“An honest religious thinker is like a tightrope walker. He almost looks as though he were walking on nothing but air. His support is the slenderest imaginable. And yet it really is possible to walk on it.”

“Don't think, but look! (PI 66)”

“In the middle of a conversation, someone says to me out of the blue: "I wish you luck." I am astonished; but later I realize that these words connect up with his thoughts about me.And now they do not strike me as meaningless any more.”

“Turing attended Wittgenstein's lectures on the philosophy of mathematics in Cambridge in 1939 and disagreed strongly with a line of argument that Wittgenstein was pursuing which wanted to allow contradictions to exist in mathematical systems. Wittgenstein argues that he can see why people don't like contradictions outside of mathematics but cannot see what harm they do inside mathematics. Turing is exasperated and points out that such contradictions inside mathematics will lead to disasters outside mathematics: bridges will fall down. Only if there are no applications will the consequences of contradictions be innocuous. Turing eventually gave up attending these lectures. His despair is understandable. The inclusion of just one contradiction (like 0 = 1) in an axiomatic system allows any statement about the objects in the system to be proved true (and also proved false). When Bertrand Russel pointed this out in a lecture he was once challenged by a heckler demanding that he show how the questioner could be proved to be the Pope if 2 + 2 = 5. Russel replied immediately that 'if twice 2 is 5, then 4 is 5, subtract 3; then 1 = 2. But you and the Pope are 2; therefore you and the Pope are 1'! A contradictory statement is the ultimate Trojan horse.”

“In the eighteenth century, philosophers considered the whole of human knowledge, including science, to be their field and discussed questions such as: Did the universe have a beginning? However, in the nineteenth and twentieth centuries, science became too technical and mathematical for the philosophers, or anyone else except a few specialists. Philosophers reduced the scope of their inquiries so much that Wittgenstein, the most famous philosopher of this century, said, "The sole remaining task for philosophy is the analysis of language." What a comedown from the great tradition of philosophy from Aristotle to Kant!”

“Future generations may or may not judge Wittgenstein to be one of the great philosophers. Even if they do not, however, he is sure always to count as one of the great personalities of philosophy. From our perspective it is easy to mistake one for the other; which he is time will tell.”

“If you have a room which you do not want certain people to get into, put a lock on it for which they do not have the key. But there is no point in talking to them about it, unless of course you want them to admire the room from outside! The honorable thing to do is put a lock on the door which will be noticed only by those who can open it, not by the rest.”

“I remember the revelation it was to me when I realized I'd rather be smart in the way Elvis Presley was than in the way, say, Ludwig Wittgenstein was. The thing was, you could imagine you could be smart like Wittgenstein by just thinking hard enough, but Elvis just had it. It was almost spiritual. A kind of grace.”

“Life can be a misunderstanding, if we are ignorant of the right language or don’t try to learn it. « If lions could speak, we would not understand them. » says Ludwig Wittgenstein. If we make an effort, however, we could manage to understand. ( “ Life was a misunderstanding » )”
