Reality is not a thought experiment.

without the mind the body is not capable of delivering anything beyond an average performance.

The moment you establish a line of communication between two points, you subtly change both. That is also true for the way the brain is affected by the mind.

The brain works in a holistic, cooperative way that makes our basest desire or most abject fear as expressive of who we are as abstract thinking of the highest order. That means that we are all equal part snakes, monkeys, and spacemen.
