Except that one seeks ignorance under the guise of knowledge and the other accepts where ignorance is and seeks to know more.
If you are alluding that someone who beleives in God is "satisified" with God being the answer to everything and not asking anymore questions, I disagree with that and History has shown that to not be the case.
Believers are always trying to uderstand and "quantify" the nature of God, something far more vast and hard to understand than just the "mere"universe.
Believers also have a thrist for science and knowledge, as in the case of sceintific believers of the past and those in the present.
Sure there has always been an element of "It is enough to know God", or an element that advocated "don't ask", but the truth is, though vocal, they are the minority.
