lecture or sermon on questioning established theory

I heard a sermon or lecture a while back, I think it might have been by the Christian pastor Voddie Baucham or someone similar. It had to do with the necessary prerequisites that needed to be satisfied in order to then contest a well established theory. This would be in the context of questioning the philisophical or scientific claims of the majority.

I heard this lecture, and then lost it. Been looking for it ever since. Does anyone know of this sermon or anything like it?

This probably is not the lecture you saw, but if you have never heard this man, you may want to hear more from him;

I Love Greg Bahnsen, what an excellent teacher in apologetics. I have read many of his articles and I am still plowing through his wonderful work on Van Til's Apologetic.

Despite the fact that this is not what I was looking for, it does look good! I watched a few minutes of it, and right off the bat I like his solid logical approach. Thanks
