A Guide to Reality, Part 9

Alex Rosenberg begins chapter 4 of The Atheist’s Guide to Reality by pointing out how wasteful biological processes are. For example, a frog or fish may lay thousands or even millions of eggs and only produce a few offspring. Many organisms go through an entire life cycle without having any offspring at all. In addition, 99% of the species that have ever existed are now extinct, partly as the result of various prehistoric cataclysms (like the asteroid that wiped out the dinosaurs).

Rosenberg says this is what we should expect from the Second Law of Thermodynamics: “a lot of order relentlessly turned into entropy” [75]: 

Can any process produce entropy as fast as natural selection?… Build a lot of complicated devices out of simpler things and then destroy all of them except the few you need to build more such devices… [Adaptations] persistently get more complicated and so use even more energy to build and maintain themselves…. Any process competing with natural selection as the source of adaptations has to produce adaptations from non-adaptations and every one of the adaptations it produces will have to be rare, expensive and wasteful [77].

However, Rosenberg’s main thesis in this chapter is that it’s logically impossible to reconcile God and Darwin (although many have tried). He begins with the traditional idea that God is omniscient and omnipotent (aside from being unable to perform impossible tasks like creating a rock so heavy He or She can’t lift it). Rosenberg also assumes for the sake of argument that God intended to create us or something like us “in His image”.

So, assuming that God knows everything, can do anything, and wanted us to exist, how can we harmonize God and evolution? The common approach is to suggest that God used evolution to make us, either by kicking off the process long ago, knowing it would eventually lead to us, or by manipulating evolution at key points, with the same result. In other words, evolution is part of God’s plan.

A problem with this idea, as Rosenberg explains, is that natural selection is a matter of probabilities. That’s what we should expect from the Second Law of Thermodynamics. Mutations just happen. Organisms that might do very well never get the chance because of some random event (like being eaten while still in the nest). There is no guarantee that particular species will evolve. That’s what science tells us.

If God cooked the evolutionary books, therefore, interfering with the randomness of evolution, Darwin got it wrong. We didn’t evolve in the way the theory predicts. On the other hand, if God let evolution take its random course, He or She didn’t know what the result would be. Our evolution wasn’t planned. Either evolution is a random, probabilistic process or it isn’t. You can’t have it both ways.

My guess is that a proponent of intelligent design or creationism would say “so much for evolution”. It doesn’t work exactly like the biologists say. So what? Or that God in His infinite wisdom can arrange things any way He wants. It’s all way beyond our understanding.

Personally, I don’t have any religious faith that needs to be reconciled with Darwinism. But what if you’re serious about reconciling your faith and your scientific views? Is there a good response to Rosenberg’s argument?

I think there is. My first reaction to Rosenberg’s argument in chapter 4 is that he seems to be ignoring something he discussed in chapter 2, namely, the “multiverse”. As Rosenberg pointed out, many theoretical physicists, perhaps most of them, think that our universe is just one among many, where “many” could be a truly vast number, even an infinite number. But if there really is a multiverse, it seems beyond question that people like us were certain to evolve in universes here or there, given enough time and randomness. God, being omniscient, could have initiated the multiverse knowing full well that people just like us would eventually exist in some of its parts. If anyone would, God would understand that if you roll the dice often enough, you’ll eventually get all the combinations.

Along with Rosenberg, we can accept the fact that evolution is a truly random process in our universe. It might even be a random process in every universe. But if there are enough universes around, pretty much everything will end up evolving somewhere or other many, many times. If that’s God’s plan, there is no conflict with the Second Law or the theory of evolution. God and Darwin can be reconciled.

My other reaction to Rosenberg’s argument is that he should take into account what physicists and many philosophers say about the nature of time. I have trouble with the idea, but the current scientific view of time is that all moments are equally real. Ours is a “block” universe in which there is no past, present or future; there is merely earlier and later. It isn’t clear to me at all how the universe can be probabilistic and physical events truly random if what’s going to happen is just as real as what did happen, but that’s what physicists believe. I guess it just means the past doesn’t fully determine the future at the quantum level, even though future events are just as real as past events. 

