This article uses sim-max games to model perceptual categorization with the goal of answering the following question: To what degree should we expect the perceptual categories of biological actors to track properties of the world around them? I argue that an analysis of these games suggests that the relationship between real-world structure and evolved perceptual categories is mediated by successful action in the sense that organisms evolve to categorize together states of nature for which similar actions lead to similar results. (...) This conclusion indicates that both strongly realist and strongly antirealist views about perceptual categories are too simple. (shrink)

This paper focuses on 3 features of Freyenhagen's Aristotelian version of Adorno. (a) It challenges the strict negativism Freyenhagen finds in Adorno. If we have morally relevant interests in ourselves, it is implicit that we have a standard by which to understand what is both good and bad for us (our interests). Because strict negativism operates without reference to what is good, it seems to be detached from real interests too. Torture, it is argued, is, among other things, a violation (...) of those interests. (b) Freyenhagen identifies the “impulse” in Adorno as an untutored yet moral reaction to morally demanding situations. The plausibility of this primitivism and its compatibility with Adorno's general worries about immediacy are considered. (c) The disruptive character of Adorno's version of the categorical imperative, its willingness to complicate action through wholesale reflection on the norms of what we are committing ourselves to, is set in contrast with Freyenhagen's Aristotelian claim that certain notions, such as “humanity,” cannot be intelligibly questioned.

Biologists and philosophers of biology have argued that learning rules that do not lead organisms to play evolutionarily stable strategies (ESSes) in games will not be stable and thus not evolutionarily successful. This claim, however, stands at odds with the fact that learning generalization---a behavior that cannot lead to ESSes when modeled in games---is observed throughout the animal kingdom. In this paper, I use learning generalization to illustrate how previous analyses of the evolution of learning have gone wrong. It has (...) been widely argued that the function of learning generalization is to allow for swift learning about novel stimuli. I show that in evolutionary game theoretic models learning generalization, despite leading to suboptimal behavior, can indeed speed learning. I further observe that previous analyses of the evolution of learning ignored the short term success of learning rules. If one drops this assumption, I argue, it can be shown that learning generalization will be expected to evolve in these models. I also use this analysis to show how ESS methodology can be misleading, and to reject previous justifications about ESS play derived from analyses of learning. (shrink)

This paper criticizes the assumptions behind Robert Brandom’s reading of Hegel’s Phenomenology, contending that Hegel’s concern with the rational structure of experience, his valorization of reflection over ordinary experience and his idea of the necessit y of progress in knowledge cannot be accommodated within the framework of semantic pragmatism. The central contentions are that Brandom’s pragmatism never comes to terms with Hegel’s idea of truth as a result, leading to a historicist distortion, and also that Brandom’s failure to deal with (...) Hegel’s distinction between natural consciousness and the phenomenological observer collapses Hegel’s phenomenology into a philosophy restricted to the level of natural consciousness. (shrink)

This paper critically evaluates what it identifies as ‘the institutional theory of freedom’ developed within recent neo-Hegelian philosophy. While acknowledging the gains made against the Kantian theory of autonomy as detachment it is argued that the institutional theory ultimately undermines the very meaning of practical agency. By tying agency to institutionally sustained recognition it effectively excludes the exercise of practical reason geared toward emancipation from a settled normative order. Adorno's notion of autonomy as resistance is enlisted to develop an account (...) of practical reason that is neither institutionally constrained nor without appropriate consideration of the historical location of the practical agent.

Adorno and Heidegger are frequently aligned because of apparent similarities in their critiques of modern epistemology. This alignment fails, however, to appreciate the substantial differences in the philosophical presuppositions that inform those very critiques. I distinguish Adorno's negative dialectic from Heidegger's fundamental ontology under the respective designations of critical versus phenomenological forms of transcendental philosophy. I argue that only by understanding Adorno's negative dialectic as a revised version of epistemology (namely a dialectical epistemology, committed to subject-object and transcendental argument) can (...) we make sense of, first, the profound differences between Adorno and Heidegger on the question of epistemology and, second, the philosophical motivations behind Adorno's trenchant rejection of Heidegger. Key Words: being-in-the-world • - dialectics • - empiricism • - epistemology • - idealism • - identity • - immediacy • - irrationalism • - mediation • - project • - subject • -object • - transcendental.

