And there's Dr. John Arbuthnot, who in his 1714 Treatsie on the Art of Political Lying wrote:
"Detractory or defamatory lies should not be quite opposite to the qualities the person is supposed to have. Thus it will not be found according to the sound rules of pseudology to report of a pious and religious prince that he neglects his devotions and would introduce heresy; but you may report of a merciful Prince that he has pardoned a criminal who did not deserve it. "
