Philosophy and science

An interesting example of the different ways that scientists and ‘pure’ philosophers view things arose in an exchange I had in the comments of a previous post.

Commenter Kenneth brought up an interesting argument that I had not heard before for the existence of the afterlife, an argument that he said had originally been proposed by the philosopher Spinoza (1632-1677). Basically the argument boiled down to the assumption that each one of us is simply a collection of atoms arranged in a particular way. When a person (A) dies, those atoms are dispersed and join the universe of atoms that percolate through space and time. But there is always the possibility that, purely by chance as a result of random motion, a set of atoms will arrange themselves in exactly the same arrangement that made up A when A was still alive. So thus A will have been ‘reborn.’ Kenneth argues that thus the existence of life after death has been established, at least in principle.

The nature of the argument can be perhaps understood better with a simpler example of thoroughly mixing ink and water in a glass and then leaving it alone to sit undisturbed. We would think that this mixing is an irreversible process and that separation into water and ink again would not be possible except as a result of extraordinary efforts by external agents. But in fact if you simply wait long enough, there is a very remote possibility that the random motion of the individual ink and water molecules will result in a momentary spontaneous separation of the mixture in the container into two separate regions, one of pure water and the other of purely ink molecules (whatever ink molecules are).

Since all that this argument requires is the ability to wait for a very long time for which these unlikely events to occur, Kenneth has satisfied himself, from a philosophical point of view, that Spinoza’s argument is valid. And that once we concede the possibility that someone’s atoms can be reconstituted in its original form, the existence of life after death has been established, at least in principle

But science does not limit itself to these ‘in principle’ arguments. Such arguments are just the first steps. Science is always looking at the detailed consequences of such ideas in order to translate them into research programs. And this is where Spinoza’s argument for the possibility of an afterlife breaks down.

For one thing, the human body is not just an arrangement of atoms, like that of molecules in a mixture of ink and water, or the oxygen and nitrogen molecules in a container of air. The atoms in the human body are bound together in complex organic molecules, which are in turn held together by other forces to form cells and tissues and so on. It is not enough to just bring the atoms together, you also have to create the chemical reactions that fuse them into these molecules, and this requires energy from the outside used in a very directed way.

It is like frying an egg in a pan. Just breaking an egg into a skillet and leaving it there will not result in a fried egg, however long you wait, unless there is a source of energy to drive the reaction forward. A fried egg is not just a rearrangement of the atoms in a raw egg. It is one in which new compounds have been created and the creation of these compounds is a non-random process.

In addition, the probability of all the atoms that make up your body randomly arriving at the same locations that they occupied when you were alive is microscopically small. This is not a source of concern to Kenneth because all he needs is that this probability not be zero in order to satisfy his ‘in principle’ condition. But there is an inverse relationship between the probability of an event and the likely time that you would have to wait for the event to occur. For example, if you repeatedly throw a die, you would have to wait longer to get a six than to get just any even number because the probability of the former is less than that of the latter.

In the case of the body’s atoms coming together again, the probability is so small that the expected time for it to occur would be incredibly long. Again, it would not matter if this were a philosopher’s ‘in principle’ argument. But those arguments tacitly assume that nothing else is changing in the environment and that we have an infinite amount of time in the world to wait for things to occur.

But in reality events are never in isolation and science is always concerned about the interconnectedness of things. And this is where the ‘in principle’ argument breaks down. We know that the lifetime of the Sun is about ten billion years and that it will then become a huge ‘red giant’ that will grow enormously and even envelop the Earth. And later still, all the energy producing nuclear reactions in the stars will end, resulting in the heat death of the universe. So there will not be any surplus energy around, even in principle, to drive the chemical reactions to reconstitute the body’s molecules, even if they did manage to arrive randomly in exactly the right positions.

I think that this is where scientific research and philosophical speculations diverge. A scientist is not interested in just ‘in principle’ arguments for the afterlife of the kind that Kenneth says Spinoza makes. To be become interesting to scientists, Kenneth will have to provide at least numerical estimates of the probability the body’s atoms reconstituting themselves, and then use that probability to estimate the expected time for such an event to occur.

If that time is more than the expected heat death of the universe, then the question becomes moot. If it is less, then the scientist will ask if there is enough free energy at that time to drive the reaction forward and what is the probability that this energy will spontaneously be directed at the atoms in just the right amounts and directions to recreate the human body.

