Cicero, Lucullus 38: ‘…non potest animal ullum non adpetere id quod accommodatum ad naturam adpareat …’ From earliest childhood every man wants to possess something. One man collects horses. Another wants gold. Socrates has a passion for companions. He would rather have a good friend than a quail or a rooster. In this way, Socrates begins his interrogation of Menexenus. He then congratulates Menexenus and Lysis for each having what he himself still does not possess. How is it that one (...) gets a friend, Socrates asks? Since the nineteenth century many who have read these lines have found them repulsive. Scholars have damned the Lysis for its selfish egoism, for regarding persons as personal belongings. At the turn of the century some sought to discredit the dialogue as a forgery and a calumny. Others debated the dating of the dialogue as Socratic or Platonic, seeking whom to blame rather than whom to credit. And those who have regarded the dialogue as Platonic have tried to redeem it by detecting hints of Plato's theory of Forms. A few have attempted to salvage reputations by understanding the argument of the Lysis as a reductio of egoism, or else by invoking the loyalty of Socrates' friends and the history of Plato's friendship for Dion of Syracuse to speak up for their defence. Guthrie has condemned the dialogue as a failure of method and presentation , and Vlastos has pronounced it a failure of love: ‘The lover Socrates has in view seems positively incapable of loving others for their own sake, else why must he feel no affection for anyone whose good-producing qualities he did not happen to need?’ The Lysis appears to make no positive contribution to the Greek tradition on friendship when compared to the Symposium or the Phaedrus. And in the subsequent tradition, whatever Aristotle might have borrowed from the dialogue he uses for his own purposes. Aristotle too is quite critical of specific points raised in the Lysis. Now it might seem that Aristotle made a place for the selfish love of the Lysis in his own theory, as an inferior grade of utility love. But even this cannot be so, if we are to agree with recent studies of Aristotle's ethics. According to Aristotle, if a client is friendly to his benefactor because of the latter's usefulness, this utilitarian motive must accompany a genuine concern for the benefactor's own interest in that relation, if they are to be friends. Inferior and genuine friendship may differ in purpose but not in regard for the well-being of the beloved. This respect for the object of one's love has no parallel in the Lysis, according to the standard reading of the dialogue. (shrink)

Kant entwickelt in der Kritik der Urteilskraft eine philosophische Ästhetik, eine Theorie der organischen Natur. Die beiden scheinbar heterogenen Gegenstandsbereiche sind durch das Prinzip der reflektierenden Urteilskraft, die Idee der Zweckmäßigkeit, verbunden, die der Mensch sowohl bei der Reflexion über die schönen Gegenstände der Natur und der Kunst als auch bei seiner Erforschung der organischen Natur zugrunde legt. Da sich alle Zwecke zuletzt auf den Endzweck des Menschen als moralisches Wesen beziehen, übersteigt die dritte „Kritik" schließlich die Bereiche von Kunst (...) und Natur und berührt Fragen der Moralphilosophie und der Moraltheologie. Zusätzlich entdeckt Kant im subjektiven Vermögen der Urteilskraft jenes Bindeglied unter den menschlichen Gemütskräften, das einen architektonischen Übergang zwischen den Naturbegriffen des Verstandes in der ersten und dem Freiheitsbegriff der Vernunft in der zweiten „Kritik" ermöglicht und die theoretische und die praktische Philosophie in einem einzigen philosophischen System vereinigt. Der vorliegende kooperative Kommentar bietet eine textnahe, fortlaufende Interpretation der „Kritik der Urteilskraft". Für die 3. Auflage anlässlich des 300. Jubiläums Immanuel Kants wurden alle Beiträge überarbeitet und auf den neuesten Forschungsstand gebracht. Mit Beiträgen von: K. Ameriks, J. Bojanowski, R. Brandt, G. Cunico, M. Foessel, E.

