John Searle began to discuss his recently published book `The Construction of Social Reality' with Anthony Freeman, and they ended up talking about God. The book itself and part of their conversation are introduced and briefly reflected upon by Anthony Freeman. Many familiar social facts -- like money and marriage and monarchy -- are only facts by human agreement. They exist only because we believe them to exist. That is the thesis, at once startling yet obvious, that philosopher John Searle (...) explores in The Construction of Social Reality. (shrink)

This paper gives an account of evolutionary explanations in biology. Briefly, the explanations I am primarily concerned with are explanations of adaptations. These explanations are contrasted with other nonteleological evolutionary explanations. The distinction is made by distinguishing the different kinds of questions these different explanations serve to answer. The sense in which explanations of adaptations are teleological is spelled out.

This book is a critical survey of and guidebook to the literature on biological functions. It ties in with current debates and developments, and at the same time, it looks back on the state of discourse in naturalized teleology prior to the 1970s. It also presents three significant new proposals. First, it describes the generalized selected effects theory, which is one version of the selected effects theory, maintaining that the function of a trait consists in the activity that led to (...) its differential persistence or reproduction in a population, and not merely its differential reproduction. Secondly, it advances “within-discipline pluralism” (as opposed to between-discipline pluralism) a new form of function pluralism, which emphasizes the coexistence of function concepts within diverse biological sub-disciplines. Lastly, it provides a critical assessment of recent alternatives to the selected effects theory of function, namely, the weak etiological theory and the systems-theoretic theory. The book argues that, to the extent that functions purport to offer causal explanations for the existence of a trait, there are no viable alternatives to the selected effects view. -/- The debate about biological functions is still as relevant and important to biology and philosophy as it ever was. Recent controversies surrounding the ENCODE Project Consortium in genetics, the nature of psychiatric classification, and the value of ecological restoration, all point to the continuing relevance to biology of philosophical discussion about the nature of functions. In philosophy, ongoing debates about the nature of biological information, intentionality, health and disease, mechanism, and even biological trait classification, are closely related to debates about biological functions.

Is life different from the non-living? If so, how? And how, in that case, does biology as the study of living things differ from other sciences? These questions are traced through an exploration of episodes in the history of biology and philosophy. The book begins with Aristotle, then moves on to Descartes, comparing his position with that of Harvey. In the eighteenth century the authors consider Buffon and Kant. In the nineteenth century the authors examine the Cuvier-Geoffroy debate, pre-Darwinian geology (...) and natural theology, Darwin and the transition from Darwin to the revival of Mendelism. Two chapters deal with the evolutionary synthesis and such questions as the species problem, the reducibility or otherwise of biology to physics and chemistry, and the problem of biological explanation in terms of function and teleology. The final chapters reflect on the implications of the philosophy of biology for philosophy of science in general. (shrink)

The function of a trait token is usually defined in terms of some properties of other (past, present, future) tokens of the same trait type. I argue that this strategy is problematic, as trait types are (at least partly) individuated by their functional properties, which would lead to circularity. In order to avoid this problem, I suggest a way to define the function of a trait token in terms of the properties of the very same trait token. To able to (...) allow for the possibility of malfunctioning, some of these properties need to be modal ones: a function of a trait is to do F just in case its doing F would contribute to the inclusive fitness of the organism whose trait it is. Function attributions have modal force. Finally, I explore whether and how this theory of biological function could be modified to cover artifact function. (shrink)

What is the relation between a reason and an action when the reason explains the action by giving the agent's reason for doing what he did? We may call such explanations rationalizations, and say that the reason rationalizes the action. In this paper I want to defend the ancient - and common-sense - position that rationalization is a species of ordinary causal explanation. The defense no doubt requires some redeployment, but not more or less complete abandonment of the position, as (...) urged by many recent writers. (shrink)

Function theorists routinely speculate that a viable function theory will be equally applicable to biological traits and artifacts. However, artifact function has received only the most cursory scrutiny in its own right. Closer scrutiny reveals that only a pluralist theory comprising two distinct notions of function--proper function and system function--will serve as an adequate general theory. The first section describes these two notions of function. The second section shows why both notions are necessary, by showing that attempts to do away (...) with one of them fail. This demonstration draws on examples from the artifactual realm to motivate major points of the argument. The third section is an outline of artifact function. It confirms the conclusions of the second section, and also begins the task of describing some of the special features of artifact function needing accommodation within the general theory. (shrink)

In this paper we consider the emerging position in metaphysics that artifact functions characterize real kinds of artifacts. We analyze how it can circumvent an objection by David Wiggins (Sameness and substance renewed, 2001, 87) and then argue that this position, in comparison to expert judgments, amounts to an interesting fine-grained metaphysics: taking artifact functions as (part of the) essences of artifacts leads to distinctions between principles of activity of artifacts that experts in technology have not yet made. We show, (...) moreover, that our argument holds not only in the artifactual realm but also in biology: taking biological functions as (part of the) essences of organs leads to distinctions between principles of activity of organs that biological experts have not yet made. We run our argument on the basis of analyses of artifact and biological functions as developed in philosophy of technology and of biology, thus importing results obtained outside of metaphysics into the debate on ontological realism. In return, our argument shows that a position in metaphysics provides experts reason for trying to detect differences between principles of activities of artifacts and organs that have not been detected so far.

