'I suspect the real breakthroughs in our understanding of consciousness are going to come from an entirely different direction. That direction, controversially, has to do with psychedelics — which, as many of the contributors to The Divine Spark argue, offer spectacular potential for the investigation of the 'hard problem' of consciousness.' — from the introduction by Graham Hancock
