Philosophy is not math. There are open-ended questions that are answered in kind with vague, broad answers with no direct advice on solving a problem. This is why pragmatic philosophy branched out of old school philosophy, to give the body of knowledge some function that could be of use to society.
How can you tell that a person giving mystical, somewhat religious philosophical answers is intelligent? For all we know that person is just good with words and those phrases that s/he uses cannot be translated into another language. Philosophy allows a person to be creative. Philosophy is also molded from dissimilar experiences, so no one philosophy is ever ruled as the best way to understand life and its meaning. There is still that gray area of uncertainty. A gray area that an unintelligent person can take advantage of and irrationally argue on the basis of her or his opinion. Philosophy again is not math. It can be structured but some of its fundamental premises could be flawed, either shown by reality or through some fallacy of its own. There is no perfect system of belief.
