Jealousy is both reasonable and belongs to reasonable men, while envy is base and belongs to the base, for the one makes himself get good things by jealousy, while the other does not allow his neighbor to have them through envy.

Pay attention to what you envy. Jealousy is an ugly emotion, but it tells the truth. You mostly envy those who have what you desire.

Jealousy is always a mask for fear: fear that we aren’t able to get what we want; frustration that somebody else seems to be getting what is rightfully ours even if we are too frightened to reach for it. At its root, jealousy is a stingy emotion.

Jealousy is that pain which a man feels from the apprehension that he is not equally beloved by the person whom he entirely loves.

Jealousy is perhaps the most involuntary of all strong emotions. It steals consciousness, it lies deeper than thought. It is always there, like a blackness in the eye, it discolours the world.

Envy is an indicator that alerts you if you’re being honest with yourself. If you can look at someone who has things you don’t and say, “You know what. I really don’t want that,” you know you’re in a good place. If you say you don’t want something but don’t mean it, envy will eat away at you. What it’s telling you is that you really do want it but are afraid to work for it.

With the wise man, what he has does not cease to be enjoyable because some one else has something else. Envy, in fact, is one form of vice, partly moral, partly intellectual, which consists in seeing things never in themselves but only in their relations

Jealousy, you know, is usually not an affair of causes. It is much more-how shall I say?-fundamental than that. Based on the knowledge that one's love is not returned. And so one goes on waiting, watching, expecting...that the loved one will turn to someone else.

Envy consists in seeing things never in themselves, but only in their relations. If you desire glory, you may envy Napoleon, but Napoleon envied Caesar, Caesar envied Alexander, and Alexander, I daresay, envied Hercules, who never existed.

jealousy knows more than truth does.

Now envy and antipathy, passions irreconcilable in reason, nevertheless in fact may spring conjoined like Chang and Eng in one birth. Is Envy then such a monster? Well, though many an arraigned mortal has in hopes of mitigated penalty pleaded guilty to horrible actions, did anybody ever seriously confess to envy? Something there is in it universally felt to be more shameful than even felonious crime. And not only does everybody disown it, but the better sort are inclined to incredulity when it is in earnest imputed to an intelligent man. But since it's lodgement is in the heart and not the brain, no degree of intellect supplies a guarantee against it.

Jealousy has the amazing power to illuminate a single person in an intense beam of light, keeping the multitude of others in total darkness.

Jealousy isn't a pleasant quality, but if it isn't overdone (and if it's combined with modesty), apart from its inconvenience there's even something touching about it.

Jealousy we understood and thought natural... But envy was a strange, new feeling for us. And all the time we knew that Maureen Peal was not the Enemy and not worthy of such intense hatred. The Thing to fear was the Thing that made her beautiful, and not us.
