Portrait of a Woman Suffering from Obsessive Envy; ThÃ©odore GÃ©ricault. Envy (from Latin invidia) is an emotion which occurs when a person lacks another's superior quality, achievement, or possession and either desires it or wishes that the other lacked it. Bertrand Russell said that envy was one of the most potent causes of unhappiness.
We all feel envy from time to time, no matter how much we want to believe weâre above it. Envy is a complex cluster of feelings that stems from a very basic desire: You want what you believe someone else has. According to Buunk et al. (2012), envy is a response to another person who has success, skills, or qualities that we desire, and involves feeling a lack in comparison to that person.
