It is commonplace for philosophers to distinguish mere truths from truths that perspicuously represent the world's structure. According to a popular view, the perspicuous truths are supposed to be metaphysically revelatory and to play an important role in the accounts of law-hood, confirmation, and linguistic interpretation. Yet, there is no consensus about how to characterize this distinction. I examine strategies developed by Lewis and by Sider in his Writing the Book of the World which purport to explain this distinction in (...) terms of vocabulary: the truths that represent the world perspicuously have better, joint-carving vocabulary. I argue that the distinction between a perspicuous and mere truth concerns both the vocabulary of the sentence and its grammar. I then show that the collective motivations for distinguishing perspicuous from mere truths do not allow Lewis and Sider to properly impose constraints on grammar. (shrink)

Rudolf Carnap defended two quite different critiques of traditional philosophy: in addition to the much discussed verifiability criterion, he also proposed a critique based upon "formalizability." Formalizability rests upon the principle of tolerance plus an acceptance of a linguistic methodology. Standard interpreters of Carnap (e.g., [7] and [8]) assume that the principle of tolerance (and, hence, formalizability) gains its argumentative support from verificationism. Carnap, in fact, kept the two critiques separate and independent. Indeed, verificationism is even, in spirit, inconsistent with (...) tolerance. If the formalizability approach is emphasized, traditional metaphysics is reconstructed, not banished. Philosophical disputes remain rationally decidable, but metatheoretical in nature. Two results follow: Carnap's metaphilosophy cannot be rejected merely on the basis of rejections of verifiability. Second, Carnap's conclusion that all philosophy concerns language provides no reason for despair. (shrink)

On the now dominant Quinean view, metaphysics is about what there is. Metaphysics so conceived is concerned with such questions as whether properties exist, whether meanings exist, and whether numbers exist. I will argue for the revival of a more traditional Aristotelian view, on which metaphysics is about what grounds what. Metaphysics so revived does not bother asking whether properties, meanings, and numbers exist (of course they do!) The question is whether or not they are fundamental.

This thesis evaluates and compares two versions of neutral monism, one developed by William James and the other by Bertrand Russell. Both argued against Cartesianism in favour of a "subjectless given" as the basic stuff which constitutes both mind and matter. My evaluation will demonstrate that James’s and Russell's supposedly neutral entities are not neutral as their exponents claim because they fail to satisfy important criteria set for a theory to be genuinely neutral. There are two fundamental elements within my (...) discussion of the neutral entities. Firstly, I shall demonstrate that although James's initial repudiation of dualistic epistemology of subject and object, knower and known, led him to avoid metaphysical dualism of mental and physical, in Cartesian sense, by committing him to the view that there is one kind of entity called "experience", his final analysis admitted an internal distinction within the supposedly simple neutral entities. I shall call this covert dualism. Accepting James’s radical empiricism as an archetype, Russell’s early commitment to neutral monism led him to assert three distinctive kinds of entities, sensation, image and unperceived, and was therefore not complete as that of James. In order to bring his theory in line with James, Russell, in his mature version, entirely repudiated the dualistic view of perception which, following Moore, he accepted, to reject idealism. Russell declared percept as the neutral entity, which is both mental and material at once. But by re-introducing epistemological dualism, as James did, Russell admitted that a percept is not simple but complete bundle of compresent qualities and relations. 1 shall argue that like James’ his theory also collapses into covert dualism. Secondly, I shall argue that to produce a genuinely explanatory theory of neutral entities James and Russell exploited science to justify their theories. In course of their analysis they produced various arguments which has been considered as circular. An attempt will be made to show that the apparent circularity of their analysis is really part of a sophisticated programme, now known as bootstrapping. The notion of a bootstrap strategy has recently been developed in philosophy of science, and suggests a way in which the same evidence can be used to generate both a general and specific hypothesis. The thesis is divided into eight chapters. Chapters one, two and four are largely exegetical and chronological, and discuss the development of neutral monism especially in James and Russell’s philosophy together with the general characteristics of the theory as distinguished from other theories explaining mind and matter. Chapters three, five and six critically analyse James’s and Russell’s versions respectively to show their theories collapse into covert dualism. In chapter seven we argue that the alleged circularities in their theory are non- viscious and their employment of a bootstrap strategy introduced a profound innovation in epistemology. (shrink)
