What argument is most convincing to plant the seeds of doubt (or, rather, faith) in an atheist’s mind?
Do you mind if I restate your question while retaining its original intent? It might be more interesting to phrase it this way: Atheists on this site have kindly submitted questions for me, but what questions would I ask an atheist?
As I pondered that issue, I decided to send emails to some of my friends to get advice on what they would ask. Here are a few of their replies — all of which I agree would be excellent to ask a skeptic. If they’re considered fully with all of their implications, they might indeed plant some seeds:
Historian Gary Habermas: “Utilizing each of the historical facts conceded by virtually all contemporary scholars, please produce a comprehensive natural explanation of Jesus’ resurrection that makes better sense than the event itself.”
These historical facts are: (1) Jesus was killed by crucifixion; (2) Jesus’ disciples believed that he rose and appeared to them; (3) The conversion of the church persecutor Saul, who became the Apostle Paul; (4) the conversion of the skeptic James, Jesus’ half-brother; (5) The empty tomb of Jesus. These “minimal facts” are strongly evidenced and are regarded as historical by the vast majority of scholars, including skeptics, who have written about the resurrection in French, German, and English since 1975. While the fifth fact doesn’t have quite the same virtual universal consensus, it nevertheless is conceded by 75 percent of the scholars and is well supported by the historical data if assessed without preconceptions.
Philosopher Paul Copan: “Given the commonly recognized and scientifically supported belief that the universe (all matter, energy, space, time) began to exist a finite time ago and that the universe is remarkably finely tuned for life, does this not (strongly) suggest that the universe is ontologically haunted and that this fact should require further exploration, given the metaphysically staggering implications?
“And, second, granted that the major objection to belief in God is the problem of evil, does the concept of evil itself not suggest a standard of goodness or a design plan from which things deviate, so that if things ought to be a certain way (rather than just happening to be the way they are in nature), don’t such ‘injustices’ or ‘evils’ seem to suggest a moral/design plan independent of nature?”
Talk show host Frank Pastore: “Please explain how something can come from nothing, how life can come from non-life, how mind can come from brain, and how our moral senses developed from an amoral source.”
Historian Mike Licona: “Irrespective of one’s worldview, many experience periods of doubt. Do you ever doubt your atheism and, if so, what is it about theism or Christianity that is most troubling to your atheism?”
Author Greg Koukl: “Why is something here rather than nothing here? Clearly, the physical universe is not eternal (Second Law of Thermodynamics, Big Bang cosmology). Either everything came from something outside the material universe, or everything came from nothing (Law of Excluded Middle). Which of those two is the most reasonable alternative? As an atheist, you seem to have opted for the latter. Why?”
I didn’t email Alvin Plantinga, considered by many to be among the greatest philosophers of modern times. But based on his assertion that naturalism is self-defeating, we could formulate this question (thanks to William Lane Craig for some of the concise wording): If our cognitive faculties were selected for survival, not for truth, then how can we have any confidence, for example, that our beliefs about the reality of physical objects are true or that naturalism itself is true? (By contrast, theism says God has designed our cognitive faculties in such a way that, when functioning properly in an appropriate environment, they deliver true beliefs about the world.)
Granting these questions their full weight, and doing your best to set aside bias and preconceptions, how would you answer them?
