Metatheoretical codifications of the sociological writings of George H. Mead, Jose Ortega y Gasset, and Alfred Schutz highlight the importance of the idea of life and of a commitment to a realist perspective. The authors turn common concern with the life concept in three directions: evolutionary emergence, historical rationality, and phenomenological analysis. In spite of differences, these directions share an empirically grounded starting point in the situated individual and its environment, and end with suggestions for a universalist rationality. Preliminary metatheoretical (...) principles from these authors offer a start toward a vital realist sociology fitted to the universal conditions of social life. (shrink)
