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. (shrink)

Comments on Karen Neander's A Mark of the Mental.

This is a response to Christie, Brusse, et al., ‘Are biological traits explained by their “selected effect” functions?’ The interest of their paper is that it draws our attention to those cases in which changes in a population that are brought about by natural selection in turn bring about changes in the environment that alter the selectionist pressures that were responsible for the original changes. Much of the paper, however, is an argument that the notion of a ‘proper (...) function’ introduced in my Language, Thought, and Other Biological Categories (LTOBC), exhibits deep misunderstandings about the actual workings of natural selection. Very little that they say about ‘proper functions’ and related notions from LTOBC is correct, however. I will not list the errors but I will try to make my uses of ‘proper function’ and certain related terms clearer. (shrink)

This paper argues that proper functions are proximal functions. In other words, it rejects the notion that there are distal biological functions – strictly speaking, distal functions are not functions at all, but simply beneficial effects normally associated with a trait performing its function. Once we rule out distal functions, two further positions become available: dysfunctions are simply failures of proper function, and pathological conditions are dysfunctions. Although elegant and seemingly intuitive, this (...) simple view has had surprisingly little uptake in the literature. Indeed, our position departs from that of almost every theorist who has engaged with the issue at any depth. We start by presenting three arguments for the position that proper functions are proximal: one from the specificity of functions, one from their relation to intervention, and one from their relation to pathology. We then consider two case studies evidencing the trouble that accepting distal functions causes for philosophical reflection on the nature of pathological conditions. Finally, we anticipate and respond to three objections: that there can be failure of function without dysfunction; that our account is unacceptably revisionary in respect of normal function-talk; and that our thesis over-generalises from a narrow set of cases.

Proper functionalism explicates epistemic warrant in terms of the function and normal functioning of the belief-forming process. There are two standard substantive views of the sources of functions in the literature in epistemology: God (intelligent design) or Mother Nature (evolution by natural selection). Both appear to confront the Swampman objection: couldn’t there be a mind with warranted beliefs neither designed by God nor the product of evolution by natural selection? Is there another substantive view that avoids the (...) Swampman objection? There are two. The first is the generalized selected-effects theory of functions. The second is the organizational theory of functions. Both, however, require some history to assign functions, for both are etiological theories of functions: past effects help explain current function. Swampman can then acquire functions, perhaps soon after creation, though he has none at the moment of inception. (shrink)

This paper argues that a minimal notion of function and a notion of normal-proper function are used in explaining how bodies and brains operate. Neither is Cummins’ notion, as originally defined, and yet his is often taken to be the clearly relevant notion for such an explanatory context. This paper also explains how adverting to normal-proper functions, even if these are selected functions, can play a significant scientific role in the operational explanations of complex (...) systems that physiologists and neurophysiologists provide, despite a lack of relevant causal efficacy on the part of such functions.

Montague [7] translates English into a tensed intensional logic, an extension of the typed -calculus. We prove that each translation reduces to a formula without -applications, unique to within change of bound variable. The proof has two main steps. We first prove that translations of English phrases have the special property that arguments to functions are modally closed. We then show that formulas in which arguments are modally closed have a unique fully reduced -normal form. As a corollary, (...) translations of English phrases are contained in a simply defined proper subclass of the formulas of the intensional logic. (shrink)

Standard semantics of proper names assigns them the function of reference to individual things. This presupposes that to understand the meaning of a proper name is to understand what it denotes in the context of its referential use. But unambiguous identification of the referent of a proper name in its normal (referential) use looks like an unsolvable problem. Senses associated with referential uses of such names don't allow ascribing them singular referents in their contexts; and what (...) concerns contexts themselves, they either don't contain proper referents at all or contain more than one, thus being referentially ambiguous. Some philosophers of language believe that the main problem for the standard semantics of proper names is that they assign them referents of wrong kind: that these, for instance, should be rather abstract entities, i.e. sets, than individual things. In this paper I try to argue that the choice of an alternative semantics for proper names does not solve the main problem with their meanings, i.e. that of their referential ambiguity. On the one hand even in the most transparent contexts there is always available an alternative referent to be assigned to the proper name's use along with some standard or default one; the fact that we prefer some standard interpretation (when we actually do) over alternative ones reflects at best that certain semantic theories contribute more substantially to ordinary communication in comparison with others. This does not yet imply that they better explain meanings of proper names. On the other hand there is also no good explanation of a phenomenon of reference to a particular thing as such: we still don't understand how a name may become referring to one and the same particular thing in many different situations for many different agents of its use etc., and how the thing may literally become a bearer of a name.

