Teleology and Function, Misc

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)

Nietzsche’s injunction to examine “the value of values” can be heard in a pragmatic key, as inviting us to consider not whether certain values are true, but what they do for us. This oddly neglected pragmatic approach to Nietzsche now receives authoritative support from Bernard Reginster’s new book, which offers a compelling and notably cohesive interpretation of Nietzsche’s On the Genealogy of Morality. In this essay, I reconstruct Reginster's account of Nietzsche’s critique of morality as a “self-undermining functionality critique” and (...) raise three problems for it: (i) Is there room within an etiological conception of function for the notion of self-undermining functionality? (ii) If Nietzsche’s critique is internal and based solely on the function it ascribes to morality, where does that critique derive its normative significance from? (iii) Does Reginster’s account not make out ascetic morality to be more universally dysfunctional than it in fact is, given that some priestly types have done remarkably well out of morality?

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.

Millikan’s (1984. Language, Thought, and Other Biological Categories: New Foundations for Realism. MIT Press) selected effects theory of functions states that functions are effects for which the ancestors of a trait were selected for. As the function is an effect a thing’s ancestors produced, only things that are reproductions in some sense can have functions. Against this reproduction requirement, Garson (2019. What Biological Functions Are and Why They Matter. Cambridge University Press) argues that not only processes of differential reproduction but (...) also processes of differential persistence can lead to new functions. Since such “persistence functions” have the same explanatory power as traditional selected effects functions, selected effects theorists should include them in their theory. In this paper, I will defend Millikan’s theory against this argument. I will show that the proponents of the generalized theory have yet to provide a working notion of populations that avoids a liberality problem. Further, I will argue that persistence functions are at best a marginal case of functions due to their restricted explanatory power. (shrink)

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.

Biogenic approaches investigate cognition from the standpoint of evolutionary function, asking what cognition does for a living system and then looking for common principles and exhibitions of cognitive strategies in a vast array of living systems—non-neural to neural. One worry which arises for the biogenic approach is that it is overly permissive in terms of what it construes as cognition. In this paper I critically engage with a recent instance of this way of criticising biogenic approaches in order to clarify (...) their theoretical commitments and prospects. In his critique of the biogenic approach, Fred Adams uses the presence of intentional states with conceptual content as a criterion to demarcate cognition-driven behaviour from mere sensory response. In this paper I agree with Adams that intentionality is the mark of the cognitive, but simultaneously reject his overly restrictive conception of intentionality. I argue that understanding intentionality simpliciter as the mark of the mental is compatible with endorsing the biogenic approach. I argue that because cognitive science is not exclusively interested in behaviour driven by intentional states with the kind of content Adams demands, the biogenic approach’s status as an approach to cognition is not called into question. I then go on to propose a novel view of intentionality whereby it is seen to exist along a continuum which increases in the degree of representational complexity: how far into the future representational content can be directed and drive anticipatory behaviour. Understanding intentionality as existing along a continuum allows biogenic approaches and anthropogenic approaches to investigate the same overarching capacity of cognition as expressed in its different forms positioned along the continuum of intentionality. Even if all organisms engage in some behaviour that is driven by weak intentional dynamics, this does not suggest that every behaviour of all organisms is so driven. As such, the worry that the biogenic approach is overly permissive can be avoided. (shrink)

This Element focuses on three challenges of evolution to religion: teleology, human origins, and the evolution of religion itself. First, religious worldviews tend to presuppose a teleological understanding of the origins of living things, but scientists mostly understand evolution as non-teleological. Second, religious and scientific accounts of human origins do not align in a straightforward sense. Third, evolutionary explanations of religion, including religious beliefs and practices, may cast doubt on their justification. We show how these tensions arise and offer potential (...) responses for religion. Individual religions can meet these challenges, if some of their metaphysical assumptions are adapted or abandoned.

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)

Chance and necessity are mainstays of explanation in current biology, dominated by the neo-Darwinian outlook, a blend of the theory of evolution by natural selection with the basic tenets of population genetics. In such a framework the form of living organisms is somehow a side effect of highly contingent, historical accidents. Thus, at a difference of other sciences, biology apparently lacks theoretical principles that in a law-like fashion may explain the emergence and persistence of the characteristic forms of living organisms (...) that paradoxically, given the current importance attributed to chance, can be grouped into organized structural typologies. Nevertheless, the present essay shows that since its origins in Aristotelian natural history, biology aimed at achieving rational, non-accidental, explanations for the wide variety of living forms endowed with characteristic behaviors that constitute the landscape of biological species.

