“We have been blessed with much knowledge by revelation from God which, in some part, the world lacks. But there is an incomprehensibly greater part of truth which we must yet discover. Our revealed truth should leave us stricken with the knowledge of how little we really know. It should never lead to an emotional arrogance based upon a false assumption that we somehow have all the answers–that we in fact have a corner on truth, for we do not.”

Hugh B. Brown, “An Eternal Quest – Freedom of the Mind,” speech given to the BYU student body on May 13, 1969
