Chad Meister: can atheists rationally ground morality?

Philosopher Chad Meister takes a look at the attempts of some prominent atheists to make rational sense of morality within their worldviews.

Here is the abstract:

Atheists often argue that they can make moral claims and live good moral lives without believing in God. Many theists agree, but the real issue is whether atheism can provide a justification for morality. A number of leading atheists currently writing on this issue are opposed to moral relativism, given its obvious and horrific ramifications, and have attempted to provide a justification for a nonrelative morality. Three such attempts are discussed in this article: Walter Sinnott-Armstrong’s position that objective morality simply “is”; Richard Dawkins’s position that morality is based on the selfish gene; and Michael Ruse and Edward Wilson’s position that morality is an evolutionary illusion. Each of these positions, it turns out, is problematic. Sinnott-Armstrong affirms an objective morality, but affirming something and justifying it are two very different matters. Dawkins spells out his selfish gene approach by including four fundamental criteria, but his approach has virtually nothing to do with morality—with real right and wrong, good and evil. Finally, Ruse and Wilson disagree with Dawkins and maintain that belief in morality is just an adaptation put in place by evolution to further our reproductive ends. On their view, morality is simply an illusion foisted on us by our genes to get us to cooperate and to advance the species. But have they considered the ramifications of such a view? Each of these positions fails to provide the justification necessary for a universal, objective morality—the kind of morality in which good and evil are clearly understood and delineated.

[…]We can get to the heart of the atheist’s dilemma with a graphic but true example. Some years ago serial killer Ted Bundy, who confessed to over thirty murders, was interviewed about his gruesome activities. Consider the frightening words to his victim as he describes them:

Then I learned that all moral judgments are “value judgments,” that all value judgments are subjective, and that none can be proved to be either “right” or “wrong”….I discovered that to become truly free, truly unfettered, I had to become truly uninhibited. And I quickly discovered that the greatest obstacle to my freedom, the greatest block and limitation to it, consists in the insupportable “value judgment” that I was bound to respect the rights of others. I asked myself, who were these “others”? Other human beings, with human rights? Why is it more wrong to kill a human animal than any other animal, a pig or a sheep or a steer? Is your life more to you than a hog’s life to a hog? Why should I be willing to sacrifice my pleasure more for the one than for the other? Surely, you would not, in this age of scientific enlightenment, declare that God or nature has marked some pleasures as “moral” or “good” and others as “immoral” or “bad”? In any case, let me assure you, my dear young lady, that there is absolutely no comparison between the pleasure I might take in eating ham and the pleasure I anticipate in raping and murdering you. That is the honest conclusion to which my education has led me—after the most conscientious examination of my spontaneous and uninhibited self.5

While I am in no way accusing atheists in general of being Ted Bundy-like, the question I have for the atheist is simply this: On what moral grounds can you provide a response to Bundy? The atheistic options are limited. If morality has nothing to do with God, as atheists suppose, what does it have to do with? One response the atheist could offer is moral relativism, either personal or cultural. The personal moral relativist affirms that morality is an individual matter; you decide for yourself what is morally right and wrong. But on this view, what could one say to Bundy? Not much, other than “I don’t like what you believe; it offends me how you brutalize women.” For the personal relativist, however, who really cares (other than you) that you are offended by someone else’s actions? On this view we each decide our own morality, and when my morality clashes with yours, there is no final arbiter other than perhaps that the stronger of us forces the other to agree. But this kind of Nietzschean “might makes right” ethic has horrific consequences, and one need only be reminded of the Nazi reign of terror to see it in full bloom. This is one reason why thoughtful atheists, such as Christopher Hitchens, Walter Sinnott-Armstrong, Richard Dawkins, Sam Harris, Daniel Dennett, and others don’t go there.6

