AbstractThe essay examines medical metaphors in the discourse on government from a cross-cultural perspective. Drawing on George Lakoff and Mark Johnson's theory of metaphor, a comparison of medical metaphors in the political writings in late medieval Europe (c. 1250–c. 1450) and Tokugawa Japan (1602–1867) demonstrates that the European notion of medical treatment as the eradication of the causes of diseases magnified the coercive and punitive aspects of government, while the Japanese notion of medical treatment as the art of daily healthcare served to accentuate the government's role of preventing conflicts and maintaining stability. These differing images of medical treatment metaphorically structured contrasting conceptions of government in the two historical worlds.
