Political philosophy

sub-discipline of philosophy and political science

Political philosophy is the study of politics, liberty, justice, property, and rights. Also the law, and its enforcement (a legal code) by authority. It concerns not the details, but the basic principles, reasons and arguments.

Plato (left) and Aristotle (right), from a detail of The School of Athens, a fresco by Raphael.
Plato's Republic and Aristotle's Politics were influential works

Topics studied include the purpose of government, what rights and freedoms it should protect, what form it should take, and what the law is. Also, what duties citizens owe to a legitimate government, and when it may be legitimately overthrown, if ever.

Political philosophy is a philosophical back-up to political science, which is the social science study of politics.
