To be clear I would like to offer these definitions of objective and absolute.
objective:
1) not influenced by personal feelings, interpretations, or prejudice; based on facts; unbiased: an objective opinion.
2) intent upon or dealing with things external to the mind rather than with thoughts or feelings
3) of or pertaining to something that can be known; existing independent of thought or an observer as part of reality.
Philosophically speaking, and as I am using it in my comments, "objective" is what is described in points 2 and 3 of your definitions above.
absolute:
free from imperfection; complete; perfect:
This is not a term I used, so I don't understand why you are defining it here...WHat's more, I would not use the term "absolute" strictly in the way you define it above. Certainly, in relation to the Moral Argument, "absolute" is better defined as,
...not dependent on, conditioned by, or relative to anything else; independent...
I see no evidence, nor do I think any can be presented, that demonstrates the existence of either objective or absolute moral precepts or duties. For example, if all humans were to disappear from existence, morality as a concept would disappear, as it is a human construct not create by God.
"Objective," at least in the sense in which I am using it, means "mind-independent," which means that objective morality exists independently of the human mind. If this is so, then objective morality is not contingent upon human beings; it exists even if humans do not.
Your argument above begs the question, too. You assume God does not exist and, therefore, objective morality is a human construct. But you have offered no good reason why your initial assumption (that God does not exist) should be accepted.
Furthermore if morality is a creation of, or an extension of God and God's nature, then it would necessarily be perfect; I see no examples of perfect moral precepts.
But what do you mean by "example"? If you mean you see no one living out God's moral precepts perfectly, then I would point you to Christ whose perfect example all Christian believers are commanded to emulate. If you mean God's laws themselves I would like to know which of His moral laws (not those laws of separation peculiar to the Israelites, or commands of war issued to them under theocratic rule) are imperfect?
I think your argument disingenuously ignores that objective morality from a Divine Moral Law Giver would necessarily be demonstrably absolute.
As I noted above, the term "absolute" has a broader usage than your definition provides. I am not willing to confine its meaning to the single definition you wish to use.
Now, regarding the first definition of objective, I do believe that an unbiased, and factually based system of morality can be constructed but claim it can be absolute because I do not believe that morality is static; it evolves as a societies needs and values change.
"Objective" entails a certain degree of static-ness. Philosophically, an objective characteristic is one that follows its object around. A hard, grey, rough rock is so whether it is buried under a thousand feet of dirt or sitting on a pedestal in a museum. Its characteristics of hardness, greyness, and roughness follow the rock around and so these characteristics are said to be objective to the rock. In the same way, objective moral values and duties do not alter with time and place. In order to be truly objective they must not. So, when you speak of a morality that is fluid, that changes with the times, you are not speaking of a truly objective morality.
Once again, I see no evidence of an "innate objective morality" in human beings.
I do. Very clearly. For example, would you torture a baby for fun? Has there ever been a circumstance in which doing so was considered a moral duty? If not, I think we have at least one genuinely-objective moral duty: one ought never to torture a baby for fun. How about murder? Would you like to be murdered? Would anybody? Has there ever been a time or place where everybody agreed that murdering was a moral duty? I'm not talking capital punishment or killing the enemy on the battlefield, here. I mean someone coming up to you and stabbing you in the heart for no apparent reason. If not, then we have another objective moral duty: You shall not murder. And so on.
There are near universal condemnations of certain actions, but they are not objective/absolute.
I disagree. I think they are precisely what you say they are not.
These near-universals are products of our evolution as social animals.
Saying so doesn't make it so. Proof, please.
One sure way to be ostracized or expelled from a group is to unjustly murder a member of that group. Our ancestors evolved in small groups for millions of years, and modern humans lived in these small groups for hundreds of thousands of years, and survival and reproduction crucially depended upon acceptance. Our brains evolved in these environments and developed "strategies" in which to further and refine the success in our social behavior.
This is just one of the many "just-so" stories evolutionists are so fond of. Plausibility is not probability.
Also, on the view you sketch out above there is no basis for claiming that morality is objectively true and thus authoritative and binding. Evolution has created a sort of herd morality for humans that is essentially the same in purpose as the "morality" that governs, say, baboons. Neither morality is superior to the other, only different.
It is difficult to argue that the immorality of murder is an objective (Def. 1 & 2) or absolute (perfect) precept.
Oh? I don't think so. Just ask anyone of they would like to be murdered.
The Christian God as Moral Law Giver may condemn murder, but the both the bible and Christianity have long histories of murder.
You appear here to be guilty of the "Is-Ought Fallacy." Do you assume that because a story in the local newspaper recounts a murder that it is therefore approving of murder or commanding the reader to murder? Of course not. This is true of the Bible, too.
If "Christians" have murdered, they have done so in contradiction to the moral precepts of their faith. Such conduct, then, cannot be said to be characteristic of the faith.
A best way to attempt a summation of all of this work is Harris' description:
"moral actions increase the well-being of conscious creatures"
This is a descriptive statement, not a prescriptive one. WHose well-being do we mean? How is well-being defined?
Why is increasing the well-being of others a morally-imperative thing? Why should a person not seek to maximize their own well-being even if doing so diminishes the well-being of others?
I can readily admit that the rather unappealing crux of morality without God is genetic determinism and moral relativism. However, the "naturalistic fallacy" (is-ought) is to relent to the idea that freewill and objectivity morality necessarily cannot exist.
Yes, this is the inevitable problem with a naturalistic basis for morality.
My views cannot be boxed in so easily, I believe that freewill can exist, but requires effort and while morality is relative, an objective standard can be constructed. I can elaborate in further posts, but it really takes a lot of time and space to pull together the research of several disciplines and philosophies into one coherent post. I am aware of most critiques to these ideas so I would be happy to respond as they are brought up further.
Well, you have offered no specifics here, so it is impossible to comment on your views.
Scientific facts about the brain and thus the mind, have already given support to many EP theories; as more research occurs, an even clearer understanding of human nature and morality will emerge, and with it the conversation about morality can move out of the Bronze Age and into the 21st century.
There is some very sophisticated thinking that has gone on regarding Mind-Body Dualism. I have not seen that merely showing that the brain and mind are linked makes them identical any more than showing that a motor produces energy makes the motor and the energy it produces identical.
