"In the above cases it will be seen that the process is one of the addition of new forces, with a constant limitation of the field within which the forces act.... It is to be noticed, however, that while the field of each added and superior force is narrowed, yet nothing is dropped. Each lower force shoots through, and combines itself with all that is higher. Because he is rational, man is not the less subject to gravitation and cohesion and chemical affinity. He has also the organic life that belongs to the animal. In him none of these are dropped; _but the rational life is united with and superinduced upon all these_, so that man is not only a microcosm, but is the natural head and ruler of the world. He partakes of all that is below him, _and becomes man by the addition of something higher_.... Here, then, is our model and law. Have we a lower sensitive and animal nature? Let that nature be cherished and expanded by all its innocent and legitimate enjoyments, for it is an end. But--and here we find the limit--let it be cherished _only as subservient to the higher intellectual life_, for it is also a means." The italics are ours. Satisfactory, true, and self-sustained as is this theory,--and it is one which like a granite Gothic spire lifts itself high and calm into the atmosphere, standing firm and immovable in its own clear and self-evident truth, unshaken by a thousand assaulting materialistic storms,--we would buttress it with the utterances of other of the earth's noble ones; and this we do not because it is in any degree needful, but because our mind loves to linger round the theme, and to gather the concurrent thought of various rarely endowed minds upon this subject. Exactly in point is the following--one of many passages which might be selected from the works of that profoundest of English metaphysicians and theologians, S. T. Coleridge:--
