Etymology: Aristotle gave this word its philosophical life. In Greek, "akrasia" described a person who knows the better course but acts against it, a state he worked through in the "Nicomachean Ethics." The word grows from "akratēs," meaning "powerless" or "without authority," built from the prefix "a-" (not) and "kratos," meaning might, strength or dominion. So the root sense is simply a lack of mastery over oneself. The Greek word had a wider range before philosophy narrowed it. "Akratia" could mean debility or impotence in a general sense, and it also covered incontinence and self-indulgence. The philosophical sense of knowing the good yet failing to do it was what gave it the meaning it carries today in English. Its English form is a doublet of "acratia," a related borrowing from the same Greek family, which shows how one ancient word could reach English twice through slightly different routes.