Collaboration is increasingly popular across academia. Collaborative work raises certain ethical questions, however. How will the fruits of collaboration be divided? How will the work for the collaborative project be split? In this paper, we consider the following question in particular. Are there ways in which these divisions systematically disadvantage certain groups? -/- We use evolutionary game theoretic models to address this question. First, we discuss results from O'Connor and Bruner (unpublished). In this paper, we show that underrepresented groups in (...) academia can be disadvantaged in such situations by dint of their small numbers. Second, we present novel results exploring how the hierarchical structure of academia can lead to bargaining disadvantage. We investigate models where one actor has a higher baseline of academic success, less to lose if collaboration goes south, or greater rewards for non-collaborative work. We show that in these situations, the less powerful partner is disadvantaged in bargaining over collaboration. (shrink)

The core argument of the paper is that the modern philosophical notion of self-constitution is directed against the prospect of human beings dissolving into idleness. Arguments for self-constitution are marked by non-philosophical presuppositions about the value of usefulness. Those arguments also assume a particular conception of superior experience as conscious integration of a person’s actions within an identifiable set of chosen commitments. Exploring particular arguments by Hegel, Kant, Korsgaard and Frankfurt the paper claims that those arguments are problematic in the (...) various ways in which they suppose usefulness and explicitly or implicitly take extra-philosophical views of idleness.

In this paper we critically examine and seek to extend Philip Kitcher’s Ethical Project to weave together a distinctive naturalistic conception of how ethics came to occupy the place it does in our lives and how the existing ethical project should be revised and extended into the future. Although we endorse his insight that ethical progress is better conceived of as the improvement of an existing state than an incremental approach towards a fixed endpoint, we nonetheless go on to argue (...) that the metaethical apparatus Kitcher constructs around this creative metaethical proposal simply cannot do the work that he demands of it. The prospect of fundamental conflict between different functions of the ethical project requires Kitcher to appeal to a particular normative stance in order to judge specific changes in the ethical project to be genuinely progressive, and we argue that the virtues of continuity and coherence to which he appeals can only specify rather than justify the normative stance he favors. We conclude by suggesting an alternative approach for ethical naturalists that seems to us ultimately more promising than Kitcher’s own. (shrink)

In this paper we use an experimental approach to investigate how linguistic conventions can emerge in a society without explicit agreement. As a starting point we consider the signaling game introduced by Lewis. We find that in experimental settings, small groups can quickly develop conventions of signal meaning in these games. We also investigate versions of the game where the theoretical literature indicates that meaning will be less likely to arise—when there are more than two states for actors to transfer (...) meaning about and when some states are more likely than others. In these cases, we find that actors are less likely to arrive at strategies where signals have clear conventional meaning. We conclude with a proposal for extending the use of the methodology of experimental economics in experimental philosophy. (shrink)

This is a critical theoretical investigation of Hubert Dreyfus’ ‘phenomenology of everyday expertise’ (PEE). Operating mainly through the critical perspective of the ‘emancipatory interest’ the article takes issue with the contention that when engaged in expert action human beings are in non-deliberative, reason-free absorption. The claim of PEE that absorbed actions are not amenable to reconstruction places those actions outside the space of reasons. The question of acting under the wrong reasons – the question upon which the emancipatory interest rests (...) – is thereby rendered groundless. A further difficulty for the emancipatory interest is the elimination by PEE of reflective agency. Framing expert action as perception- and affordance-driven, PEE diminishes practical reasoning. Furthermore, it understands freedom – consistently with its notion of action as affordance – as primarily the capacity of human beings to submit themselves to processes rather than to step back reflectively from them. Several criticisms of the philosophical delimitations created by methodology of PEE – phenomenology – are also developed. (shrink)

Diversity of practice is widely recognized as crucial to scientific progress. If all scientists perform the same tests in their research, they might miss important insights that other tests would yield. If all scientists adhere to the same theories, they might fail to explore other options which, in turn, might be superior. But the mechanisms that lead to this sort of diversity can also generate epistemic harms when scientific communities fail to reach swift consensus on successful theories. In this paper, (...) we draw on extant literature using network models to investigate diversity in science. We evaluate different mechanisms from the modeling literature that can promote transient diversity of practice, keeping in mind ethical and practical constraints posed by real epistemic communities. We ask: what are the best ways to promote an appropriate amount of diversity of practice in scientific communities? (shrink)

