Do not open your minds to the filtering of the fallacious doctrine that it is less infamous to murder men for their politics than for their religion or their money, or that the courage to execute the deed is worse than the cowardice to excuse it. Let us not flinch from condemning without respite or remission, not only Marat and Carrier, but also Barnave. Because there may be hanging matter in the lives of illustrious men, of William the Silent and Farnese, of Cromwell and Napoleon, we are not to be turned from justice towards the actions, and still more the thoughts, of those whom we are about to study.
~ John Emerich Edward Dalberg-Acton
