Conditional sentences are only one type of sentence that can be used in the assertion of a theory.
Further, a theory may be set out using only definitions or by combining any of the above into an argument. Secondly, Prof. Kemper, most likely because of his undergraduate education in English rather than sociology, seems to have missed the undergraduate exposure one obtains as a sociology major. He seems not to appreciate the important and interesting theoretical and empirical contributions of Max Weber, Durkheim, Veblen, Michels, Marx, Sumner, Malinowski, Parsons, Etzioni, Blau, G.H. Mead, Pareto, Spemcer, Lester Ward, Georg Simmell, Park and the members of the Chicago School, and so many others. Without a sound understanding of the history of sociological theory and research in behalf of theory, and without a sound understanding of the canons of the different sociological perspectives, one easily suffers from his laments. But if one grasps the dynamic history of sociological thought and the points of conflict among the competing paradigms, he finds sociology not only a science, but a dynamic one.
