Since the mid-1960s, the application of ethical theory to moral, social, political, and legal issues has formed a growing part of public life and of the philosophical curriculum. Except perhaps during the 1950s and the flowering of ordinary language philosophy, moral philosophers have always to some extent been concerned with the practical application of their theories. On the whole, however, they did little more than sketch implications or draw provisional conclusions with regard to practical issues based upon some distant familiarity with a few empirical facts. Today, the opposite is the case: they have come to immerse themselves in the subject matter of the issues with which they are normatively concerned, whether these come from law, medicine, business, or the affairs of social and political life. As a result, they have come to apply their theories in a much broader and deeper understanding of the factual setting within which the issues in question arise and have become of public concern.

Courses in applied ethics now figure throughout the philosophical curriculum, including, increasingly, within philosophy components of professional education. More and more periodicals – philosophical, professional, popular – devote space to medical and business ethics, to environmental and animal rights issues, to discussions of suicide, euthanasia, and physician-assisted suicide, to surrogate motherhood and the rights of children, to the ethics of war and the moral case for and against assisting famine victims, and so on.
