there is no objective way to say it. all you can do is get most people to agree with you that some forms of killing are ok and some forms of killing are not ok. you can certainly use objective facts in your persuasion, like "you dont like pain, and being killed is painful" - or "self defense keeps us alive at the expense of lawbreakers who we dont want around anyway" - but all of these facts must necessarily play to the desires of the people you are trying to convince.
somebody who is an extreme pacifist, for example, will probably not be swayed by any attempt to convince that killing in self-defense is ok. his desire for pacifism far outweighs his desire to live.
Well, I see, then if this is as objective as it can get, then we should at least treat it as such and not try to be any
less objective. In this way have you not answered one of your previous questions when you asked if someone near a fireplace said stealing is fine? Could you not "use objective facts in your persuasion"?
If we were to debate about ethical views/morality should we not adhere to this logical construct at the very least? Yes, we can not make everyone happy, but we can create a system, albeit one based on the desires of very specific people. Then again, what is the point of this moral system if many can not come together to agree upon it?
This sounds familiar to the creation of a government or a body of people to decide upon the rules that others must follow in order to sustain stability.
Perhaps we could create such a group? Yes, but we will need this group to be powerful and commanding of at least many influential people/groups. Yes, yes, this is great, we will have a governing body that sits at the top, making generalized ethical rules, mostly their purpose will be to govern the sub-groups. Let's call these group societies, oh wait, even better,
ethical societies. These ethical societies may need even more specific sub-societies in the future, but for now they'll do.
These ethical societies will be run by a group of individuals, perhaps we will call them comities, who will be elected by those they decide ethical rules upon (voted into office if you will, "chosen by the people, to speak for the people"). Of course the top group's comity's officials will be voted upon by those who run the sub-groups.
What say you about this system? Do you see where I'm going with this?
Unfortunately for engineers such as myself(correction, engineer-to-be, I'm still in school), there is no uniting top ethical society unless you want to count the society for professional engineers. It saddens me, but without some sense of unity engineers simply won't get the respect they deserve. Also, since countries like America don't require engineering licenses to practice engineering these societies don't have as much power to actually enforce their guidelines.
Sorry that I branched off and ranted about my complaints about engineering ethical societies... or engineering in general...