Following Mayr (1961) evolutionary biologists often maintain that the hallmark of biology is its evolutionary perspective. In this view, biologists distinguish themselves from other natural scientists by their emphasis on why-questions. Why-questions are legitimate in biology but not in other natural sciences because of the selective character of the process by means of which living objects acquire their characteristics. For that reason, why-questions should be answered in terms of natural selection. Functional biology is seen as a reductionist science that applies (...) physics and chemistry to answer how-questions but lacks a biological point of view of its own. In this paper I dispute this image of functional biology. A close look at the kinds of issues studied in biology and at the way in which these issues are studied shows that functional biology employs a distinctive biological perspective that is not rooted in selection. This functional perspective is characterized by its concern with the requirements of the life-state and the way in which these are met. (shrink)

What are the consequences, for human moral practice, of an evolutionary understanding of that practice? By ‘moral practice’ we mean the way in which human beings think, talk and debate in moral terms. We suggest that the proper upshot of such considerations is moderate support for anti-realism in ethics.

I defend the historical definition of "function" originally given in my Language, Thought and Other Biological Categories (1984a). The definition was not offered in the spirit of conceptual analysis but is more akin to a theoretical definition of "function". A major theme is that nonhistorical analyses of "function" fail to deal adequately with items that are not capable of performing their functions.

Theory of illness causation is an important issue in all biomedical sciences, and solid etiological explanations are needed in order to develop therapeutic approaches in medicine and preventive interventions in public health. Until now, the literature about the theoretical underpinnings of illness causation research has been scarce and fragmented, and lacking a convenient summary. This interdisciplinary book provides a convenient and accessible distillation of the current status of research into this developing field, and adds a personal flavor to the discussion (...) by proposing the etiological stance as a comprehensive approach to identify modifiable causes of illness.

La teleosemántica es una teoría teleológica de las representaciones mentales, propugnada por David Papineau, que tiene como propósito ofrecer una explicación naturalista y evolucionista de dichas representaciones, en particular de las creencias. Mi objetivo será analizar las creencias y su relación con la verdad en la obra de Papineau. Según Papineau, los contenidos y las representaciones mentales, específicamente las creencias, cumplen funciones derivadas de la evolución biológica de la especie, y correlativamente, la finalidad de las creencias y los contenidos proviene (...) de las funciones biológicas que cada una de ellas tiene. De acuerdo a Papineau, para que las creencias cumplan sus funciones biológicas deben ser verdaderas, es decir, corresponder con la realidad. Defenderé la idea de que, a diferencia de lo que plantea la teleosemántica, la verdad y la falsedad, o más específicamente, los enunciados verdaderos y falsos son doxásticos, es decir, son enunciados que expresan creencias. Las creencias no tienen que ser verdaderas, sino más bien útiles, de manera que el que sean verdaderas o no es un producto secundario de la creencia. (shrink)

This article deals with a type of functional explanation, viability explanation, that has been overlooked in recent philosophy of science. Viability explanations relate traits of organisms and their environments in terms of what an individual needs to survive and reproduce. I show that viability explanations are neither causal nor historical and that, therefore, they should be accounted for as a distinct type of explanation.

This paper is concerned with reasonings that purport to explain why certain organisms have certain traits by showing that their actual design is better than contrasting designs. Biologists call such reasonings 'functional explanations'. To avoid confusion with other uses of that phrase, I call them 'design explanations'. This paper discusses the structure of design explanations and how they contribute to scientific understanding. Design explanations are contrastive and often compare real organisms to hypothetical organisms that cannot possibly exist. They are not (...) causal but appeal to functional dependencies between an organism's different traits. These explanations point out that because an organism has certain traits, it cannot be alive if the trait to be explained were replaced by a specified alternative. They can be understood from a mechanistic point of view as revealing the constraints on what mechanisms can be alive. (shrink)

I argue that there are at least four different ways in which the term ‘function’ is used in connection with the study of living organisms, namely: function as activity, function as biological role, function as biological advantage, and function as selected effect. Notion refers to what an item does by itself; refers to the contribution of an item or activity to a complex activity or capacity of an organism; refers to the value for the organism of an item having a (...) certain character rather than another; refers to the way in which a trait acquired and has maintained its current share in the population. The recognition of a separate notion of function as biological advantage solves the problem of the indeterminate reference situation that has been raised against a counterfactual analysis of function, and emphasizes the importance of counterfactual comparison in the explanatory practice of organismal biology. This reveals a neglected problem in the philosophy of biology, namely that of accounting for the insights provided by counterfactual comparison. (shrink)

