Jeffrey Barrett presents the most comprehensive study yet of a problem that has puzzled physicists and philosophers since the 1930s.

In this article, I propose a business paradigm that allows and enables the integration of environmental ethics into business decisions while creating a competitive advantage through the use of an ethical framework based on classical American pragmatism. Environmental ethics could be useful as an alternative paradigm for business ethics by offering new perspectives and methodologies to grant consideration of the natural environment. An approach based on classical American pragmatism provides a superior framework for businesses by focusing on experimentation and innovation, (...) driving a long-term focus, and providing actionable clarity. Under a pragmatic approach to ethics, the choice for sustainability becomes self-evident for business performance and moral reasons. (shrink)

Husserl is well known for his critique of the “mathematizing tendencies” of modern science, and is particularly emphatic that mathematics and phenomenology are distinct and in some sense incompatible. But Husserl himself uses mathematical methods in phenomenology. In the first half of the paper I give a detailed analysis of this tension, showing how those Husserlian doctrines which seem to speak against application of mathematics to phenomenology do not in fact do so. In the second half of the paper I (...) focus on a particular example of Husserl’s “mathematized phenomenology”: his use of concepts from what is today called dynamical systems theory. (shrink)

I develop a “two-systems” interpretation of Husserl’s theory of belief. On this interpretation, Husserl accounts for our sense of the world in terms of (1) a system of embodied horizon meanings and passive synthesis, which is involved in any experience of an object, and (2) a system of active synthesis and sedimentation, which comes on line when we attend to an object’s properties. I use this account to defend Husserl against several forms of Heideggerean critique. One line of critique, recently (...) elaborated by Taylor Carman, says that Husserl wrongly loads everyday perception with explicit beliefs about things. A second, earlier line of critique, due to Hubert Dreyfus, charges Husserl with thinking of belief on a problematic Artificial Intelligence (AI) model which involves explicit rules applied to discrete symbol structures. I argue that these criticisms are based on a conflation of Husserl’s two systems of belief. The conception of Husserlian phenomenology which emerges is compatible with Heideggerean phenomenology and associated approaches to cognitive science (in particular, dynamical systems theory).

Should the authority to make treatment decisions be extended to the competent patient's family? Neither arguments from fairness nor communitarian concerns justify such an infringement on patient autonomy.

I show that the quantum state ω can be interpreted as defining a probability measure on a subalgebra of the algebra of projection operators that is not fixed (as in classical statistical mechanics) but changes with ω and appropriate boundary conditions, hence with the dynamics of the theory. This subalgebra, while not embeddable into a Boolean algebra, will always admit two-valued homomorphisms, which correspond to the different possible ways in which a set of “determinate” quantities (selected by ω and the (...) boundary conditions) can have values. The probabilities defined by ω (via the Born rule) are probabilities over these two-valued homomorphisms or value assignments. So any universe of interacting systems, including those functioning as measuring instruments, can be modelled quantum mechanically without the projection postulate. (shrink)

How do cells direct the microtubule motor protein dynein to move cellular components to the right place at the right time? Recent studies in budding yeast shed light on a new mechanism for directing dynein, involving the protein She1. She1 restricts where and when dynein moves the nucleus and mitotic spindle. Experiments with purified proteins show that She1 binds to microtubules and inhibits dynein by stalling the motor on its track. Here I describe what we have learned so far about (...) She1, based on a combination of genetic, cell biology, and biophysical approaches. These findings set the stage for further interrogation of the She1 mechanism, and raise the question of whether similar mechanisms exist in other species. (shrink)

This chapter examines the theory of moral obligation presented by Robert Adams in Finite and Infinite Goods. The theory holds, quite plausibly, that obligations are requirements which arise within the context of social relationships. It also holds, more controversially, that genuinely moral obligations are requirements resulting from the commands of a loving God. The advantage Adams sees in introducing the notion of a loving God into the theory is that doing so rules out the possibility that certain sorts of horrendous (...) evils, including wanton cruelties, could turn out, according to the theory, to be morally obligatory. This advantage obtains, however, only if God's love is taken to be unlike that of the jealous, strongly preferential sort apparently attributed to God in many biblical passages. Adams does not adequately explain why he identifies the God posited by his theory with the God of the Old and New Testaments. Nor does he adequately explain why one should suppose that a God who conforms to Adams's conception of a perfectly loving being actually exists, given the horrendous evils there are and given the confusing biblical portrait of God as both a horror-defeater and a horror-commander. All things considered, more modest versions of the social theory of obligation appear more plausible than Adams's metaphysically extravagant version. A slightly more modest version would appeal directly to Adams's own theistic theory of excellence, without making reference to divine commands. An even more modest version would eschew the theistic commitments of Adams's ethical theory altogether. The chapter concludes by raising questions about Adams's conception of the metaphysics of morals as a discipline analogous to scientific inquiry into the natural kinds. (shrink)

Current guidelines treat palliative sedation to unconsciousness as an effective medical treatment for terminally ill patients who need relief from severe symptoms, yet also restrict its use in ways that are extraordinary for medical treatments. A closer look at the kinds of cases in which palliative sedation is used suggests a way of adjusting the guidelines to resolve this seeming contradiction.

