Somewhere on that journey, consciousness happens, according to Paul Broks' excellent review of Seeing Red. This is the best book review (in the format of a standalone essay) that I've read in a long time, and it's even got a cliffhanger! Have a go at it, and then I am sure you'll be in for its object, too (via virtual philosopher).
Btw, when did you order your first book online? My first traceable Amazon order happened on 11 August 1998: Paul Krugman's Accidental Theorist and Clayton Christensen's The Innovator's Dilemma.