This 2001 book offers an examination of functional explanation as it is used in biology and the social sciences, and focuses on the kinds of philosophical presuppositions that such explanations carry with them. It tackles such questions as: why are some things explained functionally while others are not? What do the functional explanations tell us about how these objects are conceptualized? What do we commit ourselves to when we give and take functional explanations in the life sciences and the social (...) sciences? McLaughlin gives a critical review of the debate on functional explanation in the philosophy of science. He discusses the history of the philosophical question of teleology, and provides a comprehensive review of the post-war literature on functional explanation. What Functions Explain provides a sophisticated and detailed Aristotelian analysis of our concept of natural functions, and offers a positive contribution to the ongoing debate on the topic.

The view of teleology sketched in the above remarks seems to me to offer a piece of candy to both the critics and guardians of teleology. The critics want to defend against a number of things: the importation of unverifiable theological or metaphysical doctrines into the sciences; the idea that goals somehow act in favor of their won realization; and the view that biological systems require for their study concepts and patterns of explanation unlike anything employed in the physical sciences. (...) An important part of their defense has been the contention that teleological language can be eliminated without loss from the sciences. I have argued that this is true: any phenomenon that can be described in teleological language can be described otherwise.On the other hand, eliminability does not mean translatability. I have suggested—I do not see how to prove it—that the teleological character of a sentence is so fundamental that it would be preserved under translation. Teleological character is conferred on a sentence by the manner in which it fits into a conceptual scheme designed for the description of certain classes of systems possessing net-like organization. The elimination of teleological language thus involves a conceptual shift, and involves a different method of classifying the elements of a system.The guardians of teleology—myself among them—have insisted that teleological language is perfectly legitimate. This conclusion is plain if my account of “appropriateness” is correct. Indeed, the development of conceptual schemes which render functional ascriptions appropriate is seen to be just a special case of a general scientific procedure: the designing of languages aimed at bringing to light those causal relations which are most interesting to us.

The notion that natural selection is a process of fitness maximization gets a bad press in population genetics, yet in other areas of biology the view that organisms behave as if attempting to maximize their fitness remains widespread. Here I critically appraise the prospects for reconciliation. I first distinguish four varieties of fitness maximization. I then examine two recent developments that may appear to vindicate at least one of these varieties. The first is the ‘new’ interpretation of Fisher's fundamental theorem (...) of natural selection, on which the theorem is exactly true for any evolving population that satisfies some minimal assumptions. The second is the Formal Darwinism project, which forges links between gene frequency change and optimal strategy choice. In both cases, I argue that the results fail to establish a biologically significant maximization principle. I conclude that it may be a mistake to look for universal maximization principles justified by theory alone. A more promising approach may be to find maximization principles that apply conditionally and to show that the conditions were satisfied in the evolution of particular traits. (shrink)

Combining ideas from philosophy, artificial intelligence, and neurobiology, Daniel Dennett leads the reader on a fascinating journey of inquiry, exploring such intriguing possibilities as: Can any of us really know what is going on in someone else's mind? What distinguishes the human mind from the minds of animals, especially those capable of complex behavior? If such animals, for instance, were magically given the power of language, would their communities evolve an intelligence as subtly discriminating as ours? Will robots, once they (...) have been endowed with sensory systems like those that provide us with experience, ever exhibit the particular traits long thought to distinguish the human mind, including the ability to think about thinking? Dennett addresses these questions from an evolutionary perspective. Beginning with the macromolecules of DNA and RNA, the author shows how, step-by-step, animal life moved from the simple ability to respond to frequently recurring environmental conditions to much more powerful ways of beating the odds, ways of using patterns of past experience to predict the future in never-before-encountered situations. Whether talking about robots whose video-camera ”eyes” give us the powerful illusion that ”there is somebody in there” or asking us to consider whether spiders are just tiny robots mindlessly spinning their webs of elegant design, Dennett is a master at finding and posing questions sure to stimulate and even disturb.

