It is sometimes argued that autonomous decision-making requires that the decision-maker’s desires are authentic, i.e., “genuine,” “truly her own,” “not out of character,” or similar. In this article, it is argued that a method to reliably determine the authenticity (or inauthenticity) of a desire cannot be developed. A taxonomy of characteristics displayed by different theories of authenticity is introduced and applied to evaluate such theories categorically, in contrast to the prior approach of treating them individually. The conclusion is drawn that, (...) in practice, the authenticity of desires cannot be reliably determined. It is suggested that authenticity should therefore not be employed in informed consent practices in healthcare. (shrink)

Traditional neo-Aristotelian accounts hold that temperance and continence are distinct character traits that are distinguished by the extent to which their bearers experience motivational conflict. In this paper, I formulate two pairs of necessary conditions—which, collectively, I call the conformity thesis—that articulate this distinction. Then, drawing on work in contemporary social and personality psychology, I argue that the conformity thesis is false. Being highly self-controlled is the best, psychologically realistic candidate for continence. However, our best evidence suggests that highly self-controlled/continent (...) people do not experience more or stronger desires that conflict with their evaluative judgments than others, and they are not particularly good at directly resisting these desires. In this way, actual continent people exhibit motivational harmony that is more similar to the traditional picture of temperance. On the other hand, they achieve this harmony because they are able to effectively employ indirect strategies for handling motivational conflict. These strategies are correctly associated with continence. Recognizing that temperance and continence are overlapping character traits puts us in a better position to understand, and design interventions to improve, the neuropsychological capacities that enable humans to intelligently manage their desires.

Respect for autonomy is a central moral principle in bioethics. It is sometimes argued that authenticity, i.e., being “real,” “genuine,” “true to oneself,” or similar, is crucial to a person’s autonomy. Patients sometimes make what appears to be inauthentic decisions, such as when anorexia nervosa patients refuse treatment to avoid gaining weight, despite that the risk of harm is very high. If such decisions are inauthentic, and therefore non-autonomous, it may be the case they should be overridden for paternalist reasons. (...) However, it is not clear what justifies the judgment that someone or something is inauthentic. This article discusses one recent theory of what justifies judgments of inauthenticity. It is argued that the theory is seriously limited, as it only provides guidance in three out of nine identified cases. There are at least six authenticity-related problems to be solved, and autonomy theorists thus have reason to engage with the topic of authenticity in practical biomedicine. (shrink)

The notion of authenticity, i.e., being “genuine,” “real,” or “true to oneself,” is sometimes held as critical to a person’s autonomy, so that inauthenticity prevents the person from making autonomous decisions or leading an autonomous life. It has been pointed out that authenticity is difficult to observe in others. Therefore, judgments of inauthenticity have been found inadequate to underpin paternalistic interventions, among other things. This article delineates what justifies judgments of inauthenticity. It is argued that for persons who wish to (...) live according to the prevailing social and moral standards and desires that are seriously undesirable according to those standards, it is justified to judge that a desire is inauthentic to the extent that it is due to causal factors that are alien to the person and to the extent that it deviates from the person’s practical identity. The article contributes to a tradition of thinking about authenticity which is known mainly from Frankfurt and Dworkin, and bridges the gap between theoretical ideals of authenticity and real authenticity-related problems in practical biomedical settings.

Many libertarians assume that there is a close relation between an individual’s self-ownership and her freedom. That relation needs questioning. In this article it is argued that, even in a pre-property state, self-ownership is insufficient to protect freedom. Therefore, libertarians who believe in self-ownership should either offer a defense of freedom that is independent from their defense of self-ownership, make it explicit that they hold freedom as second to self-ownership (and defend that position), or reconsider the moral basis of their (...) political views.

