Sure we do. Doubt is a great motivator to read, study, and think more. How do I deal with it? I read, study, and think. I'm interested in what's true and real, not in made-up stuff. So just like anyone in any disciplinary field, when I have doubts and questions I start digging in to figure things out. What makes up my mind is evidence, reason, and becoming convinced of the truth. Hope that helps. We can talk about this more if you want.

Did you guys ever have any intellectual doubt? How did you deal with it? Or what made up your mind?

thanks.
