Everything we do should be guided by the principles of our natural reason. But do we know what those are?   In a world where confusion regarding material reality itself abounds, now more than ever before we need a true understanding of human nature and how we should act. TAN Books is pleased to present to those beginning their journey in philosophy this short and succinct primer on the elementary reality upon which all civilization is founded: ethics, or how the human person should act.    Written by the author of the textbook himself, the Ethics Study Guide was designed as a companion guide for the reader of the text that offers prompts and questions to help home in on the key takeaways from each chapter and solidify the student's understanding of the text.    Intended to give the basics on human action--a concept simple to understand generally but difficult  to master--Ethics guides the student through the principles needed in clear thinking to encounter and work through difficulties in an increasingly complex world. Knowing the truth of ethical action and what it means for us will enable us to live as ones truly free.    Ethics is the fourth and final volume in the Foundations of Wisdom series by TAN Books; it is designed to take the student from the foundational principles of rational thinking so as to give him the formation to discover the truth and defend against error.
