Douglas Hofstadter – Metamagical Themas (1985)
It always seems refreshing to see how magazines, in their letters columns, willingly publish letters highly critical of them. I say “seems”, because often those letters are printed in pairs, both raking the magazine over the coals but from opposite directions. For example, a right-wing critic and a left-wing critic both chastise the magazine for leaning too far the wrong way. The upshot is of course that the magazine doesn’t even have to say a thing in its own defense, for it is a kind of cliché that if you manage to offend both parties in a disagreement, you certainly must be essentially right! That is, the truth is supposedly always in the middle—a dangerous fallacy.
