Teleology and Function

This paper presents a novel theory of artifact functions, drawing from persistence-based accounts of social functions, according to which the function of an artifact consists in those of its effects that contribute to the persistence of its kind. First, the paper argues that artifact functions have an underacknowledged “interventionist task”: functional ascriptions have implications for the ways that users have reason to use technologies, and how they have reason to intervene when technologies have undesired effects. Then, it argues that the (...) ways that users have reason to use technologies and intervene are informed by the present persistence conditions of artifact kinds. It is therefore useful to incorporate these persistence conditions into the artifacts’ functions. By focusing on the social and political embedding of artifacts, the theory also allows for fruitful connections between the theory of artifacts, the political philosophy of technology, and the literature on functions in the philosophy of social science.

Synthetic biology (SynBio) covers two main areas: application engineering, exemplified by metabolic engi- neering, and the design of life from artificial building blocks. As the general public is often reluctant to embrace synthetic approaches, preferring nature to artifice, its immediate future will depend very much on the public’s reaction to the unmet needs created by the pervasive demands of sustainability. On the other hand, this reluctance should not have a negative impact on research that will now take into account the (...) existence of the multiple transitions that cells face over time. The ages of life—birth, development, maturation, senescence and death—reflect specific key transitions and have, until now, rarely been taken into account in SynBio designs. This results in a mismatch between novelty and the very long evolutionary time that led to the existing chassis [remember that this is the common term used to describe the cellular framework as seen by synthetic biologists (de Lorenzo & Danchin, 2008)]. It also implies that, in general, transitions between growth stages will be taken into account with the appro- priate embodiment of highly specific processes. This is particularly important when adapting new models to their host, whether natural or artificial. Adaptation fol- lows two stages, short-term accommodation of new entities and long-term assimilation into the cell as a whole. This requires discrimination between classes of entities. We suggest that proteins playing the essential role of Maxwell’ demons, here named Maxwell’s dis- criminators (MxDs) to refer to their original function, will permit the assimilation and accommodation of artificial constructs. As a consequence, we can foresee that class discrimination, beyond mere recognition, will be implemented in SynBio 2.0, leading to an authentic par- adigm shift (Kuhn, 1996), based on conceptions that embody information as a genuine currency of reality.

Agency is a central concept in the organisational approach to organisms, which accounts for their internal purposiveness. Recent recognition of the active role played by organisms in evolution has led researchers to use this concept in an evolutionary approach. Agency is then considered in terms of ‘unintentional’ choice: agents choose from a given repertoire the behaviour most appropriate to their goal, with this choice influencing evolutionary pathways. This view, while allowing for the evolutionary role of the activity of organisms, presents (...) two pitfalls. First, it restricts organisms’ agency by confining their choice within the bounds of a behavioural repertoire, and assuming their goals are dictated by natural selection. Second, this view, while claiming to eliminate the idea of intentionality, retains its structure: organisms are portrayed as rational entities, persistently pursuing specific goals. This leads us back to a teleological thinking, whose use in evolutionary theory has already been heavily criticised. This paper proposes a conception of biological agency which does not assume goal-directedness but considers agency as inventiveness. An organism will be said to be an agent if it is the triggering cause of behaviours falling outside the known repertoire and whose form can only be explained by the unique relationship between the organism and the environment. If these behaviours have implications in evolution, the agent will be considered an evolutionary agent. The merit of this approach is further validated by evidencing the significant role behavioural innovations play in evolution. Finally, the last section delves into the process of invention by examining animal play. (shrink)

This paper defines and defends a notion of teleological function which is fit to figure in explanations concerning how organic systems, and the items which compose them, are able to perform certain activities, such as surviving and reproducing or pumping blood. According to this notion, a teleological function of an item (such as the heart) is a typical way in which items of that type contribute to some containing system's ability to do some activity. An account of what it is (...) for an item to contribute to a containing system's ability to perform an activity is provided. I argue that the view acquires its normative status in virtue of the fact that it obeys a function-accident distinction and obeys a function-dysfunction distinction; that the view is ahistorical; and, that its ahistoricity provides it with an advantage over one of its main competitors.

