J.W. Olson addresses the Christian doctrine of revelation by asking how theological truth claims can possibly be rooted in God’s incarnational self-communication. Engaging with the phenomenology of Martin Heidegger, Olson offers an interpretation of the Eucharist that grounds Christian knowledge in an embodied understanding of the sacrament.

The Many-Interacting-Worlds (MIW) approach to a quantum theory without wave functions proposed in [8] leads naturally to numerical integrators of the Schrödinger equation on comoving grids. As yet, little is known about concrete MIW models for more than one spatial dimension and/or more than one particle. In honour of Detlef Dürr, we report on a further development of the MIW approach to treat arbitrary degrees of freedom and provide a numerical proof of concept for ground states in 2d. The latter (...) is part of a systematic numerical study [22] that includes also 1d ground and excited states. With this step towards the treatment of higher degrees of freedom we hope to stimulate their further study. (shrink)

This book examines how enlightened Scottish social theorists c.1740 to c.1800 understood the origin and development of religion. Challenging scholarly disregard for the topic, it shows how most prominent thinkers of the Scottish Enlightenment thought deeply about the relationship between religion, human nature and historical change. The Scots viewed this relationship as an important strand within the study of the 'science of human nature' and the 'history of man.' The fruits of this investigation were a sophisticated and innovative account of (...) religious change that is characterized by a striking modernity and naturalism, even by the more devout theorists. The views of the literati surveyed here need to be incorporated into our larger histories of the 'science of religion' as much as they do into our understanding of the social theory of the Scottish Enlightenment.

This book is a joint effort of like-minded researchers to define the concept of process within a psychological setting. Although minor differences exist as regards choice of background theory, their common focus is on personality in a broad psychodynamic context. Their definition of personality rests on a series of test instruments that have been validated during decades of thorough and vigorous empirical work. These were originally designed to open up micro-processes underlying the adaptation to or construction of reality, and have (...) subsequently proven diagnostically efficient. Coming from both sides of the Atlantic, the contributors have their background in psychological as well as medical institutions. The contributions in the book are examples of a vital source sustaining our efforts to get a more profound understanding of the vicissitudes of the human mind. (shrink)

Is logic normative for reasoning? In the wake of work by Gilbert Harman and John MacFarlane, this question has been reduced to: are there any adequate bridge principles which link logical facts to normative constraints on reasoning? Hitherto, defenders of the normativity of logic have exclusively focussed on identifying adequate validity bridge principles: principles linking validity facts—facts of the form 'gamma entails phi'—to normative constraints on reasoning. This paper argues for two claims. First, for the time being at least, Harman’s (...) challenge cannot be surmounted by articulating validity bridge principles. Second, Harman’s challenge can be met by articulating invalidity bridge principles: principles linking invalidity facts of the form 'gamma does not entail phi' to normative constraints on reasoning. In doing so, I provide a novel defence of the normativity of logic. (shrink)

There are many echoes of Descartes and of other Cartesians in Locke's Essay. There is one particularly curious passage in the Essay which is clearly taken from the Regulae. This passage may be the one clear instance of the method of analysis and synthesis in Locke. Before I cite that passage, I want to raise a few questions about some of the claims in Professor Schouls’ paper. Professor Schouls is right to call attention to the need for some careful analysis (...) of the concept of experience in Locke. He concentrates upon the form experience takes initially : lf“he means temporally first, as with infants, the examples he cites do not fit this concept. The quotes he gives on p. 583 all refer to adult, sophisticated experience, not to the learning experience of children. There is a rudimentary genetic psychology in Locke's Essay and in his Education. He does list some brief order in the acquisition of ideas by children, in the very earliest stages of experience, e.g., with the foetus, “some faint ideas of hunger, and thirst, and warmth, and some pains” are acquired.

Although the theory of definability had many important antecedents—such as the descriptive set theory initiated by the French semi-intuitionists in the early 1900s—the main ideas were first laid out in precise mathematical terms by Alfred Tarski beginning in 1929. We review here the basic notions of languages, explicit definability, and grammatical complexity, and emphasize common themes in the theories of definability for four important languages underlying, respectively, descriptive set theory, recursive function theory, classical pure logic, and finite-universe logic. We review (...) the history of previous studies of the similarities and differences in the theories of definability of the first three of these four languages. A seminal role leading toward unification of the theories has been played by the separation principles introduced by Nikolai Luzin in 1927. Emphasizing analogies and driving toward further unification embracing finite-universe logic we concentrate on a simple example—the first and second separation principles for existential-universal first-order sentences . Using this as a test case for the fundamental problem of how to “finitize” arguments in classical pure logic to the finite-universe case, we are led to the analogous negative solution by using the theory of certain special graphs: a graph is - special for any positive integers m , n , p , q iff it is bipartite with m red points and n blue points and for every p -tuple of red points there is a blue point to which they are all connected . As an aside we introduce for further study a natural “Ramseyesque” increasing sequence A of positive integers, where A is the least positive integer n for which an -special graph exists. (shrink)

Moral reasoning traditionally distinguishes two types of evil:moral and natural. The standard view is that ME is the product of human agency and so includes phenomena such as war, torture and psychological cruelty; that NE is the product of nonhuman agency, and so includes natural disasters such as earthquakes, floods, disease and famine; and finally, that more complex cases are appropriately analysed as a combination of ME and NE. Recently, as a result of developments in autonomousagents in cyberspace, a new (...) class of interesting and importantexamples of hybrid evil has come to light. In this paper, it is called artificial evil and a case is made for considering it to complement ME and NE to produce a more adequate taxonomy. By isolating the features that have led to the appearance of AE, cyberspace is characterised as a self-contained environment that forms the essential component in any foundation of the emerging field of Computer Ethics. It is argued that this goes someway towards providing a methodological explanation of whycyberspace is central to so many of CE's concerns; and it isshown how notions of good and evil can be formulated incyberspace. Of considerable interest is how the propensity for anagent's action to be morally good or evil can be determined evenin the absence of biologically sentient participants and thusallows artificial agents not only to perpetrate evil but conversely to `receive' or `suffer from'it. The thesis defended is that the notion of entropy structure,which encapsulates human value judgement concerning cyberspace ina formal mathematical definition, is sufficient to achieve thispurpose and, moreover, that the concept of AE can be determinedformally, by mathematical methods. A consequence of this approachis that the debate on whether CE should be considered unique, andhence developed as a Macroethics, may be viewed, constructively,in an alternative manner. The case is made that whilst CE issues are not uncontroversially unique, they are sufficiently novel to render inadequate the approach of standard Macroethics such as Utilitarianism and Deontologism and hence to prompt the search for a robust ethical theory that can deal with them successfully. The name Information Ethics is proposed for that theory. Itis argued that the uniqueness of IE is justified by its beingnon-biologically biased and patient-oriented: IE is anEnvironmental Macroethics based on the concept of data entityrather than life. It follows that the novelty of CE issues suchas AE can be appreciated properly because IE provides a newperspective. In light of the discussion provided in this paper, it is concluded that Computer Ethics is worthy of independent study because it requires its own application-specific knowledge and is capable of supporting a methodological foundation, Information Ethics.
