Moral problems are unique to humans, and moral awareness is a fundamental aspect of the human experience. Yet questions continue about whether morals are innate or acquired, and whether moral laws are human or divine. Are some actions inherently right or wrong—or must we always consider circumstances, results, and intentions? Here we review history's best moral thinking about our highest ideals about virtue, duty, and the greatest good for the greatest number.

The Morality in Our Age series examines the historical and philosophical background of today's most pressing moral challenges. Here the realities of money, sex, power, and violence meet the ideals of responsibility, integrity, and moral well-being. Though a final "answer" is notoriously elusive in moral discussion, you'll develop a much better insight into the forces and principles at play on today's most serious moral issues, problems, and dilemmas.
