This essay discusses Elliott Sober’s Evidence and Evolution: The Logic Behind the Science. Valuable to both philosophers and biologists, Sober analyzes the testing of different kinds of evolutionary hypotheses about natural selection or phylogenetic history, including a thorough critique of intelligent design. Not at least because of a discussion of different schools of hypothesis testing (Bayesianism, likelihoodism, and frequentism), with Sober favoring a pluralism where different inference methods are appropriate in different empirical contexts, the book has lessons for philosophy of (...) science beyond its evolutionary focus. I criticize Sober for not including epistemic values and social aspects of scientific practice in his epistemological framework. (shrink)

In this paper, we defend a representational approach to at least some kinds of non-human psychopathology. Mentally-ill non-human minds, in particular in delusions, obsessive-compulsive disorders and similar cognitive states, are traditionally understood in purely behavioral terms. In contrast, we argue that non-human mental psychopathology should be at least sometimes not only ascribed contentful mental representation but also understood as really having these states. To defend this view, we appeal to the interactivist account of mental representation, which is a kind of (...) a constructive approach to meaning. We follow Mark Bickhard in assuming that only an organism – either human or non-human – capable of detecting its own misrepresentations is representational. However, under his autonomy-based account of biological function these minds are incapable of misrepresentations because these minds are, ex hypothesi, unable to detect error in such representations. To solve this problem, we argue that adding a historical dimension – as in Millikan’s view on mental representations – to Bickhard’s account of function makes mental misrepresentation of mentally-ill minds possible. Using Bickhard’s dynamic account of function, it is possible to explain why delusions and other mental disorders can be seen as locally functional. However, an etiological dimension can further explain why misrepresentations seem to be globally dysfunctional. Even if representational or biosemiotic hypotheses about non-human psychopathology are difficult to confirm empirically, we defend the view that they can enrich our understanding of the causes and development of such pathologies, and may constitute a new progressive research programme.

In their 2010 book, Biology’s First Law, D. McShea and R. Brandon present a principle that they call ‘‘ZFEL,’’ the zero force evolutionary law. ZFEL says (roughly) that when there are no evolutionary forces acting on a population, the population’s complexity (i.e., how diverse its member organisms are) will increase. Here we develop criticisms of ZFEL and describe a different law of evolution; it says that diversity and complexity do not change when there are no evolutionary causes.

If selection at the group level is to be considered more than a mere possibility, it is important to find phenomena that are best explained at this level of selection. I argue that human religious phenomena provide evidence for the selection of a “pious gene” at the group level, which results in a human tendency to believe in a transcendental reality that encourages behavioral conformity to collective as opposed to individual interest.

It's been 41 years since the publication of Ernst Mayr's Cause and Effect in Biology wherein Mayr most clearly develops his version of the influential distinction between ultimate and proximate causes in biology. In critically assessing Mayr's essay I uncover false statements and red-herrings about biological explanation. Nevertheless, I argue to uphold an analogue of the ultimate/proximate distinction as it refers to two different kinds of explanations, one dynamical the other statistical.

This paper defends the position that the supposed gap between biological altruism and psychological altruism is not nearly as wide as some scholars (e.g., Elliott Sober) insist. Crucial to this defense is the use of James Mark Baldwin's concepts of “organic selection”and “social heredity” to assist in revealing that the gap between biological and psychological altruism is more of a small lacuna. Specifically, this paper argues that ontogenetic behavioral adjustments, which are crucial to individual survival and reproduction, are also crucial (...) to species survival. In particular, it is argued that human psychological altruism is produced and maintained by various sorts of mimicry and self-reflection in the aid of both individual and species survival. The upshot of this analysis is that it is possible to offer an account of psychological altruism that is closelytethered to biological altruism without reducing entirely the former to thelatter.

The dual process theory is a view that there are two information-processing systems in our mind. It has been popular in cognitive and social psychology for the last few decades, but this simplified formulation of the theory has problems. In this paper I shall review the recent developments made by the dual process theorists to meet those challenges and indicate the directions the theory could take. In particular I shall discuss possible defining properties or mechanisms of the two systems. I (...) argue that working memory and its neural correlates, but not cognitive decoupling, are the underlying mechanisms of the "reflective" system while the "intuitive" system may have rather external underlying mechanisms, i.e., natural selection. This renders both systems homeostatic property cluster kinds but they are based on different kinds of mechanisms. (shrink)

One controversy about the existence of so called evolutionary forces such as natural selection and random genetic drift concerns the sense in which such “forces” can be said to interact. In this paper I explain how natural selection and random drift can interact. In particular, I show how population-level probabilities can be derived from individual-level probabilities, and explain the sense in which natural selection and drift are embodied in these population-level probabilities. I argue that whatever causal character the individual-level probabilities (...) have is then shared by the population-level probabilities, and that natural selection and random drift then have that same causal character. Moreover, natural selection and drift can then be viewed as two aspects of probability distributions over frequencies in populations of organisms. My characterization of population-level probabilities is largely neutral about what interpretation of probability is required, allowing my approach to support various positions on biological probabilities, including those which give biological probabilities one or another sort of causal character. ‡This paper has benefited from feedback on and discussions of this and earlier work.