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.

A new theory that naturalizes biological function is explained and compared with earlier etiological and causal role theories. Etiological theories explain functions from how they are caused over their evolutionary history. Causal role theories analyze how functional mechanisms serve the current capacities of their containing system. The new proposal unifies the key notions of both kinds of theories, but goes beyond them by explaining how functions in an organism can exist as factors with autonomous causal efficacy. The goal-directedness and normativity (...) of functions exist in this strict sense as well. The theory depends on an internal physiological or neural process that mimics an organism’s fitness, and modulates the organism’s variability accordingly. The structure of the internal process can be subdivided into subprocesses that monitor specific functions in an organism. The theory matches well with each intuition on a previously published list of intuited ideas about biological functions, including intuitions that have posed difficulties for other theories.

In this paper I defend a pluralistic approach in understanding function, both in biological and other contexts. Talks about function are ubiquitous and crucial in biology, and it might be the key to bridge the “manifest image” and the “scientific image” identified by Sellars (1962). However, analysis of function has proven to be extremely difficult. The major puzzle is to make sense of “time-reversed causality”: how can property P be the cause of its realizer R? For example, “pumping blood” is (...) a property of hearts, but a property of hearts cannot be the cause of the presence of hearts, since properties cannot predate their realizers and be causes of them. In section 2 I discuss Wright’s etiological analysis, Cummins’ causal-role analysis, and their critics. In section 3 I defend a version of the “consensus without unity” strategy proposed by Godfrey-Smith from Christopher Boorse’s recent critique (2002). In Section 4 I conclude by reflecting on the relation between functional discourses and physicalism. (shrink)

This book chapter is a short response to a paper by the psychiatrist Nicholas Kontos, on the phenomenon of psychological symptom amplification (PSA). PSA takes place when patients present symptoms to clinicians that they do not actually have, or, perhaps more commonly, they exaggerate symptoms they do have. Kontos argues that, because of modern medical training, it is very difficult for clinicians to recognize that the patient's presented symptoms are exaggerated or nonexistent. I argue that the hiddenness of PSA is (...) a result of far-reaching instutitional changes that took place in American psychiatry in the 1970s. In short, many psychiatrists went from seeing mental disorders as (unconscious) strategies to seeing them as dysfunctions, nothing more. Recognizing PSA involves adopting a perspective that has been effectively abolished in contemporary American psychiatry. (shrink)

Starting with Aristotle and moving on to Darwin, Marco Solinas outlines the basic steps from the birth, establishment and later rebirth of the traditional view of living beings, and its overturning by evolutionary revolution. The classic framework devised by Aristotle was still dominant in the 17th Century world of Galileo, Harvey and Ray, and remained hegemonic until the time of Lamarck and Cuvier in the 19th Century. Darwin's breakthrough thus takes on the dimensions of an abandonment of the traditional finalistic (...) theory. It was a transition exemplified in the morphological analysis of useless parts, such as the sightless eyes of moles, already discussed by Aristotle, which Darwin used as a crowbar to unhinge the systematic recourse to final causes. With many excerpts, a chronological sequence and an analytical approach, this book follows the course of the two conceptions that have shaped the destiny of life sciences in western culture.

Epistemic warrant consists in the normal functioning of the belief-forming process when the process has forming true beliefs reliably as an etiological function. Evolution by natural selection is the most familiar source of etiological functions. . What then of learning? What then of Swampman? Though functions require history, natural selection is not the only source. Self-repair and trial-and-error learning are both sources. Warrant requires history, but not necessarily that much.

To understand Darwin’s concept of natural selection, we have to contrast it with his characterization of artificial selection, and then ask: what is natural in natural selection? While we do this, we develop two distinctions: one between ‘change by transformative action’ and ‘change by selection’, and another between ‘artificial selection’ and ‘natural selection’. The first distinction helps us understand evolution by selection and the second natural selection.

