“Teleosemantic” or “biosemantic” theories form a strong naturalistic programme in the philosophy of mind and language. They seek to explain the nature of mind and language by recourse to a natural history of “proper functions” as selected-for effects of language- and thought-producing mechanisms. However, they remain vague with respect to the nature of the proposed analogy between selected-for effects on the biological level and phenomena that are not strictly biological, such as reproducible linguistic and cultural forms. This essay (...) critically explores various interpretations of this analogy. It suggests that these interpretations can be explicated by contrasting adaptationist with pluralist readings of the evolutionary concept of adaptation. Among the possible interpretations of the relations between biological adaptations and their analogues in language and culture, the two most relevant are a linear, hierarchical, signalling-based model that takes its cues from the evolution of co-operation and joint intentionality and a mutualistic, pluralist model that takes its cues from mimesis and symbolism in the evolution of human communication. Arguing for the merits of the mutualistic model, the present analysis indicates a path towards an evolutionary pluralist version of biosemantics that will align with theories of cognition as being environmentally “scaffolded”. Language and other cultural forms are partly independent reproducible structures that acquire proper functions of their own while being integrated with organism-based cognitive traits in co-evolutionary fashion.

In this paper I display a general metaphysical assumption that characterizes basic naturalistic views and that is inherited, in a residual form, by their leading teleological rivals. The assumption is that intentional states require identifiable inner vehicles and that to explain intentional properties we must develop accounts that bind specific contents to specific vehicles. I show that this assumption is deeply rooted in representationalist and reductionist theories of content and I argue that it is deeply inappropriate. I sketch the main (...) features of plausible alternatives: such alternatives are either anti-representationalist (Dynamical Systems' models) or anti-reductionist (institution-based approaches), and are not committed to any such metaphysical premise.

The purpose of this book is to construct a naturalistic theory of meaning. Millikan starts with two suppositions. First, like the devices of many other biological systems, "we suppose that normally a natural-language device has continued to be proliferated only because it has served a describable, stable function or set of functions." Second, like the operative features of many other biological devices, "speaker utterances of a language device presumably are proliferated only in so far as stable overt or (...) covert reactions by cooperating partners... are also proliferated." From these naturalistic suppositions the notion of proper function is derived, refined, and applied to language devices. This provides a basis for a naturalistic explanation of intentionality as well as for the development of what Millikan calls "Fregean" sense, which she sharply distinguishes from intensionality. For Millikan we may have different "iterated programs" for recognizing for example, gold, but share the publicly construed sense of gold. Millikan then applies her theory of meaning to a number of problems in the philosophy of language including the references of indexicals, descriptions, and negations. Millikan provides further support for her theory of meaning by constructing a compatible theory of identity and a compatible epistemology. (shrink)

The desire to understand the mathematics of living systems is increasing. The widely held presupposition that the mathematics developed for modeling of physical systems as continuous functions can be extended to the discrete chemical reactions of genetic systems is viewed with skepticism. The skepticism is grounded in the issue of scientific invariance and the role of the International System of Units in representing the realities of the apodictic sciences. Various formal logics contribute to the theories of biochemistry and molecular biology (...) and genetics. Various paths of extension are invoked in these formal logics in order to express the information of biological apodicticism. Symbolizing the appropriate notations for invariant relations and for biological extensions of relations is fundamental to the exact generating functions of discrete algebraic biology. Aspects of philosophical perspectives of the relation scientific number systems are contrasted. The deep distinction between physical motion and biological motion is expressed in terms the roles of Aristotelian causes. The interior motion within perplex numbers is contrasted with the exterior motion of physical systems. The need for a new mathematics for biology is suggested. (shrink)

This is an extended review of John Dupré's _Processes of Life_, a collection of essays. It clarifies Dupré's concepts of reductionism and anti-reductionism, and critically examines his associated discussions of downward causation, and both the context sensitivity and multiple realization of categories. It reviews his naturalistic monism, and critically distinguishes between his realism about categories and constructivism about classification. Challenges to his process ontology are presented, as are arguments for his pluralism about scientific categories. None of his (...) main conclusions are rejected; rather it is main arguments for them that are the focus. (shrink)

Evidence from molecular genetics bolsters the claim that color is not a perceptuolinguistic and behavioral universal. Neurobiology continues to fill in many details about the flow of color information from photon reception to central processing in the brain. Humans have the most acute color vision in the biosphere because of natural selection and adaptation, not coincidence.