Cancer biologists ascribe normal functions to parts of cancer. Normal functions are activities that parts of systems are in some minimal sense supposed to perform. Cancer biologists’ finding normality within the abnormality of cancer pose difficulties for two main approaches to normal function. One approach claims that normal functions are activities that parts are selected for. However, some parts of cancers that have normal functions aren’t selected to perform them. The other approach claims that normal functions are part-activities typical for (...) the system and that contribute to survival/reproduction. However, cancers are too heterogeneous to establish what’s typical across a type. (shrink)

Darwin diceva che le specie si trasformavano per poter sopravvivere: arriva un terremoto, un’inondazione e solo chi sa correre rapidamente o chi sa nuotare vive. Ok, ma cosa ci dice questa teoria sui cambiamenti che non portano a migliori possibilità di sopravvivere o di riprodursi? Ben poco. Perché nel corso dei secoli i denti molari dell’uomo si sono ridotti di dimensioni, così come le dita dei piedi? Certo non per sopravvivere e riprodursi meglio. Gli autori riportano nel corso di questa (...) rassegna vari esempi che la teoria di Darwin non riesce a spiegare e delle possibili spiegazioni alternative, asseverate da esperimenti scientifici validati e consacrati dalla comunità scientifica. Darwin aveva torto? Certamente no! Ma come tutte le opere della scienza richiede revisioni e miglioramenti. (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)

There’s a general assumption that teleology and function do not exist in inanimate nature. Throughout biology, it is generally taken as granted that teleology (or teleonomy) and functions are not only unique to life, but perhaps even a defining quality of life. For many, it’s obvious that rocks, water, and the like, are not teleological, nor could they possibly have stand-alone functions. This idea - that teleology and function are unique to life - is the target of this paper. I (...) begin with an overview of McShea’s field theoretic account of teleology. I start with the field theoretic account because it presents a promising analysis of teleological systems. It is promising because, in not making any assumptions about life’s special status in teleological systems, it avoids counterexamples that have problematized other accounts. I then consider some of the prominent efforts that have been made to attempt to avoid ascribing functions or teleology to some form of inanimate nature. In my assessment, none of the efforts are successful. I conclude by offering mineral evolution as a case study to show how inanimate nature can be both teleological and functional. The evolution of mineral species reveals that teleology and function extend to inanimate nature, and that teleology and function come in degrees. (shrink)

An introduction to the Rond worldview, which is based on ideas from science, philosophy, and spirituality and designed to help one understand the nature of existence and cope with the human condition. With regard to philosophy: the concept of rondure is applied to aesthetics, ontology, metaphysics, cosmology, scientific phenomenology, philosophy of mind, philosophy of conduct (ethics), and epistemology.

Bergson offers an epistemological critique of Darwin’s theory that focuses on his gradualism: for Darwin variation is “minute”, and Bergson glosses “insensible.” His main argument is that if variations are insensible, they cannot confer an advantage to the organism and therefore be selected. Yet, for Darwin, the selected variation is not insensible: to be selected, it must be beneficial to its bearer in the struggle for existence. This article aims at understanding the origin of this misunderstanding by tracing the history (...) of this critique. To do this, we will study Bergson’s sources, showing that his interpretation of Darwin is in line with the critique of many biologists at the turn of the 20th century, albeit in a confused way. This will lead us back to the origin of this critique: the work of Mivart. In this study, we wish to reveal the anchor of the Bergsonian interpretation in the debates of his time, and the shifts from the traditional exposition of the argument that led Bergson to formulate this false paradox. This article will also analyze more precisely the counterexample of the “analogy of structure” to show that, despite Bergson’s misunderstanding, he did point to actual limits of the Darwinian theory.

This dissertation argues that cognition is a kind of natural agency. Natural agency is the capacity that certain systems have to act in accordance with their own norms. Natural agents are systems that bias their repertoires in response to affordances in the pursuit of their goals. -/- Cognition is a special mode of this general phenomenon. Cognitive systems are agents that have the additional capacity to actively take their worlds to be certain ways, regardless of whether the world is really (...) that way. In this way, cognitive systems are desituated. Desituatedness is the root of specifically cognitive capacities for representation and abstraction. -/- There are two main reasons why this view needs defending. First, natural agency is typically viewed as incompatible with natural science because it is committed to a teleological mode of explanation. Second, cognition is typically held to be categorically distinct from natural agency. This dissertation argues against both of these views. It argues against the incompatibility of agency and natural science by demonstrating that systems biology, general systems theory, and sciences that deal with complex systems have typically underappreciated conceptual and theoretical resources for grounding agency in the causal structure of the world. These conceptual resources do not, however, reduce agency to systems theory because the normativity inherent in agency demands descriptive resources beyond those of even the most sophisticated systems theory. It argues against the categorical difference between natural agency and cognition by pointing out that separating cognition from a richer web of situated, ecologically embedded relations between the agent and the world generates the frame problem, which is an insuperable obstacle to making cognition that is sufficiently responsive to the complexity of the world. Rooting cognition in natural agency is a more robust empirical bet for theorizing cognition and artificial intelligence. (shrink)

Our goal is to illustrate that Darwinian and autopoietic views of the organism are not as squarely opposed to each other as is often assumed. Indeed, we will argue that there is much common ground between them and that they can usefully supplement each other.

