Reason is universal because no attempted challenge to its results can avoid appealing to reason in the end-by claiming, for example, that what was presented as an argument is really a rationalization.

Consciousness is what makes the mind-body problem really intractable.

The great cognitive shift is an expansion of consciousness from the perspectival form contained in the lives of particular creatures to an objective, world-encompassing form that exists both individually and intersubjectively. It was originally a biological evolutionary process, and in our species it has become a collective cultural process as well. Each of our lives is a part of the lengthy process of the universe gradually waking up and becoming aware of itself.

The universe has become not only conscious and aware of itself but capable in some respects of choosing its path into the future--though all three, the consciousness, the knowledge, and the choice, are dispersed over a vast crowd of beings, acting both individually and collectively.
