Functions

Philosophers of biology usually distinguish historical and systemic accounts of functions. In many areas of experimental biology the "systemic" account is often the most relevant. Yet there are problems this account does admittedly not face up to very well. My contention is that, though two minor problems are irredeemably unsolvable for the systemic account of function, the major ones can be solved by assuming that 'function' denotes (directly) a causal role in a model and (indirectly) the corresponding process in nature. (...) I try to show this through the analysis of the hypothalamus-pituitary-adrenal axis of stress. (shrink)

We propose a definition of capability as a class intermediate between function and disposition as the latter are defined in Basic Formal Ontology (BFO). A disposition inheres in a material entity and is realized in a certain kind of process. An example is the disposition of a glass to break when struck, which is realized when it shatters. A function is a disposition which is (simply put) the rationale for the existence of its bearer. To say for example that a (...) water pump has the function to pump water is to say that the pump exists because something was needed that would pump water. Capabilities are a special sort of disposition in that that, like functions, they can be evaluated on the basis of how well they are realized. They differ from functions in that their realizations are not the rationale – not the primary reason – for the existence of their bearers. Thus, a water pump may have many capabilities, including to be weatherproof, to run without lubricant, and so forth, but only one function. All functions are capabilities on the view we defend, but not all capabilities are functions. We develop a series of axioms to distinguish capabilities formally from both dispositions and functions and provide examples of the use of ‘capability’ in a variety of domains. (shrink)

In her book “Are Mental Disorders Brain Disorders?” (2022), Anneli Jefferson proposes that brain processes that always realize mental dysfunctions are brain dysfunctions. This paper explores possible interpretations of two underdeveloped aspects of this thesis. First, it argues that “realization” should be interpreted as partial rather than full realization. Second, it argues that the “always” should only quantify over biologically normal situations. Taken together, these changes can account for the fact that some psychological dysfunctions are partially realized by functional mechanisms, (...) for the existence of psychological dysfunctions due to mismatches rather than brain dysfunctions, and for the fact that brain dysfunctions do not cease to be brain dysfunctions just because they can be compensated.

Teleosemantic theories aim to naturalize mental representation through the use of functions, typically based on past selection processes. However, the historical dependence of these theories has faced severe criticism, leading some philosophers to develop ahistorical alternatives. -/- This paper presents a new dilemma for all ahistorical teleosemantic theories, focusing in particular on the theories proposed by Timothy Schroeder and Bence Nanay. These theories require certain dispositions in the producers or consumers of mental representations. But the appeal to dispositions puts the (...) proponents in an undesirable position: mental content is either overly dependent on current circumstances or ultimately dependent on historical factors.

Cancer biology features the ascription of normal functions to parts of cancers. At least some ascriptions of function in cancer biology track local normality of parts within the global abnormality of the aberration to which those parts belong. That is, cancer biologists identify as functions activities that, in some sense, parts of cancers are supposed to perform, despite cancers themselves having no purpose. The present paper provides a theory to accommodate these normal function ascriptions—I call it the Modeling Account of (...) Normal Function (MA). MA comprises two claims. First, normal functions are activities whose performance by the function-bearing part contributes to the self-maintenance of the whole system and, thereby, results in the continued presence of that part. Second, MA holds that models of system-level activities that are (partly) constitutive of self-maintenance are improved by including a representation of the relevant function-bearing part and by making reference to the activity/activities that part performs which contribute(s) to those system-level activities. I contrast MA with two other accounts that seek to explicate the ascription of normal functions in biology, namely, the organizational account and the selected effects account. Both struggle to extend to cancer biology. However, I offer ecumenical readings which allow them to recover some ascriptions of normal function to parts of cancers. So, though I contend that MA excels in this respect, the purpose of this paper is served if it provides materials for bridging the gap between cancer biology, philosophy of cancer, and the literature on function.

