Martin Stokhof

This book provides a first introduction to two key systems that play a role in any variety or application of logic: classical propositional logic and classical predicate logic. It also contains pointers to variations and alternatives, to logics that deal with a wider range of concepts. This book provides examples of the application of logic to philosophical problems, and illustrates some of the philosophical problems that are raised by logic itself. This book aims to give the reader a first glimpse of the wide variety of tastes, smells, and textures that await them once they have trained their palate to appreciate the standard dishes of the logic cuisine.

Reading the Tractatus. And appreciating it The reception history of Wittgenstein’s Tractatus Logico-Philosophicus displays an impressive and persistent diversity. This paper explores possible sources of that diversity and locates them in different takes on the text and its context of origin, and in different perspectives of the readers. This hermeneutics is illustrated by a comparison of two views on the importance of ethics for an understanding of the Tractatus: that of Cora Diamond and the one developed by the authors in previous work.

In the first essay, Stokhof discusses the nature and presuppositions of the formal semantic project as such. He shows that considerations of so-called radical interpretation and the normativity of meaning force us to rethink the relationship between the meaning of a linguistic utterance and its interpretation in a way that is hardly compatible with this project. In the second essay, the author introduces the early Ludwig Wittgenstein as an obvious, if completely neglected, precursor of formal semantics. He discusses the systematic and, to a lesser extent, historical connections between the Tractatus and later formal semantics. From the similarities and differences found, it then draws conclusions regarding the contemporary status of this discipline at the interface of philosophy and the empirical sciences. Finally, the third study looks at formal semantics in terms of its contrast with Wittgenstein's later thinking about language. It attempts to answer the question of whether Wittgenstein's later reflections lead to a theory of linguistic meaning that could be a viable alternative to contemporary formal semantics.

The discussion of collective agency involves the reduction problem of the concept of a collective. Individualism and Cartesian internalism have long restricted orthodox theories and made them face the tension between an irreducible concept of a collective and ontological reductionism. Heterodox theories as functionalism and interpretationism reinterpret the concept of agency and accept it as realized on the level of a collective. In order to adequately explain social phenomena that have relations as their essence, in this paper we propose a relational, holistic account of collective agency and argue that functionalism and interpretationism can be integrated into such an account.

The end of philosophy? A Wittgensteinian perspective on the challenge of naturalism The paper addresses the challenges that naturalism poses for the humanities, and for philosophy in particular. After a general overview it takes as its starting point recent discussions on Wittgenstein’s metaphilosophy and argues that from Wittgenstein’s work on certainty, aesthetic experience and religious belief a notion of ‘non-discursive content’ can be extracted that may provide a new take on the naturalistic challenge.

In zijn artikel geeft Hans Radder een rijk en veelomvattend beeld van zijn ideeën over een aantal centrale aspecten van wetenschap en wetenschappelijke experimenten, en de rol die materiële realisatie, interpretatie en abstractie daarin spelen. Het is een uiteenzetting op een hoog niveau van abstractie, op basis van veel eerder gepubliceerd werk. Het is ook een beeld met grote samenhang: de diverse aspecten die de revue passeren zijn op allerlei wijzen aan elkaar gerelateerd. Als men uit zo’n samenhangend geheel twee elementen isoleert loopt men natuurlijk kans om allerlei subtiele aspecten over het hoofd te zien. Maar gezien de aard van dit commentaar, en de beknoptheid ervan, kan dat niet anders. ​In wat volgt willen we twee punten aan de orde stellen: de vraag wat de relatie is tussen abstracte begrippen zoals Radder die analyseert en betekenis; en de vraag in hoeverre het beeld dat Radder geeft specifiek is voor de natuurwetenschappen of ook repercussies heeft voor andere wetenschappen, in het bijzonder de taalwetenschap.
