Uh, first off, thanks for that Philosophy of Science tidbit. That's another area where I've wanted to study, but havent had time.Kuroneko wrote:...The most famous alternative, implicitly found in almost every description of "the scientific method" (questions on the applicability of this label notwithstanding) is Popperian falsificationism: simply take the best best-performing model not known to be false. It's important to distinguish induction in the sense of abstracting patterns from data and induction in the sense of assigning truth-value to those abstractions. Science doesn't strictly speaking require the latter, although there may be substantial disagreement on to what extent science actually follows this "minimalist" approach.
It depends on just what is meant on "absolute"; if one interprets it as you have in the case of absolute truth, in the sense that the validity of a moral statement may be independent of beliefs about it (what's commonly called 'objective' in metaethics), then absolute moral laws can indeed exist. Note that absolute in this sense does not mean independent of culture and/or society, only that that law itself may to some extent depend on cultural factors other than beliefs about it. This may even be explicit in hypothetical (as opposed to categorical) systems of ethics.Bugsby wrote:Step 4: ABSOLUTE MORAL LAWS DO NOT EXIST! This is still a big debate in philosophy, in the field of metaethics.
Either you're using a sense of 'absolute' different from the one you gave above, or you've managed to disprove an enormous class of ethical systems, such as utilitarianism, which posits an absolute moral imperative. This particular example has the bonus in that it can be interpreted as a hypothetical system (which was one of Kant's objections to it), so it can be made immune to certain well-known Humean concerns.Bugsby wrote:I am writing a thesis on this very subject. Absolute moral laws do not exist. If I wanted, I could write for hours on this, but I'm not going to bore you.
Now. As to moral objectivism, I am firmly opposed to it. The definition that I have of objectivism is "a given moral statement can be true or false, and that truth or falsity would hold independently of our thoughts or feelings about it." For example, if we believe that rape is wrong, then "wrongness" is just a property of rape, and would be even if no one thought that rape was wrong.
It's important to distinguish this metaethical claim from other normative ethical claims. For example, you suggest that disproving objectivism would disprove utilitarianism, but this is not the case. It is consistent to believe both that the right thing to do is to maximize happiness (or whatever principle you might endorse) while believing that that particular moral belief is a function of one's psychology, not representative of any greater moral truth. I hold beliefs along roughly utilitarian lines. I just believe that my moral beliefs are not grounded in some universal truth about moral laws.
Of course, all normative ethical principles feel objectivist. That can be conceded easily. No groundwork on any ethical principle has ever concluded with "but that's just how I feel about it." A linguistic analysis of our use of moral terms will come down pretty conclusively on the side of ethical realism. But to quote J.L. Mackie, just because we use moral terms as if they are objectively true, that does not mean that they are.
My own problem with objectivist ethics is that there is no way to justify your moral beliefs without begging the question. Take the example that the author of our proof-of-God website offers: child molestation. Most people believe that child molestation is wrong. But let's say that I think it's right. How would you go about proving me wrong?
A few possibilities:
Appeal to some theory
If you are a utilitarian, and utilitarianism forbids child molestation, then child molestation is wrong. Thus, I am wrong. Here's the problem with this approach. Theories are usually supported by appeals to our intuitions about particular cases. So if we try to support our theory that molestation is wrong by appealing to the utilitarian theory, while at the same time supporting utilitarianism by appeals to our intuitions about cases, we have an infinite explanatory regress. Theories justifying intuitions justifying theories justifying intuitions justifying theories.... that doesn't work. We need explanatory priority somewhere. Theories must either be prior to our intuitions or vice versa.
1. Intuitions are prior to theories: You can't prove me wrong by appeals to a theory.
2. Theories are prior to intuitions: You are now in the situation where you need to justify your theory to me. Keep two things in mind. First, you cannot use non-normative premises. As Hume proved, no amount of descriptive premises can yield a normative conclusion. Second, you cannot use normative premises. This would almost certainly qualify as an appeal to moral intuition, and thus violates our basic "theories are prior to intuitions" method. I admit there MIGHT be a way here to justify a theory here, but I sure don't see it.
Appeals to some form of perfect observer
We could try to justify our intuitions by saying that they are similar to the intuitions of some perfect moral judge. Like Kant, we could be talking about a perfectly rational agent. Or a perfectly informed judge, or a perfectly sympathetic judge, or any number of other criteria. The problem is, none of us are perfect judges. So we can't ask anyone. We'd have to guess at what a perfect judge would think. So in effect, we would have to know what we would believe if we were smarter than we really are, or more "rational" than we really are, or what have you. These guesses are likely to be wrong. How do I know what I would know if I knew what I don't know? I don't.
Appeals to self-evidence.
"If you just understand all the facts of the case, you will just SEE that it is wrong to molest children. If you do not, there is no help for you; you are fundamentally misguided." That argument is very persuasive if you do believe that it is wrong to molest children. But if you don't it's not persuasive at all. Rather, it's a bit insulting. I could just as easily claim that YOU are the one who is fundamentally misguided. So we are back where we started.
These are a few of the objections I've explored and hopefully refuted. If anyone has any other methods of trying to justify moral beliefs, or if they find any flaws with the arguments I've presented against the methods of justification above, then post them here. I need criticism to get my arguments working as tightly as they can.
Note: This is a compression of a 15-page draft that I am expanding into a thesis. As such, 1) my ideas here are a lot less fully developed than I have them elsewhere, and 2) This is a work in progress, and will actually be the key part of my graduate school application to some highly selective programs. Keep that in mind. Ask me if you want to use these ideas outside the forum; seeing as how things can get pretty competitive in philosophy, I am a bit paranoid about protecting my ideas.
