John Wesley Powell,
Truth and Error — Chapter XVIII.
(1898)
“ A man may bear his own letter to his friend and by a figure of speech may be said to be his own mediator. But when you forget the figure of speech and call the man a mediator who acts upon another you have used the word illegitimately, and when you go still further to speak of the action of a person upon himself as mediation, you have reduced the term to an absurdity. ”
