Ignorance to knowledge:
People in science fields reach an absolute point, where they absolutely know what they don't know. They can't assume, for each assumption is as weak as nothing unless experimentally confirmed.
People studying humanity have another choice, once encountering the unknown they start to creatively assume and all assumptions have plausible values.
The two ways above, of concrete ignorance and dubious ignornace have their differing affect on our thinking. The person of concrete ignornace, i.e. the more scientific, would experiment in a lab and finally get the result that is confirmed. However... The person of no concrete ignorance (sociologic and humanitarian) would not have such lab, his own lab is the real life. People follow his/her ideas, risking the failiures that they contain. The real life is their lab and unless the experiment is done on people themselves, the results can't be obtained.
Unlike the field of science, in the fields of life; God has revealed his guidance to people so that they don't go astray and misguided. People like Karl Marx, etc. with their various ideologies have inspired people and conspired against the real success of mankind unknowingly.
Unless ignorance is concrete, correct knowledge is unobtainable. Unless people are safe from the experiments of "knowledgeable" people, that knowledge is not useful. If knowledge is not useful it's better to be discarded, and if not discarded then
Two types of leaders:
Two different people with leadership skills. How do we know who guides and who misguides? One approaches on the humble side, and one entices blind pride and self exaltation. The two leaders have their followers. One easily entices, and the other hardly convinces.
The difference between the two types of leaders can be seen in the example of Moses, with his simplicity, standing infront of the proud and self exalted Pharoah with his luxuries. The encounter of reasoning and pride and misguidance is obvious enough to show the contrast.