“Neurodiversity” is associated with the struggle for the civil rights of all those diagnosed with neurological or neurodevelopmental disorders. Two basic approaches in the struggle for what might be described as “neuro-equality” are taken up in the literature: There is a challenge to current nosology that pathologizes all of the phenotypes associated with neurological or neurodevelopmental disorders ); there is a challenge to those extant social institutions that either expressly or inadvertently model a social hierarchy where the interests or needs (...) of individuals are ranked relative to what is regarded as properly functioning cognitive capacities. In this paper, we explore some of the reasons justifying which make it an important tool for achieving greater neuro-equality, while still recognizing its limitations for achieving this goal. Particularly, we explore how an appeal to functionality and neurological diversity can support a re-seeing of at least certain forms of ASD. (shrink)

This paper argues for the general proper functionalist view that epistemic warrant consists in the normal functioning of the belief-forming process when the process has forming true beliefs reliably as an etiological function. Such a process is reliable in normal conditions when functioning normally. This paper applies this view to so-called testimony-based beliefs. It argues that when a hearer forms a comprehension-based belief that P (a belief based on taking another to have asserted that P) through the (...) exercise of a reliable competence to comprehend and filter assertive speech acts, then the hearer's belief is prima facie warranted. The paper discusses the psychology of comprehension, the function of assertion, and the evolution of filtering mechanisms, especially coherence checking. (shrink)

G. Jäger gave in Arch. Math. Logik Grundlagenforsch. 24 , 49-62, a recursive notation system on a basis of a hierarchy Iαß of α-inaccessible regular ordinals using collapsing functions following W. Buchholz in Ann. Pure Appl. Logic 32 , 195-207. Jäger's system stops, when ordinals α with Iα0 = α enter. This border is now overcome by introducing additional a hierarchy Jαß of weakly inaccessible Mahlo numbers, which is defined similarly to the Jäger hierarchy. An ordinal μ is called (...) Mahlo, if every normal-function f : μ → μ has regular fixpoints. Collapsing is defined for both Mahlo and simply regular ordinals such that for every Mahlo ordinal μ out of the J-hierarchy Ψμα is a regular σ such that Iσ0 = σ. For these regular σ again collapsing functions Ψσ are defined. To get a proper systematical order into the collapsing procedure, a pair of ordinals is associated to σ and α, and the definition of Ψσα is given by recursion on a suitable well-ordering of these pairs. Thus a fairly large system of ordinal notations can be established. It seems rather straightforward, how to extend this setting further. (shrink)

