Abstract
It has been repeatedly maintained that the selection mechanism is mainly “subjective selection” in the social evolution as against “natural selection” in the biological evolution. But this claim derives from the misconceptualization of the mechanism of social evolution. Theoretical entities that are selected are “individuals” as physical entities in the biological evolution as against “subjects” as ideal entities in the social evolution. Because of the confused identification of both entities, the logic of biological reductionism and the above claim are deduced. Based on the proper conceptualization, it is supposed that on the basis of subjects' worlds (knowledges, beliefs)the natural selection is the selection mechanism effects on the rules of subjects and the subjective selection is the selection mechanism effects on the actions of subjects. Therefore the logic of the explanation for the contains of subjects' worlds is indispensable so that the observer can discriminate between the natural selection and the subjective selection in the actual process of social evolution.
