For countable structures U and B, let $\mathfrak{U}\overset{\alpha}{\rightarrow}\mathfrak{B}$ abbreviate the statement that every Σ0 α (Lω1,ω) sentence true in U also holds in B. One can define a back and forth game between the structures U and B that determines whether $\mathfrak{U}\overset{\alpha}{\rightarrow}\mathfrak{B}$ . We verify that if θ is an Lω,ω sentence that is not equivalent to any Lω,ω Σ0 n sentence, then there are countably infinite models U and B such that $\mathfrak{U} \vDash \theta, \mathfrak{B} \vDash \neg \theta$ , (...) and $\mathfrak{U}\overset{n}{\rightarrow}\mathfrak{B}$ . For countable languages L there is a natural way to view L structures with universe ω as a topological space, XL. Let [U] = {B ∈ XL∣B ≅ U} denote the isomorphism class of U. Let U and B be countably infinite nonisomorphic L structures, and let $C \subseteq \omega^\omega$ be any Π0 α subset. Our main result states that if $\mathfrak{U}\overset{\alpha}{\rightarrow}\mathfrak{B}$ , then there is a continuous function f: ωω → XL with the property that $x \in C \Rightarrow f(x) \in \lbrack\mathfrak{U}\rbrack$ and $x \notin C \Rightarrow f(x) \in \lbrack\mathfrak{B}\rbrack$ . In fact, for α ≤ 3, the continuous function f can be defined from the $\overset{\alpha}{\rightarrow}$ relation. (shrink)

'By identifying the extent to which Aristotle's thinking about ethics was shaped by notions drawn from the crafts Angier has thrown new light on a surprising number of topics and has deepened our understanding of tensions within Aristotle's thought. It is by now a rare achievement to have said something new, true and important about Aristotle.' -- Alasdair MacIntyre, Emeritus Professor of Philosophy, University of Notre Dame, USA.

There is an overlooked similarity between three classic accounts of the conditions of object experience from three distinct disciplines. Sociology: the “inversion” that accompanies discovery in the natural sciences, as local causes of effects are reattributed to an observed object. Psychology: the “externalization” that accompanies mastery of a visual–tactile sensory substitution interface, as tactile sensations of the proximal interface are transformed into vision-like experience of a distal object. Biology: the “projection” that brings forth an animal’s Umwelt, as impressions on its (...) body’s sensory surfaces are reconfigured into perception of an external object. This similarity between the effects of scientific practice and interface-use on the one hand, and of sensorimotor interaction on the other, becomes intelligible once we accept that skillful engagement with instruments and interfaces constitutes a socio-material augmentation of our basic perceptual capacity. This enactive interpretation stands in contrast to anti-realism about science associated with constructivist interpretations of these three phenomena, which are motivated by viewing them as the internal mental construction of the experienced object. Instead, it favors a participatory realism: the sensorimotor basis of perceptual experience loops not only through our body, but also through the external world. This allows us to conceive of object experience in relational terms, i.e., as one or more subjects directly engaging with the world. Consequently, we can appreciate scientific observation in its full complexity: it is a socio-materially augmented process of becoming acquainted with the observed object that—like tool-use and perceiving more generally—is irreducibly self, other-, and world-involving.

This article poses a challenge to Schurz’s proposed metainductive justification of induction. It is argued that Schurz’s argument requires a notion of optimality that can deal with an expanding pool of prediction strategies.

Empirical studies have suggested that language-capable robots have the persuasive power to shape the shared moral norms based on how they respond to human norm violations. This persuasive power presents cause for concern, but also the opportunity to persuade humans to cultivate their own moral development. We argue that a truly socially integrated and morally competent robot must be willing to communicate its objection to humans’ proposed violations of shared norms by using strategies such as blame-laden rebukes, even if doing (...) so may violate other standing norms, such as politeness. By drawing on Confucian ethics, we argue that a robot’s ability to employ blame-laden moral rebukes to respond to unethical human requests is crucial for cultivating a flourishing “moral ecology” of human–robot interaction. Such positive moral ecology allows human teammates to develop their own moral reflection skills and grow their own virtues. Furthermore, this ability can and should be considered as one criterion for assessing artificial moral agency. Finally, this paper discusses potential implications of the Confucian theories for designing socially integrated and morally competent robots. (shrink)

