JOHN BATES CLARK AS AN ECONOMIST Jacob H. Hollander THE appraisal of scientific place is never easy. In politics and in affairs there is definite service that can be evaluated in relation to positive phenomena. Not so with stuff of the mind. Ordered knowledge grows by assembly, with, at best, “a master builder” from time to time giving new direction or changed emphasis. The years lend perspective and engender piety, and the historian of thought perforce ventures judgments. But of the living there is likely to be either adulation or hypercriticism. This is why we have no real history of political economy but only surveys of economic doctrines. No one has set forth with finality the contributions of Ricardo or of Malthus or of John Stuart Mill. Even one hundred and fifty years after, the com- memorative addresses lately given in this country and abroad present widely different estimates of the achievement of Adam Smith. Sometimes a gifted student has surveyed the life and work of his teacher and been able to salvage objectivity from gratitude and affection. But the gift is not common. If English- speaking economists have been remiss in estimating their living great, it is because of the intricacy of the task rather than of the grudge of indifference. The real work of John B. Clark as an economist lies within the thirteen years from 1886 to 1899. There were earlier path-finding papers in The New Englander, and a rich bibliography attests the mental vigor of later years. But The Philosophy of Wealth first presented in something approaching systematic form Clark’s basic ideas, and with The Distribution of Wealth the exposi- tion of his philosophy in all but its related phases and its specific applications may be regarded as complete. These thirteen years make up an important epoch in the development of American economic thought. The association