But what about cultural moral relativism—the view that moral claims are the inventions of a given culture? Most thoughtful atheists don’t tread here either, and this is one reason why: If right and wrong are cultural inventions, then it would always be wrong for someone within that culture to speak out against them. If culture defines right and wrong, then who are you to challenge it? For example, to speak out against slavery in Great Britain in the seventeenth century would have been morally wrong, for it was culturally acceptable. But surely it was a morally good thing for William Wilberforce and others to strive against the prevailing currents of their time and place to abolish the slave trade. For the cultural moral relativist, all moral reformers—Wilberforce, Martin Luther King, Jr., even Jesus and Gandhi, to name a few—would be in the wrong. But who would agree with this conclusion? Thankfully, most leading atheists agree that moral relativism is doomed.7

So what do they affirm? Here are three accounts that recent atheists have defended: (1) objective morality simply “is,” (2) morality is based on the selfish gene, and (3) morality is an evolutionary illusion.8 Let’s take a brief look at each of them.

Will robots and machines ever have consciousness like humans?

There is a very famous thought experiment from UC Berkeley philosopher John Searle that all Christian apologists should know about. And now everyone who reads the Wall Street Journal knows about it, because of this article.

In that article, Searle is writing about the IBM computer that was programmed to play Jeopardy. Can a robot who wins on Jeopardy be “human”?Searle says no. And his famous Chinese room example (discussed in the article) explains why.

Excerpt:

Imagine that a person—me, for example—knows no Chinese and is locked in a room with boxes full of Chinese symbols and an instruction book written in English for manipulating the symbols. Unknown to me, the boxes are called “the database” and the instruction book is called “the program.” I am called “the computer.”

People outside the room pass in bunches of Chinese symbols that, unknown to me, are questions. I look up in the instruction book what I am supposed to do and I give back answers in Chinese symbols.

Suppose I get so good at shuffling the symbols and passing out the answers that my answers are indistinguishable from a native Chinese speaker’s. I give every indication of understanding the language despite the fact that I actually don’t understand a word of Chinese.

And if I do not, neither does any digital computer, because no computer, qua computer, has anything I do not have. It has stocks of symbols, rules for manipulating symbols, a system that allows it to rapidly transition from zeros to ones, and the ability to process inputs and outputs. That is it. There is nothing else.

Here is a link to the full article by John Searle on the Chinese room illustration.

By the way, Searle is a naturalist – not a theist, not a Christian. But he does oppose postmodernism. So he isn’t all bad. But let’s hear from a Christian scholar who can make more sense of this for us.

Here’s a related article on “strong AI” by Christian philosopher Jay Richards.

Excerpt:

Popular discussions of AI often suggest that if you keep increasing weak AI, at some point, you’ll get strong AI. That is, if you get enough computation, you’ll eventually get consciousness.

The reasoning goes something like this: There will be a moment at which a computer will be indistinguishable from a human intelligent agent in a blind test. At that point, we will have intelligent, conscious machines.

This does not follow. A computer may pass the Turing test, but that doesn’t mean that it will actually be a self-conscious, free agent.

The point seems obvious, but we can easily be beguiled by the way we speak of computers: We talk about computers learning, making mistakes, becoming more intelligent, and so forth. We need to remember that we are speaking metaphorically.

We can also be led astray by unexamined metaphysical assumptions. If we’re just computers made of meat, and we happened to become conscious at some point, what’s to stop computers from doing the same? That makes sense if you accept the premise—as many AI researchers do. If you don’t accept the premise, though, you don’t have to accept the conclusion.

In fact, there’s no good reason to assume that consciousness and agency emerge by accident at some threshold of speed and computational power in computers. We know by introspection that we are conscious, free beings—though we really don’t know how this works. So we naturally attribute consciousness to other humans. We also know generally what’s going on inside a computer, since we build them, and it has nothing to do with consciousness. It’s quite likely that consciousness is qualitatively different from the type of computation that we have developed in computers (as the “Chinese Room” argument, by philosopher John Searle, seems to show). Remember that, and you’ll suffer less anxiety as computers become more powerful.

