Machiavelli's Place in Western Thought

What is “modern” or “original” in Machiavelli's thought? What is Machiavelli's “place” in the history of Western ideas? The body of literature debating this question, especially in connection with The Prince and Discourses, has grown to truly staggering proportions. John Pocock (1975), for example, has traced the diffusion of Machiavelli's republican thought throughout the so-called Atlantic world and, specifically, into the ideas that guided the framers of the American constitution. Paul Rahe (1992) argues for a similar set of influences, but with an intellectual substance and significance different than Pocock. For Pocock, Machiavelli's republicanism is of a civic humanist variety whose roots are to be found in classical antiquity; for Rahe, Machiavelli's republicanism is entirely novel and modern. Likewise, cases have been made for Machiavelli's political morality, his conception of the state, his religious views, and many other features of his work as the distinctive basis for the originality of his contribution.
Yet few firm conclusions have emerged within scholarship. One plausible explanation for the inability to resolve these issues of "modernity" and "originality" is that Machiavelli was in a sense trapped between innovation and tradition, between via antiqua and via moderna (to adopt the usage of Janet Coleman 1995), in a way that generated internal conceptual tensions within his thought as a whole and even within individual texts. This historical ambiguity permits scholars to make equally convincing cases for contradictory claims about his fundamental stance without appearing to commit egregious violence to his doctrines. This point differs from the accusation made by certain scholars that Machiavelli was fundamentally “inconsistent” (see Skinner 1978). Rather, salient features of the distinctively Machiavellian approach to politics should be credited to an incongruity between historical circumstance and intellectual possibility. What makes Machiavelli a troubling yet stimulating thinker is that, in his attempt to draw different conclusions from the commonplace expectations of his audience, he still incorporated important features of precisely the conventions he was challenging. In spite of his repeated assertion of his own originality (for instance, Machiavelli 1965, 10, 57-58), his careful attention to preexisting traditions meant that he was never fully able to escape his intellectual confines. Thus, Machiavelli ought not really to be classified as either purely an "ancient" or a "modern," but instead deserves to be located in the interstices between the two.
