EXCEPTION
—n.
A thing which takes the liberty to differ from other
things of its class, as an honest man, a truthful woman, etc. "The
exception proves the rule" is an expression constantly upon the lips
of the ignorant, who parrot it from one another with never a thought
of its absurdity. In the Latin, Exceptio probat regulam means
that the exception tests the rule, puts it to the proof, not
confirms it. The malefactor who drew the meaning from this
excellent dictum and substituted a contrary one of his own exerted an
evil power which appears to be immortal.
