Self-reference, once again, once again

Another comment, this time from the biologist Richard Dawkins, that shows that importance of self-reference:

"Perhaps consciousness arises when the brain's simulation of the world becomes so complete that it must include a model of itself."

Richard Dawkins, The Selfish Gene, Chapter 4, The gene machine.

See this post and this one on self-reference. See also the last line of G. Chaitin quoted in this post.