Deacon develops a minimal model of a nonparasitic virus to explore how nucleotide sequences came to be characterized by a code-like informational at the origin of life. The model serves to problematize the concept of biological normativity because it highlights two common yet typically implicit assumptions: that life could consist as an inert form, were it not for extrinsic sources of physical instability, and that life could have originated as a singular self-contained individual. I propose that the origin of life, (...) the genetic code, and biological normativity more generally, lead us to reject this passive individualism. (shrink)

It is generally held that doctors and researchers have an obligation to obtain informed consent. Over time there has been a move in relation to this obligation from a requirement to disclose information to a requirement to ensure that that information is understood. Whilst this change has been resisted, in this article I argue that both sides on this matter are mistaken. When investigating what information is needed for consent to be informed we might be trying to determine what information (...) a person would need in order to consent at all, or we might be trying to determine what information a person needs in order to make an informed choice about whether or not to consent. I argue that the obligation to ensure understanding only applies to information generated by the first type of enquiry; but that much of the information generally thought necessary in order for consent to be informed is only required if our concern is with the second type of enquiry. For this reason it is neither the case that doctors and researchers should ensure all the information they provide is understood, nor is it the case that their only obligation is to disclose it.

According to a standard view, the physical boundary of the person—the skin-and-skull boundary—matters morally because this boundary delineates between where the person begins and the world ends. On the basis of this view we make a distinction between invasive interventions that penetrate this boundary and non-invasive interventions that do not. The development of neuroprosthetics, however, raises questions about the significance of this boundary and the relationship between person and body. In particular it has been argued by appeal to the Extended (...) Mind thesis that mind and person can extend beyond the body, and hence the skin-and-skull boundary is of questionable significance. In this paper I argue that the Extended Mind thesis is consistent with the ethical relevance of the skin-and-skull barrier. Although it can be argued that cognitive processes and aspect of mind can extend beyond the skin-and-skull boundary as EM claims, it does not follow that the person is also extended beyond this boundary. The moral sense of person is closely related to the notion of person as a subject of experiences and this, in turn, is related to the sensory and somatosensory aspects of the body. The development of neuroprosthetics provides us with reason to see that persons can be variously embodied, but this is consistent with the functional and ethical significance of the skin-and-skull boundary.

Environmental ethics rests on a mistake. At least a common conception of what such an ethic must be like rests on a mistake. To make this clearer, I first explain this conception, then characterize and defend the charge I make against it.

This paper critically engages the legal and political framework for responding to democracy and rule of law backsliding in the EU. I develop a new and original critique of Article 7 TEU based on it being democratically illegitimate and normatively incoherent qua itself in conflict with EU fundamental values. Other more incremental and scaleable responses are desirable, and the paper moves on to assess the legitimacy of economic sanctions such as tying access to EU funds to performance on democratic and (...) rule of law indicators or imposing fines on backsliding states. I hold such sanctions to be a priori legitimate, and argue that in some cases economic sanctions are even normatively required, given that EU material support of backsliding member states can amount to material complicity in their backsliding. However, an economic conditionality mechanism would need to be designed to minimize unjust and counterproductive effects. One way to pursue this could be to complement sanctions against the backsliding government with investment for prodemocratic actors in that state. (shrink)

The criticism that voluntary codes of conduct are ineffective can be met by giving greater centrality to human rights in such codes. Provided the human rights obligations of multinational corporations are interpreted as moral obligations specifically tailored to the situation of multinational corporations, this could serve to bring powerful moral force to bear on MNCs and could provide a legitimating basis for NGO monitoring and persuasion. Approached in this way the human rights obligations of MNCs can be taken to include (...) support for political as well as economic rights. This will go some way towards filling the regulatory gap created by the difficulty of controlling the activities of corporations operating globally. However, such a proposal will require a measure of ‘meta-regulation’ whereby the operations of MNCs are legally required to be sufficiently transparent to create the conditions for effective external moral scrutiny.

