Envy is that passion which views with malignant dislike the superiority of those who are really entitled to all the superiority they possess. The man, however, who, in matters of consequence, tamely suffers other people, who are entitled to no such superiority, to rise above him or get before him, is justly condemned as mean-spirited.

Context

“The want of proper indignation is a most essential defect in the manly character, and, upon many occasions, renders a man incapable of protecting either himself or his friends from insult and injustice. Even that principle, in the excess and improper direction of which consists the odious and detestable passion of envy, may be defective. Envy is that passion which views with malignant dislike the superiority of those who are really entitled to all the superiority they possess. The man, however, who, in matters of consequence, tamely suffers other people, who are entitled to no such superiority, to rise above him or get before him, is justly condemned as mean-spirited. This weakness is commonly founded in indolence, sometimes in good-nature, in an aversion to opposition, to bustle and solicitation, and sometimes, too, in a sort of ill-judged magnanimity, which fancies that it can always continue to despise the advantage which it then despises, and, therefore, so easily gives up.” source
