Appearance does not mean fact.
Bob gets angry and hits Ted.
It appears Bob made the choice to hit Ted.
The night before he ate a lot of rancid food and drank a lot,
this knocked his hormones off balance, which created increased irritablity and agitation.
His environment made his choice for him, but now that event will be followed by a reaction.
Bob will get arrested.
Bob gets out of prison, bobs experience in prison creates more changes in his Psyche.
then Bob says no next fight because of his experience of being a prisoner.
It appears like Bob is making choices and is responsible, but this is an illusion created by seeing a person as independent from the rest of reality.
But realizing that the body is part of the enviroment, we can realize how environmental factors make a brains choices before it makes them.
Ever hear of repeat offenders?
And the food doesn't stop 'bob' from becoming a beast as he works out and learns to defend himself in prison.
I don't believe chemistry is the culprit.
And whether it is or isn't....once we are free of our chemistry we become what we truly are.
That said.....what if bob was of spirit that chemistry would have made no difference?
Beefing up in prison would be a sign of acceptance.
He would adapt.....willfully.
And he would come out of prison.....socially adjusted?
If chemistry is the culprit......then you ARE going to condone....
use of drugs in prison to pacify the inmates.
And maybe we should all be smoking something.
I used to hear the hippies say......'mellow out man....mellow out.....'
