The Fine-Tuning Argument for God’s Existence, Part One

A while back on this web site I posted a series in which I debated with myself about the existence of God. “Pastor Chris” and “Dr. Schriner” argued about various aspects of this topic, including the claim that the laws of the universe are fine-tuned for intelligent life. Continue reading

The Pastor Strikes Back

My recent posts are based on a presentation I sometime make in which “Pastor Chris” debates “Dr. Schriner” about whether God exists. (I take both sides, wearing an ecclesiastical stole when Pastor Chris speaks.) So here is the pastor once again:

How sad that such a smart fellow as Dr. Schriner has to fall back on such outdated atheistic ideas. It is so “Twentieth Century” to proclaim that the grand march of science is closing every gap in our knowledge. Today new discoveries are opening up astonishing new mysteries! At one time we had no idea that the laws of nature are fine-tuned for the existence of life. Not all scientists have realized this is so, but it is revolutionary to hear brilliant physicists say the cosmos seems precisely designed to make our existence possible. Schriner quotes Bradley Monton to dispute this idea, but Monton himself is an atheist, so he’s hardly unbiased! Continue reading

More from the Atheist

This is the third post in a series in which I debate with myself about whether God exists. Skeptical “Dr. Schriner” has just spoken, and now the atheist gets to speak again. Why? Because in a debate, the negative side has an inherent advantage. It’s almost always easier to poke holes in some theory than to prove that this theory is true. To compensate for this handicap, the affirmative side needs some compensating advantage. One way to do this is to let the affirmative begin and end the contest. It’s very helpful to have both the first word and the last word on some topic. To make this possible, Dr. Schriner, who denies the existence of deity, makes his initial presentation and his first rebuttal in sequence, one after the other.

Returning to the lectern, Dr. R. C. Schriner will offer his first negative rebuttal:

Pastor Chris thinks the laws of the universe are “fine-tuned” to support intelligent life. But physicists say there may be other universes, perhaps even an infinite number of universes. Only a few of these systems might happen to be suitable homes for living creatures. If these creatures didn’t know about all the other universes, it would seem as if “the” universe was specifically designed for their benefit. “Wow, how come everything is arranged so precisely for dear little me? I guess there must be a God!” These creatures would be very lucky to live in a cosmos that supports life, but someone has to live there and be amazed at their good fortune. Besides, the fine-tuning argument is speculation on top of speculation, because we still have so much to learn about cosmology. Continue reading

Making the Case for Atheism

In my posts of October 6 and 14, I described a recent presentation in which I argued for both sides of the proposition, Resolved: That a personal deity created the universe. “Personal deity” was defined as a God who does things persons do, such as thinking, feeling, and communicating.

I began by assuming the role of Pastor Chris (Chris is my nickname) and in last week’s blog I quoted some of the Pastor’s remarks. I responded to them in the role of the atheist, Dr. Schriner. Here’s what he said:

This morning I will show that there are no sound reasons for believing in an invisible cosmos-creator, and that there are good reasons to reject this theory. And my first argument is simple. The concept of God is superfluous. People used to explain everything they didn’t understand by saying God did it, but this gives us a “god of the gaps.” As the gaps in our knowledge keep getting smaller, there is less and less reason for the God-hypothesis.

But even beyond this obvious point, I want to make a more daring claim. We can tell that there is no personal God by looking at the behavior of those who believe in God.

Pastor Chris based a lot of his case on the testimony of those who say they talk with God. So consider the possibility that God does communicate with us. If that’s so, then presumably this communication would be helpful to those who receive it. They would become wiser and better human beings than atheists and others who do not receive God’s messages. But that’s not so.

Are Christians, for example, wiser than atheists? Christians say God has revealed hidden truths to them which they could never have discovered by themselves. But Christianity has fragmented into over 30,000 denominations, repeatedly splitting over – guess what? – disagreements about what God is telling them! Rather than hearing clear messages, theists are projecting their own fantasies and prejudices onto a great blank screen in the sky.

What’s worse, these alleged communications do not make believers better persons. Of course some religious people are saintly, but so are some atheists. And church history reveals the wickedness of religious organizations – church leaders burning heretics alive, stirring up witch-hunts, and fomenting “holy” wars. Even today religion fans the flames of inter-group conflict.

You’d think that those who give their whole lives to religion would become especially good people, but we now know that the priesthood of a prominent American denomination was for many years a haven for sexual predators. I trust that those priests were praying every day, but they kept right on abusing children.

Here’s another shocking discovery. According to psychologist of religion David Wulff, researchers have found a correlation between membership in Christian churches and “ethno-centrism, authoritarianism, dogmatism, … rigidity, intolerance of ambiguity, and … prejudice, especially against Jews and blacks.” (Cited by William R. Murry, Reason and Reverence, p. 118.) The more traditionally religious you are, the more prejudiced you are likely to be! Stanford chaplain Scotty McLennan offers “evidence that religion is itself a root cause of conflict and violence.” In giving us a sense of identity, it divides us into in-groups and out-groups, so it intensifies people’s viciousness instead of reforming them.

If churchgoers show no evidence that their spiritual life is making them better persons, how can we believe their testimony that God is speaking to them? Suppose I tell you that I exercise every day in an invisible gymnasium in my house. Even if I managed to convince you that a gym could be invisible, wouldn’t you be skeptical of my claim if you noticed that I was getting weaker instead of stronger?

If God doesn’t communicate with us, God probably does not exist. But if people do receive divine communications, that should make them wiser and better, and it does not. Closely examining the claim that God communicates actually undermines the case for deity.

Another point: My worthy opponent thinks the laws of nature are “fine-tuned” to support the presence of intelligent life. But physicists say there may be other universes, perhaps even an infinite number of universes. Only a few of these systems might happen to be suitable homes for living creatures. If these creatures didn’t know about all the other universes, it would seem as if “the” universe was specifically designed for their benefit. “Wow, how come everything is arranged so precisely for me? I guess there must be a God!”

Furthermore, this claim that even tiny changes in the laws of nature would eliminate all life is actually controversial. Maybe natural laws could vary a lot and still support life. In his book, Seeking God in Science, Philosopher Bradley Monton reports that physicists disagree about fine-tuning. We have no idea whether most of them would agree with the fine-tuning theory or disagree.

In saying we need God, the Reverend resorted to a flippant comment about atheism having no explanation for how matter “magically rearranged itself … into dinosaurs.” Well obviously SOMETHING basic and wondrous did happen for no reason. Either matter exists for no reason, or God exists for no reason. People who say God made the universe don’t ask where God came from. They just shrug their shoulders and change the subject. As Steven Wright says, “A conclusion is the place where you got tired of thinking.”

People may get tired of thinking, but science never grows weary of seeking new truth, shrinking gaps in our knowledge, whittling away at the need for the archaic God-hypothesis.


What will Pastor Chris say in response? Tune in next week. And what would you say, if you are a theist? Post a comment and let me know.