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)

The culturally pervasive tendency to identify aspects of the body as aesthetically imperfect harms individuals and scaffolds injustice related to disability, race, gender, LGBTQ+ identities, and fatness. But abandoning the notion of imperfection may not respect people’s reasonable understandings of their own bodies. I examine the prospects for a practice of aesthetic assessment grounded in a notion of the body’s function. I argue that functional aesthetic assessment, to be respectful, requires understanding the body’s functions as complex, malleable, and determined by (...) the projects and interests of the person whose body it is. Aesthetically relevant functions, on this account, are determined neither by the body’s status as organism nor by cultural assumptions about how bodies should function or be used. (shrink)

According to recent work in experimental philosophy, folk intuitions concerning various metaphysical issues are heavily teleological. The experiments in question, which belong to a broader research program in psychology about ‘promiscuous teleology’, have featured prominently in debates about the methodology of metaphysics, with some authors claiming that the folk’s teleological bias debunks everyday intuitions concerning composition, persistence, and organisms. The present paper argues for a possibility that is very rarely discussed in that debate, namely the idea that the folk’s intuitions (...) could be veridical. Our argument is based on an emerging naturalistic theory of biological functions called “the organismic view”. The gist of the organismic view is that biological systems are characterized by a special circular causal regime where each part of the system contributes to the boundary conditions of some other parts, as well as of the whole. We argue that teleological folk intuitions are veridical in the biological domain under such a view, and they are veridical in the social and artefactual domains under coherent extensions of the organismic view.

The Uniform Determination of Death Act (UDDA) provides that “an individual who has sustained either (1) irreversible cessation of circulatory and respiratory functions or (2) irreversible cessation of all functions of the entire brain, including the brain stem, is dead.” We show that the UDDA contains two conflicting interpretations of the phrase “cessation of functions.” By one interpretation, what matters for the determination of death is the cessation of spontaneous functions only, regardless of their generation by artificial means. By the (...) other, what matters is the cessation of both spontaneous and artificially supported functions. Because each UDDA criterion uses a different interpretation, the law is conceptually inconsistent. A single consistent interpretation would lead to the conclusion that conscious individuals whose respiratory and circulatory functions are artificially supported are actually dead, or that individuals whose brain is entirely and irreversibly destroyed may be alive. We explore solutions to mitigate the inconsistency. (shrink)

Disputes about the causal structure of natural selection have implications for teleosemantics. Etiological, mainstream teleosemantics is based on a causalist view of natural selection. The core of its solution to Brentano’s Problem lies in the solution to Kant’s Puzzle provided by the Modern Synthesis concerning populational causation. In this paper, I suggest that if we adopt an alternative, statisticalist view on natural selection, the door is open for two reflections. First, it allows for setting different challenges to etiological teleosemantics that (...) arise if a statisticalist reading of natural selection is right. Second, by providing a different solution to Kant’s Puzzle based on individual causes of evolution, statisticalism promotes a different answer to Brentano’s Problem, what I label as Agential Teleosemantics.

We begin at the beginning, with an outline of Aristotle’s views on ontology and with a discussion of the influence of these views on Linnaeus. We move from there to consider the data standardization initiatives launched in the 19th century, and then turn to investigate how the idea of computational ontologies developed in the AI and knowledge representation communities in the closing decades of the 20th century. We show how aspects of this idea, particularly those relating to the use of (...) the term 'concept' in ontology development, influenced SNOMED CT and other medical terminologies. Against this background we then show how the Foundational Model of Anatomy, the Gene Ontology, Basic Formal Ontology and other OBO Foundry ontologies came into existence and discuss their role in the development of contemporary biomedical informatics.

The theoretical biology movement originating in Britain in the early 1930’s and the biosemiotics movement which took off in Europe in the 1980’s have much in common. They are both committed to replacing the neo-Darwinian synthesis, and they have both invoked theories of signs to this end. Yet, while there has been some mutual appreciation and influence, particularly in the cases of Howard Pattee, René Thom, Kalevi Kull, Anton Markoš and Stuart Kauffman, for the most part, these movements have developed (...) independently of each other. Focussing on morphogenesis understood as vegetative semiosis, in this paper I will argue that the ideas of these movements are commensurate. Furthermore, synthesising them would enable us to see life processes as proto-narratives. Doing so will involve synthesising biohermeneutics, Peircian biosemiotics with Waddington’s theoretical biology and Piagetian genetic structuralism, and this, I claim, would strengthen the challenge of these traditions to mainstream biology. At the same time, this should contribute to overcoming the opposition between the sciences and the humanities, developing a broader tradition of Schellingian thought which involves developing the humanities and then demanding of the physical and biological sciences that they are consistent with and can make intelligible the emergence of humans as conceived by the humanities.

