God had said to listen to what five people tell you and don’t hold on to your own opinion. The person who holds on to his opinion is isolated. If you insist upon it, it will harm you as well as others. This true-false is a relative truth; it is a mundane [worldly] truth. One should not insist upon it.
If all meaning were relative, then the meanings of the terms in the proposition "All meaning is relative" would be relative. Therefore the proposition "All meaning is relative" destroys itself. It is nothing but an evasion of reality. That seems a high price to pay, even for the privilege of killing people.
