This book is a philosophical introduction to ethics. It differs from existing texts by focusing on a basic philosophical problem about morality, its apparent immunity from observational testing. Other texts either ignore this issue altogether, in order to concentrate on interesting but largely nonphilosophical discussions of moral problems, or treat the issue as only one of several highly technical questions in something called 'meta-ethics.'
