In this paper I reply to Stefaan Cuypers' explication and critique of my views on rationality and critical thinking (Cuypers, 2004). While Cuypers' discussion is praiseworthy in several respects, I argue that it (1) mistakenly attributes to me a Humean view of (practical) reason, and (2) unsuccessfully argues that my position lacks the resources required to defend the basic claim that critical thinking is a fundamental educational ideal. Cuypers' analysis raises deep issues about the motivational character of reasons; I briefly (...) address this matter as well. (shrink)

Non-empirical principles have always been a subject of interest of philoso-phers. Authors from different times and traditions agree that principles such as analogy or simplicity are present in the scientific practice. The disagreement comes out when these authors affirm that these principles have an epistemic function, and when they try to present reasons in order to found this state-ment. The first goal of this paper is to describe these principles and to point out their methodological importance. The second goal is (...) to introduce the discussion between the two most important models of philosophical fundamentation – it means, the logicism and the psychologism. The last goal – the main one – is to defend that the non-empirical principals have, legitimately, an epistemic role in the scientific investigation. (shrink)

This paper considers two philosophical problems and their relation to science education. The first involves the rationality of science; it is argued here that the traditional view, according to which science is rational because of its adherence to (a non-standard conception of) scientific method, successfully answers one central question concerning science''s rationality. The second involves the aims of education; here it is argued that a fundamental educational aim is the fostering of rationality, or its educational cognate, critical thinking. The ramifications (...) of these two philosophical theses for science education are then considered, and a science education which takes reasons in science as its fundamental feature is sketched.

It is with some trepidation that I offer this critical review of Feyerabend's new book. I do not relish the prospect of getting involved in one of the nasty little fights Feyerabend picks with those who criticize his work. Nevertheless, Feyerabend's work cries out for critical attention. Of particular interest is the degree to which this new work deepens or enhances Feyerabend's earlier castigations of Reason. Fans of Feyerabend will be disappointed to learn that Feyerabend's philosophy is not deepened or (...) enhanced in any significant way, and that his responses to his critics are on the whole unconvincing.

In two recent papers, I criticized Ronald N. Giere's and Larry Laudan's arguments for 'naturalizing' the philosophy of science (Siegel 1989, 1990). Both Giere and Laudan replied to my criticisms (Giere 1989, Laudan 1990b). The key issue arising in both interchanges is these naturalists' embrace of instrumental conceptions of rationality, and their concomitant rejection of non-instrumental conceptions of that key normative notion. In this reply I argue that their accounts of science's rationality as exclusively instrumental fail, and consequently that their (...) cases for 'normatively naturalizing' the philosophy of science fail as well.

Unlike more standard non-normative naturalizations of epistemology and philosophy of science, Larry Laudan's naturalized philosophy of science explicitly maintains a normative dimension. This paper critically assesses Laudan's normative naturalism. After summarizing Laudan's position, the paper examines (1) Laudan's construal of methodological rules as 'instrumentalities' connecting methodological means and cognitive ends; (2) Laudan's instrumental conception of scientific rationality; (3) Laudan's naturalistic account of the axiology of science; and (4) the extent to which a normative philosophy of science can be naturalized. It (...) is concluded that Laudan's normative naturalism is as problematic as its non-normative naturalist cousins. (shrink)

Harvey Siegel's (1985) attempts to revive the traditional epistemological formulation of the rationality of science. Contending that "a general commitment to evidence" is constitutive of method and rationality in science, Siegel advances its compatibility with specific, historically attuned formulations of principles of evidential support as a virtue of his aprioristic candidate for science's rationality. In point of fact, this account is compatible with virtually any formulation of evidential support, which runs afoul of Siegel's claim that scientific beliefs must be evaluated (...) with respect to their rationality. The unwelcome consequence of Siegel's view is that most any belief, scientific or pseudoscientific, can be defended as rational. Indeed, if we want to furnish a warrant for rational choice, we must turn to the very historically informed principles of evidential support that are dismissed by Siegel as providing a misleading portrait of science's rationality.

In his review (Inquiry 32 [1989], pp. 343?69) of Paul Feyerabend's Farewell to Reason, Harvey Siegel makes a fairly simple point: Feyerabend provides a bad argument for a good cause. In particular, Siegel maintains that the argument suffers, first, from self?inflicted depreciation: having been rendered impotent by Feyerabend's views of objectivity and rationality, what claim to persuasion can his argument possibly hold? And second, the argument is said to be incoherent: instead of respecting and leaving alone diverse cultures and traditions (...) as required by his views, Feyerabend fails to honor the right of people in several ways by formulating from afar abstract principles of cultural autonomy. Having debunked the argument, what remains is at least a semblance of agreement when Siegel identifies a shared concern with the value of cultural diversity on a world?wide scale. In response to Siegel this paper argues: yes, in an important sense, Feyerabend's argument is admittedly impotent and admission of that is a mere matter of acuity and intellectual honesty; but no, the argument is not incoherent, nor is there even a shared concern with the preservation of traditions in non?Western cultures. In other words, misunderstanding runs deep: a rationalist's objective misapprehension of Feyerabend's rhetorical devices. From this criticism of Siegel's criticism an alternative account emerges. Farewell to Reason poses a simple, but deeply troubling question: do the success and the benefits of science and technology warrant or require a social arrangement which privileges the highly specialized development of certain human faculties at the expense of others? The response to Siegel concludes with a survey of more creative ways in which philosophy can and should take up Feyerabend's challenge. (shrink)

In his (1988), Brian Baigrie criticizes my earlier discussion of the rationality of science (Siegel 1985). In this response, I argue that (1) Baigrie misses the point of my tripartite distinction between different questions one can ask about science's rationality, (2) Baigrie's argument that the history of the development of methodological principles is crucial to philosophical discussion of the rationality of science is flawed, and (3) Baigrie's charge that my view is "anemic" rests on a failure to appreciate the point (...) of my tripartite distinction.

A aceitação ou a escolha de uma teoria científica por parte de uma comunidade científica é um evento ou processo central na dinâmica científica. É, também, um evento ou processo complexo –já que dele participam as teorias, a experiência e alguma forma de relação inferencial entre a teoria e a experiência.
