_The Theory applied to inorganic Forms._--And first, to begin with the lowest, how is it with the inanimate, inorganic, merely chemical forms of matter? Here we have certain lines, certain figures, certain colors, that we call beautiful. What do they express of the higher or spiritual element of being? In themselves, and directly, they express nothing, perhaps. Yet are they not, after all, suggestive, symbolical of an idea and spirit dwelling, not in them, but in him who made them, of the Creator's idea and spirit, inarticulate expressions, mere natural signs, of a higher principle than dwells in these poor forms? Do they not suggest and express to us ideas of grace, elegance, delicacy, and the like? Do we not find ourselves attracted by, and, in a sort, in sympathy with these forms, as thus significant and expressive? Is it not thus that lines, and figures, and mathematical forms, the regular and sharply cut angles of the crystal, the light that flashes on its polished surface, or lies hid in beautiful color within it, the order, proportion, and movement, by fixed laws, of the various forms of matter, appear beautiful to us? For what are order, proportion, regularity, harmony, and movement, by fixed laws, and what are elegance, and grace of outline and figure, but so many signs and expressions of a higher intelligence? _Theory applied to vegetable Forms._--Passing onward and upward in the scale of being, taking into view, now, the organic forms of vegetable life, do we not find a more definite articulate expression of the spiritual and invisible under the material form? The flower that blooms in our path, the sturdy tree that throws out its branches against the sky, or droops pensively, as if weighed down by some hidden sorrow, address us more directly, speak more intimately to our spirits, than the mere crystal can do, however elegant its form, or definite its outline. They express sentiments, not ideas merely. They respond to the sensibilities, they appeal to the inner life of the soul. They are strong or weak, timid or bold, joyous or melancholy. It requires no vigorous exercise of fancy to attribute to them the sensibilities which they awaken in us. When in lively communion and sympathy with nature, we can hardly resist the conviction that the emotions which she calls into play in our own bosoms are, somehow, her own emotions also; that under these forms so expressive, so full of meaning to us, there lurks an intelligence, a soul.
