Read full description of the books:



Nel 1979 un giovane professore dell'Università dell'Indiana, Douglas Hofstadter, sorprese il mondo con un libro di enorme mole, labirintico, geniale e di immenso successo, Gödel, Escher, Bach, basato sulla tesi che la chiave dell'anima umana risiedesse in una struttura astratta in forma di anello. A trent'anni di distanza, molte cose sono cambiate, i computer hanno invaso le nostre vite e gli studi sul cervello hanno raggiunto un grado di dettaglio impressionante. Eppure, resta intatto l'ultimo mistero: dove si trova e come è fatta l'anima? Cos'è che chiamiamo "io" quando parliamo di - o con - noi stessi? Cosa resta (se resta qualcosa) dopo la nostra morte fisica?
Confermando in pieno le sue doti di scrittore originalissimo, capace di metafore illuminanti, di invenzioni lessicali dai molteplici livelli semantici, di giochi di prestigio e d'artificio linguistici e narrativi, in questo nuovo libro Hofstadter ci offre la summa dei suoi studi, una riflessione profonda e personale sui temi e i quesiti centrali della filosofia e della spiritualità, dall'anima alla volontà, dal libero arbitrio alla coscienza.

Read information about the author

Ebook Anelli nell'io. Che cosa c'è al cuore della coscienza? read Online! Douglas Richard Hofstadter is an American academic whose research focuses on consciousness, thinking and creativity. He is best known for his book Gödel, Escher, Bach: an Eternal Golden Braid, first published in 1979, for which he was awarded the 1980 Pulitzer Prize for general non-fiction.

Hofstadter is the son of Nobel Prize-winning physicist Robert Hofstadter. Douglas grew up on the campus of Stanford University, where his father was a professor. Douglas attended the International School of Geneva for a year. He graduated with Distinction in Mathematics from Stanford in 1965. He spent a few years in Sweden in the mid 1960s. He continued his education and received his Ph.D. in Physics from the University of Oregon in 1975.

Hofstadter is College of Arts and Sciences Distinguished Professor of Cognitive Science 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 at that time he called "artificial intelligence research", a label that 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, and also was appointed Adjunct Professor of History and Philosophy of Science, Philosophy, Comparative Literature, and Psychology, but he states that his involvement with most of these departments is nominal.

In April, 2009, Hofstadter was elected a Fellow of the American Academy of Arts and Sciences and a Member of the American Philosophical Society.
Hofstadter's many interests include music, visual art, the mind, creativity, consciousness, self-reference, translation and mathematics. He has numerous recursive sequences and geometric constructions named after him.

At the University of Michigan and Indiana University, he co-authored, with Melanie Mitchell, a computational model of "high-level perception" — Copycat — and several other models of analogy-making and cognition. The Copycat project was subsequently extended under the name "Metacat" by Hofstadter's doctoral student James Marshall. The Letter Spirit project, implemented by Gary McGraw and John Rehling, aims to model the act of artistic creativity by designing stylistically uniform "gridfonts" (typefaces limited to a grid). Other more recent models are 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.

Hofstadter collects and studies cognitive errors (largely, but not solely, speech errors), "bon mots" (spontaneous humorous quips), and analogies of all sorts, and his long-time observation of these diverse products of cognition, and his theories about the mechanisms that underlie them, have exerted a powerful influence on the architectures of the computational models developed by himself and FARG members.

All FARG computational models share certain key principles, among which are: that human thinking is carried out by thousands of independent small actions in parallel, biased by the concepts that are currently activated; that activation spreads from activated concepts to less activated "neighbor concepts"; that there is a "mental temperature" that regulates the degree of randomness in the parallel activity; that promising avenues tend to be explored more rapidly than unpromising ones. FARG models also have an overarching philosophy that
