What Is Your Dangerous Idea?, edited by John Brockman (Simon & Schuster, £12.99)
The results of the 2005 Question at edge.org, posed by Steven Pinker , are in. Apart from an exasperating section about "memes" (are they still fashionable?) and a few Eeyorish dullards, it's a titillating compilation. Physicist Freeman Dyson  predicts that home biotech kits will become common; others posit that democracy may be a blip and "on its way out", that "heroism" is just as banal as evil, and that it will be proven that free will does not exist. There are also far-out but thought-provoking notions: that, given the decadent temptations of virtual reality, the only civilisations of any species that survive to colonise the galaxy will be puritan fundamentalists; or that the internet may already be aware of itself. I particularly enjoyed cognitive scientist Donald D Hoffman's  gnomic pronouncement that "a spoon is like a headache", and mathematician Rudy Rucker's  robust defence of panpsychism, the idea that "every object has a mind. Stars, hills, chairs, rocks, scraps of paper, flakes of skin, molecules". Careful what you do with this newspaper after you've read it.
