This text provides an understanding of values and how values impact the way we see the world. It also considers questions of reasoning and how principles guide practice. If one places humanity at the heart of practice, we need to know what it is to exist as a worldly being and what it is to be human. Both practitioners and recipients of practice are human, so the book also presents these two perspectives. It formally provides a framework for ethical reasoning and theories, and discusses applications within the beginning of life, end of life, science, education, and business. Its Appendix is devoted to teaching ethics within a multidisciplinary, interactive classroom.
