T 2.1.12.4

'Tis plain, that almost in every species of creatures, but especially of the nobler kind, there are many evident marks of pride and humility. The very port and gait of a swan, or turkey, or peacock show the high idea he has entertain'd of himself, and his contempt of all others. This is the more remarkable, that in the two last species of animals, the pride always attends the beauty, and is discover'd in the male only. The vanity and emulation of nightingales in singing have been commonly remark'd; as likewise that of horses in swiftness, of hounds in sagacity and smell, of the bull and cock in strength, and of every other animal in his particular excellency. Add to this, that every species of creatures, which approach so often to man, as to familiarize themselves with him, show an evident pride in his approbation, and are pleas'd with his praises and caresses, independent of every other consideration. Nor are they the caresses of every one without distinction, which give them this vanity, but those principally of the persons they know and love; in the same manner as that passion is excited in mankind. All these are evident proofs, that pride and humility are not merely human passions, but extend themselves over the whole animal creation.
