C. S. Lewis sets out to disentangle this knotty issue but wisely adds that in the end no intellectual solution can dispense with the necessity for patience and ...

C. S. Lewis takes us on a profound journey through both heaven and hell in this engaging allegorical tale. Using his extraordinary descriptive powers, Lewis introduces us to supernatural beings who will change the way we think about good and evil.

Investigates the resolution of contradictions and ambiguous derogations in a code, by means of the imposition of partial orderings. Although formulated as a study in the logic of norms, it provided the initial ideas for work on the logic of theory (or belief) change, developed by the authors in a series of papers by the authors and Peter Gardenfors beginning in 1985.

We give a short, critical review of the issue of decoherence. We estab- lish the most general framework in which decoherence can be discussed, how it can be quantified and how it can be measured. We focus on environment induced decoher- ence and its degree of usefulness for the interpretation of quantum theory. We finally discuss the emergence of a classical world. An overall emphasis is given in pointing at common fallacies and misconceptions.

This volume of essays examines the problem of mind, looking at how the problem has appeared to neuroscientists from classical antiquity through to contemporary times. Beginning with a look at ventricular neuropsychology in antiquity, this book goes on to look at Spinozan ideas on the links between mind and body, Thomas Willis and the foundation of Neurology, Hooke’s mechanical model of the mind and Joseph Priestley’s approach to the mind-body problem. The volume offers a chapter on the 19th century Ottoman (...) perspective on western thinking. Further chapters trace the work of nineteenth century scholars including George Henry Lewes, Herbert Spencer and Emil du Bois-Reymond. The book covers significant work from the twentieth century, including an examination of Alfred North Whitehead and the history of consciousness, and particular attention is given to the development of quantum consciousness. Chapters on slavery and the self and the development of an understanding of Dualism bring this examination up to date on the latest 21st century work in the field. At the heart of this book is the matter of how we define the problem of consciousness itself: has there been any progress in our understanding of the working of mind and brain? This work at the interface between science and the humanities will appeal to experts from across many fields who wish to develop their understanding of the problem of consciousness, including scholars of Neuroscience, Behavioural Science and the History of Science.

En este trabajo sc presenta un marco general en el que desarrollar una “ontoepistemo-semántica” para las teodas científicas y sus terminos característicos. En primer lugar, se defiende la esencialidad de los aspectos ontologicos y epistemológicos para la semantica y se hacen explícitos los principios generales que constituyen dicho marco. A continuación, se aplican estos principios al análisis ontoepistemosemántico de cada uno de los tres tipos principales de términos científicos: términos relacionales y funcionales con contenido empírico, términos matemáticos puros y términos (...) para los dominios ontológicos básicos. In this paper I offer a general framework for all “ontoepistemosemantics” of scientific theories and scientific terms. First, I argue for the essential dependence of semantics on ontological and epistemological aspects and I make explicit the general principIes that make up this frame. Then, I apply these principles to the ontoepistemosmantical analysis of the three main kinds of scientific terms: relational and functional term with empirical content, purely mathematical terms and terms for basic ontological domains.

La posibilidad de sentar las bases para una psicología platónica de la acción puede ser abordada desde la perspectiva de la conexión entre la doctrina del alma tripartita de República y la psicología del placer del Filebo. A la luz de dicha conexión, la noción del alma como fuente del deseo se constituye en factor determinante de nuestro carácter personal y nuestra forma de actuar, lo que hace posible construir una tipología de hombre basada en la primacía de una parte (...) de su alma y en su preferencia por cierta clase de placer. Palabras clave: Platón; Psicología; Placer; Alma; Deseo; AcciónThe possibility of laying the foundations of a Platonic psychology of action can be tackled from the connection between Republic’s tripartite soul doctrine and Philebus’ psychology of pleasure. In the light of this connection, the notion of soul as the source of desire is a determining factor of our personal character and the way we act. This makes it possible to construct a typology of man based upon the primacy of one part of his soul and his preference for a certain kind of pleasure. Keywords: Plato; Psychology; Pleasure; Soul; Desire; Action. (shrink)

In philosophy of science two questions become central in the discussion of the nature of empirical science: 1) What is a theory, i.e. how is it built up, how does it work? And: 2) How does a theory relate to its corresponding experiential basis? To deal with these two questions modern philosophy of science has devised various ‘models’ on the nature and working of scientific theories. Some aspects of these models are widely held within the community of philosophers of science, (...) but others are still being discussed quite controversially. In this paper, we will consider both kinds of aspects. Particularly, we will analyze how the meaning of scientific concepts is determined; the axiomatic construction of a scientific theory; the idea of model building views as a bridge between theory and experience; the holistic semantic thesis of science; the question about the true of scientific theories; and, finally, the hierarchic structure of theories.En filosofía de la ciencia, dos cuestiones resultan centrales en la discusión acerca de la naturalezade la ciencia empírica: 1) ¿qué es una teoría ?, es decir, ¿cómo estáconstituida y cómo funciona? y 2) ¿cómo se relaciona una teoría con su correspondientebase experiencial? Para tratar estas dos cuestiones, la moderna filosofía de la ciencia ha desarrolladovarios “modelos” sobre la naturaleza y el funcionamiento de lasteorías científicas. Algunos aspectos de estos modelos son ampliamente aceptados por lacomunidad de filósofos de la ciencia, mientras que otros son todavía discutidos de manerabastante controvertida. En este trabajo, consideraremos ambos tipos de aspectos. En particular,analizaremos cómo se determina el significado de los conceptos teóricos, la construcción axiomática de una teoría científica, la idea de las concepciones sobre la construcción de modelos como puente entre la teoría y la experiencia, la tesis semántica holista de la ciencia, la cuestión acerca de la verdad de las teorías científicas y, finalmente, la estructura jerárquica de las teorías.

The 65th year of a scholar who has devoted 40 years to editing and elucidating Robert Grosseteste provides us with a collection of essays. Not surprisingly, they emanate from colleagues and former students of Richard Dales and reflect his interest, among other concerns, in Grosseteste's aspectus et affectus - range of vision and disposition of mind - those twin peaks with which the 13th century thinker helped to get Christian thought through Aristotle without mutual destruction.
