Choosing between Argument and Discussion

Argument on a matter gives only uncertainties at the end. A solution will not be arrived at easily. An argument often ends with emotional upheaval, and quarrel between the parties involved. But a discussion on the matter exposes the ignorance present in both sides of the parties. It makes them easily accept their ignorance and lets them learn calmly the facts and the realities by themselves, and to arrive at a solution easily and quickly - in a friendly manner.