What is the best account of process reliabilism about epistemic justification, especially epistemic entitlement? I argue that entitlement consists in the normal functioning (proper operation) of the belief-forming process when the process has forming true beliefs reliably as an etiological function. Etiological functions involve consequence explanation: a belief-forming process has forming true beliefs reliably as a function just in case forming-true beliefs reliably partly explains the persistence of the process. This account paves the way for avoiding standard (...) objections to process reliabilism and situations epistemic entitlement within a normative framework of functions and functional norms. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Human Gene TherapyMary Carrington Coutts (bio)On September 14, 1990, researchers at the U.S. National Institutes of Health (NIH) performed the first approved gene therapy procedure on a four-year-old girl named Ashanti DeSilva. Born with a rare genetic disease, severe combined immune deficiency (SCID), Ashanti lacked a healthy immune system and was extremely vulnerable to infection. Children with SCID usually develop overwhelming infections and rarely survive to adulthood; even a (...) common childhood illness like chicken pox is life-threatening. Ashanti led a cloistered existence, avoiding contact with people outside her family, remaining in the sterile environment of her home, and battling frequent illnesses with massive amounts of antibiotics.In Ashanti's gene therapy procedure, her own white blood cells were genetically modified and then infused back into her bloodstream. Laboratory tests show that the therapy has strengthened Ashanti's immune system. She no longer has recurrent colds, has been allowed to attend school, and has been immunized against whooping cough. This gene therapy procedure is not a cure, however. The genetically-treated white blood cells only survive for a few months and must then be replaced, but Ashanti's future is much brighter because of the new therapy (VI, Thompson [The First] 1993).Although this simplified description of Ashanti's gene therapy procedure sounds like a happy ending, it is little more than an optimistic chapter in a long story. The road to the first approved gene therapy procedure was rocky and fraught with controversy. The biology of human gene therapy is very complex, and there are still many techniques that need to be developed and diseases that need to be understood more fully before gene therapy is well established. The public policy debate surrounding the possible use of genetically engineered material in human subjects is equally complex. Major participants in the debate come from the fields of biology, government, law, medicine, philosophy, politics, and religion, each bringing different views to the discussion.In studying the ethics of gene therapy, one should draw a distinction between [End Page 63] therapy on somatic (non-reproductive) cells and germ (reproductive) cells. Only the germ cells carry the genes that will be passed on to the next generation. Reactions to gene therapy have varied widely. Some commentators on gene therapy object to any form of genetic manipulation, no matter how well-intentioned (VI, Rifkin 1983). Another reaction is to allow the use of somatic-cell therapy, but not to approve the use of germ-line therapy, which could have unforeseeable effects on future generations. A different stance is that, with proper regulation and safeguards, germ-line gene therapy is a logical extension of the progress made to date and that it is an ethically acceptable procedure.TechniquesTo date, 43 research protocols have been approved for somatic-cell gene therapy in the United States. The techniques employed in each protocol vary, but in general a virus is used as a "vector" to insert the desired gene into the DNA of the patient's cells, in order to compensate for a defective gene. For Ashanti's gene therapy, this technique involved obtaining white blood cells and introducing properly functioning genes into as many of the cells as possible. The normal genes were delivered through the use of a specially-engineered virus.Although similar techniques are used in germ-line gene therapy, the procedure is more difficult. There are two basic ways to perform germ-line gene therapy: (1) to treat a preimplantation embryo that carries a serious genetic defect before its implantation in the mother, which necessitates the use of in vitro fertilization techniques; or (2) to treat the germ cells (sperm or egg cells) of afflicted adults so that the genetic defects would not be passed on to their offspring, which requires the technical expertise to delete the defective gene and insert a properly functioning replacement. Because of the complexity of the procedures involved and the attendant ethical controversy, germ-line therapy is not currently performed.Candidate Diseases for Gene TherapyAt present, gene therapy is likely to be most successful in treating diseases that are caused by single-gene defects and has been approved for treating diseases such...

The current essay introduces the guidance theory of representation, according to which the content and intentionality of representations can be accounted for in terms of the way they provide guidance for action. The guidance theory offers a way of fixing representational content that gives the causal and evolutionary history of the subject only an indirect role, and an account of representational error, based on failure of action, that does not rely on any such notions as proper functions, ideal (...) conditions, or normal circumstances. Moreover, because the notion of error is defined in terms of failure of action, the guidance theory meets the “meta-epistemological requirement” that representational error should be potentially detectable by the representing system itself. In this essay, we offer a brief account of the biological origins of representation, a formal characterization of the guidance theory, some examples of its use, and show how the guidance theory handles some traditional problem cases for representation: the representation of fictional and abstract entities. Being both representational and actiongrounded, the guidance theory may provide some common ground between embodied and cognitivist approaches to the study of the mind. (shrink)

How do scientific explanations for beliefs affect people's confidence that those beliefs are true? For example, do people think neuroscience-based explanations for belief in God support or challenge God's existence? In five experiments, we find that people tend to think explanations for beliefs corroborate those beliefs if the explanations invoke normally-functioning mechanisms, but not if they invoke abnormal functioning (where “normality” is a matter of proper functioning). This emerges across a variety of kinds of scientific explanations and beliefs (religious, (...) moral, and scientific). We also find evidence that these effects can interact with people's prior beliefs to produce motivated judgments. (shrink)

