The main objective of this three volumes Encyclopaedic work is to present a historical development and critical analysis of 150 sociological theories from its inception to post-modernity. Sociological theory is a mixture of conceptual efforts, some devoted to developing scientific principles and models, others to describing empirical events, still others dedicated to criticism of oppressive social arrangements, and many directed to meta-analysis of theories and theorists. The idea of bringing out this encyclopaedia of theoretical sociology for the first time is undoubtedly a noble endeavour of the editors which is timely and worth considering. Undoubtedly, this book becomes indispensable source of references for teachers, scholars and readers of sociology.
