Knowledge increases doubt, confidence comes only with the lack of knowledge?
Knowledge increases logical doubts that are good for a learner and not silly and absurd doubts.
I would just like to add up that lack of knowledge leads to low confidence level.
If someone doesn't has knowledge about some topic then how can he/she be confident.
In fact having knowledge brings boldness on our face and moreover on our attitude.
Yeah it is correct to some extent that knowledge increase doubt but logical doubts and not silly doubts that a foolish guy will have.