Mechanistic explanation is at present the received view of scientific explanation. One of its central features is the idea that mechanistic explanations are both “downward looking” and “upward looking”: they explain by offering information about the internal constitution of the mechanism as well as the larger environment in which the mechanism is situated. That is, they offer both constitutive and contextual explanatory information. Adequate mechanistic explanations, on this view, accommodate the full range of explanatory factors both “above” and “below” the (...) target phenomenon. The aim of this paper is to demonstrate that mechanistic explanation cannot furnish both constitutive and contextual information simultaneously, because these are different types of explanation with distinctly different aims. Claims that they can, I argue, depend on several intertwined confusions concerning the nature of explanation. Particularly, such claims tend to conflate mechanistic and functional explanation, which I argue ought to be understood as distinct. Conflating them threatens to oversell the explanatory power of mechanisms and obscures the means by which they explain. I offer two broad reasons in favor of distinguishing mechanistic and functional explanation: the first concerns the direction of explanation of each, and the second concerns the type of questions to which these explanations offer answers. I suggest an alternative picture on which mechanistic explanation is understood as fundamentally constitutive, and according to which an adequate understanding of a phenomenon typically requires supplementing the mechanistic explanation with a functional explanation.

If reason is a real causal force,operative in some, but not all ofour cognition and conation, then itought to be possible to tell anaturalistic story that distinguishes themind which is moved byreason from the mind which is movedby forces other than reason.This essay proposes some steps towardthat end. I proceed by showingthat it is possible to reconcile certainemerging psychological ideasabout the causal powers of themind/brain with a venerablephilosophical vision of reason as the facultyof norms. My accountof reason is psychologistic, social, (...) and consistent with anevolutionary approach to mind. The account preserves thenormativity by deflating it. But I argue that onlysuch deflated normativity has any chance of beingmade naturalistically respectable. (shrink)

The purely theoretical notion of fitness or optimality that is employed for instance in optimization theory has come under attack from those who think that only a more historically based notion of fitness could have a central role in evolutionary explanation. They argue that the key notion is proven usefulness rather than theoretical usefulness. This paper articulates a notion of theoretical usefulness and defends its role in functional evolutionary explanations.

What could someone represent that would enable her to track, at least within limits, others' perceptions, knowledge states and beliefs including false beliefs? An obvious possibility is that she might represent these very attitudes as such. It is sometimes tacitly or explicitly assumed that this is the only possible answer. However, we argue that several recent discoveries in developmental, cognitive, and comparative psychology indicate the need for other, less obvious possibilities. Our aim is to meet this need by describing the (...) construction of a minimal theory of mind. Minimal theory of mind is rich enough to explain systematic success on tasks held to be acid tests for theory of mind cognition including many false belief tasks. Yet minimal theory of mind does not require representing propositional attitudes, or any other kind of representation, as such. Minimal theory of mind may be what enables those with limited cognitive resources or little conceptual sophistication, such as infants, chimpanzees, scrub‐jays and human adults under load, to track others' perceptions, knowledge states and beliefs.

What is the function of morality? On this question, something approaching a consensus has recently emerged. Impressed by developments in evolutionary theory, many philosophers now tell us that the function of morality is to reduce social tensions, and to thereby enable a society to efficiently promote the well-being of its members. In this paper, I subject this consensus to rigorous scrutiny, arguing that the functional hypothesis in question is not well supported. In particular, I attack the supposed evidential relation between (...) an evolutionary genealogy of morals and the functional hypothesis itself. I show that there are a great many functionally relevant discontinuities between our own culture and the culture within which morality allegedly emerged, and I argue that this seriously weakens the inference from morality’s evolutionary history to its present-day function.