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.

Do essence-based accounts of necessity and Vetter’s potentiality-based account of possibility in fact lead to the same result, viz., a single derived notion of necessity that is interdefinable with possibility or vice versa? And does each approach independently have the ability to reach its desired goal without having to rely on the primitive notion utilized by the other? In this essay, I investigate these questions and Vetter’s responses to them. Contrary to the “separatist” position defended by Vetter, I argue that (...) there are reasons to favor “Combination”, according to which an essence-based account of necessity should be combined with a potentiality-based account of possibility, or vice versa. According to this alternative approach, essentialism and potentialism should be regarded as allies, rather than as competitors, in a theory of derived modality, since both notions are needed in order to give a full account of necessity and possibility. Keywords: possibility, necessity, potentiality, essence, interdefinability, actuality, dependence, artifact-functions. (shrink)

50 years after its introduction, brain death remains controversial among scholars. The debates focus on one question: is brain death a good criterion for determining death? This question has been answered from various perspectives: medical, metaphysical, ethical, and legal or political. Most authors either defend the criterion as it is, propose some minor or major revisions, or advocate abandoning it and finding better solutions to the problems that brain death was intended to solve when it was introduced. Here I plead (...) for a different approach that has been overlooked in the literature: the philosophy of science approach. Some scholars claim that human death is a matter of fact, a biological phenomenon whose occurrence can be determined empirically, based on science. We should take this claim seriously, whether we agree with it or not. The question is: how do we know that human death is a scientific matter of fact? Taking the philosophy of science approach means, among other things, examining how the determination of human death became an object of scientific inquiry, exploring the nature of the brain death criterion itself, and analysing the meaning of its core concepts such as “irreversibility” and “functions”.

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. -/- .

The goal of this essay is to assess the Selected-Effects Etiological Theory of biological function, according to which a trait has a function F if and only if it has been selected for F. First, I argue that this approach should be understood as describing the paradigm case of functions, rather than as establishing necessary and sufficient conditions for function possession. I contend that, interpreted in this way, the selected-effects approach can explain two central properties of functions and can satisfactorily (...) address some recent counterexamples. This reading, however, shows that there is only a partial overlap between biological functions and selected effects, so the former cannot be reduced to the latter. Finally, I maintain that this result is still compatible with a naturalistic theory of function that appeals to some evolutionary process. (shrink)

The goal of this essay is to put forward an original theory of artifact function, which takes on board the results of the debate on the notion of biological function and also accommodates the distinctive aspects of artifacts. More precisely, the paper develops and defends the Dual-Aspect Theory, which is a monist account according to which an artifact’s function depends on intentional and reproductive aspects. It is argued that this approach meets a set of theoretical and meta-theoretical desiderata and is (...) superior to alternative views. (shrink)

Recent research on bacteria and other microorganisms has provided interesting insights into the nature of life, cooperation, evolution, individuality or species. In this paper, I focus on the capacity of bacteria to produce molecules that are usually classified as ’signals’ and I defend two claims. First, I argue that certain interactions between bacteria should actually qualify as genuine forms of communication. Second, I use this case study to revise our general theories of signaling. Among other things, I argue that a (...) plausible requirement for a state to qualify as a signal is that it is a minimal cause. (shrink)

