Henry Fielding,
An Enquiry into the Causes of the late Increase of Robbers…
(1751)
“ There is no Branch of the Law more bulky, more full of Confusion and Contradiction, I had almost said of Absurdity, than the Law of Evidence as it now stands.One Rule of this Law is, that no Man interested shall be sworn as a Witness. By this is meant pecuniary Interest; but are Mankind governed by no other Passion than Avarice? Is not Revenge the sweetest Morsel, as a Divine calls it, which the Devil ever dropped into the Mouth of a Sinner? ”
