The Stoic conception of ethics, readers should realize, differs from our modern conception. We think of ethics as the study of moral right and wrong. A modern-day ethicist might wonder, for example, whether abortion is morally permissible, and if so, under what circumstances. Stoic ethics, in contrast, is what is called eudaemonistic ethics, from the Greek eu meaning “good” and daimon meaning “spirit.” It is concerned not with moral right and wrong but with having a “good spirit,” that is, with living a good, happy life or with what is sometimes called moral wisdom.