In ‘Of Sensory Systems and the “Aboutness” of Mental States’, Kathleen Akins (1996) argues against what she calls ‘the traditional view’ about sensory systems, according to which they are detectors of features in the environment outside the organism. As an antidote, she considers the case of thermoreception, a system whose sensors send signals about how things stand with themselves and their immediate dermal surround (a ‘narcissistic’ sensory system); and she closes by suggesting that the signals from many sensory systems may (...) not in any familiar sense be about anything at all. Her presentation of the issues, however, overlooks resources available to ‘the traditional view’—or so I shall argue. Akins’s own thumbnail sketch of what is wrong with the traditional view is that it asks, concerning a given sensory system, ‘what is it detecting?’, when we should instead be asking ‘what is it doing?’ (352). Her point is that on the traditional view the function of a sensory system—what it's ‘for’—is to detect or indicate (values of) features of the outside environment. But at least on one version of the traditional view—namely Ruth Millikan’s—this would never be the sole or main proper function of a sensory system. (Akins does not list Millikan as a traditionalist, but Millikan fits squarely Akins’s description of them, since she believes in a naturalistic theory of aboutness and thinks it should begin with the senses.) For Millikan (1989, 1993), the proper function of a sensory system is in the first instance enabling behavioural systems—in the simplest case, motor routines—to perform their proper function. This they do, roughly, by switching on and steering the behavioural routines. Where features of the outside environment come in is as Normal (= assumed-by-the-design) conditions for the successful performance of the sensory system's proper function. That is, the only strategy for switching on and steering that is simple enough for evolution to have hit upon it, and reliable enough for evolution to have liked it, is a strategy which gears the steering to (values of) features of the outside environment. But as soon as one starts fleshing out the details of this story, one notices that they are probably quite different in the case of thermoreception from how they are with ‘distance’ senses such as vision and olfaction--a point which Akins overlooks..

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Adam Smith Reconsidered: History, Liberty, and the Foundations of Modern Politics by Paul SagarJames A. HarrisPaul Sagar. Adam Smith Reconsidered: History, Liberty, and the Foundations of Modern Politics. Princeton, NJ: Princeton University Press, 2022. Pp. xii + 229. Hardback, $37.00.Paul Sagar's invigorating book is a reconsideration of Adam Smith in the sense that it challenges much that is received wisdom in current scholarship. First and foremost, it rejects (...) the idea that Smith was preeminently a moral philosopher concerned with the threat to civic virtue posed by commercial society, and yet intent on giving commercial society a moral vindication nevertheless. Sagar—rightly, in my view—wants us to recognize Smith as having been a political thinker. Too much work on Smith still assumes that there is not much to say [End Page 323] about his political thought because he regarded all but the most minimal government as an obstacle to the proper functioning of markets. Smith is supposed to be a "classical liberal" bent on preserving as much natural liberty as possible in the face of government's relentless overextension of its powers of regulation. In Adam Smith's Politics: An Essay in Historiographic Revision (Cambridge: Cambridge University Press, 1978), Donald Winch rejected that approach to Smith in favor of a portrait of the author of The Theory of Moral Sentiments and The Wealth of Nations as an eighteenth-century thinker with an eighteenth-century thinker's concerns. Sagar's project is quite different. This is a book on Smith's political thought that does not once deploy the term 'Whig.' Sagar's Smith does not wholly float free of his historical situation—the questions he addresses are those posed by the end of feudalism and the advent of modernity—but situating him in the particular circumstances of Britain in the age of revolutions is not Sagar's concern. As Sagar sees it, the fundamental issues addressed by Smith's political thought concern the distinctive form taken by commercial society in the modern era. Smith, according to Sagar, held that all advanced societies are commercial societies. Commercial society as such needed no vindication. The question, rather, was what kind of commercial society a modern state wanted to be. That was a political question insofar as it was a question about the kind of freedom that mattered and about the kind of institutions needed to make that freedom a reality.Defined in maximally general terms, freedom for Smith was the absence of domination, where domination is understood as a lack of security in respect of one's physical safety and possessions. The condition of the poor and powerless had always been one of subjection to the will of the rich and powerful. What changed that, according to Smith, was implementation of the rule of law. This is in itself not a new reading of Smith, but what distinguishes Sagar's version of it is the care with which he examines both the place of the rule of law in Smith's historical account of the emergence of liberty in modern Europe and the precise nature of the connection between the rule of law and freedom. First, on Sagar's view, there needed to be a comprehensive picture of domination and slavery, which had been the normal condition of almost everyone for almost all of human history. Then there needed to be an explanation of how it was that, at one particular historical moment, domination was slowly but surely challenged by the emergence of law and law courts considered as independent of political power. In England, this was the story of the common law and of judges who held office for life, rather than at the pleasure of traditional possessors of power. It was the story of security in property, of the backing of property by law, and it was a largely urban story, of burghers who managed to enlist monarchs on their side in the battle against the barons. It was, in other words, in large part a medieval story, and one consequence is that there was more to say about the rise of liberty in the modern age than that it was caused inadvertently by...

