scientific work

My scientific work has two main topics. Over the last few years I have done research on Ludwig Wittgenstein’s Tractatus Logico-philosophicus and its system. And before that, from 1989 until 1999, the main topic of my research was generalized quantification in relation to natural language semantics, perception reports, or in its own right.

My PhD thesis “Applied Quantifier Logics”, supervised by Johan van Benthem and Frank Veltman, defended March 1992, is a collection of articles, most of which have been published in Linguistics and Philosophy:

+ A Generalized Quantifier Logic for Naked Infinitives

  1. +Sums and Quantifiers

Michiel van Lambalgen and myself wrote an article on how a new form of substructural quantification, invented by Van Lambalgen, could be applied to the description of vision. In 2000, our article filled the entire Volume 23, Issue 1 of Linguistics and Philosophy:

  1. +A Logic of Vision

June 2011 I have published the book Passed over in Silence, on Wittgenstein’s Tractatus and its system.

In 2012 I have edited, with Catarina Dutilh Novaes, a Festschrift for Martin Stokhof, which can be found here. My contribution, called 'Philosophical Interactions', is a dialogue mainly about early Wittgenstein's view on Frege.

Since 2012 I regularly give presentations or lecture at the Radboud University, Nijmegen. As of September 2015, I will chair the Research Master Seminar Wittgenstein’s Views on Sense and Grammar.
