Over the years the philosophical landscape has changed somewhat, and in this second edition Arthur Holmes adjusts the argument and information throughout, completely rewriting the original chapter on virtue ethics and adding a new chapter on the moral agent. Holmes addresses the questions: What is good? What is right? How can we know? In doing so he also surveys a variety of approaches to ethics, including cultural relativism, emotivism, ethical egoism and utilitarianism all with an acknowledgment of the new postmodern environment."