After expressing our gratitude to the commentators for their valuable analyses and assessments of Principles of Biomedical Ethics, we respond to several particular critiques raised by the commentators under the following rubrics: the compatibility of different sets of principles and rules; challenges to the principle of respect for autonomy; connecting principles to cases and resolving their conflicts; the value of and compatibility of virtues and principles; common morality theory; and moral status. We point to areas where we see common agreement (...) with our commentators and respond to their critical evaluations. (shrink)

Algorithmic information theory gives an idealized notion of compressibility that is often presented as an objective measure of simplicity. It is suggested at times that Solomonoff prediction, or algorithmic information theory in a predictive setting, can deliver an argument to justify Occam’s razor. This article explicates the relevant argument and, by converting it into a Bayesian framework, reveals why it has no such justificatory force. The supposed simplicity concept is better perceived as a specific inductive assumption, the assumption of effectiveness. (...) It is this assumption that is the characterizing element of Solomonoff prediction and wherein its philosophical interest lies. (shrink)

Paul Boghossian has argued that Externalism is incompatible with privileged self-knowledge because (i) the Externalist can cite no property to be the reference of an empty natural kind concept such as the ether; (ii) without reference there is no content; hence (iii) either we do know on the basis of introspection alone whether an apparent natural kind thought has content or not, in which case we can infer from self-knowledge and a priori knowledge of Externalism alone to the existence in (...) our environment of water, gold etc.; (iv) or we do not know, without empirical investigation, whether an apparent natural kind thought has content. An Externalist not wanting to accept either (iii) or (iv) can deny (i). All empty natural kind concepts refer to the necessarily uninstantiated property of being identical to nothing. Since they have different senses and self-knowledge is only held to extend to the existence and identity of sense, this is compatible with privileged self-knowledge, and Externalism is still true of the concepts.

I aim to draw the reader's attention to an easily overlooked account of perception, namely that there are no perceptual experiences, that to perceive something is to stand in an external, purely non-Leibnizian relation to it. I introduce the Purely Relational account of perception by discussing a case of it being overlooked in the writings of G.E. Moore, though we also find the same move in J. Cook Wilson, so it has nothing to do with an affection for sense-data. I (...) then discuss the relation between the PR account and recent disjunctive accounts of perceptual experience, and note that the PR account has some claim to be the only one that truly respects the directness of perception. The paper does not aspire to persuade the reader of the correctness of the neglected PR account, merely that it should be treated as a serious candidate in philosophical debates about perception.

Politics, Philosophy & Economics, Volume 21, Issue 4, Page 393-414, November 2022. Sometimes, people consent to sex because they face social constraints. For example, someone may agree to sex because they believe that it would be rude to refuse. I defend a consent-centric analysis of these encounters. This analysis connects constraints from social contexts with constraints imposed by persons e.g. coercion. It results in my endorsing what I call the “Constraint Principle.” According to this principle, someone's consent to a sexual (...) encounter lacks justificatory force if they are consenting because withholding consent has an adverse feature, they are entitled to withhold consent without it being the case that withholding consent has this adverse feature; and it is not the case that the consent-giver has sincerely expressed that, out of the options that are available to their sexual partner, they most prefer to go through with the sexual encounter in the circumstances.

In an article published in 2009 titled "How Do Mādhyamikas Think?" I tried to go some distance with Yasuo Deguchi, Jay Garfield, and Graham Priest (henceforth "DGP") in reading certain Buddhist texts as dialetheist.1 The dialetheism that I saw as plausible for the Prajñāpāramitā-sūtras and Nāgārjuna was not the full-blown robust variety of DGP (i.e., acceptance of the truth of some statement of the form p & ¬p) but a non-adjunctive variety, acceptance of p and acceptance of ¬p. In short, (...) the adjunctive move to p & ¬p is blocked.In the article, I focused on texts like the Vajracchedikā Prajñāpāramitā-sūtra ("Diamond Cutter Suūtra") with its famous "signature formulae" along the lines of "x does not exist / x is not ..