Darwin'suse of final cause accords with the Aristotelian idea of finalcauses as explanatory types – as opposed to mechanical causes, which arealways particulars. In Wright's consequence etiology, anadaptation is explained by particular events, namely, its past consequences;hence, that etiology is mechanistic at bottom. This justifies Ghiselin'scharge that such versions of teleology trivialize the subject, But a purelymechanistic explanation of an adaptation allows it to appear coincidental.Patterns of outcome, whether biological or thermodynamic, cannot be explainedbytracing causal chains, even were that possible. (...) They are explicanda of aspecialkind. The form of their explanation, in statistical mechanics or by naturalselection, is not captured by statistical variants of the covering-law model orrelated models of explanation. In them as in classical teleology, types ofoutcome are cited to explain why there are outcomes of those types. But onlywhen types are explanatory by being selected for, as inexplanations of animal and human behavior as well as in Darwin's theory ofnatural selection, but not in statistical mechanics, is the explanationteleological. Darwin's theory is nontrivially teleological. (shrink)

In the dialectic of debates about the extension of life, one witnesses a predictably repeating pattern: one side appeals to a motley of variegated criteria for something’s qualifying as a living system, only to find an opposite side taking issue with the individual necessity or collective sufficiency of the proposed criteria. Some of these criteria tend to cluster with one another, while others do not: metabolism, growth and reproduction; self-organization and homeostasis; an ability to decrease internal entropy by the appropriation (...) of free energy; stimulus response suited to self-preservation and propagation; and adaptation. In competing approaches to the extension of life, these sundry criteria thus jockey for authority, with one group of theorists promoting some subset of them as essential for life, where the appeal to essence is as likely as not to be a simple modal sine qua non , and another denying that the nominated criteria are really necessary at all. The debate then stalls, because there seems to be no shared methodology for adjudicating such disputes. We may address this unhappy situation successfully by coming to appreciate that life is what we may call a core-dependent homonym. (shrink)

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)

This paper describes the development of theories of scientific explanation since Hempel's earliest models in the 1940ies. It focuses on deductive and probabilistic whyexplanations and their main problems: lawlikeness, explanation-prediction asymmetries, causality, deductive and probabilistic relevance, maximal specifity and homogenity, the height of the probability value. For all of these topic the paper explains the most important approaches as well as their criticism, including the author's own accounts. Three main theses of this paper are: (1) Both deductive and probabilistic explanations (...) are important in science, not reducible to each other. (2) One must distinguish between (cause giving) explanations and (reason giving) justifications and predictions. (3) The adequacy of deductive as well as probabilistic explanations is relative to a pragmatically given background knowledge-which does not exclude, however, the possibility of purely semantic models.

Function and teleology can be naturalized either by reference to systems with a particular type of organization or by reference to a particular kind of history. As functions are generally ascribed to states or traits according to their current role and regardless of their origin, etiological accounts are inappropriate. Here, I offer a systems-theoretical interpretation as a new version of an organizational account of functionality, which is more comprehensive than traditional cybernetic views and provides explicit criteria for empirically testable function (...) ascriptions. I propose, that functional states, traits or items are those components of a complex system, which are under certain circumstances necessary for their self-re-production. I show, how this notion can be applied in intra- and trans-generational function ascriptions in biology, how it can deal with the problems of multifunctionality and functional equivalents, and how it relates to concepts like fitness and adaptation. Finally, I argue that most intentional explanations can be treated as functional explanations. (shrink)

The basic theory of scientific understanding presented in Sections 1–2 exploits three main ideas.First, that to understand a phenomenonP (for a given agent) is to be able to fitP into the cognitive background corpusC (of the agent).Second, that to fitP intoC is to connectP with parts ofC (via arguments in a very broad sense) such that the unification ofC increases.Third, that the cognitive changes involved in unification can be treated as sequences of shifts of phenomena inC. How the theory fits (...) typical examples of understanding and how it excludes spurious unifications is explained in detail. Section 3 gives a formal description of the structure of cognitive corpuses which contain descriptive as well as inferential components. The theory of unification is then refined in the light of so called puzzling phenomena, to enable important distinctions, such as that between consonant and dissonant understanding. In Section 4, the refined theory is applied to several examples, among them a case study of the development of the atomic model. The final part contains a classification of kinds of understanding and a discussion of the relation between understanding and explanation. (shrink)