Teleology has a complicated history in the biological sciences. Some have argued that Darwin’s theory has allowed biology to purge itself of teleological explanations. Others have been content to retain teleology and to treat it as metaphorical, or have sought to replace it with less problematic notions like teleonomy. And still others have tried to naturalize it in a way that distances it from the vitalism of the nineteenth century, focusing on the role that function plays in teleological explanation. No (...) consensus has seemed possible in this debate. This paper takes a different approach. It argues that teleology is a perfectly acceptable scientific notion, but that the debate took an unfortunate misstep some 2300 years ago, one that has confused things ever since. The misstep comes in the beginning of Aristotle’s Physics when a distinction is made between two types of teleological explanation. One type pertains to artifacts while the other pertains to entities in nature. For Aristotle, artifacts are guided by something external to themselves, human intentions, while natural entities are guided by an internal nature. We aim to show that there is, in fact, only one type of legitimate teleological explanation, what Aristotle would have considered a variant of an artifact model, where entities are guided by external fields. We begin with an analysis of the differences between the two types of explanation. We then examine some evidence in Aristotle’s biological works suggesting that on account of his natural-artifactual distinction, he encountered difficulties in trying to provide teleological accounts of spontaneous generation. And we show that it is possible to resolve these difficulties with a more robust version of an artifact model of teleology, in other words, with an externalist teleology. This is McShea’s model, in which goal-directed entities are guided by a nested series of upper-level fields. To explain teleological behavior, this account invokes only external physical forces rather than mysterious internal natures. We then consider how field theory differs from other efforts to naturalize teleology in biology. And finally, we show how the account enables us to grapple with certain difficult cases – genes and intentions – where, even in biology today, the temptation to posit internal natures remains strong.

The new mechanists and the autonomy approach both aim to account for how biological phenomena are explained. One identifies appeals to how components of a mechanism are organized so that their activities produce a phenomenon. The other directs attention towards the whole organism and focuses on how it achieves self-maintenance. This paper discusses challenges each confronts and how each could benefit from collaboration with the other: the new mechanistic framework can gain by taking into account what happens outside individual mechanisms, (...) while the autonomy approach can ground itself in biological research into how the actual components constituting an autonomous system interact and contribute in different ways to realize and maintain the system. To press the case that these two traditions should be constructively integrated we describe how three recent developments in the autonomy tradition together provide a bridge between the two traditions: (1) a framework of work and constraints, (2) a conception of function grounded in the organization of an autonomous system, and (3) a focus on control.

According to Karen Neander’s causal-informational teleosemantics, the contents of perceptual states depend on the etiological response functions of sensory-perceptual systems. In this paper, I argue that this theory is, despite its virtues, unable to explain how humans and other animals are capable of perceiving properties with which no sensory-perceptual system has ever been confronted. After rejecting Neander’s own proposal in terms of second-order similarity and a proposal inspired by Ruth Millikan in terms of simplicity, I offer a solution which equates (...) functions with manifestations of dispositions that made a difference to evolutionary success. My suggestion is able to generate determinate and plausible contents for new perceptual states while still preserving the idea that etiological functions explain evolutionary success. (shrink)

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)

I introduce functional powers, i.e., causal powers that play the role of functions. In the first section, I characterize functions and present some desiderata for a good theory of functions. In the second section, I make some assumptions about the ontology of powers, teleology and structures-that will be helpful in order to ground my account of functional powers. In the third section, sixteen different types of functional powers are examined. All such types of functional powers will exhaustively contribute to performing (...) all the ontological and explanatory tasks that may be attributed to functions. Finally, in the fourth section, it is shown how my account of functions as functional powers satisfies all the desiderata presented at the outset. (shrink)

1. IntroductionIn What Biological Functions Are and Why They Matter, Justin Garson offers a novel theory of biological functions, the generalized selected effects (GSE) theory.1 He presents the theory in a clear and comprehensive way, defends it against various objections and applies it to different areas of philosophy, including the philosophy of psychiatry, the debate about mechanisms and the debate about teleosemantic theories of mental content.2Like other proponents of the aetiological approach to functions, Garson maintains that a trait’s biological functions (...) are grounded in its selectional history. However, his GSE theory differs from standard versions of the aetiological approach – so-called selected effects (SE) theories – in a crucial respect: while SE theories assume that all biological functions must ultimately be grounded in phylogenetic processes of natural selection or other (closely analogous) processes of differential reproduction (Millikan 1984: 15–82, Neander 1991, Godfrey-Smith 1994), the GSE theory allows that functions may also be grounded in processes of differential retention (see §2 for details). Garson forcefully argues that this broader account is theoretically well-motivated and has significant advantages over standard SE accounts when it comes to accommodating certain important classes of ontogenetically determined functions.

