Review: In case you need a refresher on the cosmological and fine-tuning arguments, as presented by a professor of particle physics at Stanford University, then click this link and watch the lecture.

If you already know about the standard arguments for theism from cosmology, then take a look at this post on Uncommon Descent.

Summary:

In my previous post, I highlighted three common atheistic objections to to the cosmological fine-tuning argument. In that post, I made no attempt to answer these objections. My aim was simply to show that the objections were weak and inconclusive.

Let’s go back to the original three objections:

1. If the universe was designed to support life, then why does it have to be so BIG, and why is it nearly everywhere hostile to life? Why are there so many stars, and why are so few orbited by life-bearing planets? (Let’s call this the size problem.)

2. If the universe was designed to support life, then why does it have to be so OLD, and why was it devoid of life throughout most of its history? For instance, why did life on Earth only appear after 70% of the cosmos’s 13.7-billion-year history had already elapsed? And Why did human beings (genus Homo) only appear after 99.98% of the cosmos’s 13.7-billion-year history had already elapsed? (Let’s call this the age problem.)

3. If the universe was designed to support life, then why does Nature have to be so CRUEL? Why did so many animals have to die – and why did so many species of animals have to go extinct (99% is the commonly quoted figure), in order to generate the world as we see it today? What a waste! And what about predation, parasitism, and animals that engage in practices such as serial murder and infant cannibalism? (Let’s call this the death and suffering problem.)

In today’s post, I’m going to try to provide some positive answers to the first two questions: the size problem and the age problem.

Here’s an excerpt for the size argument:

(a) The main reason why the universe is as big as it currently is that in the first place, the universe had to contain sufficient matter to form galaxies and stars, without which life would not have appeared; and in the second place, the density of matter in the cosmos is incredibly fine-tuned, due to the fine-tuning of gravity. To appreciate this point, let’s go back to the earliest time in the history of the cosmos that we can meaningfully talk about: the Planck time, when the universe was 10^-43 seconds old. If the density of matter at the Planck time had differed from the critical density by as little as one part in 10^60, the universe would have either exploded so rapidly that galaxies wouldn’t have formed, or collapsed so quickly that life would never have appeared. In practical terms: if our universe, which contains 10^80 protons and neutrons, had even one more grain of sand in it – or one grain less – we wouldn’t be here.

If you mess with the size of the universe, you screw up the mass density fine-tuning. We need that to have a universe that expands at the right speed in order for the matter to clump together to form galaxies, stars and planets. Too fast, and you get no clumping. Too slow, and the whole thing re-collapses into a hot fireball. You need stars and planets to have a place to form life – a place with liquid water at the surface, and more.

And an excerpt for the age argument:

(a) One reason why we need an old universe is that billions of years were required for Population I stars (such as our sun) to evolve. These stars are more likely to harbor planets such as our Earth, because they contain lots of “metals” (astronomer-speak for elements heavier than helium), produced by the supernovae of the previous generation of Population II stars. According to currently accepted models of Big Bang nucleosynthesis, this whole process was absolutely vital, because the Big Bang doesn’t make enough “metals”, including those necessary for life: carbon, nitrogen, oxygen, phosphorus and so on.

Basically, you need heavy elements to make stars that burn slow and steady, as well as to make PEOPLE! And heavy elements have to be built up slowly through several iterations of the stellar lifecycle, including the right kinds of stellar death: supernovae.

Read the rest! These arguments come up all the time in debates with village atheists like Christopher Hitchens and Richard Dawkins. It’s a smokescreen they put up, but you’ve got to be able to answer it using the scientific evidence we have today. They always want to dismiss God with their personal preferences about what God should or should not do. But the real issue is the design of the cosmological constants that allow life to anywhere. That’s the part that’s designed. And that’s not a matter of personal preference, it’s a matter of mathematics and experimental science.

One last parting shot. If God made the universe have life everywhere, the first thing atheists would say is “See? Life evolves fine by itself without any God!” The only way to recognize a marksman is when he hits a narrow target (not hostile to life) from a wide range of possibilities that have no value (hostile to life). We don’t credit Chris Kyle for hitting the wall above an Islamic terrorist from a mile away, we credit Chris Kyle for hitting an Islamic terrorist a mile away. The design is not how much of the universe is hospitable to life versus how much is hostile to life. The design is in the cosmological constants – where we are in the narrow band that is hospitable to life and not in the huge regions that are hostile to life.

You can read the best explanation of the design argument in this lecture featuring Robin Collins. That link goes to my post which has a summary of the lecture. He has a new lecture that I also blogged about where he extends the fine-tuning argument down to the level of particle physics. I have a summary of that one as well.

Correcting four myths about the history of the Crusades

6 Comments

Here is an interesting article from First Principles Journal.

Intro:

The verdict seems unanimous. From presidential speeches to role-playing games, the crusades are depicted as a deplorably violent episode in which thuggish Westerners trundled off, unprovoked, to murder and pillage peace-loving, sophisticated Muslims, laying down patterns of outrageous oppression that would be repeated throughout subsequent history. In many corners of the Western world today, this view is too commonplace and apparently obvious even to be challenged.

But unanimity is not a guarantee of accuracy. What everyone “knows” about the crusades may not, in fact, be true. From the many popular notions about the crusades, let us pick four and see if they bear close examination.

