How would knowledge conquer doubt and fear?
No way, in isolation! Only when COUPLED with wisdom, doubt & fear can be conquered. There are very many knowledgeable persons. And many amongst them develop more of unfounded doubts & fear too, due to sheer magnitude of knowledge they possess! Once they get some wisdom, they evolve, and then USE their knowledge just as a reference, at will, and consciously(and not helplessly trapped in it!) yes! A very good question indeed!