All these considerations, when brought together, suggest that Spinoza’s argument fails and that life after death as proposed by him is not going to ever happen.

That is the kind of difference between the approaches of pure philosophy and science.

Respect for religion-5: Are the new atheists practicing bad politics?

There is no doubt that atheists are becoming more outspoken these days and this has led to people asking why these ‘new atheists’ are now so ‘militant’. I do not think ‘militant’ is quite the right word. What has happened is that atheists are undergoing a change of attitude about what is and is not considered respect for religion.

It used to be that when it came to discussions about religion, a different standard applied than to discussions about (say) politics. With the latter, you could come right out and say that someone was wrong, and that was not considered disrespectful. But with religion, that was not the case. It was considered bad form to say that god and the afterlife did not exist and that those beliefs had no basis.

What atheists and others were supposed to do when god came up was to just be quiet and not challenge religious beliefs or statements of faith. But it was never clear why this has to be the rules of the discourse. After all, if someone claimed that they believed in the fairies dancing in their garden, we are not obliged to ‘respect’ that belief by not challenging it. At the very least we might ask for evidence or say something like “Really? How interesting. What makes you believe that?” So when someone says that they believe in god, why should we not respond the same way? But if we did so, they would likely be insulted because religious beliefs are supposed to be either self-evidently true or exempt from the rules of evidence or the bar for evidence is set so low that anything goes (“I know god exists because I feel his presence when I pray.”).

The new atheists are having none of this old-fashioned notion of what constitutes respect for religion. The most that ‘respect’ can command is that we do not treat religious believers as being crazy because it is undoubtedly true that people who are perfectly rational about almost everything can have irrational beliefs in compartmentalized areas of their lives.

Respect cannot, and should not, be extended to discouraging the challenging religious beliefs. What the new ‘new atheists’ are doing is expressing their skepticism about religion directly, publicly, and sometimes in a spirit of mischievous humor.

The Blasphemy Challenge, where individuals post video clips of themselves cheerfully denying the Holy Spirit, are direct challenges to the fundamental beliefs of Christianity. The trigger for this challenge is the passage in the Bible (Mark 3:28-29) where Jesus draws a very clear line in the sand and says: “I tell you the truth, all the sins and blasphemies of men will be forgiven them. But whoever blasphemes against the Holy Spirit will never be forgiven; he is guilty of an eternal sin.” In other words, this particular sin, blasphemy against the Holy Spirit, is the ultimate no-no, the sin that cannot be forgiven, ever. What the people behind the site say is that passages like this are meant to frighten people into believing in god, and the ‘respect for religion’ trope is being used to prevent people from pointing this out.

In the past, atheists would have simply ignored things like this. If you don’t believe in a god, why would you care if you were condemned by this non-existent god? But now, there are hundreds of them going online, publicly risking damnation by making jokes about the Holy Spirit. They are not calling religious people names or things like that. They are simply and publicly saying what they don’t believe.

This new atheism has ruffled quite a lot of feathers in a religious establishment that has got accustomed to having their pieties accepted unquestioningly. The Rational Response Squad, which is behind the Blasphemy Challenge, was even profiled on Nightline. In the interview, it is interesting how often the idea of ‘lack of respect’ comes up in the words of religious believers and the interviewer. But all the atheists are saying is that there is no evidence for god and they are not afraid of hell because there is no evidence that it exists either. The language of the atheists is scientific while the religious people appeal to faith and mystery and fear of hell.

Once again, it is perhaps the existence of the internet that has been the galvanizing force in this new movement. Formerly atheists were isolated. But now they are realizing that there are many, many more of them out there than they thought, and they are joining up with others, and discovering that being an atheist, far from being a lonely experience, is a lot of fun. That has to be a good feeling.

There is a political price to be paid for speaking out this way. Some religious people are using the well-known public dislike for atheism to cast doubt on science by implying that science and atheism are joined at the hip and to argue that modern science demands atheism. Richard Dawkins says that he is sometimes told even by people who agree with his views that he is helping the forces of religious fundamentalism by enabling them to portray all scientists as atheists and that hence science itself is atheistic.