The four myths:

  • Myth #1: The crusades represented an unprovoked attack by Western Christians on the Muslim world.
  • Myth #2: Western Christians went on crusade because their greed led them to plunder Muslims in order to get rich.
  • Myth #3: Crusaders were a cynical lot who did not really believe their own religious propaganda; rather, they had ulterior, materialistic motives.
  • Myth #4: The crusades taught Muslims to hate and attack Christians.

Here’s the most obvious thing you should know. The Crusades were defensive actions:

In a.d. 632, Egypt, Palestine, Syria, Asia Minor, North Africa, Spain, France, Italy, and the islands of Sicily, Sardinia, and Corsica were all Christian territories. Inside the boundaries of the Roman Empire, which was still fully functional in the eastern Mediterranean, orthodox Christianity was the official, and overwhelmingly majority, religion. Outside those boundaries were other large Christian communities—not necessarily orthodox and Catholic, but still Christian. Most of the Christian population of Persia, for example, was Nestorian. Certainly there were many Christian communities in Arabia.

By a.d. 732, a century later, Christians had lost Egypt, Palestine, Syria, North Africa, Spain, most of Asia Minor, and southern France. Italy and her associated islands were under threat, and the islands would come under Muslim rule in the next century. The Christian communities of Arabia were entirely destroyed in or shortly after 633, when Jews and Christians alike were expelled from the peninsula.6 Those in Persia were under severe pressure. Two-thirds of the formerly Roman Christian world was now ruled by Muslims.

What had happened? Most people actually know the answer, if pressed—though for some reason they do not usually connect the answer with the crusades. The answer is the rise of Islam. Every one of the listed regions was taken, within the space of a hundred years, from Christian control by violence, in the course of military campaigns deliberately designed to expand Muslim territory at the expense of Islam’s neighbors. Nor did this conclude Islam’s program of conquest. The attacks continued, punctuated from time to time by Christian attempts to push back. Charlemagne blocked the Muslim advance in far western Europe in about a.d. 800, but Islamic forces simply shifted their focus and began to island-hop across from North Africa toward Italy and the French coast, attacking the Italian mainland by 837. A confused struggle for control of southern and central Italy continued for the rest of the ninth century and into the tenth. In the hundred years between 850 and 950, Benedictine monks were driven out of ancient monasteries, the Papal States were overrun, and Muslim pirate bases were established along the coast of northern Italy and southern France, from which attacks on the deep inland were launched. Desperate to protect victimized Christians, popes became involved in the tenth and early eleventh centuries in directing the defense of the territory around them.

If you asked me what are the two best books on the Crusades, I would answer God’s Battalions: The Case for the Crusades by Baylor professor Rodney Stark and The Concise History of the Crusades by Professor Thomas F. Madden. If you get this question a lot from atheists, then I recommend you pick these up. Anything by Rodney Stark is useful for Christians, in fact.

Why doesn’t God make his existence more obvious to people?

Have you ever heard someone say that if God existed, he would give us more evidence? This is called the “hiddenness of God” argument. It’s also known as the argument from “rational non-belief”.

Basically the argument is something like this:

  1. God is all powerful
  2. God is all loving
  3. God wants all people to know about him
  4. Some people don’t know about him
  5. Therefore, there is no God.

In this argument, the atheist is saying that he’s looked for God real hard and that if God were there, he should have found him by now. After all, God can do anything he wants that’s logically possible, and he wants us to know that he exists. To defeat the argument we need to find a possible explanation of why God would want to remain hidden when our eternal destination depends on our knowledge of his existence.

What reason could God have for remaining hidden?

Dr. Michael Murray, a brilliant professor of philosophy at Franklin & Marshall College, has found a reason for God to remain hidden.

His paper on divine hiddenness is here:
“Coercion and the Hiddenness of God“, American Philosophical Quarterly, Vol 30, 1993.

He argues that if God reveals himself too much to people, he takes away our freedom to make morally-significant decisions, including responding to his self-revelation to us. Murray argues that God stays somewhat hidden, so that he gives people space to either 1) respond to God, or 2) avoid God so we can keep our autonomy from him. God places a higher value on people having the free will to respond to him, and if he shows too much of himself he takes away their free choice to respond to him, because once he is too overt about his existence, people will just feel obligated to belief in him in order to avoid being punished.

But believing in God just to avoid punishment is NOT what God wants for us. If it is too obvious to us that God exists and that he really will judge us, then people will respond to him and behave morally out of self-preservation. But God wants us to respond to him out of interest in him, just like we might try to get to know someone we admire. God has to dial down the immediacy of the threat of judgment, and the probability that the threat is actual. That leaves it up to us to respond to God’s veiled revelation of himself to us, in nature and in Scripture.

(Note: I think that we don’t seek God on our own, and that he must take the initiative to reach out to us and draw us to him. But I do think that we are free to resist his revelation, at which point God stops himself short of coercing our will. We are therefore responsible for our own fate).

The atheist’s argument is a logical/deductive argument. It aims to show that there is a contradiction between God’s will for us and his hiding from us. In order to derive a contradiction, God MUST NOT have any possible reason to remain hidden. If he has a reason for remaining hidden that is consistent with his goodness, then the argument will not go through.

When Murray offers a possible reason for God to remain hidden in order to allow people to freely respond to him, then the argument is defeated. God wants people to respond to him freely so that there is a genuine love relationship – not coercion by overt threat of damnation. To rescue the argument, the atheist has to be able to prove that God could provide more evidence of his existence without interfering with the free choice of his creatures to reject him.

Murray has defended the argument in works published by prestigious academic presses such as Cambridge University Press, (ISBN: 0521006104, 2001) and Routledge (ISBN: 0415380383, 2007).
