Where no good-will or friendship appears, it is difficult to conceive on what we can found our hope of advantage from the riches of others

Context

“we shall find none satisfactory, but that which derives it from the enjoyment communicated to the spectator by the images of prosperity, happiness, ease, plenty, authority, and the gratification of every appetite. Self-love, for instance, which some affect so much to consider as the source of every sentiment, is plainly insufficient for this purpose. Where no good-will or friendship appears, it is difficult to conceive on what we can found our hope of advantage from the riches of others; though we naturally respect the rich, even before they discover any such favourable disposition towards us. We are affected with the same sentiments, when we lie so much out of the sphere of their activity, that they cannot even be supposed to possess the power of serving us.” source
