In many ways this constancy of Lincoln rewards attentive thought. For one thing, it was radiant with intelligence. Indeed in him the two became identified. As thus conceived, it shows as pure and clear consistency. His fully tried reliability was the well-poised balance of a mind long-schooled in the art of steadiest deliberation. When Lincoln held immutably fast, it was due to his invincible faith that the conviction to which he clung involved abiding truth. This quality tempered all his firmness. Just here one finds the genesis and motive of all his skilled invention of reasoned, pleading speech. Lincoln's prevailing power of urgent argument roots in the deep persistency of his convinced belief. It was because of an impassioned confidence, an assurance that was vibrant with a note of triumph, that his grasp of any ruling purpose was so unwaveringly firm. This was his mood and attitude in all the major contentions of his life. To the central tenets that those contentions involved he held with all the firmness of the rooted hills. Touching those primary principles in his character and politics his mind and faith seem to have attained an absolute confirmation. And from those settled positions he could never be moved. Constancy in him was nothing more nor less than the energetic affirmation of intellectual rectitude. His steadfastness, thus, was a mental poise. It can be defined as ripened judgment, a conclusion of thought, safeguarded on every side by a discernment not easily confused, by a penetration not easy to escape. This involved a wonderful flexibility. While steadfast unto the grade of immutability, where honor was involved, no student of his ways could call him obstinate. While firm and strong enough to hold the Nation to her predestined course upon an even keel, he held her helm with a gentle, pliant grasp. Being in every mental trait inherently honest and deliberate, he could at once be resolute and free. This blend within his being of thoughtfulness and determination, of openness and immutability, this candid, conscientious, mental poise, this Godlike apprehension of the larger equilibrium, qualified him peculiarly to interpret the major movements of his time, to trace in the deep, prevailing sentiments of the human soul the chart of our national destiny.
