“A miracle is a violation of the laws of nature; and as a firm and unalterable experience has established these laws, the proof against a miracle, from the very nature of the fact, is as entire as any argument from experience can possibly be imagined.” David Hume, An Enquiry Concerning Human Understanding
“Now, I know this issue is very controversial. But unless and until it can be proven that an unborn child is not a living human being, can we justify assuming without proof that it isn't? No one has yet offered such proof; indeed, all the evidence...” Ronald Reagan, State of the Union Address
“It is one thing to know that a man is guilty, it is quite another matter to prove him so.” Agatha Christie, The Mysterious Affair at Styles
“If you were asked to prove that two and two made four, you might find some difficulty, and yet you are quite sure of the fact.” Arthur Conan Doyle, A Study in Scarlet
“Any physical theory is always provisional, in the sense that it is only a hypothesis: you can never prove it. No matter how many times the results of experiments agree with some theory, you can never be sure that the next time the result will not...” Stephen Hawking, A Brief History of Time
“You can prove anything you want by coldly logical reason—if you pick the proper postulates.” Isaac Asimov, I, Robot
“You can hire logic, in the shape of a lawyer, to prove anything that you want to prove.” Oliver Wendell Holmes Sr., The Autocrat of the Breakfast-Table