Huw Price has argued that naturalistic philosophy inevitably leads to a deflationary approach to ontological questions. In this paper, I rebut these arguments. A more substantive, less language-focused approach to metaphysics remains open to naturalists. However, rebutting one of Price’s main arguments requires rejecting Quine’s criterion of ontological commitment. So, even though Price’s argument is unsound, it reveals that naturalists cannot rest content with broadly Quinean, “mainstream metaphysics,” which, I suggest, naturalists also have independent reasons to reject.

This paper draws on work in the sciences of the mind to cast doubt on some assumptions that have often been made in the study of self-control. Contra a long, Aristotelian tradition, recent evidence suggests that highly self-controlled individuals do not have a trait very similar to continence: they experience relatively few desires that conflict with their evaluative judgments and are not especially good at directly and effortfully inhibiting such desires. Similarly, several recent studies have failed to support the view (...) that self-control capacities are constituted, at least in part, by excellent inhibitory executive function ability. I propose an alternative “indirect harmony” hypothesis about trait self-control. According to this hypothesis, if there is a character trait of being highly self-controlled, it consists in motivational harmony within the mind that is brought about through the effective use of indirect resistance strategies that prevent occurrent motivational conflict from emerging in the first place. If this hypothesis is correct, high trait self-control in actual humans does not fit neatly into the traditional categories of either continence or temperance. I conclude by drawing out several implications this hypothesis has for future research on trait self-control and its relation to executive functions. (shrink)

Value conflicts between individualism and collectivism are common. In philosophy, such conflicts have been conceptualized as conflicts between individuality and conformity, among other things. This article develops a more detailed conceptual framework by combining philosophical analysis with empirical observations. The focus is on value conflicts pertaining to LGBT (lesbian, gay, bisexual, and transgender) factors in a non-individualist society (Georgia). Conservative or traditional norms sometimes constrain LGBT individuals by influencing them to adapt to social expectations. The phenomenon is intuitively clear and (...) has been reported on in numerous quantitative investigations. A qualitative study has been conducted on how LGBT individuals in Georgia experience the constraining influence of such norms. Deep interviews (n=8) have clarified how, more precisely, the effects of those influences should be conceptualized. The results indicate that important distinctions between different types of influences, as well as different objects of influence, have been overlooked in previous philosophical inquiries about value conflicts in this context. The conceptual framework developed throughout the article should be of use to philosophers and social scientists studying individualism and collectivism, and to policymakers working with LGBT issues.

The aim of this doctoral thesis is to bridge the gap between theoretical ideals of authenticity and practical authenticity-related problems in healthcare. In this context, authenticity means being "genuine," "real," "true to oneself," or similar, and is assumed to be closely connected to the autonomy of persons. The thesis includes an introduction and four articles related to authenticity. The first article collects various theories intended to explain the distinction between authenticity and inauthenticity in a taxonomy that enables oversight and analysis. (...) It is argued that (in-)authenticity is difficult to observe in others. The second article offers a solution to this difficulty in one theory of authenticity. It is proposed that under certain circumstances, it is morally justified to judge that the desires underlying a person's decisions are inauthentic. The third article incorporates this proposition into an already established theory of personal autonomy. It is argued that the resulting conceptualization of autonomy is fruitful for action-guidance in authenticity-related problems in healthcare. The fourth article collects nine cases of possible authenticity-related problems in healthcare. The theory developed in the third article is applied to the problems, when this is allowed by the case-description, to provide guidance with regard to them. It is argued that there is not one universal authenticity-related problem but many different problems, and that there is thus likely not one universal solution to such problems but various particular solutions.

Our aim is to provide a topography of the relevant philosophical terrain with regard to the possible ways in which knowledge can be conceived of as extended. We begin by charting the different types of internalist and externalist proposals within epistemology, and we critically examine the different formulations of the epistemic internalism/externalism debate they lead to. Next, we turn to the internalism/externalism distinction within philosophy of mind and cognitive science. In light of the above dividing lines, we then examine first (...) the extent to which content externalism is compatible with epistemic externalism; second, whether active externalism entails epistemic externalism; and third whether there are varieties of epistemic externalism that are better suited to accommodate active externalism. Finally, we examine whether the combination of epistemic and cognitive externalism is necessary for epistemology and we comment on the potential ramifications of this move for social epistemology and philosophy of science.

