Read the following passage carefully and answer the questions that follow:
In the fifth century B.C., Plato and Aristotle discussed whether monarchy or democracy was better. In modern times, Rousseau first argued for freedom as a fundamental right of humankind. Karl Marx argued that equality was as crucial as freedom. Mahatma Gandhi discussed the meaning of genuine freedom. Dr. B. R. Ambedkar vigorously argued that the scheduled castes must be considered a minority, and these ideas find their place in the Indian Constitution.
Political theory deals with the ideas and principles that shape Constitutions, governments and social life in a systematic manner. It clarifies the meaning of concepts such as freedom, equality, justice, democracy, secularism and so on. It probes the significance of principles such as rule of law, separation of powers, judicial review, etc. This is done by examining the arguments advanced by different thinkers in defence of these concepts. Though Rousseau or Marx or Gandhi did not become politicians, their ideas influenced generations of politicians everywhere. There are also contemporary thinkers who draw upon them to defend freedom or democracy in our own time. Besides examining arguments, political theorists also reflect upon our current political experiences and point out trends and possibilities for the future.
