Kiesewetter defends the normativity of rationality by presenting a new solution to the problems that arise from the common assumption that we ought to be rational. He provides a defence of a reason-response conception of rationality, an evidence-relative account of reason, and an explanation of structural irrationality in relation to these accounts.

If conduct must be wrongful in order to be justifiably criminalised, how should its wrongfulness be established? I examine a conception of wrongfulness put forward by A. P. Simester, which makes wrongfulness turn on whether the reasons favouring the performance of an action are, all things considered, defeated by the reasons against its performance. I argue that such a view can only generate appropriate substantive constraints in the context of criminalisation if it can distinguish between the sorts of reasons that (...) a verdict of wrongfulness, as a concept distinct from stupidity or selfishness, should attend to, and the sorts of reasons it should leave out. Assuming that this conception of wrongfulness should operate as a constraint on criminalisation in a liberal-democratic state, the only reasons it should include are other-regarding reasons. What matters is whether the agent commits an other-regarding wrong. This conception of wrongfulness helps us further to resolve fundamental questions concerning mala prohibita and the legitimate reach of any duty to obey the law. (shrink)

This paper examines causal theories of reference with respect to how plausible an account they give of non-physical natural kind terms such as ‘gene’ as well as of the truth of the associated theoretical claims. I first show that reference fixism for ‘gene’ fails. By this, I mean the claim that the reference of ‘gene’ was stable over longer historical periods, for example, since the classical period of transmission genetics. Second, I show that the theory of partial reference does not (...) do justice to some widely held realist intuitions about classical genetics. This result is at loggerheads with the explicit goals usually associated with partial theories of reference, which is to defend a realist semantics for scientific terms. Thirdly, I show that, contrary to received wisdom and perhaps contrary to physics and chemistry, neither reference fixism nor partial reference are necessary in order to hold on to scientific realism about biology. I pinpoint the reasons for this in the nature of biological kinds, which do not even remotely resemble natural kinds (i.e., Lockean real essences) as traditionally conceived. (shrink)

My dissertation is a systematic defense of the claim that what it is to be rational is to correctly respond to the reasons you possess. The dissertation is split into two parts, each consisting of three chapters. In Part I--Coherence, Possession, and Correctly Responding--I argue that my view has important advantages over popular views in metaethics that tie rationality to coherence (ch. 2), defend a novel view of what it is to possess a reason (ch. 3), and defend a novel (...) view about what it is to act and hold attitudes for normative reasons (ch. 4). In Part II--Foundationalism, Deception, and The Importance of Being Rational--I argue that foundationalists about epistemic rationality should think that the foundational beliefs are held for sufficient reasons (ch. 5), argue that my view solves the New Evil Demon problem for externalism (and solves a related and underapprieciated problem) (ch. 6), and argue that my view can vindicate the thought that we ought to be rational (ch. 7).

Ser eficaz a la hora de tomar los medios pertinentes para nuestros fines se ha considerado como uno de los aspectos paradigmáticos de la racionalidad. Sin embargo, reconocer la normatividad de la racionalidad instrumental parece implicar la problemática tesis de que uno debe tomar los medios apropiados para sus fines por el mero hecho de tener estos fines, con independencia de cuán irracionales o inmorales sean. En estas páginas defiendo una concepción de la racionalidad instrumental que permite a un mismo (...) tiempo reconocerla como normativa y afirmar que hay medios que uno no debería tomar aun cuando se proponga fines para los que son pertinentes.

Since it is hard to see how subjective rationality could be normative, a humbler, purely evaluative account of rationality’s importance has been suggested: rationality is a non-moral virtue, and rational action is good so far as it reveals that an agent ‘functions well’. This paper argues, however, that even this fallback position is threatened by ‘eccentric billionaire’ scenarios: sometimes, flouting purported coherence standards of rationality is maximally virtuous. In defense of the virtue account, I argue that a novel view of (...) rational constraints is called for: rationality requires a certain form of higher-order coherence – as considerations about instrumental coherence can show.

This paper focuses on the relation between epistemic reasons and the subject’s epistemic perspective. It tackles the questions of whether epistemic reasons are dependent on the perspective of the subject they are reasons for, and if so, whether they are dependent on the actual or the potential perspective. It is argued that epistemic reasons are either independent or minimally dependent on the subject’s epistemic perspective. In particular, I provide three arguments supporting the conclusion that epistemic reasons are not dependent on (...) the subject’s actual perspective. Furthermore, I show that variants of these arguments apply against popular views holding that epistemic reasons depend on the subject’s potential perspective, such as the view that epistemic reasons are facts that one is in a position to know.

