This book argues that, despite recent calls to arms to seek out and remove "corporate psychopaths" from the business world, efforts to eliminate the corporate psychopath presence would be illegal as well as unethical.

It is shown how martingale convergence theorems apply to coherent belief change in radical probabilist epistemology.

As late as 1948, when he was making his report to the Literae Humaniores Faculty Board on the work he had done as University Lecturer since 1945, Friedrich Waismann listed three text books that he had ready for publication and one book—as it might be “real book”—which he referred to as “Philosophy and Grammar”. That was his fi nal title for a work he had been preparing since 1929 and which was originally to be called “Logik Sprache Philosophie”. In 1948 (...) that work will have consisted physically in a heavily corrected set of galley proofs, printed for Routledge and Kegan Paul . The print was set up in the unhappy year of 1939, the copy reaching the publisher on 25 July of that year. (shrink)

Renin is the rate‐limiting enzyme in a cascade that leads to production of angiotensin II, which is perhaps our most important regulator of salt and water balance and blood pressure. In this personal perspective, I describe how I entered the renin field 33 years ago by discovering that proteases increased the level of renin activity in biological fluids, so revealing the existence of a ‘pro’ form of the molecule. This led me on a journey that encapsulated all of the major (...) milestones in molecular discovery for renin. These included (1) the elucidation of the steps in renin biosynthesis, (2) the cloning of renin cDNA and its gene, (3) demonstration of the structure of the renin protein, (4) using the renin gene in the first genetic studies in hypertension, (5) finding the mechanism by which the major controller, cyclic AMP, regulates the promoter, (6) showing that a strong enhancer and its weak promoter control this physiologically regulatable gene in accord with the variegation (on/off switching) model, and (7) being the first to identify molecules involved in posttranscriptional control. The renin molecule, its gene and molecular control are now very well understood, but more fine details on the topic of renin continue to emerge to delight ‘reninologists’ and others.

Reinforcement schemes are a class of non-Markovian stochastic processes. Their non-Markovian nature allows them to model some kind of memory of the past. One subclass of such models are those in which the past is exponentially discounted or forgotten. Often, models in this subclass have the property of becoming trapped with probability 1 in some degenerate state. While previous work has concentrated on such limit results, we concentrate here on a contrary effect, namely that the time to become trapped may (...) increase exponentially in 1/x as the discount rate, 1− x, approaches 1. As a result, the time to become trapped may easily exceed the lifetime of the simulation or of the physical data being modeled. In such a case, the quasi-stationary behavior is more germane. We apply our results to a model of social network formation based on ternary (three-person) interactions with uniform positive reinforcement. (shrink)

Practical reasoners are resource-bounded—in particular they require time to derive consequences of their knowledge. Building on the Timed Reasoning Logics (TRL) framework introduced in [1], we show how to represent the time required by an agent to reach a given conclusion. TRL allows us to model the kinds of rule application and conflict resolution strategies commonly found in rule-based agents, and we show how the choice of strategy can influence the information an agent can take into account when making decisions (...) at a particular point in time. We prove general completeness and decidability results for TRL, and analyse the impact of communication in an example system consisting of two agents which use different conflict resolution strategies.

This study develops a Heideggerian thesis on the significance of Dasein's bodiliness. In Grundbegriffe der aristotelischen Philosophie , Heidegger claims that bodiliness secures the ground for the full being of the human. I situate this thesis squarely within die Sache selbst for Heidegger. Die Sache selbst concerns the issue of how being itself is engendered in human understanding . From as early as 1921, Heidegger explicitly understands his central topic in terms of ki&d12;nh siv . That is, the emergence of (...) being in conjunction with the ontological structure of the human being is ultimately intelligible as a kind of movement. The 1924 thesis makes sense ultimately insofar as bodiliness itself is understood as the ontological movement---the original being-moved or pa&d12;qov ---that allows entities to appear within the domain of human concerns. After examining Heidegger's retrieval of several key Aristotelian concepts , I interpret bodiliness as the always already operative being-pulled-out-ahead-of-itself by its own essential lack. Entities are first able to be present to Dasein because Dasein is opened in this way. Thus, bodiliness on my reading is die Sache selbst. My interpretation of Heidegger's thesis also forms the interpretive starting point for a rereading of Geworfenheit and Gewesenheit as concepts of bodiliness. As Dasein's original pa&d12;qov , bodiliness in Sein und Zeit would go by the name die gewesene Geworfenheit: the a priori or always already operative thrown-open-ness that first allows being to emerge to human understanding.

