One of the first, extremely important classical works of political philosophy is Plato's Republic, which was followed by Aristotle's Politics, both created in the context of Athenian democracy.
Roman political philosophy was influenced by Greek schools of thought, particularly Stoicism, in conjunction with the Roman tradition of republicanism, as evidenced by the political philosophy of the Roman statesman Cicero and later thinkers such as Marcus Aurelius.
His entry in the catalogue of the British Library lists him as such.
However, throughout his career as a philosopher, historian, and essayist, Hume maintained a clear and consistent interest in a whole series of political questions.
The history of political thought has often overlapped with the history of philosophy.
Plato (left) and Aristotle (right) from a detail of The School of Athens, a fresco by Raphael, whose works (Plato's Republic and Aristotle's Politics) secured the two Greek philosophers as two of the most influential political philosophers As an academic discipline, Western political philosophy has its origins in ancient Greek society, when city-states were experimenting with various forms of political organization including monarchy, tyranny, aristocracy, oligarchy, and democracy.Independently, Confucius, Mencius, Mozi and the Legalist school in China, and the Laws of Manu and Chanakya in India, all sought to find means of restoring political unity and political stability; in the case of the former three through the cultivation of virtue, in the last by imposition of discipline.In India, Chanakya, in his Arthashastra, developed a viewpoint similar to Chinese Legalists, and foreshadowed the ideas of Niccolò Machiavelli.Ancient Chinese and Indian civilizations resembled Greek civilization in that there was a unified culture divided into rival states.In the case of China, philosophers found themselves obliged to confront social and political breakdown, and seek solutions to the crisis that confronted their entire civilization.Hume 2000 (cited under A Treatise of Human Nature), Hume 1998, and Hume 1999 (both cited under An Enquiry Concerning Human Understanding and An Enquiry Concerning the Principles of Morals) did not entirely displace the Selby-Bigge and Nidditch editions but took their place alongside them as standard editions of these texts.In the secondary literature, you will regularly see both sets of editions cited.Until the late 1990s, the standard editions of A Treatise of Human Nature, An Enquiry Concerning Human Understanding, and An Enquiry Concerning the Principles of Morals were Hume 1978 (cited under A Treatise of Human Nature) and Hume 1975 (cited under An Enquiry Concerning Human Understanding and An Enquiry Concerning the Principles of Morals), commonly referred to as the Selbe-Bigge and Nidditch editions.Between 19, Oxford University Press released new student editions of the Treatise and the Enquiries.In the Age of Enlightenment, political entities expanded from basic systems of self-governance and monarchy to the complex democratic and communist systems that exist of the Industrialized and the Modern Era.In parallel, political systems have expanded from vaguely defined frontier-type boundaries, to the definite boundaries existing today.
