"This book, which inaugurates the Princeton Monographs in Philosophy series, starts from Plato's analogy in the Republic between conflict in the soul and conflict in the city. Plato's solution required reason to impose agreement and harmony on the warring passions, and this search for harmony and agreement constitutes the main tradition in political philosophy up to and including contemporary liberal theory. Hampshire undermines this tradition by developing a distinction between justice in procedures, which demands that both sides in a conflict should be heard, and justice in matters of substance, which will always be disputed. Rationality in private thinking consists in adversary reasoning, and so it does in public affairs. Moral conflict is eternal, and institutionalized argument is its only universally acceptable restraint and the only alternative to tyranny."--BOOK JACKET.
