Two plausible claims seem to be inconsistent with each other. One is the idea that if one reasonably believes that one ought to fi, then indeed, on pain of acting irrationally, one ought to fi. The other is the view that we are fallible with respect to our beliefs about what we ought to do. Ewing’s Problem is how to react to this apparent inconsistency. I reject two easy ways out. One is Ewing’s own solution to his problem, which is to introduce two different notions of ought. The other is the view that Ewing’s Problem rests on a simple confusion regarding the scope of the ought-operator. Then, I discuss two hard ways out, which I label objectivism and subjectivism, and for which G.E. Moore and Bishop Butler are introduced as historical witnesses. These are hard ways out because both of these views have strong counterintuitive consequences. After explaining why Ewing’s Problem is so difficult, I show that there is conceptual room in-between Moore and Butler, but I remain sceptical whether Ewing’s Problem is solvable within a realist framework of normative facts.

I start by explaining what attitude-related reasons are and why it is plausible to assume that, at least in the domain of practical reason, there are such reasons. Then I turn to Raz’s idea that the practice of practical reasoning commits us to what he calls exclusionary reasons. Being excluded would be a third way, additional to being outweighed and being undermined, in which a reason can be defeated. I try to show that attitude-related reasons can explain the phenomena Raz appeals to equally well. Attitude-related reasons, however, are weighted against other reasons and, thus, don’t determine a third relation of defeat. On this basis, I voice some doubts about Raz’s conception of exclusionary reasons.

I argue that particularism (or holism) about reasons, i.e., the view that a feature that is a reason in one case need not be a reason in another case, is true, but uninterestingly so. Its truth is best explained by principles that govern a weaker notion than that of being a reason: one thing can be ‘normatively connected’ to something else without its being a reason for what it is normatively connected to. Thus, even though true, particularism about reasons does not support the particularist’s general idea that the normative domain is not governed by principles.

One of the guiding ideas of virtue epistemology is to look at epistemological issue through the lens of practical philosophy. The Gettier Problem is a case in point. Virtue epistemologists, like Sosa and Greco, see the shortcoming in a Gettier scenario as a shortcoming from which performances in general can suffer. In this paper I raise some doubts about the success of this project. Looking more closely at practical philosophy, will, I argue, show that virtue epistemology misconceives the significance of Gettier structures in the practical domain

Es wird versucht, die Stellung des Vindizierungsarguments im Gesamtzusammenhang des Induktionsproblems genauer festzulegen, und eine neue Sichtweise dieses Arguments als entscheidungstheoretisches Dominanzargument wird vorgeschlagen. Diese neue Interpretation bewährt sich in der Konfrontation mit alten Einwänden, doch zeigt sich schließlich, daß sich auch gegen diese Form des Vindizierungsarguments ein erfolgreicher Widerlegungsversuch führen läßt. Eine allgemeine Formulierung des vorgebrachten Einwandes erweist sich als stark genug, um auch die dem Vindizierungsargument analogen Rechtfertigungsversuche in anderen Bereichen zurückweisen zu können.
