In this volume the author maintains that sociology must learn to combine the insights of both Durkheim and Marx and that it can only do so on the presuppositional ground that Weber set forth. Alexander maintains that the idealist and materialist traditions must be transformed into analytic dimensions of multidimensional and synthetic theory. This volume focusses on the writing of Talcott Parsons, the only modern thinker who can be considered a true peer of the classical founders, and examines his own profoundly ambivalent attempt to carry out this analytic transformation.
