"Starting with a passage from Gottlob Frege, Craig Dworkin replaced each of the words in Frege’s sentence with its dictionary definition. He then replaced each of the words in that new sentence with its dictionary definition, and then each of the words in the resulting sentence with its dictionary definition, and so on. DEF presents five iterations of the process using the Oxford English Dictionary and another five using the first, 1806 edition of Noah Webster’s Compendious Dictionary of the English Language."--publisher's website