Le présent tome traite de la mécanique quantique non relativiste. Il comprend, outre ses fondements, de multiples applications de la mécanique quantique dans une plus large mesure que dans les cours généraux. Dans leur exposé des questions générales, les auteurs dégagent au maximum l'essence physique de la théorie, à partir de laquelle ils développent l'appareil mathématique. Contrairement au schéma habituel allant des théorèmes mathématiques relatifs aux opérateurs linéaires, les auteurs déduisent les exigences mathématiques auxquelles doivent répondre les opérateurs et les (...) fonctions propres à partir de la position physique du problème. Des compléments mathématiques sont donnés en appendice. (shrink)

Transcending the various formal concepts of life, this captivating book offers a unique overview of life's history, essences, and future. "A masterpiece of scientific writing.

L'épistémologie, discipline philosophique qui scrute la connaissance scientifique des points de vue logique et méthodologique, a connu un essor considérable au cours du XXe siècle. Un bilan s'impose donc. Dans cette perspective, ce Vocabulaire répertorie près de trois mille termes clés et expressions techniques utilisés par les philosophes lorsqu'ils procèdent aujourd'hui à l'examen critique des sciences, qu'il s'agisse de sciences naturelles, formelles, humaines ou sociales. Notre propos a été d'analyser systématiquement, suivant une stricte approche lexicographique, tous les concepts importants de (...) ce domaine. En nous fondant sur un corpus composé de plusieurs centaines d'ouvrages et d'articles de revue parmi les plus marquants, notre ambition a été de fournir une description rigoureuse de l'espace notionnel de l'épistémologie contemporaine. Ainsi, toutes les publications majeures de langue française et anglaise, de Pierre Duhem à Bas Van Fraassen, ont été compulsées. Et lorsque la chose paraissait utile, nous avons recensé les diverses modulations des concepts examinés. La fréquentation assidue de ce Vocabulaire devrait permettre à toutes les personnes intéressées par l'analyse logique des sciences et par la réflexion méthodologique sur les discours à prétention scientifique d'asseoir leur compétence en matière d'épistémologie.

The book Fundamentals of Life is a bold attempt at gathering all basic knowledge of Humanity regarding the 'Mother of all questions': the essence and origin of life. The Editors are aided by first-class prominence in realising these high-set goals, including Christian de Duve (NP Medicine/Biology, 1972), George A. Olah (NP Chemistry, 1994), Gustaf 0. Arrhenius (Origins-of-Life Science, San Diego, CA, USA), Günther von Kiedrowski (Biochemistry, Bochum, Germany), Brian Johnstone (moral Theology, Rome), Paul G. Mezey (Theoretical Chemistry, Saskatoon, Canada) or (...) Julius Rebek, Jr (Chemical Biology, La Jolla, CA, USA) and Kenso Soai (Autocatalysis, Tokyo) [only to name a few] and several others, together with will-be prominences of the youngest generation as Robert Szilagyi (Stereochemistry, Stanford, CA, USA), Massimo Nardello (Theology, Modena) or Alec A. Schaerer (Philosophy, Zurich). The spectrum of the scientific approach is unusually broad. The 48 Chapters are divided into four sections: 'Definitions of Life'; 'Origin(s) of Life', - 'Basic ('background') Research' as well as 'Moral, Religious and Philosophical Aspects'. The sections are of equilibrated size and joined together by an excellent introductory chapter of the Editors: 'Dimensions of Life'. A rich source of concentrated speculations is collected in the chapter 'Short Definitions of Life', where the answers of 81 excellent scientists, all creative in this field, offer unusual intellectual fireworks. The book will become a reference work for a very broad readership ranging from college students to highly specialised research scientists and even clergymen or philosophers. (shrink)

La vie est formation de formes, la connaissance est analyse des matieres informees. Les sept etudes reunies par Canguilhem dans ce volume temoignent de cette inspiration commune: l'idee d'une irreductibilite de la vie a une serie d'analyses ou de divisions des formes vitales. La specificite du vivant engage au contraire une vision de l'objet biologique qui depasse la comprehension mecaniste des phenomenes physiques. Concue comme un approfondissement de divers enjeux conceptuels en philosophie et en histoire des sciences, La connaissance de (...) la vie est devenue une oeuvre fondamentale dont l'influence sur l'epistemologie contemporaine reste majeure.

