In Dynamics of Reason (2001), Michael Friedman uses the example of Galilean rectilinear inertia to support his defense of scientific rationality against post-positivist skepticism. However, Friedman’s treatment of the case is flawed, such that his model of scientific change fails to fit the historical evidence. I present the case of Galileo, showing how it supports Friedman’s view of scientific knowledge, but undermines his view of scientific change. I then suggest reciprocal iteration as an amendment of Friedman’s view that better accounts (...) for scientific change. (shrink)

In this article I discuss a recent argument due to Dan McArthur, who suggests that the charge that Michael Friedman’s relativised a priori leads to irrationality in theory change can be avoided by adopting structural realism. I provide several arguments to show that the conjunction of Friedman’s relativised a priori with structural realism cannot make the former avoid the charge of irrationality. I also explore the extent to which Friedman’s view and structural realism are compatible, a presupposition of McArthur’s argument. (...) This compatibility is usually questioned, due to the Kantian aspect of Friedman’s view, which clashes with the metaphysical premise of scientific realism. I argue that structural realism does not necessarily depend on this premise and as a consequence can be compatible with Friedman’s view, but more importantly I question whether Friedman’s view really implies mind dependence.

Kuhn’s account of scientific change is characterized by an internal tension between a naturalist vein, which is compatible with the revolutionary perspective on the historical development of science, and an aprioristic or Kantian vein which wants to secure that science is not an irrational enterprise. Kuhn himself never achieved to resolve the tension or even to deal with the terms of the problem. Michael Friedman, quite recently, provided an account which aspires to reconcile the revolutionary and the aprioristic elements of (...) the Kuhnian historiography by placing the latter in the neo-Kantian philosophical framework. In this paper, I suggest that Friedman manages to provide a convincing description of the structuration of scientific knowledge and, further, to present science as a rational enterprise. I argue that despite these virtues Friedman’s account faces a major problem with regard to the context of transcendental idealism which he is not willing to abandon. I also argue that discarding transcendental idealism in the way the philosophical perspective of John McDowell does, we can dispose of the flaws of Friedman’s account while retaining its virtues.

Friedman’s perspective on scientific change is a sophisticated attempt to combine Kantian transcendental philosophy and the Kuhnian historiographical model. In this article, I will argue that Friedman’s account, despite its virtues, fails to achieve the philosophical goals that it self-consciously sets, namely to unproblematically combine the revolutionary perspective of scientific development and the neo-Kantian philosophical framework. As I attempt to show, the impossibility of putting together these two aspects stems from the incompatibility between Friedman’s neo-Kantian conception of the role of (...) philosophy and the role of the notion of incommensurability, and the framework of transcendental idealism and the radical character of scientific revolutions. Hence, I suggest that pace Friedman and pace Kuhn’s own self-understanding, the Kuhnian theory of scientific revolutions cannot be seen as ‘Kantianism with moveable categories’ and consequently we should either abandon the notion of radical scientific revolution or place the Kuhnian account into another, non-Kantian philosophical framework.
