Most scholars who write on social contract and classical natural law perceive an irreconcilable tension between them. Social contract theory is widely considered the political-theoretic concomitant of modern philosophy. Against the regnant view, The Social Contract in the Ruins, argues that all attempts to ground political authority and obligation in agreement alone are logically self-defeating. Political authority and obligation require an antecedent moral ground. But this moral ground cannot be constructed by human agreement or created by sheer will—human or divine. All accounts of morality as constructed or made collapse into self-referential incoherence. Only an uncreated, real good can coherently ground political authority and obligation or the proposition that rightful government depends on the consent of the governed. Government by consent requires classical natural law for its very coherence.
