History of political thought
Overview
Among the many contributions to political philosophy, a continuous thread can be traced from the analytical theorising of the thinkers of Ancient Greece through the writings of the philosophers of The Enlightenment and the teachings of the founders of the French and American revolutions, to the current ideologies of Conservatism, Liberalism, Socialism and their offshoots. Since the contributions of the political philosophers of China and India are not a significant part of that thread, they are conventionally omitted from courses and treatises on the history of economic thought, and given separate treatment elsewhere. Among the topics that are debated throughout what is regarded as the mainstream thread, are the relations between individual and community, and between community and state. Although many issues remained unresolved, an unprecedented degree of ideological convergence began to develop during the latter decades of the 20th century, culminating in a situation that Francis Fukuyama dramatised as "the end of history". However a controversy gathered strength in the 21st century concerning a state's "duty of care" toward its citizens, and the rôle of the international community when an individual state fails to discharge that duty.