Jonathan Kvanvig has argued that what he terms “doxastic” theories of epistemic justification fail to account for certain epistemic features having to do with evidence. I’m going to give an argument roughly along these lines, but I’m going to focus specifically on proper function theories of justification or warrant. In particular, I’ll focus on Michael Bergmann’s recent proper function account of justification, though the argument applies also to Alvin Plantinga’s proper function account of warrant. The epistemic features (...) I’m concerned about are experiences that should generate a believed defeater but don’t. I’ll argue that proper functionalism as it stands cannot account for the epistemic effects of these defeating experiences—or, at least, that it can only do so by embracing a deeply implausible view of our cognitive faculties. I’ll conclude by arguing that the only plausible option Bergmann has for modifying his theory undercuts the consideration that motivates proper functionalism in the first place. (shrink)

Dogmatism about perceptual warrant claims that if a subject has a perceptual experience as of p, then this can provide immediate and defeasible warrant to believe that p. Crispin Wright has put forward three original criticisms of this view. First, and most extensively, Wright argues that the dogmatist is committed to implausible answers to questions about when subjects are in a position to claim warrant to believe certain propositions. Second, he claims that the view is too permissive in assigning warrant (...) in cases in which a subject has balanced evidence regarding the proper functioning of her perceptual system. Finally, he argues that the oft-included restriction of immediate and defeasible dogmatic warrant to perceptually basic beliefs results in a view that is unable to claim that beliefs about normal external world objects are warranted. I argue that none of these objections can be sustained and that dogmatism does not have the problematic consequences that Wright alleges. (shrink)

In an earlier chapter, the author argues that naturalists can justifiably accept realism about material objects only if the methods of science justify belief in intrinsic modal properties. One suggestion as to how they might do this is as follows: beliefs attributing intrinsic modal properties to material objects are justified because their truth provides a good explanation for the existence of proper functions in nature. This examines this suggestion and argues that, except in the case of objects that (...) are the products of design, proper functions are not empirically detectable. (shrink)

Designers’ intentions are important for determining an artifact’s proper function (i.e., its perceived real function). However, there are disagreements regarding why. In one view, people reason causally about artifacts’ functional outcomes, and designers’ intended functions become important to the extent that they allow inferring outcomes. In another view, people use knowledge of designers’ intentions to determine proper functions, but this is unrelated to causal reasoning, having perhaps to do with intentional or social forms of reasoning (e.g., (...) authority). Regarding these latter social factors, researchers have proposed that designers’ intentions operate through a mechanism akin to social conventions, and that therefore both are determinants of proper function. In the current work, participants learned about an object’s creation, about social conventions for its use and about a specific episode where the artifact was used. The function implemented by the user could be aligned with the designer’s intended function, the social convention, both, or neither (i.e., an opportunistic use). Importantly, the use episode always resulted in an accident. Data show that the accident negatively affected proper function judgments and perceived efficiency for conventional and opportunistic functions, but not for designers’ intended functions. This is inconsistent with the view that designers’ intentions are conceptualized as causes of functional outcomes and with the idea that designers’ intentions and social conventions operate through a common mechanism.

According to Alvin Plantinga, the cornerstone of epistemology is the proper functioning of our cognitive faculties in accordance with the design plan. In this paper I will explore two aspects of the design plan that are of central relevance to the acquisition of warranted true beliefs. In the first place, perceptual beliefs were supposed to be taken in the basic way and should therefore constitute highly warranted true beliefs. Scale errors in young children pose serious problems for this argument, (...) while they show that part of the visual system may be misguided by perceptual beliefs, as a normal part of the development of the human design plan. Secondly, the ascription of mental states to other persons does not depend on deductive or inductive inference from behaviour. However, the discovery of so-called ‘mirror-neurons' suggests that motor simulation of observed behaviour plays a crucial role in understanding the intentions of others. I conclude by arguing for a refinement of the notion of ‘design plan', guided by recent approaches in cognitive science that should make Plantinga's externalist account at least falsifiable.