Sloan Situating Kant's philosophical project in relation to the natural sciences of his day has been of concern to several scholars from both the history of science (...) and the history of philosophy. Historians of philosophy have displayed an expanded awareness of, and interest in, the importance of the scientific context of the period in which Kant carried out his "Copernican" revolution. Most commonly among philosophers, this interest has been analyzed in relation to Kant's concerns with the foundations of mechanics, matter theory, and the epistemology of Newtonian science, with the central text of interest being the Metaphysische Anfangsgründe. On the other hand, historians of philosophy and historians of science, interested in the issues of the third Critique and in the several papers of Kant dealing with biological and anthropological issues, have emphasized the unified nature of Kant's inquiries into the natural sciences, and the importance of his continued interest in the life and human sciences alongside his interests in the foundations of the physical sciences. The effort to understand the unity of Kant's.. (shrink)

The general structure of Steels & Belpaeme's (S&B's) central premise is appealing. Theoretical stances that focus on one type of mechanism miss the fact that multiple mechanisms acting in concert can provide convergent constraints for a more robust capacity than any individual mechanism might achieve acting in isolation. However, highlighting the significance of complex constraint interactions raises the possibility that some of the relevant constraints may have been left out of S&B's own models. Although abstract modeling can help clarify issues, (...) it also runs the risk of oversimplification and misframing. A more subtle implication of the significance of interacting constraints is that it calls for a close relationship between theoretical and empirical research. (shrink)

The aim of this paper is to describe and analyze the epistemological justification of a proposal initially made by the biomathematician Robert Rosen in 1958. In this theoretical proposal, Rosen suggests using the mathematical concept of “category” and the correlative concept of “natural equivalence” in mathematical modeling applied to living beings. Our questions are the following: According to Rosen, to what extent does the mathematical notion of category give access to more “natural” formalisms in the modeling of living beings? Is (...) the so -called “naturalness” of some kinds of equivalences (which the mathematical notion of category makes it possible to generalize and to put at the forefront) analogous to the naturalness of living systems? Rosen appears to answer “yes” and to ground this transfer of the concept of “natural equivalence” in biology on such an analogy. But this hypothesis, although fertile, remains debatable. Finally, this paper makes a brief account of the later evolution of Rosen’s arguments about this topic. In particular, it sheds light on the new role played by the notion of “category” in his more recent objections to the computational models that have pervaded almost every domain of biology since the 1990s.

Adults have been shown to attribute certain properties more frequently than others to the dead. This category-specific pattern has been interpreted in terms of simulation constraints, whereby it may be harder to imagine the absence of some states than others. Afterlife beliefs have also shown context-sensitivity, suggesting that environmental exposure to different types of information might influence adults? reasoning about post-death states. We sought to clarify category and context effects in adults afterlife reasoning. Participants read a story describing the death (...) of a human protagonist after exposure to a biological prime, an emotional prime, or no prime. Emotions, desires, and epistemic states were more frequently attributed to the dead character than biological, psychobiological, and perceptual states, partially replicating previous findings. The biological prime decreased the attribution of certain post-death states relative to the control condition, whereas the emotional prime had no effect. Simulation theory does not provide a satisfactory explanation of the present findings, which may be better accounted for by conflict between different cognitive systems that are engaged in thinking about the dead.