Anyway, if anyone can reconcile quantum indeterminacy and a block universe, it’s God. After all, according to the theologians, God is outside of time (whatever that means). God isn’t sitting around, waiting to see what happens. As Rosenberg says, God is “omnipresent”, which means there is nothing in space or time that is off-limits to God. Being omniscient as well, God knows the whole story. That should be especially easy for God if earlier and later events in the story are equally real.

For that reason, even if evolution is random and inherently unpredictable, God is fully informed. Every event, earlier or later, is right there in the history of the universe for God to know about. If what physics tells us is true, it’s a perfect setup for someone like God, being outside of time, to know how evolution eventually leads to people like us. Randomness prevails, Darwinism is correct and God knows the whole story anyway. If indeterminacy and the supposed nature of time are in harmony, so are physics, Darwin and God. 

Rosenberg ends chapter 4 with some remarks on purpose:

Scientism means that we have to be nihilists about the purpose of things in general, about the purpose of biological life in particular, and the purpose of human life as well….There isn’t any rhyme or reason to the universe. It’s just one damn thing after another. Real purpose has been ruled out by physics [92].

I don’t think he’s right about that, but to avoid repeating myself, we’re going to move on. In our next installment, we’ll consider chapter 5. It’s called “Morality: the Bad News” (the good news supposedly comes later).

Zealot: The Life and Times of Jesus of Nazareth by Reza Aslan

Zealot might be disturbing for Christian readers. Its author was born into a Muslim family in Iran. After his family emigrated to the United States, he became a Christian for a while. After closely studying the origins of Christianity, however, he became “a more genuinely committed disciple of Jesus of Nazareth than [he] ever was of Jesus Christ”.

As Aslan tells the story, Jesus was born in the humble village of Nazareth, not in a manger in Bethlehem (despite what the Bible says, the Romans never conducted a census that forced everyone to stop work and travel to their birthplace). Jesus was illiterate, worked as a laborer and was probably married (almost all young Jewish men got married in those days). When he was roughly 34 years old, he left Nazareth and began preaching a politically-charged message to his fellow Jews.

At the time, there were lots of angry but hopeful Jews in Palestine. They were anticipating the arrival of a messiah, someone who would establish the Kingdom of God on earth and get rid of the Romans. Some claimed to be the messiah. Others were thought to be the messiah by their followers. Some, including Jesus, were said to have performed exorcisms or miracles. What the various preachers, dissidents, rabble rousers and zealots had in common was their nationalistic desire to kick the Romans out of Palestine and restore Israel to its former glory. 

None of these supposed messiahs claimed to be divine, however. The Jews, of course, were strictly monotheistic. It was enough that the messiah do God’s work by overthrowing the Roman oppressors. Many also hoped for economic reforms, like lower taxes. Jesus, in particular, apparently had a very low opinion of the wealthy priests and merchants who cooperated with the Romans.

Crucifixion was a common punishment for Rome’s enemies, so it was no surprise that Jesus was found guilty of sedition after a few years and executed. Being crucified, however, showed that Jesus wasn’t the messiah after all. The Romans were clearly still in power. Jesus had failed to institute the Kingdom of God. Aslan suggests that some of Jesus’s followers wanted to explain away his apparent failure. They spread the idea that Jesus rose from the dead and would one day return to finish his work. That’s when the Romans would finally be overthrown.

We know that the various books of the New Testament were written decades after Jesus’s crucifixion. We also know that almost all of it was written by men who never met Jesus, never heard him speak and never saw him perform any miracles. Aslan points out lots of inconsistencies and omissions in the New Testament and plausibly argues that many stories told about Jesus were designed to satisfy political and theological agendas. For example, claiming that Jesus was born in Bethlehem was a way to make his birthplace consistent with earlier prophecies about the messiah.

What I found especially interesting in Zealot was Aslan’s discussion of the apostle Paul, who wasn’t one of the original twelve apostles. He was a Jew and a Roman citizen who is said to have encountered an otherworldly Jesus on the road to Damascus a few years after Jesus’s crucifixion.

Whether or not Paul had a vision while traveling to Damascus, he doesn’t seem to have written anything saying that he did (the road to Damascus story is now attributed to Luke, who was apparently one of Paul’s disciples). But, according to Aslan, Paul was mainly responsible for the birth of Christianity as a religion separate from Judaism.

