Policy, Sir, is not my principle, and I am not ashamed to say it. There is a principle above everything that is political. And when I reflect on the command that says, ‘Thou shalt do no murder,’ believing the authority to be divine, how can I dare set up any reasonings of my own against it? And, Sir, when we think of eternity, and of the future consequences of all human conduct, what is here in this life which should make any man contradict the principles of his own conscience, the principles of justice, the laws of religion and of God?
—William Wilberforce, speech in the House of Commons, May 12, 1789
