The present paper deals with Cohen's paradigm and its effect on political sciences. Cohen has criticized opposing views of positivism and empiricism through introducing paradigm as the beliefs and values the members of a scientific society share. On the other hand the theoreticians of political sciences use Cohen's paradigm to refer to the diversity of the studies and the lack of one unique paradigm. So, they have tried to make politics a science. Some has used his ideas to develop a sort of political thinking, i.e. the political theory comes from political crisis. In order to criticize their view instead of dealing with the irregularities of opinions and science, we can say they have paid attention to the social and political realities. In fact, change of normative science is a result of changes in the worlds of society and politics and not the normative science itself.
