As one of the most important ethicists to emerge since the Second World War, Alan Gewirth continues to influence philosophical debates concerning morality.In this ground-breaking book, Gewirth’s neo-Kantianism, and the communitarian problems discussed, form a dialogue on the foundation of moral theory.Themes of agent-centered constraints, the formal structure of theories, and the relationship between freedom and duty are examined along with such new perspectives as feminism, the Stoics, and Sartre.Gewirth offers a picture of the philosopher’s theory and its applications, providing a richer, more complete critical assessement than any which has occurred to date.