Talk of higher categories (ranks) like Genus and Family is ubiquitous in biology. Yet there is widespread skepticism about these categories. We can locate the source of this skepticism in the lack of “robust concepts” for these categories, robust theories of what it is to be in a certain category. A common defense of category talk is that its virtues are “just pragmatic and not theoretic”. But this strains credulity. We should suppose rather that talk of the (...) higher categories does theoretical work. What work? The paper proposes a “minimal concept” for a category, according to which the category is at least explanatory in marking out, in a rough and ready way, a level in the hierarchy of explanatory taxa. The skepticism is exaggerated. (shrink)

A minimal essentialism (‘intrinsic biological essentialism’) about natural kinds is required to explain the projectability of human science terms. Human classifications that yield robust and ampliative projectable inferences refer to biological kinds. I articulate this argument with reference to an intrinsic essentialist account of HPC kinds. This account implies that human sciences (e.g., medicine, psychiatry) that aim to formulate predictive kind categories should classify biological kinds. Issues concerning psychiatric classification and pluralism are examined.

This paper addresses itself to the question as to whether Homo is properly to be considered as a political animal, or whether Homo is best understood as merely a form of social animal which has evolved particularly complex survival stratagems. We will proceed primarily on the basis of the published work of the contemporary Swiss zoologist, Adolf Portmann, and argue for the view that there are solid grounds for distinguishing between social and political animals, and that Homo inhabits the realm (...) of the political animal.

This article uses sim-max games to model perceptual categorization with the goal of answering the following question: To what degree should we expect the perceptual categories of biological actors to track properties of the world around them? I argue that an analysis of these games suggests that the relationship between real-world structure and evolved perceptual categories is mediated by successful action in the sense that organisms evolve to categorize together states of nature for which similar actions lead (...) to similar results. This conclusion indicates that both strongly realist and strongly antirealist views about perceptual categories are too simple. (shrink)

Speciesist or biological accounts of moral status can be defended by showing that all members of Homo sapiens have a moral status conferring property. In this article, I argue that the most promising defense locates the moral status conferring property in the relational property of being biologically tied to other humans. This requires that biological ties ground moral obligations. I consider and reject the best defenses of that premise. Thus, we are left with compelling evidence that biological (...) ties and membership in a biological category like “species” ground neither moral obligations nor moral status. Because it is crucial to account for the moral significance of family bonds, I conclude by describing the sense in which biological ties matter morally. (shrink)

Current controversy over whether the Office of Management and Budget system of racial and ethnic classification should be used in pharmacogenetics research as suggested by the U.S. Federal Drug Administration has been couched in terms of realist-social constructionist debates on race. The assumptions both parties to these debates share instead need to be relinquished—specifically, dichotomies between the social and scientific and what is descriptive and evaluative/normative. This paper defends a pragmatic approach to the question of the appropriateness of the OMB (...) group categories in pharmacogenetics research, an approach that is local and context-specific rather than global, incorporates practical and ethical as well as theoretical dimensions, and recognizes intersections of the social and the biological in the constitution of group categories.

Two critiques of simple adaptationism are distinguished: anti-adaptationism and extended adaptationism. Adaptationists and anti-adaptationists share the presumption that an evolutionary explanation should identify the dominant simple cause of the evolutionary outcome to be explained. A consideration of extended-adaptationist models such as coevolution, niche construction and extended phenotypes reveals the inappropriateness of this presumption in explaining the evolution of certain important kinds of features—those that play particular roles in the regulation of organic processes, especially behavior. These biological or behavioral ‘levers’ (...) are distinctively available for adaptation and exaptation by their possessors and for co-optation by other organisms. As a result they are likely to result from a distinctive and complex type of evolutionary process that conforms neither to simple adaptationist nor to anti-adaptationist styles of explanation. Many of the human features whose evolutionary explanation is most controversial belong to this category, including the female orgasm. (shrink)