Normic Laws and the Significance of Nonmonotonic Reasoning for Philosophy of Science. Normic laws have the form ‘if A then normally B’. They have been discovered in the explanation debate, but were considered as empirically vacuous (§1). I argue that the prototypical (or ideal) normality of normic laws implies statistical normality (§2), whence normic laws have empirical content. In §3–4 I explain why reasoning from normic laws is nonmonotonic, and why the understanding of the individual case is so important here. (...) After sketching some foundations of nonmonotonic reasoning as developed by AI-researchers (§5), Iargue that normic laws are also the best way to understand ceteris paribus laws (§6). §7 deals with the difference between physical and non-physical disciplines and §9 with the difference between normicity and approximation. In §8 it is shown how nonmonotonic reasoning provides a new understanding of the protection of theories against falsification by auxiliary hypotheses. §10, finally, gives a system- and evolution-theoretical explanation of the deeper reason for the omnipresence of normic laws in practice and science, and forthe connection between ideal and statistical normality.

Abstract One of the most important things that the Darwinian revolution affected is the previous teleological thinking. In particular, the attribution of functions to various entities of the natural world with explanatory pretensions. In this change, his theory of natural selection played an important role. We all agree on that, but the diversity and heterogeneity of the answers that try to explain what Darwin did exactly with functional biology are overwhelming. In this paper I will try to show how Darwin (...) modified previous functional biology. Pre-Darwinian naturalists did not hesitate to attribute functions in which, for example, the traits of one species were in the service of other species. I will try to show that this has consequences on the discussion regarding the nature of functional language, since the main approaches, the systemic and the etiological, do not adequately account for these changes and therefore do not account for the way functional biology regulates the kind of legitimate functions. I will outline a possible new solution to this problem: appropriate functional attributions in Darwinian functional biology could be regulated by a theory or a set of laws that provide the criteria for determining its fundamental concepts. -/- Resumen: Una de las cosas más importantes a las que la revolución darwiniana afectó es el pensamiento teleológico previo. En particular, la atribución de funciones a diversas entidades del mundo natural con pretensiones explicativas. En este cambio, su teoría de la selección natural desempeñó un papel importante. Todos estamos de acuerdo en ello, pero la diversidad y heterogeneidad de las respuestas que tratan de explicar lo que Darwin hizo exactamente con la biología funcional son abrumadoras. En este artículo intentaré mostrar cómo Darwin modificó la biología funcional anterior. Los naturalistas predarwinianos no dudaban en atribuir funciones en las que, por ejemplo, los rasgos de una especie estaban al servicio de otras especies. Intentaré mostrar que esto tiene consecuencias en la discusión sobre la naturaleza del lenguaje funcional, pues los principales enfoques, el sistémico y el etiológico, no dan cuenta adecuadamente de estos cambios y, por tanto, no dan cuenta de la forma en que la biología funcional regula el tipo de funciones legítimas. Esbozaré una posible nueva solución a este problema: las atribuciones funcionales apropiadas en la biología funcional darwiniana podrían estar reguladas por una teoría o un conjunto de leyes que proporcionen los criterios para determinar sus conceptos fundamentales. -/- .

This paper looks at the nature of normal-proper functions and the role they play in theories of representational content. More specifically: I lay down two desiderata for a theory which tries to capture what's distinctive of normal-proper functions and discuss two prominent theories which claim to satisfy them. I discuss the advantages of having normal-proper functions ground a theory of representational content. And, I look at both orthodox and heterodox versions of such theories.

Robert Richards has presented a detailed defense of evolutionary ethics, a revised version of Darwin's views and a major modification of E. O. Wilson's. He contends that humans have evolved to seek the community welfare by acting altruistically. And since the community welfare is the highest moral good, humans ought to act altruistically. Richards asks us to take his empirical premises on faith and aims to show how they can justify an ethical conclusion. He identifies two necessary conditions for a (...) naturalistic justification of morality (NJ): its premises (1) must be empirical and (2) concerned with morally relevant causal factors. I argue that these two conditions are insufficient. An NJ must also appeal to teleogical or teleonomic laws which identify proper effects and reliable causes of these effects. So I supplement biological faith with an NJ that I believe has a better chance of working since faith without works is dead. (shrink)

