There has been much discussion of so-called teleosemantic approaches to the naturalization of content. Such discussion, though, has been largely confined to simple, innate mental states with contents such as ?There is a fly here.? Even assuming we can solve the issues that crop up at this stage, an account of the content of human mental states will not get too far without an account of productivity: the ability to entertain indefinitely many thoughts. The best-known teleosemantic theory, Millikan's biosemantics, offers (...) an account of productivity in thought. This paper raises a basic worry about this account: that the use of mapping functions in the theory is unacceptable from a naturalistic point of view. (shrink)

This is a short overview of the biological functions debate in philosophy. While it was fairly comprehensive when it was written, my short book ​A Critical Overview of Biological Functions has largely supplanted it as a definitive and up-to-date overview of the debate, both because the book takes into account new developments since then, and because the length of the book allowed me to go into substantially more detail about existing views.

Classifying is a fundamental operation in the acquisition of knowledge. Taxonomic theory can help students of cognition, evolutionary psychology, ethology, anatomy, and sociobiology to avoid serious mistakes, both practical and theoretical. More positively, it helps in generating hypotheses useful to a wide range of disciplines. Composite wholes, such as species and societies, are “individuals” in the logical sense, and should not be treated as if they were classes. A group of analogous features is a natural kind, but a group of (...) homologous features is not. Imposing hypotheses justified only on the basis of nominalist, realist, phenomenalist, or conceptualist metaphysics upon the neurophysiology of organisms or upon the causes of behavior exemplifies the “psychologist's fallacy” of William James. Levels should be distinguished from their members and from classes of levels, and the ontological status of entities ranked at levels should be made clear. It is important not to confuse such categories as substance and process with one another. Several genetical terms, such as “gene” and chromosome,” are even more equivocal than has been realized. Discussions about units of selection, behavior, and thinking suffer from the ambiguity of a “unit of” an entity. An important source of misunderstanding about natural selection is the habit of treating it as an “agent”: in an important sense, natural selection does not “act” at all. (shrink)

Teleological terms such as "function" and "design" appear frequently in the biological sciences. Examples of teleological claims include: A (biological) function of stotting by antelopes is to communicate to predators that they have been detected. Eagles' wings are (naturally) designed for soaring. Teleological notions were commonly associated with the pre-Darwinian view that the biological realm provides evidence of conscious design by a supernatural creator. Even after creationist viewpoints were rejected by most biologists there remained various grounds for concern about the (...) role of teleology in biology, including whether such terms are: 1. vitalistic (positing some special "life-force"); 2. requiring backwards causation (because future outcomes explain present traits); 3. incompatible with mechanistic explanation (because of 1 and 2); 4. mentalistic (attributing the action of mind where there is none); 5. empirically untestable (for all the above reasons). Opinions divide over whether Darwin's theory of evolution provides a means of eliminating teleology from biology, or whether it provides a naturalistic account of the role of teleological notions in the science. Many contemporary biologists and philosophers of biology believe that teleological notions are a distinctive and ineliminable feature of biological explanations but that it is possible to provide a naturalistic account of their role that avoids the concerns above. Terminological issues sometimes serve to obscure some widely-accepted distinctions. (shrink)

Despite their importance in the history of philosophy and in particular in the work of Aristotle and Kant, mental capacities have been neglected in recent philosophical work. By contrast, the notion of a capacity is deeply entrenched in psychology and the brain sciences. Driven by the idea that a cognitive system has the capacity it does in virtue of its internal components and their organization, it is standard to appeal to capacities in cognitive psychology. The main benefit of invoking capacities (...) in an account of the mind is that it allows for an elegant counterfactual analysis of mental states: it allows us to analyze mental states on three distinct yet interrelated levels. A first level of analysis pertains to the function of mental capacities. A second level of analysis pertains to the mental capacities employed, irrespective of the context in which they are employed. A third level of analysis pertains to the mental capacities employed, taking into account the context in which they are employed. This paper develops an account of perceptual capacities. This account involves an analysis of their function, their individuation and possession conditions, the relation between perceptual capacities and their employment, as well as their informational and neural base conditions.

