§112

Philosophical problems can be the upshot of misconceiving a simile absorbed into language. One the one hand we think that our philosophical conclusions are absurd or incredible (or at least that they don't accord with our ordinary use of language) and yet on the other hand (gripped by the model/picture we've adopted) we think 'this is how things must be'. We project necessary/conceptual connections onto the world - and conceptual connections that do not in fact hold.
