“Two times two will be four even without my will. Is that what you call man's free will?”

“But gentlemen, what sort of free choice will there be when it comes down to tables and arithmetic, when all that’s left is two times two makes four? Two times two makes four even without my will. Is that what you call free choice?"— Fyodor Dostoyevsky”

“You don't need free will to determine that twice two is four. That's not what I call free will.”

“There comes a time in history when the man who dares to say that two and two make four is punished with death. The schoolteacher is well aware of this. And the question is not one of knowing what punishment or reward attends the making of this calculation. The question is that of knowing whether two and two do make four.”

“But again and again there comes a time in history when the man who dares to say that two and two make four is punished with death. The schoolteacher is well aware of this. And the question is not one of knowing what punishment or reward attends the making of this calculation. The question is one of knowing whether two and two do make four”

“My math is so fuzzy you should pet it. Four minus two isn’t two, because between two and four minus two is an infinite number of numbers.”
