Taking the dichotomy of structuralism versus functionalism in nineteenth century biology as the central subject of my study, I explore a network of unquestioned premises and isolate areas where empirical research programs and underlying metaphysical commitments both inform and hinder each other. ;I begin with the Cuvier-Geoffroy debate of 1830--a debate that clearly articulates the tensions between structuralist and functionalist approaches to organic form. On the side of functionalism, I am led to confront the rich concept of teleological causality. The concept of teleology, frequently taken to be semantically univocal, in fact unfolds into a cluster of related notions. I begin to demarcate significant differences between "intentional," "heuristic," "cosmic," and "organismic" teleology. On the side of structuralism, I set out to unearth the presuppositions of materialist versus idealist conceptions of structure--showing where naturalists have been both liberated and enslaved by their respective metaphysical commitments. With the basic divisions between structuralist and functionalist drawn, I set out to trace the dichotomy through the paradigm shift from fixism to transformism. ;In Darwin's system the structural/functional tensions become synthesized into complementary principles of causality. Here I explore the underlying presuppositional shifts which enabled Darwin to harmonize the previously intractable oppositions. These shifts include: rethinking teleology without "design," rethinking the archetype as real progenitor, and adopting a pluralistic perspective regarding causal mechanisms. ;The relative success of Darwin's appropriation of structuralism and functionalism leads to a discussion of the dichotomous character of the central subject itself. I argue that at the root of the dichotomous characterization of structure and function lies an impoverished understanding of teleology. I then offer "organicist" teleology as a powerful alternative to the French-Anglo tradition of "intentional" teleology. Presupposing the alternative teleology forms a challenge to the way in which French-Anglo naturalists have understood structural and functional relations. Together with Darwin's causal pluralism, a richer notion of teleology provides a different set of metaphysical assumptions and leads to an alternative model for empirical research programs