Recent debate on the nature of probabilities in evolutionary biology has focused largely on the propensity interpretation of fitness (PIF), which defines fitness in terms of a conception of probability known as “propensity”. However, proponents of this conception of fitness have misconceived the role of probability in the constitution of fitness. First, discussions of probability and fitness have almost always focused on organism effect probability, the probability that an organism and its environment cause effects. I argue that much of the (...) probability relevant to fitness must be organism circumstance probability, the probability that an organism encounters particular, detailed circumstances within an environment, circumstances which are not the organism’s effects. Second, I argue in favor of the view that organism effect propensities either don’t exist or are not part of the basis of fitness, because they usually have values close to 0 or 1. More generally, I try to show that it is possible to develop a clearer conception of the role of probability in biological processes than earlier discussions have allowed. (shrink)

A brief introduction to the life and work of William Paley, including a discussion of the structure of his famous design argument.

n this article the author develops a critique of reductionism in biological sciences from three different points of view. The first is related to the problem of reduction in the context of scientific theories. More specifically, reduction deals with a special form of intertheoretic relationship between molecular biology and the rest of biology. The second meaning of reductionism has to do with the significance of its genetic outfit for the ontogeny of an organism, i.e. its development from zygote to its (...) final or adult structure and function. Third, closely related to this more biological topic are questions about the anthropological consequences of the application of reductionistic methodologies for the explanation and evaluation of human behaviour.

Biological research has the capacity to inform ethical discussions. There are numerous questions about the nature of sexual orientation, intelligence, gender identity, etc., and many of these questions are commonly approached with the benefit of implicit or explicit biological commitments. The answers to these sorts of questions can have a powerful impact on social, ethical, and political positions. In this project I examine the prospect of naturalizing ethics under the umbrella of developmental systems theory (DST). If one is committed to (...) DST, then those ideas involved in DST that steer biological research will also have implications for ethics. There has been much debate over whether certain human traits or attributes are the consequence of nature or nurture. This kind of question tends to be articulated in dichotomous terms where the focal point of the discussion is over which opposing causal mechanism asserts the most power over the development of these attributes. The debate places particular importance on such distinctions as that between gene and environment, and biology and culture. DST seeks to dismiss such dichotomous accounts. In this sense, DST is an attempt to do biology without these dichotomies. In the process, DST articulates a reconceptualized notion of "the natural." I am interested in how DST’s reconceptualization of the natural can inform a naturalistic approach to ethics. Thus, the aim of this project is to examine the ramifications of taking DST as a guiding principle in the naturalization of ethics. (shrink)

Ich rekonstruiere und kritisiere Hans Drieschs Argumentation für die Behauptung, daß biologischen Prozessen nur eine substanzdualistische Ontologie der belebten Materie (Vitalismus) gerecht werden kann. Meine Diagnose lautet, daß Drieschs Argumentation zwar logisch schlüssig ist bzw. durch leichte Modifikationen in eine logisch gültige Form gebracht werden kann, aber von empirisch unbegründeten, metaphysischen Prämissen über die Möglichkeiten eines energieumwandelnden Mechanismus ausgeht.

Kann die Entstehung neuer Ideen im Menschen und die daran anschließende Verbreitung dieser neuen Ideen durch die Anwendung eines Darwinistischen Evolutionsschemas erklärt werden? Der Prozess der Kreativität und der Veränderung wäre damit genauso wie die biologische Evolution im Sinne Darwins als ein sich ständig wiederholender, graduell kumulierender Prozess von Versuch und Irrtum zu verstehen. – Ist eine solche Erklärung möglich und könnte sie im Sinne einer allgemeinen Evolutionstheorie die Kluft zwischen Geistes-und Naturwissenschaften überbrücken helfen? Diese Fragen sollen Gegenstand einer systematischen, (...) philosophischen Analyse sein. (shrink)

