    The extreme actor's perspective and why it matters for explanation
    with Jaron Harambam
    In Rik Peels & Lorne Dawson (eds.), Explaining Extreme Belief and Behaviour, Oxford University Press. 2026.
    This chapter argues that the perspective of extreme actors, such as conspiracy theorists, fundamentalists, extremists, and terrorists, is necessary both for understanding them and for arriving at relevant explanations of their thoughts, emotions, and behavior. Their perspective is important not only as source of information (in the context of discovery) but also for falsifying or validating findings (in the context of justification). Whereas one can find this position in applied social science r…Read more

    Mindsets and Narratives: A Commentary on Quassim Cassam’s Extremism (review)
    Critical Studies on Terrorism 15 (4): 1026-1031. 2022.
    In his newest book, Extremism (Cassam 2022), philosopher Quassim Cassam brings together and analyses many different concepts in extremism studies, such as ideology, violence, radicalisation, grievances, counternarratives, fanaticism, radicalism, and fundamentalism. Central to the book is the distinction between three different types of extremism: ideological, methods, and psychological extremism. This distinction illuminates the different ways in which the term is used and can be used to identif…Read more

    Three Transparency Principles Examined
    Journal of Philosophical Research 44 111-128. 2019.
    This paper derives, from Richard Moran’s work, three different accounts of doxastic Transparency—roughly, the view that when a rational person wants to know whether she believes that p, she directs her attention to the truth-value of p, not to the mental attitude she has vis-à-vis p. We investigate which of these is the most plausible of the three by discussing a number of examples. We conclude that the most plausible account of Transparency is in tension with the motivation behind Transparency …Read more

    Anscombe's Approach to Rational Capacities
    In Jeanne Peijnenburg & Sander Verhaegh (eds.), Women in the History of Analytic Philosophy, Springer. pp. 191-216. 2022.
    Reigning orthodoxy in the philosophical study of human rational capacities, such as being able to act intentionally and to reason, is to characterize them in causal psychological terms. That is, to analyze these capacities in terms of mental states and their causal relations. It is against this background that the work of G.E.M. Anscombe has gained renewed interest. The main goal of this chapter is twofold. First, I will explicate Anscombe’s philosophical approach by analyzing her account of int…Read more

    Polarisatie en de Capitoolbestorming
    with Rik Peels
    Algemeen Nederlands Tijdschrift voor Wijsbegeerte 116 (1): 4-23. 2024.
    Polarization and the Insurrection: The relation between identity and ideology in violent right-wing extremism The Capitol Hill Insurrection on January 6, 2021, in Washington has been, to many, a shocking and inconceivable event. On the face of it, far right ideologies, both in their extreme and radical varieties seem to play a crucial role here. Evidence from interviews with insurrectionists, however, suggests otherwise. Research on polarization in the United States and on radicalization into vi…Read more

    Transparent emotions? A critical analysis of Moran's transparency claim
    Philosophical Explorations 18 (2): 246-258. 2015.
    I critically analyze Richard Moran's account of knowing one's own emotions, which depends on the Transparency Claim for self-knowledge. Applied to knowing one's own beliefs, TC states that when one is asked “Do you believe P?”, one can answer by referencing reasons for believing P. TC works for belief because one is justified in believing that one believes P if one can give reasons for why P is true. Emotions, however, are also conceptually related to concerns; they involve a response to somethi…Read more

    Transparency and Commitment: the Case of Substantial Self-Knowledge
    In Adam Andreotta & Benjamin Winokur (eds.), New perspectives on transparency and self-knowledge, Routledge. pp. 166-191. 2025.
    In this chapter, I defend a transparency account of substantial self-knowledge against the self-interpretation account. First, I question how such self-interpretation should proceed without taking up at least some of the perspectives of the attitudes at issue. I argue that the inability to assess our attitudes from a detached perspective is not just a matter of epistemic access but relates to the nature of substantial attitudes themselves. Because they are connected to a person’s conception of t…Read more

    Substantial Self-Knowledge and the Necessity of Avowal
    Journal of Value Inquiry 58 (4). 2024.
    A central intuition regarding self-knowledge is that if I say (or think) that I believe that it is raining – to use a familiar example – I do not merely state a fact about my mental life but also express my view of the world: I take it to be the case that it is raining. The notion of avowal is supposed to capture this duality of perspectives: whilst occupying one’s first-person perspective, one self-attributes a mental attitude, which is a fact that is supposed to be true independent of one’s ow…Read more
