The final section of the book considers two features of the world which transcend the categories, existence and negation.

Rational agents are supposed to maximize expected utility. But what are the options from which they choose? I outline some constraints on an adequate representation of an agent’s options. The options should, for example, contain no information of which the agent is unsure. But they should be sufficiently rich to distinguish all available acts from one another. These demands often come into conflict, so that there seems to be no adequate representation of the options at all. After reviewing existing proposals (...) for how to construe decision-theoretic options and finding them all wanting, I suggest that our model of rational agents should include a special domain of ‘virtual’ option propositions to serve as formal objects of deliberation and choice.

Originally published in 1992. The history of Western philosophy can be seen as a battle between those that insist that the "physical universe" exists and those would claim that there is a much larger "world" which contains atemporal and nonspatial things as well. The central part of this book, and the battle, concerns the existence of universals. Starting with the mediaeval definition of the issue found in Porphry and Boethius, the author then considers modern and contemporary versions of the battle. (...) He concludes that what is at stake between naturalists and ontologists is the existence and nature of a number of important categories, like structures, relations, sets, numbers and so on. (shrink)

Frege's scathing comments on Mill on the empirical grounds of arithmetical truth are elaborated. The suggestion is made that some entities are ‘well-behaved' : if you perform two acts and then two more, the ‘result' will be that exactly four acts have occurred. How much it all matters or means is not further discussed.

Dieses Buch geht davon aus, dass eine moderne Hermeneutik als Theorie des Verstehens im begrifflichen Rahmen der gegenwärtigen Theorie des Geistes und der Semantik rekonstruiert werden sollte. Vor diesem theoretischen Hintergrund, der in einem eigenen Kapitel näher umrissen wird, soll die Geschichte der Hermeneutik neu gelesen werden. Dabei wird deutlich, dass diese Lesart vielfach neue historische Interpretationen zu entwickeln und die wichtigsten Stationen der Geschichte der Hermeneutik theoretisch auf neue Weise zu integrieren vermag. Über die hermeneutischen Positionen hinaus, die in (...) den bisherigen Gesamtdarstellungen auftauchen, werden auch Entwürfe diskutiert, die besonders unter geist-theoretischen Aspekten interessant sind, zum Beispiel die antike Hermeneutik, die Hermeneutik Max Webers, die Hermeneutik der logischen Empiristen und die naturalistische Hermeneutik. Vor allem aber wird belegt, dass die Geschichte der Hermeneutik teilweise zu großen Einsichten gelangt ist, an die eine moderne Hermeneutik anknüpfen kann. Das Buch wendet sich nicht nur an Spezialisten der Hermeneutik-Geschichte, sondern an alle Interessierten, denen das Schicksal der verstehenden Wissenschaften am Herzen liegt, und möchte ihnen eine Perspektive empfehlen, unter der sich der Status und die Autonomie der Geisteswissenschaften sowie ihr Bezug auf das Humane unter Heranziehung substantieller Theorien auf neue Weise würdigen lassen.

This book has grown out of eight years of close collaboration among its authors. From the very beginning we decided that its content should come out as the result of a truly common effort. That is, we did not "distribute" parts of the text planned to each one of us. On the contrary, we made a point that each single paragraph be the product of a common reflection. Genuine team-work is not as usual in philosophy as it is in other (...) academic disciplines. We think, however, that this is more due to the idiosyncrasy of philosophers than to the nature of their subject. Close collaboration with positive results is as rewarding as anything can be, but it may also prove to be quite difficult to implement. In our case, part of the difficulties came from purely geographic separation. This caused unsuspected delays in coordinating the work. But more than this, as time passed, the accumulation of particular results and ideas outran our ability to fit them into an organic unity. Different styles of exposition, different ways of formalization, different levels of complexity were simultaneously present in a voluminous manuscript that had become completely unmanageable. In particular, a portion of the text had been conceived in the language of category theory and employed ideas of a rather abstract nature, while another part was expounded in the more conventional set-theoretic style, stressing intui tivity and concreteness.

Magnetism in meta-semantics is the view that the meaning of our words is determined in part by their use and in part by the objective naturalness of candidate meanings. This hypothesis is commonly attributed to David Lewis, and has been put to philosophical work by Brian Weatherson, Ted Sider and others. I argue that there is no evidence that Lewis ever endorsed the view, and that his actual account of language reveals good reasons against it.