This has happened to me too. As some readers know, I was on Ohio’s Science Standards Advisory Board. During the struggle to keep intelligent design creationism (IDC) out of the standards, I was told that my public atheism was actually being used by some IDC advocates on the board to argue that evolution was atheistic and thus bad. It was gently suggested that I be more discreet about my atheism. I think that what some ‘moderates’ fear is that people’s attachment to religion is so strong that if asked to choose between god or no god, and if science is identified with no-god, , they will choose god and thus science will be rejected, and the religious moderates will end up allied with the fundamentalist and extremists.

This really is the fundamental political question.

I think that the best political alliances are those formed around specific issues, not on the basis of compatible ideologies or even people. For example, in the movement that opposes the Iraq war, there are many factions, ranging all over the political and religious spectrum, who are unlikely to agree on other issues. And that is fine. Coalitions should form because they advocate similar policies on a particular issue.

The same thing arises with social issues like poverty and health care. The alliances for each will again be formed on the basis of agreement over specific policy proposals. When forming such alliances, each person and group will stay true to their own principles but come together on strategy and tactics to achieve a certain result.

For example, I work with and support a religious group, the InterReligious Task Force in Cleveland which does excellent work on highlighting issues of injustice in Central and South America. They began their work in response to the brutal rape and murder of four Catholic nuns by the US-supported dictatorship in El Salvador in 1980, and their motivation arises from the feeling that their religion calls upon them to fight for justice. I respect that. My motivation is different from theirs but we agree on the goal of justice for the people of that region and that is sufficient for joint action.

The same should apply to the science-religion question. I think that there is nothing wrong with the new atheists pointing out that the beliefs of even mainstream religions are not rational, but still joining with them to oppose the teaching of IDC as science. Presumably mainstream religions are opposed to teaching IDC in science classes because they think it is a bad policy. Thus they should be willing to work together with anyone, including atheists, on this issue even though the new atheists seek that ultimate end of religious beliefs altogether. This kind of disagreement does not have to be a barrier to working together on those things on which they agree.

I do not think there is really a problem here, except for a shallow understanding of the nature of coalition politics. The problem, if at all, is that people get offended because they are mixing the public with the personal. If someone disagrees with them because of their views on topic A, they are personally offended and will not work with them on topic B, even if they agree with them.

Respect for religion-4: Religion as Conversation-stopper

I have written in the past about how religion should be kept in the private sphere and out of the public sphere. I have since discovered that philosopher Richard Rorty wrote an interesting essay with the above title on this topic in 1994, that was published in his book Philosophy and Social Hope (1999). In the essay, Rorty challenges Stephen Carter who wrote a book The Culture of Disbelief: How American Law and Politics Trivialize Religious Devotion. (Thanks to Michael Berube for bringing Rorty’s essay to my attention.)

Rorty says:

Carter puts in question what, to atheists like me, seems the happy, Jeffersonian compromise that the Enlightenment reached with the religious. This compromise consists in privatizing religion — keeping it out of what Carter calls “the public square,” making it seem bad taste to bring religion into discussions of public policy.
. . .
We atheists, doing our best to enforce Jefferson’s compromise, think it bad enough that we cannot run for public office without being disingenuous about our disbelief in God; despite the compromise, no uncloseted atheist is likely to get elected anywhere in the country. We also resent the suggestion that you have to be religious to have a conscience — a suggestion implicit in the fact that only religious conscientious objectors to military service go unpunished. Such facts suggest to us that the claims of religion need, if anything, to be pushed back still further, and that religious believers have no business asking for more public respect than they now receive.

Rorty adds:

Contemporary liberal philosophers think that we shall not be able to keep a democratic political community going unless the religious believers remain willing to trade privatization for a guarantee of religious liberty.
. .
The main reason religion needs to be privatized is that, in political discussion with those outside the relevant religious community, it is a conversation-stopper. Carter is right when he says:

One good way to end a conversation — or to start an argument — is to tell a group of well-educated professionals that you hold a political position (preferably a controversial one, such as being against abortion or pornography) because it is required by your understanding of God’s will.

Saying this is far more likely to end a conversation that to start an argument. The same goes for telling the group, “I would never have an abortion” or, “Reading pornography is about the only pleasure I get out of life these days.” In these examples, as in Carter’s, the ensuing silence masks the group’s inclination to say, “So what? We weren’t discussing your private life; we were discussing public policy. Don’t bother us with matters that are not our concern.”

