"My propositions are elucidatory in this way: he who understands me finally recognizes them as senseless, when he has climbed out through them, on them, over them. (He must so to speak throw away the ladder, after he has climbed up on it.)"
I feel like Wittgenstein made a mistake here in his choice of metaphor. If his 'ladder' were instead a 'wiener,' as in wienerschnitzel, the statement would be both more logical and more senseless. At least more nonsenseful, for as every good philosopher knows, it is much easier to throw away the wiener once you've climbed up on it.
