This is a print on demand edition of a hard-to-find book. The development of economic thought of the mid-19th century is essentially a history of classical English political economy. The tenets of this school were communicated to the U.S., where the writings of Smith, Malthus, Mill, and Ricardo were adopted by early American political economists. But there was also a strain of political economy in the U.S. at that time that opposed the adoption of the philosophy of classical political economy. This was the nationalistically-oriented American school of economic thought, and the foremost member of this movement was Henry C. Carey.