Extended cognition theorists argue that cognitive processes constitutively depend on resources that are neither organically composed, nor located inside the bodily boundaries of the agent, provided certain conditions on the integration of those processes into the agent’s cognitive architecture are met. Epistemologists, however, worry that in so far as such cognitively integrated processes are epistemically relevant, agents could thus come to enjoy an untoward explosion of knowledge. This paper develops and defends an approach to cognitive integration—cluster-model functionalism—which finds application in (...) both domains of inquiry, and which meets the challenge posed by putative cases of cognitive or epistemic bloat.

There are a number of competing psychological accounts of the placebo effect, and much of the recent debate centers on the relative importance of classical conditioning and conscious beliefs. In this paper, I discuss apparent problems with these accounts and with?disjunctive? accounts that deny that placebo effects can be given a unified psychological explanation. The fact that some placebo effects seem to be mediated by cognitive states with content that is consciously inaccessible and inferentially isolated from a subject's beliefs motivates (...) an account of the placebo effect in terms of subdoxastic cognitive states. I propose that aliefs, subdoxastic cognitive states that are associative, automatic, and arational, can provide a unified psychological account of the placebo effect. This account also has the potential to illuminate interesting connections to other psychological phenomena. (shrink)

A neo-Aristotelian approach to self-control has dominated both philosophy and the sciences of the mind. This approach endorses three key theses: that self-control is a form of self-regulation aimed at desires that conflict with one’s evaluative judgments, that high trait self-control is continence, which is distinguished from temperance by motivational conflict, and that self-control is broad, in that such resistance can be not only direct but also indirect. There is an obvious tension between and. I argue that the equally obvious (...) resolution of this tension—allowing that self-control does not require occurrent conflicting desires but can instead be aimed at foreseeable conflicting desires—reveals a surprisingly unnoticed tension between and. To resolve this tension, we are forced to either deny that high trait self-control is continence or deny that self-control is broad. If self-control is narrow, recent empirical evidence suggests that it may not be a good candidate for a human excellence concerning self-regulation. Thus, if we want to make room for such an excellence, we may need to deny that high trait self-control is continence. However we resolve these tensions, the Aristotelian status quo regarding self-control cannot stand. (shrink)

In this paper I return to the mid-20th-century debate between Quine and Carnap on the status of metaphysics questions with an eye toward advancing contemporary debates about whether naturalists can coherently undertake substantive metaphysical inquiry. Following Huw Price, I take the debate between Quine and Carnap to hinge, in part, on whether human inquiry is functionally unified. However, unlike Price, I suggest that this question is not best understood as a question about the function(s) of descriptive discourse. This goes along (...) with rejecting a “linguistic conception” of the starting point of metaphysical inquiry, which, although shared by Quine and Carnap, Price gives us no good reason to think is mandatory for naturalists. I sketch two reasons naturalists have to reject a particular manifestation of this linguistic conception in Quine’s work—his criterion of ontological commitment. Finally, I show how these reasons can help us identify the grains of truth in some recent critiques of “mainstream metaphysics of mind.”. (shrink)

According to many virtue ethicists, one of Aristotle’s important achievements was drawing a clear, qualitative distinction between the character traits of temperance and self-control. In an influential series of papers, John McDowell has argued that a clear distinction between temperance and self-control can be maintained only if one claims that, for the virtuous individual, considerations in favor of actions that are contrary to virtue are “silenced.” Some virtue ethicists reject McDowell’s silencing view as offering an implausible or inappropriate picture of (...) human virtue, but they argue that virtue can still be clearly distinguished from self-control by the absence of motivational conflict alone. In this paper, I argue that this criticism of McDowell is at most half right. If the silencing view is false, so that virtue can have a cost and the virtuous person can justifiably feel negative emotions in response to that cost, there is no principled reason why the virtuous person cannot also have motivational conflict. So, if one rejects the silencing view, then one must allow that the distinction between virtue and self-control is at most a matter of degree. (shrink)