Jesus, of course, was hardly a Christian himself. For example, Aslan says there is no evidence that Jesus ever referred to himself as the “Son of God”. That was a title reserved for the past kings of Israel, like David. It was Paul who promoted the story that Jesus was divine and began referring to Jesus as “Jesus Christ”. Paul also founded churches in other parts of the Roman empire. In fact, more than half of the New Testament was either written by Paul or is about Paul.

Paul’s distinctive views were rejected by the other apostles (the ones who had known Jesus and were still alive), including James the Just, the younger brother of Jesus and the leading figure among the apostles after Jesus’s death. Since Paul couldn’t convince the other Jews that Jesus was divine, he concentrated on convincing the gentiles, some of whom were receptive to his relatively monotheistic message.

Of course, the historical record is extremely spotty with regard to Jesus. Some scholars no doubt disagree with Aslan’s interpretation of the evidence. A Christian, being convinced that Jesus was a unique individual who actually did perform miracles, actually was resurrected and actually was (and is) God’s son, might say it’s pointless to try to understand Jesus from an historical perspective.

In addition, Aslan never really explains why he holds Jesus of Nazareth in such high regard (even if Jesus was anti-Rome and a champion of the poor). Aslan doesn’t even emphasize Jesus’s role as a moral teacher, arguing that the idea of turning the other cheek, for example, didn’t apply to people in general – it only applied to one’s Jewish enemies (and certainly not to Romans, for whom the sword was more appropriate). But I found Aslan’s account extremely interesting and very plausible. Here is part of his concluding summary:

Christianity after the destruction of Jerusalem [by the Romans in 70 C.E.] was almost exclusively a gentile religion; it needed a gentile theology. And that is precisely what Paul provided. The choice between James’s vision of a Jewish religion anchored in the Law of Moses and derived from a Jewish nationalist who fought against Rome, and Paul’s vision of a Roman religion that divorced itself from Jewish provincialism and require nothing for salvation save belief in Christ, was not a difficult one for the second and third generations of Jesus’s followers…

Two thousand years later, the Christ of Paul’s creation has utterly subsumed the Jesus of history. The memory of the revolutionary zealot who walked across Galilee gathering an army of disciples with the goal of establishing the Kingdom of God on earth, the magnetic preacher who defied the authority of the Temple priesthood in Jerusalem, the radical Jewish nationalist who challenged the Roman occupation and lost, has been almost completely lost to history.

Stupid Remarks Continue to Offend and Entertain

We who make, report, attack or defend stupid remarks have helped make the Internet what it is today, whatever that is. As my 160 (!) followers would attest, I’ve made my own tiny contribution to this ongoing effort. That is, they would attest if any of them actually read the stuff I painstakingly write here at WOCS. (Unfortunately, Internet statistics don’t lie.)

Furthermore, I promise to keep contributing as long as Republicans keep talking.

Keeping with this practice, although in a relatively non-political vein, I’m now going to discuss a few stupid remarks that have recently been reported, criticized and even defended.

First, it’s hardly worth noting that someone on FOX TV said that Santa Claus is white and Jesus was too. As a friend recently pointed out, saying things like that is what people on FOX do for a living. What was more remarkable was the story about a New Mexico high school teacher who criticized a black student’s decision to dress up as Santa Claus, implying that it would have been better if he had dressed up as an elf, reindeer or candy cane. 

According to the school district, the teacher apologized and was placed on “administrative leave”, so there is some truth to this story. Even though the student was deeply embarrassed, I hope the teacher was making a joke (the kind of jocular remark colloquially known in some quarters as “breaking balls”, as in “Hey, Ralph, don’t you know Santa Claus was white!” “No, I thought he was Italian.” “Boom!”). If the teacher wasn’t trying to be funny, we’d have to conclude that yet another education professional has lost his or her mind.

Another recent controversy involves a person with a very long beard who is part of a TV show called “Duck Dynasty”. He got into trouble when he said that it’s more logical for a man to want to put his penis in a vagina than in another man’s butt, suggesting that vaginal intercourse should be more pleasurable for a man than gay anal intercourse. He added, in an apparent attempt at explanation, that sin (in this case, gay sex) isn’t logical. It seems clear from the context that he wasn’t joking.

