A SKETCH of the MENTAL SYSTEM respecting our Perceptions of Taste, &c.

The mind of man, introspecting itself, seems, as it were, (in conjunction with the inscrutable principles of nature,) placed in the central point of the creation: from whence, impelled by her energetic powers and illumined by her light, the intellectual faculties, like rays, shoot forth in direct tendency to their ultimate point of perfection; and, as they advance, each individual mind imperceptibly imbibes the influence and light of each, and is by this imbibition alone enabled to approach it.

But, though the light of nature and of reason direct the human mind to perfection, or true good, yet, being in its progress perpetually impeded by adventitious causes, casual occurrences, &c. &c. which induce false opinions of good and evil, its progressive powers generally stop at a middle point between mere uncultivated nature and perfection, a medium which constitutes what we call common sense, and which, in degree, seems as distant from the perfection of the mental faculties as common form is from the perfection of form, beauty.

On meditating on this subject, and marking the progressive stages or degrees of human excellence, the great leading general truths, or mental rests, as I may call them, the common, the beautiful, the graceful, and the sublime, I have been naturally led to form a kind of diagrammatic representation of their respective distances, &c. &c. which I present to my reader on the opposite page, requesting him to refer to it now and then as he goes on, in order to facilitate his comprehension of my meaning.

And here it may be necessary to premise, that, however whimsical and absurd this delineation may appear to my reader, something analogous to the thought may be found in the works of many eminent philosophers, particularly in those of Bacon[A] and of Locke:[B] the latter suggesting that the whole system of morality might be reduced to mathematical demonstration; and the former, in his treatise on the Advancement of Learning, gives a description of the stages of science very much resembling my delineation of the stages of intellectual perfection, or taste.

Chap. 12th, same Book, Sect. 8th.]

It could have been no dishonour to me to have been led by such conductors! Yet, as the truth cannot dishonour me neither, I must aver, that my little system was projected, and brought to the exact state it now is in, without my having the least apprehension that any thing similar had been suggested before by any person whatever; nor have I, in consequence of the discovery I have lately made of the opinions of these respectable authors, added or omitted a single thought in my treatise. But to return from my digression.

In the exact center of my circle of humanity, I have placed nature, or the springs of the intellectual powers, which tend, in a straight line, to its boundary; and, on its boundary, I have placed demonstrable beauty and truth, and the utmost power of rules; and, midway; I have placed common sense and common form, half deriving their existence from pure nature, and half from its highest cultivation, as far as art or rules can teach. A conjunction which would itself be the perfection of humanity, but that it is mixed with all that is not nature, and all that is not art, and thereby made mediocrity, i.e. common sense.
