We reply that the immense value of the Union rests also upon the incontrovertible fact (perhaps not widely suspected, but evident enough when looked for) that the system of government of these United States, the mode in which the smaller and larger communities are combined into the great whole, together with the working of all in concert, _comes the nearest of any other political structure to the Creator's method of combining parts into wholes throughout the universe_. Wherever we behold a specimen of the divine creative skill, whether in the mineral, vegetable, animal, or human kingdoms; whether it be a crystal, a tree, a bird, or beast, a man, or a solar system, in all these we observe one universal method of grouping, common to all conditions. This method is that of grouping parts around centres, and several of such groups around larger centres, upward and onward indefinitely; while in living beings, according to their complexity, each individual part, and each individual group of parts with its centre, _is left free to move within its own sphere, yet at the same time is harmonized with the movements of its neighbors through the medium of the common centre_. Every such work of the Creator is an _E pluribus unum_, a one out of many--a unit composed of many diversified parts, exhibiting a marvellous unity, with an equally wonderful variety. Look at yonder tree, examine its parts, leaves, twigs, branches, trunk, all endowed with a common life. Yet each little individual leaf lives and moves freely upon its centre or twig, which is a common centre for many leaves. Many little twigs in their turn, each free to move by itself within a certain limit, are ranged along their common centre, a branch. Many branches cluster around a large one, and all the largest branches in their turn cluster around the common trunk, or great centre supporting the whole fabric. Each leaf and twig and branch contributes its share to the life of the whole tree, and is in turn supported by the general life and circulating sap. All this is repeated with far greater fulness and complexity in the living animal, or in the human body. How numerous are the parts composing a single organ! How many organs go to one system, how many systems, bony, muscular, fibrous, circulatory, nervous, combine to make up the entire body! Then again, all the members of the body move, _within a certain limit_, in perfect independence of all the rest. The finger can move without the hand, the hand can move without the arm, the forearm without the upper arm, the entire arm without any other limb; and yet all the parts of one limb, and all the limbs together, are harmonized in action by the central brain.
