Before ethics became a university subject, êthos (ἦθος) could mean something as ordinary as a settled habit or customary way of life. Aristotle turned that everyday word into philosophical equipment, most famously in Ta Ethika, his works on how human beings ought to live. Centuries later, English borrowed the idea through Late Latin ethica, Middle French ethique, and Middle English etik, eventually preserving the plural form as “ethics.” The same Greek family produced ethos, now used for the characteristic spirit of a people, an age, or even a company—and it sits beside words such as ethicist and eugenics, the latter coined by Francis Galton in 1883 on the model of “ethics.” So ethics is not originally a list of commandments; it is the accumulated character of a life, inspected under a philosopher’s lamp.
