A seminal figure in European, especially English Catholicism and a critic of the doctrine of papal infallibility that was being promulgated by Pius IX at the time. He was a contemporary of Gladstone, and his influence and learning was spread by Gladstone in the 19th century. We know him today as the coiner of the phrase: Power tends to corrupt; absolute power corrupts absolutely. Great men are almost always bad men.
