“[…] but you seem to be missing the point about denying unlimited hypotheticals.” [DavidOdden]
No I’m not. I grant that hypotheticals that alter the very metaphysical conditions of ethical situations are unreasonable for testing ethical propositions.
“I simply reject impossible hypotheticals.”
No hypothetical in front of us is impossible simply for being hypothetical.
Do you believe we can meaningfully talk about the ethics of fictional characters and fictional situations, such as in novels? If so, then we can meaningfully talk about fictional situations such as those that have been mentioned.
“[…] if you’re talking about field commanders, you are not talking about bank robbers, and you are talking about war.”
Not necessarily. It could be a field commander of a SWAT or of any domestic police.
“In case (1), that would not be relevant, unless you mean “negligible”. If there were good reason to have thought that a projected land invasion would have led to negligible loss of life and property, then the use of nukes would have been immoral.”
What is negligible? How many losses? On the other hand, if there were Allied losses of, say, a thousand men, but civilian losses of say, a million from dropping atomic bombs, what would your answer be? Where do you draw your line? Or no line? One Allied loss as opposed to the entire civilian population of a nation?
(“2) That would depend on whether it was aggression against the US. If so, if would not matter whether it was an attack specifically against Hawaii.”
Of course I didn’t mean to confine to Hawaii specifically. Anyway, the general question can be reset: What if Japan had not attacked the U.S. but instead the U.S., in the interest of thwarting further Japanese agression that was likely to endanger the U.S., had first attacked Japanese forces in the Pacific?
“(3) If the attack had been insufficient to get them to terminate their aggression, that would have made an even more compelling argument for building and using bigger and better bombs.”
So there’s no limit to how many civilians you can morally kill?
“(6) Sorry, I can’t make any sense out of that case: what do you mean? What are we doing? How?”
What doesn’t make sense? We can consider cases that have less and less damage to ourselves but have greater and greater damage to bystanders. The point is to get a sense of how great a damage to ourselves is required to justify how much damage to bystanders? If the formula is absolute, then any damage or threat of damage to ourselves, no matter how tiny, would justify any damage, no matter how great, to bystanders, in case we couldn’t avoid that damage to bystanders to protect ourselves from further damage or threat of damage. If the formula is not absolute, then we need to know where on the continuum lies the particular incidents in 1945.
“You say, but I don’t see how.”
Anyway we want by gradually decreasing (or increasing) hypothetical damage to ourselves and increasing (decreasing) hypothetical damage to bystanders.
“It is never the case that the only way to stop a bank robber is by setting off a nuke. I have no problem grappling with hypotheticals, but they have to be possible (I hope you understood the reason why – “Now suppose you were immortal and always guaranteed of success. Then would it be moral to…”).”
First, I already answered your objection about metaphysical contrafactuals.
Second, that in our present circumstances a nuke is never needed for a robber doesn’t detract from the point of the hypothetical. If you like, take the situation as fictional…but I’m not asking you to take the situation as metaphysically fictional!
"[…] if that were the case, which it manifestly was not.?
You mean in your ethical theory two people who are both rational and have the same information can disagree about the moral permissibilty of an act?
"I said something stronger: that there is little chance that the criminal would be stopped, and that it was virtually guaranteed that innocents would be harmed. I assume you recall what I said about pointless destruction. You were incorrectly focusing on the possibility of collateral damage with no consideration for whether the purpose of the action could be satisfied. "
Fine. Then the original question is not answered: What if the only way to stop the robber were to fire shots that had a good chance of striking bystanders (you may add to this that firing enough shots will have a very very good chance of stopping the robber)? Whatever quibbles you may have with how much of a chance of stopping the robber, etc., the basic point of the original assertion was clear enough: There is no unlimited moral right to endanger bystanders just to apprehend an initiator of force.
“Only a pacifist takes the protection of the lives of enemy non-combatants to be a moral absolute.”
Did someone say anything about protection (actually not protection, but restraint from force that includes force against) civilians as an absolute?