In this article I elaborate a scientifically based moral realism that I call affordance moral realism, and I offer a promissory note that affordance moral realism is the best current explanation of morality. Affordance moral realism maintains that morality is constituted by the interaction of moral agents and moral affordances. The latter are the natural and social environments in which moral agents’ activities take place and contain the objects of moral agents’ activities whose actualizations are the manifestation of substantive moral (...) goods. In making this argument, I take a scientific naturalistic approach that includes both the natural and social sciences, aiming to make my account both methodologically and substantively naturalistic. On the subject side of my affordance view, I offer a scientific account of moral agency, one based on an extension of social cognitive theories of agency to the realm of morality. And I argue that affordance moral realism explains the nature of moral agency, its acquisition, maintenance, and successful performance. To explain its origin and maintenance, I make use of a general theory of selection that embraces biological, social, cultural, and intentional selection. On the object side, I offer a theory of moral affordances and their actualizations, employing the findings and theories of moral developmental psychology and moral psychology to understand their actualizations through the successful operations of moral agents. I conclude that a scientifically based naturalistic affordance moral realism promises to provide the best current account of morality. It is not only affordable; it’s a bargain. (shrink)

The paper argues that the evident features of all human affairs of interest to the social scientist demand Darwinian explanations. It must however be recognized that the range of regularities, models, theories that a successful Darwinian research program will inspire must be heterogeneous, operate at very different scales, identify a diversity of distinct and often unrepeated processes operating through multifarious instances of blind variation and environmental selection. There will be no canonical statement of a Darwinian theory of cultural and/or social (...) affairs. (shrink)

This review of recent work in the philosophy of science motivated by a commitment to 'naturalism' begins by identifying three key axioms and one theorem shared by philosophers thus self-styled. Owing much to Quine and Ernest Nagel, these philosophers of science share a common agenda with naturalists elsewhere in philosophy. But they have disagreed among themselves about how the axioms and the theorems they share settle long-standing disputes in the philosophy of science. After expounding these disagreements in the work of (...) Boyd, Giere, Laudan, and Kitcher, I argue that naturalism needs to look for more than mere consistency in its foundations. (shrink)

This paper argues that the consensus physicalist antireductionism in the philosophy of biology cannot accommodate the research strategy or indeed the recent findings of molecular developmental biology. After describing Wolperts programmatic claims on its behalf, and recent work by Gehring and others to identify the molecular determinants of development, the paper attempts to identify the relationship between evolutionary and developmental biology by reconciling two apparently conflicting accounts of bio-function – Wrights and Nagels (as elaborated by Cummins). Finally, the paper seeks (...) a way of defending the two central theses of physicalist antireductionism in the light of the research program of molecular developmental biology, by sharply reducing their metaphysical force.

Contemporary analyses of biological function almost invariably advocate a naturalistic analysis, grounding biological functions in some feature of the mind-independent world. Many recent accounts suggest that no single analysis will be appropriate for all cases of use and that biological teleology should be split into several distinct categories. This paper argues that such accounts have paid too little attention to the way in which functional language is used, concentrating instead on the types of situation in which it is used. An (...) example of the role of teleology in science is examined and, on the basis of conclusions drawn from this, an alternative unifying analysis is proposed. It is suggested that, contrary to naturalistic accounts, teleology in biology carries no ontological commitment whatsoever to any class of mind-independent entities or properties. Instead, it is best regarded as a methodological device which is used to focus interest, formulate research perspectives and facilitate the structuring of certain questions or types of question that are pertinent in a given context of interest.

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.

For the past 40 years, philosophers have generally assumed that a key to understanding mental representation is to develop a naturalistic theory of representational content. This has led to an outlook where the importance of content has been heavily inflated, while the significance of the representational vehicles has been somewhat downplayed. However, the success of this enterprise has been thwarted by a number of mysterious and allegedly non-naturalizable, irreducible dimensions of representational content. The challenge of addressing these difficulties has come (...) to be known as the “hard problem of content” (Hutto & Myin, 2012), and many think it makes an account of representation in the brain impossible. In this essay, I argue that much of this is misguided and based upon the wrong set of priorities. If we focus on the functionality of representational vehicles (as recommended by teleosemanticists) and remind ourselves of the quirks associated with many functional entities, we can see that the allegedly mysterious and intractable aspects of content are really just mundane features associated with many everyday functional kinds. We can also see they have little to do with content and more to do with representation function. Moreover, we can begin to see that our explanatory priorities are backwards: instead of expecting a theory of content to be the key to understanding how a brain state can function as a representation, we should instead expect a theory of neural representation function to serve as the key to understanding how content occurs naturally.

