yet organized beings, that escape the nicest inquisition of the sense; when we push our discoveries yet downward, and consider those creatures so many degrees yet smaller, and the still diminishing scale of existence, in tracing which the imagination is lost as well as the sense; we become amazed and confounded at the wonders of minuteness; nor can we distinguish in its effect this extreme of littleness from the vast itself. For division must be infinite as well as addition; because the idea of a perfect unity can no more be arrived at, than that of a complete whole, to which nothing may be added.

SECTION VIII.

INFINITY.

ANOTHER Source of the sublime is infinity; if it does not rather belong to the last. Infinity has a tendency to fill the mind with that sort of delightful horror, which is the most genuine effect, and truest test of the sublime. There are scarce any things which can become the objects of our senses, that are really and in their own nature infinite. But the eye not being able to perceive the bounds of many things, they seem to be infinite, and they produce the same effects as if they were really so. We are deceived in the like manner, if the parts of some large object are so continued to any indefinite number, that the imagination meets no check which may hinder its extending them at pleasure.

Whenever we repeat any idea frequently, the mind, by a sort of mechanism, repeats it long after the first cause has ceased to operate.* After whirling about,

* Part IV. sect. 11.

when we sit down, the objects about us still seem to whirl. After a long succession of noises, as the fall of waters, or the beating of forge-hammers, the hammers beat and the waters roar in the imagination long after the first sounds have ceased to affect it; and they die away at last by gradations which are scarcely perceptible. If you hold up a straight pole, with your eye to one end, it will seem extended to a length almost incredible.* Place a number of uniform and equi-distant marks on this pole, they will cause the same deception, and seem multiplied without end. The senses, strongly affected in some one manner, cannot quickly change their tenor, or adapt themselves to other things; but they continue in their old channel until the strength of the first mover decays. This is the reason of an appearance very frequent in madmen; that they remain whole days and nights, sometimes whole years, in the constant repetition of some remark, some complaint, or song; which having struck powerfully on their disordered imagination in the beginning of their frenzy, every repetition reinforces it with new strength, and the hurry of their spirits, unrestrained by the curb of reason, continues it to the end of their lives.

SECTION IX.

SUCCESSION AND UNIFORMITY.

SUCCESSION and uniformity of parts are what constitute the artificial infinite. 1. Succession; which is requisite that the parts may be continued so long and in such a direction, as by their frequent impulses on

*Part IV. sect. 13.

the sense to impress the imagination with an idea of their progress beyond their actual limits. 2. Uniformity; because, if the figures of the parts should be changed, the imagination at every change finds a check; you are presented at every alteration with the termination of one idea, and the beginning of another; by which means it becomes impossible to continue that uninterrupted progression, which alone can stamp on bounded objects the character of infinity. It is in this kind of artificial infinity, I believe, we ought to look for the cause why a rotund has such a noble effect.* For in a rotund, whether it be a building or a plantation, you can nowhere fix a boundary; turn which way you will, the same object still seems to continue, and the imagination has no rest. But the parts must be uniform, as well as circularly disposed, to give this figure its full force; because any difference, whether it be in the disposition, or in the figure, or even in the color of the parts, is highly prejudicial to the idea of infinity, which every change must check and interrupt, at every alteration commencing a new series. On the same principles of succession and uniformity, the grand appearance of the ancient heathen temples, which were generally oblong forms, with a range of uniform pillars on every side, will be easily accounted for. From the same cause also may be derived the grand effect of the aisles in many of our own old cathedrals. The form of a cross used in some churches seems to me not so eligible as the parallelogram of the ancients; at least, I imagine it is not so proper for the outside.

For,

* Mr. Addison, in the Spectators concerning the pleasures of the imagination, thinks it is because in the rotund at one glance you see half the building. This I do not imagine to be the real cause.

supposing the arms of the cross every way equal, if you stand in a direction parallel to any of the side walls, or colonnades, instead of a deception that makes the building more extended than it is, you are cut off from a considerable part (two thirds) of its actual length; and, to prevent all possibility of progression, the arms of the cross taking a new direction, make a right angle with the beam, and thereby wholly turn the imagination from the repetition of the former idea. Or suppose the spectator placed where he may take a direct view of such a building, what will be the consequence? the necessary consequence will be, that a good part of the basis of each angle formed by the intersection of the arms of the cross, must be inevitably lost; the whole must of course assume a broken, unconnected figure; the lights must be unequal, here strong, and there weak; without that noble gradation which the perspective always effects on parts disposed uninterruptedly in a right line. Some or all of these objections will lie against every figure of a cross, in whatever view you take it. I exemplified them in the Greek cross, in which these faults appear the most strongly ; but they appear in some degree in all sorts of crosses. Indeed, there is nothing more prejudicial to the grandeur of buildings than to abound in angles; a fault obvious in many; and owing to an inordinate thirst for variety, which, whenever it prevails, is sure to leave very little true taste.

SECTION X.

MAGNITUDE IN BUILDING.

To the sublime in building, greatness of dimension seems requisite; for on a few parts, and those small, the imagination cannot rise to any idea of infinity. No greatness in the manner can effectually compensate for the want of proper dimensions. There is no danger of drawing men into extravagant designs by this rule; it carries its own caution along with it. Because too great a length in buildings destroys the purpose of greatness, which it was intended to promote; the perspective will lessen it in height as it gains in length; and will bring it at last to a point; turning the whole figure into a sort of triangle, the poorest in its effect of almost any figure that can be presented to the eye. I have ever observed, that colonnades and avenues of trees of a moderate length were, without comparison, far grander than when they were suffered to run to immense distances. A true artist should put a generous deceit on the spectators, and effect the noblest designs by easy methods. Designs that are vast only by their dimensions are always the sign of a common and low imagination. No work of art can be great, but as it deceives; to be otherwise is the prerogative of nature only. A good eye will fix the medium betwixt an excessive length or height (for the same objection lies against both), and a short or broken quantity: and perhaps it might be ascertained to a tolerable degree of exactness, if it was my purpose to descend far into the particulars of any art.
