The kalam cosmological argument defended in a peer-reviewed science journal

10 Comments

Here’s the peer-reviewed article. It appears in a scientific journal focused on astrophysics.

Here’s the abstract:

Both cosmology and philosophy trace their roots to the wonder felt by the ancient Greeks as they contemplated the universe. The ultimate question remains why the universe exists rather than nothing. This question led Leibniz to postulate the existence of a metaphysically necessary being, which he identified as God. Leibniz’s critics, however, disputed this identification, claiming that the space-time universe itself may be the metaphysically necessary being. The discovery during this century that the universe began to exist, however, calls into question the universe’s status as metaphysically necessary, since any necessary being must be eternal in its existence. Although various cosmogonic models claiming to avert the beginning of the universe predicted by the standard model have been and continue to be offered, no model involving an eternal universe has proved as plausible as the standard model. Unless we are to assert that the universe simply sprang into being uncaused out of nothing, we are thus led to Leibniz’s conclusion. Several objections to inferring a supernatural cause of the origin of the universe are considered and found to be unsound.

The whole text of the article is posted online here.

Here’s an excerpt in which the author, Dr. William Lane Craig, explains the Big Bang cosmology:

The monumental significance of the Friedman-Lemaitre model lay in its historization of the universe. As one commentator has remarked, up to this time the idea of the expansion of the universe “was absolutely beyond comprehension. Throughout all of human history the universe was regarded as fixed and immutable and the idea that it might actually be changing was inconceivable.”{8} But if the Friedman-Lemaitre model were correct, the universe could no longer be adequately treated as a static entity existing, in effect, timelessly. Rather the universe has a history, and time will not be matter of indifference for our investigation of the cosmos. In 1929 Edwin Hubble’s measurements of the red-shift in the optical spectra of light from distant galaxies,{9} which was taken to indicate a universal recessional motion of the light sources in the line of sight, provided a dramatic verification of the Friedman-Lemaitre model. Incredibly, what Hubble had discovered was the isotropic expansion of the universe predicted by Friedman and Lemaitre. It marked a veritable turning point in the history of science. “Of all the great predictions that science has ever made over the centuries,” exclaims John Wheeler, “was there ever one greater than this, to predict, and predict correctly, and predict against all expectation a phenomenon so fantastic as the expansion of the universe?”{10}

As a GTR-based theory, the Friedman-Lemaitre model does not describe the expansion of the material content of the universe into a pre-existing, empty, Newtonian space, but rather the expansion of space itself. This has the astonishing implication that as one reverses the expansion and extrapolates back in time, space-time curvature becomes progressively greater until one finally arrives at a singular state at which space-time curvature becomes infinite. This state therefore constitutes an edge or boundary to space-time itself. P. C. W. Davies comments,

An initial cosmological singularity . . . forms a past temporal extremity to the universe. We cannot continue physical reasoning, or even the concept of spacetime, through such an extremity. . . . On this view the big bang represents the creation event; the creation not only of all the matter and energy in the universe, but also of spacetime itself.{11}

The popular expression “Big Bang,” originally a derisive term coined by Fred Hoyle to characterize the beginning of the universe predicted by the Friedman-Lemaitre model, is thus potentially misleading, since the expansion cannot be visualized from the outside (there being no “outside,” just as there is no “before” with respect to the Big Bang).{12}

The standard Big Bang model thus describes a universe which is not eternal in the past, but which came into being a finite time ago. Moreover,–and this deserves underscoring–the origin it posits is an absolute origin ex nihilo. For not only all matter and energy, but space and time themselves come into being at the initial cosmological singularity. As Barrow and Tipler emphasize, “At this singularity, space and time came into existence; literally nothing existed before the singularity, so, if the Universe originated at such a singularity, we would truly have a creation ex nihilo.“{13}

[…]On such a model the universe originates ex nihilo in the sense that at the initial singularity it is true that There is no earlier space-time point or it is false that Something existed prior to the singularity.

Every theist should be able to understand and defend this argument. It is a scientific refutation of materialism, and it is supported by six lines of scientific evidence – all of which emerged as science has progressed.

Scientific evidence:

  1. Einstein’s theory of general relativity (GTR)
  2. the red-shifting of light from distant galaxies implies an expanding universe
  3. the cosmic background radiation (which also disproves the oscillating model of the universe)
  4. the second law of thermodynamics applied to star formation theory
  5. hydrogen-helium abundance predictions
  6. radioactive element abundance predictions

Those are the scientific discoveries that have led us to the beginning of the universe, which support’s Dr. Craig’s argument.

This is the kind of evidence I expect all Christian theists to be using when discussing the question of whether God exists. Scientific evidence. When talking to non-Christians, we first need to show that we understand science, because science is a reliable and respected way of getting knowledge about the universe. Non-Christians do not accept the Bible, but they do accept science, so we begin evangelism with science. Science (experimental, testable, repeatable science) should set limits on what anyone can believe – including non-Christians, who might otherwise not be inclined to listen to Bible verses and theology. Important: it’s not a good idea to discuss the resurrection of Jesus with a person who does not accept the scientific evidence for a Creator of the universe.

