What? I asked you what are your uncertainties about the immorality of the acts that you say you “think” are immoral. And I don't have a clue as to how anything you said here is supposed to relate to a possible answer to my question. (What does “it” in your first sentence refer to?)
Apparently, I have as difficult a time understanding you. I can't answer your question, for example, because I don't know which "first sentence" you're referring to. The first sentence in the post you quoted doesn't contain an "it."
I will ask my question in a different way. When you say that you “think” that ripping the heart out of a living person in a act of sacrifice is “wrong” or immoral, why do you “think” that such an act is wrong or immoral? What is your premise by which you have come to have that thought?
I "think" it is wrong because the only possible thing that could make it "right" is the unassailable demand of a GOD that it be done. I don't believe in gods, nor have I ever seen any evidence of such an unassailable demand. For me, then, it is immoral because it does unquestionable harm to the person whose heart is being ripped out, because I would not want it done to me, and there appears to be no compelling (i.e. god-commanded) reason to do so.
But is my argument valid for somebody born into a community where such a belief is socially ingrained and inculcated into community members from infancy? How would you deny it? Prove that their god doesn't exist, or doesn't demand such sacrifice? How will you do that?
Do you not agree that one should use reason in determining what acts are moral acts and what acts are immoral?
Certainly I agree, and have said so. Just be clear, though, that reasoning (in the way you are about to use it, requires that you have some axiom or premise that you accept as true. The reasoning falls if the premise is false, after all.
Let us deduce that rape of a 4-year-old child is an immoral act:
P1: All human acts that harm a person, are perpetrated without that person's consent and are perpetrated merely for the perpetrator's pleasure are immoral acts.
P2: Rape of a 4-year-old child is a human act that harms the child, is perpetrated without that child's consent and is perpertrated merely for the perpetrator's pleasure.
C: Therefore, rape of a 4-year-old child is an immoral act.
M = P.
S = M.
Therefore, S = P.
(AAA-1)
Did you leave out the overriding premise?
P0: Everything demanded by heaven (or god) is mandatory no matter what else you might think.
Now, in the case of the rape of a 4-year-old child, perhaps I may not find a religion in that was heaven-directed. But in the case of human sacrifice, I can find many. I rather suspect that the Taliban in Afghanistan could find scriptural (i.e. heavenly) justification for shooting veiled women in the middle of a stadium before an audience of soccer watchers. I suppose. Certainly the thousands in the stands didn't swarm the dozen on the field doing the shooting, so what should I believe?
How would you deduce that rape of a 4-year-old child is a moral act? What premises would you use to deduce that rape of a 4-year-old child is a moral act? If you can't think of any premises by which to deduce that rape of a 4-year-old child is a moral act, then you obviously cannot use reason to deduce that such an act is moral.
I could not, of course, deduce any such thing -- nor have I so far in this debate -- for the simple reason that I do not accept any deities many any demands on any of us. Therefore, I cannot use that overriding premise ("P0" above) in my reasoning. But am I the measure of all humans?
I would argue that you are not a fact but a person, and that a Mercedes-Benz is not a fact but an automobile.
This is a bit of word-play that I don't find helpful in our discussion. If it is a fact that I am a person, than I am also that fact. It is a fact that the gun identified in a murder trial is, indeed, a gun. It is also, by definition, a "fact in evidence."
Facts are not objects that have a spacetime location. Facts are propositions that are true. A couple of examples of objective mathematical facts would be: all plane right triangles obey the relation a2 + b2 = c2 (Pythagorean theorem); and: the power set of a countably infinite set is of greater cardinality than the countably infinite set (consequence of Cantor's Theorem). A presumably true objective fact of physics is the mathematical relation E=mc2. An undeniably true objective fact of physics is that quantum mechanics is statistical.
Still word-play that I consider limiting. That I am the person that I think I am, occupying this place in time and space is an objective truth -- a fact. (In my humble view.)
In the context of moral realism, “objective” in the phrase “objective moral fact” just means that the fact is not a subject experience--it is a fact regardless of whether anyone is thinking it.
And I contend that I am sitting here communicating with you, whether you, I or anybody else thinks so. In that sense, I am an objective, moral fact (which happens to be susceptible to subjective experience).
In any case, what did you mean by your statement that you want to act ethically? Your statement certainly indicates that by "behav[ing] ethically" you do not mean merely having a subjective experience of some sort. What is entailed by the goal you express by that statement? Does “behav[ing] ethically” include you lying under oath about the whereabouts of your bothersome neighbor so that he will be wrongly convicted of a crime and no longer bothersome to you? How would you determine whether you have acted ethically?
Why don't you want to behave unethically?
I want to act ethically because of my understanding of how my existence within my community (and community of communities) tells me what works and what doesn't -- for me, for the community, and reciprocally, because they health of the community impacts on me.
And because I feel better when I do.
And because I know when I am lying, and I know how a lie can cause harm, having had the experience of being lied about.[/quote]
Obviously one can recognize the existence of other conscious beings without formulating a moral rule about one's own behavior.
Here's a little challenge for you: suppose you notice that an co-worker has a package of one of your favourite snacks at their desk, and you comment on it. Suppose, further, that this nice individual agrees with you: "Oh yes, they're my favourite, too! Help yourself to all you want."
Now, you have been given explicit carte-blanche to do exactly as you will: will you take the entire package?
