that the same beauty of form and substance, the same perfection of character, could not be generated without the impressions of disapprobation which arise from the spectacle of moral evil.
When the mind has been awakened into activity by the passions, and the wants of the body, intellectual wants arise; and the desire of knowledge, and the impatience under ignorance, form a new and important class of excitements. Every part of nature seems peculiarly calculated to furnish stimulants to mental exertion of this kind, and to offer inexhaustible food for the most unremitted inquiry. Our mortal Bard says of Cleopatra:
Custom cannot stale Her infinite variety.
The expression, when applied to any one object, may be considered as a poetical amplification, but it is accurately true when applied to nature. Infinite variety seems, indeed, eminently her characteristic feature. The shades that are here and there blended in the picture give spirit, life, and prominence to her exuberant beauties, and those roughnesses and inequalities, those inferior parts that support the superior, though they sometimes offend the fastidious microscopic eye of short-sighted man, contribute to the symmetry, grace, and fair proportion of the whole.
The infinite variety of the forms and operations of nature, besides tending immediately to awaken and improve the mind by the variety of impressions that it creates, opens other fertile sources of improvement by offering so wide and extensive a field for investigation and research. Uniform, undiversified perfection could not possess the same awakening powers. When we endeavour then to contemplate the system of the universe, when we think of the stars as the suns of other systems scattered throughout infinite space, when we reflect that we do not probably see a millionth part of those bright orbs that are beaming light and life to unnumbered worlds, when our minds, unable to grasp the immeasurable conception, sink, lost and confounded, in admiration at the mighty incomprehensible power of the Creator, let us not querulously complain that all climates are not equally genial, that perpetual spring does not reign throughout the year, that God's creatures do not possess the same advantages, that clouds and tempests sometimes darken the natural world and vice and misery the moral world, and that all the works of the creation are not formed with equal perfection. Both reason and experience seem to indicate to us that the infinite variety of nature (and variety cannot exist without inferior parts, or apparent blemishes) is admirably adapted to further the high purpose of the creation and to produce the greatest possible quantity of good.
The obscurity that involves all metaphysical subjects appears to me, in the same manner, peculiarly calculated to add to that class of excitements which arise from the thirst of knowledge. It is probable that man, while on earth, will never be able to attain complete satisfaction on these subjects; but this is by no means a reason that he should not engage in them. The darkness that surrounds these interesting topics of human curiosity may be intended to furnish endless motives to intellectual activity and exertion. The constant effort to dispel this darkness, even if it fail of success, invigorates and improves the thinking faculty. If the subjects of human inquiry were once exhausted, mind would probably stagnate; but the infinitely diversified forms and operations of nature, together with the endless food for speculation which metaphysical subjects offer, prevent the possibility that such a period should ever arrive.
