Listen to British rocker Jarvis Cocker read the story “Descent of Species” from Sum. He is one of the dozens of terrific voices who read for the audio book. Jarvis is known for his raw and edgy albums such as Jarvis and Further Complications.

"David Eagleman offers startling lessons.... His method in both Sum and his new book, Incognito, is to ask us to cast off our lazy, commonplace assumptions."
- The Guardian
"What Eagleman seems to be calling for is a new Enlightenment."
- Sunday Herald
"David Eagleman is the kind of guy who really does make being a neuroscientist look like fun."
- New York Times
"Eagleman has a talent for testing the untestable, for taking seemingly sophomoric notions and using them to nail down the slippery stuff of consciousness."
- The New Yorker
"[A] neuroscientist and polymath."
- Wall Street Journal
"A popularizer of impressive gusto...[Eagleman] aims, grandly, to do for the study of the mind what Copernicus did for the study of the stars."
- New York Observer
"David Eagleman may be the best combination of scientist and fiction-writer alive."
- Stewart Brand
