I’m currently reading Zoltan Torey’s book The Crucible of Consciousness: An Integrated Theory of Mind and Brain. It’s fascinating and I will put up a review some time soon.
In the model he proposes for the self aware mind (consciousness) he deals with problems the mind has to confront. Reflective awareness can lead to chronic anxiety, fretting and anticipation of danger. Human reflective awareness has given us unique and powerful abilities but they “are not altogether a blessing. Or at least blessing that have to be paid for very dearly indeed.”