Even if computer technology provides accelerating returns for the foreseeable future, it doesn’t follow that we’ll be replacing ourselves anytime soon. AI enthusiasts often make highly simplistic assumptions about human nature and biology. Rather than marveling at the ways in which computation illuminates our understanding of the microscopic biological world, many treat biological systems as nothing but clunky, soon-to-be-obsolete conglomerations of hardware and software. Fanciful speculations about uploading ourselves onto the Internet and transcending our biology rest on these simplistic assumptions. This is a common philosophical blind spot in the AI community, but it’s not a danger of AI research itself, which primarily involves programming and computers.

AI researchers often mix topics from different disciplines—biology, physics, computer science, robotics—and this causes critics to do the same. For instance, many critics worry that AI research leads inevitably to tampering with human nature. But different types of research raise different concerns. There are serious ethical questions when we’re dealing with human cloning and research that destroys human embryos. But AI research in itself does not raise these concerns. It normally involves computers, machines, and programming. While all technology raises ethical issues, we should be less worried about AI research—which has many benign applications—than research that treats human life as a means rather than an end.

When I am playing a game on the computer, I know exactly why what I am doing is fun – I am conscious of it. But the computer has no idea what I am doing. It is just matter in motion, acting on it’s programming and the inputs I supply to it. And that’s all computers will ever do. Trust me, this is my field. I have the BS and MS in computer science, and I have studied this area. AI has applications for machine learning and search problems, but consciousness is not on the radar. You can’t get there from here.

New study: patients experience awareness of surroundings after brain ceases to function

Reported in the left-wing UK Independent.

Excerpt:

There is scientific evidence to suggest that life can continue after death, according to the largest ever medical study carried out on the subject.

A team based in the UK has spent the last four years seeking out cardiac arrest patients to analyse their experiences, and found that almost 40 per cent of survivors described having some form of “awareness” at a time when they were declared clinically dead.

Experts currently believe that the brain shuts down within 20 to 30 seconds of the heart stopping beating – and that it is not possible to be aware of anything at all once that has happened.

But scientists in the new study said they heard compelling evidence that patients experienced real events for up to three minutes after this had happened – and could recall them accurately once they had been resuscitated.

Dr Sam Parnia, an assistant professor at the State University of New York and a former research fellow at the University of Southampton who led the research, said that he previously that patients who described near-death experiences were only relating hallucinatory events.

One man, however, gave a “very credible” account of what was going on while doctors and nurses tried to bring him back to life – and says that he felt he was observing his resuscitation from the corner of the room.

Speaking to The Telegraph about the evidence provided by a 57-year-old social worker Southampton, Dr Parnia said: “We know the brain can’t function when the heart has stopped beating.

“But in this case, conscious awareness appears to have continued for up to three minutes.

“The man described everything that had happened in the room, but importantly, he heard two bleeps from a machine that makes a noise at three minute intervals. So we could time how long the experienced lasted for.

“He seemed very credible and everything that he said had happened to him had actually happened.”

Dr Parnia’s study involved 2,060 patients from 15 hospitals in the UK, US and Austria, and has been published in the journal Resuscitation.

Of those who survived, 46 per cent experienced a broad range of mental recollections, nine per cent had experiences compatible with traditional definitions of a near-death experience and two per cent exhibited full awareness with explicit recall of “seeing” and “hearing” events – or out-of-body experiences.

Previously, I blogged about two very reliable examples of near-death experiences, as well as peer-reviewed published work done by UCLA professor Jeffrey Schwartz on “mental effort”. Not to mention philosophical arguments for non-physical minds.

How should we use this evidence? Well, I wouldn’t use it as part of a case for theism, but I think it is useful to show that materialism is clearly false. And that’s before we even get to the cosmological and fine-tuning arguments, which make it even more clear that materialism is false.
