Communication is Essential!

Rule Two: The Truth-Seeking Principle.

Each participant should be committed to the task of earnestly searching for the truth, or at least the most beneficial solution for those involved. This means that one should be willing to examine alternative positions seriously, look for insights in the positions of the other, and allow the other participant to present arguments for or raise objections to any position raised on the issue (Attacking Faulty Reasoning pg.10).
The truth seeking principle goes hand in hand with the fallibility principle.
Socrates taught; "We come to true knowledge only by first recognizing our own ignorance or lack of knowledge."
We know that the search for truth is a life-long endeavor, and that is certainly true in our eternal relationships. If we really want to find the truth in our relationships concerning the issues that arise, it is imperative not only that we assume that we may not have the truth, (or the "right" answer; the fallacy principle) but that we listen to the other person for alternative positions and encourage questions and clarity about our own positions.

In Jacob 4:10 we are given some good insight to the spirit of this truth-seeking principle. "Seek not to counsel the Lord, but to take counsel from His hand. For behold ye yourselves know that he counseleth in WISDOM, and in JUSTICE, and in great MERCY, over all his works."

We need to follow Christ's example and seek counsel at the hands of each other in the same fashion; with wisdom, justice and mercy.
As flawed humans we have a tendency to want to possess only those opinions, ideas and ways of doing things that are "right" or "true", but the satisfaction of that interest comes at a price...a willingness to look at all available options, and the arguments that support those other options. If we are not willing to do this, then we might miss the truth completely. The problem is, when we enter into a discussion on an issue, we all want the opinions we hold to be the truth.

Real truth-seekers do not try to win by ignoring or denying the counterevidence against their positions. A genuine win comes from following the rules of the game. Pronouncing yourself the winner before the game has started, or by refusing to play by the rules fails to advance the search for a congenial solution and is, in the end, self defeating.
