This is the first part of a two-volume study which may very well represent a turning point of scholarship on Heidegger and a step beyond his position. Paradoxically this work is outstanding both as criticism and as close interpretation of Heidegger. The critical perspectives on Heidegger developed by Regina carry to their natural conclusion some important analyses of the theme of finitude contributed by his colleague, E. Severino, in the mid-sixties. These analyses made clearer the relationship between finitude and the (...) nihilistic tendencies discovered by Heidegger in Western thought. What Heidegger calls metaphysics is the history of the efforts to negate finitude and contingency by ascribing necessity and original worth to one or another ontic property of beings. Heidegger promised on various occasions a destructive history of metaphysics, but his thought in this respect has developed in fragments--on Nietzsche, Descartes, Leibniz, Kant, Plato, Aristotle, and the Presocratics--which require a considerable work of piecing together. Regina's own thesis on finitude, which parallels the important contributions of Michel Henry, makes these pieces fit in what is possibly the best ensemble yet devised with them. A truly brilliant feature of this interpretation is its emphasis on the role attributed to Kant by Heidegger, a role which places Kant outside Western metaphysics and among the pioneers of theoretical investigation of the ties between finitude and transcendence. The direction in which this first part of Regina's work points is that of a possible refocusing on those aspects of Heidegger's work that revalue human dignity. Such refocusing can have so productive an impact on the unification of philosophical work in Europe that the second part of this study should be anxiously awaited.--A. M. (shrink)

Synaesthesia is a condition in which one type of stimulation evokes the sensation of another, as when the hearing of a sound produces photisms, i.e. mental percepts of colours. R is a 20 year old colour blind subject who, in addition to the relatively common grapheme-colour synaesthesia, presents a rarely reported cross modal perception in which a variety of visual stimuli elicit aura-like percepts of colour. In R, photisms seem to be closely related to the affective valence of stimuli and (...) typically bring out a consistent pattern of emotional responses. The present case study suggests that colours might be an intrinsic category of the human brain. We developed an empirical methodology that allowed us to study the subject's otherwise inaccessible phenomenological experience. First, we found that R shows a Stroop effect elicited by photisms despite the fact that he does not show a regular Stroop with real colours. Secondly, by manipulating the colour context we confirmed that colours can alter R's emotional evaluation of the stimuli. Furthermore, we demonstrated that R's auras may actually lead to a partially inverted emotional spectrum where certain stimuli bring out emotional reactions opposite to the normal ones. These findings can only be accounted for by considering R's subjective colour experience or qualia. Therefore the present paper defends the view that qualia are a useful scientific concept that can be approached and studied by experimental methods. (shrink)

The Birkhoff-Maltsev problem asks for a characterization of those lattices each of which is isomorphic to the lattice L(K) of all subquasivarieties for some quasivariety K of algebraic systems. The current status of this problem, which is still open, is discussed. Various unsolved questions that are related to the Birkhoff-Maltsev problem are also considered, including ones that stem from the theory of propositional logics.

We assume, in the first place, that two kinds of processes occur in nature: the strictly continuous and causal ones, which are governed by the Schrödinger equation and those implying discontinuities, which are ruled by probability laws. In the second place, we adopt a postulate ensuring the statistical sense of conservation laws. These hypotheses allow us to state a rule telling, in principle, in which situations and to which vectors the system's state can collapse, and which are the corresponding probabilities. (...) The way our proposed approach works is illustrated with some examples and with the analysis of the measurement problem. We obtain the exponential decay law. A comparison with other attempts to solve the measurement problem is performed. (shrink)

LetL(K) denote the lattice (ordered by inclusion) of quasivarieties contained in a quasivarietyK and letD 2 denote the variety of distributive (0, 1)-lattices with 2 additional nullary operations. In the present paperL(D 2) is described. As a consequence, ifM+N stands for the lattice join of the quasivarietiesM andN, then minimal quasivarietiesV 0,V 1, andV 2 are given each of which is generated by a 2-element algebra and such that the latticeL(V 0+V1), though infinite, still admits an easy and nice description (...) (see Figure 2) while the latticeL(V 0+V1+V2), because of its intricate inner structure, does not. In particular, it is shown thatL(V 0+V1+V2) contains as a sublattice the ideal lattice of a free lattice with free generators. Each of the quasivarietiesV 0,V 1, andV 2 is generated by a 2-element algebra inD 2. (shrink)

How ought Christians to approach moral problems? This is a question of method in moral theology. It is also a question of who is in authority to speak on matters of morality. In this essay, the moral methodology of Richard McCormick, S.J., one of the most powerful voices in contemporary Roman Catholic theology, is explored in depth. Attention is focused on its critical details, its development over time, and in particular McCormick's use of authorities in Roman Catholicism. It is argued (...) that his ethical theory is built around one central insight: that the human person in all its facets and dimensions is the criterion of the rightness and wrongness of human actions.

Discusses some of the philosophical ideas about knowledge and applies them to organizational design and information processing in order to create new ideas and new ways of thinking. Explains how this can be achieved by a discussion of the issues surrounding organizational design and the impact of design on information processing. Reviews the ideas concerning the theory of knowledge proposed by rationalists, such as Descartes and empiricists, such as Locke and how these relate to other epistemological theories such as historicism (...) and pragmatism. Concludes by discussing the means by which philosophical theories of knowledge can assist towards new considerations of information processing. (shrink)

Documents as we encounter them in everyday life are complex and diverse things, whether on paper, computer disk or on the World Wide Web. They play many roles vis-à-vis human beings, and the humans engaged with them have diverse responsibilities that are not always easy to fulfil. Added to this is the issue of how a document or literary work can change and yet retain its identity, as found in maintenance, drafting and versioning of documents. This paper explores how the (...) meaning-oriented philosophy of Herman Dooyeweerd may be used to understand the complex nature of documents, to throw light on the roles, responsibilities and culture surrounding them, and to tackle issues of identity and change.

The same research proposal was submitted to 24 district health authority (DHA) research ethics committees in different parts of the country. The objective was to obtain permission for a multi-centre research project. The study of neonatal care in different types of unit (regional, subregional and district), required that four health authorities were approached in each of six widely separated health regions in England. Data were collected and compared concerning aspects of processing, including application forms, information required, timing and decision-making. The (...) key finding was that ethics committees received and processed the applications variably, reflecting individual factors and local problems. To improve consensus and facilitate multicentre studies, standard forms and instructions are suggested and the establishment of a national committee or advisory group advocated. (shrink)
