Doesn’t sound like he’s got much faith if he’s so worried that becoming more educated will result in losing faith. If something is true, broadening information generally shouldn’t challenge faith. And if it does, those contradictions would be worthy frontiers for scientific discovery.
There’s a reason why more education results in less faith, and it’s not brain washing (if it was, why hasn’t it been picked apart by now?).
A similar line of reasoning applies to higher education resulting in less conservative beliefs. There’s also a reason why religion and conservative beliefs are closely aligned about this.