This would be my own inclination in such a situation. Carter clearly thinks such a reaction inappropriate, but it is hard to figure out what he thinks would be an appropriate response by nonreligious interlocutors to the claim that abortion is required (or forbidden) by the will of God. He does not think it is good enough to say: OK, but since I don’t think there is such a thing as the will of God, and since I doubt that we’ll get anywhere arguing theism vs. atheism, let’s see if we have some shared premises on the basis of which to continue an argument about abortion. He thinks such a reply would be condescending and trivializing. But are we atheist interlocutors supposed to try to keep the conversation going by saying, “Gee! I’m impressed. You have a really deep, sincere faith”? Suppose we try that. What happens then? What can either party do for an encore?

Rorty captures exactly the problems raised by the ‘respect for religion’ trope. Not only does the introduction of religious ideas not advance public policy discussions, it actually hinders them by introducing a non-evidence based, non-negotiable belief and thus stops the conversation dead in its tracks.

Rorty makes the excellent point that putting religion into the private sphere is the only way that can guarantee religious freedom. Once religion gets a toehold into the public sphere, it increasingly becomes dominated by a narrower and narrower range of views that seeks to exclude all but the true believers. So all those who worry about having freedom of religion should be working to keep it out of the public sphere.

What we should be doing instead is trying, along the lines suggested by John Rawls in his book A Theory of Justice, to find what moral premises we all have in common despite our differing personal backgrounds and belief structures.

Religious people might complain, in the words of Carter, that they are being forced ‘to restructure their arguments in purely secular terms before they can be presented’ in the public sphere and suggests that this is somehow unfair to them. Rorty replies that all that this requires is dropping references to the premises of the arguments (i.e., not saying things like “But that violates what it says in the Book of Leviticus….”) when discussing public policy, and that “this omission seems like a reasonable price to pay for religious liberty.” He goes on that this requirement “is no harsher, and no more a demand for self-destruction, than the requirement that we atheists, when we present our arguments, should claim no authority for our premises save the assent we hope they will gain from our audience.”

Rorty in his conclusions makes an important point: “Carter seems to think that religious believers’ moral convictions are somehow more deeply interwoven with their self-identity than those of atheists with theirs. He seems unwilling to admit that the role of the Enlightenment ideology in giving meaning to the lives of atheists is just as great as Christianity’s role giving meaning to his own life.”

So when atheists (of the ‘new’ variety and others) say that religion does not have any special place in any discussions of public policy and should not be immune from criticism, they are not being disrespectful or rude to religion, they are merely pointing out that “a speaker’s depth of spirituality is [no] more relevant to her participation in public debate than her hobby or her hair color.”

The new atheists are simply advocating a model of good democratic politics.

Respect for religion-3: Challenging the privileged status of religion

It used to be that when religious people said something about their beliefs that you disagreed with, the polite thing to do was to keep quiet, even if you thought it wrong or baseless or just plain silly. What is happening now is that religious-based statements are being seen more and more as on a par with any other statements and suffer the same scrutiny. Why the new atheists are causing a stir is because of their willingness to say openly what many have thought but previously kept to themselves: that the basic ideas underlying religions are no different from beliefs in a flat-Earth or fairies or magic unicorns or the Flying Spaghetti Monster. Even comparing, as I have just done, mainstream religious beliefs with these other so-called ‘fringe’ beliefs is sometimes taken as insulting. But this increased willingness to say just such things has resulted in them being called ‘shrill’ or having ‘no respect for religion.’

Respect for religion-2: What are the limits?

If one wants to see how much privilege is granted to religion in the public sphere, consider what happened last week. The Congress decided to expand the provisions of so-called ‘hate crimes’ legislation. The Local Law Enforcement Hate Crimes Prevention Act of 2007 (H.R. 1592), would “provide federal assistance to states, local jurisdictions and Indian tribes to prosecute hate crimes” involving “actual or perceived religion, national origin, gender, sexual orientation, gender identity or disability.”

Respect for religion-1: Are the new atheists rude towards religion?

There are two charges that are often laid at the feet of the ‘new atheists’. One is that they are rude, shrill, angry, and otherwise disrespectful towards religion. The second is that their challenge to religious beliefs in general (as opposed to just the fundamentalist and extreme variants) makes for bad politics, since they are alienating those religious elements who act as a moderating influence in our society and with whom elite science has formed useful alliances in the past.

