This picture was drawn by Douglas Hofstadter for his classic dialogue “Prelude…Ant fugue” in his masterful Godel, Escher, and Bach. In the dialogue he asked a simple, yet highly illuminating question: what does the picture say?
On the top level, it says “MU”, alluding to the Zen parable of Joshu and the dog. In this parable, a monk asks Joshu “does a dog have Buddhe-nature?” Joshu, with immediate fervor, replies “MU!”, which basically means that Joshu denied the legitimacy of the question. He “unasked” the question. The relevance of the parable is made clear when one attempts to answer the above question: what does the picture say? One cannot simply assert that it says “MU”, although on the top and bottom levels it says as much.(You can’t see it in the above copy, but the individual letters are made out of tiny iterations of “mu”). That would be too simplistic of an answer, although it is trivially “true”.
The beauty of Hofstadter’s diagram is only apparent after you let the meaning of the parable sink in. Do all questions have definite answers? Can we really ask questions like “Is the key approach to the mind reductionist or holist?” and expect simple answers? Is it wiser to instead “unask” such questions? Perhaps that question should be unasked as well!
I love this diagram on multiple levels, which is fitting I think, so I thought I would share it with you all. Please spend the time to ponder on the question of what the picture reallysays, and see if you come to the same conclusion as Joshu.
