Abstract: This essay reconsiders the meaning of politics. It argues that economics offers theory and language that can contribute to the understanding and fulfillment of political life by facilitating analysis of the public interest. However, economics does not provide an escape from political disagreement, whether based on inevitable differences of interest or of belief, or on self-serving efforts to advance one cause at the expense of another. As a language of discourse, economics is shown to be compatible with a broader conception of human nature than is sometimes claimed by its practitioners or acknowledged by its critics.
