13Erotetic Ignorance, Propositional Ignorance, and Questions of Significance. Reply to Christopher Willard‐KylePhilosophical Issues 35 (1): 195-198. 2026.In his reply to my book Ignorance: A Philosophical Study, Christopher Willard-Kyle zooms in on erotetic ignorance and the Significance Condition of my account of ignorance. Erotetic ignorance is lacking the answers to certain questions when the question is sound and when there is an answer to the question. Willard-Kyle shows that my arguments for the idea that erotetic ignorance reduces to propositional ignorance are wanting. In this response, I address each of his concerns about this claim and …Read more

14Norms and Significance in Ignorance. Reply to Duncan PritchardPhilosophical Issues 35 (1): 190-194. 2026.This is a reply to Duncan Pritchard's response to my critique of his normative account of ignorance. Pritchard suggests that I take a Normative Condition on board in my own account of ignorance. Pritchard's suggestion has drastic revisionary and deflationary implications for how we use words like “ignorance” and “ignorant”. I explain why I believe this is unnecessary: one can perfectly well be ignorant without displaying any kind of intellectual fault. Pritchard does convincingly show, though, t…Read more

8Can God Repent?In Jonathan Kvanvig (ed.), Oxford Studies in Philosophy of Religion, Volume 7, Oxford University Press Uk. pp. 190-212. 2016.Several passages in religious documents suggest that God sometimes repents. Few thinkers, however, have embraced the thought that God repents, mainly because it seems to conflict with being perfectly good and being omniscient. Two attempts to dissolve this conflict, open theism and Geachianism, are discussed. Finally, a different approach is proposed: even though God has full knowledge of the future free actions of his creatures, he does not have full knowledge of all his own future free actions…Read more

487Polarisatie en de CapitoolbestormingAlgemeen 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

18Vice Explanations for Conspiracism, Fundamentalism, and ExtremismReview of Philosophy and Psychology 15 (3): 885-907. 2023.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

22Life without God: An Outsider's Look at AtheismCambridge University Press. 2023.In this book, Rik Peels explores atheism from a new perspective that aims to go beyond the highly polarized debate about arguments for and against God's existence. Since our beliefs about the most important things in life are not usually based on arguments, we should look beyond atheistic arguments and explore what truly motivates the atheist. Are there certain ideals or experiences that explain the turn to atheism? Could atheism be the default position for us, not requiring any arguments whatso…Read more

5A philosophy of the humanitiesOxford University Press. 2025.This ground-breaking book opens up new vistas on the study of the humanities. Co-authored by three philosophers, it offers an in-depth exploration of a range of questions. For example, what, if anything, unifies scholarship in the humanities? Is it possible to attain objective truth in fields like history or literary studies or philosophy, or is everything a matter of perspective or standpoint? It is possible for fields in the humanities to make progress, and if so, how? And what should we make …Read more

59Against Doxastic CompatibilismPhilosophy 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

366Why responsible belief is blameless beliefJournal 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

134Normativity in studying conspiracy theory belief: Seven guidelinesPhilosophical 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

15A conceptual map of scientismIn Jeroen de Ridder, Rik Peels & Rene van Woudenberg (eds.), Scientism: Prospects and Problems, Oxford University Press. pp. 28-56. 2018.This chapter provides a conceptual map of scientism: an overview of the varieties of scientism and their relations. It argues that a plausible understanding of scientism is the thesis that the boundaries of natural science should be expanded in order to include academic disciplines or realms of life that are widely considered not to belong to the realm of science. Every participant in the debate on scientism should make clear which variety of scientism she or he adheres to or criticizes by speci…Read more

89Ignorance: a philosophical studyOxford 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

67Proper Social and Epistemic Expectations In Speech Exchange: Reply to GoldbergJournal 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

104New Developments in the Cognitive Science of Religion - The Rationality of Religious Belief (edited book)Springer. 2018.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

118The Metaphysics of DegreesEuropean 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

84The Cognitive Science of Religion, Philosophy and Theology: A Survey of the IssuesIn Hans van Eyghen, Rik Peels & Gijsbert van den Brink (eds.), New Developments in the Cognitive Science of Religion - The Rationality of Religious Belief, Springer. pp. 1-14. 2018.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

441Why Responsible Belief Is Permissible BeliefAnalytic 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

36The Social Dimension of Responsible Belief: Response to Sanford GoldbergJournal 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

221Ignorance is Lack of True Belief: A Rejoinder to Le MorvanPhilosophia 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

483What 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

353The ethics of belief and Christian faith as commitment to assumptionsReligious Studies 46 (1): 97-107. 2010.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
