Reichenbach's Philosophy of Space and Time (1928) avoids most of the logical positivist pitfalls it is generally held to exemplify, notably both conventionalism and verificationism. To see why, we must appreciate that Reichenbach's interest lies in how mathematical structures can be used to describe reality, not in how words like 'distance' acquire meaning. Examination of his proposed "coordinative definition" of congruence shows that Reichenbach advocates a reductionist analysis of the relations figuring in physical geometry (contrary to common readings that attribute (...) to him a holistic conventionalism), while embracing a thoroughly holistic understanding of empirical confirmation (contrary to rival operationalist readings).

According to Roman Ingarden, transcendental idealism prevented Kant from "even undertaking an attempt" at elucidating freedom "in terms of the causal structure of the world." I show that this claim requires qualification. In a remarkable series of Critical-period Reflexionen (5611-4, 5616-9), Kant sketches a defense of the possibility of freedom that differs radically from his published ones by incorporating an indeterministic account of the phenomena. Anticipating Łukasiewicz, he argues that universal causal determination is consistent with an open future: if an (...) action is contingent, there is an infinite regress of determining causes, yet there is a prior time at which this infinite series of causes has not yet commenced. However, he concedes that on this account the unity of experience "cannot fully obtain in the case of free beings." The fact that Kant even contemplated the indeterministic theory may carry implications for interpreting the argument of the Second Analogy. (shrink)

Each of the three essays constituting the dissertation's body explores a theoretical approach to conceptual content, as well as to particular kinds of concepts. A concluding chapter defends a distinction between two varieties of intentionality. ;Chapter 1 identifies a distinctive model of intentionality in Locke's discussion of our "ideas of the sorts of substances." Properly understood, his doctrine of the "inadequacy" of substance-ideas reveals that the sort represented by such an idea isn't settled by the idea's descriptive content. The key (...) to his compromise between classificatory conventionalism and essentialism is an injunction to "rectify" each substance-idea, one that reflects a norm governing natural-historical inquiry. Interestingly, Locke regards the resulting picture of the natural kinds represented by substance-ideas as compatible with his descriptivist account of how the extensions of substance-names are fixed. ;Chapter 2 examines Gupta and Belnap's theory of "circular concepts," which likewise appeals to a semantic "revision rule." Besides promising to explain semantic paradox when applied to the concept of truth, their theory significantly liberalizes the framework of truth conditional semantics. I criticize the rationale behind that liberalization by investigating the significance attributed to the revision rule, and propose invoking pragmatic ideas to do justice to some of the theory's motivating intuitions. ;Chapter 3 first argues that Brandom's appeal to normatively characterized linguistic practice subserves two approaches to content: one expressivist and the other reductionist. The criterion of adequacy motivating his "inferentialist" reduction of contentfulness, I then argue, is one he should dismiss in view of his deflationism about truth. Moreover, Brandom fails to vindicate the priority of attributions of inferential norms over attributions of propositional content. This criticism doesn't affect the expressivist elucidation of intentional concepts resulting from Brandom's normative-pragmatic description of assertional practice. ;My conclusion draws on this elucidation to defend a distinction prefigured in my construal of Locke as divorcing the aboutness of substance-ideas from assessments of truth. I argue that we should distinguish between a "representational" kind of intentionality whose attribution subserves explanations of successful inductive and explanatory practices, and a "semantic" kind whose attribution makes explicit normative features of the essentially communicative practice of assertion.