Given its centrality to the intellectual thought processes through which the great structures of logic, nature, and spirit are unfolded it is clear that mediation is vital to the very possibility of Hegel’s encyclopaedic philosophy. Yet Hegel gives little specific explanation of the concept of mediation. Surprisingly, it has been the subject of even less attention by scholars of Hegel. Nevertheless it is casually used in discussions of Hegel and post- Hegelian philosophy as though its meaning were simple and straightforward. (...) In these discussions mediation is the thesis that meanings are not atomic in that the independence of something is inseparable from its relation to something else. Hence being is mediated by nothing, the particular by the universal, the individual by society. But does Hegel ever explain mediation in a way which justifies such use of the concept? The same easy employment of mediation is found in Theodor Adorno whose works are replete with the use of this concept and, indeed, acknowledgements of its Hegelian origin. But the concept of mediation in Adorno’s negative dialectic is operative in an entirely different context from that of Hegel. How, it might be asked, can a concept be so adaptable? I want to argue that mediation is, in fact, an equivocal term which in both Hegel and Adorno covers a variety of entirely different conceptual relations. Furthermore, as propounded by both Hegel and Adorno it lacks the rigour which could allow the particular conclusions which the concept allegedly facilitates. (shrink)

The central concern of this paper is to explore the efforts of Schiller's post-Kantian idealism and Marcuse's critical theory to develop a new conception of free human experience. That conception is built on the notion of play. Play is said to combine the human capacities for physical pleasure and reason, capacities which the modern world has dualized. Analysis of their respective accounts of play reveals its ambivalent form in the work of both philosophers. Play supports the ideal of ‘freedom from (...) necessity’, understood as a release from all external constraint. But it also appears to serve as a model for ‘freedom as a higher necessity’. In the case of Schiller, the ambivalence encompasses idle play and an obligation to make ourselves worthy of freedom. For Marcuse, play represents a kind of libidinal idleness while also underpinning a non-alienated conception of labour. (shrink)

In an era of digital revolution, artificial intelligence, big data and augmented reality, technology has shifted from being a tool of communication to a primary medium of experience and sociality. Some of the most basic human capacities are increasingly being outsourced to machines and we increasingly experience and interpret the world through digital interfaces, with machines becoming ever more ‘social’ beings. Social interaction and human perception are being reshaped in unprecedented ways. This book explores this technologisation of the social and (...) the attendant penetration of permanent liminality into those aspects of the lifeworld where individuals had previously sought some kind of stability and meaning. Through a historical and anthropological examination of this phenomenon, it problematises the underlying logic of limitless technological expansion and our increasing inability to imagine either ourselves or our world in other than technological terms. Drawing on a variety of concepts from political anthropology, including liminality, the trickster, imitation, schismogenesis, participation, and the void, it interrogates the contemporary technological revolution in a manner that will be of interest to sociologists, social and anthropological theorists and scholars of science and technology studies with interests in the digital transformation of social life. -/- Table of Contents -/- Introduction: The Technologisation of the Social: A 21st-Century Megamachine?

This paper contends that Kant’s argument in the Refutation of Idealism section of the Critique of Pure Reason misses a step which allows Kant to move illicitly from inner experience to outer objects. The argument for persistent outer objects does not comprehensively address the skeptic’s doubts as it leaves room for the question about the necessary connection between representations and outer objects. A second fundamental issue is the ability of transcendental idealism to deliver the account of outer objects, as required (...) by the Refutation of Idealism itself. (shrink)

We present an original emergent individuals view of human persons, on which persons are substantial biological unities that exemplify metaphysically emergent mental states. We argue that this view allows for a coherent model of identity-preserving resurrection from the dead consistent with orthodox Christian doctrine, one that improves upon alternatives accounts recently proposed by a number of authors. Our model is a variant of the “falling elevator” model advanced by Dean Zimmerman that, unlike Zimmerman’s, does not require a closest continuer account (...) of personal identity. We end by raising some remaining theological concerns. (shrink)

Review of Peter Godfrey-Smith's Philosophy of Biology.

The beginning of the 21st century has seen the renewed use of aesthetics as a critical and interpretive method within various discursive spheres. Particularly, and unsurprisingly, this move has been most pronounced in the discursive systems of philosophy and the artworld. It is to this more specific re-discovery that the authors in this journal address their arguments.

