Aristotle gets a B minus, mainly for effort. It took Christianized society to understand (and promptly forget) that envy/jealousy are two sides of the same anti-God coin.
Keep in mind that Aristotle is talking about two Greek words that may be more distinct in his context than the English words "envy" and "jealousy".
There is indeed a difference between seeing somebody with something nice and deciding "I'm going to have one of those too" versus "If I can't have one, then he should also be deprived of it".
Yet Envy is the only one that made it to Deadly Sin status. Jealousy is a natural emotion. Envy is evil.
I just can’t see jealousy as near enough to envy to be on the same coin. They share neither motive nor result, unless result is measured in relative terms. Envy is what Zero’s Communist followers feel when they support his want to punish the producers. It is Communism... trickle up poverty. Jealousy is what I feel when I work an extra shift to afford that thing that Mr. Jones has sitting in his driveway. Jealousy never strays from the bounds of human freedom. It may not be the holiest of motivations, but it gets the job done as a way for us to see “examples” of what we would like to have. Yes, it’s certainly not holy, but neither is it a deadly sin.
How about... jealousy is a worn and shiny coin, while envy is an old beat up piece of paper money, which had been used for something unnatural? :)
