the only sole thing i cannot fathom, nor compute nor calculate

what i can't grasp nor grip is this:
we have autonomy and why would a pill, which merely tells the mind"Stop hurting in the left big toe?"
be superbior to the mind itself saying
"Say, left big toe? How you? say could you stop the hurthing okay, nothing to hurt about now, just leftover owies..."
THIS OUTTGHAT BE THE HUGE FOCUS OF SCIENCE AND HEALING ARTS,nay?