This article explores the integrity of the discourse in the Anglican eucharistic tradition by considering the philosophical assumptions that underlie eucharistic theology. It argues that where the conversation of the Anglican eucharistic tradition is open and unfinished then the integrity of the discourse is facilitated as opposed to the conversations of party positions and particular interests which suggest exclusive versions of truth. The conversation or dialogue of Anglican eucharistic theology is seen to be enhanced through the consideration of the philosophical (...) assumptions of realism and nominalism to both the moderate and immoderate degrees that underpin eucharistic theology as a state of affairs. The insights of contemporary philosophers are used as a way of conceptualising the discourse of the Anglican eucharistic tradition and a model of Anglican eucharistic theology is suggested as a means of facilitating the integrity of the discourse through the recognition of multiformity in the tradition and by distancing the discourse from the hermeneutic idealism of particular interest.

There has been a recent surge of interest among economists in developing models of doxastic states that can account for some aspects of human cognitive limitations that are ignored by standard formal models, such as awareness. Epistemologists purport to have a principled reason for ignoring the question of awareness: under the equilibrium conception of doxastic states they favour, a doxastic state comprises the doxastic commitments an agent would recognise were he fully aware, so the question of awareness plays no role. (...) The objective of this paper is to scrutinize this argument. A thesis underlying the argument, which we call the independence of doxastic commitments with respect to awareness, is identified, and examples are given where it appears to be violated. By considering these examples, one can get an idea of the price of accepting this thesis. On the one hand, one can escape the conclusion that the thesis is violated, but only at the expense of another principle espoused by all major formal models of belief, which we call constant doxastic rest; and abandoning this principle necessitates extensive revision of current models of belief. On the other hand, there are epistemologically valid reasons for thinking that the thesis fails to hold in the examples, which have to be rebutted if the thesis, and the equilibrium justification for ignoring the issue of awareness, are to be retained.

This article explores and unpacks the public debate on the ethics of applying selection quotas to South African international sport sides to achieve transformation, with special attention to cricket and rugby, the Proteas and Springboks respectively. I claim that for quotas to be morally called for, the racial transformation they are in service of must be morally required. Following an earlier article of mine on the subject of transformation in South African sport, I briefly reject two manifestations of the goal (...) of having the sides’ racial demographics match those of the country as a whole, and proceed to defend and develop two different transformational requirements: the ending of ongoing racial bias and the provision of equality of opportunity. I argue that while there may be a place for alternative forms of affirmative selection, the case for rigid quotas is marginal at best. While I do not argue for the claim here, it neither follows from this, nor do I believe, that the use of quotas is morally wrong. I argue only that the case for them is not particularly strong and depends, particularly, on the extent to which ongoing racial bias in selection persists. (shrink)

Externalist theories of thought content are sometimes arrived at by reflection upon Twin Earth thought experiments of the sort made famous by Hilary Putnam and Tyler Burge. The conclusion many philosophers draw from these thought experiments is that certain types of thought contents are individuated, in part, by environmental or socioenvironmental factors. This doctrine of "Twin Earth content-externalism" implies that it is possible for thinkers that are alike in all intrinsic physical respects to differ in the contents of their thoughts (...) by virtue of differences in their environments.

This essay is a reading of two Hollywood films: The Defiant Ones (1958, directed by Stanley Kramer, starring Tony Curtis and Sidney Poitier) and Rising Sun (1993, directed by Philip Kauffman starring Wesley Snipes and Sean Connery, based on the Michael Crichton novel of the same name). The essay argues that these films work to contain black demand for social and political equality not through exclusionary measures, but rather through deliberate acknowledgment of blackness as integral to US identity. My reading (...) shows how a homosocial bond between white and black stands in for US national identity, and how this identity is unified by foregrounding the threat of an apocalyptic outcome. I use the concept of brinkmanship to illustrate the political effects of this particular narrative form. Then I move to Rising Sun, a film that employs a racial triangle of white, black and Asian men to manage black demand for social change. I argue that the narrative logic and the cultural politics of the film require any figure that is both Asian and masculine to be coded as a foreign enemy. (shrink)
