Sticking with my "argument from incredulity" theme for the day...
Jonathan writes:
If you put two naked men in the forrest and one with shaved eyebrows is it fair to say that the one without is at a disadvantage? Come on now, lets be realistic.
Gene replies:
Yes. We've already mentioned three different purposes for eyebrows, that is more than enough to demonstrate reproductive advantage.
The argument from incredulity is only valid prior to the introduction of evidence. Once evidence has been introduced the original argument from incredulity is invalid. You can express incredulity at the evidence, but it is no longer valid to continue to approach the original argument with incredulity. In a debate based upon evidence, "Oh come now" and "Right" don't really have much of a role.
