This addition to the St Andrews Studies series contains a wide-ranging collection of essays on all aspects of moral philosophy and its impact upon public life in the twenty-first century. The book brings together ethicists from a variety of traditions interested in moral truth and its relation to religious faith. A key theme is interaction between major Catholic thinkers with philosophers from non-religious traditions. Topics include reason and religion, natural law, God and morality, anti-consequentialism, rights and virtues.
