 In addition to the uniqueness of the human sciences, the Austrian School of Economics emphasized the passage of time, the uncertainty inherent in human decision making, and the complexity of the economic order. The complexity aspect is not new to the Viennese economists, but can be seen in Adam Smith’s discussion at the beginning of The Wealth of Nations of the division of labor and the spontaneous far-flung patterns of cooperation required to such mundane things as a worker’s woolen coat. The number of exchanges, Smith states, exceeds all computation. The Austrian School added to this computational complexity the idea of ceaseless change that requires constant adaptation and adjustment to the shift in circumstances, including changes in tastes, technology and resource availability. The understanding of the price theory and the market system from the early development by Menger and Bohm-Bawerk, and the more mature formulation in Mises and Hayek argued that a proper understanding of the market economy did not strive to depict the efficiency properties of the end-state, but the adaptive and learning aspects of the system.
