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 kommen und will die bislang überwiegend englischsprachige Debatte verstärkt in die deutsche Philosophie hineintragen.

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 internalist regress in any legitimate way. In order to demonstrate this claim I will discuss various coherentist strategies. Too weak, since, were coherentism able to stop the regress, the argument against foundationalism would collapse.

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.e. evidentialism and reliabilism. While for the evidentialist, experience is epistemically relevant only if it is used as evidence, the reliabilist requires that the reliability of the relevant process depends on the reliability of experiential processes. I will argue that the reliabilist account accommodates our pre-theoretic classifications much better. In the final part of my paper I will use the reliabilist criterion to defend the a priori—a posteriori distinction against recent challenges by Hawthorne and Williamson

According to the received view, externalist grounds or reasons need not be introspectively accessible. Roughly speaking, from an externalist point of view, a belief will be epistemically justified, iff it is based upon facts that make its truth objectively highly likely. This condition can be satisfied, even if the epistemic agent does not have actual or potential awareness of the justifying facts. No inner perspective on the belief-forming mechanism and its truth-ratio is needed for a belief to be justified. In my view, this is not the whole story. While I agree that introspective access to our reasons is a defining feature of justification for the access internalist, not the externalist, I will argue that even for the latter, some kind of introspective access is an epistemic desideratum. Yet, even given that I am right, the desirable might not be achievable for us. Recent psychological research suggests that we do not dispose of reliable introspection into the sources of our own beliefs. This seems to undermine the claim that we can introspectively know about the reasons upon which our beliefs are based. In this paper I will therefore additionally show why these results do not threaten the kind of introspective access desirable from an externalist point of view.

In this paper I will discuss Michael Williamss inferential contextualism – a position that must be carefully distinguished from the currently more fashionable attributer contextualism. I will argue that Williamss contextualism is not stable, though it avoids some of the shortcomings of simple inferential contextualism. In particular, his criticism of epistemological realism cannot be supported on the basis of his own account. I will also argue that we need not give up epistemological realism in order to provide a successful diagnosis of scepticism.

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.

Descriptions of Gettier cases can be interpreted in ways that are incompatible with the standard judgment that they are cases of justified true belief without knowledge. Timothy Williamson claims that this problem cannot be avoided by adding further stipulations to the case descriptions. To the contrary, we argue that there is a fairly simple way to amend the Ford case, a standard description of a Gettier case, in such a manner that all deviant interpretations are ruled out. This removes one major objection to interpreting our judgments about Gettier cases as strict conditionals.

Skeptical dream-arguments are intended as general challenges to our epistemic claims concerning the world. They argue that we can never rule out the possibility of merely dreaming what we believe to perceive. In my paper I will scrutinize whether any kind of such argument is sound. On my view, many versions of this argument are defective. They are either too weak to challenge all kinds of our epistemic claims or they rely on implausibly strong epistemic principles. More plausible versions of the argument can be rebutted by the results of recent empirical dream research. As I will argue, there is an introspective criterion for currently being awake. Nevertheless there is one version of the dream-argument, which I will call quasi-dream-argument, that survives all criticism and brings out the structure of a compelling skeptical argument very clearly.

According to Alvin Goldman, reliabilists need to distinguish between unconditionally and conditionally reliable processes. The latter category is used to account for processes such as reasoning or memory. In this paper, I will argue that Goldman’s account of conditional reliability needs substantial revision in two respects. First, conditional reliability must be reinterpreted in terms of dependent reliability to avoid serious problems. Second, we need a more liberal account that allows dependently reliable processes to operate not only on doxastic but also on non-doxastic input. Thinking this way advances the explanatory power of reliabilism significantly.

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.

Wenn von dem epistemischen Regreßargument die Rede ist, dann denkt man gewöhnlich an ein Argument für den erkenntnistheoretischen Fundamentalismus: Um einen drohenden Begründungsregreß zu vermeiden, muß man annehmen, daß es sogenannte basale Meinungen gibt, die nicht durch andere Meinungen (oder propositionale Zustände inferentiell gerechtfertigt werden, sondern unmittelbar gerechtfertigt sind. Das fundamentalistische Regreßargument ist jedoch nur eine mögliche Reaktion auf das zugrundeliegende epistemische Regreßproblem. Der Beitrag beschäftigt sich genauer mit den Bedingungen und Konsequenzen des skeptischen Regreßarguments und vertritt die These, daß sich mit Hilfe des Regreßarguments der Skeptizismus nicht rechtfertigen läßt

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 sowie unterschiedliche Antworten auf die Fragen nach der Struktur, dem Umfang und den Quellen menschlichen Wissens. Die spezifischen Wissensarten kommen ausführlich zur Sprache. Ein besonderes Augenmerk liegt außerdem auf der Rolle der Erkenntnistheorie innerhalb der Philosophie sowie ihrem Verhältnis zu den Einzelwissenschaften.
