Quotations
It is a terrible thing a Man should be put to Death for a Crime he is not Guilty of; yet so oddly Circumstances may meet in the infinite variety of Accidents, that it is possible it should come to pass, all the Wisdom that Judges, and Conscientiousness that Juries may be possess'd of, notwithstanding.
1723, Bernard Mandeville, An Essay on Charity and Charity Schools
