That all human beings are one another's moral equals is taken by many to be the fundamental premise of contemporary moral, political and legal theory. It is also the demand of individuals and groups to be treated as equals that drives much of political practice and protest today. However, what does such a claim of 'basic equality' between human beings mean? How can it possibly be true, given that we are unequals in almost every other aspect of our lives? And, who, exactly, is meant to fall within its scope? This volume brings together leading thinkers on basic equality to address these questions. Collectively, they explore the concept of equality in history and criticism, analysing and presenting solutions to the most pressing challenges that have been raised against the principle.
