Author

[original bio from 1982.] Douglas R. Hofstadter is an associate professor in the Computer Science Department at Indiana University (Bloomington, IN, USA). Immediately after receiving his Ph.D. in physics, he wrote Gödel, Escher, Bach: an Eternal Golden Braid (Basic Books, 1979), a book about mentality and consciousness, and their relation to abstract structures. He conducts research in artificial intelligence, concentrating on the higher-level aspects of perception, and how they are related to generalization, abstraction, and induction. His project Letter Spirit in particular is concerned with the notion of style in alphabets; his goal is to have it be able to extrapolate an entire typeface from a few sample letters given to it. He has co-edited, with philosopher Daniel Dennett, an anthology of fantasies and reflections on self and soul: The Mind’s I (Basic Books, 1981). He also writes a column entitled “Metamagical Themas” each month in Scientific American.

[bio for 2026.] Douglas R. Hofstadter is a distinguished professor of cognitive science at Indiana University (Bloomington, IN, USA). He recently added Ambigrammia: Between Creation and Discovery (ABCD; Yale University Press) to his list of authored books. ABCD contains hundreds of ambigrams, defined as “a piece of writing expressly designed to squeeze in more than one reading” (Hofstadter, 2025, p. 1). In the example below, each color name can be read forward and also in a mirror. The final instance actually has four readings, with DOUG (the ambigram’s creator) and 2006 (its year of creation) simultaneously readable both forward and backward. In his I Am a Strange Loop (Basic Books), published earlier in 2007, Hofstadter offers one of his “firmest conclusions”: “we always think by seeking and drawing parallels to things we know from our past, and… we therefore communicate best when we exploit examples, analogies, and metaphors galore, when we avoid abstract generalities, when we use very down-to-earth, concrete, and simple language, and when we talk about our own experiences” (Hofstadter, 2007, p. xv). Among other down-to-earth intellectual contributions in simple language, he is known for Hofstadter’s Law (p. xv): “It always takes longer than you think it will take, even when you take into account Hofstadter’s Law.”