Causal selection is the task of picking out, from a field of known causally relevant factors, some factors as elements of an explanation. The Causal Parity Thesis in the philosophy of biology challenges the usual ways of making such selections among different causes operating in a developing organism. The main target of this thesis is usually gene centrism, the doctrine that genes play some special role in ontogeny, which is often described in terms of information-bearing or programming. This paper is (...) concerned with the attempt of confronting the challenge coming from the Causal Parity Thesis by offering principles of causal selection that are spelled out in terms of an explicit philosophical account of causation, namely an interventionist account. I show that two such accounts that have been developed, although they contain important insights about causation in biology, nonetheless fail to provide an adequate reply to the Causal Parity challenge: Ken Waters's account of actual-difference making and Jim Woodward's account of causal specificity. A combination of the two also doesn't do the trick, nor does Laura Franklin-Hall's account of explanation (in this volume). We need additional conceptual resources. I argue that the resources we need consist in a special class of counterfactual conditionals, namely counterfactuals the antecedents of which describe biologically normal interventions. (shrink)

This work consists of two parts. Part I will be a contribution to a philo- sophical discussion of the nature of causal explanation. It will present my contrastive counterfactual theory of causal explanation and show how it can be used to deal with a number of problems facing theories of causal explanation. Part II is a contribution to a discussion of the na- ture of interest explanation in social studies of science. The aim is to help to resolve some controversies (...) concerning interest explanation by explicating the concept of interest and its explanatory uses by using the account of explanation developed in Part I.

This article argues that various deviations from the basic principles of the scientific ethos – primarily the appearance of pseudoscience in scientific communities – can be formulated and explained using specific models of game theory, such as the prisoner’s dilemma and the iterated prisoner’s dilemma. The article indirectly tackles the deontology of scientific work as well, in which it is assumed that there is no room for moral skepticism, let alone moral anti-realism, in the ethics of scientific communities. Namely, on (...) the basis of the generally accepted dictum of scientific endeavor as the pursuit of knowledge exclusively for knowledge’s sake, scientifically »right« behavior is seen to be clearly defined and distinguishable from scientifically »wrong« behavior. After elucidating the basic principles of game theory, the article illustrates – by using imaginary and real cases, as well as some views from the philosophyof biology (the units of selection debate) – how this sort of reasoning could be applied in an analysis of the functioning of science.

This Ph.D. thesis provides a pilosophical account of the structure of the evolutionary synthesis of the 1930s and 40s. The first, more historical part analyses how classical genetics came to be integrated into evolutionary thinking, highlighting in particular the importance of chromosomal mapping of Drosophila strains collected in the wild by Dobzansky, but also the work of Goldschmidt, Sumners, Timofeeff-Ressovsky and others. The second, more philosophical part attempts to answer the question wherein the unity of the synthesis consisted. I argue (...) that it exemplifies a weak of form of explanatory unification.

The ecologist today finds scarce ground safe from controversy. Decisions must be made about what combination of data, goals, methods, and theories offers them the foundations and tools they need to construct and defend their research. When push comes to shove, ecologists often turn to philosophy to justify why it is their approach that is scientific. Karl Popper’s image of science as bold conjectures and heroic refutations is routinely enlisted to justify testing hypotheses over merely confirming them. One of the (...) most controversial theories in contemporary science is the Neutral Theory of Ecology. Its chief developer and proponent, Stephen Hubbell, presents the neutral theory as a bold conjecture that has so far escaped refutation. Critics of the neutral theory claim that it already stands refuted, despite what the dogmatic neutralists say. We see the controversy through a Popperian lens. But Popper’s is an impoverished philosophy of science that distorts contemporary ecology. -/- The controversy surrounding the neutral theory actually rests on a methodological fault. There is a strong but messy historical link between the concepts of being neutral and being null in biology, and Hubbell perpetuates this when he claims that the neutral theory is supplies the appropriate null for testing alternative theories. What method is being followed here? There are three contenders: -/- Null hypothesis testing tests for whether a there is a pattern to be explained. Null modeling tests for whether a process is causally relevant to a pattern. Baseline modeling apportions relative responsibility to multiple processes each relevant to a pattern. -/- Whether the neutral theory supplies an appropriate “null” depends upon whether null hypothesis, null modeling, or baseline model is intended. These methods prescribe distinct inference patterns. If they are null hypothesis testing or null modeling, the neutralists’s reasoning is invalid. If they are baseline modeling, the justification of a crucial assumption remains opaque. Either way, the neutral-null connection is being exploited rhetorically to privilege the neutral theory over its rivals. Clarifying the reasoning immunizes us against the rhetoric and foregrounds the underlying virtues of the neutralist approach to ecology. -/- The Popperian lens distorts theoretical development as dogmatism. Lakatos’s view of science as the development of research programmes clarifies the epistemology of the neutral theory. Focusing philosophical attention on the neutralist research programme illuminates (1) the synchronic uses of the neutral theory to make predictions and give descriptions and explanations; (2) its diachronic development in response to theoretical innovation and confrontation with data; (3) its complex relationships to alternative theories. For example, baseline modeling is now seen to be its primary explanatory heuristic. The justification for baseline modeling with the neutral theory, previously hidden from view, is seen in the logic of in the neutralist research programme. (shrink)

