Ernesto Laclau and Chantal Mouffe’s post-Marxist analysis pushed Gramsci’s anti-determinism to its limits, embracing a post-structuralist, discourse-centred politics. Mouffe’s subsequent programme for radical democracy has sought a renewed democratic left project. While radical democracy’s post-structuralism enables important insights into political subjectivity and antagonism in contemporary democracies, it also weakens its own critical and strategic capacity. By recuperating its Gramscian heritage, radical democracy could be more theoretically and politically effective. In contrast to discourses operating in an entirely open and contingent political (...) field, Gramscian theory offers a more realist – but non-determinist – account of the structural, enabling and constraining properties of ideologies. It also allows for a distinctive institutional space for society. Society is the site upon which political identities are articulated, and from which existing power relations are challenged. But a conception of society also points to the institutional limits to politics, notable by their absence in post-structuralism and radical democracy. (shrink)

The recursion-theoretic study of mathematical structures other thanωis now a field of much activity. Analysis and algebra are two such structures which have been studied for their effective contents. Studies in analysis began with the work of Specker on nonconstructive proofs in analysis [16] and in Lacombe's inspiring notes on relevant notions of recursive analysis [8]. Studies in algebra originated in the work of Frolich and Shepherdson on effective extensions of explicit fields [1] and in Rabin's study of computable fields (...) [15]. Equipped with the richness of modern techniques in recursion theory, Metakides and Nerode [11]–[13] began investigating the effective content of vector spaces and fields; these studies have been extended by Kalantari, Remmel, Retzlaff, Shore and others.Kalantari and Retzlaff [5] began a foundational inquiry into effectiveness in topological spaces. They consider a topological spaceXwith a countable basis ⊿ for the topology. The space isfully effective, that is, the basis elements are coded intoωand the operation of intersection of basis elements and the relation of inclusion among them are both computable. Similar to, the lattice of recursively enumerable subsets ofω, the collection of r.e. open subsets ofXforms a latticeℒunder the usual operations of union and intersection. (shrink)

We discuss the concept of spontaneous breaking of gauge symmetry in super-conductors and superfluids and, in particular, the circumstances under which the absolute phase of a superfluid can be physically meaningful and experimentally relevant. We argue that the study of this question pushes us toward the frontiers of what we understand about the quantum measurement process, and underline the need for a new theoretical framework that keeps pace with modern technological capabilities.

According to a commonly held view, the properties of condensed-matter systems are simply consequences of the properties of their atomic-level components, and all of theoretical research in condensed-matter physics consists essentially in deducing the former from the latter. I argue that this apparently plausible picture is totally misleading, and that condensed-matter physics is a discipline which is not only autonomous, but guaranteed in the long run to be fundamental.

I examine the question of how far experiments that look for the effects of superposition of macroscopically distinct states are relevant to the classic measurement paradox of quantum mechanics. Existing experiments on superconducting devices confirm the predictions of the quantum formalism extrapolated to the macroscopic level, and to that extent provide strong circumstantial evidence for its validity at this level, but do not directly test the principle of superposition of macrostates. A more ambitious experiment, not obviously infeasible with current technology, (...) could provide a direct test between quantum mechanics and a whole class of theories embodying the postulate of realism at the macroscopic level.

I consider various experiments related to the so-called “macroscopic quantum coherence” experiment, which are probably at present in the class of “thought” experiment but are likely to become realistic in the next few decades. I explore the way in which outcomes consistent with the predictions of quantum mechanics would be interpreted by an adherent of, respectively, the Copenhagen, statistical, and Bohmian interpretations of the formalism.

I discuss the question: Is it possible to prepare, by purely thermodynamic means, an ensemble described by a quantum state having a definite phase relation between two component states which have never been in direct contact? Resolution of this question requires us to take explicit account of the nature of the correlations between the system and its thermal environment.

Provides general readers with a clear, nuanced introduction to Budo--the "inner way" of the martial arts.

It is argued that among possible nonlocal hidden-variable theories a particular class (called here “crypto-nonlocal” or CN) is relatively plausible on physical grounds. CN theories have the property that (for example) the two photons emitted in an atomic cascade process are indistinguishable in their individual statistical properties from photons emitted singly, and that in the latter case the effects of nonlocality are unobservable. It is demonstrated that all CN theories are constrained by inequalities which are violated by the quantum-mechanical predictions; (...) these inequalities bear no simple relation to Bell's inequalities, and an explicit example is constructed of a CN theory which violates the latter. It is also shown that while existing experiments cannot rule out general CN theories, they do rule out (subject to a few caveats such as the usual ones concerning the well-known “loopholes”) the subclass in which the photon polarizations are linear.

Scientists, philosophers, and other researchers commonly assert their theories. This is surprising, as there are good reasons for skepticism about theories in cutting-edge research. I propose a new account of assertion in research contexts that vindicates these assertions. This account appeals to a distinct propositional attitude called endorsement, which is the rational attitude of committed advocacy researchers have to their theories. The account also appeals to a theory of conversational pragmatics known as the Question Under Discussion model, or QUD. Hence, (...) I call the theory the EQUD model. Motivating this account is a recognition that the speech act of assertion has two roles to play in research contexts. The first is the advocacy role, in which researchers assert a theory in order to advocate for it. The second is the evidential role, which is used to add to the common stock of information available to a field of inquiry. The EQUD model provides an account of warranted assertion for both these roles in research contexts. This success provides support for the theory of endorsement. It also provides support for information updating accounts of assertion. (shrink)

Im 20. Jahrhundert sind Zweifel an normativ hoch aufgeladenen Unterscheidungen aufgekommen, wie zwischen Mensch und Tier oder zwischen Frau und Mann, und dies hat die Dringlichkeit gesteigert, nicht nur uber bestimmte Unterscheidungen zu streiten, sondern sich auf die Arten und Weisen unseres Unterscheidens selbst zu richten. Unsere Praxis des Unterscheidens lasst sich nicht als ganze uberblicken, sondern nur exemplarisch an bestimmten Unterscheidungsvollzugen reflektieren. Dies geschieht in der vorliegenden Studie am Beispiel der Unterscheidung zwischen Wunsch und Wille. Diese Unterscheidung betrifft unser (...) Selbstverstandnis als Handelnde und sie verweist auf die Erfahrung der Diskrepanz zwischen dem, was wir uns vornehmen und gerne tun wurden, und dem, was wir tatsachlich tun. Das Ziel der exemplarischen Unterscheidungsstudie im ersten Teil wie der methodischen Grundlegung im zweiten Teil liegt darin, einen Grundriss spezifischer, inhaltsgesattigter und systematischer Unterscheidungsforschung zu entwerfen. Votiert wird in Auseinandersetzung mit Platon und Hegel fur eine dynamische Weise dialektischen Unterscheidens. (shrink)

In his most recent work, John Rawls argues that political theory must recognize and accomodate the 'fact of pluralism', including the fact of religious diversity. He believes that the liberal commitment to individual rights provides the only feasible model for accomodating religious pluralism. In this paper, I discuss a second form of tolerance, based on group rights rather than individual rights. Drawing on historical examples, I argue that this is also a feasable model for accomodating religious pluralism. While both models (...) ensure tolerance between groups, only the former tolerates individual dissent within groups. To defend the individual rights model, therefore, liberals must appeal not only to the fact of social pluralism, but also to the value of individual autonomy. This may require abandoning Rawl's belief that liberalism can and should be defended on purely 'political', rather than 'comprehensive' grounds. (shrink)
