Summary Reporting on the 7th International Congress of Logic, Methodology, and Philosophy of Science, first the main topics and some organisational aspects of the congress are presented; the main part of the report focuses on recent developments in Philosophical Logic (Section 5), in particular the theory of so-called generalized quantifiers as presented at the congress. In addition, some background information on logical language analysis, its possible applications and consequences is provided.

Strong notions of free will are closely connected to the possibility to do otherwise as well as to an agent’s ability to causally influence her environment via her decisions controlling her actions. In this paper we employ techniques from the causal modeling literature to investigate whether a notion of free will subscribing to one or both of these requirements is compatible with naturalistic views of the world such as non-reductive physicalism to the background of determinism and indeterminism. We argue that (...) from a causal modeler’s perspective the only possibility to get both requirements consists in subscribing to reductive physicalism and indeterminism. (shrink)

The volume contains the written versions of all papers given at the workshop, divided into five chapters and followed by Alvin Goldman's replies in the sixth.

In this paper I investigate unification as a virtue of explanation. In the first part of the paper (sec. 1-2) I give a brief exposition of the unification account of Schurz and Lambert (1994) and Schurz (1999). I illustrate the advantages of this account in comparison to the older unification accounts of Friedman (1974) and Kitcher (1981). In the second part (sec. 3) I discuss several comments and objections to the Schurz-Lambert account that were raised by Weber and van Dyck (...) (2002), Gijsbers (2007) and de Regt (2005). In the third and final part (sec. 4), I argue that explanation should be understood as a prototype concept which contains nomic expectability, causality and unification as prototypical virtues of explanations, although none of these virtues provides a sufficient and necessary "defining condition" of explanation.El artículo analiza la unificación como virtud explicativa. En su primera parte hago una breve exposición del enfoque de la unificación de Schurz y Lambert (1994) y Schurz (1999). Ilustro las ventajas de este planteamiento sobre otros anteriores, como Friedman (1974) y Kitcher (1981). En la segunda parte (secc. 3)discuto varios comentarios y objeciones al enfoque Schurz-Lambert planteados por Weber y van Dyck (2002), Gijsbers (2007) y de Regt (2005). En la tercera y última parte (secc. 4) argumento que la explicación debería entenderse como un concepto prototipo que contiene la esperabilidad nómica, la causalidad y launificación como virtudes prototípicas de las explicaciones, aunque ninguna de estas virtudes ofrece una condición “definitoria”, suficiente y necesaria, de la explicación.

A SUMMARY IN ENGLISH [by Editor]The problem is to find out whether mathematical propositions are analytical, and if so, or if not, to what extent.Kant defined the analyticity in terms of Cartesian res extensa, exemplified by “A body is extended”, while he considered, because of such examples, mathematical propositions to be synthetic. The recent studies in set theory by Gödel, P.J.Cohen, etc., indicate, however, that such a proposition as the continuum hypothesis is certainly not “analytic (tautological)” in the strict sense (...) of logicists. Rather a small portion, comparatively speaking, of mathematical propositions must therefore be considered analytic relative to the definitions of fundamental conrepts in logic. Axioms, for example, are per definitionem non-analytic. Other problems that demand reöxaminations are, for instance: 1. Why is there only one unique series of the natural numbers? 2. On which ground is the factual eminence of Euclidean geometry to be founded? etc. The two assertions that mathematical propositions are analytic and that they are synthetic a priori are thus not at all contradictory; they are, to begin with, not even mutually exclusive Possibilities.

Donald Davidson's unified theory of language and action can be understood as a continuation of the traditional analytic approach within philosophy of language and action. In the following we give an outline of some of the main themes of his philosophy centered around his core theory of radical interpretation (RI). His theory of rationality, his thesis of the anomalousness of the mental, and the externalist approach in his model of triangulation all follow in a systematic way from RI. Yet, Davidson's (...) philosophy can also be seen as giving a new systematic elaboration of central perspectives of W,v.O Quine's theory of language. In order to follow Davidson's main theses one therefore has to clarify the main differences and correspondences between both approaches. (shrink)

The domain of pragmatics is to arrange in the architectonic of competences. Competences are to discriminate on the base of distinction between rule-following behaviour and action-rules. This can be understood as a critic of L. Wittgensteins conception of following a rule. The Frankfurter version of speechacttheory has argued - following partial K Bühler - that three fundamental properties (functions) of language can be identified: the representation of state of affaires, the generation of interpersonal relationship and the expression of intentional make (...) happen someone (Erlebnisse). Further dimensions and explications for concerning this properties shall be elaborated. Steps to constructive pragmatics can be gone. (shrink)

Ascriptive solidarity is a fundamental relationship in human societies. Sociologists have often stated this social fact but they have seldom explained this kind of solidarity. Karl Otto Hondrich has elaborated fundamental social laws which are useful for the explanation of the evolutionary dominance of ascriptive solidarity. In the context of sociological knowledge I intend - following this account - to sketch variations of ascriptive solidarity in an evolutionary perspective and to describe structural problems of social integration in modern societies.
