A bat might not have a "personal point of view" in the human sense, but that doesn't mean there is no point of view at all
All the qualia, subjective stuff etc. is just shorthand, for whta ultimately boils down to actions in the world.
How do we talk about ethics in terms of actions, reactions abd brain scans please? That looks like an uncovered check.
In what sense are they a shorthand for actions in the world?
But you did not answer my question on how we talk about ethics in terms of actions and brain scans.
The devil is in the details, and when you try to express why it is bad to kill people over a small argument in terms of actions etc., then you might find that this is not as simple as you insinuated.
"There is no 'ethic' in nature" is also easy said in the armchair, but becomes a lifeless abstraction pretty fast when confronted with real human suffering and tears.
