In this dissertation I develop a structural model of phenomenal consciousness that integrates contemporary experimental and theoretical work in philosophy and cognitive science. I argue that phenomenology must be “naturalized” and that it should be acknowledged as a major component of empirical research. I use this model to describe important phenomenal structures, and I then employ it to provide a detailed explication of tip-of-tongue phenomena. The primary aim of “structural phenomenology” is the creation of a general framework within which descriptions (...) of experiences may be organized. The work of Husserl, Gurwitsch, the Gestalt psychologists, and many contemporary philosophers and cognitive scientists reveals several basic parameters underlying subjectivity. Chapter I argues that Husserlian methodology possesses problems both of praxis and of internal logic, and that its phenomenological descriptions cannot have the certainty he claimed. Consequently, an adequate phenomenology must incorporate empirical studies. This conclusion enables explicit transitions between empirical investigations and phenomenological insights. Chapter II introduces the theoretical framework underlying my model. I identify four parameters applicable to all experiences: 1) the degree of volitional emphasis with which something is experienced, i.e., the intensity of our focus on it, 2) the degree of non-volitional emphasis, i.e., the degree to which it is salient, 3) a variant of intentionality I term “directionality”, and 4) the property of recursion. Experiences are embedded within a complex set of relationships that unify and direct a layered phenomenal structure. I support these claims with evidence discovered over the past two centuries of research. Chapter III applies my model to the tip-of-tongue (TOT) state, in which difficulty remembering is accompanied by a sense of active searching. I show that a phenomenological description of the TOT experience is dependent on cognitive data, and that a phenomenological analysis is necessary to properly interpret these data. By showing how structural phenomenology offers a perspective from which to elucidate the results of experimental studies, I hope to clarify and establish the explicit role of introspection in empiricism, and of empiricism in phenomenology.

Whether human thinking can be formalized and whether machines can think in a human sense are questions that have been addressed by both Peirce and Searle. Peirce came to roughly the same conclusion as Searle, that the digital computer would not be able to perform human thinking or possess human understanding. However, his rationale and Searle's differ on several important points. Searle approaches the problem from the standpoint of traditional analytic philosophy, where the strict separation of syntax and semantics renders (...) understanding impossible for a purely syntactical device. Peirce disagreed with that analysis, but argued that the computer would only be able to achieve algorithmic thinking, which he considered the simplest type. Although their approaches were radically dissimilar, their conclusions were not. I will compare and analyze the arguments of both Peirce and Searle on this issue, and outline some implications of their conclusions for the field of Artificial Intelligence. (shrink)

All our conscious experiences, linguistic and nonlinguistic, are bound up with and dependent on a background that is vague, unexpressed, and sometimes unconscious. The combination of William JamesÕs concept of "fringes" coupled with Aaron GurwitschÕs analysis of the field of consciousness provides a general structure in which to embed phenomenal descriptions, enabling fringe phenomena to be understood, in part, relative to other experiences. I will argue, drawing on examples from Drew LederÕs book, The Absent Body, that specific and detailed phenomena (...) can and should be interrelated through JamesÕs and GurwitschÕs analyses. I am proposing first that phenomenological descriptions in general could benefit from explicit consideration of the context of the phenomena within the totality of the field of consciousness, and second, that establishing that context requires a general structural model of that field, similar to that provided by Gurwitsch.