The scientific study of living organisms is permeated by machine and design metaphors. Genes are thought of as the ‘‘blueprint’’ of an organism, organisms are ‘‘reverse engineered’’ to discover their functionality, and living cells are compared to biochemical factories, complete with assembly lines, transport systems, messenger circuits, etc. Although the notion of design is indispensable to think about adaptations, and engineering analogies have considerable heuristic value (e.g., optimality assumptions), we argue they are limited in several important respects. In particular, the (...) analogy with human-made machines falters when we move down to the level of molecular biology and genetics. Living organisms are far more messy and less transparent than human-made machines. Notoriously, evolution is an opportunistic tinkerer, blindly stumbling on ‘‘designs’’ that no sensible engineer would come up with. Despite impressive technological innovation, the prospect of artificially designing new life forms from scratch has proven more difficult than the superficial analogy with ‘‘programming’’ the right ‘‘software’’ would suggest. The idea of applying straightforward engineering approaches to living systems and their genomes— isolating functional components, designing new parts from scratch, recombining and assembling them into novel life forms—pushes the analogy with human artifacts beyond its limits. In the absence of a one-to-one correspondence between genotype and phenotype, there is no straightforward way to implement novel biological functions and design new life forms. Both the developmental complexity of gene expression and the multifarious interactions of genes and environments are serious obstacles for ‘‘engineering’’ a particular phenotype. The problem of reverse-engineering a desired phenotype to its genetic ‘‘instructions’’ is probably intractable for any but the most simple phenotypes. Recent developments in the field of bio-engineering and synthetic biology reflect these limitations. Instead of genetically engineering a desired trait from scratch, as the machine/engineering metaphor promises, researchers are making greater strides by co-opting natural selection to ‘‘search’’ for a suitable genotype, or by borrowing and recombining genetic material from extant life forms.

Origin of life studies have presented one of the most serious challenges to the mechanistic conception that life can be explained scientifically as a mere product of chemistry and physics. Hypotheses about the origin of life can be divided into two categories: (1) biogenesis – life comes from life, and (2) abiogenesis – life comes from non-living matter. The theory of the spontaneous generation of life from inanimate matter had been held even by the ancient Greeks and by numerous scientists (...) well into the 19th century. The theory of abiogenesis poses many problems for understanding the origin of life on Earth, and the appearance of life early in Earth’s history. Numerous chemical, mathematical and informational problems arise which make random mechanical processes of cellular formation and function unlikely. Fossil evidence contradicts a gradualist evolutionary mechanism of development of life, especially the well-known Cambrian explosion, in which highly developed metazoan species suddenly appear in the geological column without intermediate predecessors. But the physical conundrums that mechanistic theories of chemistry and physics face are only one side of the problem. Along with a rising chorus of philosophers, Thomas Nagel, an atheist philosopher, has protested that essential questions about the origin of life, and features such as mind, intelligence and morality are completely left unexplained by mechanistic evolutionary theories. In Mind and Cosmos: Why the Materialist Neo-Darwinian Conception of Nature Is Almost Certainly False, Nagel plainly lays out his argument that the modern materialist approach to life has conspicuously failed to explain something so integral to nature as mind or consciousness, thereby threatening to unravel the entire naturalistic world picture of biology, evolutionary theory and cosmology. [13] As an alternative he argues that at least natural teleological principles must be admitted to play a role in our view of science. He writes: “Each of our lives is a part of the lengthy process of the universe gradually waking up and becoming aware of itself.” The Vedantic view of the Absolute as sentient conceives of Bhagavan as the conscious and consequently personal source of the universe. This view holds that life is fundamental, and not merely coextensive with matter. It is thus consistent with the law of biogenesis which is scientifically established in agreement with empirical evidence. Life is the basis of Nature, not matter, and Nature is a system in which the different species are nodes or niches, each possessed of variety and adaptability. Evolution is of consciousness, not of the bodies of organisms. The sedimentary fossils are the result of catastrophic deposits, and are thus not indicative of gradual evolution which is concluded only on the questionable assumption of uniformitarianism.

