Our current understanding of ‘fake news’ is not in good shape. On the one hand, this category seems to be urgently needed for an adequate understanding of the epistemology in the age of the internet. On the other hand, the term has an unstable ordinary meaning and the prevalent accounts which all relate fake news to epistemically bad attitudes of the producer lack theoretical unity, sufficient extensional adequacy, and epistemic fruitfulness. I will therefore suggest an alternative account of fake news that is meant as an explication rather than a traditional conceptual analysis of the term and that understands fake news solely from the consumer’s perspective. I will argue that this new account has the required theoretical unity, that it is epistemically highly fruitful, and that it is still very close to the ordinary usage. I conclude with addressing some of the main objections to this view.

In diesem Aufsatz räume ich mit einigen tiefsitzenden Vorurteilen gegen die methodologische Rolle von Intuitionen in der Philosophie auf. Zunächst wird gezeigt, dass Intuitionen eine zentrale Rolle als epistemische Gründe in Gedankenexperimenten spielen. Aber auch völlig andere Methoden des Philosophierens (wie etwa die Transzendentalpragmatik) kommen ohne Rekurs auf Intuitionen als Gründe letztlich nicht aus. Außerdem kläre ich über die Natur von Intuitionen und deren epistemologischen Status genauer auf. Intuitionen sind fundamentale Gründe, aber sie sind fehlbar, anfechtbar und lassen sich methodisch kontrollieren. Im letzten Teil des Aufsatzes zeige ich, dass Intuitionen auf eine besondere Weise unangreifbar sind: Alle gegen sie gerichteten skeptischen Argumente rekurrieren selbst an irgendeiner Stelle verdeckt auf Intuitionen. Skeptische Generalangriffe auf Intuitionen als valide Gründe untergraben sich also selbst.

Disrespect for the truth, the rise of conspiracy thinking, and a pervasive distrust in experts are widespread features of the post-truth condition in current politics and public opinion. Among the many good explanations of these phenomena there is one that is only rarely discussed: that something is wrong with our deeply entrenched intellectual standards of (i) using our own critical thinking without any restriction and (ii) respecting the judgment of every rational agent as epistemically relevant. In this paper, I will argue that these two enlightenment principles—the Principle of Unrestricted Critical Thinking and the Principle of Democratic Reason—not only conflict with what is rationally required from a purely epistemic point of view, but also have bad cognitive consequences in furthering the spread of conspiracy theories and undermining trust in experts. I will then explain in more detail why we should typically defer to experts without using any of our own reasons regarding the subject matter. Moreover, I will show what place this leaves for critical thinking and why it does not have the crazy consequences that the critics expect.

Diese Analytische Einführung behandelt die wichtigsten Grundfragen und -probleme der Erkenntnistheorie und enthält eine ausführliche Darstellung von Positionen und Argumenten aus der gegenwärtigen Diskussion. Sie richtet sich an Studierende der Philosophie und anderer Fachgebiete, bietet aber auch für philosophische Kenner eine gewinnbringende kritische Orientierung. Für die zweite Auflage wurde der Text vollständig überarbeitet, um die jüngsten Entwicklungen im Themenfeld zu berücksichtigen. Am Ende jedes Kapitels gibt es nun Studienfragen zur selbständigen Rekapitulation und kommentierte Hinweise auf wichtige neue und weiterführende Literatur. Im Anhang finden sich Vorschläge für thematisch fokussierte Lehrveranstaltungen auf der Grundlage dieses Buches. Behandelt werden u.a. die erkenntnistheoretischen Grundbegriffe (Überzeugung, Wahrheit, Wissen und Rechtfertigung) sowie unterschiedliche Antworten auf die Fragen nach der Struktur, dem Umfang und den Quellen menschlichen Wissens. Die spezifischen Wissensarten kommen ausführlich zur Sprache (neben der Wahrnehmung insbesondere apriorisches Wissen, Erinnerung, Selbstwissen sowie sozialer Wissenstransfer und nicht-deduktive Schlussverfahren). Ein besonderes Augenmerk liegt außerdem auf der Rolle der Erkenntnistheorie innerhalb der Philosophie sowie ihrem Verhältnis zu den Einzelwissenschaften.

The topic of this article is the dependency or, maybe, the interdependency of rationality and self-knowledge. Here two questions may be distinguished, viz. whether being rational is a necessary condition for a creature to have self-knowledge, and whether having self-knowledge is a necessary condition for a creature to be rational. After a brief explication of what I mean by self-knowledge, I deal with the first question. There I defend the Davidsonian position, according to which rationality is, indeed, a necessary condition for self-knowledge. In addition, I distinguish two aspects of rationality which I call basic and local rationality. After that I concentrate on the second question for the remaining larger part of this article. Here I proceed in two stages: first I examine whether self-knowledge is necessary for basic rationality, and then whether it is necessary for local rationality.

