This textbook provides a quick yet precise access to the biographies and works of six representative classics of ethics: Plato, Aristotle, Cicero, Thomas Aquinas, Immanuel Kant, and John Stuart Mill. This is achieved through a strict focus on their core statements, which are presented in a well-structured and didactically differentiated manner, allowing for optimal learning, memorization, and practice effects. Since many of the arguments used in applied ethics originate from these classic texts, the presentation aims to help formulate a critically reflected judgment on contentious issues in applied ethics. The goal is to qualify students for their exams, while also guiding current ethics teachers towards their subsequent state examinations.
