The primary purpose of the study of Political Science is to provide understanding of politics and government, which are two of the most important forces in human life and society. Although Political Science does not and cannot teach a man how to govern his country, it can yet provide him with the understanding of politics and government. It deals with them in their varied aspects and processes.
It will inform and enlighten the common man and woman of various aspects and processes of politics and government. More importantly, their knowledge will help a politician in the proper performance of his or her role as a practitioner of politics. Consequently, the study of Political Science will enable the politician to understand and improve the working of the government. Professor Robson writes, “The purpose of political science is to throw light on political action and political ides in order that the government by man may be improved.
Only if those entrusted with responsibility for the subject accept the aim of deliberately attempting to solve the political problems which confront mankind in each country and all the nations collectively can we justify a large expenditure of time, intellectual effort, and money on political science.”
