All Brands of Historicism Emphatically Reject Economics

All brands of historicism—the German and the British historical schools of the social sciences, American institutionalism, the adepts of Sismondi, Le Play, and Veblen, and many kindred "unorthodox" sects—emphatically reject economics.

The historicists do not eliminate economic reasoning from their treatises. While rejecting an economic doctrine they do not like, they resort in dealing with events to fallacious doctrines long since refuted by the economists.