First, I argue that we should take reductive materialism and the Lockean view of personal identity seriously. But, these positions appear in tension. Second, I argue a plausible way to reconcile them is to embrace a novel kind of animalism that I call neural animalism. This says that I am identical to my properly functioning (...) brain. (shrink)

You can sometimes have and be moved by desires which you in some sense disown. The problem is whether we can make sense of these ideas of---as I will say---ownership and rejection of a desire, without appeal to a little person in the head who is looking on at the workings of her desires and giving the nod to some but not to others. Frankfurt's proposed solution to this problem, sketched in his 1971 article, has come to be called the (...) hierarchical model. Indeed, it seems that, normally, if an agent's relevant higher-order attitudes are not to some extent shaped by her evaluative reflections and judgments her agency will be flawed. But this suggests a Platonic challenge to the hierarchical account of ownership. The challenge is to explain why we should not see such evaluative judgments---rather than broadly Frankfurtian higher-order attitudes---as the fundamental basis of ownership or rejection of desire. I do think that a systematic absence of connection between higher-order Frankfurtian attitude and evaluative judgment would be a breakdown in proper functioning. But I want to explain how we can grant this point and still block the Platonic challenge. (shrink)

No two individuals with the autism diagnosis are ever the same—yet many practitioners and parents can recognize signs of ASD very rapidly with the naked eye. What, then, is this phenotype of autism that shows itself across such distinct clinical presentations and heterogeneous developments? The “signs” seem notoriously slippery and resistant to the behavioral threshold categories that make up current assessment tools. Part of the problem is that cognitive and behavioral “abilities” typically are theorized as high-level disembodied and modular (...) class='Hi'>functions—that are assessed discretely (impaired, normal, enhanced) to define a spectral syndrome. Even as biology reminds us that organic developing bodies are not made up of independent switches, we remain often seduced by the simplicity of mechanistic and cognitive models. Developmental disorders such as autism have accordingly been theorized as due to different modular dysfunctions—typically of cortical origin, i.e., failures of “theory of mind” (Baron-Cohen et al., 1985), of the “mirror neuron system” (Ramachandran and Oberman, 2006), of “weak central coherence” (Happe and Frith, 2006) or of the balance of “empathizing” and “systemizing” (Baron-Cohen, 2009), just to list a few. -/- The broad array of autonomic (Ming et al., 2005; Cheshire, 2012) and sensorimotor (Damasio and Maurer, 1978; Maurer and Damasio, 1982; Donnellan and Leary, 1995; Leary and Hill, 1996; Donnellan and Leary, 2012; Donnellan et al., 2012) differences experienced and reported by people with autism have by such theories typically been sidelined as “co-morbidities,” possibly sharing genetic causes, but rendered as incidental and decisively behaviorally irrelevant symptoms—surely disconnected from cognition. But what if the development of cortically based mental processes and autonomous control relies on the complexities and proper function of the peripheral nervous systems? Through such an “embodied” lens the heterogeneous symptoms of autism invites new interpretations. We propose here that many behavioral-level findings can be re-defined as downstream effects of how developing nervous systems attempt to cope and adapt to the challenges of having various noisy, unpredictable, and unreliable peripheral inputs.

Alvin Plantinga's externalist analysis of epistemic warrant centres on the proper function of the relevant belief-forming mechanism, where proper function is fixed relative to the design plan of the organism in question. He has set this analysis against reliabilism, the other leading externalist contender for the analysis of warrant. Though Plantinga's discussion advances the field of epistemology in a number of important ways, his treatment of warrant is limited by his assumption of creationism in his understanding of design (...) and function. Further, analyses of epistemic warrant focusing on function over reliability either fail at handling problem cases reliabilism can handle, or fail to improve on problem cases for reliabilism. Thus no proper functionalist analysis like Plantinga's can supersede a well-constructed reliabilist analysis. (shrink)

Both biological traits and artifacts have proper functions. But accounts of proper function are typically based on the biological case. So adapting these accounts to the artifact case requires finding cultural analogues of biological concepts. This can go wrong in two ways. The biological concepts may not pick out either biological or cultural proper functions correctly; or they may have no cultural analogues. I argue that things have gone wrong in the first way with regard (...) to selection and in the second way with regard to fitness. Finally, I argue that the only way forward is to examine the phenomena of reproduction and use in material culture. -/- . (shrink)

