The linguists at Language Log have noticed a form of plausible gibberish they have dubbed "Escher sentences", such as:
More people have written about this than I have
The amazing thing about these sentences is that they seem utterly plausible and sensical at first glance although they are profoundly resistant to complete comprehension. Trying to dissect and understand the sentence is a similar experience of cognitive dissonance to that of trying to fully comprehend one of M.C. Escher's famously paradoxical drawings of stairs. Looking at the steps in "Ascending and Descending", following the lines, one's mind and one's eyes try to comprehend how this loop has happened, but the human apparatus itself is short-circuited by this "golden braid". Examples of similar psychosensory phenomena include Shepard tones and this picture-in-picture zoom pointed out recently at What is FliG?.
The example sentence above seems to communicate to me something like "Other people have written more about this than I have", but that's not what it says!
How can such a sentence be constructed, or understood? Is there a missing or implied word?
If it had not been pointed out, I would never have even noticed the incongruity of these sentences. Even so, I have to concentrate to see the incongruity and not apply the approximating gloss. Funny to catch the mind looping back on itself in this way.
