Biography of Douglas Hofstadter
Martin Gardner's Scientific American column "Mathematical Games" was succeeded in the early 1980s by Hofstadter's anagrammatically titled "Metamagical Themas": these and other essays, including discussion of Memes and a fictional illustration of probability mathematics, are assembled as Metamagical Themas (coll 1985). Le Ton beau de Marot: In Praise of the Music of Language (1997), another large, idiosyncratic and digressive volume, focuses on Linguistics and issues of translation. Portions of this have been criticized as amateurish by some linguists, but there is interesting and provocative commentary on several sf/fantasy authors including Poul Anderson, Dante Alighieri, Robert L Forward and Stanisław Lem (the last as translated by Michael Kandel in particular). A further meditation on the themes of The Mind's I, which also retraces part of the GEB exposition with fresh perspectives and analogies, is I Am a Strange Loop (2007); featured sf Thought Experiments include Matter Transmission, Matter Duplication and the "Twinwirld" Alternate World in which identical twins are the norm and each pair effectively shares a single identity.
