Abstract

This dissertation argues that the current tendency to define liberal constitutionalism in terms of the impersonal and formalistic ideals of the rule of law diverges from early liberal theories of constitutionalism, which were sensitive to the occasional need for extra-legal discretionary exercises of power to deal with the unpredictable contingencies of politics. This understanding of politics shaped the constitutional and political thought of liberal thinkers from John Locke, David Hume, and William Blackstone to Alexander Hamilton, James Madison, and other Federalists who defended the extraordinary powers of the American presidency. Since these early liberals recognized that it would sometimes be necessary for an executive to perform extraordinary actions in response to unforeseeable events, they were reluctant to place excessive legal checks on executive power. Consequently, they emphasized the importance of limiting executive power to those with "fit characters." In particular, they looked to those politico-moral virtues associated with republicanism to supplement and enhance the constitutional machinery of government that was designed with the ordinary course of politics in mind. Although early liberal theorists and the designers of the American Constitution abandoned many of the core principles of republicanism, particularly its reliance on a virtuous and active citizenry as the best guarantee of free government, they preserved a place for distinctively republican virtues such as patriotism and disinterestedness in the office of the executive. In fact, the Federalists made the American presidency the primary repository of republican virtue in the new government. The first century of liberal constitutional theorists was actually skeptical of the ability of impersonal institutional devices such as the separation of powers and checks and balances to secure a free and effective government without the presence of fit characters. Since formal institutions are imperfect and often inadequate---both in dealing with political contingencies and in checking the executive---these thinkers supplemented legal and institutional safeguards with character requirements to minimize potential abuses of largely indeterminate executive powers irreducible to law. An abiding conviction that uncertainty is the only certainty in politics led them to prefer flexible approaches rather than the rigid formulas in theorizing constitutionalism