How does science work? _Making Truth: Metaphor in Science_ argues that most laypeople, and many scientists, do not have a clear understanding of how metaphor relates to scientific thinking. With stunning clarity, and bridging the worlds of scientists and nonscientists, Theodore L. Brown demonstrates the presence and the power of metaphorical thought. He presents a series of studies of scientific systems, ranging from the atom to current topics in chemistry and biology such as protein folding, chaperone proteins, and global warming. (...) These case studies provide the basis for far-reaching conclusions about science as an intellectual and social practice and about the nature of scientific truth. (shrink)

This paper argues that biological organisation can be legitimately conceived of as an intrinsically teleological causal regime. The core of the argument consists in establishing a connection between organisation and teleology through the concept of self-determination: biological organisation determines itself in the sense that the effects of its activity contribute to determine its own conditions of existence. We suggest that not any kind of circular regime realises self-determination, which should be specifically understood as self-constraint: in biological systems, in particular, self-constraint (...) takes the form of closure, i.e. a network of mutually dependent constitutive constraints. We then explore the occurrence of intrinsic teleology in the biological domain and beyond. On the one hand, the organisational account might possibly concede that supra-organismal biological systems could realise closure, and hence be teleological. On the other hand, the realisation of closure beyond the biological realm appears to be highly unlikely. In turn, the occurrence of simpler forms of self-determination remains a controversial issue, in particular with respect to the case of self-organising dissipative systems. (shrink)

Although it may seem like a truism to assert that biology is the science that studies organisms, during the second half of the twentieth century the organism category disappeared from biological theory. Over the past decade, however, biology has begun to witness the return of the organism as a fundamental explanatory concept. There are three major causes: (a) the realization that the Modern Synthesis does not provide a fully satisfactory understanding of evolution; (b) the growing awareness of the limits of (...) reductionism in molecular biology; and (c) the renewed interest in the nature of life as a genuine scientific problem. This essay examines these recent developments and considers the new epistemological roles being played by the organism in each of them. It also reflects on what the present resurgence of the organism means for the philosophy of biology. (shrink)

'Modern History' views claim that in order for a trait X to have the proper function F, X must have been recently favored by natural selection for doing F (Griffiths 1992, 1993; Godfrey-Smith 1994). For many traits with prototypical proper functions, however, such recent selection may not have occurred, since traits may have been maintained owing to lack of variation or selection for other effects. I explore this flaw in Modern History accounts and offer an alternative etiological theory, which I (...) call the 'Continuing Usefulness' account. According to my view, a trait has the proper function F if and only if, first, the trait was favored by selection for doing F at some point (perhaps far in the past), and, secondly, the trait has recently contributed to survival and reproduction by doing F. This separates the requirement involving natural selection from the one involving the recent past, two issues that the Modern History account conflates. The clear separation allows a detailed analysis of the causal judgments and form of adaptationism that ground the etiological approach to function. (shrink)

Discussions of the functions of biological traits generally take the notion of a trait for granted. Defining this notion is a non-trivial problem. Different approaches to function place different constraints on adequate accounts of the notion of a trait. Accounts of function based on engineering-style analyses allow trait boundaries to be a matter of human interest. Accounts of function based on natural selection have typically been taken to require trait boundaries that are objectively real. After canvassing problems raised by each (...) approach, I conclude with some facts that satisfactory notions of trait must respect. (shrink)

Research has found that children possess a broad bias in favor of teleological - or purpose-based - explanations of natural phenomena. The current two experiments explored whether adults implicitly possess a similar bias. In Study 1, undergraduates judged a series of statements as "good" or "bad" explanations for why different phenomena occur. Judgments occurred in one of three conditions: fast speeded, moderately speeded, or unspeeded. Participants in speeded conditions judged significantly more scientifically unwarranted teleological explanations as correct, but were not (...) more error-prone on control items. Study 2 extended these findings by examining the relationship between different aspects of adults’ "promiscuous teleology" and other variables such as scientific knowledge, religious beliefs, and inhibitory control. Implications of these findings for scientific literacy are discussed. (shrink)

Finality, design and purpose have started to be excluded from the language of the natural sciences since the XVIIth century. Darwin succeeded in excluding them from his theory of evolution appealing to a blind and mechanical natural selection. Today, the most usual definitions for the concept of biological function take for granted that functions: 1) are not dependent on a goal; 2) are not dependent on observers, but only on nature; 3) are explicable in causal terms, either with reference to (...) the causal history of the organ (etiological definition), or with reference to its present structure and causal capabilities (dispositional definition). However, we shall see that such presuppositions cannot take into account the normative character of the concept of biological function. We show that a generalization of the concept of scientific objectivity lets us affirm that functions: 1’) are dependent on a goal; 2’) are dependent on both observers and nature; 3’) cannot be reduced to causality, nor break the laws of physics; and yet, 4) are truly objective.

ABSTRACT. This paper contemplates Organicism and its relation with molecular and evolutionary biology. We explore whether twentieth-first century biology is returning to positions held at the beginning of the twentieth century and then abandoned. The guiding line is a history of theoretical biology in which we distinguish three periods: 1. The 20s-30s, and the Theoretical Biology Club (Needham, Woodger, and Waddington, among others); 2. An intermediate period in the 60s-70s, in which, in spite of the eclosion of the molecular and (...) evolutionary biologies, there is some recovery of organicist positions, and 3. The present post-genomic situation, which is demanding a systemic approach. (shrink)