En este artículo sostenemos que, en aquellos casos en los cuales la capacidad _ explanandum _ de un análisis sistémico o mecanicista constituye una función biológica, globalmente, la función explica la estructura y no a la inversa, a pesar de que en algunos casos particulares, el orden en que se determinan los conceptos participantes en la explicación no coincide con el orden de la explicación. Para defender esta tesis, adoptaremos una concepción mínima de explicación basada en la idea de subsunción (...) ampliativa del estructuralismo e ilustraremos las diferencias entre el orden de la explicación y el orden de determinación de los conceptos mediante un estudio de caso tomado de la afasiología moderna.

Many have argued that the very notion of human nature is untenable given the facts of evolution and should accordingly be discarded. This paper, by contrast, argues that the notion can be retained in a coherent and modern way. The present account expounds on the view of human nature as a collection of species-typical psychological adaptations, and outlines how it can be understood in formally modeled computational terms. The view defended is also heavily developmental and connects directly with contemporary evolutionary (...) developmental biology. Furthermore, the notion of human nature developed here allows us to abstract away from the obfuscating variability that manifests not only between individuals across ontogeny, but also cross-culturally and throughout time.

A theoretical framework is provided to explore teleonomy as a problem of self-causation, distinct from upward, downward and reticulate causation. Causality theories in biology are often formulated within hierarchy theories, where causation is conceptualized as running up or down the rungs of a ladder-like hierarchy or, more recently, as moving between multiple hierarchies. Research on the genealogy of cosmologies demonstrates that in addition to hierarchy theories, causality theories also depend upon ideas of time. This paper explores the roots and impact (...) of both time and hierarchy thinking on causal reasoning in the evolutionary sciences. Within evolutionary biology, the Neodarwinian synthesis adheres to a linear notion of time associated with linear hierarchies that portray upward causation. Eco-evo-devo schools recognize the importance of downward causation and consequently receive resistance from the standard view because downward causation is sometimes understood as backward causation, considered impossible by adherents of a linear time model. In contrast, downward causation works with a spatial or presential time notion. Hybridization, lateral gene transfer, infective heredity, symbiosis and symbiogenesis require recognition of reticulate causation occurring in both space and time, or spacetime, between distinct and interacting ontological hierarchies. Teleonomy is distinct from these types of causation because it invokes the problem of self-causation. By asking how the focal level in a hierarchy can persist through time, self-causation raises philosophical concerns on the nature of duration, identity and individuality. (shrink)

En este trabajo presentamos los fundamentos teóricos de una propuesta para el abordaje didáctico de concepciones teleológicas de los y las estudiantes en la enseñanza de la Biología. La propuesta en cuestión supone acudir al modo en que Darwin lidió con las concepciones teleológicas dominantes entre sus contemporáneos, para proponer una estrategia general a través de la cual se podría incidir sobre las intuiciones teleológicas de los estudiantes, de modo que se pueda facilitar el aprendizaje de la teoría de la (...) selección natural. Sugeriremos también que esta propuesta implica un modo original de apelar a la analogía entre el cambio teórico en la Historia de la Ciencia y el aprendizaje de las ciencias. (shrink)

Algunos aspectos de La expresión de las emociones de Charles Darwin pueden resultar intrigantes, pues, en la explicación de cómo tales expresiones se originan, Darwin casi nunca apela a la selección natural. En cambio, apela principalmente a la idea de que movimientos voluntarios se asocian a emociones, volviéndose por hábito innatos e involuntarios al heredarse a la descendencia. Si bien Darwin da varias razones para defender esta explicación, en este trabajo trataré de mostrar que, si se entiende el libro sobre (...) las expresiones en relación con los objetivos explícitos e implícitos de El origen del hombre, el asunto se entiende mejor. En particular, resulta interesante la tesis que Desmond y Moore plantean respecto a la importancia de los ideales antiesclavistas de Darwin a la hora del tratamiento de las razas. Defenderé en este trabajo que el enfoque de Desmond y Moore puede extenderse al libro acerca de las expresiones. Específicamente, estableceré vínculos entre la explicación del origen de las razas y la explicación del origen del rubor. Palabras clave: Charles Darwin, La expresión de las emociones, El origen del hombre, Rubor, Antiesclavismo. (shrink)

The free energy principle is notoriously difficult to understand. In this paper, we relate the principle to a framework that philosophers of biology are familiar with: Ruth Millikan’s teleosemantics. We argue that: systems that minimise free energy are systems with a proper function; and Karl Friston’s notion of implicit modelling can be understood in terms of Millikan’s notion of mapping relations. Our analysis reveals some surprising formal similarities between the two frameworks, and suggests interesting lines of future research. We hope (...) this will aid further philosophical evaluation of the free energy principle. (shrink)