1. „Schwache“ oder „freie Menschen“? „Weil es aber doch einem nachdenkenden und forschenden Wesen anständig ist, gewisse Zeiten lediglich der Prüfung seiner eigenen Vernunft zu widmen, hierbei aber alle Parteilichkeit gänzlich auszuziehen, und so seine Bemerkungen anderen zur Beurteilung öffentlich mitzuteilen; so kann es niemanden verargt, noch weniger verwehrt werden, die Sätze und Gegensätze, so wie sie sich, durch keine Drohung geschreckt, vor Geschworenen von seinem eigenen Stande verteidigen können, auftreten zu lassen.“ These: Wer diesen Text kritisch liest, stutzt – (...) was sollen die „schwachen Menschen“ hier? Ist nicht das bizarre „schwacher“ durch „freier“ zu ersetzen? Kant verbindet mit der Gerichtshofmetapher die gegen die Politik der Machtsprüche des Absolutismus, aber auch gegen die Gesetzlosigkeit des „status naturalis“ gerichtete Freiheit der Richter und Geschworenen, nicht aber deren Schwäche. Erst im Staat unter Freiheitsgesetzen könne ein Gerichtshof eingerichtet werden – „Zu dieser Freiheit gehört denn auch, seine Gedanken, seine Zweifel, die man sich nicht selbst auflösen kann, öffentlich zur Beurteilung auszustellen, ohne darüber für einen unruhigen oder gefährlichen Bürger verschrieen zu werden [„durch keine Drohung geschreckt“] Das liegt schon in dem ursprünglichen Rechte der menschlichen Vernunft, welche keinen anderen Richter erkennt, als selbst wiederum die allgemeine Menschenvernunft, worin ein jeder seine Stimme hat.“ Die Freiheit bezieht sich auf den Bürgerstand der Menschen und ihre Freiheitsgesetze. Wir befinden uns im Bereich einer Rechtsinstitution – was soll da der Appell an die Schwäche? Gibt es einen bürgerlichen Stand der Schwachen? Nein. Das Ergebnis der Gerichtsverhandlung wird sein, dass weder Satz noch Gegensatz gilt oder dass beide gelten könnten. Nun kommt hinzu, dass Kant zuvor den Menschen charakterisiert, der zwischen These und Antithese hin- und herschwankt – ein schwacher Mensch, dem der nachdenkende und forschende Mensch entgegengesetzt wird, der nun entschlossen vor dem Gerichtshof erfahren will, wie es um die Ansprüche der beiden Parteien steht. Auch im nachfolgenden Text wird emphatisch dafür argumentiert, dass der Mensch das Problem der Antinomie und seine Auflösung in seiner eigenen Vernunft findet und daher „die Verantwortung [Beantwortung?] nicht von sich abweisen und auf den unbekannten Gegenstand schieben kann“.

Wolfgang Welsch examines global aestheticization phenomena, probes the relationship of aesthetics and ethics, and considers the broad relevance of aesthetics for contemporary thinking. He argues that modes of thought familiar from the aesthetic realm comprise fundamental paradigms for understanding todayÆs reality. The implications for specific and everyday issues are demonstrated in studies of architecture, advertising, the Internet, and our perception of the life world. Surgically precise, innovative, and, above all, relevant, this book is an essential resource, providing the analysis (...) of contemporary culture with philosophical bite. Aesthetics is to transcend itself, address the whole realm of aethesis, and hence enable orientation in the contemporary condition. Undoing aesthetics means releasing it from old cultural binds and giving it new ties with the future. (shrink)

Our senses provide us with information about the world, but what exactly do they tell us? I argue that in order to optimally respond to sensory stimulations, an agent’s doxastic space may have an extra, “imaginary” dimension of possibility; perceptual experiences confer certainty on propositions in this dimension. To some extent, the resulting picture vindicates the old-fashioned empiricist idea that all empirical knowledge is based on a solid foundation of sense-datum propositions, but it avoids most of the problems traditionally associated (...) with that idea. The proposal might also explain why experiences appear to have a non-physical phenomenal character, even if the world is entirely physical. (shrink)

A study of Jim Jones and the Peoples Temple. It features a prologue that considers the meaning of the tragedy for a post-Waco, post-9/11 world.

Concentrating on Weber's engagement with political issues and their influence over his more theoretical concepts, Mommsen offers a critical analysis of Weber's notion of democracy, distinguishing its liberal and elitist features.

