Sometimes, learning about the origins of a belief can make it irrational to continue to hold that belief—a phenomenon we call ‘genealogical defeat’. According to explanationist accounts, genealogical defeat occurs when one learns that there is no appropriate explanatory connection between one’s belief and the truth. Flatfooted versions of explanationism have been widely and rightly rejected on the grounds that they would disallow beliefs about the future and other inductively-formed beliefs. After motivating the need for some explanationist account, we raise (...) some problems for recent versions of explanationism. Learning from their failures, we then produce and defend a more resilient explanationism. (shrink)

It is now standard in the literature on reasons and rationality to distinguish normative reasons from motivating reasons. Two issues have dominated philosophical theorising concerning the latter: (i) whether we should think of them as certain (non-factive) psychological states of the agent – the dispute over Psychologism; and (ii) whether we should say that the agent can Φ for the reason that p only if p – the dispute over Factivism. This paper first introduces a puzzle: these disputes look very (...) much like merely verbal disputes about the meaning of phrases like `S’s reason’ in motivating reasons ascriptions, and yet charity requires us to think that something substantive is afoot. But what? The second aim of the paper is to extract substantive theses from certain natural arguments for Psychologism and Anti-Factivism – theses which are versions of a controversial view of the nature and normative structure of rationality. The paper ends by arguing against these substantive theses on phenomenological and ethical grounds. The upshot is that proponents of Psychologism and Anti-Factivism are either engaged in the project of defending merely verbal theses or they’re engaged in the project of defending false substantive ones.

ABSTRACT A number of authors have recently advanced a ‘disjunctivist’ view of the rationalising explanation of action, on which rationalisations of the form ‘S A’d because p’ are explanations of a fundamentally different kind from rationalisations of the form ‘S A’d because she believed that p’. Less attempt has been made to explicitly articulate the case against this view. This paper seeks to remedy that situation. I develop a detailed version of what I take to be the basic argument against (...) disjunctivism, drawing on a framework of explanatory proportionality. The disjunctivist cannot reject this framework, I argue, because they need it to respond to another challenge, from psychological individualism. As I explain, however, the proportionality-based challenge is not in principle insurmountable, and I outline a number of ways in which a case for disjunctivism might be developed in response to it. The paper thus clarifies the dialectic around disjunctivism about the rationalisation of action and, specifically, what advocates of the view must do in order to make a compelling case for it.

Dieser Forschungsbericht gibt einen Überblick über die aktuelle Debatte über motivierende Gründe in der Handlungs- und Erkenntnistheorie. Folgende drei Fragen werden schwerpunktmäßig behandelt: a) Was für eine Art von Entität sind motivierende Gründe? b) Welche Beziehung besteht zwischen einer Handlung oder Einstellung und ihren motivierenden Gründen? c) Welche kognitiven Bedingungen gelten für die Zuschreibung motivierender Gründe?

In this paper I give a novel argument for the view that epistemic normative reasons (or evidence) need not be facts. I first argue that the nature of normative reasons is uniform, such that our positions about the factivity of reasons should agree across normative realms –– whether epistemic, moral, practical, or otherwise. With that in mind, I proceed in a somewhat indirect way. I argue that if practical motivating reasons are not factive, then practical normative reasons are not factive. (...) If it is possible to act rationally in the light of a falsehood, as I will say, then some good reasons must be falsehoods. The implication of this argument is perhaps surprising: for one to firmly establish the view that epistemic normative reasons are factive, one must discredit the view that practical motivating reasons are not factive.

Williamson (2000) appeals to considerations about when it is natural to say that a hypothesis is consistent with one’s evidence in order to motivate the claim that all and only knowledge is evidence. It is argued here that the relevant considerations do not support this claim, and in fact conflict with it.

On a widely held view, the canonical way to make sense of intentional actions is to invoke the agent's ‘motivating reasons’, where the claim that X did A for some ‘motivating reason’ is taken to be neutral on whether X had a normative reason to do A. In this paper, I explore a challenge to this view, drawing on Anscombe's ‘second-personal’ approach to the nature of action explanation.
