Thanks for the links, frankiespeakin. This subject has been on the forefront of my mind lately, I started to read a book on consciousness by psychologist Susan Blackmore. The big question for me is does the 'self' actually exist at all. Buddhist thought holds that the self is illusory. The philosopher David Hume concluded that the self is not an entity, but a "bundle of sensations". Fascinating stuff.
JamesThomas, with advances in neuroscience, ideas concerning consciousness might not be just 'beliefs' much longer, but eventually acheive some scientific validity. But sometimes I think the questions are more fun than conclusive answers, anyway.
