Douglas Hofstadter – Metamagical Themas (1985)
It is a curious coincidence that the only other reply to my article that was printed in the “Letters” column of Scientific American also came from the University of Delaware. Here it is:
I hope that you do not receive any correspondence concerning Douglas R. Hofstadter’s article on self-reference. I should like to inform your readers that many years of study on this problem have convinced me no conclusion whatsoever can be drawn from it that would stand up to a moment’s scrutiny. There is no excuse for Scientific American to publish letters from those cranks who consider such matters to be worthy of even the slightest notice.

I replied as follows:
Many years of reading such letters have convinced me that no reply whatsoever can be given to them that would stand up to a moment’s scrutiny. There is no excuse for publishing responses to those cranks who send them.
After these two exchanges had appeared in print, a number of people remarked to me that they’d read the two letters from Delaware that had attacked me, and had enjoyed my responses. Two? I guess it wasn’t so obvious that Dale’s letter was completely tongue-in-cheek. In fact, that was its point.
