“Tell me, what kind of functions does pain have when one is convicted to 100 whippings in Saudie Arabia? You claim pain has a function, I claim that's scientific rubbish. The only thing pain really does is cause an instant reaction that is not rational and usually quite erratic. The famous example of the hand in boiling water, for example. You say it proves pain has a function. But exactly because of the spasmic reaction lots and lots of people will drop the bowl with boiling water over their entire bodies causing serious burns. So what was the 'function' of this pain? Pain and fear cause confusion and trauma. If pain actually did have a rational function, chronic pain would not exist.”
