The matter of the existence of consciousness has been a philosophers fight of the ages, and to just be, the struggle of budist monks for the past thousands of years... We must exist in the center, neither too self conscious, neither too little. Else, life will become totally unbearable. Of course we will have times to roam into deep introspection as well as into selfless abandonment, but I feel that even the negation of consciosness serves as it's own affirmation. It's a circular debate.
At least, that's what I think.
