physical sciences. In the former one has functional arguments, arguments making reference to what Aristotle called “final causes.” As in: “The function of the plates on the back of the Stegosaurus was to keep the body at a constant temperature.” Since the Scientific Revolution, such explanations have been forbidden in the physical sciences. Does this then mean that biology is second rate, as is (...) suggested by many including Immanuel Kant? It is argued that the Darwinian mechanism of natural selection explains why there is need of functional explanation in biology and that once this point is grasped, there is no reason to judge biology second rate.

My book, "The Darwinian Revolution" gives an overview of the revolution as understood at the time of its writing (1979). It shows that many factors were involved, from straight science through philosophical methodology, and on to religious influences and challenges. Also of importance were social factors, not the least of which was the professionalization of science in Britain in the 19th century. Since the appearance of that book, new, significant factors have become apparent, and here I discuss some of the (...) most important -- especially the way in which evolution as an idea came into being as an epiphenomenon of the ideology of cultural progress; the (often tense) interaction between ideas of biological progress and the urge to professionalization, and of how this led to a delay in the full appreciation of what Charles Darwin had done in the "Origin;" and the ongoing divide between biological functionalists and biological formalists, a Kuhnian-type paradigm difference that persists across the Darwinian revolution.

Francis Collins, the director of the NEH and well-known Christian, has said that agnosticism is a bit of a cop-out. Either be a Christian or be an atheism, but have the guts to make up your mind. I shall argue in a positive way for agnosticism, showing that it can be as vibrant a position as belief or non-belief. It gives you a renewed appreciation of life and the world in which we live.

Abstract Drawing upon evolutionary theory and the work of Daniel Dennett and Nicholas Agar, I offer an argument for broadening discussion of the ethics of disenhancement beyond animal welfare concerns to a consideration of animal “biopreferences”. Short of rendering animals completely unconscious or decerebrate, it is reasonable to suggest that disenhanced animals will continue to have some preferences. To the extent that these preferences can be understood as what Agar refers to as “plausible naturalizations” for familiar moral concepts like beliefs (...) and desires, then they can make moral claims on us and provide support for intuitive opposition to disenhancement.

The argument from design and Aquinas’ fifth way: In scientific literature it is common to make equivalence between the so-called argument from design and the fifth way of Thomas Aquinas. It is commonly assumed that both demonstrations for the existence of God are based on the concept of finality to proof the need for an intelligent being capable of causing order in nature. However, we think that the differences between the two arguments have great significance: each of them have as (...) starting point a different type of order, are based on a different kind of finality, and the way in which they use the principle of causality is also different. We believe that such differences permit us to say that the two arguments are not at all comparable and may even be seen as opposite arguments. (shrink)