The philosophical case for extended cognition is often made with reference to ‘extended-memory cases’ ; though, unfortunately, proponents of the hypothesis of extended cognition as well as their adversaries have failed to appreciate the kinds of epistemological problems extended-memory cases pose for mainstream thinking in the epistemology of memory. It is time to give these problems a closer look. Our plan is as follows: in §1, we argue that an epistemological theory remains compatible with HEC only if its epistemic assessments (...) do not violate what we call ‘the epistemic parity principle’. In §2, we show how the constraint of respecting the epistemic parity principle stands in what appears to be a prima facie intractable tension with mainstream thinking about cases of propositional memory. We then outline and evaluate in §3 several lines of response. (shrink)

Respect for autonomy is a central moral principle in bioethics. The concept of autonomy can be construed in various ways. Under the non-ideal conceptualization proposed by Beauchamp and Childress, everyday choices of generally competent persons are autonomous to the extent that they are intentional and are made with understanding and without controlling influences. It is sometimes suggested that authenticity is important to personal autonomy, so that inauthenticity prevents otherwise autonomous persons from making autonomous decisions. Building from Beauchamp and Childress’s theory, (...) this article develops a non-ideal authenticity-based conceptualization of personal autonomy. Factors that indicate inauthentic decision-making are explicated, and the full concept is defended from three expected objections. The theory is then tested on a paradigm case which has concerned theorists and practitioners for some time, namely the possible inauthenticity of anorexia nervosa patients’ decision-making. It is concluded that the theory seems to be fruitful in analyses of the degree of autonomy of patients’ decision-making, and that it succeeds in providing reliable action-guidance in practical contexts.

While it is widely regarded that intellectual humility is among the intellectual virtues, there is as of yet little consensus on the matter of what possessing and exercising intellectual humility consists in, and how it should be best understood as advancing our epistemic goals. For example, does intellectual humility involve an underestimation of one’s intellectual abilities, or rather, does it require an accurate conception? Is intellectual humility a fundamentally interpersonal/social virtue, or might it be valuable to exercise in isolation? To (...) what extent does intellectual humility demand of us an appreciation of how the success of our inquiries depends on features of our social and physical environment beyond our control? These are just a few of the many questions that are crucial to getting a grip on this intellectual virtue and why we might aspire to cultivate it. Furthermore, and apart from the nature and value of humility, it is worthwhile to consider how this notion, properly understood, might have import for other philosophical debates, including those about (for example) scepticism, assertion, epistemic individualism and anti-individualism, and the philosophy of education. This special issue brings together a range of different philosophical perspectives on these and related questions to do with intellectual humility with an aim to contributing to this important and timely topic.

According to some critics of liberal individualism, it is fundamentally problematic that individualists focus on rights instead of community and on decision-making processes instead of substantial goods. Among other things, it is claimed that liberal individualism therefore fails to provide meaning to people’s lives. The view has recently gained momentum as it has been incorporated in novel conservative and nationalist arguments. This article presents an individualist theory of meaning in response to a recent nationalist reiteration of the critique. The theory (...) is that a continuous pursuit of self-endorsement by a perfected, liberal, version of oneself provides purpose and direction in life. This allows the individual to be the ultimate arbiter in meaning-building matters, as the theory locates meaning in the individual’s decision-making processes rather than in factors external to her. The theory acknowledges the interdependence of human beings but remains loyal to the view that the value of the individual generally trumps competing values, such as that of the collective. (shrink)

Much of contemporary research ethics was developed in the latter half of the twentieth century as a response to the unethical treatment of human beings in biomedical research. Research ethical considerations have subsequently been extended to cover topics in the sciences and technology such as data handling, precautionary measures, engineering codes of conduct, and more. However, moral issues in the humanities have gained less attention from research ethicists. This article proposes an ethical principle for reading for research purposes: Respect the (...) author.

