How to consult, and seeking the “opinion of a wise, sagacious man”

… consultation must have for its object the investigation of truth. He who expresses an opinion should not voice it as correct and right but set it forth as a contribution to the consensus of opinion; for the light of reality becomes apparent when two opinions coincide. A spark is produced when flint and steel come together. Man should weigh his opinions with the utmost serenity, calmness and composure. Before expressing his own views he should carefully consider the views already advanced by others. If he finds that a previously expressed opinion is more true and worthy, he should accept it immediately and not willfully hold to an opinion of his own. By this excellent method he endeavors to arrive at unity and truth. Opposition and division are deplorable. It is better then to have the opinion of a wise, sagacious man; otherwise, contradiction and altercation, in which varied and divergent views are presented, will make it necessary for a judicial body to render decision upon the question. Even a majority opinion or consensus may be incorrect. A thousand people may hold to one view and be mistaken, whereas one sagacious person may be right. Therefore, true consultation is spiritual conference in the attitude and atmosphere of love. Members must love each other in the spirit of fellowship in order that good results may be forthcoming. Love and fellowship are the foundation.
