Called to Happiness ~ Guiding Ethical Principles is a high school textbook designed to guide the student through a study of the voluntary human act so that he can determine for himself those acts which will lead to true human happiness. Using St. Thomas Aquinas as a guide, the text brings college Ethics down to the high school level. The text investigates the purpose of human life, the nature of human action, the determination of good and evil acts, and the role of moral law, conscience, and virtue in achieving human fulfillment. With questions to guide the student and “Cases in Point” to highlight the relevancy of the subject matter, the text is a valuable aid in a person’s lifelong pursuit of genuine happiness.
