A truncated thread from Facebook:

Peter: …To allow IS to determine.

Chris Fisher: I allow my children to fight by not tying them up with ropes and leaving them in a closet all day. But that doesn’t mean I am determining it.

Peter: Chris Fisher if you allowed them to fight and one of them hurt the other, would you be responsible?

Chris Fisher: Absolutely not. I have no positive requirement to act. Not-acting is the default. That would be like saying you are responsible for people starving in Africa because you don’t dedicate all your non-subsistence income to Africa.

Nathan: No Chris Fisher, take it even further, the logic of Peter would be that not only is he responsible for people starving in Africa, but he’s determining their starvation by not acting.

Chris Fisher: Peter, decreeing and determining people to starve to death in Africa. That’s not nice of you, Peter, to determine such a thing.
