The existence or non-existence of these advantages, and the power of determining this, or the judgment of beauty, are therefore of transcendent importance to individuals and to families. Such judgment can be attained by analysis and classification alone. Nothing, therefore, can more nearly affect all human interests than that analysis and classification of beauty which are here proposed.

To place beyond a doubt, and to illustrate more minutely, the extraordinary importance of this subject, as regards advantages real to the species, I may anticipate some of the more minute applications of my doctrine.

If, in the locomotive system of the female, much of the delicacy of form, and the ease and grace of her movements, depend upon the more perfect development of the muscles of the pelvis, and its easily adapting itself to great and remarkable changes, how important must be the ability to determine, even by walk or gesture, the existence of this condition!

If, in the vital system, the elasticity and freshness of the skin are the characteristics of health, and their absence warns us that the condition of woman is unfavorable to the plan of nature relatively to the maintenance of the species—or, if the capacity of the pelvis, and the consequent breadth of the haunches, are necessary to all those functions which are most essentially feminine, impregnation, gestation, and parturition, without danger either to parent or to child—of what extreme importance must be the ability to determine this with certainty and ease!

If, in the mental system, the capacity and delicacy of the organs of sense, and the softness and mobility of the nervous system, are necessary to the vivid and varying sensibility of woman—if it is in consequence of this, that woman is enabled to act on man by the continual observation of all that can captivate his imagination or secure his affection, and by the irresistible seduction of her manners—if it is these qualities which enable her to accommodate herself to his taste, to yield, without constraint, even to the caprice of the moment, and to seize the time when observations, made as it were accidentally, may produce the effect which she desires—if it is by these means that she fulfils her first duty, namely, to please him to whom she has united her days, and to attach him to her and to home by rendering both delightful—if all this is the case, of what inexpressible importance must be the ability to determine, in each individual, the possession of the power and the will to produce such effects!

If (descending to still more minute inquiries) external indications as to figure are required as to parts concealed by drapery—if such indications would obviate deception even with regard to those parts of the figure which are more exposed to observation by the closer adaptation of dress—if, even when the face is seen, the deception as to the degree of beauty, is such that a correct estimate of it is perhaps never formed—if indications as to mind may be derived from many external circumstances—if external indications as to the personal habits of women are both numerous and interesting—if such indications even of age and health are sometimes essential—if all this be the case, let the reader say what other object of human inquiry exceeds this in importance.

Let us not then deceive ourselves respecting the source of those impressions which one sex experiences from the sight of the other. It is evidently nothing else than the more or less delicate and just perception of a certain conformity of means with a want which has been created by nature, and which must be satisfied.

“It is very obvious,” says Dr. Pritchard, “that this peculiarity in the constitution of man must have considerable effects on the physical character of the race, and that it must act as a constant principle of improvement, supplying the place in our own kind of the beneficial control [in the crossing of races] which we exercise over the brute creation.” And he adds: “This is probably the final cause for which the instinctive perception of human beauty was implanted by Providence in our nature.”

We need not wonder, then, that the Greeks should have preferred beauty to all other advantages, should have placed it immediately after virtue in the order of their affections, or should have made it an object of worship.

Even the practical application of this principle to the improvement of the human race is not a matter of conjecture. We have seen both families and nations ameliorated by the means which it affords. Of this, the Turks are a striking example. Nothing, therefore, can better deserve the researches of the physiologist, or the exertions of the philanthropist, than the fact that there are laws, of which we have yet only a glimpse, according to which we may influence the amelioration of the human race in a manner the most extensive and profound, by acting according to a uniform and uninterrupted system.