As to the first charge of rudeness and shrillness, this is clearly not a statement about that actual tone of the discussion conducted by the new atheists. Most of the prominent new atheists are urbane academics who are not prone to yelling or using profanity or ad hominem attacks. I have seem numerous interviews with Richard Dawkins, perhaps the most prominent of the new atheists, and never once have I heard him so much as raise his voice or even seem angry. The worst charge that can be laid against him is that he can be testy with those people who make sweeping claims about evolutionary theory without seeming to understand what the theory actually says. He is actually very mild-mannered when compared with some of the other voices one hears in the media.

So whence does this charge of rudeness arise? I think it is because the new atheists are directly challenging the idea that religious beliefs should occupy a privileged place in public discourse that shields them from the kind of scrutiny that any other belief would merit. If, for example, some public official like a member of Congress or the President were to say that he or she believed in fairies and had conversations with them, that would immediately raise questions about the mental competence of the person involved. But saying that he or she converses with god through prayer not only raises no concerns at all, it is seen as wholly admirable. The fact that people do not even see a similarity between belief in god and belief in fairies is a testament to how powerfully our society has internalized the idea that ‘respect for religion’ means that one must not point this out.
In his book The God Delusion (p. 178), Richard Dawkins quotes the anthropologist Pascal Boyer who once over dinner at a Cambridge University college recounted the beliefs of the Fang people of Cameroon who believed that “witches have an extra internal animal-like organ that flies away at night and ruins other people’s crops or poisons their blood. It is also said that these witches sometimes assemble for huge banquets, where they will devour their victims and plan future attacks. Many will tell you that a friend of a friend actually saw witches flying over the village at night, sitting on a banana leaf and throwing magical darts at various unsuspecting victims.”

Bayer says he was dumbfounded when a Cambridge theologian turned to him and said “This is what makes anthropology so fascinating and so difficult too. You have to explain how people can believe such nonsense.” (italics on original)

Dawkins points out that the theologian, as a mainstream Christian, did not see any irony at all in referring to the Fang people’s beliefs as nonsense even while he himself believed many or all of the following beliefs:

  • In the time of the ancestors, a man was born to a virgin mother with no biological father being involved.
  • The same fatherless man called out to a friend called Lazarus, who had been dead long enough to stink, and Lazarus came back to life.
  • The fatherless man himself came alive after being dead and buried three days.
  • Forty days later, the fatherless man went to the top of a hill and then disappeared bodily in to the sky.
  • If you murmur thoughts privately in your head, the fatherless man, and his ‘father’ (who is also himself) will hear your thoughts and may act upon them. He is simultaneously able to hear the thoughts of everybody else in the world.
  • If you do something bad, or something good, the same fatherless man sees all, even if nobody else does. You may be rewarded or punished accordingly, including after your death.
  • The fatherless man’s virgin mother never died but ‘ascended’ bodily into heaven.
  • Bread and wine, if blessed by a priest (who must have testicles), ‘become’ the body and blood of the fatherless man.

Note that this set of beliefs is commonly held by mainstream religious people, not just fringe groups. There will be differences amongst the various sects as to which to believe and which to reject (Catholics believe the last one which non-Catholics find preposterous) but clearly once you have accepted any one of them, it is hard to deny credibility to any of the others or to the beliefs of the Fang people.

What has disturbed the equilibrium in dialogue between elite science and elite religion is that the new atheists are saying that the beliefs of even elite religion are incompatible with a scientific outlook that values evidence. And this is what, I think, underlies the charge of rudeness, shrillness, etc. It is not the volume or tone or language or any of the other things that we normally associate with those words, but simply the fact that the new atheists have chosen to point out that, in an intellectually coherent sense, there is no such thing as a ‘respectable’ religious belief.

POST SCRIPT: Bush no longer influential?

I usually don’t pay much attention to the periodical generation of lists of the 100 best or worst this or that. Those lists tell us more about the people making up the lists than anything else. But I was intrigued by the recent release of Time magazine’s annual list of the 100 most influential people in the world and the fact that George W. Bush was not on it.

It seems absurd to me that the leader of the world’s only superpower, and a man with a proven record of creating disaster and chaos, should not be considered objectively influential, if even in a negative way. The Mayor of New York, Hillary Clinton, Condoleeza Rice, Arnold Schwarzenegger, the Israeli Foreign Minister, and Osama Bin Laden make the list but Bush doesn’t? Are there any reasonable criteria by which such an omission makes sense?

