No sane person wants to lie. Aside from whatever harm lying might cause, lying also chips away at a person’s dignity. Knowing that your words will quickly mold to a model other than Truth somehow cheapens you — as if any model will do. Expediency, authority, greed . . . it’s hard to think of circumstances under which lying about non-private matters doesn’t cheapen a person. Put person X under these conditions, and he’ll say whatever you want him to say. How’s that for a human being? Nothing exalts more than knowing that your words will serve Truth and only Truth.