Michael Ruse has offered an interesting and insightful analysis of function statements in biology. The analysis he gives of statements of the form ‘The function of x in z is to do y‘ is : z does y by using x.y is an adaptation.The first thing to notice about this formulation is the peculiarity of step. There are many cases in which we would naturally say that x was the adaptation, instead of y; or perhaps we might say that everything (...) asserted in step constituted the adaptation. For example, the function of the duck's webbed feet is to enable it to swim. But we would commonly and naturally say that the adaptation was the webbing, not the swimming. It seems to me that Ruse's insistence on the formulation in points to the major difficulty of his analysis : and understanding what drives him to this unnatural formulation suggests the way out of those difficulties.

I will discuss some of the implications of the ongoing Darwinian revolution for theology as a constructor and interpreter of human meaning. Focus will be directed toward the following issues: How should we best understand ourselves in the new, evolutionary cosmos? What are the problems with the kind of genetic reductionism espoused by neo‐Darwinism? How are those problems resolved by the “relational” understanding of life made available by thermodynamics and ecology? How do we generate meaning‐structures in this relationally‐constituted cosmos? Finally, (...) how do these developments enrich our understandings of responsibility—to each other and to our private conceptions of God? (shrink)

Can Contemporary Science Inspire Philosophical and Theological Reflection on Causality? The cooperation between natural science, philosophy, and theology in an analysis of the causal structure and co-dependency of entities in the universe seems to be both legitimate and expected. It turns out, however, that in practice it oftentimes raises some tensions, questions and difficulties, leading to the development of alternative and in a sense competitive models of causality and of God’s action in the world. What is more, the attitude of (...) natural sciences since modernity, concentrated on gaining knowledge about natural phenomena to predict and control them, without trying to determine the nature of their ultimate causes, Humean criticism and rejection of the concept of causality as such, and concentration of analytic philosophers on the description of what accompanies phenomena classified as causal, leaving aside the question of the metaphysical status of causes and effects – they all seem to make impossible an interaction and mutual reference of contemporary science, philosophy, and theology in their reflection on the topic of causation. The main goal of this article is to defend the thesis about the possible and actual influence of scientific analysis of cause and effect relationships on the philosophical and theological reflection on causation, not only in the Middle Ages and Modernity, but also in contemporary thought. The presentation of the latest positions in the debate on divine action in the natural world will be followed by an argument in favor of the relevance of the model developed by philosophers and theologians representing the Thomistic school.

Revaluation of the problem of natural teleology seems an important precondition for elucidating our environmental crisis and for formulating an 'econological ethics', because it calls for a recognition of an intrinsic value in nature and organisms. Therefore, it is necessary to show that the concept of natural teleology is not in contradiction with scientific theories, in particular not with the theory of evolution. In this paper I shall argue that there is a fundamental misunderstanding about the concepts of teleology and (...) chance in modern thinking. This as a result of a radical transformation of the Aristotelian concept of teleology by Christian theologians during the Middle Ages. This confusion resulted in the rejection of teleology from evolution and in an exaggeration of the role of chance. However, not a solution for the problem of teleology is given here, but only an attempt to prove that neither the fossil-record, nor the role of chance in evolution can give adequate arguments for the negation of teleology in evolution. That is not to say that, therefore there exists teleology in evolution, but the problem of teleology in nature cannot, be solved by the scientific theory of evolution, but only be elucidated by philosophical analysis. At the end of the paper it is argued that teleology must be rather presupposed in evolution. (shrink)

Williams argued that Darwin replaced teleology by natural selection. This article argues that this idea is based on a misunderstanding of Darwin’s critique of the argument from design. Darwin did not replace teleology by evolutionary explanations but showed that we can understand teleology without referring to a Designer. He eliminated the concept of design and rehabilitated Aristotelian teleological explanations. The implication is that adaptations should not be investigated as if designed, but with the help of both teleological and evolutionary explanations. (...) It is argued that elaborations of teleological explanations enable us to reconcile evolutionary theory and other fields in science. (shrink)

This article considers the imago Dei from the perspective of paleoanthropology. We identify structural, functional, and relational elements of the imago Dei that emerged mosaically during human evolution. Humans are unique in their ability to relate to each other and to God, and in their membership of cultural communities where shared attention, the transmission of moral norms, and symbolic behavior are important elements. We discuss similarities between our approach and the concept of theosis adopted in the Eastern Orthodox Church.

