Although irrationality always presupposes rationality, I think there are good arguments to claim that sometimes rationality presupposes irrationality.This paper tries to show how irrational action can support rationality in two ways: it can develop and preserve rationality. I also argue that sometimes the development and the conservation of rationality can only be realized by irrational action.

Exploring the history of the concept of 'rationality', Deborah K. Hakes argues that feminism should seek to develop a virtue theory of rationality.

The traditional views of science as the possessor of a special method, and as the epitome or apex of rationality, have come under severe challenges for a variety of historical, psychological, sociological, political, and philosophical reasons. As a result, many philosophers are either denying science its claim to rationality, or else casting about for a new account of its rationality. In this paper a defense of the traditional view is offered. It is argued that contemporary philosophical discussion regarding the rationality of science is plagued by a failure to distinguish among three different questions, all taken to be "the" question of the rationality of science. Once these questions are delineated, it becomes possible to answer one of them in such a way that the traditional link between science's rationality and its method is reestablished--although the scientific method is itself given a non-traditional rendering. In short, it is argued that there is a feature of science which is appropriately characterized as its method; that this method does in fact secure science's rationality; and that science is therefore correctly construed as preeminently rational. It is suggested in addition that the philosophy of science is itself best seen as a primarily epistemological activity, and consequently that a correction from the excessively historicist conception of recent philosophy of science is in order.

There is more rationality in our lives than there is in our philosophy. There is more morality in our lives than there is in our philosophy. Those claims undoubtedly are startling, perhaps even incomprehensible, given that the Western philosophical tradition from Plato on is devoted to rationality, in morality and everywhere else. The narrowly circumscribed account of rationality in that philosophical tradition—formal reason—is, however, the source of both claims. The formal reason of philosophy is rule-governed reasoning, the kind of inferential reasoning used in logic and mathematics. This view percolates through ordinary understandings of rationality as well, exemplified by the familiar use of the expression ..

This paper looks at the question of what form the requirements of practical rationality take. One common view is that the requirements of rationality are wide-scope, and another is that they are narrow-scope. I argue that the resolution to the question of wide-scope versus narrow-scope depends to a significant degree on what one expects a theory of rationality to do. In examining these expectations, I consider whether there might be a way to unify requirements of both forms into a single theory of rationality, and what the difficulties involved in doing so can teach us about the foundations of practical rationality.

According to one view about the rationality of belief, such rationality is ultimately nothing other than the rationality that one exhibits in taking the means to one’s ends. On this view, epistemic rationality is really a species or special case of instrumental rationality. In particular, epistemic rationality is instrumental rationality in the service of one’s distinctively cognitive or epistemic goals (perhaps: one’s goal of holding true rather than false beliefs). In my (2003), I dubbed this view the instrumentalist conception of epistemic rationality.

The tu quoque argument is the argument that since in the end rationalism rests on an irrational choice of and commitment to rationality, rationalism is as irrational as any other commitment. Popper's and Polanyi's philosophies of science both accept the argument, and have on that account many similarities; yet Popper manages to remain a rationalist whereas Polanyi decided for an irrationalist version of rationalism. This is more marked in works of their respective followers, W. W. Bartley III and Thomas S. Kuhn. Bartley declares the rationalist's very openness to criticism open to criticism, in the hope of rendering Popper's critical rationalism quite comprehensive. Kuhn makes rationality depend on the existence of an accepted model for scientific research (paradigm), thus rendering Polanyi's view of the authority of scientific leadership a sine qua non for scientific progress. The question raised here is, in what sense is a rationalist committed to his rationality, or an irrationalist to his specific axiom ? The tradition views only the life?long commitment as real. Viewing rationality as experimental open?mindedness, we may consider a rationalist unable to retreat into any life?long commitment ? even commitment to science. In this way the logic of the tu quoque argument is made irrelevant: anyone able to face the choice between rationality and commitment is already beyond such a choice; it is one thing to be still naïve and another ? and paradoxical ? thing to return to one's naïveté.

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.

Social science employs teleological explanations which depend upon the rationality principle, according to which people exhibit instrumental rationality. Popper points out that people also exhibit critical rationality, the tendency to stand back from, and to question or criticise, their views. I explain how our critical rationality impugns the explanatory value of the rationality principle and thereby threatens the very possibility of social science. I discuss the relationship between instrumental and critical rationality and show how we can reconcile our critical rationality with the possibility of social science if we invoke Popper’s conception of limited rationality and his indeterminism.

The dominant tradition in Western philosophy sees rationality as dictating. Thus rationality may require that we believe the best explanation and simple conceptual truths and that we infer in accordance with evident rules of inference. I argue that, given what we know about the growth of knowledge, this authoritarian concept of rationality leads to absurdities and should be abandoned. I then outline a libertarian concept of rationality, derived from Popper, which eschews the dictates and which sees a rational agent as one who questions, criticises, conjectures and experiments. I argue that, while the libertarian approach escapes the absurdities of the authoritarian, it requires two significant developments and an important clarification to be made fully consistent with itself.