A gas in a box is perhaps the most important model system studied in thermodynamics and statistical mechanics. Usually, studies focus on the gas, whereas the box merely serves as an idealized confinement. The present article focuses on the box as the central object and develops a thermodynamic theory by treating the geometric degrees of freedom of the box as the degrees of freedom of a thermodynamic system. Applying standard mathematical methods to the thermody- namics of an empty box allows (...) equations with the same structure as those of cosmology and classical and quantum mechanics to be derived. The simple model system of an empty box is shown to have interesting connections to classical mechanics, special relativity, and quantum field theory. (shrink)

Jesper Kallestrup has provided an insightful response to our paper, “Epistemic Structure in Non-Summative Social Knowledge”. Kallestrup identifies some important issues pertaining to our non-summative, non-supervenient account of group knowledge which we did not address in our original paper. Here, we develop our view further in light of Kallestrup’s helpful reply.

A new way to transpose the virtue epistemologist’s ‘knowledge = apt belief’ template to the collective level, as a thesis about group knowledge, is developed. In particular, it is shown how specifically judgmental belief can be realised at the collective level in a way that is structurally analogous, on a telic theory of epistemic normativity (e.g., Sosa 2020), to how it is realised at the individual level—viz., through a (collective) intentional attempt to get it right aptly (whether p) by alethically (...) affirming that p. An advantage of the proposal developed is that it is shown to be compatible with competing views—viz., joint acceptance accounts and social-distributive accounts—of how group members must interact in order to materially realise a group belief. I conclude by showing how the proposed judgment-focused collective (telic) virtue epistemology has important advantages over a rival version of collective virtue epistemology defended in recent work by Jesper Kallestrup (2016).

In 1992, Bengt Hägglund put forward a thesis according to which a codex in his possession is based on material Johannes Rudbeckius (1581–1646) authored in 1611, maintaining that the codex gives us information about Rudbeckius's lectures on _loci theologici_ in Uppsala during the years 1611–1613 and that it reveals to us characteristic features of Rudbeckius's thinking about dogmatics. Hägglund published the codex in 2001. I point out, first, weaknesses in Hägglund's argumentation. Second, I present indirect evidence against his thesis employing (...) the two series of Rudbeckius's published dissertations on dogmatics (1611–1613, 1620–1644) and his own comments about his lectures. Third, I indicate that three parts of the codex that are particularly important for Hägglund's argumentation stem from other authors: the introductory part on the nature of theo­logy, as well as the chapter on _locus de ecclesia_, have their origin in Jesper Brochmand's _Universae theologiae systema_ (1633), while the conclusion is taken from a dissertation that Balthasar Meisner published in 1614. The codex does not allow us to access a work Rudbeckius would have authored in 1611: it contains too many parts he cannot have authored then. In particular, the introduction and the conclusion of the codex do not tell us anything about Rudbeckius's characteristic thoughts on dogmatics. Hägglund's main reason for thinking that the codex is a transcript of Rudbeckius's work from 1611 is a date mentioned at the end of locus of the church. As it happens, this locus is borrowed from Brochmand, not from Rudbeckius. (shrink)

The evidential value of moral intuitions has been challenged by psychological work showing that the intuitions of ordinary people are affected by distorting factors. One reply to this challenge, the expertise defence, claims that training in philosophical thinking confers enhanced reliability on the intuitions of professional philosophers. This defence is often expressed through analogy: since we do not allow doubts about folk judgments in domains like mathematics or physics to undermine the plausibility of judgments by experts in these domains, we (...) also should not do so in philosophy. In this paper I clarify the logic of the analogy strategy, and defend it against recent challenges by Jesper Ryberg. The discussion exposes an interesting divide: while Ryberg’s challenges may weaken analogies between morality and domains like mathematics, they do not affect analogies to other domains, such as physics. I conclude that the expertise defence can be supported by analogical means, though care is required in selecting an appropriate analog. I discuss implications of this conclusion for the expertise defence debate and for study of the moral domain itself. (shrink)