Representations are not only used in our folk-psychological explanations of behaviour, but are also fruitfully postulated, for example, in cognitive science. The mainstream view in cognitive science maintains that our mind is a representational system. This popular view requires an understanding of the nature of the entities they are postulating. Teleosemantic theories face this challenge, unpacking the normativity in the relation of representation by appealing to the teleological function of the representing state. It has been argued that, if intentionality is (...) to be explained in teleological terms, then the function of a state cannot depend on its phylogenetical history, given the metaphysical possibility of a duplicate of an intentional being that lacks an evolutionary history. In this paper, I present a method to produce, according to our current knowledge in genetic engineering, human-like individuals who are not the product of natural selection in the required sense. This variation will be used to shed light on the main replies that have been offered in the literature to the Swampman thought experiment. I argue that these replies are not satisfactory: representations should better not depend on natural selection. I conclude that a non-etiological notion of function is to be preferred for characterizing the relation of representation. (shrink)

Philosophers of biology have developed an extensive literature on biological functions. Here I propose a treatment of the topic based in social studies of science. I posit that the chief philosophical accounts of biological functions all rest upon a realist ontology of biological functions, one that conceives functions as human-independent qualities of things. Rather than being conceptualised as a property of traits or structures, function should be understood as a status granted by communities acting in accordance with specific domains of (...) knowledge and practice. Function becomes not a property of things, but a collective good: not of things, but by communities. I survey the existing explanations of biological functions from the philosophical literature and identify what I take to be those accounts’ shared complications. I then employ Martin Kusch’s communitarian epistemology as a point of departure for a sociological conception of function and develop an explanation of function that rests on an understan.. (shrink)

Plant and animal species are information-processing entities of such complexity, integration, and adaptive competence that it may be scientifically fruitful to consider them intelligent. The possibility arises from the analogy between learning and evolution, and from recent developments in evolutionary science, psychology and cognitive science. Species are now described as spatiotemporally localized individuals in an expanded hierarchy of biological entities. Intentional and cognitive abilities are now ascribed to animal, human, and artificial intelligence systems that process information adaptively, and that manifest (...) problem-solving abilities. The structural and functional similarities between such systems and species are extensive, although they “are usually obscured by population-genetic metaphors that have nonetheless contributed much to our understanding of evolution.In this target article, I use Sewall Wright's notion of the “adaptive landscape” to compare the performances of evolving species to those of intelligent organisms. With regard to their adaptive achievements and the kinds of processes by which they are achieved, biological species compare very favorably to intelligent animals by virtue of interactions between populations and their environments, between ontogeny and phylogeny, and between natural, interdemic, organic, and species selection. Addressing the question of whether species are intelligent could help to refine our ideas about species, evolution, and intelligence, and could open new lines of empirical and theoretical inquiry in many disciplines.

Recent accounts of teleological naturalism hold that organisms are intrinsically goaldirected entities. We argue that supporters and critics of this view have ignored the ways in which it is used to address quite different problems. One problem is about biology and concerns whether an organism-centered account of teleological ascriptions would improve our descriptions and explanations of biological phenomena. This is different from the philosophical problem of how naturalized teleology would affect our conception of nature, and of ourselves as natural beings. (...) The neglect of this metatheoretic distinction has made it difficult to understand the criteria we should use for evaluating proposals to naturalize teleology. We argue that a clearer distinction between scientific and philosophical contexts shows that we need more than one set of criteria for evaluating proposals to naturalize teleology, and that taking these into account might advance or dissolve recurring debates in the literature.

