There is a story about the connection between the rise of consent theories of political obligation and the fall of natural law theories of political obligation that is popular among political philosophers but nevertheless false. The story is, to put it crudely, that the rise of consent theory in the modern period coincided with, and came as a result of, the fall of the natural law theory that dominated during the medieval period. Neat though it is, the story errs doubly, (...) for it supposes both that consent did not play a key role in natural law theories of political authority offered in the medieval period (a supposition falsified by close inspection of the view of Aquinas, perhaps the paradigmatic natural law theorist) and that natural law theory did not play a key role in the consent theories of political authority offered in the modern period (a supposition falsified by close inspection of the views of Hobbes and Locke, perhaps the paradigmatic consent theorists).Footnotes* I owe thanks to Pat Káin, Paul Weithman, Bob Roberts, and Henry Richardson for instructive criticisms. John Hare was particularly helpful both in criticism and in conversation. I was supported by a fellowship from the Erasmus Institute while this essay was drafted. (shrink)

Philosophy, despite its typical attitude of detachment and abstraction, has for most of its long history been engaged with the practical and mundane-seeming question of whether there is a duty to obey the law. As Matthew Kramer has recently summarized: “For centuries, political and legal theorists have pondered whether each person is under a general obligation of obedience to the legal norms of the society wherein he or she lives. The obligation at issue in those theorists' discussions is usually taken (...) to be prima-facie, comprehensively applicable, universally borne, and content-independent.” This essay is a commentary on the current state of discussion of this perennial philosophical topic.
