Dr. Walter L. Bradley (C.V. here) is the Distinguished Professor of Engineering at Baylor, and a great example of the integration of Christian faith and a stellar academic career. He is not a “secret-service” Christian. Rejecting the notion of safe, private Christianity, he instead projects his Christian faith outward, where his students and colleagues can be aware of his beliefs.

Below I analyze a lecture I chose from the hundreds of public lectures he has given all over the world on the integration of Christian faith with other public, testable areas of knowledge. In this lecture, entitled “Is There Scientific Evidence for an Intelligent Designer?“, Dr. Bradley explains how the progress of science has made the idea of a Creator and Designer of the universe more acceptable than ever before.

Evidence #1: The design of the universe

1. The correspondence of natural phenomena to mathematical law

  • All observations of physical phenomena in the universe, such as throwing a ball up in the air, are described by a few simple, elegant mathematical equations.

2. The fine-tuning of physical constants and rations between constants in order to provide a life-permitting universe

  • Life has certain minimal requirements; long-term stable source of energy, a large number of different chemical elements, an element that can serve as a hub for joining together other elements into compounds, etc.
  • In order to meet these minimal requirements, the physical constants, (such as the gravitational constant), and the ratios between physical constants, need to be withing a narrow range of values in order to support the minimal requirements for life of any kind.
  • Slight changes to any of the physical constants, or to the rations between the constants, will result in a universe inhospitable to life.
  • The range of possible ranges over 70 orders of magnitude.
  • Although each individual selection of constants and ratios is as unlikely as any other selection, the vast majority of these possibilities do not support the minimal requirements of life of any kind. (In the same way as any hand of 5 cards that is dealt is as likely as any other, but you are overwhelmingly likely NOT to get a royal flush. In our case, a royal flush is a life-permitting universe).

Examples of finely-tuned constants and ratios: (there are more examples in the lecture)

a) The strong force: (the force that binds nucleons (= protons and neutrons) together in nucleus, by means of meson exchange)

  • if the strong force constant were 2% stronger, there would be no stable hydrogen, no long-lived stars, no hydrogen containing compounds. This is because the single proton in hydrogen would want to stick to something else so badly that there would be no hydrogen left!
  • if the strong force constant were 5% weaker, there would be no stable stars, few (if any) elements besides hydrogen. This is because you would be able to build up the nuclei of the heavier elements, which contain more than 1 proton.
  • So, whether you adjust the strong force up or down, you lose stars than can serve as long-term sources of stable energy, or you lose chemical diversity, which is necessary to make beings that can perform the minimal requirements of living beings. (see below)

b) The conversion of beryllium to carbon, and carbon to oxygen

  • Life requires carbon in order to serve as the hub for complex molecules, but it also requires oxygen in order to create water.
  • Carbon is like the hub wheel in a tinker toy set: you can bind other elements together to more complicated molecules (e.g. – “carbon-based life), but the bonds are not so tight that they can’t be broken down again later to make something else.
  • The carbon resonance level is determined by two constants: the strong force and electromagnetic force.
  • If you mess with these forces even slightly, you either lose the carbon or the oxygen.

3. Fine-tuning to allow a habitable planet

  • A number of factors must be fine-tuned in order to have a planet that supports life
  • Initial estimates predicted abundant life in the universe, but revised estimates now predict that life is almost certainly unique in the galaxy, and probably unique in the universe.
  • Even though there are lots of stars in the universe, the odds are against any of them supporting complex life.
  • Here are just a few of the minimal requirements for habitability: must be a single star solar system, in order to support stable planetary orbits, the planet must be the right distance from the sun in order to have liquid water at the surface, the planet must sufficient mass in order to retain an atmosphere, etc.

The best current atheist response to this is to speculate that there may be an infinite number of unobservable and untestable universes. (I.e. – the Flying Spaghetti Monster did it)

Evidence #2: The origin of the universe

1. The progress of science has shown that the entire physical universe came into being out of nothing (= “the big bang”). It also shows that the cause of this creation event is non-physical and non-temporal. The cause is supernatural.

  • Atheism prefers an eternal universe, to get around the problem of a Creator having to create the universe.
  • Discovery #1: Observations of galaxies moving away from one another confirms that the universe expanded from a single point.
  • Discovery #2: Measurements of the cosmic background radiation confirms that the universe exploding into being.
  • Discovery #3: Predictions of elemental abundances prove that the universe is not eternal.
  • Discovery #4:The atheism-friendly steady-state model and oscillating model were both falsified by the evidence.
  • And there were other discoveries as well, mentioned in the lecture.

The best atheistic response to this is to speculate that there is an unobservable and untestable hyper-universe outside our own. (I.e. – the Flying Spaghetti Monster did it)

Evidence #3: The origin of life

1. The progress of science has shown that the simplest living organism contains huge amounts of biological information, similar to the Java code I write all day at work. This is a problem for atheists, because the sequence of instructions in a living system has to come together all at once, it cannot have evolved by mutation and selection – because there was no replication in place prior to the formation of that first living system!

  • Living systems must support certain minimum life functions: processing energy, storing information, and replicating.
  • There needs to be a certain amount of complexity in the living system that can perform these minimum functions.
  • But on atheism, the living system needs to be simple enough to form by accident in a pre-biotic soup, and in a reasonable amount of time.
  • The minimal functionality in a living system is a achieved by DNA, RNA and enzymes. DNA and RNA are composed of sequences of proteins, which are in turn composed of sequences of amino acids.