The Big Bang is not compatible with atheism

According to the Secular Humanist Manifesto, atheism is committed to an eternally existing universe, (See the first item: “Religious humanists regard the universe as self-existing and not created.”). If something non-material brought all existing matter into being, that would be a supernatural cause, and atheists deny that anything supernatural exists. The standard Big Bang theory requires that all the matter in the universe come into being out of nothing. This falsifies eternal models of the universe, which are required by the atheistic worldview.

Ryan T. Anderson presents the case for natural / traditional marriage

Does government provide incentives for people to get married?
What effects does redefining marriage have on society?

A must-read long paper from the Heritage Foundation. It’s a great concise presentation of the reasons why the United States should not redefine marriage. (H/T A tweet from Ryan T. Anderson)

Abstract:

Marriage is based on the truth that men and women are complementary, the biological fact that reproduction depends on a man and a woman, and the reality that children need a mother and a father. Redefining marriage does not simply expand the existing understanding of marriage; it rejects these truths. Marriage is society’s least restrictive means of ensuring the well-being of children. By encouraging the norms of marriage—monogamy, sexual exclusivity, and permanence—the state strengthens civil society and reduces its own role. The future of this country depends on the future of marriage. The future of marriage depends on citizens understanding what it is and why it matters and demanding that government policies support, not undermine, true marriage.

Excerpt:

Supporters of redefinition use the following analogy: Laws defining marriage as a union of a man and a woman are unjust—fail to treat people equally—exactly like laws that prevented interracial marriage. Yet such appeals beg the question of what is essential to marriage. They assume exactly what is in dispute: that gender is as irrelevant as race in state recognition of marriage. However, race has nothing to with marriage, and racist laws kept the races apart. Marriage has everything to do with men and women, husbands and wives, mothers and fathers and children, and that is why principle-based policy has defined marriage as the union of one man and one woman.

Marriage must be color-blind, but it cannot be gender-blind. The color of two people’s skin has nothing to do with what kind of marital bond they have. However, the sexual difference between a man and a woman is central to what marriage is. Men and women regardless of their race can unite in marriage, and children regardless of their race need moms and dads. To acknowledge such facts requires an understanding of what, at an essential level, makes a marriage.

And a bit later:

If the law taught a falsehood about marriage, it would make it harder for people to live out the norms of marriage because marital norms make no sense, as matters of principle, if marriage is just intense emotional feeling. No reason of principle requires an emotional union to be permanent or limited to two persons, much less sexually exclusive. Nor should it be inherently oriented to family life and shaped by its demands. This does not mean that a couple could not decide to live out these norms where temperament or taste so motivated them, just that there is no reason of principle to demand that they do so. Legally enshrining this alternate view of marriage would undermine the norms whose link to the common good is the basis for state recognition of marriage in the first place.

Insofar as society weakens the rational foundation for marriage norms, fewer people would live them out, and fewer people would reap the benefits of the marriage institution. This would affect not only spouses, but also the well-being of their children. The concern is not so much that a handful of gay or lesbian couples would be raising children, but that it would be very difficult for the law to send a message that fathers matter when it has redefined marriage to make fathers optional.

And one last one:

In fact, much of this is already occurring. Heritage Foundation Visiting Fellow Thomas Messner has documented multiple instances in which redefining marriage has already become a nightmare for religious liberty.[48] If marriage is redefined to include same-sex relationships, then those who continue to believe the truth about marriage—that it is by nature a union of a man and a woman—would face three different types of threats to their liberty: the administrative state, nondiscrimination law, and private actors in a culture that is now hostile to traditional views.[49]

After Massachusetts redefined marriage to include same-sex relationships, Catholic Charities of Boston was forced to discontinue its adoption services rather than place children with same-sex couples against its principles.[50] Massachusetts public schools began teaching grade-school students about same-sex marriage, defending their decision because they are “committed to teaching about the world they live in, and in Massachusetts same-sex marriage is legal.” A Massachusetts appellate court ruled that parents have no right to exempt their children from these classes.[51]

The New Mexico Human Rights Commission prosecuted a photographer for declining to photograph a same-sex “commitment ceremony.” Doctors in California were successfully sued for declining to perform an artificial insemination on a woman in a same-sex relationship. Owners of a bed and breakfast in Illinois who declined to rent their facility for a same-sex civil union ceremony and reception were sued for violating the state nondiscrimination law. A Georgia counselor was fired after she referred someone in a same-sex relationship to another counselor.[52] In fact, the Becket Fund for Religious Liberty reports that “over 350 separate state anti-discrimination provisions would likely be triggered by recognition of same-sex marriage.”[53]

This article is long and comprehensive. It will take some time to read. It’s includes logical arguments as well as empirical evidence from research – with footnotes. I really recommend taking a look at the article. Even if it takes a long time to read, it will definitely expand your mind to think about why we had a definition of marriage in the first place, and what we would lose by changing that definition. When you debate people who want to redefine marriage, it’s very important to appeal to logical arguments and evidence from studies. Get the conversation away from emotions and instead introduce facts and arguments.

