Abstract

In this dissertation, I provide the logical foundation for a solution to the mind-body problem, a solution which is directly based upon Wilfrid Sellars' analogical theory of thought and sensation. Chapters I-IV are devoted to an interpretation, analysis, and constructive criticism of Sellars' notions of the inner thought episode and the sensing state. My analysis is offered in support of three general contentions: I argue that the postulation of inner thought episodes and sensing states is necessary for adequate explanations of agent behavior; I hope to show how the analogical theory of inner thought episodes and sensing states actually generates a legitimate problem concerning the relationship between the mental and the physical; and I demonstrate the importance of the notion of analogy in philosophical theory construction. I suggest that the role of analogy provides the key for the solution to the mind-body problem. ;Chapter One is essentially introductory in nature. I offer an interpretation and reconstruction of Sellars' illustrative story entitled "The Jonesean Myth" . The "Myth" provides a suitable representation of Sellars' overall philosophy of mind. But perhaps more importantly, the "Myth" is a paradigm example of what I shall call the analogical method of inquiry, a method employed for the introduction of the notions of inner thought episodes and sensing states. In brief, I want to show how the "Myth" provides the logical basis for a theory adequate for explanations of the mental activity of agents. ;Chapters II and III are closely related. In Chapter II, I present a theory of linguistic representation which will serve as the analogical base for the introduction and characterization of the inner thought episode. In Chapter III, I develop the notion of the inner thought episode , and I examine its nature and status as a theoretical construct. Chapters II and III are thus related by the Sellarsian thesis that the concept of mental representation is to be understood in terms which apply, primarily, to characterizations of the features of the linguistic framework presented in Chapter II. ;In Chapter IV, I argue, again following Sellars' lead, that the explication of the notion of the perceptual thought episode requires the introduction of a second distinct sort of inner episode, namely, that of the sense experience or sensing state. The argument offered in Chapter IV is designed to show that sensing states are theoretical constructs, the reference to which is essential for explanations concerning the occurrence and nature of perceptual representations. Sensing states are introduced and characterized by an analogical extension of families of predicates which are suitable for the identification and description of ordinary physical objects . ;In Chapter V, I propose a solution to the mind-body problem, as the latter is generated by the analysis given to the thought episode and the sensing state . In general terms, I argue that any purported solution to the mind-body problem must provide an explanatory basis for agent behavior, and it is for this reason that I reject "reductionistic" theories of mind of the kind represented by logical behaviorism, type-identity physicalism, and Turing Machine functionalism. My solution, instead, involves a commitment to what I shall call token physicalism, a thesis which is contingent upon the development of a theory of neurophysiology which is rich enough to capture, in an analogical sense, both the intentional features of the thought episode, and the occurrent-like qualities which are exemplified by the sensing state
