…integrating Christian faith and knowledge in the public square

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.

Brian Auten interviews Dr. Angus Menuge on philosophy of mind

Click here for the interview. It’s up at Apologetics 315!

Details:

Today’s interview is with Dr. Angus Menuge, Professor of Philosophy  at Concordia University, and author of Agents Under Fire: Materialism and the Rationality of Science. He talks about his background and work, the philosophy of mind, what reason (or reasoning) is, what materialism is as a worldview, things excluded from a materialistic worldview, methodological naturalism and materialism, accounting for free will, materialistic accounts of reason, the epistemological argument from reason, the ontological argument from reason, finding the best explanation for reason, problems with methodological naturalism, implications of materialism, practical application of the argument from reason, advice for apologists, the International Academy of Apologetics, and more.

If what Dr. Menuge says in this interview is true, and I think it is, then a person who believes in materialism can neither ground free will nor rationality! So atheism wouldn’t really be freethought so much as it would be… un-free… non-thought.

In case people don’t want to listen to the podcast, then I’ve got some things for you to read below.

The ontological argument from reason

Dr. Menuge presented a paper at the real Evangelical Philosophical Society conference for students and professors of philosophy, and you can download the paper here in Word format. (here’s a PDF version I made)

Here is the introduction to the paper that Dr. Menuge read at the EPS conference:

The argument from reason is really a family of arguments to show that reasoning is incompatible with naturalism. Here, naturalism is understood as the idea that foundationally, there are only physical objects, properties and relations, and anything else reduces to, supervenes on, or emerges from that. For our purposes, one of the most important claims of naturalism is that all causation is passive, automatic, event causation (an earthquake automatically causes a tidal wave; the tidal wave responds passively): there are no agent causes, where something does not happen automatically but only because the agent exerts his active power by choosing to do it. The most famous version of the argument from reason is epistemological: if naturalism were true, we could not be justified in believing it. Today, I want to focus on the ontological argument from reason, which asserts that there cannot be reasoning in a naturalistic world, because reasoning requires libertarian free will, and this in turn requires a unified, enduring self with active power.

The two most promising ways out of this argument are: (1) Compatibilism—even in a deterministic, naturalistic world, humans are capable of free acts of reason if their minds are responsive to rational causes; (2) Libertarian Naturalism—a self with libertarian free will emerges from the brain. I argue that neither of these moves works, and so, unless someone has a better idea, the ontological argument from reason stands.

The paper is 11 pages long, and it is helpful for those of you looking for some good discussion of one of the issues in the area of philosophy of mind.

You may also be interested in Alvin Plantinga’s epistemological argument from reason, which is related to this argument. It shows that even to have the ability to think, you have to have a certain anthropology and you have to have mental faculties that are designed for reason, not survival.

Methodological naturalism

Dr. Menuge also wrote an article entitled “Is methodological materialism good for science?”.

Intro:

Should science by governed by methodological materialism? That is, should scientists assume that only undirected causes can figure in their theories and explanations? If the answer to these questions is yes, then there can be no such thing as teleological science or intelligent design. But is methodological materialism a defensible approach to science, or might it prevent scientists from discovering important truths about the natural world? In my contribution to The Waning of Materialism (Oxford University Press, 2010), edited by Robert Koons and George Bealer, I consider twelve of the most common arguments in favor of methodological materialism and show that none of them is convincing.

Of these arguments, perhaps the most prevalent is the “God of the gaps” charge, according to which invoking something other than a material cause is an argument from ignorance which, like a bad script writer, cites a deus ex machina to save our account from difficulty. Not only materialists, but also many Christian thinkers, like Francis Collins, worry that appeal to intelligent design commits the God of the gaps fallacy.

As I argue, however, not only is an inference to an intelligent cause not the same as an inference to the supernatural, it is a mistake to assume that all gap arguments are bad, or that only theists make them. If a gap argument is based solely on ignorance of what might explain some phenomenon, then indeed it is a bad argument. But there are many good gap arguments which are made both by scientific materialists and proponents of intelligent design.

So how do you make an argument like that?

As Stephen Meyer has argued in his Signature in the Cell, intelligent design argues in just the same way, claiming not merely that the material categories of chance and necessity (singly or in combination) are unable to explain the complex specified information in DNA, but also that in our experience, intelligent agents are the only known causes of such information. The argument is based on what we know about causal powers, not on what we do not know about them.

Since the inference is based on known causal powers, we learn that the cause is intelligent, but only further assumptions or data can tell us whether that intelligence is immanent in nature or supernatural. It is a serious mistake to confuse intelligent design with theistic science, and the argument that since some proponents of design believe that the designer is God, that is what they are claiming can be inferred from the data, is a sophomoric intensional fallacy.

