Envy is best defined as a resentful emotion that "occurs when a person lacks another's (perceived) superior quality, achievement or possession and wishes that the other lacked it."[1]
Bertrand Russell said envy was one of the most potent causes of unhappiness.[2] Not only is the envious person rendered unhappy by his envy, but they also wish to inflict misfortune on others. Although envy is generally seen as something negative, Russell also believed that envy was a driving force behind the movement towards democracy and must be endured to achieve a more just social system.[3] However, psychologists have recently suggested that there may be two types of envy: malicious envy and benign envy - benign envy being proposed as a type of positive motivational force.

Envy is known as one of the most powerful human emotions for its ability to control one as if envy was an entity in itself. Countless men and women have fallen prey to brief periods of intense envy followed by anger which then translates into aggression. One of the most common examples is a woman who is envious of another's beauty, such as in the fairy tale "Snow White," in which the evil stepmother is envious of Snow White's youth and beauty, and seeks to kill the young woman in order to once again be the "fairest of them all."
