How to express our opinion when consulting

… 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. (The Promulgation of Universal Peace, p. 72)
