Whittaker, following Siebeck, pointed out the important role Plotinus assigns to the functions of imagination in psychic life. Imagination is the terminus ad quern of all properly human conscious experience; it is that faculty of man without which there can be no conscious experience. The sensitive soul is an imaginative soul below which there is Nature, or vegetative soul, which acts without being conscious. When the functions of reason are added to sensation to produce a rational human being, there is (...) conscious discursive thought as well as conscious sensation; and since the sensitive soul cannot be responsible for the imaging of rational concepts, Plotinus asserts the existence of a conceptual imagination.

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and life, and life and mind, are discarded, and the old conflict between science and religion shown to belong to an out-of-date world view.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)

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)

In a preceding paper [1] it was shown that quantum logic, given by the tableaux-calculus Teff, is complete and consistent with respect to the dialogic foundation of logics. Since in formal dialogs the special property of the 'value-definiteness' of propositions is not postulated, the calculus $T_{eff}$ represents a calculus of effective (intuitionistic) quantum logic. Beginning with the tableaux-calculus the equivalence of $T_{eff}$ to calculi which use more familiar figures such as sequents and implications can be investigated. In this paper we (...) present a sequents-calculus of Gentzen-type and a propositional calculus of Brouwer-type which are shown to be equivalent to $T_{eff}$ . The effective propositional calculus provides an interpretation for a lattice structure, called quasi-implicative lattice. If, in addition, the value-definiteness of quantum mechanical propositions is postulated, a propositional calculus is obtained which provides an interpretation for a quasi-modular orthocomplemented lattice which, as is well-known, has as a model the lattice of subspaces of a Hilbert space.

This contribution gives an outline of a game theoretic foundation of the logical structure inherent to the language of a science. Game theoretic approaches to a language were considered and developed by several authors. In this volume Saarinen examines the game theoretic semantics due to Hintikka and the dialog-game semantics due to Lorenzen. In the following I shall not re-examine the approaches by Hintikka and Lorenzen. However, some remarks about Lorenzen’s semantics are necessary since the game theoretic approach considered here (...) is essentially based on the idea of Lorenzen to use dialog-games for a foundation of logic.A systematic game theoretic presentation of the rules of a dialog game was given at first by Lorenz. Starting with certain structural rules which constitute the general scheme of a dialog, a further dialog rule is necessary in order to guarantee a finite game. (shrink)

This paper offers an intellectual discourse for destination managers by exploring alternative branding approaches used during the colonial period in Kenya, now that the image is under siege both internally through socio-economic instability and unprecedented levels of poaching, and externally through travel warnings, outright trafficking in big game trophies, the constant threat of terror attacks, and poor global rankings in the Travel and Tourism Competitive Index. The paper conforms to the mission of thought and practice by identifying practical ways of (...) promoting tourist destination Kenya through an in-depth analysis of historical experiences. (shrink)

Is the assimilation of these two formulations of the moral principle by Kant and some of his expositors justified? In the Analytic of Pure Practical Reason Kant claims that his view of morality agrees with the ancient command that man should love his neighbour as himself. Also in the Fundamental Principles of the Metaphysic of Morals he regards the Golden Rule as a deduction, though with several limitations, from the second version of the Categorical Imperative.