In a series of papers, Jesper Kallestrup and Duncan Pritchard argue that the thesis that knowledge is a cognitive success because of cognitive ability (robust virtue epistemology) is incompatible with the idea that whether or not an agent’s true belief amounts to knowledge can significantly depend upon factors beyond her cognitive agency (epistemic dependence). In particular, certain purely modal facts seem to preclude knowledge, while the contribution of other agents’ cognitive abilities seems to enable it. Kallestrup and Pritchard’s arguments (...) are targeted against views that hold that all it takes to manifest one’s cognitive agency is to properly exercise one’s belief-forming abilities. I offer an account of the notion of cognitive ability according to which our epistemic resources are not exhausted by abilities to produce true beliefs as outputs, but also include dispositions to stop belief-formation when actual or modal circumstances are not suitable for it (precautionary cognitive abilities). Knowledge, I argue, can be accordingly conceived as a cognitive success that is also due to the latter. The resulting version of robust virtue epistemology helps explain how purely modal facts as well as other agents’ cognitive abilities may have a bearing on the manifestation of one’s cognitive agency, which shows in turn that robust virtue epistemology and epistemic dependence are not incompatible after all.

In a recent article in Respublica, Jesper Ryberg argues that CCTV can be compared to a little old lady gazing out onto the street below. This article takes issue with the claim that government surveillance can be justified in this manner. Governments have powers and responsibilities that little old ladies lack. Even if CCTV is effective at preventing crime, there may be less intrusive ways of doing so. People have a variety of legitimate interests in privacy, and protection for (...) these is important to their status as free and equal citizens. Consequently, though necessary, effectiveness is insufficient to justify CCTV in a democracy. (shrink)

In this paper, I respond to an objection raised by Duncan Pritchard and Jesper Kallestrup against virtue epistemology. In particular, they argue that the virtue epistemologist must either deny that S knows that p only if S believes that p because of S’s virtuous operation or deny that intuitive cases of testimonial knowledge. Their dilemma has roots in the apparent ease by which we obtain testimonial knowledge and, thus, how the virtue epistemologist can explain such knowledge in a way (...) that both preserves testimonial knowledge and grounds it in one’s virtues. I argue that the virtue epistemologist has a way to accomplish both tasks if we take epistemic trust to be an intellectual virtue. I briefly discuss what such trust must look like and then apply it to the dilemma at hand: showing that a key intellectual virtue plausibly operates in cases of testimonial knowledge and/or belief.

The concept of information and its relation to biosemiotics is a major area of contention among biosemioticians. Biosemioticians influenced by von Uexküll, Sebeok, Bateson and Peirce are critical of the way the concept as developed in information science has been applied to biology, while others believe that for biosemiotics to gain acceptance it will have to embrace information science and distance biosemiotics from Peirce’s philosophical work. Here I will defend the influence of Peirce on biosemiotics, arguing that information science and (...) biosemiotics as these were originally formulated are radically opposed research traditions. Failure to appreciate this will undermine the challenge of biosemiotics and other anti-reductionist traditions to mainstream science with its reductionist ambition to explain everything through physics. However, for this challenge to be successful, it will be necessary to respond to criticisms of Peircian ideas, jettisoning ideas that are no longer defensible and integrating ideas allied to his anti-reductionist agenda. Here I will argue that the natural philosophy of Gilbert Simondon, offering a searching critique of the application of the new concept of information and cybernetics to the life and human sciences, provides the means to defend and advance Peirce’s core ideas and thereby defend post-reductionist biosemiotics.

