The strange story of the von Neumann impossibility proof is recalled, and the even stranger story of later impossibility proofs, and how the impossible was done by de Broglie and Bohm. Morals are drawn.

This paper is a response to Nicholas Dixon's defence of the moderate partisan as the ideal fan of team sports. For Dixon, the moderate partisan is someone who combines a partisan fan's loyalty for a particular team with a purist fan's desire to see fair and skilful play by all participants. My aim is to argue that there is no ideal fan of team sports. In particular, there is nothing specially commendable about the moderate partisan's loyalty that justifies the claim (...) to be the ideal fan. There are many other ways of being a fan than being a purist or a partisan as described by Dixon. None of them is morally superior to the other, assuming that they meet basic requirements of respect for others and for fair play. I argue that the commitment of partisan fans to particular teams is better explained by other values than the moral virtue of loyalty. A better explanation and justification of partisanship, and indeed of fan interest in sport generally, is found in the human attachment to narrative as a way of creating meaning in our lives.

To be free is to escape all limitations and obstacles—or so we think at first. But if we probe further, we discover that freedom embraces its own necessities, a set of conditions without which it could not exist. _Freedom's Embrace_ explores these necessities of freedom. J. Melvin Woody surveys competing conceptions of freedom and traces debates about the nature and reality of freedom to confusions about knowledge, humanity, and nature that are rooted in some of the most fundamental assumptions of (...) modern Western thought. The preemption of freedom as an exclusively human privilege with all nature relegated to mechanical necessity is a fatal error that renders both humanity and nature equally unintelligible. What distinguishes human beings from other animals is not freedom but the use of symbols, which vastly extends the range of available options and enables us to envision freedom as an ideal by which customary institutions and norms may be judged and transformed. By carefully surveying its necessary conditions and limitations, Woody reconciles the salient competing conceptions of freedom and weaves them together into a richer and broader theory that resolves old controversies and opens the way toward an ethics of freedom that can meet the challenges of relativism and nihilism that arise from recognizing the historicity and malleability of culture.

This paper challenges defenders/advocates of the semantic-completeness route towards gluts to explain, in simple and plausible terms, why the ‘trivializer paradox’, framed in terms of closure relatives on theories, fails to undermine their argument.

We consider the following question of Kunen: Does Con(ZFC + ∃M a transitive inner model and a non-trivial elementary embedding j: M $\longrightarrow$ V) imply Con (ZFC + ∃ a measurable cardinal)? We use core model theory to investigate consequences of the existence of such a j: M → V. We prove, amongst other things, the existence of such an embedding implies that the core model K is a model of "there exists a proper class of almost Ramsey cardinals". Conversely, (...) if On is Ramsey, then such a j, M are definable. We construe this as a negative answer to the question above. We consider further the consequences of strengthening the closure assumption on j to having various classes of fixed points. (shrink)

In this paper, we describe Blackboard’s Online Journal program and explain how we use the online journal in a variety of philosophy courses. We outline our pedagogical motivation for using online journals and analyze how online journals help to improve our students’ ability to read, write and think philosophically. We analyze the strengths and weaknesses of online journals in comparison to online discussion boards. Finally, we address several concerns that philosophy teachers may have about using online journals.

Amit's Hebbian model risks being overexplanatory, since it does not depend on specific physiological modelling of cortical ANNs, but concentrates on those phenomena which are modelled by a large class of ANNs. While offering a strong demonstration of the presence of Hebb's “cell assemblies,” it does not offer an equal account of Hebb's “phase sequence” concept.

Anselm's argument has two distinct conclusions: (a) we cannot intelligibly doubt that god exists, and (b) this god, whose existence we cannot doubt, exists necessarily. if we replace anselm's vague conception of god by the spinozistic conception of substance, a defensible version of the ontological argument, understood as having these two conclusions, can be constructed. two important consequences of this analysis are: (1) the ontological argument, properly understood, deals simply with the concept of substance. it is a further question whether (...) substance ought to be understood as god. (2) the ontological argument does not actually demonstrate the existence of anything. it simply makes clear the consequences of adopting a metaphysical view which employs the spinozistic conception of substance.