This paper argues that the account of teleology previously proposed by the authors is consistent with the physical determinism that is implicit across many of the sciences. We suggest that much of the current aversion to teleological thinking found in the sciences is rooted in debates that can be traced back to ancient natural science, which pitted mechanistic and deterministic theories against teleological ones. These debates saw a deterministic world as one where freedom and agency is impossible. And, because teleological (...) entities seem to be free to either reach their ends or not, it was assumed that they could not be deterministic. Mayr’s modern account of teleonomy adheres to this basic assumption. Yet, the seeming tension between teleology and determinism is illusory because freedom and agency do not, in fact, conflict with a deterministic world. To show this, we present a taxonomy of different types of freedom that we see as inherent in teleological systems. Then we show that our taxonomy of freedom, which is crucial to understanding teleology, shares many of the features of a philosophical position regarding free will that is known in the contemporary literature as ‘compatibilism’. This position maintains that an agent is free when the sources of its actions are internal, when the agent itself is the deterministic cause of those actions. Our view shows that freedom is not only indispensable to teleology, but also that, contrary to common intuitions, there is no conflict between teleology and causal determinism. (shrink)

Justin Garson has recently advanced a Generalised Selected Effects Theory of biological proper function. According to Garson, his theory spells trouble for the Dysfunction Account of Disorder. This paper argues that Garson’s critique of the Dysfunction Account from the Generalised Theory fails, and that we should reject the Generalised Theory outright. I first show that the Generalised Theory does not, as Garson asserts, imply that neurally selected disorders are not dysfunctional. Rather, it implies that they are both functional and dysfunctional. (...) I argue on this basis that the Generalised Theory yields conflicting functional norms, and we that should reject it outright on these grounds. (shrink)

The notion of biological function is fraught with difficulties—intrinsically and irremediably so, we argue. The physiological practice of functional ascription originates from a time when organisms were thought to be designed and remained largely unchanged since. In a secularized worldview, this creates a paradox which accounts of functions as selected effect attempt to resolve. This attempt, we argue, misses its target in physiology and it brings problems of its own. Instead, we propose that a better solution to the conundrum of (...) biological functions is to abandon the notion altogether, a prospect not only less daunting than it appears, but arguably the natural continuation of the naturalisation of biology.

Historically, biocentrists have ascribed interests to organisms via an account of function. One promising account of function for this purpose is the organizational or autopoietic account of function, according to which some entity x has a function of self-maintenance when the parts of x contribute to the goal of self-maintenance. In this paper, I will present the autopoietic account of interests and provide some reasons for thinking that this account is promising. I will also present a possible issue for the (...) biocentrist who uses the autopoietic account of function given the following two claims: what it means to be a biological “self” is ambiguous, and the autopoietic account of interests relies on a self boundary. I argue that the proponent of this account then needs to choose a definition of individual and explain why that definition is morally relevant. Otherwise, the proponent of the autopoietic account has not given an account of what constitutes a harm or a benefit for a biological individual, and there are good reasons to believe that this is a necessary component of any account of interests.

Do young children have a teleological conception of the essence of natural kinds? We tested this by examining how the preservation or alteration of an animal’s purpose affected children’s persistence judgments (N = 40, ages 4 - 12, Mean Age = 7.04, 61% female). We found that even when surface-level features of an animal (e.g., a bee) were preserved, if the entity’s purpose changed (e.g., the bee now spins webs), children were more likely to categorize the entity as a member (...) of a different natural kind (e.g., a spider) and these effects were similar in magnitude to altering the surface-features of a natural kind. Our results suggest that we might view teleological properties as partially constitutive of the essence of natural kinds. (shrink)

Thinking in terms of purposes is inevitable in daily life. We make to-do lists and we go to the store “in order to” stock up on necessities. We enroll in education and training courses, buy or rent property, and commit to a romantic partner. Our religions, albeit controversially, identify “ultimate purposes.” Purpose thinking seems deeply engrained in our cognition. Even so, purpose thinking has never sat easily with post-Cartesian modern science. When the world is modeled as a structure of efficient (...) causes, then the apparent existence of final causes becomes an explanandum. (shrink)

Neo‐Aristotelian ethical naturalism purports to show that moral evaluation of human action and character is an evaluation of natural goodness—a kind of evaluation that applies to living things in virtue of their nature and based on their form of life. The standard neo‐Aristotelian view defines natural goodness by way of generic statements describing the natural history, or the ‘characteristic’ life, of a species. In this paper, I argue that this conception of natural goodness commits the neo‐Aristotelian view to a problematic (...) anti‐individualism that results in the wrong assessment of individuals with uniquely adaptive adjustments. I then offer an alternative account of natural goodness that avoids this problem. Instead of relying on generic statements about a species, my account defines natural goodness based on counterfactual conditionals describing the modal properties of a single individual. I argue that this modal‐explanatory account gives a conception of natural goodness that is more intuitively plausible and better suited to capture the diversity and plasticity distinctive of life.