David Papineau's model of scientific reduction, contrary to his intent, appears to enable a naturalist realist account of the primitive normativity involved in a biological adaptation's being “for” this or that (say the eye's being for seeing). By disabling the crucial anti‐naturalist arguments against any such reduction, his model would support a cogni‐tivist semantics for normative claims like “The heart is for pumping blood, and defective if it doesn't.” No moral claim would follow, certainly. Nonetheless, by thus “pressing from below” (...) we may learn something about moral normativity. For instance, suppose non‐cognitivists like Mackie are right that the semantics of normative claims should be “unified”: if the semantics of moral claims is non‐cognitivist, so too is that of all normative claims. Then, assuming that a naturalist reduction does yield a sound cognitivist account of the primitive normativity, it would follow that our semantics of moral claims is cognitivist as well. (shrink)

This paper addresses a fundamental line of research in neuroscience: the identification of a putative neural processing core of the cerebral cortex, often claimed to be “canonical”. This “canonical” core would be shared by the entire cortex, and would explain why it is so powerful and diversified in tasks and functions, yet so uniform in architecture. The purpose of this paper is to analyze the search for canonical explanations over the past 40 years, discussing the theoretical frameworks informing this research. (...) It will highlight a bias that, in my opinion, has limited the success of this research project, that of overlooking the dimension of cortical development. The earliest explanation of the cerebral cortex as canonical was attempted by David Marr, deriving putative cortical circuits from general mathematical laws, loosely following a deductive-nomological account. Although Marr’s theory turned out to be incorrect, one of its merits was to have put the issue of cortical circuit development at the top of his agenda. This aspect has been largely neglected in much of the research on canonical models that has followed. Models proposed in the 1980s were conceived as mechanistic. They identified a small number of components that interacted as a basic circuit, with each component defined as a function. More recent models have been presented as idealized canonical computations, distinct from mechanistic explanations, due to the lack of identifiable cortical components. Currently, the entire enterprise of coming up with a single canonical explanation has been criticized as being misguided, and the premise of the uniformity of the cortex has been strongly challenged. This debate is analyzed here. The legacy of the canonical circuit concept is reflected in both positive and negative ways in recent large-scale brain projects, such as the Human Brain Project. One positive aspect is that these projects might achieve the aim of producing detailed simulations of cortical electrical activity, a negative one regards whether they will be able to find ways of simulating how circuits actually develop.

I provide two arguments against value-free naturalism. Both are based on considerations concerning biological teleology. Value-free naturalism is the thesis that both (1) everything is, at least in principle, under the purview of the sciences and (2) all scientific facts are purely non-evaluative. First, I advance a counterexample to any analysis on which natural selection is necessary to biological teleology. This should concern the value-free naturalist, since most value-free analyses of biological teleology appeal to natural selection. My counterexample is unique (...) in that it is likely to actually occur. It concerns the creation of synthetic life. Recent developments in synthetic biology suggest scientists will eventually be able to develop synthetic life. Such life, however, would not have any of its traits naturally selected for. Second, I develop a simple argument that biological teleology is a scientific but value-laden notion. Consequently, value-free naturalism is false. I end with some concluding remarks on the implications for naturalism, the thesis that (1). Naturalism may be salvaged only if we reject (2). (2) is a dogma that unnecessarily constrains our conception of the sciences. Only a naturalism that recognizes value-laden notions as scientifically respectable can be true. Such a naturalism is a functional naturalism. (shrink)

On this view, natural selection explains the adaptedness of individuals, not by explaining why the individuals that exist have the adaptations they do, but rather by explaining why the individuals that exist are the ones with those adaptations. This paper argues that this ‘Negative’ view of natural selection ignores the fact that natural selection is a cumulative selection process. So understood, it explains how the genetic sequences (...) that individuals inherit and that are responsible for their complex (and co-adapted) adaptations first arose in the gene-pool. (shrink)
