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 pursuits of glory or happiness.