If you think this is interesting, then do have a listen to the podcast. Dr. Menuge is not an ordinary academic – he is very direct. He calls materialism “a catastrophe” in the podcast!

Pastor Matt: What happens when you die?

This post is from Pastor Matt’s blog.

Excerpt:

Michael Bird breaks it all down as follows:

1. Prior to Christ’s ascension, all who died descended to Sheol/Hades, which was divided into two parts, one for the wicked and one for the righteous.

2. At Christ’s ascension, he went into heaven and took with him all of the saints in the paradisal part of Sheol/Hades, while the wicked remain in Sheol/Hades, waiting for judgment.

3. Upon death new covenant believers go to be with Christ in heaven ahead of the general resurrection, while the wicked descend to Sheol/Hades waiting for judgment.

4. Eventually Sheol/Hades will be thrown into hell and all believers will share in the new heavens and new earth.

See Evangelical Theology p. 323.

I’ve featured some debates with Michael Bird before, he is a famous evangelical historian.

It’s important to understand that the Christian view of humans is that we have a material part and a non-material part. When you die, the material part goes into a tomb. The non-material part goes on to be with God, until the day when you get a new resurrection body.

Earlier, I blogged about some philosophical arguments for the existence of souls and some scientific evidence for the existence of souls, and it’s worth looking over in order to move beyond mere opinions. Like it or not, this is the way we are! Not just bodies, but souls.

What does the concept of resurrection mean to Jewish theologians?

Here’s a helpful post from Eric Chabot talks about this and other interesting topics related to the resurrection.

Excerpt:

Where do we see resurrection in the Hebrew Bible?

As just stated, belief in a resurrection of persons from the dead are seen in eight passages: (Job 19:26; Ps. 17:15; 49:15; 73:24; Is. 26:19; 53:10; Dn. 12:2;12:13). The resurrection terminology is seen in two places (Ezek. 37:1-14; Hos. 6:2) to show a national and spiritual restoration brought about by the return from the exile. As far as the nature of the future bodily resurrection, it may involve a corpse or the receipt of a material body comparable to the present physical body (Job 19:26; Is. 26:19), or it may be a matter of transformation (Dn. 12:2-3 and perhaps 12:13); or glorification after reanimation, in the case of the righteous.

As far as the function of the resurrection, it may be personal vindication (Is. 26:16; 53:10-12). Resurrection may also have a function in relation to reward or punishment (Dn. 12:2; 12:13), an assumption to heaven and enriched fellowship with God (Ps. 49:15; 73:24,26), or preface to the beatific vision of God (Ps. 17:15 and possibly Job 19:26). (1)

The Greek word for resurrection is “anatasis” which means “a raising up” or “rising.” There are resuscitations in the Tanakh such as the example of Elijah and Elisha raising a person from death (1 Kings 17-23; 2 Kings 4:34-35). While these figures may have been raised in a resurrection sense, they were not raised immortal in the same way Jesus was.

Extra-Biblical Passages on Resurrection

There are also extra-biblical passages that speak about the resurrection (Enoch 92:2; 4 Ezra 7:32; Enoch 91:10; 2 Maccabees 7:9; 14; 28-29). Even the The Messiah Apocalypse, which is dated between 100 and 80 B.C.E mentions resurrection: “He [God] frees the captives, makes the blind see, and makes the bent over stand straight…for he will heal the sick, revive the dead, and give good news to the humble and the poor he will satisfy, the abandoned he will lead, and the hungry he will make rich.” (2)

In the Rabbinical literature there are explicit teachings on the resurrection. It says in the Mishnah 10.1, it says, “All Israelites have a share in the world to come; … and these are they that have no share in the world to come: he that says that there is no resurrection of the dead prescribed in the Law.” Moses Maimonides, a Jewish rabbi and a medieval Jewish philosopher who has forever influenced the Jewish and non-Jewish world said:

” The resurrection of the dead is one of the cardinal principles established by Moses our teacher. A person who does not believe this principle has no real religion, certainly not Judaism. However, resurrection is for the righteous. This is the earning of the statement in Breshit Rabbah, which declares: “the creative power of rain is both for the righteous and the wicked, but the resurrection of the dead is only for the righteous.” Our sages taught the wicked are called dead even when they are still alive; the righteous are alive even when they are dead” (Bab. Talmud Brakhot 18 b).

3 points are made here: 1. Resurrection is a cardinal principle taught in the Torah which all Jews must believe 2. It is for the righteous alone 3. All men must die and their bodies decompose. (3)

It’s important to understand that the concept of resurrection had a meaning before Christianity ever started. And it’s interesting to ask why the early Christians applied the notion of resurrection to Jesus. What is the best explanation for their decision to do such a strange thing? Why not just give up on him and deny that he was the Messiah when he was killed by the Romans?
