It is natural for us to wonder what should I do, and why? And although a combination of common sense and upbringing aids us in answering our questions, it is also natural for us to seek answers that are grounded in something deeper and more enduring than our personal dispositions and those of our parents. We seek a genuinely good life and the practical wisdom necessary to arrive at happiness. In this Introduction to Ethics, Brian Besong presents a comprehensive and contemporary introduction to the practical wisdom handed down to us by Aristotle, St. Thomas Aquinas, and many others--a position now commonly called "natural law." Written as a beginner's guide, the book systematically explores a range of moral issues including moral knowledge, happiness, right and wrong action, and virtues, to name a few. Introduction to Ethics explains in a lively way how natural law provides principled and persuasive answers to our most fundamental moral questions.
