Although what constitutes justice may vary depending on culture or historical context, all forms of justice are built on a foundation of moral assumptions that include ideas about ethics, fairness and the law. Philosophers have often debated the nature of both morality and justice and their relationship with each other and in this collection we explore some of the most influential ideas on the topics from Kant to Bentham and investigate problems such as can inequalities be justified, provided they are to the benefit of the worst off? This material forms part of The Open University course A222 Exploring philosophy.