This chapter is a critical discussion of the third chapter of Tim O'Connor's *Theism and Ultimate Explanation*. In this chapter, O'Connor advances the 'existence stage' of his cosmological argument from contingency. I argue that naturalists have good reason to think that on each of the live hypotheses -- infinite regress, brute contingency, brute necessity -- naturalism is preferable to theism.

Timothy O’Connor has recently defended a version of libertarianism that has significant advantages over similar accounts. One of these is an argument that secures indeterminism on the basis of an argument that shows how causal determinism threatens agency in virtue of the nature of the causal relation involved in free acts. In this paper, I argue that while it does turn out that free acts are not causally determined on O’Connor’s view, this fact is merely stipulative and the (...) argument that he presents for this conclusion begs the question.

Žižek has argued in his books on Christianity and modernity that institutional Catholic Christianity has placed its members in a double bind by insisting on belief in a nonexistent God of Being. The laws of this God of the Symbolic are perverse in that they impose impossible requirements on all believers. By the mid-twentieth century, however, Catholicism was experiencing the revolutionary reforms of the Second Vatican Council. Dogmatic Law at this time gave way to a renewed emphasis on the community (...) of love associated in early Christianity with the Holy Spirit. This God of the Real is inherently Trinitarian: God-Father-Thing, Spirit as community of believers, and Christ as the imaginary Real gap between them. The American gothic writer Flannery O’Connor in her short story “A Temple of the Holy Ghost” provides a meditation on this Real Trinity. In O’Connor’s story a hermaphroditic circus freak becomes an emblem of the deadlock of sexual difference and a monstrous Christ-figure in the Žižekian sense. Its place is theologically incoherent and represents the passion for the Real emerging out of the perverse situation of mid-century Catholic orthodoxy. (shrink)

Daniel O’Shiel recently identified four categories of virtuality, which he terms “real virtualities”, that are perpetually present in human perception. These virtual horizons (Self, World, Others, and Values) continuously structure our experience without themselves being directly experienced. This essay argues that O’Shiel’s four categories of the virtual correspond strongly to the concept of the Fourfold found in the writings of the later Heidegger, and that Heidegger’s Fourfold can be fruitfully understood as a phenomenological framework of the virtual.

According to our interpretation, Σῴζειν τὰ φαινóμενα : Essai sur la notion de théorie physique pursues two intricately intertwined objectives. Primarily, it aims to establish the historical significance of Duhemian phenomenalism — the accuracy of which had previously been established in La Théorie Physique : son Objet et sa Structure — firstly, by positioning it within a millenary tradition and, secondly, by examining the conse­quences, both positive and negative, that subsequently arose from the various ways of comprehending the idea of (...) physical theory. Secondarily, it proffers a novel interpretation of the rationale behind the Galileo affair, from a point of view which is both philosophical (that of the Duhemian epistemology as it had already been developed in The Aim and Structure of Physical Theory) and historical (that of the lessons resulting from historical considerations in To Save the Phenomena). This article is dedicated to establishing the existence of the first goal by examining, firstly, whether or not it had actually been sought out by Duhem himself, and, secondly, whether or not he believed he had achieved it.

In this paper, we engage in dialogue with Jonathan Pugh, Hannah Maslen, and Julian Savulescu about how to best interpret the potential impacts of deep brain stimulation on the self. We consider whether ordinary people’s convictions about the true self should be interpreted in essentialist or existentialist ways. Like Pugh et al., we argue that it is useful to understand the notion of the true self as having both essentialist and existentialist components. We also consider two ideas from existentialist philosophy (...) – Jean-Paul Sartre and Simone de Beauvoir’s ideas about “bad faith” and “ambiguity” – to argue that there can be value to patients in regarding themselves as having a certain amount of freedom to choose what aspects of themselves should be considered representative of their true selves. Lastly, we consider the case of an anorexia nervosa-patient who shifts between conflicting mind-sets. We argue that mind-sets in which it is easier for the patient and his or her family to share values can plausibly be considered to be more representative of the patient’s true self, if this promotes a well-functioning relationship between the patient and the family. However, we also argue that families are well-advised to give patients room to figure out what such shared values mean to them, since it can be alienating for patients if they feel that others try to impose values on them from the outside.

