T 2.2.8.12

This reasoning will account for the origin of envy as well as of malice. The only difference betwixt these passions lies in this, that envy is excited by some present enjoyment of another, which by comparison diminishes our idea of our own: Whereas malice is the unprovok'd desire of producing evil to another, in order to reap a pleasure from the comparison. The enjoyment, which is the object of envy, is commonly superior to our own. A superiority naturally seems to overshade us, and presents a disagreeable comparison. But even in the case of an inferiority, we still desire a greater distance, in order to augment still more the idea of ourself. When this distance diminishes, the comparison is less to our advantage; and consequently gives us less pleasure, and is even disagreeable. Hence arises that species of envy, which men feel, when they perceive their inferiors approaching or overtaking them in the pursuit of glory or happiness. In this envy we may see the effects of comparison twice repeated. A man, who compares himself to his inferior, receives a pleasure from the comparison: And when the inferiority decreases by the elevation of the inferior, what shou'd only have been a decrease of pleasure, becomes a real pain, by a new comparison with its preceding condition.
