Abstract

This dissertation argues that the disjunction between philosophical ontology and the commonsense universe in early Greek thinkers results in a concomitant incommensurability of language and the kosmos. When language and the world no longer stand in a relationship of one-to-one correspondence, the two related problems of unwritability and ineffability arise. ;I trace the linguistic consequences of the separation of the sensible and noetic worlds historically, from early Eleatic thinkers through Plato and neoplatonism . I argue that the tendency of modern scholarship to construct philosophy, rhetoric, and poetry as distinct disciplines is not only historically inaccurate when applied to classical thinkers, but also obscures the unified and interdisciplinary character of the Greek inquiry into the nature of language and the world and the relationship between logos and kosmos. I conclude by examining the doxographical tradition to show that the model of Greek thought that I advocate is the one we find in ancient histories of philosophy and rhetoric. ;Although this dissertation concentrates on the relationship between philosophy and rhetoric in antiquity, it does have consequences for contemporary approaches to both disciplines. If philosophy and rhetoric have their origins in a unified science of logos rather than a war between sophists and philosophers, we no longer can justify our Balkanization of the two disciplines on historical grounds. Poetry, philosophy, and rhetoric all are concerned with language and its relationship with the world, and just as it is not particularly advantageous to divide the world into warring nations, so it is equally unproductive to divide the understanding of logos into warring disciplines