The file on this site provides the slides for a lecture given in Hangzhou in May 2018, and the lecture itself is available at the URL beginning 'sms' in the set of links provided in connection with this item. -/- It is commonly assumed that regular physics underpins biology. Here it is proposed, in a synthesis of ideas by various authors, that in reality structures and mechanisms of a biological character underpin the world studied by physicists, in principle supplying detail (...) in the domain that according to regular physics is of an indeterminate character. In regular physics mathematical equations are primary, but this constraint leads to problems with reconciling theory and reality. Biology on the other hand typically does not characterise nature in quantitative terms, instead investigating in detail important complex interrelationships between parts, leading to an understanding of the systems concerned that is in some respects beyond that which prevails in regular physics. It makes contact with quantum physics in various ways, for example in that both involve interactions between observer and observed, an insight that explains what is special about processes involving observation, justifying in the quantum physics context the replacement of the unphysical many-worlds picture by one involving collapse. The link with biology furthermore clarifies Wheeler’s suggestion that a multiplicity of observations can lead to the ‘fabrication of form’, including the insight that this process depends on very specific ‘structures with power’ related to the 'semiotic scaffolding' of the application of sign theory to biology known as biosemiotics. -/- The observer-observed 'circle' of Wheeler and Yardley is a special case of a more general phenomenon, oppositional dynamics, related to the 'intra-action' of Barad's Agential Realism, involving cooperating systems such as mind and matter, abstract and concrete, observer and observed, that preserve their identities while interacting with one another in such a way as to act as a unit. A third system may also be involved, the mediating system of Peirce linking the two together. Such a situation of changing connections and separations may plausibly lead in the future to an understanding of how complex systems are able to evolve to produce 'life, the universe and everything'. -/- (Added 1 July 2018) The general structure proposed here as an alternative to a mathematics-based physics can be usefully characterised by relating it to different disciplines and the specialised concepts utilised therein. In theoretical physics, the test for the correctness of a theory typically involves numerical predictions, corresponding to which theories are expressed in terms of equations, that is to say assertions that two quantities have identical values. Equations have a lesser significance in biology which typically talks in terms of functional mechanisms, dependent for example on details of chemistry and concepts such as genes, natural selection, signals and geometrical or topologically motivated concepts such as the interconnections between systems and the unfolding of DNA. Biosemiotics adds to this the concept of signs and their interpretation, implying novel concepts such as semiotic scaffolding and the semiosphere, code duality, and appreciation of the different types of signs, including symbols and their capacity for abstraction and use in language systems. Circular Theory adds to this picture, as do the ideas of Barad, considerations such as the idea of oppositional dynamics. The proposals in this lecture can be regarded as the idea that concepts such as those deriving from biosemiotics have more general applicability than just conventional biology and may apply, in some circumstances, to nonlinear systems generally, including the domain new to science hypothesised to underlie the phenomena of present-day physics. -/- The task then has to be to restore the mathematical aspect presumed, in this picture, not to be fundamental as it is in conventional theory. Deacon has invoked a complex sequence of evolutionary steps to account for the emergence over time of human language systems, and correspondingly mathematical behaviour can be subsumed under the general evolutionary mechanisms of biosemiotics (cf. also the proposals of Davis and Hersh regarding the nature of mathematics), so that the mathematical behaviour of physical systems is consistent with the proposed scheme. In conclusion, it is suggested that theoretical physicists should cease expecting to find some universal mathematical ‘theory of everything’, and focus instead on understanding in more detail complex systems exhibiting behaviour of a biological character, extending existing understanding. This may in time provide a more fruitful understanding of the natural world than does the regular approach. The essential concepts have an observational basis from both biology and the little-known discipline of cymatics (a discipline concerned with the remarkable patterns that specific waveforms can give rise to), while again computer simulations also offer promise in providing insight into the complex behaviours involved in the above proposals. -/- References -/- Jesper Hoffmeyer, Semiotic Scaffolding of Living Systems.
