The frivolous make themselves merry with the Ideal theory, if its consequences were burlesque; as if it affected the stability of nature. It surely does not. God never jests with us, and will not compromise the end of nature, by permitting any inconsequence in its procession. Any distrust of the permanence of laws, would paralyze the faculties of man. Their permanence is sacredly respected, and his faith therein is perfect. The wheels and springs of man are all set to the hypothesis of the permanence of nature. We are not built like a ship to be tossed, but like a house to stand. It is a natural consequence of this structure, that, so long as the active powers predominate over the reflective, we resist with indignation any hint that nature is more short-lived or mutable than spirit. The broker, the wheelwright, the carpenter, the toll-man, are much displeased at the intimation.

But whilst we acquiesce entirely in the permanence of natural laws, the question of the absolute existence of nature still remains open. It is the uniform effect of culture on the human mind, not to shake our faith in the stability of particular phenomena, as of heat, water, azote; but to lead us to regard nature as a phenomenon, not a substance; to attribute necessary existence to spirit; to esteem nature as an accident and an effect.

To the senses and the unrenewed understanding, belongs a sort of instinctive belief in the absolute existence of nature. In their view, man and nature are indissolubly joined. Things are ultimates, and they never look beyond their sphere. The presence of Reason mars this faith. The first effort of thought tends to relax this despotism of the senses, which binds us to nature as if we were a part of it, and shows us nature aloof, and, as it were, afloat. Until this higher agency intervened, the animal eye sees, with wonderful accuracy, sharp outlines and colored surfaces. When the eye of Reason opens, to outline and surface are at once added, grace and expression.
