Like a great work of literary art, which indeed it is, Alexis de Tocqueville's extraordinary analysis of American society grows more impressive with each exposure to it. Everything has changed and nothing has changed since Democracy in America was published in the 1830’s. Its author grasped with remarkable perception both the mutable and the immutable qualities of man. There could be nothing more salutary for us today than to assimilate his fine sense of what was permanent in a world which, like ours, was undergoing deep convulsions. Committed to the classical economics of Adam Smith, Tocqueville did not share Smith's illusions about the eternal nature of the market. On the contrary, as Albert Salomon has emphasized, his point of view was Heraclitean, the specter of continual change and ceaseless transformation dominating his thought. Surely such a perspective, which antedates both Darwin and Marx, is more appropriate for sociologists in a revolutionary age than elegantly constructed theories of social equilibrium which treat change as a special problem or a deus ex machina.
