Professor Pompa's study of Vico has done a great deal to stimulate and inform the growing interest in the English-speaking world in this remarkable figure. It remains the only work devoted almost exclusively to an interpretation of the New Science and offers a comprehensive guide to the main theoretical problems to which the text gives rise. For this second edition Professor Pompa has responded to the reactions of reviewers and critics and added a new chapter which analyses Vico's conception of the principles which govern the development of law.