Are physics and chemistry sufficient to provide a basis for a theory of everything? The worldview of materialist naturalism that forms the foundation of NeoDarwinian evolution, Big Bang cosmogony, and molecular biology in general has been subjected to challenge for its monumental failure to explain life, consciousness and other mind-related aspects of reality. Two recent books, Why Evolution is True by Jerry Coyne [1], and Thomas Nagel’s Mind and Cosmos: Why the Materialist NeoDarwinian Conception of Nature Is Almost Certainly False (...) [2], both authors being atheists, reflect the deep rift we find, not only in the religious conflict between creation and evolution, but in the fundamental awareness we all have that we are more than just molecular matter. This common sense understanding can only escape the notice of a particularly shallow ideological dogmatism that insists it has all the answers based solely on its unprecedented technological success. Science has come to represent two different things: (a) a body of knowledge, and (b) a method for acquiring knowledge. The problem arises when it is forgotten that there is no independent body of knowledge for science apart from its method – it keeps changing according to the results of the latest findings of the scientific method. The method is not to be abandoned because of those who would like to replace it with a fixed body of knowledge, which then becomes ideology. If biogenesis is hypothesized as the law of Nature, and we observe that life comes from pre-existing life in all our experience, while the hypothesis of abiogenesis, that life comes from matter, is never backed by any observation, then according to the scientific method—which one is to be accepted as true scientific knowledge? Obviously, the one backed by empirical observation. It is necessary to get free of ideological “knowledge,” and return to science as a method for gathering evidence that may lead to conclusions beyond the material naturalist view of Nature, and conforms to what we experience and rationally understand about the world in which we live.

The study of organisms within the range of their existence from fertilization to birth is referred to as embryology. The process of progressive change during that period is called development. That development does not stop at birth but continues on throughout the entire life-span of the organism as the process of growth and decay — catabolism, anabolism, and metabolism. The study of this entire range of life has recently become known as developmental biology. The belief that the development from an (...) initial stage of a fertilized egg or zygote to a fully formed adult represents, in compressed time, the whole process of evolution that occurred over millions of years, has recently been named evo-devo, or evolutionary development. The more science advances, the more it studies Nature in its intimate details, the more it comes to realize the existence of a pervasive reason, an inherent natural intelligence that is working in even the most insignificant portions of the universe. Francis Bacon (1561–1626) said, “A little philosophy (science) inclineth man's mind to atheism, but depth in philosophy (science) bringeth men's minds about to religion.” This point is especially true today. It is not from ignorance that men come to have faith in God, but from a maturity of reason and experience. Vedanta philosophy teaches that there is a conscious intelligence that underlies all experienced existence. Being self-evident, this should hardly have to be argued. Yet modern science has failed to integrate this truth into its materialist/naturalistic paradigm. Correcting this deficiency will be the challenge of 21st century science, and the highest reward for humanity. (shrink)

We received several critical comments regarding the "The Science of Spiritual Biology." We reply to those criticisms in order to further clarify some of the important points that were made.

This chapter deals with the way our psychology and actions a scaffolded by their environment but also the tensions that can appear between individual and environment, both at the level of biology and culture. The chapter is grounded in an analysis of the early 20th century theoretical biologist Jacob von Uexkull and his notion of "Umwelt" or "surround world". But also raises the question of whether organisms fit their environment as neatly as Uexkull and many later thinkers have proposed or (...) assumed. (shrink)

"Living systems are cognitive systems, and living as a process is a process of cognition." -H.R. Maturana, The Biology of Cognition (1970/1980) Just as the cell has gradually come to be understood as a highly regulated and unctionally integrated whole, so too is the biosphere now recognized as a finely balanced ecological whole in which local disturbances can create world-wide climatic catastrophe. The oversimplified ideas of biology that characterized the field in its immature beginning led to the theories of a (...) progressive cumulative development or evolution to explain the present state of Nature. However, today, a more mature understanding of biology has brought with it the realization that Nature can not be the product of a gradual development, based only on the reductionist principles of chemistry and physics. In an ideal situation, where there are no strong interactions with the environment, isolated and purified chemicals may react in a mechanically simple manner, but in a living organism there are no isolated molecules. Everything within the cell interacts with everything else. The constituents of a cell are produced by the cell as much as they produce the cell itself. As the German philosopher Immanuel Kant understood, the unique judgment that allows us to identify a living organism as distinct from non-living matter, is that a living organism is both the cause and effect of itself. Thus, the life of a cell, as much as the life of the biosphere, can only be properly understood as an integrated organic whole. (shrink)