Neste trabalho, avaliamos as implicações que o debate filosófico acerca das explicações em termos de função e objetivo podem ter no contexto educacional, particularmente no ensino e aprendizagem de biologia. Para alcançar este objetivo, investigamos como três obras didáticas de biologia do Brasil utilizam a linguagem teleológica na formulação de explicações para os assuntos que são objeto de estudo dessa ciência. Na análise das obras, exploramos os enunciados teleológicos e funcionais a partir de dois projetos explanatórios discutidos na filosofia da (...) biologia contemporânea, a saber: (i) etiológico, que fornece uma abordagem essencialmente histórica de explicação biológica; e (ii) organizacional, que orienta o estudo acerca das capacidades de sistemas complexos mediante o apelo às funções de seus componentes, ou seja, a contribuição das partes para a realização de uma capacidade global. Nossos resultados mostram que poucas explicações podem ser qualificadas como etiológicas, em razão de que os autores preterem a discussão de temas segundo um tratamento evolutivo. Associado a esse resultado, a maioria dos enunciados foi localizada no contexto do projeto organizacional de explicação científica. Na análise das explicações, destacamos os principais problemas que elas apresentam, como a falta de clareza na identificação do explanandum e explanans, situação que pode prejudicar a compreensão dos assuntos pelos estudantes. Por fim, colocamos que a recontextualização das duas abordagens centrais sobre as explicações funcionais na filosofia da biologia, a perspectiva etiológica e a organizacional, podem fornecer um embasamento epistemológico consistente para as explicações biológicas no ensino médio.

This dissertation starts with a concise overview of what philosophers of science have written about unification and its role in scientific explanation during the last 50 years to provide the reader with some background knowledge. In order to bring unification back into the picture, I have followed two strategies, resulting respectively in Parts I and II of this dissertation. In Part I the idea of unification is used to refine and enrich the dominant causalmechanist and causal-interventionist accounts of scientific explanation. (...) In this part of the dissertation I bracket the classical ideas about unification: deduction and derivation. I do grant, for the sake of argument, that explanations are causal and argue that unification is important from within this causalist perspective. In Part II I continue my strategy of digging into scientific practice to find cases of ontological unification. But here I distance myself from the dominant literature that all explanations must be causal. I will investigate whether explanatory unification is possible in non-causal explanations. Part III contains some further reflections and conclusions. I will formulate my primary results, and I will elaborate on their implications for thinking about unification and explanation. The different forms of ontological unification were quite diverse. This relates to the method I have used. Throughout this dissertation the types of unification that were discussed emerged from digging into scientific practice. This philosophy-of-science-practice approach steered me towards a pluralistic view on unification and on explanation. In this dissertation I do not try to develop a new model of explanation and compare it to existing models. The aim is to show that there are important types of explanatory practice which cannot be properly analyzed if we neglect unification as a desideratum for explanations. (shrink)

Proturječnost stavova o položaju biologije unutar ili izvan područja znanosti može se podijeliti na nekoliko osnovnih pristupa. Prvi pristup smješta biologiju izvan znanstvenog područja zbog nedostatka univerzalnosti, nedostatka strogih generalizacija i nedostatka stroge kvantitativne strukture. Drugi pristup smatra biologiju znanošću koju treba svesti na fiziku. Treći pristup vidi značajne razlike između biologije s jedne, i fizike i kemije s druge strane, ali ipak tvrdi da je biologija prava znanost, no samostalna i s vlastitim pojmovnikom i metodologijom. Poredba načela prirodne znanosti (...) s obilježjima biologije ukazuje na nedostatak determinizma, neprikladnost esencijalizma i manjkavosti redukcionističkog pristupa u području biološkog. S druge strane, biologija ima neka posebna obilježja. Biologija je znanost samostalna u određenju svoga područja i biranju prikladnog pojmovnika i metoda proučavanja. Njezino područje, pojmovnik, logika i metodologija ne podudaraju se potpuno s onima ostalih znanosti, ali se u potpunosti ni ne razilaze.Ambiguities of attitudes on the position of biology within or outside of science domain can be divided into few basic approaches. The first approach places biology outside the scientific domain due to its lack of universality, the lack of strong generalizations and the lack of strong quantitative structure. The second approach claims that science of biology should be reduced to physics. The third approach accepts significant differences between biology on one side, and physics and chemistry on the other side, but it still claims that biology is a hard science, autonomous and with its own terminology and methodology. Comparison of principles of natural science with features of biology demonstrates a lack of determinism, inappropriateness of essentialism and pitfalls of reductionist approach in biological sphere. On the other hand, biology has some specific features. Biology is a science that has autonomy in determining its domain and choice of appropriate terminology and inquiry methods. Its domain, terminology, logic and methodology are not entirely in accordance with other sciences, but also are not completely diverse. (shrink)