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 valuable. In my paper, I take these issues as a starting point for exploring the prospects of an alternative methodological approach that I call ‘alethic instrumentalism’. The core idea behind this approach is to start with a properly designed epistemic goal and then to develop a framework of instrumentally valuable methods oriented towards this goal. This results in a somewhat revisionary framework of newly constructed core epistemic terms. In the paper, I elucidate the foundations of this new framework and address a number of methodological and content-related objections to the approach.

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, I will argue that the preemption view does not leave room for rejecting an expert judgment simply because it is outrageous. Third and finally, I will argue that outrageous expert judgments are ambiguous. Whereas some of them should be rationally rejected by laypeople, others are true and rationally acceptable. So, being outrageous is not, in and of itself, a reason to reject the judgment. Finally, I will argue that there are resources available to the preemption view that enable the layperson to reject some but not all outrageous expert judgments. This is sufficient to overcome the challenge from outrageous expert judgments to the preemption view.

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. As I will argue in this paper, this kind of skepticism is well-motivated, does not undercut the conciliatory principle, but still poses a radical challenge to philosophy as a cognitive discipline. Moreover, I will argue that non-global skepticism that is still extensive undermines itself as well. The deeper reason for this is that this more modest kind of skepticism can only be motivated by the assumption that disagreement with philosophical peers is abundant and that we can identify peers only by relying on track-record arguments. But then one can argue for extensive meta-philosophical skepticism only if one presupposes that those philosophical beliefs that form the basis of track-record evaluations are justified. Here, the threat of self-defeat looms again. I will proceed by first defending the premises of this new anti-skeptical argument against standard objections from the literature. Second, I will show in more detail where the epistemic inconsistency arises in the argument for extensive meta-philosophical skepticism. I conclude with an assessment of the scope and the limits of my argument.

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 then argue that there is a genuine alternative to both views–the Preemption View (PV)–that fares substantially better in both respects. I will give an outline and a detailed defense of PV in the paper.

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 the egoist. The paper will explore the details of this difference.

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 contrast, the Preemption View claims that, when one discovers what an authority believes, it is not permissible to rely on any of one’s own reasons concerning the subject matter. The original version of this view, as proposed by Linda Zagzebski, has recently been severely criticized for recommending blind trust and for abandoning even minimal standards for critical thinking. In our paper, we defend a new version of the Preemption View—Defeatist Preemptionism—in a way that differs radically from Zagzebski’s. We argue that our view can be derived from certain widely accepted general epistemic principles. In particular, we claim that preemption can be identified as a special case of source sensitive defeat. Moreover, we argue that Defeatist Preemptionism does not lead to the undesirable consequences that critics ascribe to the Preemption View. The paper thus articulates the foundations and refinements of the Preemption View, such that it adequately captures the phenomenon of epistemic authority and the rational requirements related to it.

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, I will discuss alleged examples of unsafe knowledge. In Sect. 5, I will address alleged cases of safe belief that do not constitute knowledge for non-Gettier reasons. My overall goal is to show that there are no successful counterexamples to robust anti-luck epistemology and to highlight some major presuppositions of my reply.

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 to truth, is the most important dimension for disciplines with scientific ambitions. I will then argue that, on the one hand, veritic progress in philosophy is more significant than many current philosophers believe, but that, on the other hand, it also has severe limitations. I will offer an explanation of these limitations that suggests that the history of philosophy should play some role, though only a minor one, in systematic philosophy.

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 metaphysical explanation of its reliability. It will be argued that in the case of intuition the very demand of such an explanation is based on a category mistake.

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 traditionellen Erkenntnistheorie mit ihren Gegnern die versteckten Prämissen und Implikationen der traditionellen Perspektive transparenter machen. Mit Beiträgen von: Thomas Bartelborth, Peter Baumann, Sven Bernecker, Elke Brendel, Fred Dretske, Thomas Grundmann, Frank Hofmann, Dirk Koppelberg, Hilary Kornblith, Wolfgang Spohn, Catrin Misselhorn, Richard Schantz, Christiane Schildknecht, Oliver Scholz, Karsten Stüber, Marcus Willaschek, Michael Williams.

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. In this volume, the metaphilosophical reflection on experimental philosophy is brought yet another step forward by engaging some of its most renowned proponents and critics in a lively and controversial debate. In addition to that, the volume also contains original experimental research on personal identity and philosophical temperament, as well as state-of-the-art essays on central metaphilosophical issues, like thought experiments, the nature of intuitions, or the status of philosophical expertise. -/- This book was originally published as a special issue of Philosophical Psychology.
