Political science is a social science chiefly interested in collectivities, e.g., the state, and can be seen to differ from other social sciences by its focus on power. Following Eric Voegelin , legitimation is sought by Schutz in transcendent realities and there are also central myths, symbols, and forms of representation. Familiar basic concepts are mentioned. Empirical data in this science are collected through interviews, participatory observation, and questionnaires and historical knowledge is plainly relevant. Collective course-of-action types are at least central and as such also distinctive for political science.