Yes, but only if you take the view that this list is not a measure of actual influence but simply measures the zeitgeist. And what Time seems to have decided is that Bush has become an embarrassment who is best ignored until the time comes when he slips away into obscurity at the end of his term, unless he is impeached first. His low approval rating of 28%, the lowest of any President since 1979, adds to his aura of being a loser.

Perhaps this cartoon by Nick Anderson, editorial cartoonist of the Houston Chronicle (in Bush’s home state no less), best represents how Bush is increasingly being perceived.

The new atheism-6: The biological origins of religion and morality

(See part 1, part 2, part 3, part 4, and part 5.)

You would think that natural selection would work against religion because those individuals who spent their time in prayer and other rituals, and used precious energy and resources in building temples and offering sacrifices, would be at a survival disadvantage when compared to those who used their time more productively. In the previous post, I outlined the basic framework of natural selection and summarized the arguments of those who explain the survival value of religion by saying that religious ideas are passed on and evolve as a byproduct of the survival advantage that accrues from young children being predisposed to believe their parents and other adult authority figures.

But while that may explain how religions propagate once they come into being, it is harder to understand how religious ideas arose in the first place. If the outbreak of religion were an occasional event occurring here or there at random, then we could just dismiss it as an anomaly, like the way that random genetic mutations cause rare diseases. But religion is not like that. As David P. Barash says in The Chronicle of Higher Education (Volume 53, Issue 33, Page B6, April 20, 200.): “On the one hand, religious belief of one sort or another seems ubiquitous, suggesting that it might well have emerged, somehow, from universal human nature, the common evolutionary background shared by all humans. On the other hand, it often appears that religious practice is fitness-reducing rather than enhancing — and, if so, that genetically mediated tendencies toward religion should have been selected against.”

The new atheism-5: The scientific approach to philosophical questions

(See part 1, part 2, part 3, and part 4.)

The biological sciences approach to the questions of the origins of religious belief and morality is not to ask what the proximate causes are that led to belief in god and the afterlife (for which the answers may be to satisfy curiosity and provide comfort) but to see what evolutionary advantage accrues to those individuals who hold such beliefs, because natural selection works on individual organisms, not groups.

To better understand how evolutionary biology addresses these questions, it is useful to review the basic tenets of evolution by natural selection. Following Philip Kitcher’s The Advancement of Science, (p.19), Darwin’s four fundamental evidentiary claims can be stated as follows:

The new atheism-4: The new questions posed by the new atheists

Religious beliefs are ubiquitous and have been around for a long time despite the lack of any convincing empirical evidence in support of the beliefs. As I have said before, the evidence asked for is not unlike the evidence required if someone says that there are three kinds of electric charge in the universe, as opposed to the two kinds that scientists currently believe in. You have to provide data to support that contention. If you don’t, people are perfectly justified in rejecting that position. To assert that a third kind of charge exists but it has no measurable and observable effect on anything is not a position that has any intellectual merit. And yet that seems to be precisely the kind of argument that elite religionists are making.

That is not the only kind of evidence that god could provide. Sam Harris in his book Letter to a Christian Nation (p. 78) points to a website that asks why the people who claim that god heals people in response to prayers never seem to pray to have the limbs of amputees re-grow, even though salamanders routinely do this without any prayer. As the website says: “If we pray for anything that is impossible — for example, regenerating an amputated limb or moving Mt. Everest to Newark, NJ — it never happens. We all know that. If we pray for anything that is possible, the results of the prayer will unfold in exact accord with the normal laws of probability.”

The new atheism-3: What the new atheists are saying

(See part 1 and part 2.)

The peaceful coexistence model that has long been used to maintain peace between elite science and elite religion was reinforced by the National Academy of Sciences when the science-religion issue became heated during the heyday of the intelligent design creationism movement. In a 1998 statement titled Teaching about Evolution and Science, the NAS said: “At the root of the apparent conflict between some religions and evolution is a misunderstanding of the critical difference between religious and scientific ways of knowing. Religions and science answer different questions about the world. . .Science is a way of knowing about the natural world. It is limited to explaining the natural world through natural causes. Science can say nothing about the supernatural. Whether God exists or not is a question about which science is neutral.”
