The great predominating elements of Mr. Lincoln's peculiar character, were: First, his great capacity and power of reason; secondly, his excellent understanding; thirdly, an exalted idea of the sense of right and equity; and, fourthly, his intense veneration of what was true and good. His reason ruled despotically all other faculties and qualities of his mind. His conscience and heart were ruled by it. His conscience was ruled by one faculty--reason. His heart was ruled by two faculties--reason and conscience. I know it is generally believed that Mr. Lincoln's heart, his love and kindness, his tenderness and benevolence, were his ruling qualities; but this opinion is erroneous in every particular. First, as to his reason. He dwelt in the mind, not in the conscience, and not in the heart. He lived and breathed and acted from his reason--the throne of logic and the home of principle, the realm of Deity in man. It is from this point that Mr. Lincoln must be viewed. His views were correct and original. He was cautious not to be deceived; he was patient and enduring. He had concentration and great continuity of thought; he had a profound analytic power; his visions were clear, and he was emphatically the master of statement. His pursuit of the truth was indefatigable, terrible. He reasoned from his well-chosen principles with such clearness, force, and compactness, that the tallest intellects in the land bowed to him with respect. He was the strongest man I ever saw, looking at him from the stand-point of his reason--the throne of his logic. He came down from that height with an irresistible and crushing force. His printed speeches will prove this; but his speeches before courts, especially before the Supreme Courts of the State and Nation, would demonstrate it: unfortunately, none of them have been preserved. Here he demanded time to think and prepare. The office of reason is to determine the truth. Truth is the power of reason--the child of reason. He loved and idolized truth for its own sake. It was reason's food.