Accounting for qualia in the natural world is a difficult business, and it is worth understanding why. A close examination of several theories of mind—Behaviorism, Identity Theory, Functionalism, and Integrated Information Theory—will be discussed, revealing shortcomings for these theories in explaining the contents of conscious experience: qualia. It will be argued that in order to overcome the main difficulty of these theories the senses should be interpreted as physical detectors. A new theory, Grounded Functionalism, will be proposed, which retains multiple (...) realizability while allowing for a scientifically based approach toward accounting for qualia in the natural world.

The first hint of how to begin our inquiry is given in the second aphorism of Vedanta-sutra. Janmadasya yatah. Janma means birth, and asya refers to all that has been created from Brahman or the original source - which is spirit. Brahman means Spirit or God. It is not a matter of merely knowing what is immediately present before us. We want to know where it all comes from. This is actually very practical if we want to properly understand anything. (...) For example, let us say an aboriginal villager enters a city for the first time in his life and sees numerous skyscraper buildings. He may think these buildings to be natural features of the environment, just like the caves in his mountain village. Thus, in order to properly understand what a building is, not only its present appearance but how it got there, or where it came from is necessary. Only then can one say that he has properly understood what a building is. Likewise, scientists are not merely interested in observing the world, they want to understand what is beyond its immediate appearance, and comprehend what principle constituents it comes from - what has made or caused it to be what we observe. This is what we mean by scientific understanding. (shrink)

There is a nested hierarchy of wholes that characterizes reality, and especially life. The most fundamental principle is that Reality in the Vedantic/Bhagavat conception is based on Personality, as mentioned in the very first aphorism of the Bhagavat Purana, “janmady asya yatho nvayat itaratas charteshu abhijnah svarat.” Here and in many other scriptures the foundation or origin of everything is centered upon the abhijna or cognizant (conscious) primordial Personality of Godhead. Modern science in the West has become centered on matter (...) as the foundation of everything, and this is called materialism. But matter is impersonal. The question is: how can a person come from what is impersonal? We consider such an approach to be backward. Person cannot come from an impersonal material substratum. It is very difficult to conceive how a rock can give rise to a concept of rock. But it is quite natural to understand that a rock exists as a concept for a conscious person. So too can the concept of objectivity, concreteness and perception arise from a personal substratum, and historically, this has been demonstrated by the detailed philosophical study of these ideas by numerous philosophers.

The neo-Darwinian theory of genetic random mutation and Natural Selection, does nothing to explain speciation. Thus, what has been called "natural selection" has come under much scrutiny and critique in recent times. The problem is that natural selection requires the existence of a stable array of species from which selection can be made. So natural selection does not perform the speciation, only the selection after speciation has occurred. The activity of creating new species must therefore lie in the random mutations (...) of the genome. But this raises the problem that such mutations are generally always fatal to the organism, plus a whole host of other problems that modern advances in molecular biology have revealed about the detailed mechanisms occurring in DNA replication processes, including such things as intrinsic error correcting mechanisms during DNA transcription. Thus a theory of how species arise (speciation) does not currently exist in biology. The Vedantic/Bhagavat paradigm rejects the objectivist theory of evolution as not only wrong but an impediment to the actual scientific comprehension of Nature. The Vedantic conception of Life is a fully differentiated/determinate one that displays its variety in and as an dynamic organic whole. The crucial element of interdependence that is missing in modern theories of insular organism life is fully embraced in what we may call the Post-Darwinian, post-reductionist, post-modern conception of Life the Vedantic/Bhagavat conception offers.

The Western world has led the development of material science for over 200 years. But they have reached an impasse in confronting the problem of consciousness. Scientific knowledge requires a scientist, but regarding knowledge concerning the scientist, they must remain silent. India has always emphasized knowledge of the conscious self or atma. Vedanta-sutra begins with the aphorism “athatho brahma jijnasa” – now, therefore, inquire about brahma (pure consciousness). Even in the West, the Greek philosopher Socrates stated, “Above all else know (...) the self.” But since the time of Newton, the objective world became the focus of science to the exclusion of the conscious observer or scientist.

