...education is to train the mind to THINK better, indeed the brain which was earlier caller a “cooler” processes the accumulated data, information, knowledge, experience and wisdom to arrive at a conclusion but in an illiterate person though there might be patchy information or experience, generally “short circuits” into a defective conclusion and are often “short tempered” relying more on their instinct (Id) than the “Ego” or the “Super Ego” which comes with more learning and wisdom; many “fuzz factors” need to be taken into consideration before arriving at a decision.

P.S. For an example, the famous equation, E = mc^2 is just a mnemonic devised for easy remembering of a complex reality; actually, the proper equation together with the “fuzz factors” is E^2 = (mc^2 )^2 + (pc)^2
(^ stands for the power). As one progresses in life with learning, tends to THINK more together with more and more “fuzz factors” of life.
