A person does not have to believe in God to have absurd and irrational beliefs that bypass reason.
One of the beliefs relevant here is the belief that evidence of altruism in animals helps to prove that morality does not come from God. In fact, it is quite easy to demonstrate that proof of altruism in animals has nothing to do with morality.
This discussion is being prompted by an article in Wired magazine on a scientific study in which Rats Free Trapped Friends, Hint at Universal Empathy.
This is a study of two rats in a cage. One is free to move around the cage, while the other is in a very confined space. In this research, the free rat (relatively speaking) routinely releases the confined rat - allegedly for no reason other than an act of kindness.
The article itself doesn't mention morality. The error I am pointing to does not appear in the article. It appears in blog posts and comments about the article in which authors point to the article as proof that Christians are wrong about the possibility of morality without God.
Those blog posts and comments are written by people demonstrating such an eagerness to embrace a "Christians are wrong" conclusion that they utterly blind themselves to reason in order to reach that conclusion. In this, their behavior is much like those who abandon reason to reach the conclusion that the Earth is less than 10,000 years old or that the story of Noah and the flood is literally true.
I am going to ask those people to pause for a moment and think. Here are some questions to answer.
Question 1: What makes altruism moral?
Maybe altruism is evil?
You cannot make the leap from, "X shows altruism" to "X shows morality" until you can make the leap from altruism to morality. So, how do you cover that ground? How do you leap the chasm from "mice behave altruistically" to "mice do that which they morally ought to do"?
Does the free rat have a moral obligation to free the confined rat? Does the confined rat have a right to be free? Do these applications of moral concepts even make sense?
Question 2: What is the moral quality of predatory and parasitic behavior?
Evolution may have created altruistic rats - at least in these circumstances. However, evolution also created predators and parasites.
Evolution created a situation where, when a pair of male lions takes over a pride, they will kill the offspring of the previous lions. Is this moral or immoral? Or do moral concepts not apply?
What about the lion killing the antelope for food - a rather bloody and pain-inducing activity on the part of the lion. Is it lion acting immorally, or virtuously? Or, again, is it simply the case that we cannot apply moral terms to this behavior? If it is the latter, then why are we attaching moral terms to the altruism demonstrated above?
A wasp lays its eggs inside the living and paralyzed body of a spider. Moral or immoral? Or neither?
A bird lays its eggs in the nest of another bird that will then raise this chick as its own. Is this a morally impermissible act of exploitation? Does it make sense to apply moral terms?
What about taking the eggs of a bird and eating them. Is that immoral?
Demonstrating that certain behavior can be found in nature is not enough to show that we have discovered some natural morality. What we need is a way of demonstrating that the classification itself as moral, immoral, or neither can be found in nature. None of that is demonstrated by these experiments.
Question 3: So, are you telling me that, because we have this innate altruism, that evil is not possible?
Are you saying that I don't have to worry about people raping me or those that I care about, taking my property, practicing slavery, showing passive indifference to those in desperate need, lying, cheating, breaking promises, taking advantage of the elderly, engaging in assaults or bullying, about brutal dictatorships and blood-thirsty warlords and the like because innate altruism simply will not allow this type of behavior?
Of course it would be foolish to make that claim, given that we are surrounded by these evils.
However, when Christians express a concern that atheism undermines morality, these are the evils they are concerned with. They are afraid that, without religion, that the evils that humans are very much capable of performing will become a lot more common. Pointing to a pair of altruistic facts does nothing to counter this concern. The Christian only needs to point to the history book. While we can show that religion has been the source and justification of many of these evils and has often done nothing to prevent them, altruistic rats does not prove that they will become less common without religion.
Christians concerned with atheism undermining morality look at this research into altruistic mice and the so-called moral proofs that atheists draw from it and say, "Are you frikken serious? I know atheists are stupid, but you really do not need to these extremes to prove it."
Question 4: Are you saying that the mouse who frees the confined companion deserves praise and the one who doesn't deserves condemnation?
Morality is about praise and condemnation. It is about deserving rewards or punishment. That rape is wrong justifies inflicting harm on rapists, not only as a way of deterring rape but because the rapist deserves to be punished.
You can hardly draw a valid inference from, "I have a genetic disposition to want to kill people like you; therefore, you DESERVE to die." Or "I am genetically disposed to free you from that confined place. Therefore, I deserve praise for releasing you."
These experiments involving altruistic rats tell us nothing about who DESERVES to be punished or rewarded. In fact, the very idea of praising people or condemning them on the basis of their DNA is nonsensical.
Question 5: How are you going to use this type of research to answer moral questions?
What particular DNA sequence are we looking for as proof that homosexual behavior is permissible and child rape is not? What strand of DNA do we read to discover whether, and to what degree, the rich are to be taxed or whether we should execute murderers? Moral philosophers trying to answer questions about our obligations to the environment should look at which chromosome?
The purpose of these questions are to point out the fact that these particular biological premises are not even relevant to trying to answer moral questions.
As it turns out, moral questions concern a different subject matter entirely. Specifically, they do not concern innate biological dispositions. They concern the dispositions that we ought or ought not to learn.
I want to repeat that last point because it actually applies to this whole post. Moral questions are questions about the dispositions we ought or ought not to learn, and about teaching those dispositions to each generation through the use of social tools such as praise, condemnation, reward, and punishment. It is not about the things we do as a matter of biological necessity.
In addition, this line of questions demonstrates that atheists are just as adept at theists at abandoning reason and rushing to give a firm bear hug to conclusions that they like. This disposition is not a religious problem. It is a human problem. In this case, it results in atheists making claims and drawing inferences that are as absurd as anything you can get from religion.
Evidence of genetic or evolved altruism may be interesting. It may be good science and worthy of our attention and study. However, it does not prove that learned morality is effective or even possible without religious belief. It does not answer the question that theists are concerned with - and that we all have reason to concern with.
The moral questions are: What is the difference between good and evil? How do we know? And how do we cause people to perform those goods and refrain from committing those evils they are obviously capable of committing.
