A serious philosophical investigation must have a well-defined epistemic goal. This means that we should be able to clearly and explicitly state from the very beginning of an inquiry what we actually want to know, what exactly the objective of our considerations is. The philosophical problem of consciousness partly lies in the fact that this first step is particularly difficult: What exactly is it that we want to know? What exactly is the problem of consciousness? And when would we feel that the problem is definitively solved? Volume 1 offers 15 modules with texts by Peter Bieri, Thomas Nagel, Frank Jackson, Joseph Levine, David Chalmers, Paul Churchland, Daniel Dennett, Sydney Shoemaker, Fred Dretske, Güven Güzeldere, David Rosenthal, Thomas Metzinger, Diana Raffman, and Antti Revonsuo.
