Jealousy is in a manner just and reasonable, as it tends to preserve a good which belongs, or which we believe belongs to us, on the other hand envy is a fury which cannot endure the happiness of others.
Francois de La RochefoucauldNo matter how much care we put into hiding our passions under the appearances of devotion and honor, they can always be seen to peer out through these covers.
