"This is a comprehensive and non-technical introduction to ethics. It explores how we find true or reasonable moral principles, applicable to practical cases. In the book the student is presented with seven radically different basic moral theories. Each theory attempts to provide an ultimate answer to the question what ought to be done - and why. Each theory is carefully described, put into historical perspective and critically assessed." The book is intended for undergraduate students of philosophy but it should also appeal to any general reader who is prepared to ask probing and challenging questions in the search for a consistent moral outlook.