Drawing upon the thought of Giorgio Agamben, this essay focuses upon the potential of a single act to change a political order. Agamben’s writings retain the possibility for a paradigmatic gesture that opens a space for a politics not founded on a form of belonging grounded in a particular property, such as national identity. To illustrate this event this essay turns to Agamben’s construction of whatever-being, which is constructed hyper-hermeneutically. This term is chosen deliberately. Whatever-being retains a hermeneutic structure, but (...) is constructed through singular paradigmatic examples. These examples are evidence for whatever-being’s existence as a pure singularity, unable to be reduced to a particular quality. Such examples are gestures that allow future modes of belonging to separate themselves from oppressive foundations and dominating constructions of political existence, through revealing the possibility of a new way of being that does not require a revolutionary “zero hour” to be brought about.

Affirmative action refers to positive steps taken to hire persons from groups previously and presently discriminated against. Considerable evidence indicates that this discrimination is intractable and cannot be eliminated by the enforcement of laws. Numerical goals and quotas are justified if and only if they are necessary to overcome the discriminatory effects that could not otherwise be eliminated with reasonable efficiency. Many past as well as present policies are justified in this way.

Giorgio Agamben: Legal, Political and Philosophical Perspectives brings together contributions from scholars in a number of fields including many who have worked closely with Agamben in order to argue that Agambens thought is vital to the future directions of research in the humanities and social sciences. The book is divided into three sections, each coalescing around a different perspective. Contributions in the first section examine the potential for Agambens thought to impact upon future legal scholarship. Papers draw upon wide ranging (...) issues such as legal oaths, legal reasoning and Hegels Philosophy of Right. The second section focuses on political perspectives that include references to Marx, Žižek and Agambens concept of the messianic. The third section considers philosophical perspectives on Agambens thought, and draws upon art theory, Franz Kafka, and the thought of Gilles Deleuze, Walter Benjamin and Emmanuel Levinas. All three sections, however, address the potential of Agambens thought by re-focusing attention away from his critiques of Western politics and towards his scheme for a political future. As such the book maintains that Agamben is an important and thoroughly original figure, who has articulated a vision of politics, and of community, that is both achievable and worth recognising.

This book explores how the figure of the slave has been used to construct ideas of freedom in Western political and legal philosophy. The figure of the slave has supported philosophical and legal defences of colonialism, coloniality and the supremacy of the white subject. Yet for Giorgio Agamben, the slave stands (almost counterintuitively) as an exemplar of a potential form of future positive political existence. Developing this line of thought, the book reads key thinkers Agamben engages with in his thought (...) and writings - including Aristotle, Saint Paul and G W F Hegel - and draws on decolonial theory to argue that the lives of people who were enslaved and unfree, and their actions and gestures, can point towards a paradigmatic form of political belonging. By reading Agamben in a decolonial direction, we can imagine alternative forms of agency, recognition and subjectivity, which can challenge the necropolitical world of racial capitalism in which we live. This study will appeal to scholars, researchers and graduate students with an interest in the thought of Giorgio Agamben, radical politics, legal and political philosophy and decolonial theory.

It makes sense to ask from time to time where we are in the philosophical discussion. This article reviews the debate in the twentieth century. Michael Friedman has recently argued that the split between Continental and analytic philosophy is due to the inability, because of war, to carry forward a genuine debate begun by Heidegger and Carnap around the time of Heidegger's public controversy with Cassirer at Davos in 1929. I, however, argue that there was not even the beginning of (...) a genuine debate between Heidegger and Carnap. I argue further that the split between analytic and Continental philosophy originated earlier, in the analytic attack on idealism at the beginning of the century. And finally, I argue that the differences among analytic philosophy, Continental philosophy, and pragmatism, the third main current of twentieth-century philosophy, can be traced to differing reactions to Kant.