Now, it isn’t surprising that this person believes gay sex is sinful. Lots of misguided people believe that and say it all the time, even people who aren’t on FOX or in Congress. Nor is it interesting that he thinks sin is illogical. After all, if there are such things as sins, you could wind up in Hell by committing one (that, as Randy Newman once sang, would put you in a terrible position).

What I thought was interesting about this particular stupid remark was that the speaker may misunderstand evolution (even though he apparently spends a lot of time outdoors). It does make sense that vaginal intercourse is pleasurable for both men and women, because men and women who enjoy it tend to have children who will enjoy it too (and so on, and so on, until the nth generation). But that’s no reason to think that a person with a penis might not get a lot of pleasure, and even more pleasure, from putting it somewhere else or doing something else with it. Behavior evolves because it contributes to the survival of one’s offspring, not because it’s more pleasurable than other behavior. People on TV should grasp standard biological principles like this.

A third stupid remark hasn’t received much attention, so far as I know. But it’s also interesting in a way. A woman who works for a “leading internet and media company” sent this out on Twitter yesterday: “Going to Africa. Hope I don’t get AIDS. Just kidding. I’m white!” In this case, the speaker claimed to be making a joke.

When I read about this, I had the impression I’d heard the joke before. Then I remembered watching a video of Sarah Silverman telling a similar joke at a benefit concert:  “Last month I did two benefits. One was for AIDS… It was great, but tonight’s benefit is going to be better. I won’t have to worry about who I hook up with. (pause) That’s terrible! (pause) WHOM I hook up with!”. She got a very big laugh.

What would the reaction have been if it was funny Sarah Silverman who tweeted the Africa AIDS remark? People on Twitter might have thought it wasn’t up to her usual comedic standards instead of calling her a stupid racist. I wonder if Justine Sacco’s co-workers in the London office of IAC thought her tweet was yet another example of Justine being her wild and crazy self (as when, earlier this year, she tweeted “I can’t be fired for things I say while intoxicated right?”).

It’s doubtful, but perhaps Justine Sacco goes to Africa on her vacation every year to work with AIDS patients. But, so far as most of us are concerned, she might as well be a talking, albeit insensitive, dog (ok, I’ve finished writing this post, will someone take me for a walk now?).

Breaking news update!!! Steve Martin has apologized for tweeting a lame joke about the African-American spelling of “lasagna” yesterday. Communication continues to be a dangerous thing, even for talented communicators. (The TMZ site, by the way, actually labeled this story BREAKING NEWS.)

Woof, woof!

A Guide to Reality, Part 3

Continuing to work through The Atheist’s Guide to Reality by Alex Rosenberg:

Professor Rosenberg begins chapter 1 by explaining why he’s not going to spend much time arguing for atheism: others, especially David Hume, have already done that quite well; such arguments, even very good ones, don’t convince true believers; and anyway, it’s more important to understand how science can help us live without illusions than to keep talking about religion.

Instead, Rosenberg is going to discuss a view called “scientism”. As he notes, “scientism” is usually applied in a negative way to people who supposedly worship science, or try to extend it beyond its natural borders, or simply take it too seriously. Rosenberg welcomes the term, defining it this way:

[Scientism] is the conviction that the methods of science are the only reliable ways to secure knowledge of anything; that science’s description of the world is correct in its fundamentals; and that when “complete”, what science tells us will not be surprisingly different from what it tells us today (6-7).

The idea that the current scientific description of the word is fundamentally accurate is known among philosophers as “scientific realism”. The Stanford Encyclopedia of Philosophy defines it as “a positive epistemic attitude towards the content of our best [scientific] theories and models, recommending belief in both observable and unobservable aspects of the world described by the sciences”. In other words, science is a highly reliable way to acquire knowledge of the world. Science allows us to learn about the world as it is, independent of our minds. Science even allows us to find out about things we can’t directly observe, like the Big Bang and sub-atomic particles.

Rosenberg is clearly a scientific realist. Not all philosophers are (they, in fact, disagree to some extent about what science is). But Rosenberg’s scientism goes beyond simple scientific realism when he asserts that “the methods of science are the only reliable ways to secure knowledge of anything”.

