“Symmetry of form, though implied in geometrical regularity, is not identical with it, and requires a separate consideration. The beauty of forms geometrically symmetrical, in contradistinction from those deficient in the correspondence of opposite halves, depends upon two similar series of actions in different pairs or muscles. For example, the survey of an ovate leaf, or indeed that of almost any vegetable leaf—so numerous are the provisions for our gratification—requires for its opposite halves two series of muscular actions, the different parts of the one corresponding with those of the other in duration, intensity, and order of succession. The gratification in this case results from the harmony of muscular sensations individually pleasurable. The agreeableness of this harmony may depend upon a principle more psychological than that of the agreeableness of its elementary sensations. Yet the former is to a certain extent susceptible of a physiological generalization. This harmony would probably have been impaired by any considerable inequality in the distances between the points of insertion of the recti muscles, or in the strength of the antagonists. It is a curious coincidence, that in both these respects, these muscles are more nearly symmetrical than any others in the human body. Physiology, then, explains, not only the agreeableness of the elementary sensations, which give rise to the perception of beauty in regular curves, but unfolds the provisions for two similar series of such sensations, not only in figures simply regular, but in those which are simply symmetrical, and in those which are both symmetrical and regular. The principles of muscular action explain the agreeableness of a rapid succession of varied actions equally distributed among the muscles, and the structure of the optical apparatus explains why the curvature and regularity of an object require such actions in vision. Again, we discover in the symmetrical structure and arrangement of the ocular muscles, a provision for two similar series of pleasurable sensations in the survey of a symmetrical figure, in whatever position it may be placed, provided it retains its symmetry with respect to some visual plane. The coincidence between the location of the ocular muscles diametrically opposite, on the one hand, and our propensity to compare the opposite halves of bodies, and the pleasure afforded by their similarity on the other hand, is curious, and to a certain extent affords a physiological explanation of the beauty of symmetrical forms.
“The same principles which apply to the beauty of form of inanimate objects are applicable to the paths described by them in motion. The intrinsic beauty of their motions is exclusively referrible to sensations in the ocular muscles of the observer, while the gracefulness of human motions is referrible in part to these, and in part to sensations in other muscles.
“It would be foreign to the subject of the present memoir, to consider the beauty of expression of the human countenance; although this species of beauty is in a great degree referrible to muscular action. That muscular action which belongs to the present topic is not that of the object, but that of the observer. It may be scarcely necessary again to disclaim any design of giving a complete analysis of beauty in general, or to repeat the concession that man’s notions of beauty are modified by various associations.
“Final Cause.—The benevolence of the Author of nature is strikingly manifested in connecting present pleasure with obedience to the natural laws. It has been shown that vision is attended with muscular action which is generally pleasurable. If seeing had required no muscular action, we should have wanted one of our present stimuli to the acquisition of knowledge. This stimulus is especially necessary in infancy, and then powerfully prompts to observation, even anterior to the dawnings of intellectual curiosity, with which it subsequently co-operates. We see, in this arrangement, the exemplification of a principle which extensively pervades the laws under which we are placed by the Creator—which is, that mental attainments, as well as other acquisitions, shall require action; and that action shall be attended with pleasure. Whether the acquisition is to be made by the manual labor of the artisan, by the manipulations of the artist, the chymist, or the experimental philosopher, by the sedentary student of books, or by the observer of natural phenomena in his original survey of the universe—in every case it is muscular action.
“This application to natural theology, has thus far had reference to that degree of intrinsic agreeableness which is common to forms in general. But the laws of nature specially tend to the production of curved, regular, and symmetrical objects and motions, in inorganic vegetable and animal bodies; and impose the necessity of similar forms in artificial structures. With a different structure and arrangement of the ocular muscles, those forms peculiarly conducive to our welfare and that of the universe, had possessed no peculiar attractions; and we had felt no special impulse of this kind to conform our own artificial structures to those laws of nature, or to investigate many of the most important works of the Creator. Yet neither gravity or any other law of the external world could have determined the peculiar formation of the muscles of the human eye. We must, therefore, refer their actual structure and location to that Being who gives to the objects of his creative power, and to the principles by which he governs them, such a mutual adaptation as conduces to the greatest achievable good. Thus, while muscular pleasure originally prompts to the observation of the Creator’s works, this observation is rewarded and subsequently prompted by a pleasure of an incomparably higher order, of a character purely mental, by the discovery of moral beauty, which in rank and refinement surpasses all others. Still, the muscular pleasure of the eye strongly incites to the examination of the numberless forms of beauty in the organic and inorganic kingdoms, such as the symmetrical leaf, the bending bough, the symmetry of the tree itself that of inferior animals, and of the human form. Or we may extend our view to the circular or undulating horizon, the apparent limits of the apparently round world; or we may elevate the eyes to the arched dome of the firmament, on which the arches of the iris and aurora occasionally confer additional beauty. Or with the telescope we may pierce this apparent limit of upward vision, and discover beyond it a universe of spherical and spheroidal worlds, revolving in circular and elliptical orbits, worlds and orbits which present, even in our diminutive diagrams, a high order of beauty, designed to incite us to the contemplation of these most magnificent works of the Creator.