A proper function of an entity is a beneficial effect that helps explain the persistence of the entity. Proper functions thereby arise through feedback mechanisms with beneficial effects as inputs and persistence as outputs. We continue to make assertions because they benefit speakers by benefiting speakers. Hearers benefit from true information. Speakers benefit by influencing hearer belief. If hearers do not benefit, they will not form beliefs in response to assertions. Speakers can then only maintain influence by providing true information, (...) often enough. The function of assertion is then inducing true hearer belief. When interests conflict, however, some mechanism must ensure that speakers provide true information often enough, instead of deceiving, or providing information regardless of quality. In humans, a core mechanism stabilizing true assertion involves social norms for truth telling. We tell the truth partly because we prescribe and enforce telling the truth. (shrink)

I examine the use of the term function in Aldo Leopold’s land ethic, invoked as (1) the healthy functioning of the land community, which is dependent on (2) the maintenance of the characteristic functions of populations that are parts of the land community. The latter can be understood as referring to interactions between species that are the products of coevolution (such as parasite-host, predator-prey) and, thus, in terms of the “selected effect” account of function. The performance of these functions under (...) certain conditions maintain what Leopold took to be the healthy functioning of a land community. (shrink)

How questions and why questions interact in complex ways within biological practice. One of the most fruitful accounts to think about this relation is the widely known systemic approach, which has its origin mainly in the works of Robert Cummins (1975, 1983). As we will show, this approach effectively manages to capture much of what biologists do, especially in areas such as molecular biology, neuroscience and neuroethology. Our aim with this work is to discuss the metatheoretical status of the presuppositions (...) behind systemic analysis. We will hold that these assumptions are of an empirical nature, and that they can be reconstructed as parts of a theory. (shrink)

This paper investigates the concept of behavioral autonomy in Artificial Life by drawing a parallel to the use of teleological notions in the study of biological life. Contrary to one of the leading assumptions in Artificial Life research, I argue that there is a significant difference in how autonomous behavior is understood in artificial and biological life forms: the former is underlain by human goals in a way that the latter is not. While behavioral traits can be explained in relation (...) to evolutionary history in biological organisms, in synthetic life forms behavior depends on a design driven by a research agenda, further shaped by broader human goals. This point will be illustrated with a case study on a synthetic life form. Consequently, the putative epistemic benefit of reaching a better understanding of behavioral autonomy in biological organisms by synthesizing artificial life forms is subject to doubt: the autonomy observed in such artificial organisms may be a mere projection of human agency. Further questions arise in relation to the need to spell out the relevant human aims when addressing potential social or ethical implications of synthesizing artificial life forms. (shrink)

Why would philosophers interested in the points or functions of our conceptual practices bother with genealogical explanations if they can focus directly on paradigmatic examples of the practices we now have?? To answer this question, I compare the method of pragmatic genealogy advocated by Edward Craig, Bernard Williams, and Miranda Fricker—a method whose singular combination of fictionalising and historicising has met with suspicion—with the simpler method of paradigm-based explanation. Fricker herself has recently moved towards paradigm-based explanation, arguing that it is (...) a more perspicuous way of reaping the same explanatory pay-off as pragmatic genealogy while dispensing with its fictionalising and historicising. My aim is to determine when and why the reverse movement from paradigm-based explanation to pragmatic genealogy remains warranted. I argue that the fictionalising and historicising of pragmatic genealogy is well motivated, and I outline three ways in which the method earns its keep: by successfully handling historically inflected practices which paradigm-based explanation cannot handle; by revealing and arguing for connections to generic needs we might otherwise miss; and by providing comprehensive views of practices that place and relate the respects in which they serve both generic and local needs.

We will survey a range of ontologies relevant to space and ground system domains. The ontologies form part of the Common Core Ontology ecosystem (CCO) developed under the IARPA KDD initiative. We focus specifically on the Space Domain Ontologies, a suite of ontologies to support space situational awareness, including the Spacecraft Mission Ontology, Spacecraft Ontology, Space Event Ontology and Space Object Ontology.

