    Typically, expert judgments are regarded by laypeople as highly trustworthy. However, expert assertions that strike the layperson as obviously false or outrageous, seem to give one a perfect reason to dispute that this judgment manifests expertise. In this paper, I will defend four claims. First, I will deliver an argument in support of the preemption view on expert judgments according to which we should not rationally use our own domain-specific reasons in the face of expert testimony. Second, …Read more

    Global meta-philosophical skepticism (i.e. completely unrestricted skepticism about philosophy) based upon disagreement faces the problem of self-defeat since it undercuts its motivating conciliatory principle. However, the skeptic may easily escape this threat by adopting a more modest kind of skepticism, that will be called “extensive meta-philosophical skepticism”, i.e., the view that most of our philosophical beliefs are unjustified, except our beliefs in epistemically fundamental principles…Read more

    How to respond rationally to peer disagreement: The preemption view
    Philosophical Issues 29 (1): 129-142. 2019.
    In this paper, I argue that the two most common views of how to respond rationally to peer disagreement–the Total Evidence View (TEV) and the Equal Weight View (EWV)–are both inadequate for substantial reasons. TEV does not issue the correct intuitive verdicts about a number of hypothetical cases of peer disagreement. The same is true for EWV. In addition, EWV does not give any explanation of what is rationally required of agents on the basis of sufficiently general epistemic principles. I will …Read more

    Egoismus, Altruismus und die Furcht vor dem eigenen Tod. Ein Beitrag zur analytischen Existenzphilosophie
    Zeitschrift für Philosophische Forschung 72 (4): 465-491. 2018.
    In this paper I will argue that Bernard William’s theory of frustrated desires is superior to Tom Nagel's theory of deprivation in explaining when and why death is harmful to oneself. The model of frustrated desires will then be applied contrastively to the altruist and the egoist. Contrary to what one might expect, death is not a misfortune only to the egoist. The truth is more nuanced. Nevertheless, there is a significant difference between what death means to the altruist and what it means to…Read more

    Modern societies are characterized by a division of epistemic labor between laypeople and epistemic authorities. Authorities are often far more competent than laypeople and can thus, ideally, inform their beliefs. But how should laypeople rationally respond to an authority’s beliefs if they already have beliefs and reasons of their own concerning some subject matter? According to the standard view, the beliefs of epistemic authorities are just further, albeit weighty, pieces of evidence. In cont…Read more

    Knowledge from Forgetting
    Philosophy and Phenomenological Research (3): 525-540. 2017.
    This paper provides a novel argument for granting memory the status of a generative source of justification and knowledge. Memory can produce justified output beliefs and knowledge on the basis of unjustified input beliefs alone. The key to understanding how memory can generate justification and knowledge, memory generativism, is to bear in mind that memory frequently omits part of the stored information. The proposed argument depends on a broadly reliabilist approach to justification.

    Saving safety from counterexamples
    Synthese 197 (12): 5161-5185. 2018.
    In this paper I will offer a comprehensive defense of the safety account of knowledge against counterexamples that have been recently put forward. In Sect. 2, I will discuss different versions of safety, arguing that a specific variant of method-relativized safety is the most plausible. I will then use this specific version of safety to respond to counterexamples in the recent literature. In Sect. 3, I will address alleged examples of safe beliefs that still constitute Gettier cases. In Sect. 4,…Read more

    Standard Analytic Epistemology typically relies on conceptual analysis of folk epistemic terms such as ‘knowledge’ or ‘justification’. A cross-cultural and cross-linguistic perspective on this method leads to the worry that there might not be universally shared epistemic concepts, and that different languages might use folk notions that have different extensions. Moreover, there is no reason to believe that our epistemic common-sense terms pick out what is epistemically most significant or valua…Read more

    Progress and Historical Reflection in Philosophy
    In Marcel van Ackeren (ed.), Philosophy and the Historical Perspective, Oxford University Press. pp. 51-68. 2018.
    What is the epistemic significance of reflecting on a discipline’s past for making progress in that discipline? I assume that the answer to this question negatively correlates with that discipline’s degree of progress over time. If and only if a science is progressive, then what people think or argue in that discipline ceases to be up-to-date. In this paper, I will distinguish different dimensions of disciplinary progress and consequently argue that veritic progress, i.e. collective convergence …Read more

