John Rex's main mistake

Abstract

Science progresses by the discovery and correction of mistakes in the interpretation of data. John Rex sought ‘to distinguish among the various studies made by sociologists those which are distinguishable as race relations studies’. He examined them from the standpoint of classical sociological theory. His main mistake was his continued but unsuccessful attempt to synthesize two quite different kinds of sociological knowledge. He underestimated the importance of differences in the criteria for the validation of causal explanation and for the projection of historical trends.