In this paper, I argue that what counts as the proper function of a trait is a matter of the de facto perspective that the biological system, itself, possesses on what counts as proper functioning for that trait. Unlike non-perspectival accounts, internal perspectivalism does not succumb to generality problems. But unlike external perspectivalism, internal perspectivalism can provide a fully naturalistic, mind-independent grounding of proper function and natural norms. The attribution of perspectives to biological systems is intended to be neither metaphorical (...) nor anthropomorphic: I do not mean to imply that such systems thereby must possess agency, cognition, intentions, concepts, or mental or psychological states. Instead, such systems provide the grounding for norms of performance when they internally enforce their own standard of (i.e., their own perspective on) what constitutes proper functioning or malfunctioning. By operating with a fixed, determinate level of generality, such systems provide the basis for an account of proper function that is immune to generality problems. (shrink)

I analyze a tension at the core of the mechanistic view of computation generated by its joint commitment to the medium independence of computational vehicles and to computational systems possessing teleological functions to compute. While computation is individuated in medium-independent terms, teleology is sensitive to the constitutive physical properties of vehicles. This tension spells trouble for the mechanistic view, suggesting that there can be no teleological functions to compute. I argue that, once considerations about the relevant function-bestowing factors for computational (...) systems are brought to bear, the tension dissolves: physical systems can have the teleological function to compute.

This paper aims to provide a philosophical and theoretical account of biological communication grounded in the notion of organisation. The organisational approach characterises living systems as organised in such a way that they are capable to self-produce and self-maintain while in constant interaction with the environment. To apply this theoretical framework to the study of biological communication, we focus on a specific approach, based on the notion of influence, according to which communication takes place when a signal emitted by a (...) sender triggers a change in the behaviour of the receiver that is functional for the sender itself. We critically analyse the current formulations of this account, that interpret what is functional for the sender in terms of evolutionary adaptations. Specifically, the adoption of this etiological functional framework may lead to the exclusion of several phenomena usually studied as instances of communication, and possibly even of entire fields of investigation such as synthetic biology. As an alternative, we reframe the influence approach in organisational terms, characterising functions in terms of contributions to the current organisation of a biological system. We develop a theoretical account of biological communication in which communicative functions are distinguished from other types of biological functions described by the organisational account (e.g. metabolic, ecological, etc.). The resulting organisational-influence approach allows to carry out causal analyses of current instances of phenomena of communication, without the need to provide etiological explanations. In such a way it makes it possible to understand in terms of communication those phenomena which realise interactive patterns typical of signalling interactions – and are usually studied as such in scientific practice – despite not being the result of evolutionary adaptations. Moreover, this approach provides operational tools to design and study communicative interactions in experimental fields such as synthetic biology. (shrink)

In this journal, Schulte develops a novel solution to the problem of distal content: by virtue of what is a mental representation about a distal object rather than a more proximal cause of that representation? Schulte maintains that in order for a representation to have a distal content, it must be produced by a constancy mechanism, along with two other conditions. I raise three objections to his solution. First, a core component of Schulte's solution is just a restrictive version of (...) Dretske's solution, but Schulte gives no argument for his restriction. Second, his proposed solution to a disjunction problem is ad hoc. Finally, his ‘far-out’ version of the distality problem is not a version of the distality problem at all. I conclude that Dretske's solution is preferable to Schulte's. (shrink)

Mainstream teleosemantics is the view that mental representation should be understood in terms of biological functions, which, in turn, should be understood in terms of selection processes. One of the traditional criticisms of teleosemantics is the problem of novel contents: how can teleosemantics explain our ability to represent properties that are evolutionarily novel? In response, some have argued that by generalizing the notion of a selection process to include phenomena such as operant conditioning, and the neural selection that underlies it, (...) we can resolve this problem. Here, we do four things: we develop this suggestion in a rigorous way through a simple example, we draw on recent neurobiological research to support its empirical plausibility, we defend the move from a host of objections in the literature, and we sketch how the picture can be extended to help us think about more complex “conceptual” representations and not just perceptual ones.

Having an etiological function to F is sufficient to have a competence to F. Having an etiological function to reliably F is sufficient to have a reliable competence, a competence to reliably F. Epistemic warrant consists in the normal functioning of the belief-forming process when the process has forming true beliefs reliably as an etiological function. Epistemic warrant requires reliable competence. Warrant divides into two grades. The first consists in normal functioning, when the process has forming true beliefs reliably as (...) an etiological function, so that it reliably produces true beliefs when in normal conditions, but need not be in normal conditions. The second grade requires the first, and presence in normal conditions, so that the chance of true belief is high. Why is warrant normative? Because when reliably forming true beliefs is a function, both grades meet evaluative norms that follow from that function. The paper ends by comparing Tyler Burge’s answer to this question from "Perceptual Entitlement" and "Entitlement: The Basis of Empirical Warrant". It is argued that Burge’s answer implausibly presupposes that all belief-forming processes—not just those with forming reliably true beliefs as an etiological function—should form reliably true beliefs.