Modern science generally assumes that the same laws of logic apply to mechanical, chemical and biological entities alike because they are all ultimately material objects. This may seem to be so obvious that there would be no need to validate it -- experimentally or logically. In this article we would like to critically examine this assumption and show that from an experiential/observational level, as well as from a rational/logical level, it is not valid. This becomes apparent, for instance, when we (...) consider the simple observation in which we distinguish animate from inanimate objects: those objects that seem to spontaneously move themselves and those that move only when impelled by some applied force outside or beyond the object. This distinction may be valid at the macroscopic level more than at the level of theoretical atomic particles. Thus the detailed nature of spontaneous movement must also be understood. (shrink)

According to the current scientific paradigm, what we call ‘life’, ‘mind’, and ‘consciousness’ are considered epiphenomenal occurrences, or emergent properties or functions of matter and energy. Science does not associate these with an inherent and distinct existence beyond a materialistic/energetic conception. ‘Life’ is a word pointing at cellular and multicellular processes forming organisms capable of specific functions and skills. ‘Mind’ is a cognitive ability emerging from a matrix of complex interactions of neuronal processes, while ‘consciousness’ is an even more elusive (...) concept, deemed a subjective epiphenomenon of brain activity. Historically, however, this has not always been the case, even in the scientific and academic context. Several prominent figures took vitalism seriously, while some schools of Western philosophical idealism and Eastern traditions promoted conceptions in which reality is reducible to mind or consciousness rather than matter. We will argue that current biological sciences did not falsify these alternative paradigms and that some forms of vitalism could be linked to some forms of idealism if we posit life and cognition as two distinct aspects of consciousness preeminent over matter. However, we will not argue in favor of vitalistic and idealistic conceptions. Rather, contrary to a physicalist doctrine, these were and remain coherent worldviews and cannot be ruled out by modern science. (shrink)

At the beginning of the twentieth century, the French philosopher of science Edmond Goblot wrote three prescient papers on function and teleology. He advanced the remarkable thesis that functions are, as a matter of conceptual analysis, selected effects. He also argued that “selection” must be understood broadly to include both evolutionary natural selection and intelligent design. Here, I do three things. First, I give an overview of Goblot’s thought. Second, I identify his core thesis about function. Third, I argue that, (...) despite its ingenuity, Goblot’s expansive construal of function cannot be right. Still, Goblot deserves long-overdue credit for his work. (shrink)

The selected effects or ‘etiological’ theory of Proper function is a naturalistic and realist account of biological teleology. It is used to analyse normativity in philosophy of language, philosophy of mind, philosophy of medicine and elsewhere. The theory has been developed with a simple and intuitive view of natural selection. Traits are selected because of their positive effects on the fitness of the organisms that have them. These ‘selected effects’ are the Proper functions of the traits. Proponents argue that this (...) analysis of biological teleology has the unique advantage that the selected effect function of a trait is also a causal explanation of the trait: the trait exists because it performs this function. We show, however, that selected effect functions as currently defined explain the existence of traits only under highly restrictive assumptions about evolutionary dynamics. In many common scenarios in which traits evolve by natural selection, selected effect functions do not explain those traits. This is because definitions of selected effect function extract from any evolutionary scenario only the information that would be explanatorily relevant in the simple evolutionary scenario implicit in those definitions. When applied to more complex scenarios selected effect functions omit the key information that is explanatorily relevant in those scenarios. The assumptions required for selected effect functions to be explanatory are particularly unlikely to hold in the domain that its proponents care most about - the evolution of representation. A more adequate selected effects theory of Proper functions may be possible, but will require much greater attention to the structure of actual evolutionary explanations. (shrink)

The extensive philosophical discussions and analyses in recent decades of function-talk in biology have done much to clarify what biologists mean when they ascribe functions to traits, but the basic metaphysical question—is there genuine teleology and design in the natural world, or only the appearance of this?—has persisted, as recent work both defending, and attacking, teleology from a Darwinian perspective, attest. I argue that in the context of standard contemporary evolutionary theory, this is for the most part a verbal, rather (...) than a substantive dispute: the disputants are talking past one another. To justify this claim I develop a general framework within which reductionist views, such as the standard ‘etiological’ account of biofunctions, occupy an intermediate position between what I call full-blooded realism and full-blooded anti-realism, and suggest that whether such views count as ‘realist’ views has no objective, theory-neutral answer.

This paper explores the significance of intelligent social behavior among non-human animals for philosophical theories of communication. Using the alarm call system of vervet monkeys as a case study, I argue that interpersonal communication (or what I call “minded communication”) can and does take place in the absence of the production and recognition of communicative intentions. More generally, I argue that evolutionary theory provides good reasons for maintaining that minded communication is both temporally and explanatorily prior to the use of (...) communicative intentions. After developing these negative points about the place of communicative intentions in detail, I provide a novel alternative account according to which minded communication is characterized in terms of patterns of action and response that function to coordinate the representational mental states of agents. I show that an account which centers on patterns of representational coordination of this sort is well suited to capture the theoretical roles associated with minded communication and that it does so in a way that provides a good fit with comparative facts about the presence of minded communication among non-human animals.

