A footnote from an old essay of mine:

Think of the instructive amphiboly in the (translation of the) concluding line of PI 109:  “Philosophy is the battle against the bewitchment of our intelligence by means of language.”  How is this to be understood?  Is it (1) “Philosophy is the battle against the-bewitchment-of-our-intelligence-by-means-of-language” or (2) “Philosophy is the battle against the-bewitchment-of-our-intelligence by means of language”?

And then in the text proper:

The very thing which is to free us from confusion is the very thing which confused us to begin with.  The poison is also the antidote.
