  • You don't need to be intelligent to work that out! And a brain is only something with which we think that we think.

  • We call the brain's internal capabilities Intelligence. It is convenient to
    give a similar name to all of the external influences, cultural or otherwise,
    that affect the evolution of the brain, and with it, the mind. We shall call
    these influences Extelligence. Mind is not just intelligence plus
    extelligence, its inside and outside, so to speak. Instead, mind is a feedback
    loop in which intelligence influences extelligence, extelligence influences
    intelligence, and the combination transcends the capabilities of both.