We present here a hierarchical model for the evolution of compositional language. The model has the structure of a two-sender/one-receiver Lewis signaling game augmented with executive agents who m...

I formulate the interpretation problem of quantum mechanics as the problem of identifying all possible maximal sublattices of quantum propositions that can be taken as simultaneously determinate, subject to certain constraints that allow the representation of quantum probabilities as measures over truth possibilities in the standard sense, and the representation of measurements in terms of the linear dynamics of the theory. The solution to this problem yields a modal interpretation that I show to be a generalized version of Bohm's hidden (...) variable theory. I argue that unless we alter the dynamics of quantum mechanics, or accept a for all practical purposes solution, this generalized Bohmian mechanics is the unique solution to the problem of interpretation.

This paper concerns two composite Lewis-Skyrms signaling games. Each consists in a base game that evolves a language descriptive of nature and a metagame that coevolves a language descriptive of the base game and its evolving language. The first composite game shows how a pragmatic notion of truth might coevolve with a simple descriptive language. The second shows how a pragmatic notion of probability might similarly coevolve. Each of these pragmatic notions is characterized by the particular game and role that (...) it comes to play in the game. (shrink)

Sungmoon Kim’s Confucian Democracy in East Asia: Theory and Practice is a brilliant and engaging contribution to our understanding of democratic theory and practice.1 The title of my comment here emphasizes the innovative way in which Kim moves from practice to theory by relying on the vibrant Confucian civil society in South Korea as both the normative inspiration for and practical reflection of his model of Confucian democracy. In the first section below, I highlight three interrelated ways in which Kim’s (...) book is methodologically quite interesting and then pose some questions about the relation between theory and practice as framed by the book. In the second section, I turn to what I take to be one of the... (shrink)

It is commonly held that Christian ethics generally and Christian bioethics particularly is the application of Christian moral systems to novel problems engaged by contemporary culture and created by contemporary technology. On this view, Christianity adds its moral vision to a technology, baptizing it for use. In this essay, I show that modern technology is a metaphysical moral worldview that enacts its own moral vision, shaping a moral imaginary, shaping our moral perception, creating moral subjects, and shaping what we imagine (...) as moral intentions. In fact, modern technics has its own liturgics, which is foreign to Christian Divine Liturgy. Divine Liturgy is world forming, showing us a different world than the one that comes into relief in the ersatz liturgy of modern medical technics. (shrink)

David Hume’s skeptical solution to the problem of induction was grounded in his belief that we learn by means of custom. We consider here how a form of reinforcement learning like custom may allow an agent to learn how to learn in other ways as well. Specifically, an agent may learn by simple reinforcement to adopt new forms of learning that work better than simple reinforcement in the context of specific tasks. We will consider how such a bootstrapping process may (...) lead to a system that includes trial-and-error forms of learning like win-stay/lose-shift, probe and adjust, and simple reinforcement itself together with higher-rationality inferential tools.

Skyrms-Lewis sender-receiver games with invention allow one to model how a simple mathematical language might be invented and become meaningful as its use coevolves with the basic arithmetic competence of primitive mathematical inquirers. Such models provide sufficient conditions for the invention and evolution of a very basic sort of arithmetic language and practice, and, in doing so, provide insight into the nature of a correspondingly basic sort of mathematical knowledge in an evolutionary context. Given traditional philosophical reflections concerning the nature (...) and preconditions of mathematical knowledge, these conditions are strikingly modest. (shrink)

The Monty Hall Problem (MHP), a process of two-stage decision making, was presented in atypical form via a custom software game. Differing from the normal three-box MHP, the game added one additional box on-screen for each game—culminating on game 23 with 25 on-screen boxes to initially choose from. A total of 108 participants played 23 games (trials) in one of four conditions; (1) “Vanish” condition—all non-winning boxes totally removed from the screen; (2) “Empty” condition—all non-winning boxes remain on-screen, but with (...) an “empty” label on them; (3) “Steroids” condition—all non-winning boxes removed from the screen, with initially chosen box becoming 25% larger; (4) “Steroids2” condition—all non-winning boxes removed from the screen, box not currently chosen becomes 25% larger. Results indicate second-stage on-screen presence of boxes influences switching; with their absence having the opposite effect. Size manipulation appears to elicit demand characteristics resulting in indeterminate influence. (shrink)

A universal property of visual word identification is position-invariant letter identification, such that the letter is coded in the same way in CAT and ACT. This should provide a fundamental constraint on theories of word identification, and, indeed, it inspired some of the theories that Frost has criticized. I show how the spatial coding scheme of Colin Davis can, in principle, account for contrasting transposed letter priming effects, and at the same time, position-invariant letter identification.

