I'm a devoted listener of StarShipSofa's Aural Delights science fiction podcast. The most recent episode (No. 37) has a short story by Ted Chiang called "What's Expected Of Us," and I think it's comparable to the work of Jorge Luis Borges.
"What's Expected Of Us" is about what happens after the introduction of a little toy called The Predictor. It looks like a car-door remote. It has one button and one LED. It does one thing, and one thing only: without fail, its LED flashes precisely one second before you push the button.
Chiang's exploration of the consequences of such a gadget packs the same kind of philosophical wallop that makes The Mind's I (Hofstadter and Dennett) one of the most mind-altering books I've ever read.
Cory gave me a copy of Chiang's Stories of Your Life and Others, a thought-provoking collection of short fiction.