Maybe he’s exaggerating on purpose (not something philosophers ordinarily do), but are you and I doing science when we look out the window and agree that it’s snowing? Is a student doing science when she concludes that Socrates was mortal if Socrates was a man and all men are mortal? As Rosenberg knows, of course, science relies on occasionally unreliable activities like seeing and hearing in order to gather evidence. Even though scientists don’t rely on a single person’s observations, they do use the same perceptual abilities the rest of us employ to acquire knowledge. In addition, most of us would agree that people clearly know lots of things that aren’t “scientific” in the usual sense (including math, logic, historical facts, cultural practices and whether the Ford is in the driveway).

Perhaps it’s enough that an adherent of scientism believes that, when applied correctly, the various methods of science are by far the best ways we have to get at the truth about many or most features of the world. Those methods include classification, observation, experimentation, measurement, replication, discussion, publication and other things physicists, chemists, biologists and psychologists regularly do.That seems right to me, but I don’t think it’s enough for Rosenberg.

Before moving on, I should mention that Rosenberg also considers this question: if science is such a reliable method of determining the truth, why do so many people reject scientific conclusions? One reason, of course, is that scientific results are often revised. Another is that scientists often disagree among themselves, especially on topics that make the news, in some cases because they are influenced by un-scientific factors, like working for Exxon. Yet another big reason why many are skeptical about science is that scientific conclusions often make people uncomfortable (as in the case of climate change, for example).

Rosenberg, however, mainly discusses the human need for “stories”, by which he means our tendency to understand the world in terms of personalities and purposes. He argues that our ancestors became good at recognizing and interpreting purposeful behavior because that skill made it much easier to live and prosper among other people. Evolution, however, overshot the mark. People heard thunder and concluded that Someone was angry. Today, according to Rosenberg, people have trouble understanding math and physics because their subject matter doesn’t include human beings or other creatures doing things. In other words, science is especially hard because most people haven’t been built (through evolution) to understand it. Religion, on the other hand, often involves stories, which we generally find more easy to understand than science.

In the next installment: physics and the nature of reality.

Pope Francis on Economic Tyranny and the “Deified Market”

Pope Francis I has issued his first apostolic exhortation to the “bishops, clergy, consecrated persons and the lay faithful”. It’s called Evangelii Gaudium (“The Joy of the Gospel”). 

The most joyful part for many of us will be his comments on the global economy. He wants the world to say “No to an economy of exclusion”, “No to the new idolatry of money”, “No to a financial system which rules rather than serves” and “No to the inequality which spawns violence”.

Will his words affect those of us, Catholic or not, who would rather cut food stamps than regulate banks? Probably not, but it’s still great to hear the Pope talk like a Christian.

Quoted at length from the Vatican’s website:

53. Just as the commandment “Thou shalt not kill” sets a clear limit in order to safeguard the value of human life, today we also have to say “thou shalt not” to an economy of exclusion and inequality. Such an economy kills….Today everything comes under the laws of competition and the survival of the fittest, where the powerful feed upon the powerless. As a consequence, masses of people find themselves excluded and marginalized: without work, without possibilities, without any means of escape.

Human beings are themselves considered consumer goods to be used and then discarded. We have created a “disposable” culture which is now spreading. It is no longer simply about exploitation and oppression, but something new. Exclusion ultimately has to do with what it means to be a part of the society in which we live; those excluded are no longer society’s underside or its fringes or its disenfranchised – they are no longer even a part of it. The excluded are not the “exploited” but the outcast, the “leftovers”.

54. In this context, some people continue to defend trickle-down theories which assume that economic growth, encouraged by a free market, will inevitably succeed in bringing about greater justice and inclusiveness in the world. This opinion, which has never been confirmed by the facts, expresses a crude and naïve trust in the goodness of those wielding economic power and in the sacralized workings of the prevailing economic system. Meanwhile, the excluded are still waiting. To sustain a lifestyle which excludes others, or to sustain enthusiasm for that selfish ideal, a globalization of indifference has developed. Almost without being aware of it, we end up being incapable of feeling compassion at the outcry of the poor, weeping for other people’s pain, and feeling a need to help them, as though all this were someone else’s responsibility and not our own. The culture of prosperity deadens us; we are thrilled if the market offers us something new to purchase; and in the meantime all those lives stunted for lack of opportunity seem a mere spectacle; they fail to move us. 

