    Contextualism and the Factivity Problem
    Philosophy and Phenomenological Research 76 (3): 580-602. 2008.
    Epistemological contextualism ‐ the claim that the truth‐value of knowledge‐attributions can vary with the context of the attributor ‐ has recently faced a whole series of objections. The most serious one, however, has not been discussed much so far: the factivity objection. In this paper, I explain what the objection is and present three different versions of the objection. I then show that there is a good way out for the contextualist. However, in order to solve the problem the contextualist h…Read more

    Safety, Virtue, Scepticism: Remarks on Sosa
    Croatian Journal of Philosophy 45 (3): 295-306. 2015.
    Ernest Sosa has made and continues to make major contributions to a wide variety of topics in epistemology. In this paper I discuss some of his core ideas about the nature of knowledge and scepticism. I start with a discussion of the safety account of knowledge – a view he has championed and further developed over the years. I continue with some questions concerning the role of the concept of an epistemic virtue for our understanding of knowledge. Safety and virtue hang very closely together for…Read more
  • Molyneux's Questions
    In Ralph Schumacher (ed.), Perception and Reality: From Descartes to the Present, Mentis. pp. 168-187. 2004.
    More than 300 years ago, William Molyneux raised an important and puzzling question which still creates a lot of controversy. What is known as “Molyneux’s question“ was made famous by John Locke’s quote of Molyneux in the second edition of the Essay Concerning Human Understanding: “Suppose a Man born blind, and now adult, and taught by his touch to distinguish between a Cube, and a Sphere of the same metal, and nighly of the same bigness, so as to tell, when he felt one and t’other, which is the…Read more

    WAMs: Why Worry?
    Philosophical Papers 40 (2): 155-177. 2011.
    One of the most popular objections against epistemic contextualism is the so-called?warranted assertability? objection. The objection is based on the possibility of a?warranted assertability manoeuvre?, also known as a WAM. I argue here that WAMs are of very limited scope and importance. An important class of cases cannot be dealt with by WAMs. No analogue of WAMs is available for these cases. One should thus not take WAMs too seriously in the debate about epistemic contextualism.

    The possibility of knowledge attributions across contexts (where attributor and subject find themselves in different epistemic contexts) can create serious problems for certain views of knowledge. Amongst such views is subject—sensitive invariantism—the view that knowledge is determined not only by epistemic factors (belief, truth, evidence, etc.) but also by non—epistemic factors (practical interests, etc.). I argue that subject—sensitive invariantism either runs into a contradiction or has to …Read more

    Experiencing things together: What is the problem?
    Erkenntnis 66 (1-2): 9-26. 2007.
    Suppose someone hears a loud noise and at the same time sees a yellow flash. It seems hard to deny that the person can experience loudness and yellowness together. However, since loudness is experienced by the auditory sense whereas yellowness is experienced by the visual sense it also seems hard to explain how.

    2 sides of the Kantian justification of property and state
    Kant Studien 85 (2): 147-159. 1994.
    Kant's political philosophy in general is characterized by two aspects which sometimes compete with each other and sometimes supplement each other: an individualist element on the one hand and a social or "communitarian" element on the other hand. This paper deals with Kant's theory of private property. It attempts to show something that is usually overlooked in the secondary literature: that Kant has two, not just one argument for property. One is based on his theory of freedom and expresses th…Read more