Nietzsche attributes 'will power' to all living things, but this seems in sharp conflict with other positions important to him-and implausible besides. The doctrine smacks of both metaphysics and anthropomorphizing, which he elsewhere derides. Will to power seems to be an intentional end-directedness, involving cognitive or representational powers he is rightly loath to attribute to all organisms, and tends to downplay even in persons. This paper argues that we find a stronger reading of will to power-both more plausible and more (...) consistent with Nietzsche's other views-by developing his affinities with Darwinism. By seeing will to power as an 'internal revision' to Darwinism, opposing the latter's stress (as Nietzsche thinks) on 'survival', but assenting to its uses of natural selection, we can ground or naturalize that notion, congenially to Nietzsche and to us.

The explanatory role of natural selection is one of the long-term debates in evolutionary biology. Nevertheless, the consensus has been slippery because conceptual confusions and the absence of a unified, formal causal model that integrates different explanatory scopes of natural selection. In this study we attempt to examine two questions: (i) What can the theory of natural selection explain? and (ii) Is there a causal or explanatory model that integrates all natural selection explananda? For the first question, we argue that (...) five explananda have been assigned to the theory of natural selection and that four of them may be actually considered explananda of natural selection. For the second question, we claim that a probabilistic conception of causality and the statistical relevance concept of explanation are both good models for understanding the explanatory role of natural selection. We review the biological and philosophical disputes about the explanatory role of natural selection and formalize some explananda in probabilistic terms using classical results from population genetics. Most of these explananda have been discussed in philosophical terms but some of them have been mixed up and confused. We analyze and set the limits of these problems. (shrink)

If “perfectionism” in ethics refers to those normative theories that treat the fulfillment or realization of human nature as central to an account of both goodness and moral obligation, in what sense is “human flourishing” a perfectionist notion? How much of what we take “human flourishing” to signify is the result of our understanding of human nature? Is the content of this concept simply read off an examination of our nature? Is there no place for diversity and individuality? Is the (...) belief that the content of such a normative concept can be determined by an appeal to human nature merely the result of epistemological naiveté? What is the exact character of the connection between human flourishing and human nature? These questions are the ultimate concern of this essay, but to appreciate the answers that will be offered it is necessary to understand what is meant by “human flourishing.” “Human flourishing” is a relatively recent term in ethics. It seems to have developed in the last two decades because the traditional translation of the Greek term eudaimonia as “happiness” failed to communicate clearly that eudaimonia was an objective good, not merely a subjective good.

In this paper we wish to raise the following question: which conceptual obstacles need to be overcome to arrive at a scientific and theoretical understanding of the mind? In the course of this examination, we shall encounter methodological and explanatory challenges and discuss them from the point of view of the philosophy of chemistry and quantum mechanics. This will eventually lead us to a discussion of emergence and metaphysics, thereby focusing on the status of objects. The question remains whether this (...) could be interpreted in terms of a re-description or dissolution of seemingly troubling problems in the philosophy of mind, or whether it further emphasizes the problematic: the ubiquitous and irreducible role of mind and consciousness in scientific activities.

This essay responds to an article, “Epistemic Grace: Antirelativism as Theology in Disguise,” by the philosopher and sociologist of knowledge David Bloor that was published in Common Knowledge 13, nos. 2–3 : 250–80. Bloor's main argument was that there is no third way between relativism and absolutism—that all philosophical positions must fall under one or the other heading. Daniel Paksi's response is that Bloor covertly subscribes to a trichotomy of umbrella headings: idealist relativism, materialist relativism, and absolutism. Bloor, it is (...) argued, connects relativism with neo-Darwinist materialism in order to differentiate his own kind of relativism from the irrealist kind, which denies scientific progress. Paksi argues as well that third ways between idealism and materialism are available—for example, the emergentism of Michael Polanyi—but his main claim is that materialism itself is an absolutist view and thus that its supposed compatibility with relativism undermines Bloor's own aims.
