A person who argues should not be given knowledge. An argumentative mind is not receptive to knowledge. When someone is in an argumentative mood, then giving knowledge or advice is in vain. In an argumentative mood you feel you know it all. Then you are not ready for knowledge. That is why wise people do not give advice when they are in an argumentative environment.
Argument has a purpose. It can bring out the truth if there is no emotion or sense of "I" attached to it. Argument can also have a disadvantage. It can make untruth appear to be truth. A wise man will not take arguments seriously; he will just have fun with them. Wisdom is beyond all arguments.