Synthetic biology is a dynamic, young, ambitious, attractive, and heterogeneous scientific discipline. It is constantly developing and changing, which makes societal evaluation of this emerging new science a challenging task, prone to misunderstandings. Synthetic biology is difficult to capture, and confusion arises not only regarding which part of synthetic biology the discussion is about, but also with respect to the underlying concepts in use. This book offers a useful toolbox to approach this complex and fragmented field. It provides a (...) class='Hi'>biological access to the discussion using a 'layer' model that describes the connectivity of synthetic or semisynthetic organisms and cells to the realm of natural organisms derived by evolution. Instead of directly reviewing the field as a whole, firstly our book addresses the characteristic features of synthetic biology that are relevant to the societal discussion. Some of these features apply only to parts of synthetic biology, whereas others are relevant to synthetic biology as a whole. In the next step, these new features are evaluated with respect to the different areas of synthetic biology. Do we have the right words and categories to talk about these new features? In the third step, traditional concepts like "life" and "artificiality" are scrutinized with regard to their discriminatory power. This approach may help to differentiate the discussion on synthetic biology. Lastly our refined view is utilized for societal evaluation. We have investigated the public views and attitudes to synthetic biology. It also includes the analysis of ethical, risk and legal questions, posed by present and future practices of synthetic biology. This book contains the results of an interdisciplinary research project and presents the authors' main findings and recommendations. They are addressed to science, industry, politics and the general public interested in this upcoming field of biotechnology. (shrink)

In Kaplan and Winther’s recent article (Biol Theory. doi:10.1007/s13752-012-0048-0, 2012) they argue for three bold theses: first, that “it is illegitimate to read any ontology about ‘race’ off of biological theory or data”; second, that “using biological theory to ground race is a pernicious reification”; and, third, that “race is fundamentally a social rather than a biological category.” While Kaplan and Winther’s theses are thoughtful, I show that the arguments that their theses rest on are unconvincing. In (...) order to be constructive, I go on to show exactly how one can use biological theory and data to legitimately infer an ontological view of race, to infer a biological view of race that is not a reification, and to argue that race is both socially constructed and biologically real.

Unless one embraces activities as foundational, understanding activities in mechanisms requires an account of the means by which entities in biological mechanisms engage in their activities—an account that does not merely explain activities in terms of more basic entities and activities. Recent biological research on molecular motors exemplifies such an account, one that explains activities in terms of free energy and constraints. After describing the characteristic “stepping” activities of these molecules and mapping the stages of those steps onto (...) the stages of the motors’ hydrolytic cycles, researchers pieced together from images of the molecules in different hydrolyzation states accounts of how the chemical energy in ATP is transformed in the constrained environments of the motors into the characteristic activities of the motors. We argue that New Mechanism’s standard set of analytic categories—entities, activities, and organization—should be expanded to include constraints and energetics. Not only is such an expansion required descriptively to capture research on molecular motors but, more importantly from a philosophical point of view, it enables a non-regressive account of activities in mechanisms. In other words, this expansion enables a philosophical account of mechanistic explanation that avoids a regress of entities and activities “all the way down.” Rather, mechanistic explanation bottoms out in constraints and energetics.

Frank E. Zachos offers a comprehensive review of one of today's most important and contentious issues in biology: the species problem. After setting the stage with key background information on the topic, the book provides a brief history of species concepts from antiquity to the Modern Synthesis, followed by a discussion of the ontological status of species with a focus on the individuality thesis and potential means of reconciling it with other philosophical approaches. More than 30 different species concepts found (...) in the literature are presented in an annotated list, and the most important ones, including the Biological, Genetic, Evolutionary and different versions of the Phylogenetic Species Concept, are discussed in more detail. Specific questions addressed include the problem of asexual and prokaryotic species, intraspecific categories like subspecies and Evolutionarily Significant Units, and a potential solution to the species problem based on a hierarchical approach that distinguishes between ontological and operational species concepts. A full chapter is dedicated to the challenge of delimiting species by means of a discrete taxonomy in a continuous world of inherently fuzzy boundaries. Further, the book outlines the practical ramifications for ecology and evolutionary biology of how we define the species category, highlighting the danger of an apples and oranges problem if what we subsume under the same name ("species") is in actuality a variety of different entities. A succinct summary chapter, glossary and annotated list of references round out the coverage, making the book essential reading for all biologists looking for an accessible introduction to the historical, philosophical and practical dimensions of the species problem.

