Dennet's book, "Conciousness Explained" (

His basic idea is that conciousness is not a single type of 'thing' that happens, and does not, of itself, play the role of a decider in mental processes. Rather, it's the result of many different, unconnected, mental processes, each of which has reached a level of complexity which provides specific evolutionary advantages.
Basically the idea that conciousness is an epi-phenomena of the brian, but being more specific about how and why that occurs.
