Like most other terms in ethical discourse, this term manners lends itself to various definitions. One of the most helpful comes from an early twentieth-century English jurist John Fletcher Moulton, first baron of Bank and for many years a lord justice of appeal. What he called "manners" we would call "ethics." His phrase for it remains one of the more useful and astute definitions of ethics ever devised: "obedience to the unenforceable."
