The Republic, a pioneering work of political philosophy, is a dialogue that does not feature Plato directly as at the heart is Socrates - his teacher. Even though the conversations between Socrates and Athenians as well as foreigners take place thousands of years ago, the questions Plato addresses in the volume are far from archaic.

Should men and women have equal rights? Should rulers be responsible for the well-being of their citizens and the healthcare system in general? Is it ever acceptable to lie, especially if it is a so-called 'noble lie'? And of course, how far can we stretch social mobility?

Although many of Plato's ideas are utopian and will be regarded as immensely positive aspirations by contemporary society, some conclusions drawn by the thinker might arouse our questioning or even disdain. In particular, Plato argues that censorship can underpin the citizens' goodness and orderly life of the whole community - an affirmation that is unlikely to be embraced by modern-day democracies.