Today's science tells us that our bodies are filled with molecular machinery that orchestrates all sorts of life processes. When we think, microscopic "channels" open and close in our brain cell membranes; when we run, tiny "motors" spin in our muscle cell membranes; and when we see, light operates "molecular switches" in our eyes and nerves. A molecular-mechanical vision of life has become commonplace in both the halls of philosophy and the offices of drug companies, where researchers are developing “proton (...) pump inhibitors” or medicines similar to Prozac. Membranes to Molecular Machines explores just how late twentieth-century science came to think of our cells and bodies this way. This story is told through the lens of membrane research, an unwritten history at the crossroads of molecular biology, biochemistry, physiology, and the neurosciences, that directly feeds into today's synthetic biology as well as nano- and biotechnology. Mathias Grote shows how these sciences not only have made us think differently about life, they have, by reworking what membranes and proteins represent in laboratories, allowed us to manipulate life as "active matter" in new ways. Covering the science of biological membranes in the United States and Europe from the mid-1960s to the 1990s, this book connects that history to contemporary work with optogenetics, a method for stimulating individual neurons using light, and will enlighten and provoke anyone interested in the intersection of chemical research and the life sciences—from practitioner to historian to philosopher.

Evolutionary psychology tends to be associated with a massively modular cognitive architecture. On this framework of human cognition, an assembly of specialized information processors called modules developed under selection pressures encountered throughout the phylogenic history of hominids. The coordinated activity of domain-specific modules carries out all the processes of belief fixation, abstract reasoning, and other facets of central cognition. Against the massive modularity thesis, I defend an account of systemic functional adaptedness, according to which non-modular systems emerged because of adaptive (...) problems imposed by the intrinsic physiology of the evolving human brain. The proposed reformulation of evolutionary theorizing draws from neural network models and Cummins’ (1975) account of systemic functions to identify selection pressures that gave rise to non-modular, domain-general mechanisms in cognitive architecture.

Functional diversity holds the promise of understanding ecosystems in ways unattainable by taxonomic diversity studies. Underlying this promise is the intuition that investigating the diversity of what organisms actually do—i.e. their functional traits—within ecosystems will generate more reliable insights into the ways these ecosystems behave, compared to considering only species diversity. But this promise also rests on several conceptual and methodological—i.e. epistemic—assumptions that cut across various theories and domains of ecology. These assumptions should be clearly addressed, notably for the sake (...) of an effective comparison and integration across domains, and for assessing whether or not to use functional diversity approaches for developing ecological management strategies. The objective of this contribution is to identify and critically analyze the most salient of these assumptions. To this aim, we provide an “epistemic roadmap” that pinpoints these assumptions along a set of historical, conceptual, empirical, theoretical, and normative dimensions. (shrink)

The etiological account of function defines a part’s/trait’s function as whatever that part/trait does and was selected for doing. Some philosophers have tried to employ this as an account of biological interests, claiming that to benefit an organism is to promote its etiological functioning and to harm it is to inhibit such functioning. I argue that etiological functioning is not a good account of biological interests. I first describe the history of theories of biological interests, explaining the special role that (...) etiological accounts of function have played within such theories. Second, I explain the problems with allowing etiological accounts of function to play this role and consider objections to my line of argument. Finally, I consider the theoretical alternatives to etiological function accounts of interests and assess their advantages and disadvantages. (shrink)