My favorite book on the marriage issue is Ryan Anderson’s “Truth Overruled”. If you don’t have it, I really recommend it.

William Lane Craig explains the purpose of prayer

Lets take a closer look at a puzzle
Lets take a closer look at a puzzle

This is from a recent Q&A from his web site Reasonable Faith.

Here’s the question:

My question is this: what is the point of prayer? Here prayer is defined as an attempt to communicate with God.

God either can read our thoughts or he cannot. If he can read our thoughts, there is surely no need to try to transmit or broadcast them to him as he already knows what they are. If he cannot read our thoughts, then any thought-based effort to contact him is futile. It doesn’t matter what type of prayer it is (eg petition, thanksgiving, repentance), there is no point in making any effort to send it up to him.

Of course, Christianity generally holds that God is omniscient and therefore able to read our thoughts, so the first of these scenarios would be the applicable one. The characteristic of omniscience makes the concept of prayer all the more redundant as it means God already knows any information that might be communicated to him, and exactly what the best thing is to do about it, so prayer could not in any way influence his decisions.

I am well aware that the Bible commands us to pray in numerous instances, but in the light of this argument this strikes me as an incredibly arbitrary thing for a good God to command, and thus makes the reliability of the Bible all the more questionable to me.

Currently it seems to me that the idea of prayer is most sensibly explained as an addictive placebo that gives people a greater sense of control over their circumstances than they actually have.

Dr. Craig’s response is long, but here is the key part:

Yes, God can read our thoughts. So how is that problematic for the spiritual discipline of prayer? You say, “there is surely no need to try to transmit or broadcast them to him as he already knows what they are.” Hold on, Joe! Seriously, do you think prayer is a matter of providing God information? You defined prayer as communication with God. You don’t communicate with another person through a third-person relationship. You enter into what has been called an “I-thou” relationship. You speak to another person, not just about that person. Your girlfriend or wife would be decidedly unimpressed if you rationalized never telling her “I love you” on the grounds that she already knows that! Anybody that obtuse is on his way to a break-up! Two people who are in love with each other want to speak to each other, to build an intimate relationship with each other.

So, sure, God reads my mind, and that enables me to pray to Him at any moment, even when audible prayers would be inappropriate. I can shoot up a thought-prayer, “Thank you, Lord!” or “God, give me wisdom!” at a moment’s notice. This is what people in a relationship do. Can you imagine anyone so obtuse as to say, “I don’t have to thank John for what he did for me because he already knows I’m grateful”? Or “I don’t have to apologize to Susan because she already knows I’m sorry”?

Moreover, did it not occur to you that such personal communication may be good for you? I-thou relationships open you up as a person, to make you a more loving, transparent, and vulnerable person. Prayer to God is the same way. God knows what is good for us and so wants us to talk to Him.

But in addition to that – yes, God can answer prayers:

You have a second, different objection to prayer: “omniscience makes the concept of prayer all the more redundant as it means God already knows any information that might be communicated to him, and exactly what the best thing is to do about it, so prayer could not in any way influence his decisions.” This is an objection to the efficacy of prayer. What the objection overlooks is that God can take prayers (or the lack thereof) into account in His providential planning of the world. Knowing that Joe would freely pray in a certain set of circumstances, God may actualize a world in which Joe’s prayers are answered; but had God known that Joe would not pray, God may have actualized something else instead. Prayers, then, are not an effort to change God’s mind. Rather God takes account of prayers in choosing which world to actualize. Prayers thus make a counterfactual difference: if I were not to pray, then something else would have been the case instead. Knowledge of this sort is called “middle knowledge,” and there’s a lot on this website about this fascinating topic.

I have to tell you that in a poll of some of my male apologist friends, we all struggle with prayer. I can’t say why they struggle with prayer, but in my case it’s just that I have trouble understanding how big God is and how much more he can do – especially when there are so many problems and I can’t work on them all myself. My personality is very practical. If something needs to be done, I do it. If something needs to be said, I say it. The best thing to do when any dragon appears is to attack it. The best thing to do when a princess is in distress is to rescue her. I do not call for help when there is anything for me to do. Prayer is like a last resort!

Having said that, I do understand that God wants to partner with me and that means that my perception of him changes as I work my way through the standard prayer practices… acknowledging who God is, thanking him for what I have, asking him for what I need, asking him to defend himself and act to make people aware of him and his character, etc. I do struggle with it, though. It’s not as easy for me to do as go to church or read the Bible. Apologetics, of course, is no problem for me! I wish someone would encourage me to pray.

I think the middle knowledge point he raised is key, though – God, prior to creating the world can factor in all of your prayers that you freely pray, because he foreknows everything you will do in the circumstances (time and place) that he places you in. So, have confidence. Even if he doesn’t answer you the way you expect, your prayers were heard.

Aside from all that, I do think that God is pleased when I pray about my concerns to him. It shows him how I am changing, and have his priorities in my mind, and not my own. If you are interested in pleasing God, then talking to him about your concerns and priorities is a good thing to do, especially as your concerns and priorities become more like his.
