The Brown Book by Ludwig Wittgenstein

"We meet again and again with this curious superstition, as one might be inclined to call it, that the mental act is capable of crossing a bridge before we’ve got to it. This trouble crops up whenever we try to think about the ideas of thinking, wishing, expecting, believing, knowing, trying to solve a mathematical problem, mathematical induction, and so forth."
