    Polarisatie en de Capitoolbestorming
    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

    Against Doxastic Compatibilism
    Philosophy and Phenomenological Research 89 (3): 679-702. 2013.
    William Alston has argued that the so‐called deontological conception of epistemic justification, on which epistemic justification is to be spelled out in terms of blame, responsibility, and obligations, is untenable. The basic idea of the argument is that this conception is untenable because we lack voluntary control over our beliefs and, therefore, cannot have any obligations to hold certain beliefs. If this is convincing, however, the argument threatens the very idea of doxastic responsibilit…Read more

    Why responsible belief is blameless belief
    Journal of Philosophy 107 (5): 257-265. 2010.
    What, according to proponents of doxastic deontologism, is responsible belief? In this paper, we examine two proposals. Firstly, that responsible belief is blameless belief (a position we call DDB) and, secondly, that responsible belief is praiseworthy belief (a position we call DDP). We consider whether recent arguments in favor of DDP, mostly those recently offered by Brian Weatherson, stand up to scrutiny and argue that they do not. Given other considerations in favor of DDP, we conclude that…Read more

    Normativity in studying conspiracy theory belief: Seven guidelines
    Philosophical Psychology 36 (6): 1125-1159. 2023.
    This paper aims to provide clear guidelines for researchers studying conspiracy theory belief. It examines the meta-linguistic question about how we should conceptualize 'conspiracy theory' and its relationship to the evaluative question of how we should evaluate beliefs in conspiracy theories, addressing normative issues surrounding the meaning, use, and conceptualization of ‘conspiracy theory’, as well as how these issues might impact how researchers study conspiracy theories or beliefs in the…Read more

    Vice Explanations for Conspiracism, Fundamentalism, and Extremism
    Review of Philosophy and Psychology 1-23. forthcoming.
    In the literature on conspiracism, fundamentalism, and extremism, we find so-called vice explanations for the extreme behavior and extreme beliefs that they involve. These are explanations in terms of people’s character traits, like arrogance, vengefulness, closed-mindedness, and dogmatism. However, such vice explanations face the so-called situationist challenge, which argues based on various experiments that either there are no vices or that they are not robust. Behavior and belief, so is the …Read more

    Ignorance: a philosophical study
    Oxford University Press. 2023.
    a brief history of the study of ignorance. There is a lack of serious investigation into ignorance: apart from the apophatic tradition in the ancient world and the Middle Ages and the more recent fields of agnotology, philosophy of race, and feminist philosophy, ignorance itself has received little philosophical attention. It is then laid out how the field that one would expect to have studied ignorance in detail, namely, epistemology, has failed to do so. The chapter also explores why this coul…Read more

    Proper Social and Epistemic Expectations In Speech Exchange: Reply to Goldberg
    Journal of Philosophical Research 47 237-242. 2022.
    I first list what I consider to be the main virtues of Goldberg’s novel and challenging account of epistemic pressure in speech exchange. I then zoom in on proper doxastic responses to assertions in conversations and argue that they comprise four things: (1) one believes the position that is testified to rather than just seeking, ensuring, trying, or aiming to believe the testifier on that proposition; (2) one believes the testifier; in other words, one wrongs the speaker not only if one disbeli…Read more

    The Metaphysics of Degrees
    European Journal of Philosophy 26 (1): 46-65. 2018.
    Degree-sentences, i.e. sentences that seem to refer to things that allow of degrees, are widely used both inside and outside of philosophy, even though the metaphysics of degrees is much of an untrodden field. This paper aims to fill this lacuna by addressing the following four questions: [A] Is there some one thing, such that it is degree sensitive? [B] Are there things x, y, and z that stand in a certain relation to each other, viz. the relation that x has more y than z? [C] In those cases in …Read more

    It is widely thought that the cognitive science of religion may have a bearing on the epistemic status of religious beliefs and on other topics in philosophy of religion. Epistemologists have used theories from CSR to argue both for and against the rationality of religious beliefs, or they have claimed that CSR is neutral vis-à-vis the epistemic status of religious belief. However, since CSR is a rapidly evolving discipline, a great deal of earlier research on the topic has become dated. Further…Read more

