  • SanderVerhaegh

    Sander Verhaegh studied Political Science in Nijmegen and Philosophy in Nijmegen, Groningen, and Sheffield. He received an NWO 'Duurzame Geesteswetenschappen' grant to conduct a PhD project. The topic of his project is the Benacerraf Dilemma, a problem concerned with the question of how one can combine a plausible epistemology with a consistent metaphysics in the philosophy of mathematics. He is especially interested in the way naturalistic philosophers deal with this dilemma. The project will be supervised by Jeanne Peijnenburg and Igor Douven. Sanders' Masters thesis was concerned with the Duhem-Quine thesis, the idea that hypotheses cannot be tested in isolation but only in conjunction with our background theories.

In recent papers, he argues that David Lewis has landed in a contradiction when, together with Rae Langton, he offered a definition of ‘intrinsic’, and that propositions are not sets of possible worlds. Together with Bob Hale, he is editing the volume Modality: Metaphysics, Logic, and Epistemology for Oxford University Press. Aviv will be visiting the project over October and December, 2009.

  • DavidOver

    David Over is a professor of psychology at Durham University. He completed a PhD in philosophy at Birkbeck College, University of London, where Dorothy Edgington was his supervisor, but he has worked for many years in the psychology of reasoning. His recent research (with his collaborators) aims to develop the new probabilistic paradigm in the psychology of reasoning and its support for a very close connection, in people’s judgments, between the probability of a natural language conditional and the conditional probability of the consequent given the antecedent. In further support of the new paradigm, he has most recently been studying (also with collaborators) the relation between indicative conditionals and disjunctions and also between indicative conditionals and conditional bets.
