And what does any of this have to do with pilots or Westworld or tinnitus or friendly fire or a wristband with vibratory motors? We don’t detect most of the action going on in the world around us… and today we’ll explore how technology might change that.

- New York Observer
"[A] neuroscientist and polymath."
- Wall Street Journal
"David Eagleman may be the best combination of scientist and fiction-writer alive."
- Stewart Brand
"What Eagleman seems to be calling for is a new Enlightenment."
- Sunday Herald
"David Eagleman offers startling lessons.... His method is to ask us to cast off our lazy commonplace assumptions.
