In their everyday uses, words do their work without creating puzzles. "I know this is a hand," "she is in pain," "it is now three o'clock" — all perfectly in order in ordinary contexts. Philosophical problems arise when we try to use these same words while abstracting from those contexts: "How can anyone know anything about the external world?" "What is time, really?" "Can I ever know what another person feels?" The words are the same, but the language machine is now running in a vacuum, producing heat without traction.
The surface grammar of our language generates illusions. Because "thinking," "pain," and "understanding" are nouns, we suppose they name things — inner objects or processes. Because "time," "knowledge," and "meaning" are substantives, we look for their referents. But the grammatical form of a word need not mirror its logical function. "Five" is a noun, but it does not name an object. "Understanding" looks like "running," but understanding is not an inner act that accompanies speech in the way that running accompanies walking.
The philosopher's task is not to build a better theory but to dissolve the confusion. This means returning words to their ordinary uses, reminding ourselves of how they actually function in the language games where they belong, and resisting the temptation to look for hidden depths where there are only familiar surfaces. A philosophical problem is solved when we no longer feel the urge to ask the question — not because we have answered it but because we can see that it was never a genuine question at all.
The bewitchment formulation appears in the Blue Book and is repeated in §109 of the Philosophical Investigations. The idea that philosophy is a battle against grammatical illusion, not a search for new facts, is the methodological core of Wittgenstein's later work.
