On April 9th there was a Christian/atheist debate at Portland State University entitled "Does anything supernatural exist?" that was sponsored by the PSU Freethinkers' student group. The Christian was Phil Smith, a philosophy professor at George Fox University. The atheist was Bernie Dehler, who is a former born-again evangelical Christian and participates in many local area debates.

Phil's presentation included the idea that there are non-natural things that exist, such as morality. He posits that morality is not a material/natural thing, and therefore belongs in some other realm.
One of Bernie's main ideas was to establish the difference between "scientific thinking" and "magical thinking." Humans have a history of trying to explain natural events (such as earthquakes) with magical and supernatural causes. Scientific thinking, combining scientific facts with logical thinking, is the antidote to magical thinking. Sometimes science teaches us things that go against common sense (such as the geocentric view of the solar system vs. an incorrect geocentric model which seems to make more sense to us from our limited visual perspectives).
"Science is simply common sense at its best, that is, rigidly accurate in observation, and merciless to fallacy in logic." ~Thomas Huxley, an English biologist, known as "Darwin's Bulldog" for his advocacy of Charles Darwin's theory of evolution.