Which categories of entities qualify as ontological categories? Which combinations of categories qualify as adequate systems of ontological categories? These are the two questions the author focuses on in this article. Contrary to the usual praxis in contemporary ontological literature, he addresses both questions conjointly. First, the author presents some problems of characterizing ontological categories in purely extensional terms, i.e. as widely inclusive natural classes. Second, he introduces the transversality requirement: ontological categories should be (...) individually and naturally domain-transversal, i.e. ontological categories must be neutral concerning different scientific disciplines like physics, biology and mathematics. As a result, ontological categories must have instances in any domain of reality. Finally, the author checks the adequacy of some systems of ontological categories according to this criterion and meets some possible objections. (shrink)

The ultimate source of explanation in biology is the principle of natural selection. Natural selection means differential reproduction of genes and gene combinations. It is a mechanistic process which accounts for the existence in living organisms of end-directed structures and processes. It is argued that teleological explanations in biology are not only acceptable but indeed indispensable. There are at least three categories of biological phenomena where teleological explanations are appropriate.

This paper analyzes the notion of possibility in biology and demonstrates how synthetic biology can provide understanding on the modal dimension of biological systems. Among modal concepts, biological possibility has received surprisingly little explicit treatment in the philosophy of science. The aim of this paper is to argue for the importance of the notion of biological possibility by showing how it provides both a philosophically and biologically fruitful category as well as introducing a new practically grounded way (...) for its assessment. More precisely, we argue that synthetic biology can provide tools to scientifically anchor reasoning about biological possibilities. Two prominent strategies for this are identified and analyzed: the design of functionally new-to-nature systems and the redesign of naturally occurring systems and their parts. These approaches allow synthetic biologists to explore systems that are not normally evolutionarily accessible and draw modal inferences that extend in scope beyond their token realizations. Subsequently, these results in synthetic biology can also be relevant for discussions on evolutionary contingency, providing new methods and insight to the study of various sources of unactualized possibilities in biology.

Kant's Critique of Judgment has often been interpreted by scholars as comprising separate treatments of three uneasily connected topics: beauty, biology, and empirical knowledge. Rachel Zuckert's book interprets the Critique as a unified argument concerning all three domains. She argues that on Kant's view, human beings demonstrate a distinctive cognitive ability in appreciating beauty and understanding organic life: an ability to anticipate a whole that we do not completely understand according to preconceived categories. This ability is necessary, moreover, for (...) human beings to gain knowledge of nature in its empirical character as it is, not as we might assume it to be. Her wide-ranging and original study will be valuable for readers in all areas of Kant's philosophy. (shrink)

I formulate in relational terms the ubiquitous biological interaction of symbiosis. I explicate the topology of the different modes of relational interactions of (M, R)-networks, the entailment diagrams that model the host and the symbiont. These modes all have biological realizations as various categories of symbiotic relationships, ranging from mutualism to parasitism to infection.

This paper has two parts: In the first part, I give a general survey of the various reasons 17th and 18th century life scientists and metaphysicians endorsed the theory of pre-existence according to which God created all living beings at the creation of the universe, and no living beings are ever naturally generated anew. These reasons generally fall into three categories. The first category is theological. For example, many had the desire to account for how all humans are stained (...) by original sin (we were all there). As another example of a theological motivation, some take the organism as an obvious starting point for a teleological argument for God’s existence, and this staring point is sometimes developed into a full-blown theory of pre-existence. The second category could be thought of as non-theological metaphysical, and paramount here is the desire to deal with the metaphysical problem of individuation. So, for example, Leibniz embraces a version of hylomorphism in order to overcome difficulties with Descartes’ theory of material substance, including the difficulty of how to account for enduring material individuals, and Leibniz’s hylomorphism is closely linked with his embrace of pre-existence. The third category might be termed “biological”, and one example of such a concern is how to explain the organic unity of living beings where the whole seems to ontologically precede the parts. This is frequently translated into a temporal priority of whole to parts, and thus pre-existence is posited. Of course, many natural philosophers of the early modern period embrace pre-existence for more than one reason, but in general, these are the three classes of motivations one might have for embracing the theory. In the second part of the paper I examine in detail one argument that appears in the work of Malebranche. On the face of it, this argument seems to be a biological one, specifically the biological or organic holism argument mentioned above. But upon closer examination, I shall argue, Malebranche’s reasons for endorsing pre-existence bring together several of the arguments discussed in the first part of the paper. I conclude with some considerations about what we can learn about Malebranche as a natural philosopher from his motivations for holding the pre-existence doctrine of generation. (shrink)