    Cognitive Science of Religion is still a rather young discipline. Depending on what one deems to be the first paper or book in the field, the discipline is now almost forty or almost thirty years old. Philosophical and theological discussion on CSR started in the late 2000s. From its onset, the main focus has been the epistemic consequences of CSR, and this focus is dominant even today. Some of those involved in the debate discussed the relevance of CSR for further issues in philosophy of religi…Read more

    What is ignorance?
    Philosophia 38 (1): 57-67. 2010.
    This article offers an analysis of ignorance. After a couple of preliminary remarks, I endeavor to show that, contrary to what one might expect and to what nearly all philosophers assume, being ignorant is not equivalent to failing to know, at least not on one of the stronger senses of knowledge. Subsequently, I offer two definitions of ignorance and argue that one’s definition of ignorance crucially depends on one’s account of belief. Finally, I illustrate the relevance of my analysis by paying…Read more

    Why Responsible Belief Is Permissible Belief
    with Anthony Booth
    Analytic Philosophy 55 (1): 75-88. 2014.
    This paper provides a defence of the thesis that responsible belief is permissible rather than obliged belief. On the Uniqueness Thesis (UT), our evidence is always such that there is a unique doxastic attitude that we are obliged to have given that evidence, whereas the Permissibility Thesis (PT) denies this. After distinguishing several varieties of UT and PT, we argue that the main arguments that have been levied against PT fail. Next, two arguments in favour of PT are provided. Finally, two …Read more

    The Social Dimension of Responsible Belief: Response to Sanford Goldberg
    Journal of Philosophical Research 44 79-88. 2019.
    Goldberg has argued in several writings of his that our social context is crucial in determining whether we believe responsibly or not. In this reply to his criticisms, I explore whether my Influence Account of responsible belief can do justice to this social dimension of responsible belief. I discuss the case of Nancy the scientist, that of Fernando the doctor, and that of Janice who promises Ismelda to shovel her lane. I argue that the core solution to the challenges these cases provide is to …Read more

    Ignorance is Lack of True Belief: A Rejoinder to Le Morvan
    Philosophia 39 (2): 345-355. 2011.
    In this paper, I respond to Pierre Le Morvan’s critique of my thesis that ignorance is lack of true belief rather than absence of knowledge. I argue that the distinction between dispositional and non-dispositional accounts of belief, as I made it in a previous paper, is correct as it stands. Also, I criticize the viability and the importance of Le Morvan’s distinction between propositional and factive ignorance. Finally, I provide two arguments in favor of the thesis that ignorance is lack of tr…Read more

    In this paper I evaluate Zamulinski’s recent attempt to rebut an argument to the conclusion that having any kind of religious faith violates a moral duty. I agree with Zamulinski that the argument is unsound, but I disagree on where it goes wrong. I criticize Zamulinski’s alternative construal of Christian faith as existential commitment to fundamental assumptions. It does not follow that we should accept the moral argument against religious faith, for at least two reasons. First, Zamulinski’s C…Read more

    Responsible belief and epistemic justification
    Synthese 194 (8): 2895-2915. 2017.
    For decades, philosophers have displayed an interest in what it is to have an epistemically justified belief. Recently, we also find among philosophers a renewed interest in the so-called ethics of belief: what is it to believe responsibly and when is one’s belief blameworthy? This paper explores how epistemically justified belief and responsible belief are related to each other. On the so-called ‘deontological conception of epistemic justification’, they are identical: to believe epistemically …Read more

    Hume’s Law Violated?
    Journal of Value Inquiry 48 (3): 449-455. 2014.
    Introduction: Prinz’s SentimentalismMany ethicists claim that one cannot derive an ought from an is. In others words, they think that one cannot derive a statement that has prescriptive force from purely descriptive statements. This thesis plays a crucial role in many theoretical and practical ethical arguments. Since, according to many, David Hume advocated a view along these lines, this thesis has been called ‘Hume’s Law’. In this paper, I adopt this widespread terminology, whether or not Hume…Read more

    Whether responsibility for actions and omissions requires the ability to do otherwise is an important issue in contemporary philosophy. However, a closely related but distinct issue, namely whether doxastic responsibility requires the ability to believe otherwise, has been largely neglected. This paper fills this remarkable lacuna by providing a defence of the thesis that doxastic responsibility entails the ability to believe otherwise. On the one hand, it is argued that the fact that unavoidabi…Read more
