A wrong is unredressed when retribution overtakes its redresser. It is equally unredressed when the avenger fails to make himself felt as such to him who has done the wrong.
We avenge intellect when we dupe a fool, and it is a victory not to be despised for a fool is covered with steel and it is often very hard to find his vulnerable part.
