The publicity of mutual understanding between individuals is a social necessity. If they commit themselves to so, they will have the ability to shoulder the burdens of life and enjoy a peaceful coexistence. It goes without saying that tongue is the instrument of mutual understanding and the translator of the various concepts that rove in people’s minds. It therefore plays a serious role in the existence of communities and the harmony of individuals’ feelings and ideas. The happiness or distress of any society depends upon verbal truthfulness or falsehood. If tongue is truthful in interpreting the emotions, it will fulfill the mission of communication. If it, on the other hand, is characterized by mistranslation and misexpression, it will be the guide t o evil and the means of social destruction. Hence, truth, whose effects and reflections play the greatest role in the individuals’ lives, is a social necessity.
Parties of transactions, for instance, can save themselves and times from the fatigue of bargain if they adhere to truthfulness. If all people observe truthfulness, they will gain its innumerable benefits and advantages. If untruth, on the other hand, be comes a common phenomenon in a society, the moral principals will be
flimsy, mutual understanding will be missing, and the society will be the subject of disarrangement.
