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.