Robert Adams defends a platonic account of goodness, understood as excellence, claiming that there exists a platonic good that all other good things must resemble, identifying the Good with God. Mark Murphy agrees, but argues that this platonic account is in need of Aristotelian supplementation, as resemblance must take into account a thing’s kind-membership. While this article will accept something like Murphy’s account of goodness, it will further develop its details and support. Without relying on theistic premises, I show that (...) the metaphysical status of an individual’s goodness consists in resemblance with the platonic good. As for the distinct question of what that goodness holds in virtue of, I conclude it holds in virtue of exactly: the thing’s own properties, those properties being such as to satisfy its kind-based standards, and those K-standards resembling the platonic good. I then develop an account of how K-standards resemble the platonic good: The K-standards resemble it firstly with respect to requiring activities, as the platonic good will be posited to be active, and must resemble it secondly also at the level of what teleology those activities are directed towards. I also motivate the need for a third respect of resemblance, to be developed in future work. The article ends with a discussion of the nature of the platonic good. (shrink)

It should now be recognized that codes are central to life and to understanding its more complex forms, including human culture. Recognizing the ‘conventional’ nature of codes provides solid grounds for rejecting efforts to reduce life to biochemistry and justifies according a place to semantics in life. The question I want to consider is whether this is enough. Focussing on Eigen’s paradox of how a complex code could originate, I will argue that along with Barbieri’s efforts to account for the (...) origins of life based on the ribosome and then to account for the refined codes through a process of ambiguity reduction, something more is required. Barbieri has not provided an adequate account of emergence, or the basis for providing such an account. I will argue that Stanley Salthe has clarified to some extent the nature of emergence by conceptualizing it as the interpolation of new enabling constraints. Clearly, codes can be seen as enabling constraints. How this actually happens, though, is still not explained. Stuart Kauffman has grappled with this issue and shown that it radically challenges the assumptions of mainstream science going back to Newton. He has attempted to reintroduce real possibilities or potentialities into his ontology, and argued that radically new developments in nature are associated with realizing adjacent possibles. This is still not adequate. What is also involved, I will suggest, utilizing concepts developed by the French natural philosopher Gilbert Simondon, is ‘transduction’ as part of ‘ontogenesis’ of individuals in a process of ‘individuation’, that is, the emergence of ‘individuals’ from preindividual fields or milieux.

Aristotelian theory, as found in Michael Thompson and Philippa Foot, claims that to be good is to be good as a member of that kind. Moreover, Foot argues in effect that goodness admits of only the kind-based sort, obtaining solely in virtue of something’s satisfying kind-based standards. However, I contend that something can satisfy kind-relative standards but nonetheless be bad—I propose a hypothetical Ebola-like microbe that meets its kind-standards of being destructive for its own sake, but it would plausibly be (...) bad for doing so. In defending my counterexample, I respond to the Aristotelian contention that evaluations should only be made from “within” the standpoint of a particular lifeform conception, rather than an “external” one from which that kind itself can be judged to be bad.

Jonathan Y. Tsou examines and defends positions on central issues in philosophy of psychiatry. The positions defended assume a naturalistic and realist perspective and are framed against skeptical perspectives on biological psychiatry. Issues addressed include the reality of mental disorders; mechanistic and disease explanations of abnormal behavior; definitions of mental disorder; natural and artificial kinds in psychiatry; biological essentialism and the projectability of psychiatric categories; looping effects and the stability of mental disorders; psychiatric classification; and the validity of the DSM's (...) diagnostic categories. The main argument defended by Tsou is that genuine mental disorders are biological kinds with harmful effects. This argument opposes the dogma that mental disorders are necessarily diseases that result from biological dysfunction. Tsou contends that the broader ideal of biological kinds offers a more promising and empirically ascertainable naturalistic standard for assessing the reality of mental disorders and the validity of psychiatric categories.

There is a certain metaphor that has enjoyed tremendous longevity in the evolution of ageing literature. According to this metaphor, nature has a certain goal or purpose, the perpetuation of the species, or, alternatively, the reproductive success of the individual. In relation to this goal, the individual organism has a function, job, or task, namely, to breed and, in some species, to raise its brood to maturity. On this picture, those who cannot, or can no longer, reproduce are somehow invisible (...) to, or even dispensable to, the evolutionary process. Here, I argue that the metaphor should be discarded, not on the grounds that it is a metaphor, but on the grounds that this particular metaphor distorts our understanding of the evolution of ageing. One reason the metaphor is problematic is that it frames senescence and death as nature’s verdict on the value of older individuals. Instead, we should explore a different metaphor: the lengthy post-reproductive period in humans and some other animals is not an accident of culture, but designed by nature for the purpose of supporting and guiding younger generations. On this alternate picture, different stages of life have their own evolutionary rationales, their distinctive design features, their special mandates. (shrink)