This is a short overview of the biological functions debate in philosophy. While it was fairly comprehensive when it was written, my short book ​A Critical Overview of Biological Functions has largely supplanted it as a definitive and up-to-date overview of the debate, both because the book takes into account new developments since then, and because the length of the book allowed me to go into substantially more detail about existing views.

n this article the author develops a critique of reductionism in biological sciences from three different points of view. The first is related to the problem of reduction in the context of scientific theories. More specifically, reduction deals with a special form of intertheoretic relationship between molecular biology and the rest of biology. The second meaning of reductionism has to do with the significance of its genetic outfit for the ontogeny of an organism, i.e. its development from zygote to its (...) final or adult structure and function. Third, closely related to this more biological topic are questions about the anthropological consequences of the application of reductionistic methodologies for the explanation and evaluation of human behaviour.

This paper explores the critical conditions of such semiotic realism that is commonly presumed in the so-called Copenhagen interpretation of biosemiotics. The central task is to make basic biosemiotic concepts as clear as possible by applying C.S. Peirce’s pragmaticist methodology to his own concepts, especially to those that have had a strong influence on the Copenhagian biosemiotics. It appears essential to study what kinds of observation the basic semiotic concepts are derived from. Peirce had two different derivations to the concept (...) of sign, both having a strong logical character. Therefore, it is discussed at length what Peirce’s conception of logic consists of and how logical concepts relate to the concepts of other sciences. It is shown that Peirce had two different perspectives toward sign, the ‘transcendental’ one and the objective one, and only the latter one is executable in biosemiotic applications. Although Peirce’ theory of signs seems to appear as twofold (if not even manifold), it is concluded that the ore conception has been stable. The apparent differences are presumably due to the different perspectives of consideration. Severe limitations for the application of Peirce’s semiotic concepts follow from this analysis that should be taken into account in biosemiotics relying on its Copenhagen interpretation. The first one concerns the ‘interpreter’ of a suggested biosemiotic sign — whether it is ‘we’ (as a ‘meta-agent’) or some genuine biosemiotic ‘object-agent’. Only if the latter one is determinable, some real biosemiotic sign-action may occur. The second one concerns the application of the concept of the object of sign — its use is limited so that a sign has an object if and only if it seeks a true conception about it. This conclusion has drastic further consequences. Most of the genuinely biosemiotic sign-processes do not tend toward truth about anything but toward various practical ends. Therefore, the logical concept of sign, e.g. the one of Peirce’s semeiotic, is an insufficient concept for biosemiotics. In order to establish a sufficient one, Peircean theoretical ethics and esthetics are introduced. It is concluded that they involve simpler and more general but still normative concept of sign — the concept of anticipative or constructive representation that does not represent any object at all. Instead, it is a completely future-oriented representation that guides action. Objective ethics provides the suitable concept of representation, but it appeals to objective esthetics that provides a theory of (local) natural self-normativity. The concepts of objective logic form the special species of objective ethics. The conclusion is that biosemiotics should be based on applied objective ethics and esthetics rather than on (Peircean semeiotic) logic and its metaphysical application. Finally, the physiosemiotic over-generalization of the concept of sign is shortly discussed. It is suggested that it would be more appropriate to rename such controversial generalizations than to adhere to semiotic terminology. Here, again, Peirce appears as a healthy role model with his ‘ethics of terminology’. (shrink)

Any attempt to develop biosemiotics either towards a new biological ground theory or towards a metaphysics of living nature necessitates some kind of naturalization of its semiotic concepts. Instead of standard physicalistic naturalism, a certain kind of semiotic naturalism is pursued here. The naturalized concepts are defined as referring only to the objects of our external experience. When the semiotic concepts are applied to natural phenomena in biosemiotics, there is a risk of falling into anthropomorphic errors if the semiotic concepts (...) remain mentalistic. It is suggested that there really is an anthropomorphic error or “hidden prototype fallacy” arising from Peirce’s prototype for semiosis: the research process of an experimental scientist. The fallacy lies in the concept of the object of representation — it is questionable whether there are any objects of representation for bacteria and whether the DNA-signs have any objects. The conclusion is that Peircean semiotic concepts are naturalizable but only if they are based on some more primitive concept of representation. The causal origins of representations are not relevant, only their anticipative consequences (i.e. meaning). (shrink)
