Parsons' Theory in his latter half indicates his works about after 1960. They consist mainly of 1. structural-functional analysis and its revised theory, as it were, structural-processual analysis, 2. neo-evolutionism theory, which includes the theory of evolutional universals, evolutional change (differenciation, adaptive-upgrading, inclusion, value-generalization), 3. pattern variables revisited, four functional paradigm which is reconstructed by new framework ; external-internal, instrumental-consummatory, 4. a paradigm of the human condition (Physico-chemical system ; A, human organic system ; G, action system ; I, telic system ; L). Parsons convicted that the four functional paradigm has universal applicability everytime and everywhere. This is a kind of Weltanschauung outside of scientific world. We can find there his theory's limitation. But we believe that value of his achievement in theoretical sociology never diminish.
