?Today we can establish that, in spite of worthy principles about business ethics, we are constantly faced with dubious practices (financial and other) in the corporate world.It is my intention to confront the reader (the student) time and again with questions about the actual economic, social and ecological boundaries of our society. Philosophy is a must - also and especially in today's commercialized society - to rationally obtain an answer to very specific societal issues.In Part 1, Philosophy and ethics, a number of concepts are being clarified. Then we take a closer look at some of the philosophers who have in the course of Western history been important - and still are - to Western business ethics. In Part 2 we move on to business ethics, with an in-depth exploration of Corporate Social Responsibility (CSR) in its many forms, illustrated with a great variety of cases. We learn about three important ethical models in Western business ethics, to then set up a step-by-step plan that enables us to come to a well-considered verdict on an ethical case in the business world.
