“In the short span of mortal existence it is impossible for man to explore with thoroughness any considerable part of the vast realm of knowledge. It becomes, therefore, the part of wisdom to direct our efforts to the investigation of the field that promises results of greatest worth. All truth is of value, above price indeed in its place; yet, with respect to their possible application some truths are of incomparable greater worth than others.” James E Talmage, Articles of Faith
