Abstract

In this dissertation I uncover a logic of the development of atomism in early Greek philosophy that has not been previously recognized in the philosophical literature. This logic results from the nature of subjectivity and the attempt by reflective subjects to understand the world in which they live. Thus because of the nature of illusions built in to perception and reflection, reflective subjects who attempt to understand their world will develop more or less accurate accounts according to their ability to see through these illusions. ;Physicalism, as it is understood by Professor Phillip Scribner of The American University and explained in currently unpublished manuscripts, provides the interpretative key that reveals the underlying logic in the development of early Greek philosophy. It is therefore necessary to explain this particular form of physicalism in some detail in order to understand the terminology and categories to be used in the historical analysis. To this end I explain the physicalist ontology and philosophy of science, the genesis of the problem of mind in Modern and Contemporary philosophy, the physicalist solution to the problem of mind, and the nature of the physicalist critique of the history of philosophy. ;In the historical sections the themes of materialism, reductionism, and realism are used to compare the views of Thales, Anaximander, Anaximenes, Parmenides, Empedocles, Anaxagoras, Leucippus, and Democritus and to show how their various positions on the themes follow from their assumptions about the nature of subjectivity. I argue that the predecessors of atomism were all naive realists and that this assumption about the nature of mind generates the problems of early Greek philosophy. The resolution of these problems follows from the development of critical realism by Leucippus and a form of proto-physicalism by Democritus. ;The main sources used are English translations of Die Fragmente der Vorsokratiker by H. Diels, edited by W. Kranz, and a variety of secondary sources which provide the consensus of modern authorities
