Douglas Hofstadter (author of Gödel, Escher, Bach and many other books) is in town this week. He gave a lecture to our Phil.of Mind class at Tufts entitled “What is it like to be a strange loop?”, and he’s talking at the Media Lab in MIT tomorrow.
As to the subject of the talk:
(1) Hofstadter remains fascinated (as he was in GEB) with the interaction of two ideas: feedback loops, and systemic (explanatory) levels. In GEB, you may remember, the strange – and unexpectedly stable – patterns generated by pointing a video camera at the screen displaying its output were a powerful example (and metaphor) for the way these ideas come together. Doug’s about to repeat a number of those experiments: how will the fact that the low-level technology has changed from analog to digital affect them?
(2) My interpretation of “strange loops” is that Doug is talking about feedback loops that cross various kinds of boundaries: between the physical and the cognitive, between the outside world and the I-in-the-world (in terms of action and perception), and across minds (from one person to another).
After the lecture, a bunch of us went out for dinner with Dennett and Hofstadter. Among the faculty and students, was an old friend, the novelist and tech writerJohn Sundman. He and I worked together at Sun from 1986 until about 1989; John did most of the writing on the first release of PC-NFS, and managed the writing for the 386i workstation program.