Mechanisms, in the prominent biological sense of the term, are historical entities. That is, whether or not something is a mechanism for something depends on its history. Put differently, while your spontaneously-generated molecule-for-molecule double has a heart, and its heart pumps blood around its body, its heart does not have a mechanism for pumping, since it does not have the right history. My argument for this claim is that mechanisms have proper functions; proper functions are historical entities; so, mechanisms are (...) historical entities, too. This thesis runs against the mainstream new mechanist way of thinking about mechanisms, where mechanisms are generally thought of in an ahistorical way. After arguing for this thesis, I draw out some consequences for philosophy of science and metaphysics. (shrink)

Kinds that share historical properties are dubbed “historical kinds” or “etiological kinds,” and they have some distinctive features. I will try to characterize etiological kinds in general terms and briefly survey some previous philosophical discussions of these kinds. Then I will take a closer look at a few case studies involving different types of etiological kinds. Finally, I will try to understand the rationale for classifying on the basis of etiology, putting forward reasons for classifying phenomena on the basis of (...) diachronic features, thereby making a provisional case for considering at least some etiological kinds to be natural kinds.

An affective approach to culture and cognition may hold the key to uniting findings across experimental psychology and, eventually, the human sciences. Many accounts of the human mind concentrate on the brain’s computational power, yet for nearly 200 million years before humans developed a capacity to reason the emotional centers of the brain were running the show. To attain a clearer picture of the evolution of mind, we challenge the cognitivist and behaviorist paradigms in psychology by exploring how the emotional (...) capacities that we share with other animals saturate every thought and perception. Many of the distinctive social and cultural behaviors of our species, including, bonding, social learning, hierarchy, decision-making, self-identity, can be integrated if we use an affective approach.

It was commonly accepted in Goethe’s time that plants were equipped both to propagate themselves and to play a certain role in the natural economy as a result of God’s beneficent and providential design. Goethe’s identification of sexual propagation as the “summit of nature” in The Metamorphosis of Plants (1790) might suggest that he, too, drew strongly from this theological-metaphysical tradition that had given rise to Christian Wolff’s science of teleology. Goethe, however, portrayed nature as inherently active and propagative, itself (...) improvising into the future by multiple means, with no extrinsically pre-ordained goal or fixed end-point. Rooted in the nature philosophy of his friend and mentor Herder, Goethe’s plants exhibit their own historically and environmentally conditioned drives and directionality in The Metamorphosis of Plants. In this paper I argue that conceiving of nature as active productivity—not merely a passive product—freed Goethe of the need to tie plants’ forms and functions to a divine system of ends, and allowed him to consider possibilities for plants, and for nature, beyond the walls of teleology.

In a series of papers, Papineau argues that the Swampman scenario is not even the start of an objection to teleosemantics as a scientific reduction of belief. It is against this claim that I want to argue here. I shall argue that our intuition about the scenario questions the adequacy of the conceptual foundations of teleosemantics, namely, success semantics and the etiological conception of biological function, on which the explanatory power of the theory rests. In the course of argument, some (...) general connections between explanation and modality will be developed that shed a new light on Kripke’s analysis of necessary a posteriori propositions. The upshot will be that teleosemanticists should tackle the Swampman objection head-on. (shrink)

In De usu partium, Galen argues that the parts of the human body are designed to fulfill functions that contribute to the continued existence and well-being of the organism as a whole. Synthesizing Plato’s and Aristotle’s views on teleology, Galen highlights the importance of a functional framework for anatomical research. For Galen, teleology is as much a method for anatomical inquiry as it is a metaphysical commitment. In particular, teleology guides the main tool of anatomical investigation: dissection. According to Galen, (...) the success of medical research and practice requires classifying, individuating, and explaining anatomical parts in light of their functional contributions. (shrink)

Eshel Ben-Jacob’s manuscript entitled ‘Bacterial wisdom, Gödel’s theorem and creative genomic webs’ summarizes decades of work demonstrating adaptive mutagenesis in bacterial genomes. Bacterial genomes, each an essential part of a Kantian whole that is a single bacterium, are thus not independent of the environment as sensed; and a single bacterium is therefore a semiotic entity. Ben-Jacob suggests this but errs in 1) assigning autonomy to the genome, and 2) analogizing through computation without making clear whether he is doing so for (...) illustrative purposes or making committed ontological propositions. We reinterpret adaptive mutagenesis and related phenomena in ways both metaphysically rigorous and revealing. We conclude that bacteria are much farther removed from the ‘self-organizing’ world of inanimate process than from the Peircian world of signs; and a critical reappraisal of existing knowledge can enhance our understanding of selfhood, semiosis, and the roots of subjective experience.
