The Brain and the Senses

"Thoughts in the Brain first
Then only sounds from the mouth.
Sounds into the ears first
Then only thoughts in the Brain.
Inputs and Outputs
Back and Forth
Between the Brain and the Senses.
That's is all there is to our lives."
So they claim
The atheists amongst us
Even as they know not
How and Why
The mind and emotions evolve
Out of processes in the Brain.
