Instrumental Rationality

Does rationality require us to take the means to our ends? Intuitively, it seems clear that it does. And yet it has proven difficult to explain why this should be so: after all, if one is pursuing an end that one has decisive reason not to pursue, the balance of reasons will presumably speak against one's taking the means necessary to bring that end about. In this paper I propose a novel account of the instrumental requirement which addresses this problem. On the view I develop, the instrumental requirement is normative not because agents have reasons to comply with it, but because it is a normative standard intrinsic to intentional action—i.e., it is a standard that partly spells out what it is to exercise one's agency well.     

Epistemic Rationality

Many epistemologists and philosophers of science, especially those with “naturalist” inclinations, argue that if there is to be any such thing as normativity or rationality in these domains, it must be instrumental—roughly, a matter of goal satisfaction—rather than something involving normative “oughts” that are independent of the satisfaction of our epistemic, cognitive, or other ends. This paper argues that while such an instrumental conception of epistemic rationality is perfectly respectable, even insofar as it concerns specifically epistemic ends, it cannot be the whole story about such normativity. Rather, it must be accompanied by a “categorical,” goal‐independent sort of normativity that cannot be reduced to instrumental rationality, both because instrumental rationality itself depends on a noninstrumental relationship between a belief/claim/theory and the evidence that renders it rational, and because the epistemic rationality of many beliefs is independent of the goals of their believers.

Rationality As Conformity

We argue in favour of identifying one aspect of rational choice with the tendency to conform to the choice you expect another like-minded, but non-communicating, agent to make and study this idea in the very basic case where the choice is from a non-empty subset K of 2 ^A and no further structure or knowledge of A is assumed.     

Rationality and Judgment

Abstract: Philosophical/epistemic theories of rationality differ over the role of judgment in rational argumentation. According to the “classical model” of rationality, rational justification is a matter of conformity with explicit rules or principles. Critics of the classical model, such as Harold Brown and Trudy Govier, argue that the model is subject to insuperable difficulties. They propose, instead, that rationality be understood, ultimately, in terms of judgment rather than rules. In this article I respond to Brown's and Govier's criticisms of the classical model, and to the “judgment model” they propose in its place. I argue that that model is unable both to distinguish between rational and irrational judgment and to avoid recourse to rules, and is therefore inadequate as an account of rationality, critical thinking, or argument appraisal. More positively, I argue that an adequate account of rationality must include a place for both rules and judgment.     

Self-Knowledge and Rationality

The topic of this article is the dependency or, maybe, the interdependency of rationality and self-knowledge. Here two questions may be distinguished, viz. (1) whether being rational is a necessary condition for a creature to have self-knowledge, and (2) 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.

Comparativist Rationality and

US testing of nuclear weapons has resulted in about 800,000 premature fatal cancers throughout the globe, and the nuclear tests of China, France, India, Russia, and the UK have added to this total. Surprisingly, however, these avoidable deaths have not received much attention, as compared, for example, to the smaller number of US fatalities on 9-11-01. This essay (1) surveys the methods and models used to assess effects of low-dose ionizing radiation from above-ground nuclear weapons tests and (2) explains some of the epistemological and logical problems (with these methods and models) that have caused scientists to decide against health screening of the most likely test victims. It also (3) argues that, once the faulty presuppositions and question-begging frames about testing and screening are recognized, there are compelling arguments in favor of nuclear-test nations' screening fallout victims, at least among their citizens. Finally, it (4) suggests that logically and epistemically flawed fallout studies/recommendations against screening are more like to occur when scientists adopt a Laudan-style comparativist rationality, rather than when they adopt a metascience more like that of Kuhn and others.     

Rationality and reflection

Christine Korsgaard claims that an agent is less than fully rational if she allows some attitude to inform her deliberation even though she cannot justify doing so. I argue that there is a middle way, which Korsgaard misses, between the claim that our attitudes neither need nor admit of rational assessment, on the one hand, and Korsgaard's claim that the attitudes which inform our deliberation always require justification, on the other: an agent needs reasons to opt out of her concerns – not reasons to opt into them or to stay in. As long as an agent has no good reason to abandon some concern of hers, she is reasonable to harbour it, and to allow it to inform her view of what reasons she has. A rational agent must therefore have the capacity to form higher-order attitudes toward her concerns; but rationality only requires that she exercise that capacity when she has some good reason to do so.     

Rationality in Religion

Religion can be defined narrowly as belief in anthropomorphic supernatural beings. For Levy-Bruhl this meant that prelogical ‘mystic participation’ preceded true religion. For Donald Wiebe and others it means that philosophical-scientific rationality has been struggling to replace religion since the axial age. A broader definition of religion interprets rational post-axial theology as a development within religion, not a replacement of true religion. Both definitions are legitimate. The narrow definition highlights a tendency to superstition in religion. The broader definition recognizes the possibility of an evolution of religious thought.
