• Was ist instrumentelle Irrationalität?
    Studia Philosophica: Jahrbuch Der Schweizerischen Philosoph Ischen Gesellschaft, Annuaire de la Société Suisse de Philosphie  68 85-104. 2009.
    In this paper, I start from the observation that there are obvious instances of instrumental irrationality, i.e. cases where subjects act knowingly against their strongest preferences. This observation raises an important question: Which facts determine the ‘strength’ of preferences? I consider a standard answer to this question – ‘revealed preference theory’– which turns out to be unsatisfactory. Then I turn to a more promising alternative: the ‘higher order theory’ of preference strength. But …Read more

    How do frogs represent their prey? This question has been the focus of many debates among proponents of naturalistic theories of content, especially among proponents of teleosemantics. This is because alternative versions of the teleosemantic approach have different implications for the content of frog representations, and it is still controversial which of these content ascriptions (if any) is the most adequate. Theorists often appeal to intuitions here, but this is a dubious strategy. In this …Read more

    Truthmakers: A tale of two explanatory projects
    Synthese 181 (3): 413-431. 2011.
    Truthmakers are supposed to explain the truth of propositions, but it is unclear what kind of explanation truthmakers can provide. In this paper, I argue that ‘truthmaker explanations’ conflate two different explanatory projects. The first project is essentially concerned with truth, while the second project is concerned with reductive explanation. It is the latter project, I maintain, which is really central to truthmaking theory. On this basis, a general account of truthmaking can be formulate…Read more

    Fred Dretske’s account of mental causation, developed in Explaining Behavior and defended in numerous articles, is generally regarded as one of the most interesting and most ambitious approaches in the field. According to Dretske, meaning facts, construed historically as facts about the indicator functions of internal states, are the structuring causes of behavior. In this article, we argue that Dretske’s view is untenable: On closer examination, the real structuring causes of behavior turn out …Read more

    Willensfreiheit und Aufmerksamkeit bei Descartes
    Zeitschrift für Philosophische Forschung 71 (1): 5-36. 2017.
    The claims about free will that Descartes makes in his writings seem, at first glance, to be inconsistent. In recent years, several authors have argued that we can dissolve the apparent contradiction by taking a closer look at the role that attention plays in Descartes’s theory of the processes of judging and deciding. Prima facie, this exegetical approach seems promising, thus its considerable influence is understandable. Nevertheless, I aim to show that the approach is doomed to failure, since…Read more

    It is often claimed that Realism about universals is problematic because it cannot account for the relation between particulars and universals without falling prey to ,,Bradley's regress". In this article, I consider four different versions of this regress argument (the semantic regress, the explanatory regress, the ,One over Many' regress, and the truthmaker regress), each based on a different ,regress-generating' assumption. I argue that none of these arguments succeeds in refuting Realism. St…Read more

    The Difference Between Moral and Rational “Oughts”: An Expressivist Account
    Ethical Theory and Moral Practice 15 (2): 159-174. 2012.
    Morality and rationality are both normative: the moral claim “you ought to help others” is a genuine normative judgment, as well as the rational maxim “you ought to brush your teeth twice a day”. But it seems that there is a crucial difference these two judgments. In the first part of this paper, I argue that this difference is to be understood as a difference between two kinds of normativity: demanding and recommending normativity. But the crucial task is, of course, to explain the difference. …Read more

    Beyond Verbal Disputes: The Compatibilism Debate Revisited
    Erkenntnis 79 (3): 669-685. 2014.
    The compatibilism debate revolves around the question whether moral responsibility and free will are compatible with determinism. Prima facie, this seems to be a substantial issue. But according to the triviality objection, the disagreement is merely verbal: compatibilists and incompatibilists, it is maintained, are talking past each other, since they use the terms “free will” and “moral responsibility” in different senses. In this paper I argue, first, that the triviality objection is indeed a …Read more