We provide a new perspective on the relation between the space of description of an object and the appearance of novelties. One of the aims of this perspective is to facilitate the interaction between mathematics and historical sciences. The definition of novelties is paradoxical: if one can define in advance the possibles, then they are not genuinely new. By analyzing the situation in set theory, we show that defining generic (i.e., shared) and specific (i.e., individual) properties of elements of a (...) set are radically different notions. As a result, generic and specific definitions of possibilities cannot be conflated. We argue that genuinely stating possibilities requires that their meaning has to be made explicit. For example, in physics, properties playing theoretical roles are generic; then, generic reasoning is sufficient to define possibilities. By contrast, in music, we argue that specific properties matter, and generic definitions become insufficient. Then, the notion of new possibilities becomes relevant and irreducible. In biology, among other examples, the generic definition of the space of DNA sequences is insufficient to state phenotypic possibilities even if we assume complete genetic determinism. The generic properties of this space are relevant for sequencing or DNA duplication, but they are inadequate to understand phenotypes. We develop a strong concept of biological novelties which justifies the notion of new possibilities and is more robust than the notion of changing description spaces. These biological novelties are not generic outcomes from an initial situation. They are specific and this specificity is associated with biological functions, that is to say, with a specific causal structure. Thus, we think that in contrast with physics, the concept of new possibilities is necessary for biology. (shrink)

This paper examines Miranda Fricker’s method of paradigm-based explanation and in particular its promise of yielding an ordered pluralism. Fricker’s starting point is a schism between two conceptions of forgiveness, Moral Justice Forgiveness and Gifted Forgiveness. In the light of a hypothesis about the basic point of forgiveness, she reveals the unity underlying the initially baffling plurality and brings order into it, presenting a paradigmatic form of forgiveness as explanatorily basic and other forms as derivative. The resulting picture, she claims, (...) is an ‘explanatorily satisfying ordered pluralism.’ But what is this ordered pluralism and how does Fricker’s method deliver it? And to what extent can this strategy be generalised to other conceptual practices? By making explicit and critically examining the conception of ordered pluralism implicit in Fricker’s procedure, I assess the promise that her approach holds as a way of resolving stand-offs between warring conceptions of ideas or practices more widely. I argue that it holds great promise in this respect, but that if we are to avoid reproducing just the schismatic debates that the pluralism of paradigm-based explanation is supposed to overcome at the level of what is to be regarded as a paradigm case, we need to take seriously the thought that what counts as a paradigm is partly determined by our purposes in giving a paradigm-based explanation.

We introduce a new type of pluralism about biological function that, in contrast to existing, demonstrates a practical integration among the term’s different meanings. In particular, we show how to generalize Sandra Mitchell’s notion of integrative pluralism to circumstances where multiple epistemic tools of the same type are jointly necessary to solve scientific problems. We argue that the multiple definitions of biological function operate jointly in this way based on how biologists explain the evolution of protein function. To clarify how (...) our account relates to existing views, we introduce a general typology for monist and pluralist accounts along with standardized criteria for judging which is best supported by evidence.

Deception has recently received a significant amount of attention. One of main reasons is that it lies at the intersection of various areas of research, such as the evolution of cooperation, animal communication, ethics or epistemology. This essay focuses on the biological approach to deception and argues that standard definitions put forward by most biologists and philosophers are inadequate. We provide a functional account of deception which solves the problems of extant accounts in virtue of two characteristics: deceptive states have (...) the function of causing a misinformative states and they do not necessarily provide direct benefits to the deceivers and losses to the targets.

Bence Nanay has argued that we must abandon the etiological theory of teleological function because this theory explains functions and functional categories in a circular manner. Paul Griffiths argued earlier that we should retain the etiological theory and instead prevent the circularity by making etiologies independent of functional categories. Karen Neander and Alex Rosenberg reply to Nanay similarly, and argue that we should analyze functions in terms of natural selection acting not on functional categories, but merely on lineages. Nanay replies (...) that these lineages cannot be individuated except by reference to functional categories. Worryingly, Neander and Rosenberg themselves have previously argued persuasively that homology often depends on function. This article addresses their arguments and shows how to escape them: Regardless whether the arguments are right about long-term homological categories, they do not apply to generation-to-generation homology. The latter, moreover, is sufficient for individuating the lineages needed to explain teleological functions. (shrink)

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

I distinguish two forms of pluralism about biological functions, between-discipline pluralism and within-discipline pluralism. Between-discipline pluralism holds that different theories of function are appropriate for different subdisciplines of biology and psychology. I provide reasons for rejecting this view. Instead, I recommend within-discipline pluralism, which emphasizes the plurality of function concepts at play within any given subdiscipline of biology and psychology.