Consider the problems of building a chain of 100 amino acids

  • The amino acids must be left-handed only, but left and right kinds are equally abundant in nature. How do you sort out the right-handed ones?
  • The amino acids must be bound together using peptide bonds. How do you prevent other types of bonds?
  • Each link of the amino acid chain needs to be carefully chosen such that the completed chain with fold up into a protein. How do you choose the correct amino acid for each link from the pool of 20 different kinds found in living systems?
  • In every case, a human or other intelligence could solve these problems by doing what intelligent agents do best: making choices.
  • But who is there to make the choices on atheism?

The best current atheistic response to this is to speculate that unobservable and untestable aliens seeded the earth with life. (I.e. – the Flying Spaghetti Monster did it)

The problem of the origin of life is not a problem of chemistry, it is a problem of engineering. Every part of car functionality can be understood and described using the laws of physics and chemistry. But an intelligence is still needed in order to assemble the components into a system that has the minimal requirements for a functioning vehicle.

Conclusion

In all three areas, scientists expected that the data would be consistent with atheism. First, scientists expected that life could exist even if the physical constants and ratios were altered. The progress of science said NO. Second, scientists expected that the universe would be eternal. The progress of science said NO. Third, scientists expected that the origin of life would be simple. The progress of science said NO.

Did God create evil?

Leave a comment

Over at Tough Questions Answered, I found an answer to a question I get all the time:

Now here is a question that many people struggle with.  Here is how the argument generally goes:

  1. God is the Author of everything.
  2. Evil is something.
  3. Therefore, God is the Author of evil.

This is a valid syllogism, meaning that if premises 1 and 2 are correct, then the conclusion follows.

Looking at premise 1, is God the author of everything?  Well, if he isn’t, then we don’t have a sovereign creator, but that’s what the Bible teaches.  We can’t reject this premise.

Looking at premise 2, if we deny that evil exists, then we deny a basic truth about reality.  There clearly is evil in the world and we all know it.  To deny the existence of evil would be to deny a fundamental aspect of life.

Are we stuck?  Not exactly.

Well, go on over there and see what the answer is, I’m not going to tell you.

Atheism, Christianity and the problem of evil and suffering

35 Comments

In Christian theology, a classical definition of evil is found in the work of Augustine of Hippo. He states that the evil is not a thing itself, and therefore is not brought into being by God. Instead, evil is the privation of right order. Or, to put it more simply, evil is the state of affairs when things are the way they ought not to be. So, if a mugger mugs you and steals your money, that was evil, because humans ought not to do that. And if a tsunami leaves thousands of people homeless, that’s evil, because the world ought not to be like that. (Let’s bracket why God might allow natural evil, such as the latter example, for another post).

The point is that when you talk about evil and suffering, it pre-supposes that the world is not the way it ought to be. But that means that the world ought to be some way. If the world “ought to be” any way other than it is, then that pre-supposes a designer, who had a purpose for the world, i.e. – a way the world ought to be.

But that’s not my point today. My point today is that atheists cannot use the apparently gratuitous evil in the world as a disproof that there is a God until they define what they mean by evil.

It seems to me that there are 2 choices for what evil could be on atheism. What is NOT open to atheists is the solution above, namely, that evil is a departure from the way things ought to be. Because the universe is an accident on atheism – it is purposeless – there is no way the universe ought to be. We are accidents on atheism. There is no way we ought to be.

So evil must mean one of two things on atheism:

  1. Evil means something that the atheist finds personally distasteful. It is a subjective preference that each person decides for themselves. Just as some people don’t like broccoli – some people don’t like murder or tsunamis. It’s up to each person. But that cannot be used as an argument against God, because who says that God’s moral purposes ought to be connected to the personal moral preferences of atheists? It won’t work.
  2. Evil is what society says is counter to the social conventions of a particular time and place. If we decide that murder is against our society’s conventions today, then for that time and place, murder is “evil”. But then, not signaling when you turn right at a stop sign is also “evil”. It’s all just made-up conventions. And again, it is difficult to see why God should be bound by a society’s conception of good and evil, they are just conventions of accidental people, on an accidental planet, in an accidental universe. (Again, we will bracket the problem of deciding what a society is for this discussion).

So, now I am going to ask you atheists. When you say that there is gratuitous evil in the world, (i.e. – a state of affairs that is apparently pointless, apparently without morally sufficient justification for God to permit it), what do you mean by evil? Does not the invocation of a standard of right and wrong that applies to God himself imply an objective morality? (a moral standard that is independent of personal or cultural preferences) And if there is an objective moral standard like this, where does it come from, on your atheistic worldview?

It seems to me that pressing the problem of evil is inconsistent on atheism. There is no moral standard to hold God accountable to in an accidental universe. You have to pre-suppose an objective moral standard, and a designer of the universe who makes that standard and makes it applicable, before you can proceed to hold God accountable to that standard. But then, you have already assumed God in order to argue against him.

Here is a short paper that contains a summary of everything I know about the problem of evil, (deductive/ logical, as well as inductive/ probabilistic). If you can only read one short paper on the problem of evil/ suffering, this is what you need to read. Do not pass this paper up – it is pure wisdom and will make you effective on this issue in the public square better than anything else out there.

Also, to see these arguments in action, check out the debate here, with William Lane Craig and Kai Nielsen.  If you want a book, here is one between William Lane Craig and Walter Sinnott-Armstrong, published by Oxford University Press, 2004, (audio of one of their debates here). One of my favorite scholars on this topic is Doug Geivett. If you can listen to the audio from his lecture on evil, that is pure wisdom. It’s up on the Academy of Christian Apologetics, (audio). I love the use of “noseeums” in his examples.

UPDATE:

I was over on triablogue.com, and they were commenting on a post over at Victor Reppert’s blog C.S. Lewis’ Dangerous Idea, on the topic of morality on atheism. Also, there this debate between Douglas Wilson and Christopher Hitchens is fantastic for understanding why morality is irrational on an atheistic worldview.
