With the Commission on Higher Education’s inclusion of the subject Ethics in the General Education Core Courses in the new curriculum, several textbooks were published by different authors from different universities in the Philippines. All published books tried to provide a guide on how tertiary students can understand Ethics. As part of the authors’ attempt to bring down the level of philosophy to those who are not philosophy major students, they tried their best to provide a definition of ethics and a survey of different ethical systems. Simply put, the published textbooks discussed what ethics is. Ethics is a branch of philosophy that deals with understanding what is right from wrong. Unlike the other branches of philosophy, ethics can be considered as one of the closest philosophical schools to us since it deals with the human person and one’s actions. By looking at this perspective, one can see that it will deal with one’s decisions in particular situations and experiences. Moreover, ethics helps one seek the answers to the questions on what good is, what right is, and how to live a well-lived life. The said questions were tackled by Jove Jim Aguas in his book The Good and Happy Life: An Introduction to Ethical Systems and Theories.