    Some hope for intuitions: A reply to Weinberg
    Philosophical Psychology 23 (4): 481-509. 2010.
    In a recent paper Weinberg (2007) claims that there is an essential mark of trustworthiness which typical sources of evidence as perception or memory have, but philosophical intuitions lack, namely that we are able to detect and correct errors produced by these “hopeful” sources. In my paper I will argue that being a hopeful source isn't necessary for providing us with evidence. I then will show that, given some plausible background assumptions, intuitions at least come close to being hopeful, i…Read more

    The nature of rational intuitions and a fresh look at the explanationist objection
    Grazer Philosophische Studien 74 (1): 69-87. 2007.
    In the first part of this paper I will characterize the specific nature of rational intuition. It will be claimed that rational intuition is an evidential state with modal content that has an a priori source. This claim will be defended against several objections. The second part of the paper deals with the so-called explanationist objection against rational intuition as a justifying source. According to the best reading of this objection, intuition cannot justify any judgment since there is no …Read more

    Wie sieht die korrekte Struktur der Rechtfertigung menschlichen Wissens aus? Welches sind ihre legitimen Quellen? Wie groß ist der Umfang unserer gerechtfertigten Meinungen? Von der normativen Erkenntnistheorie erhoffen wir uns Antworten auf diese und ähnliche Fragen. Allzu oft wird dabei übersehen, daß die Antworten ganz entscheidend davon abhängen, was wir unter 'Rechtfertigung' verstehen. Mit den Beiträgen einer internationalen Autorenschaft möchte das Buch durch die Konfrontation der traditi…Read more

    How reliabilism saves the apriori/aposteriori distinction
    Synthese 192 (9): 2747-2768. 2015.
    Contemporary epistemologists typically define a priori justification as justification that is independent of sense experience. However, sense experience plays at least some role in the production of many paradigm cases of a priori justified belief. This raises the question of when experience is epistemically relevant to the justificatory status of the belief that is based on it. In this paper, I will outline the answers that can be given by the two currently dominant accounts of justification, i…Read more

    Philosophen berufen sich in Gedankenexperimenten oft auf Intuitionen. Doch werden diese Intuitionen auch von anderen Philosophen oder von philosophischen Laien geteilt? Und durch welche Faktoren werden sie eigentlich bestimmt? Experimentelle Philosophen gehen solchen Fragen seit einigen Jahren mit empirischen Methoden auf den Grund. Ihre Ergebnisse sind mitunter verblüffend und haben für Aufsehen gesorgt. Der vorliegende Band lässt führende Vertreter und Gegner dieser wachsenden Bewegung zu Wort…Read more

    Reliabilism and the problem of defeaters
    Grazer Philosophische Studien 79 (1): 65-76. 2009.
    It is widely assumed that justification is defeasible, e.g. that under certain conditions counterevidence removes prior justification of beliefs. In this paper I will first (sect. 1) explain why this feature of justification poses a prima facie problem for reliabilism. I then will try out different reliabilist strategies to deal with the problem. Among them I will discuss conservative strategies (sect. 2), eliminativist stragies (sect. 3) and revisionist strategies (sect. 4). In the final sectio…Read more

    Bonjour‘s Self-Defeating Argument for Coherentism
    Erkenntnis 50 (2-3): 463-479. 1999.
    One of the most influential arguments for the coherence theory of empirical justification is BonJours a priori argument from the internalist regress. According to this argument, foundationalism cannot solve the problem of the internalist regress since internalism is incompatible with basic beliefs. Hence, coherentism seems to be the only option. In my article I contend that this argument is doomed to failure. It is either too strong or too weak. Too strong, since even coherentism cannot stop the…Read more

    Experimental Philosophy and its Critics (edited book)
    Routledge. 2012.
    Experimental philosophy is one of the most recent and controversial developments in philosophy. Its basic idea is rather simple: to test philosophical thought experiments and philosophers’ intuitions about them with scientific methods, mostly taken from psychology and the social sciences. The ensuing experimental results, such as the cultural relativity of certain philosophical intuitions, has engaged – and at times infuriated – many more traditionally minded "armchair" philosophers since then. …Read more
