Section XX. The eye

I have hitherto purposely omitted to speak of the eye, which has so great a share in the beauty of the animal creation, as it did not fall so easily under the foregoing heads, though in fact it is reducible to the same principles. I think, then, that the beauty of the eye consists, first, in its clearness; what colored eye shall please most, depends a good deal on particular fancies; but none are pleased with an eye whose water (to use that term) is dull and muddy.17 We are pleased with the eye in this view, on the principle upon which we like diamonds, clear water, glass, and such like transparent¹ substances. Secondly², the motion of the eye contributes to its beauty, by continually shifting its direction; but a slow and languid motion is more beautiful than a brisk one; the latter is enlivening; the former lovely. Thirdly, with regard to the union of the eye with the neighboring parts, it is to hold the same rule that is given of other beautiful ones; it is not to make a strong deviation³ from the line of the neighboring parts; nor to verge⁴ into any exact geometrical figure. Besides all this, the eye affects, as it is expressive⁵ of some qualities of the mind, and its principal power generally arises from this; so that what we have just said of the physiognomy is applicable here.
