Abstract
The article uses the constructivist perspective and some approaches from the area of new institutionalisms in order to reason over the possibilities and limits of the study of welfare state. On the example of welfare state it at the same time analyses the research possibilities of certain forms of interconnecting social sciences and politics.
The authors claim that social sciences rather construct than discover its subject (welfare state in our case) and this happens not only by the way of grasping the world around us through cognitive and normative frames, that is, through language, but also through expert counseling to political actors, who understand science in general as a cognitive authority and who for various reasons take over cognitive frames science produces. It is paradoxical that although political actors do not share the constructivist perspective, they - by their willingness and interest in taking over these cognitive frames - strengthen the constructivist nature of social sciences.
