This chapter discusses relativism, teleology, and several moral philosophers' theories. It explores the ideas that morals vary by society and time, and that utilitarianism aims to maximize happiness and minimize suffering. The chapter outlines egoism, act-utilitarianism, and rule-utilitarianism as common forms of teleology. It acknowledges arguments for and against relativism and teleology, such as how they promote tolerance but lack objective standards. The chapter concludes with a case study about a principal considering what to say in a reference about a teacher's health and likelihood to remain in a new position long-term.