Hegel's Phenomenology of Spirit, the philosopher's first and perhaps greatest work, is the most important philosophical treatise of the nineteenth century. In this companion volume to his general introduction to Hegel, Tom Rockmore offers a passage-by-passage guide to the Phenomenology for first-time readers of the book and others who are not Hegel specialists. Rockmore demonstrates that Hegel's concepts of spirit, consciousness, and reason can be treated as elements of a single, coherent theory of knowledge, one that remains strikingly relevant for (...) the contemporary discussion. He shows how the various conceptions of cognition developed in the text culminate in absolute knowing, which Rockmore reads, in opposition to the frequent religious readings of Hegel, in a wholly secular manner. Unlike commentators who isolate Hegel's text from its philosophical origins, Rockmore analyzes the book in the philosophical context from which it emerged, lucidly discussing notoriously difficult passages in relation to the ideas of Aristotle and Descartes, and above all to those of Kant and other German idealists.

In defense of anarchism Robert Paul Wolff contends that the moral autonomy of individuals cannot be made compatible with legitimate political authority. A state is legitimate, he maintains, if authorities in the state have a right to command where subjects correlatively have an obligation to obey. However, he also holds both that all autonomous individuals have a primary obligation to refuse to be ruled by all authorities and that all men are normally obliged to remain autonomous. It allegedly follows that (...) anarchism is the only political theory consistent with autonomy. We propose to show that his arguments concerning legitimacy contain a crucial inconsistency and that his conclusions concerning the incompatibility of authority and autonomy fail. (shrink)

Piéron's Law describes the relationship between stimulus intensity and reaction time. Previously (Stafford & Gurney, 2004), we have shown that Piéron's Law is a necessary consequence of rise-to-threshold decision making and thus will arise from optimal simple decision-making algorithms (e.g., Bogacz, Brown, Moehlis, Holmes, & Cohen, 2006). Here, we manipulate the color saturation of a Stroop stimulus. Our results show that Piéron's Law holds for color intensity and color-naming reaction time, extending the domain of this law, in line with our (...) suggestion of the generality of the processes that can give rise to Piéron's Law. In addition, we find that Stroop condition does not interact with the effect of color saturation; Stroop interference and facilitation remain constant at all levels of color saturation. An analysis demonstrates that this result cannot be accounted for by single-stage decision-making algorithms which combine all the evidence pertaining to a decision into a common metric. This shows that human decision making is not information-optimal and suggests that the generalization of current models of simple perceptual decision making to more complex decisions is not straightforward.

RIVALRY AND CENTRAL PLANNING: THE SOCIALIST CALCULATION DEBATE RECONSIDERED by Don Lavoie. New York: Cambridge University Press, 1985. 208 pp., $34.95.

A fundamental misapprehension of the nature of our being in the world underlies the general inhumanity and incoherence of modern culture. The belief that abstraction as a mode of knowing can be universalized to provide a rational ground for all human knowledge and action is a pernicious and unacknowledged background to several modern diseases. Illustrative of these maladies is the seeming dichotomy between the aesthetic and the analytic approaches to nature. One critical arena in which the incoherences of our current (...) understandings of our place in nature come to light is in the battle over the environment. I argue that a more adequate conceptualization of our place in the natural world can be erected if the central metaphors for our understanding are grounded in notions derived from the sciences of life. The key concepts must include contingency, historicity, evolution, organism, and imaginative interaction with concrete reality in individual human beings. (shrink)

This article attempts to lean against the suffocating trend towards mourning, theological exegesis and close-circuit canonisation that has characterised Derrida studies in the wake of his death. On Touching is particularly brutal towards Nancy's presumption of a ‘post-deconstructive’ haptics in a manner that extends to a general discipleship (glossing Derrida's remark, ‘I am not of the family’). Summarising the entire course of Derridean ‘deconstruction’ (departing from phenomenology, recycling early studies), On Touching may be his most political monograph. Yet in cutting (...) off Nancy, Derrida at once cuts off ‘future’ extensions while turning aside from any projection of what lies beyond this then closed history except for complex references to memory machines. This essay then asks what teletechnic media already knows of the prosthetic hand and eye by turning to Hitchcock's Spellbound, where a propping-up of the senses by technics is allowed to exceed, or virtually suicide, itself. In refusing to address any ‘beyond’ of a metaphysical haptics while cutting off his own future extenders (readers, progeny), Derrida raises (yet turns from) the question of what exceeds this closed history entering 21st-century horizons.
