A legion of scientists are working to find the places in the brain responsible for qualities like creativity. Are they on a wild muse chase? Here’s Douglas Hofstadter’s opinion:

There has recently been a very strong push to connect the most complicated cognitive or emotional phenomena to the latest trends in biology and exploring the brain. People yearn to find “the” neural correlate of an emotion or even a creative thought. To me, that hope seems about as silly as trying to find the key to the greatness of a novel by closely examining the typographical symbols that compose it. Clearly, the relative frequency of “k” and “j” is ridiculously far from what makes a novel great. There are so many levels of description between the level of letters and that of ideas.

It’s noteworthy that Hofstadter’s most famous book, Gödel, Escher, Bach, does not contain the letter K or J. At least the title doesn’t, which is as far as I got.