In my dissertation I define historical disciplines as disciplines that aim to give a historical interpretation of the evidence. Phylogenetic systematics is a historical discipline and therefore in my definition phylogenies should be thought of as historical interpretations of relationships between taxa.

The dissertation criticizes two analogical applications of Darwinism to the spheres of mind and culture: the Darwinian approach to creativity and memetics. These theories rely on three basic analogies: the ontological analogy states that the basic ontological units of culture are so-called memes, which are replicators like genes; the origination analogy states that novelty in human creativity emerges in a "blind" Darwinian manner; and the explanatory units of selection analogy states that memes are "egoistic" and that they can spread independently (...) of our mind. The detailed philosophical analysis offered in the dissertation shows that these three analogies rely on either wrong or trivial statements: they provide either wrong or no new descriptions or explanations of the phenomena at hand. In Chapter One, I introduce the diverse ways, in which contemporary Darwinism is used today outside of evolutionary biology. Chapter Two explains what it means to claim that something evolves in a Darwinian manner. Chapter Three to Five address each of the three analogies separately. Darwinism applied to culture and mind, at least in the way discussed in this study, is not a dangerous idea. It leads either to wrong claims or to a re-telling in Darwinian terms of what we have already known. (shrink)

This paper explores the nature of emotions by considering what appear to be two differing, perhaps even conflicting, approaches to affectivity—an evolutionary functional account, on the one hand, and a phenomenological view, on the other. The paper argues for the centrality of the notion of function in both approaches, articulates key differences between them, and attempts to understand how such differences can be overcome.

This paper sketches a causal account of scientific explanation designed to sustain the judgment that high-level, detail-sparse explanations—particularly those offered in biology—can be at least as explanatorily valuable as lower-level counterparts. The motivating idea is that complete explanations maximize causal economy: they cite those aspects of an event’s causal run-up that offer the biggest-bang-for-your-buck, by costing less (in virtue of being abstract) and delivering more (in virtue making the event stable or robust).

In From Instrumentalism to Constructive Realism Theo Kuipers presents a theory of qualitative confirmation that is supposed to not assume the existence of quantitative probabilities. He claims that this theory is able to resolve some paradoxes in confirmation theory, including the ravens paradox. This paper shows that there are flaws in Kuipers' qualitative confirmation theory and in his application of it to the ravens paradox.

Eudaemonism is the common structure of the family of theories in which the central moral conception is eudaemonia , understood as "living well" or "having a good life." In its best form, the virtues are understood as constitutive and therefore essential means to achieving or having such a life. What I seek to do is to lay the groundwork for an approach to eudaemonism grounded in practical reason, and especially in instrumental reasoning, rather than in natural teleology. In the first (...) chapter, I argue that an approach based in natural teleology will not work. In the second, the claims of decision theory to be an adequate formal representation of instrumental reasoning are examined and found wanting. In the third, I develop an account of ordinary instrumental reasoning. In the fourth, I discuss the structure of eudaemonism, with the aim of showing that there is an intelligible and attractive doctrine that can be disentangled from the natural teleology. In the fifth, I sketch an argument showing that instrumental reasoning, as explicated in the third chapter, can bear on the selection of final and ultimate ends, and that it is plausible that the instrumental approach to moral theory that I am urging yields conclusions with a eudaemonistic structure. I also indicate directions for further development and exploration. (shrink)

This is a review of Toby Handfield's book, "A Philosophical Guide to Chance", that discusses Handfield's Debunking Argument against realist accounts of chance.

Hempel, Popper, and Kuhn argue that to be scientific is to be testable, to be falsifiable, and most nearly to do normal science, respectively. I argue that to be scientific is largely to be interactive, offering some examples from science to show that the ideas from different fields of science interact with one another. The results of the interactions are that hypotheses become more plausible, new phenomena are explained and predicted, we understand phenomena from a new perspective, and our worldview (...) becomes simpler. I also argue that given that the interactions are impressive features of science, astrology and religion would be regarded as science, provided that there are similar interactions in those enterprises.
