“Like the British Constitution, she owes her success in practice to her inconsistencies in principle.”

“Let me never fall into the vulgar mistake of dreaming that I am persecuted whenever I am contradicted.”

“All concord's born of contraries.”

“The well-bred contradict other people. The wise contradict themselves.”

“I believe that truth has only one face: that of a violent contradiction.”