On dit souvent que, tandis que la biologie de l'évolution utilise un concept étiologique de fonction (la fonction d'un trait biologique n'est autre que son effet sélectionné), la physiologie prend appui sur un autre concept de fonction, celui de rôle causal. Cependant, un examen plus attentif montre que le concept non normatif de rôle causal n'est pas ce dont la physiologie générale ou la neurophysiologie ont besoin. Ces disciplines font un large usage de notions comme celles de bon fonctionnement, de (...) fonctionnement normal, de fonctionnement perturbé ou de trouble fonctionnel. Il semble ainsi qu'un concept normatif comme le concept étiologique n'est pas seulement utile dans le contexte d'explications téléologiques ou évolutionnistes, mais aussi dans celui d'explications mécanistes ou opérationnelles telles qu'elles sont couramment proposées par la physiologie. La différence entre types d'explication n'est pas une différence entre deux concepts de fonction. En particulier, l'analyse physiologique serait une tâche impossible si elle devait prendre en compte toutes les relations causales à l'intérieur de l'organisation fonctionnelle de chaque système biologique. Pour résoudre ce problème, la physiologie doit être une analyse du fonctionnement normal du système, quelle que soit la part d'idéalisation nécessaire. La notion de bon fonctionnement, conçu comme le produit de l'histoire évolutive, nous aide en particulier à comprendre pourquoi les systèmes qui fonctionnent bien se ressemblent, et pourquoi les systèmes qui dysfonctionnent peuvent le faire de tant de façons différentes. It is often claimed that although evolutionary biology uses an etiological concept of function (according to etiological theory, the function of a biological feature is its selected effect), physiology relies on a different concept of function, the causal role concept. However, upon closer scrutiny, it appears that the non-normative causal role concept is not what is needed by physiology or neurophysiology. These disciplines make a wide use of normative notions like proper functioning, normal functioning, impaired functioning, or functional disorders. In this case, it seems that a normative concept like the etiological concept is not only useful in the context of teleological or evolutionary explanations, but also in the context of mechanical or operational explanations as they are routinely offered by physiology. The difference between types of explanations is not a difference between two kinds of concepts of function. In particular, physiological analysis would be an impossible task if it had to take into account all causal links within the functional organization of each biological system. To solve this problem, physiology has to be the analysis of the proper or normal functioning of the system, even if normal functioning is usually obtained through a process of idealization. The notion of proper functioning, conceived as the product of evolutionary history, helps us understand, among other things, why properly functioning systems tend to be similar, and why malfunctioning systems may differ in so many different ways.

Natural selection comes in degrees. Some biological traits are subjected to stronger selective force than others, selection on particular traits waxes and wanes over time, and some groups can only undergo an attenuated kind of selective process. This has downstream consequences for any notions that are standardly treated as binary but depend on natural selection. For instance, the proper function of a biological structure can be defined as what caused that structure to be retained by natural selection in the (...) past. We usually think of proper functions in binary terms: storing bile is a function of the gall bladder, but making stones is not. However, if functions arise through natural selection, and natural selection comes in degrees, then a binary approach to proper functions is in tension with the biological facts. In order to resolve this tension, we need to revise our standard accounts of proper function. In particular, we may have to seriously consider the possibility that functions themselves come in degrees, in spite of the ramifications this will have for the way we speak about functions and related concepts such as dysfunction, disease, and teleosemantic content.

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

The etiological approach to ‘proper functions’ in biology can be strengthened by relating it to Robert Cummins' general treatment of function ascription. The proper functions of a biological trait are the functions it is assigned in a Cummins-style functional explanation of the fitness of ancestors. These functions figure in selective explanations of the trait. It is also argued that some recent etiological theories include inaccurate accounts of selective explanation in biology. Finally, a generalization of (...) the notion of selective explanation allows an analysis of the proper functions of human artifacts. (shrink)

In this paper I assess the explanatory powers of theories of function in the context of products that may result from synthetic biology. The aim is not to develop a new theory of functions, but to assess existing theories of function in relation to a new kind of biological and artifactual entity that might be produced in the not-too-distant future by means of synthetic biology. The paper thus investigates how to conceive of the functional nature of living systems that (...) are not the result of evolution by natural selection, or instantly generated by cosmic coincidence, but which are products of intelligent design. The paper argues that the aetiological theory of proper functions in organisms and artifacts is inadequate as an account of proper functions in such ‘Paley organisms’ and defends an alternative organisational approach. The paper ends by considering the implications of the discussion of biological function for questions about the interests and moral status of non-sentient organisms. (shrink)

