Man is a social or political creature. There are many aspects of human life – political, economic, cultural, religious, moral, psychological, etc. Many sciences have been developed to study these aspects like – Political Science, Sociology, Economics, History, Ethics, etc. These are related to any one of the aspects of human life, so these are social sciences and related deeply to each other. All these sciences are supposed to be inter – related since ancient times. Political thinkers had questioned the efforts to separate these social sciences and emphasised the inter – relationship of these sciences because all social sciences think that man is a social animal and their aim is to make human life better. This basis of integration unites all the social sciences.
All the subjects of social sciences are profited by knowledge of each other and while studying about various aspects of human life they are mutually interdependent even after maintaining their independent identity. They cannot be separated. Thus, it becomes necessary to study other subjects for significant study of any one subject.
