Of politics, foreign and domestic, he talked frequently, but always philosophically and dispassionately, much as if he were speaking of geological stratification. His views of humanity were deduced from a most extensive survey of the race in all its historical and geographical relations. He distinctly recognized the fact of its steady advance from one stage to another, in accordance with a plan of intellectually organic development, as marked as that detected by the geologist in the gradual preparation of the earth for the abode of our species. The slowness and seeming vacillation of man's upward movement could not stagger his faith; for if it had taken thousands of ages to make earth habitable, why should it not take thousands more to bring man to his completeness? Equally free was he from misgiving on account of the remaining presence of so much misery and wretchedness; for these he considered as the indispensable stimuli to progress. Even war, he used to say, is sometimes necessary to the welfare of nations, as sickness and sorrow plainly are to that of individuals; although, to his moral sense, the human authors of this scourge were no more admirable than the devisers of any private calamity. Improvements in knowledge he regarded as the only elements of real progress; and these he looked upon as true germinal principles, bound up organically in the constitution of the human soul. Indeed, that philosophical calmness which was characteristic of him seemed to flow in some measure from his settled persuasion that the same matchless wisdom and benevolence he recognized throughout Nature wrought with a still higher providence and a more earnest love for man and would make all things finally conduce to his welfare. It was clear that he drew a profound tranquillity from the thought that he was a part of the vast and harmonious whole. Concerning his religious views he was exceedingly taciturn. He had no taste for metaphysical or theological discussions, although his library contained a large number of standard works on these subjects. Religion itself he never alluded to but with the deepest respect. Talking to me of Christianity, he quoted the observation of Goethe, that "it had brought into the world a light never to be extinguished." He spoke of Jesus with poetic, if not with Christian fervor. He contrasted his teachings and deeds with the prevailing maxims and practice of the people among whom he appeared, with the dead orthodoxy of its religious teachers, and with the general ignorance and hypocrisy of the masses. "Had I lived in such a state of society," he said, "I am certain that it would have driven me mad."
