Carnap's philosophy is examined from new viewpoints, including three important distinctions: (i) language as calculus vs language as universal medium; (ii) different senses of completeness: (iii) standard vs nonstandard interpretations of (higher-order) logic. (i) Carnap favored in 1930-34 the "formal mode of speech," a corollary to the universality assumption. He later gave it up partially but retained some of its ingredients, e.g., the one-domain assumption. (ii) Carnap's project of creating a universal self-referential language is encouraged by (ii) and by the (...) author's recent work. (iii) Carnap was aware of (iii) and occasionally used the standard interpretation, but was not entirely clear of the nature of the contrast. (shrink)

: This essay explores some themes in use of a relativized Kantian a priori in the work of Thomas Kuhn and Michael Friedman. It teases out some shared and some divergent beliefs and attitudes in these two philosophers by comparing their characteristic questions and problems to the questions and problems that seem most appropriately to attend to an adequate understanding of games and their histories. It argues for a way forward within a relativized Kantian framework that is suggested but not (...) argued for in Friedman (2001): philosophers of science should move from a concern with unreason as meaninglessness to a concern with unreason as argumentative coercion. It ends with a few suggestions regarding a place for philosophy in the history of reason. (shrink)

The modem rationalist tradition initiated by Descartes has as one of its central tenets the independence of the human understanding from the senses. Regardless of the different ways in which independence from experience is understood, there is much common ground among the modem views on the a priori. Yet Kant, culminating this tradition, introduces an entirely new conception of the a priori never before articulated in the history of philosophy. This is the notion of elements in knowledge which are independent (...) of experience but nevertheless closely connected, in a special way, with experience.Although for Kant the a priori has a privileged position in the structure of knowledge - as it has for other modem rationalist philosophers - one of the most striking, and often neglected, aspect of his conception of the a priori is the great extent to which it is opposed to foundationalism.

This paper offers a refutation of J. C. Pinto de Oliveira's recent critique of revisionist Carnap scholarship as giving undue weight to two brief letters to Kuhn expressing his interest in the latter's work. First an argument is provided to show that Carnap and Kuhn are by no means divided by a radical mismatch of their conceptions of the rationality of science as supposedly evidenced by their stance towards the distinction of the contexts of discovery and justification. This is followed (...) by an argument to the effect that the fact that Carnap's own work concentrated on formal aspects of scientific theories does not licence the conclusion that he thought historical investigations and concerns irrelevant for what we nowadays would rightly call "philosophy of science".
