at least, that these proportions would not differ much from perfect symmetry.
The desires excited by the beauty of the person increase for some time, especially if the sensible ones are not gratified, and there be also a mixture of hope and fear, in the relation to the attainment of the affections of the beloved person. But they sometimes decrease, like other desires, from mere want of novelty, after the affections are gained; and must always do so after gratification. Nevertheless, if there be the proper foundation for esteem and religious affection in each party, mutual love, with the pleasures arising from it, may increase upon the whole, the real circumstances of life affording more than sufficient opportunity for gaining in one respect what is lost in another.
The beauty of the air, gesture, motions, and dress, has a great connexion with the beauty of the person, or rather makes a considerable part of it, contributing much to the sum total; and when considered separately, receiving much from the other part of the beauties of the person. The separate beauty of these things arises from some imitation of a natural or artificial beauty already established, from fashion, high birth, riches, &c. or from their being expressive of some agreeable or amiable quality of mind. The reciprocal influences of our ideas upon each other, and the endless variety of their combinations, are eminently conspicuous in this article; the strength of desire here rendering the associations, with the several steps previous to the perfect coalescence of the ideas associated, more visible than most other cases.
I come now to examine the pleasures of mirth, wit, and humour.
But, first, it will be necessary to consider the causes of laughter, and particularly the mental ones.
Now it may be observed, that young children do not laugh aloud for some months. The first occasion of doing this seems to be a surprise, which brings on a momentary fear first, and then a momentary joy in consequence of the removal of that fear, agreeably to what may be observed of the pleasures that follow the removal of pain. This may appear probable, inasmuch as laughter is a nascent cry, stopped of a sudden; also because if the same surprise, which makes young children laugh, be a very little increased, they will cry. It is usual, by way of diverting young children, and exciting them to laughter, to repeat the surprise, as by clapping the hands frequently, reiterating a sudden motion, &c.
This is the original of laughter in children, in general; but the progress in each particular is much accelerated, and the occasions multiplied, by imitation. They learn to laugh, as they learn to talk and walk; and are most apt to laugh profusely,
