This argument I esteem just and decisive; but in order to give greater authority to the present reasoning, let us suppose it false for a moment, and see what will follow. It is certain, then, that if the power of producing pleasure and pain forms not the essence of beauty and deformity, the sensations are at least inseparable from the qualities, and it is even difficult to consider them apart. Now there is nothing common to natural and moral beauty, (both of which are the causes of pride) but this power of producing pleasure; and as a common effect supposes always a common cause, it is plain the pleasure must in both cases be the real and influencing cause of the passion. Again; there is nothing originally different betwixt the beauty of our bodies and the beauty of external and foreign objects, but that the one has a near relation to ourselves, which is wanting in the other. This original difference, therefore, must be the cause of all their other differences, and among the rest, of their different influence upon the passion of pride, which is excited by the beauty of our person, but is not affected in the least by that of foreign and external objects. Placing, then, these two conclusions together, we find they compose the preceding system betwixt them, viz, that pleasure, as a related or resembling impression, when placed on a related object by a natural transition, produces pride; and its contrary, humility. This system, then, seems already sufficiently confirmed by experience; that we have not yet exhausted all our arguments. It is not the beauty of the body alone that produces pride, but also its strength and force. Strength is a kind of power; and therefore the desire to excel in strength is to be considered as an inferior species of ambition. For this reason the present phænomenon will be sufficiently accounted for, in explaining that passion. Concerning all other bodily accomplishments we may observe in general, that whatever in ourselves is either useful, beautiful, or surprising, is an object of pride; and it's contrary, of humility. Now it is obvious, that every thing useful, beautiful or surprising, agrees in producing a separate pleasure and agrees in nothing else. The pleasure, therefore, with the relation to self must be the cause of the passion.
