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. These proceed from imagination and affection, and abate somewhat of the angular distinctness of objects. If the Reason be stimulated to more earnest vision, outlines and surfaces become transparent, and are no longer seen; causes and spirits are seen through them. The best moments of life are these delicious awakenings of the higher powers, and the reverential withdrawing of nature before its God. Let us proceed to indicate the effects of culture. 1. Our first institution in the Ideal philosophy is a hint from nature herself. Nature is made to conspire with spirit to emancipate us. Certain mechanical changes, a small alteration in our local position apprizes us of a dualism. We are strangely affected by seeing the shore from a moving ship, from a balloon, or through the tints of an unusual sky. The least change in our point of view, gives the whole world a pictorial air. A man who seldom rides, needs only to get into a coach and traverse his own town, to turn the street into a puppet-show. The men, the women,--talking, running, bartering, fighting,--the earnest mechanic, the lounger, the beggar, the boys, the dogs, are unrealized at once, or, at least, wholly detached from all relation to the observer, and seen as apparent, not substantial beings. What new thoughts are suggested by seeing a face of country quite familiar, in the rapid movement of the rail-road car! Nay, the most wonted objects, (make a very slight change in the point of vision,) please us most. In a camera obscura, the butcher's cart, and the figure of one of our own family amuse us. So a portrait of a well-known face gratifies us. Turn the eyes upside down, by looking at the landscape through your legs, and how agreeable is the picture, though you have seen it any time these twenty years! In these cases, by mechanical means, is suggested the difference between the observer and the spectacle,--between man and nature. Hence arises a pleasure mixed with awe; I may say, a low degree of the sublime is felt from the fact, probably, that man is hereby apprized, that, whilst the world is a spectacle, something in himself is stable.