The results of two observational studies of clinical directorates (CDs) are presented. The paper exposes fresh perspectives about the management of hospitals and CDs, and suggests that the most important axis on which hospital decision-making rests continues to be profession rather than the CD, even though CDs are designed at least in part to mitigate professional tribalism and bridge professional divides. In empiricising social structural and cultural theories it seems clear that changes to the prescribed organisational framework, which CDs represent, (...) have had negligible effects on behaviour. This being the case, the paper questions the benefits alleged to have accrued from establishing CDs and calls for more effective, micro-behavioural change strategies than merely altering the structure.

An examination of the salient literature on hospital clinical directorates (CDs) is presented. A critique of the largely managerialist, instrumental, hortatory and normative extant literature about CDs is offered. In analysing the literature this way the earlier promotional and critical literature is eschewed in favour of an evaluative approach. CDs are then reconceptualised by locating them within two overarching accounts of social structure—formalised, prescribed frameworks, and enacted, patterned interactions—following the kinds of distinctions made by Giddens, Weick, social action and institutional (...) theorists. Social structure as it relates to culture is also considered, following Martin. Such an approach facilitates an understanding of the general weaknesses of health service perspectives and methods of analysis, and exposes the strengths of Giddens–Weick type paradigms. (shrink)

Borovik proposed an axiomatic treatment of Morley rank in groups, later modified by Poizat, who showed that in the context of groups the resulting notion of rank provides a characterization of groups of finite Morley rank [2]. (This result makes use of ideas of Lascar, which it encapsulates in a neat way.) These axioms form the basis of the algebraic treatment of groups of finite Morley rank undertaken in [1].There are, however, ranked structures, i.e., structures on which a Borovik-Poizat rank (...) function is defined, which are not ℵ0-stable [1, p. 376]. In [2, p. 9] Poizat raised the issue of the relationship between this notion of rank and stability theory in the following terms: “… ungroupede Borovik est une structure stable, alors qu'un univers rangé n'a aucune raison de l'être …” (emphasis added). Nonetheless, we will prove the following:Theorem 1.1.A ranked structure is superstable.An example of a non-ℵ0-stable structure with Borovik-Poizat rank 2 is given in [1, p. 376]. Furthermore, it appears that this example can be modified in a straightforward way to give ℵ0-stable structures of Borovik-Poizat rank 2 in which the Morley rank is any countable ordinal (which would refute a claim of [1, p. 373, proof of C.4]). We have not checked the details. This does not leave much room for strenghthenings of our theorem. On the other hand, the proof of Theorem 1.1 does give a finite bound for the heights of certain trees of definable sets related to unsuperstability, as we will see in Section 5. (shrink)

Certain of Kant’s political essays suggest that the project of socio-political emancipation should be seen as a process of working ourselves out of affective attachments to pathological social relations. This aspect of Kant’s thinking is read through Marx’s materialist notion of commodity fetishism, which provides a paradigmatic approach to understanding the ways in which concrete forms of sociality either thwart or facilitate the process of emancipation. It is then suggested that Freud’s notion of the work of mourning can help to (...) clarify the possibility of breaking with the fixated attachments that contribute to our own domination. In this light, the author considers the respective accounts of the relationship between Freudian theory and Kantian cosmopolitanism given by Julia Kristeva and Judith Butler in light of Theodor Adorno’s materialist account of working-through the past. Reading Freud with Adorno offers a more coherent clarification of the concrete conditions of possibility of cosmopolitanism. (shrink)

If truth hurts, this is no doubt because it is often enough forced on us. And the question as to whether the reception of “nice,” “easy” truths is similarly an outcome of coercion negates itself in its very formulation — we do not ask “why are things the way they are?” from a feeling of comfort; the plaintiff cry of “how, then, shall we live?” does not come to us out of a sense of security. Indeed, insofar as truth overtakes (...) us and interrupts the conventions of our lives, it occurs to us quite apart from our ordinary desires and wants. We are thus faced with a paradox: what claim can truth make on a bein g that “doesn’t need it and doesn’t care about it—since it doesn’t at all concern his needs”? When one considers that the awareness of truth is indexed to lived experience, the paradox is only heightened. (shrink)