John Cook Wilson (1849–1915) was Wykeham Professor of Logic at New College, Oxford and the founder of ‘Oxford Realism’, a philosophical movement that flourished at Oxford during the first decades of the 20th century. Although trained as a classicist and a mathematician, his most important contribution was to the theory of knowledge, where he argued that knowledge is factive and not definable in terms of belief, and he criticized ‘hybrid’ and ‘externalist’ accounts. He also argued for direct realism in perception, (...) criticizing both empiricism and idealism, and argued for a moderate nominalist view of universals as being in rebus and only ‘apprehended’ by their particulars. His influence helped swaying Oxford away from idealism and, through figures such as H. A. Prichard, Gilbert Ryle, or J. L. Austin, his ideas were also to some extent at the origin of ‘moral intuitionism’ and ‘ordinary language philosophy’ which defined much of Oxford philosophy until the second half of the twentieth-century. Nevertheless, his name and legacy were all but forgotten for generations after World War II. Still, his views on knowledge are with us today, being in part at work in the writings of philosophers as diverse as John McDowell, Charles Travis, and Timothy Williamson. (shrink)

What is the relation between what we ought to do, on the one hand, and our epistemic access to the ought-giving facts, on the other? In assessing this,it is common to distinguish ‘objective’ from ‘subjective’ oughts. Very roughly, on the objectivist conception what an agent ought to do is determined by ought-giving facts in such a way that does not depend on the agent’s beliefs about, or epistemic access to, those facts; whereas on the subjectivist conception, what an agent ought (...) to do depends on his beliefs. This paper defends the need for, and explicates, a third category of ‘ought’: ‘warranted oughts’. Section 1 introduces the distinction between objective and subjective ‘oughts’. Sections 2–3 draw attention to some serious problems with each. Section 4 examines, though rejects, a recent attempt to replace subjective ‘oughts’ with objective ‘wide-scope oughts’ operating on belief-action combinations. Section 5 explicates the notion of a warranted ‘ought’ and defends the account against some possible objections. The resulting a picture is one in which an adequate analysis of practical normativity requires both objective and warranted ‘oughts’. Section 6 concludes by responding to a worry about countenancing both. (shrink)

Objectivism is the view that how an agent ought to act depends on all kinds of facts, regardless of the agent’s epistemic position with respect to them. One of the most important challenges to this view is constituted by certain cases involving specific conditions of uncertainty—so-called three-options cases. In these cases it seems overwhelmingly plausible that an agent ought to do what is recommendable given her limited perspective, even though the agent knows that this is not objectively the best course (...) of action. The standard objectivist response to this challenge relies on a distinction between what one ought to do and what would be blameworthy or unreasonable to do. This response is affected by several problems. In this paper I introduce and defend an alternative objectivist response to the challenge. My proposal admits that in the relevant cases the agent ought to do what is recommendable given her perspective, but maintains that this diagnosis of the cases is fully compatible with objectivism. I argue that this proposal has several advantages over alternative accounts of the cases. (shrink)

There is a growing consensus, long maintained by Derek Parfit, that there is an important distinction between what we have reason to do on the one hand, and what it is rational for us to do on the other. Philosophers are now realising that there is a conceptual distinction between rationality and normativity. Given this distinction, it thus becomes a substantive question whether rationality is genuinely normative; that is, whether there is any reason to do what rationality requires. While some (...) philosophers have argued that we sometimes have reason to do what rationality requires, it is notoriously difficult to show that there are always universal and categorical reasons to do what rationality requires. But if it is not the case that there are always universal and categorical reasons to do what rationality requires, then rationality is not genuinely normative.This dissertation offers a vindication of the normativity of rationality. I maintain that there is a robust relation between rational requirements and normative reasons. In arguing for this claim, I develop what I call the reasons-sensitive view of rationality, according to which rational requirements are normative verdicts: they are second-order claims about what there is conclusive reason of rationality to do. This view explains why there are always universal and categorical reasons to be rational. So while we may not always have most reason to do what it is rational for us to do, there is always some reason—reasons of rationality—to do what it is rational for us to do. I then show how this reasons-sensitive view addresses and responds to what I diagnose to be the major sources of skepticism about the normativity of rationality. (shrink)

Rationality appears to have some intimate relation with normativity: exactly what relation is in dispute. John Broome devotes a chapter of his recent book to rebutting the view that rationality has 'true' normativity, which he equates with the kind of normativity that I call directivity. In particular, he offers a number of arguments against derivative accounts of thenormativity of rationality. In this paper I defend my instrumentalist account from those arguments. In so doing I bring into view the grounds of (...) a live positive defence of rationality’s servanthood to directivity. (shrink)
