Kant's famous question "What should I do?" precisely outlines the field of ethics. Various answers and solution models have been developed in philosophy throughout history. This volume helps to navigate this broad area. The selected texts are organized not chronologically, but by overarching themes into four groups: "Descriptive Ethics," "Metaethics," "Normative Ethics," and "Applied Ethics." In this way, the volume provides orientation in the confusing thicket of opinions and is particularly suitable for school instruction and university use.