55. One cause of this situation is found in our relationship with money, since we calmly accept its dominion over ourselves and our societies. The current financial crisis can make us overlook the fact that it originated in a profound human crisis: the denial of the primacy of the human person! We have created new idols. The worship of the ancient golden calf … has returned in a new and ruthless guise in the idolatry of money and the dictatorship of an impersonal economy lacking a truly human purpose. The worldwide crisis affecting finance and the economy lays bare their imbalances and, above all, their lack of real concern for human beings; man is reduced to one of his needs alone: consumption.

56. While the earnings of a minority are growing exponentially, so too is the gap separating the majority from the prosperity enjoyed by those happy few. This imbalance is the result of ideologies which defend the absolute autonomy of the marketplace and financial speculation. Consequently, they reject the right of states, charged with vigilance for the common good, to exercise any form of control. A new tyranny is thus born, invisible and often virtual, which unilaterally and relentlessly imposes its own laws and rules. Debt and the accumulation of interest also make it difficult for countries to realize the potential of their own economies and keep citizens from enjoying their real purchasing power. To all this we can add widespread corruption and self-serving tax evasion, which have taken on worldwide dimensions. The thirst for power and possessions knows no limits. In this system, which tends to devour everything which stands in the way of increased profits, whatever is fragile, like the environment, is defenseless before the interests of a deified market, which become the only rule. 

57. Behind this attitude lurks a rejection of ethics and a rejection of God. Ethics has come to be viewed with a certain scornful derision. It is seen as counterproductive, too human, because it makes money and power relative. It is felt to be a threat, since it condemns the manipulation and debasement of the person. In effect, ethics leads to a God who calls for a committed response which is outside of the categories of the marketplace. When these latter are absolutized, God can only be seen as uncontrollable, unmanageable, even dangerous, since he calls human beings to their full realization and to freedom from all forms of enslavement. Ethics – a non-ideological ethics – would make it possible to bring about balance and a more humane social order. With this in mind, I encourage financial experts and political leaders to ponder the words of one of the sages of antiquity: “Not to share one’s wealth with the poor is to steal from them and to take away their livelihood. It is not our own goods which we hold, but theirs”.

58. A financial reform open to such ethical considerations would require a vigorous change of approach on the part of political leaders. I urge them to face this challenge with determination and an eye to the future, while not ignoring, of course, the specifics of each case. Money must serve, not rule! The Pope loves everyone, rich and poor alike, but he is obliged in the name of Christ to remind all that the rich must help, respect and promote the poor. I exhort you to generous solidarity and a return of economics and finance to an ethical approach which favours human beings.

59. Today in many places we hear a call for greater security. But until exclusion and inequality in society and between peoples is reversed, it will be impossible to eliminate violence. The poor and the poorer peoples are accused of violence, yet without equal opportunities the different forms of aggression and conflict will find a fertile terrain for growth and eventually explode. When a society – whether local, national or global – is willing to leave a part of itself on the fringes, no political programmes or resources spent on law enforcement or surveillance systems can indefinitely guarantee tranquility. This is not the case simply because inequality provokes a violent reaction from those excluded from the system, but because the socioeconomic system is unjust at its root. Just as goodness tends to spread, the toleration of evil, which is injustice, tends to expand its baneful influence and quietly to undermine any political and social system, no matter how solid it may appear. If every action has its consequences, an evil embedded in the structures of a society has a constant potential for disintegration and death. It is evil crystallized in unjust social structures, which cannot be the basis of hope for a better future. We are far from the so-called “end of history”, since the conditions for a sustainable and peaceful development have not yet been adequately articulated and realized.

60. Today’s economic mechanisms promote inordinate consumption, yet it is evident that unbridled consumerism combined with inequality proves doubly damaging to the social fabric. Inequality eventually engenders a violence which recourse to arms cannot and never will be able to resolve. This serves only to offer false hopes to those clamouring for heightened security, even though nowadays we know that weapons and violence, rather than providing solutions, create new and more serious conflicts. Some simply content themselves with blaming the poor and the poorer countries themselves for their troubles; indulging in unwarranted generalizations, they claim that the solution is an “education” that would tranquilize them, making them tame and harmless. All this becomes even more exasperating for the marginalized in the light of the widespread and deeply rooted corruption found in many countries – in their governments, businesses and institutions – whatever the political ideology of their leaders.
