This paper is based on a semantic foundation of quantum logic which makes use of dialog-games. In the first part of the paper the dialogic method is introduced and under the conditions of quantum mechanical measurements the rules of a dialog-game about quantum mechanical propositions are established. In the second part of the paper the quantum mechanical dialog-game is replaced by a calculus of quantum logic. As the main part of the paper we show that the calculus of quantum logic (...) is complete and consistent with respect to the dialogic semantics. Since the dialoggame does not involve the 'excluded middle' the calculus represents a calculus of effective (intuitionistic) quantum logic. In a forthcoming paper it is shown that this calculus is equivalent to a calculus of sequents and more interestingly to a calculus of propositions. With the addition of the 'excluded middle' the latter calculus is a model for the lattice of subspaces of a Hilbert space. (shrink)

This paper will begin with a brief account of the mandate and description of the Law Reform Commission of Canada and its Protection of Life Project, secondly, point to a limitation imposed upon it by the nature of health law in Canada and, thirdly propose some basic questions which such commissions have both the luxury and the duty to wrestle with and resolve. In my view it is these fundamental challenges which ought to be the major components of the standards (...) by which national commissions such as ours are judged. (shrink)

Originally published in 1985, this distinguished and constructive critique of modern culture introduced into our language a brand-new term, ‘PN’, standing for ‘psychic nutrition’, which at the time promised to become a household expression. Drawing on his first-hand knowledge of oriental civilizations; on discoveries of Jung, especially his concept of psychic energy; on the ideas of the cultural anthropologists; and not least on the New Science implicit in microphysics and microbiology, E.W.F. Tomlin, whose philosophical books have been translated into several (...) languages, shows how the human psyche requires its own kind of nourishment just as urgently as the body needs food. In the industrial societies of the West, this need has often been ignored. Reformers, in their earnest though sometimes inept endeavours to create a better world, have too often exposed us to the dangers of psychic starvation and the noxious effects of what may be called ‘neg-PN’. Here lie the roots of violence and the lack of direction so conspicuously afflicting modern man and woman. Examples of PN, positive and negative, are given, lending the book an immediacy and practical character often lacking in studies of this kind. In the new scientific approach here adopted, the divisions between matter and life, and life and mind, are discarded, and the old conflict between science and religion shown to belong to an out-of-date world view. The result is a radical reappraisal of the nature and function of religion and art, the two great psychic forces in history. Indeed, the present crisis is shown to originate in the psychic sphere rather than in the political and economic order. Deeply felt and elegantly written, yet not lacking in wit and humour, the book ends with some concrete ideas on how a more balanced culture may be achieved. (shrink)