A classification of models of reduction into three categories — theory reductionism, explanatory reductionism, and constitutive reductionism — is presented. It is shown that this classification helps clarify the relations between various explications of reduction that have been offered in the past, especially if a distinction is maintained between the various epistemological and ontological issues that arise. A relatively new model of explanatory reduction, one that emphasizes that reduction is the explanation of a whole in terms of its parts (...) is also presented in detail. Finally, the classification is used to clarify the debate over reductionism in molecular biology. It is argued there that while no model from the category of theory reduction might be applicable in that case, models of explanatory reduction might yet capture the structure of the relevant explanations.

We investigated the understanding of causal systems categories—categories defined by common causal structure rather than by common domain content—among college students. We asked students who were either novices or experts in the physical sciences to sort descriptions of real-world phenomena that varied in their causal structure (e.g., negative feedback vs. causal chain) and in their content domain (e.g., economics vs. biology). Our hypothesis was that there would be a shift from domain-based sorting to causal sorting with increasing expertise (...) in the relevant domains. This prediction was borne out: The novice groups sorted primarily by domain and the expert group sorted by causal category. These results suggest that science training facilitates insight about causal structures. (shrink)

Biological research on race has often been seen as motivated by or lending credence to underlying racist attitudes; in part for this reason, recently philosophers and biologists have gone through great pains to essentially deny the existence of biological human races. We argue that human races, in the biological sense of local populations adapted to particular environments, do in fact exist; such races are best understood through the common ecological concept of ecotypes. However, human ecotypic races do (...) not in general correspond with 'folk' racial categories, largely because many similar ecotypes have multiple independent origins. Consequently, while human natural races exist, they have little or nothing in common with 'folk' races. (shrink)

The biology of race has a long and contentious history, particularly in theUnited States. Thus, it should not be surprising that the use of racial and ethnic categories by some biomedical researchers over the past 20 years has occasioned heated debate among historical, sociological, anthropological, bioethical, genetic, biomedical and molecular biological circles. Differences between the genetics of populations have generated vastly more controversy than genetic differences among individuals of a particular population (Fujimura, Duster, and Rajagopalan 2008). Contemporary racial (...) categories are largely inherited from Carl von Linné (Linnaeus) and Johann Friedrich Blumenbach, both of whom were dedicated to the .. (shrink)

How do-or how should-we parse the world into kinds of things? Going back at least to Plato, most philosophers have done so with respect to some notion or other of natural kinds. And many analyses of natural kinds have been essentialistic-that is defining those kinds with respect to universals, or some set of intrinsic properties, or necessary and sufficient conditions. And there's a long-standing dispute between thinkers who regard scientific categories as natural kinds with essential properties fixed by nature-those (...) that "cut nature at its joints"-and thinkers who maintain that our classifications and categories have no essence and instead merely reflect human interests and values. A typical example of the former would be "having a mass of 1.7 × 10-27," and examples of the latter would be the categories of "ADHD," "race," or "child abuse." Khalidi aims for an epistemic, naturalistic, non-essentialist, account of natural kinds, one which comfortably embraces not only the usual candidates favored by essentialists (e.g., elementary particles, chemical elements, biological species), but also categories in the social and behavioral sciences. Drawing on cases from many scientific fields, from fluid mechanics and polymer science to virology and psychiatry, Khalidi argues that "natural kinds are investigative or epistemic kinds, in the sense that they are the categories revealed by our systematic attempts to gain knowledge of nature" (p. 43). Moreover, he claims that natural kinds can be "fuzzy" (i.e. have indefinite boundaries), satisfy epistemic virtues to varying degrees, and be mind-dependent in a way that doesn't detract from their reality or objectivity. Although the book is pitched for a sophisticated and philosophically informed audience (and, needless to say, too complex to be adequately summarized in a brief notice such as this), it's clearly written, nuanced, compellingly argued, and worth the effort for JSE readers curious about the unavoidable metaphysical dimensions of doing science of any kind.
