David J Moser Biography & Facts

Douglas Richard Hofstadter (born February 15, 1945) is an American cognitive and computer scientist whose research includes concepts such as the sense of self in relation to the external world, consciousness, analogy-making, strange loops, artificial intelligence, and discovery in mathematics and physics. His 1979 book Gödel, Escher, Bach: An Eternal Golden Braid won the Pulitzer Prize for general nonfiction, and a National Book Award (at that time called The American Book Award) for Science. His 2007 book I Am a Strange Loop won the Los Angeles Times Book Prize for Science and Technology. Early life and education Hofstadter was born in New York City to future Nobel Prize-winning physicist Robert Hofstadter and Nancy Givan Hofstadter. He grew up on the campus of Stanford University, where his father was a professor, and attended the International School of Geneva in 1958–59. He graduated with distinction in mathematics from Stanford University in 1965, and received his Ph.D. in physics from the University of Oregon in 1975, where his study of the energy levels of Bloch electrons in a magnetic field led to his discovery of the fractal known as Hofstadter's butterfly. Academic career Since 1988, Hofstadter has been the College of Arts and Sciences Distinguished Professor of Cognitive Science and Comparative Literature at Indiana University in Bloomington, where he directs the Center for Research on Concepts and Cognition which consists of himself and his graduate students, forming the "Fluid Analogies Research Group" (FARG). He was initially appointed to the Indiana University's Computer Science Department faculty in 1977, and at that time he launched his research program in computer modeling of mental processes (which he called "artificial intelligence research", a label he has since dropped in favor of "cognitive science research"). In 1984, he moved to the University of Michigan in Ann Arbor, where he was hired as a professor of psychology and was also appointed to the Walgreen Chair for the Study of Human Understanding. In 1988 he returned to Bloomington as "College of Arts and Sciences Professor" in both cognitive science and computer science. He was also appointed adjunct professor of history and philosophy of science, philosophy, comparative literature, and psychology, but has said that his involvement with most of those departments is nominal. In 1988 Hofstadter received the In Praise of Reason award, the Committee for Skeptical Inquiry's highest honor. In April 2009, he was elected a Fellow of the American Academy of Arts and Sciences, and was a member of the American Philosophical Society. In 2010, he was elected a member of the Royal Society of Sciences in Uppsala, Sweden. At the University of Michigan and Indiana University, Hofstadter and Melanie Mitchell coauthored a computational model of "high-level perception"—Copycat—and several other models of analogy-making and cognition, including the Tabletop project, co-developed with Robert M. French. The Letter Spirit project, implemented by Gary McGraw and John Rehling, aims to model artistic creativity by designing stylistically uniform "gridfonts" (typefaces limited to a grid). Other more recent models include Phaeaco (implemented by Harry Foundalis) and SeqSee (Abhijit Mahabal), which model high-level perception and analogy-making in the microdomains of Bongard problems and number sequences, respectively, as well as George (Francisco Lara-Dammer), which models the processes of perception and discovery in triangle geometry. Hofstadter has had several exhibitions of his artwork in various university galleries. These shows have featured large collections of his gridfonts, his ambigrams (pieces of calligraphy created with two readings, either of which is usually obtained from the other by rotating or reflecting the ambigram, but sometimes simply by "oscillation", like the Necker Cube or the rabbit/duck figure of Joseph Jastrow), and his "Whirly Art" (music-inspired visual patterns realized using shapes based on various alphabets from India). Hofstadter invented the term "ambigram" in 1984; many ambigrammists have since taken up the concept. Hofstadter collects and studies cognitive errors (largely, but not solely, speech errors), "bon mots", and analogies of all sorts, and his longtime observation of these diverse products of cognition. His theories about the mechanisms that underlie them have exerted a powerful influence on the architectures of the computational models he and FARG members have developed. Hofstadter's thesis about consciousness, first expressed in Gödel, Escher, Bach but also present in several of his later books, is that it is "an emergent consequence of seething lower-level activity in the brain." In Gödel, Escher, Bach he draws an analogy between the social organization of a colony of ants and the mind seen as a coherent "colony" of neurons. In particular, Hofstadter claims that our sense of having (or being) an "I" comes from the abstract pattern he terms a "strange loop", an abstract cousin of such concrete phenomena as audio and video feedback that Hofstadter has defined as "a level-crossing feedback loop". The prototypical example of a strange loop is the self-referential structure at the core of Gödel's incompleteness theorems. Hofstadter's 2007 book I Am a Strange Loop carries his vision of consciousness considerably further, including the idea that each human "I" is distributed over numerous brains, rather than being limited to one. Le Ton beau de Marot: In Praise of the Music of Language is a long book devoted to language and translation, especially poetry translation, and one of its leitmotifs is a set of 88 translations of "Ma Mignonne", a highly constrained poem by 16th-century French poet Clément Marot. In this book, Hofstadter jokingly describes himself as "pilingual" (meaning that the sum total of the varying degrees of mastery of all the languages that he has studied comes to 3.14159 ...), as well as an "oligoglot" (someone who speaks "a few" languages). In 1999, the bicentennial year of the Russian poet and writer Alexander Pushkin, Hofstadter published a verse translation of Pushkin's classic novel-in-verse Eugene Onegin. He has translated other poems and two novels: La Chamade (That Mad Ache) by Françoise Sagan, and La Scoperta dell'Alba (The Discovery of Dawn) by Walter Veltroni, the then-head of the Partito Democratico in Italy. The Discovery of Dawn was published in 2007, and That Mad Ache was published in 2009, bound together with Hofstadter's essay Translator, Trader: An Essay on the Pleasantly Pervasive Paradoxes of Translation. Hofstadter's Law Hofstadter's Law is "It always takes longer than you expect, even when you take into account Hofstadter's Law." The law is stated in Gödel, Escher, Bach. Students Hofstadter's former Ph.D. students include (with dissertation title): David Chalmers – Toward a Theory of Consciousness Bob French – Tabletop: An Emergent,....
