John C. Calhoun's Disquisition on Government is that rarity in American political thought-a work that explicitly declares itself a theoretical study of politics. By purporting to give a comprehensive and systematic account, by claiming to have explored new territory beyond the range of American discoveries, Calhoun in effect put his Disquisition in a class of which it is almost the sole example: an American political theory. But this claim to esteem and originality has been disputed; and in the subsequent debates among his interpreters, we have yet to find a satisfactory solution to the problem that Calhoun represented in such clear shape. Those who have rated him as a statesman and thinker—be that assessment high or low—and those who have accepted or denied his claim to originality have all failed to solve the peculiar problem of how to study and interpret the writing of a man of theory-and-practice. Until that problem is met, our understanding of the Disquisition is not clear and we remain without a way of evaluating Calhoun's merits and originality.
How, then, ought Calhoun's Disquisition, or his high theoretical pretensions in general, best to be understood? Reducing his theory to practice, or saying in effect that the Disquisition was only another string to his pro-slavery bow, forecloses the question of what Calhoun can teach us. Reducing his practice to theory places what is almost a superhuman burden upon a man who was at or near the center of the national political stage for forty tumultuous years. A more moderate procedure would seem to be indicated.
