It has long been disputed whether Kant's transcendental idealism requires two worlds ? one of appearances and one of things in themselves ? or only one. The one-world view must be wrong if it claims that individual spatio-temporal things can be identified with particular things in themselves, and if it fails to take seriously the doctrine of double affection; versions that insist on one world, without making claims about the identity of individual things, cannot say in what way the world (...) as we know it and the world of things in themselves can be ?the same?. The two-world view must be wrong if it denies Kant's empirical realism, or offers a phenomenalist interpretation of it. On moral grounds Kant ?identifies? each human person with a particular thing in itself, but the relationship here cannot be strict identity; instead its closeness may warrant regarding the two distinct entities as part of a composite whole. Perhaps up to the first edition of the Critique, Kant thought that empirical knowledge required a particular kind of close correspondence between appearances and things in themselves, one that would make it appropriate to speak of composite wholes here also. By the time of the second edition, he saw that there could be no good grounds for thinking that. In this respect something a bit like the one-world theory might make more sense for the first edition than for the second; but in both cases there is room to speak of two worlds as well. Talk of the number of worlds is metaphorical, and both metaphors have their dangers. (shrink)

By considering the irreducible representations of the Lorentz group, an analysis of the different spin-2 waves is presented. In particular, the question of the helicity is discussed. It is concluded that, although from the point of view of representation theory there are no compelling reasons to choose between spin-2 waves with helicity σ=±1 or σ=±2, consistency arguments of the ensuing field theories favor waves with helicity σ=±1.

it is easy to think that he did. Clifford certainly had one. In a celebrated essay he argued for the thesis that “it is wrong always, everywhere and for anyone to believe anything upon insufficient evidence“; and his title was “The Ethics of Belief.” Clifford was not alone, for Huxley, also, was of that same opinion. For him, such belief was not just wrong: it was “the lowest depth of immorality.” With that opinion, and with those advocates of it, James (...) was locked in a struggle throughout his life; and it is a reasonable suspicion that the opponent of one ethics of belief is himself an ethicist with a rival ethics of belief of his own. That suspicion, moreover, appears to be confirmed by James's best known essay. He himself came to the view that his The Will to Believe would have been better named The Right to Believe, and it is a commonplace that “right” is a word of the ethical vocabulary. In short, there are obvious signs pointing to a positive answer to our question. (shrink)

This title provides a synoptic overview of the current state of interdisciplinary research, education, administration and management, and problem solving - knowledge that spans the disciplines and interdisciplinary fields and crosses the space between the academic community and society at large.

Forty‐nine subjects judged the relevancy of sentence parts of a word problem (the Allsports problem). Patterns of subjects' judgments suggest three problem‐solving heuristics: a SETS heuristic, a TIME heuristic, and a QUESTION heuristic. Presentation of the question before the problem tends to suppress SETS and TIME heuristics. A computer program (ATTEND) is presented to simulate subjects' behavior on the Allsports problem. The program is context‐sensitive in that it can change a relevance judgment upon the acquisition of further information. Averaged subject (...) judgments and ATTEND judgments agree for 87% of the items. (shrink)

A repackaged edition of the revered author's classic work that examines the four types of human love: affection, friendship, erotic love, and the love of God—part of the C. S. Lewis Signature Classics series. C.S. Lewis—the great British writer, scholar, lay theologian, broadcaster, Christian apologist, and bestselling author of Mere Christianity, The Screwtape Letters, The Great Divorce, The Chronicles of Narnia, and many other beloved classics—contemplates the essence of love and how it works in our daily lives in one of (...) his most famous works of nonfiction. Lewis examines four varieties of human love: affection, the most basic form; friendship, the rarest and perhaps most insightful; Eros, passionate love; charity, the greatest and least selfish. Throughout this compassionate and reasoned study, he encourages readers to open themselves to all forms of love—the key to understanding that brings us closer to God. (shrink)

C. S. Lewis' article addresses a critically important issue on which Howard Ahmanson comments. Professor Oliver O'Donovan addresses the same issue in a sermon in Christ Church Oxford on Trinity Sunday 1997. We publish the three articles together in the year of the fiftieth anniversary of the independence of India and Pakistan and invite correspondence on the issues at stake. Eds.
