In equal degrees of merit there is scarce any man who does not respect more the rich and the great, than the poor and the humble.

Context

“In some particular features they are, no doubt, different, but, in the general air of the countenance, they seem to be so very nearly the same, that inattentive observers are very apt to mistake the one for the other. In equal degrees of merit there is scarce any man who does not respect more the rich and the great, than the poor and the humble. With most men the presumption and vanity of the former are much more admired, than the real and solid merit of the latter. It is scarce agreeable to good morals, or even to good language, perhaps, to say, that mere wealth and greatness, abstracted from merit and virtue, deserve our respect.” source
