The third edition includes a more extensive treatment of ethics and religion (Chapter 2), which provides the framework for a moral dialogue that reaches across sectarian divides. It also contains a revised final chapter on the continuously unfolding nature of ethical understanding and an expanded appendix that gives detailed advice on writing various types of ethics papers. Ideal for introductory courses in ethics and applied ethics, A Practical Companion to Ethics, Third Edition, can also be used in any course related to critical thinking.