In Plato's Meno , there is a famous discussion of desire and evil. This paper is not a contribution to Platonic scholarship, but a direct taking up of the issue whether someone can desire evil. One stock interpretation of the putative impossibility of desiring what is evil or bad is the interpretation which emphasizes an internal or conceptual tie between desire and good. This interpretation compares pairs of terms such as ‘fear—danger’, ‘belief—truth’ and ‘desire—good’. To fear something is to regard (...) it as, or believe that it is, dangerous ; to believe something is to regard it as, or believe it to be, true ; to desire something is to regard it as, to believe it to be, good. Since it is obvious that people believe things which are false, it is maintained that it is equally obvious that people may desire what is bad and fear what is harmless or of no danger. Let us call this interpretation of the doctrine that it is impossible to desire evil the weak thesis. The weak thesis allows what seems a plain fact of human reality, that people believe falsehoods, fear things that cannot harm them and desire things which are not good. Equally obviously, it allows that people fail to believe truths, fail to desire goods, and fail to fear things that are dangerous. On this weak interpretation, the manner in which wickedness to others and self-destructiveness are due to ignorance is that people are ignorant about the nature of things and ways of acting, ignorant about what it would be like to possess something or ignorant about what it would be like to do something or other.

Hilary Putnam has recently observed that the fact/value distinction has acquired a strength and pervasiveness in our culture that make it akin to an institution. 1 I take it he meant an institution in the sense that Taboo is an institution in some cultures, not in the sense that the Church is an institution in ours. Invoking the distinction is a widespread conversational gambit in social life, not only in academic discussions. ‘That's a value judgment’ and ‘That's emotive’ are to (...) be heard at dinner parties more often than ‘Pass the salt’.

D. M. Armstrong is an eminent Australian philosopher whose work over many years has dealt with such subjects as: the nature of possibility, concepts of the particular and the general, causes and laws of nature, and the nature of human consciousness. This collection of essays explores the many facets of Armstrong's work, concentrating on his more recent interests. There are four sections to the book: possibility and identity, universals, laws and causality, and philosophy of mind. The contributors comprise an international (...) group of philosophers from the United States, England and Australia. An interesting feature of the volume is that Armstrong himself has written responses to each of the essays. There is also a complete bibliography of Armstrong's writings. (shrink)

Gottlob Frege has exerted an enormous influence on the evolution of twentieth-century philosophy, yet the real significance of that influence is still very much a matter of debate. This book provides a completely new and systematic account of Frege's philosophy by focusing on its cornerstone: the theory of sense and reference. Two features distinguish this study from other books on Frege. First, sense and reference are placed absolutely at the core of Frege's work; the author shows that no adequate account (...) of the theory can avoid analysing the notion of thought that underpins it, or explaining how it has clarified our concept of judgement. Second, the theory is situated within the development of Frege's thought; the author reveals how the theory caused Frege to alter many of his fundamental views. In doing so the author presents a clearer picture of the problems the theory was intended to solve, and delineates more sharply the characteristic features of Frege's philosophy. (shrink)

Traditional logic as a part of philosophy is one of the oldest scientific disciplines. Mathematical logic, however, is a relatively young discipline and arose from the endeavors of Peano, Frege, Russell and others to create a logistic foundation for mathematics. It steadily developed during the 20th century into a broad discipline with several sub-areas and numerous applications in mathematics, informatics, linguistics and philosophy. While there are already several well-known textbooks on mathematical logic, this book is unique in that it is (...) much more concise than most others, and the material is treated in a streamlined fashion which allows the professor to cover many important topics in a one semester course. Although the book is intended for use as a graduate text, the first three chapters could be understood by undergraduates interested in mathematical logic. These initial chapters cover just the material for an introductory course on mathematical logic combined with the necessary material from set theory. This material is of a descriptive nature, providing a view towards decision problems, automated theorem proving, non-standard models and other subjects. The remaining chapters contain material on logic programming for computer scientists, model theory, recursion theory, Godel’s Incompleteness Theorems, and applications of mathematical logic. Philosophical and foundational problems of mathematics are discussed throughout the text. The author has provided exercises for each chapter, as well as hints to selected exercises. About the German edition: …The book can be useful to the student and lecturer who prepares a mathematical logic course at the university. What a pity that the book is not written in a universal scientific language which mankind has not yet created. - A.Nabebin, Zentralblatt. (shrink)
