“Power tends to corrupt, and absolute power corrupts absolutely,” is the most famous quote by the English Catholic historian Sir John Dalberg-Acton. But what exactly did he mean by it?
That particular quote comes from a letter to Bishop Creighton in which Lord Acton explains that historians should condemn murder, theft, and violence whether committed by an individual, the state, or the Church. Here is the context:
I cannot accept your canon that we are to judge Pope and King unlike other men, with a favourable presumption that they did no wrong. If there is any presumption it is the other way, against the holders of power, increasing as the power increases. Historic responsibility has to make up for the want of legal responsibility. Power tends to corrupt, and absolute power corrupts absolutely. s, even when they exercise influence and not authority, still more when you superadd the tendency or the certainty of corruption by authority. There is no worse heresy than that the office sanctifies the holder of it.
Here are the greatest names coupled with the greatest crimes; you would spare those criminals, for some mysterious reason. I would hang them higher than Haman, for reasons of quite obvious justice, still more, still higher for the sake of historical science.
Lord Acton is saying that rather than excuse “great men” because of the burdens placed upon them by their office or authority, we should judge them even more harshly than we would actions of the common man or woman. It’s ironic that Acton had to tell this to a bishop since the Bible has quite a lot to say about abuse of power. Yet even Christian tend to think that we are immune to the temptations of power and that if we were give more authority we wouldn’t abuse it.
