Subtlety and predictability are not exclusive.
I know. However, all that we've established is that water acts in predictable ways.
you might have a nervous impairment
Without hydrogen, water is oxygen and no longer turns to ice at zero degrees centigrade. However ice remains predictable, just as a hand with a working central nervous system held over a stove remains predictable. Changing my working reflexes into something else doesn't make my working reflexes unpredictable.
Nor is it 100% predictable that you will withdraw your hand from a hot stove. For all I know you might be a lunatic
If I was a lunatic, I could not stop withdrawing my hand. It is an automatic reflex. No matter what belief or thought I held I would withdraw my hand.
This indicates to me that the response is not conscious. Do you agree with me, or can you argue that the response is conscious?