Our thesis is that proprioception is not a sixth sense distinct from the sense of touch, but a part of that tactile (or haptic) sense. The tactile sense is defined as the sense whose direct intentional objects are macroscopic mechanical properties. We first argue (against D. Armstrong, 1962; B. O'Shaughnessy 1989, 1995, 1998 and M. Martin, 1992, 1993,1995) that the two following claims are incompatible : (i) proprioception is a sense distinct from touch; (ii) touch is a bipolar modality, that (...) intrinsically has both a subjective-bodily pole and objective pole. We then argue that the bipolarity of touch should be preferred over the introduction of a sui generis sense of the body. We try to revive Aristotle suggestion according to which the body is the tactile medium (like the air for sight). Since this medium is constantly changing its shape, we need some specific channel of information about its state : proprioception, functionally defined, is that part of touch which informs us about the state of this changing tactile medium. Though muscular and articular receptors are usually dedicated to inform us about the mechanical properties of the tactile media, and the skin receptors about the mechanical properties of the tactile objects, this is not essentially so. In weighting or wielding experiments we access the weight of external objects even when skin sensitivity is absent; in prosthetic touch, the skin receptors play the role usually assigned to muscle and articular receptors, namely to inform us about the mechanical state of the tactile medium. So proprioception, anatomically defined, can play both the role of informing us about the tactile medium, or about the tactile objects. That other sensory modalities also rely on proprioceptive information should be understood in terms of cross-modal dependencies: of sight, hearing, smell, taste...on touch. (shrink)

Of all the terms Jean Améry might have chosen to explain the deepest effects of torture, the one he selected was world. To be tortured was to lose trust in the world, to become incapable of feeling at home in the world. In July 1943, Améry was arrested by the Gestapo in Belgium and tortured by the SS at the former fortress of Breendonk. With the first blow from the torturers, he famously wrote, one loses trust in the world. (...) With that blow, one can no l onger be certain that “by reason of written or unwritten social contracts the other person will spare me — and more precisely stated, that he will respect my physical, and with it also my metaphysical, being.” In a vault inside the fortress, beyond the reach of anyone who might help — a wife, a mother, a brother, a friend — it turned out that all social contracts had been broken and torture was possible. His attackers had no respect for him, and no-one else could or would help. (shrink)

O termo “cogito” designa de modo genérico e impreciso um argumento que Descartes propõe em diversos momentos de sua obra. De um modo geral, os comentadores, tal como o fizeram os interlocutores contemporâneos ao autor, consideram que a expressão “penso, logo existo” (cogito ergo sum), ausente das Meditações Metafísicas, resume adequadamente este argumento único e procuram esclarecê-lo ou criticá-lo, nem sempre levando em consideração as diferentes formulações que recebe e os diferentes contextos em que ocorre. Meu objetivo neste texto é (...) simplesmente analisar o quarto parágrafo da Segunda Meditação (AT VII, 24-25; IX-1,19), no qual ele supostamente apresenta este mesmo argumento sem empregar a famosa expressão. Das muitas, diversas e relevantes questões filosóficas que este argumento suscita, gostaria de me concentrar em investigar se ele pode ser reconstruído sem que seja necessário introduzir – como uma premissa não justificada – a concepção do pensamento como sendo essencialmente consciência de si e, portanto, como envolvendo - por definição, a auto-referência imediata e incorrigível do sujeito a si mesmo. Gostaria de poder mostrar que o argumento não apenas independe dessa concepção como, além disso, conduz a essa concepção; todavia, somente o primeiro passo em direção a esta interpretação será dado neste artigo. Quanto à expressão “penso, logo existo”, minha hipótese é que, embora ausente do texto, ela, de fato, resume o sentido geral da posição cartesiana. Sua ausência explica-se pelo fato de que Descartes pretende apresentar nas Meditações a versão mais completa de seu argumento e a passagem que será aqui analisada constitui, na realidade, apenas uma primeira etapa dessa versão. A análise e a reconstrução que serão propostas supõe que o argumento apresentado no parágrafo 4 deva ser compreendido, como propõe H. G. Frankfurt, como composto de quatro etapas, cujo sentido depende do contexto argumentativo mais amplo no qual estão inseridas, como observou Jean-Claude Pariente, em seu artigo sobre o cogito nas Meditações Metafísicas. Nesse sentido, a estrutura do presente artigo seguirá essas etapas. (shrink)