“All this beauty had been lost to man, but for the property of the eye, which, on a superficial reflection, might seem a defect. It is no less true than paradoxical, that the perception of these beauties depends on indistinctness of vision. To a being so constituted as to see with equal distinctness by oblique and direct vision, the same forms might be presented, but not as forms of beauty. Has the Creator, then, sacrificed a portion of our perceptive powers to our sensual gratification? I answer no. Has he, then, sacrificed a portion of our direct means of acquiring knowledge, to afford an incitement which should ultimately and indirectly enhance our attainments? Again I am compelled to answer in the negative. There is, in this arrangement, no intellectual sacrifice whatever, direct or indirect. This indistinctness of oblique vision, which might seem a defect, I consider an excellence. A simultaneous and distinct impression received from the whole field of vision, would distract the attention and preclude a minute and accurate examination of any particular part. But as our eyes are so constituted as to receive a strong and distinct impression only from the images of those objects toward which their axes are directed, and as our minds are so constituted that we can in a great measure neglect the weaker or less distinct impressions, we are able to acquire a more exact knowledge of any part of the field to which we choose to attend. To see every thing at once, would be to examine nothing. Such a constitution of the eye would be to vision what an indiscriminating memory is to the understanding.

STANDARD OF BEAUTY.
To show that the sentiments of mankind with regard to female beauty, have been very various in different ages and nations, and that it is not possible to establish a standard which shall comprehend all, without discriminations, a few facts may be mentioned. Among the ancients, a small forehead and joined eyebrows were much admired in a female countenance; and in Persia, large joined eyebrows are still highly esteemed. In some parts of Asia, black teeth and white hair, are essential ingredients in the character of a beauty; and in the Marian Islands, it is customary among the ladies to blacken their teeth with herbs, and to black their hair with certain liquors. Beauty, in China and Japan, is composed of a large countenance, small, and half-concealed eyes, a broad nose, little and useless feet, and a prominent belly. The Flat-head Indians compress the heads of their children between two boards, with a view to enlarge and beautify the face; some tribes compress the head laterally; others depress the crown, and others make the head as round as possible. “The Moors of Africa,” says Park, “have singular ideas of female perfection; the gracefulness of figure and motion, and a countenance enlivened by expression, are by no means operative points in their standard; with them corpulency and beauty are terms nearly synonymous. Or women of even moderate pretensions, must be one who cannot walk without a slave under each arm to support her, and a perfect beauty is a load for a camel. In consequence of this prevalent taste for unwieldiness of bulk, the Moorish ladies take great pains to acquire it early in life, and for this purpose many of the young girls are compelled by their mothers to swallow a great quantity of kouskous, and drink a large bowl of camel’s milk every morning. It is of no importance whether the girl has an appetite or not, the kouskous and milk must be swallowed, and obedience is frequently enforced by blows. I have seen a poor girl sit crying with the bowl at her lips for more than an hour, and her mother with a stick in her hand watching her all the while, and using the stick without mercy whenever she observed that her daughter was not swallowing. This singular practice, instead of producing indigestion and disease, soon covers the young lady with that degree of plumpness, which in the eye of a Moor, is perfection itself.” These facts show that every nation almost has ideas of beauty peculiar to itself; and it is no less evident that nearly every individual has his own notions and taste concerning it. “The empire of beauty, however,” says a writer already quoted, “amid these discordant ideas, with respect to the qualities in which it consists, has been very generally acknowledged, and particularly in all civilized countries; and when it is united with other accomplishments that tend to render females amiable, it contributes in no small degree, to give them importance and influence, to polish the manners of society, and to contribute to its order and happiness.”
