When we see any structure highly perfected for any particular habit, as the wings of a bird for flight, we should bear in mind that animals displaying early transitional grades of the structure will seldom continue to exist to the present day, for they will have been supplanted by the very process of perfection through natural selection.
Yet reason tells me, that if numerous gradations from a perfect and complex eye to one very imperfect and simple, each grade being useful to its possessor, can be shown to exist; if further, the eye does vary ever so slightly, and the variations be inherited, which is certainly the case; and if any variation or modification in the organ be ever useful to an animal under changing conditions of life, then the difficulty of believing that a perfect and complex eye could be formed by natural selection, though insuperable by our imagination, can hardly be considered real.
In looking for the gradations by which an organ in any species has been perfected, we ought to look exclusively to its lineal ancestors; but this is scarcely ever possible, and we are forced in each case to look to species of the same group, that is to the collateral descendants from the same original parent-form, in order to see what gradations are possible, and for the chance of some gradations having been transmitted from the earlier stages of descent, in an unaltered or little altered condition.
Though she had some indistinct idea of the method of these optical phenomena, still the illusion was almost perfect enough to warrant the belief that her husband possessed sway over the spiritual world.
She felt how much more precious was such a sentiment than that meaner kind which would have borne with the imperfection for her sake, and have been guilty of treason to holy love by degrading its perfect idea to the level of the actual; and with her whole spirit she prayed that, for a single moment, she might satisfy his highest and deepest conception.
"The concoction of the draught has been perfect," said he, in answer to Georgiana's look.
A charming old Italian writer has laid down the canons of perfect feminine beauty with much nicety in a delicious discourse, which, as he delivered it in a sixteenth- century Florentine garden to an audience of beautiful and noble ladies, an audience not too large to be intimate and not too small to be embarrassing, it was his delightful good fortune and privilege to illustrate by pretty and sly references to the characteristic beauties of the several ladies seated like a ring of roses around him.
Who could have prophesied in what way any of these inspired law-breakers would break the law, what new type of perfect imperfection they would create?
So we return to the Perfect Woman, having gained this much knowledge of her,--that her perfection is nothing more or less than her unique, individual, charming imperfection, and that she is simply the woman we love and who is fool enough to love us.
And it must be noted that I say of our reason, and not of our imagination or of our senses: thus, for example, although we very clearly see the sun, we ought not therefore to determine that it is only of the size which our sense of sight presents; and we may very distinctly imagine the head of a lion joined to the body of a goat, without being therefore shut up to the conclusion that a chimaera exists; for it is not a dictate of reason that what we thus see or imagine is in reality existent; but it plainly tells us that all our ideas or notions contain in them some truth; for otherwise it could not be that God, who is wholly perfect
and veracious, should have placed them in us.
