On Comparative History

Abstract

When John Stuart Mill composed his System of Logic, he maintained that valid application of the comparative method to problems in the moral or social sciences is impossible, or, at best, inadmissible, since it must be based on a priori judgments. Mill founded his objection to the use of this method in social science on two essentially interrelated propositions: the uniqueness of each social event, and the multiplicity and variety of causal factors which may be considered as having a determining influence on these events. Although this conception of the special nature of social events has, on the whole, remained unchanged, social scientists have freely applied the comparative method to the analysis of social problems. History has been outstanding among the social sciences in rejecting longest the application of this method. The main argument against its use was derived from the description of history formulated by Ranke and his school, a description which was endowed with a philosophical underpinning by Windelband and Rickert, who classified sciences according to method into a nomothetic and an ideographic group. History was the ideographic science par excellence, and with the strong historical emphasis that was placed in Germany upon other social sciences as well, there was a tendency to return to the viewpoint of Mill and to regard as scientifically suspect generalizations in social science based on the application of the comparative method.
