Fred Clark has a great post on magic tricks and the art of debate, which he starts off by saying ““Debate” is a parlor trick.” Here is a sample:
When Ray Comfort challenges someone to a debate over the truth of Christianity, I wince because I am a Christian and I know that Comfort is most likely going to “lose” that debate, leading some to the mistaken conclusion that this indicates something meaningful about the truth or untruth of what I believe. When William Lane Craig challenges someone to a debate over the truth of Christianity, I wince because I am a Christian and I know that Craig is most likely going to “win” that debate, leading some to the mistaken conclusion that this indicates something meaningful about the truth or untruth of what I believe…
“Debate” can carry you only until you encounter a situation in which your tricks don’t matter. Or until you encounter someone who knows better tricks than you do.
