"Quinn's writings were always the product of lengthy reflection and great care and precision in argument: they are intellectually packed and elegantly written. And they make distinctive contributions at three different levels of moral philosophy: metaethics, moral theory, and applied ethics....I use most of these essays in my own teaching, and they are standard references for those working in the field. Putting them together would create a book of lasting value, which displayed the range and insight of an outstanding moral philosopher." Thomas Nagel
"In reading Quinn's essays, and especially these later papers, we are, I think, clearly witnessing the development of a major figure." The Philosophical Review
This collection of the most important contributions to moral philosophy and the philosophy of action by a renowned moral philosopher includes the development of his own distinctive moral theory in the discussion of substantial, practical moral issues.
