National prejudices and hatreds seldom extend beyond neighbouring nations.

Context

“That wisdom which contrived the system of human affections, as well as that of every other part of nature, seems to have judged that the interest of the great society of mankind would be best promoted by directing the principal attention of each individual to that particular portion of it, which was most within the sphere both of his abilities and of his understanding. National prejudices and hatreds seldom extend beyond neighbouring nations. We very weakly and foolishly, perhaps, call the French our natural enemies; and they perhaps, as weakly and foolishly, consider us in the same manner. Neither they nor we bear any sort of envy to the prosperity of China or Japan.” source
