Causality plays an important role in medieval philosophical writing: even before the rediscovery of Aristotle's major works, the created universe was seen as a rational manifestation of God's action. In the later Middle Ages, the dominant genre of medieval academic writing was the commentary on an authoritative work: Aristotle's Physics and Metaphysics were frequently commented on, and both contain a great deal of material on causation. So the nature of the philosophical and theological themes which were popular in the Middle (...) Ages led to an emphasis on causality. Writers studied the interrelationship of divine grace and natural processes, the role of the will in ethics, free will and determinism: all of these problems have an important causal component.

We consider the symbol grounding problem, and apply to it philosophical arguments against Cartesianism developed by Sellars and McDowell: the problematic issue is the dichotomy between inside and outside which the definition of a physical symbol system presupposes. Surprisingly, one can question this dichotomy and still do symbolic computation: a detailed examination of the hardware and software of serial ports shows this.
We start with the ambition -- dating back to the early days of the semantic web -- of assembling a significant portion human knowledge into a contradiction-free form using semantic web technology. We argue that this would not be desirable, because there are concepts, known as essentially contested concepts, whose definitions are contentious due to deep-seated ethical disagreements. Further, we argue that the ninetenth century hermeneutical tradition has a great deal to say, both about the ambition, and about why it (...) fails. We conclude with some remarks about statistics.

We show that, given standard assumptions about classical dynamical systems, Lewis' conception of possible worlds is incompatible with classical physics in that it would imply that all dynamical systems were integrable.
We compare the role of Cartesian assumptions in the symbol grounding problem and in the Myth of the Given: We argue that the Sellars–McDowell critique of the Myth of the Given and, in particular, its use of the concept of normativity can provide useful resources for responding to the symbol grounding problem. We also describe the concepts of normativity at work in computer science and cognitive science: We argue that normative concepts are pervasive in the sciences and that, in particular, (...) McDowell’s dichotomy between the normative space of reasons and the realm of nature is somewhat problematic. (shrink)
We start with Fodor's critique of cognitive science in "The mind doesn't work that way: The scope and limits of computational psychology": he argues that much mental activity cannot be handled by the current methods of cognitive science because it is nonmonotonic and, therefore, is global in nature, is not context-free, and is thus not capable of being formalized by a Turing-like mental architecture. We look at the use of nonmonotonic logic in the artificial intelligence community, particularly with the discussion (...) of the so-called frame problem. The mainstream approach to the frame problem is, we argue, probably susceptible to Fodor's critique; however, there is an alternative approach, due to McCain and Turner, which is, when suitably reformulated, not susceptible. In the course of our argument, we give a proof theory for the McCain-Turner system and show that it satisfies cut elimination. We have two substantive conclusions: first, that Fodor's argument depends on assumptions about logical form which not all nonmonotonic theories satisfy and, second, that metatheory plays an important role in the context of evolutionary accounts of rationality.

An Introduction to Modern European Philosophy , contains scholarly but accessible essays by nine British academics on Hegel, Schopenhauer, Kierkegaard, Marx, Nietzsche, Husserl, Heidegger, Sartre, Simone de Beauvoir, Maritain, Hannah Arendt, Habermas, Foucault, and the 'Events' of 1968. Written for English-speaking readers, it describes the varied traditions within 19th- and 20th-century European philosophy, reflecting the dynamism and plurality within the European tradition and presenting opposing points of view. It deals with both French and German philosophers, plus Kierkegaard, and is not (...) confined to any one school of thought. It has been purged of jargon but contains a glossary of important technical terms. There is a bibliography of further reading and website information at the end of each chapter. (shrink)
We compare Fresco’s analysis of the Turing machine-based notion of computation with that of others, in particular with functional programming and with the reversible computing paradigm of Toffoli and others. We conclude that, although much useful philosophical work can be done by the sort of analysis that Fresco proposes, there is, nevertheless, always likely to be a number of individually viable but different accounts of computation.
We examine Gerhard Ebeling's arguments against the use of logic in theology and find them unconvincing, mainly because Ebeling knows very little about logic as practiced.
We start with a example of assembler programming, and show how even at this low level the structure of the programming language does not directly mirror the structure of the hardware, but that it is also decisively influenced by the human practices surrounding computer use, and that assembly language gives a view of the hardware which is accommodated to human interests and capabilities. We give several historical examples and illustrate the changing pattern of mutual accommodation between human practices and computer (...) technology, and argue for a more explicitly dialectical and critical approach to the history and philosophy of programming.

We examine a series of disputations which Luther participated in towards the end of his career: we argue that these disputations show that Luther was very familiar with the tools of medieval formal logic, and continued to make positive theological use of them until the end of his life.
David Lewis' account of counterfactuals is based on a relation of comparative similarity between possible worlds. We investigate what this relation might amount to in the case where the possible worlds are trajectories of dynamic systems: for most dynamic systems, there are unexpected difficulties in defining the sort of relation that Lewis requires. The difficulties are related to a pervasive, but counter-intuitive, feature of dynamic systems called non-integrability.