Rawls’s notion of civil disobedience, which still dominates the literature on this subject, comprises at least these three characteristics: it involves breaking the law, is non-violent and public. But implicit in this notion is a certain tension: it shows pessisimism about the proper functioning of the public sphere as earlier normal appeals have failed, but it also displays a certain optimism about its proper functioning as it assumes that civil disobedience may be effective. In my paper I (...) argue that Rawls cannot explain how civil disobedience may be effective as a public appeal for social justice because he does not fully understand what it means for civil disobedience to be public in relation to the public sphere. His analysis would require an additional notion of publicity which, as I argue, is the notion of hermeneutical publicity. From a Bourdieusian perspective I then make a case for the claim that public spheres always suffer from hermeneutic invisibility. This may explain why non-violent appeals for social justice fail as dialogical practices. Finally I suggest how we nevertheless could understand that civil disobedience can be effective as a dialogical practice. (shrink)

The author argues that Schauer's understanding of appropriate empiricism and relatedly what he wishes to take from the positivist classics might have an even more reductive impact on legal philosophical inquiry than the legal positivist quest to confine such inquiry to a search for necessary and sufficient conditions. The argument is based on the example of the legal order of the Arab territories occupied by Israel. In the author's view, this legal order is very close to what Schauer regards as (...) the normal case of a properly functioning legal order and in its closeness one can discern the flaws in his argument.

In this paper, I develop and motivate a novel formulation of the safety condition in terms of etiological proper function. After testing this condition against the most pressing objections to safety-theoretic accounts of knowledge in the literature, my conclusion will be the following: once safety is suitably understood in terms of etiological proper function, it stands a better chance as the right anti-Gettier condition on knowledge.

Alvin Plantinga’s Warrant and Proper Function gives two major definitions of warrant. One states that reliable cognitive faculties aimed at true belief and functioning properly in the right environment are necessary and sufficient for warrant; the other definition only states that they are necessary. The latter definition is the more important one. There are different kinds of knowledge, and justification is necessary for some beliefs to be warranted. Even a belief warranted by proper function can receive a higher (...) degree of warrant by justification. This implies that natural theology has a useful role within the contours of a Plantingian epistemology. (Please note that the pagination here does not match the pagination in the published edition.).

"Modern History" versions of the etiological theory claim that in order for a trait X to have the proper function F, individuals with X must have been recently favored by natural selection for doing F (Godfrey-Smith 1994; Griffiths 1992, 1993). For many traits with prototypical proper functions, however, such recent selection may not have occurred: traits may have been maintained due to lack of variation or due to selection for other effects. I examine this flaw in Modern (...) History accounts and offer an alternative etiological theory, the Continuing Usefulness account, which appears to avoid such problems. (shrink)

The proper function of the heart is pumping the blood. According to what we call the type etiological view, this is because previous tokens of the type HEART were selected for pumping the blood. Nanay :412–431, 2010) argues that the type etiological view is viciously circular. He claims that the only plausible accounts of trait type individuation use proper functions, such that whenever the type etiological view is supplemented with a plausible account of trait type individuation, the (...) result is a view that uses proper functions to explain proper functions. We refine this objection, and argue that Nanay at most establishes a potentially benign definitional circularity. However, we show that the type etiological view’s reliance on types nevertheless generates a vicious regress. Hence the type etiological view is false. We reject dispositional and modal alternatives to the type etiological view for the reason that they either cannot accommodate malfunction, or do so at the cost of proliferation; and then formulate a novel token etiological view that overcomes both problems because it makes no reference to trait types.

A common line of thought in contemporary metaethics is that certain facts about the evolutionary history of humans make moral realism implausible. Two of the most developed evolutionary cases against realism are found in the works of Richard Joyce and Sharon Street. In what follows, I argue that a form of moral realism that I call proper-function moral realism can meet Joyce and Street's challenges. I begin by sketching the basics of proper-function moral realism. I then present what (...) I take to be the essence of Street's and Joyce's objections, and I show how proper-function realism answers them. (shrink)

Among psychiatric conditions, delusions have received significant attention in the philosophical literature. This is partly due to the fact that many delusions are bizarre, and their contents interesting in and of themselves. But the disproportionate attention is also due to the notion that by studying what happens when perception, cognition, and belief go wrong, we can better understand what happens when these go right. In this paper, I attend to delusions for the second reason—by evaluating the epistemology of delusions, we (...) can better understand the epistemology of ordinary belief. More specifically, given recent advancements in our understanding of how delusions are formed, the epistemology of delusions motivates a proper functionalist account of the justification of belief. Proper functionalist accounts of the justification of belief hold that whether a belief is justified is partly determined by whether the system that produces the belief is functioning properly. Whatever pathology is responsible for delusion formation, restoring it to its proper function resolves the epistemic condition, an effect which motivates proper functionalism. (shrink)
