"Economics and the Idea of Natural Law," _Quarterly Journal of Economics_, XLIV, 1-39 (Nov., 1929). ("The evolution of the idea of 'law' in economics" paralleling "its evolution in the natural sciences" led to belief in an economic mechanism which "was regarded as a wise device of the Creator for causing individuals, while pursuing only their own interests, to promote the prosperity of society, and for causing the right adjustment to one another of supplies, demands, prices, and incomes, to take place automatically, in consequence of the free action of all individuals." The author suggests that there is evident an incongruous dichotomy between the mechanistic idea of the physiocrats and their assumption that enlightened men "would be able to use government as a scientific tool for carrying out purely rationalistic measures in the common interest."
