Do not have methods to study it yet. Poorly defined third position is that consciousness is produced by activity of brain and that we should be optimistic about our ability to understand it (hebb) Consciousness is awareness of processes in brain, not processes themselves. Consciousness does not exist humans have ability to be conscious. Most likley explanation for consciousness lies in its relation to deliberate, symbollic communicaion our ability to communicate (words, signs, other symbollic meaning) provides us with self-awareness --> social phenomenon (like communication) Consciousness and the ability to communicate through communicating symbolically we can express our needs, thoughts, perceptions, memories, intentions, and feelings to other people require 2 general capacities: Must be able to translate private events (needs, thoughts, etc) into symbolic expressions. Brain mechanisms we use to communicate with others must receive input from systems of brain involved in perceiving, thinking , remembering, etc. Our symbols (words) must have effect on other person listening.
