ABSTRACT
ACCORDING to its title this book is an introduction to moral philosophy. But it must be admitted straight away that as a title this is neither novel, inspiring nor informative. So before doing anything else I had better try and give some more exact indication of what kind of book it is intended to be. This should provide at least some sort of warning for those who very wisely prefer to read the first chapter of a book in the shop before deciding (usually) not to buy it after all.
