1. Political Science is the Study of State and Government.
In the political science we study about the theoretical, structural and behavioural aspects of organisation and forms of state and government. Bluntschli says " political science is a science which is concerned with the state, endeavours to understand and comprehend the state in its essential nature, various forms, manifestations and development." According to Robson ," the purpose of political science is to throw light on political ideas and political actions so that the government of man may be improved". The government is the agency of the state through which the purpose of the state is realised. It is the most lively and integral part of the state. According to Paul Janet "political science is that part of social science which treats of the foundation of state and the principles of the Government”.
