What is earthly happiness? that phantom of which we hear so much, and see so little; whose promises are constantly given and constantly broken, but as constantly believed; that cheats us with the sound instead of the substance, and with the blossom instead of the fruit. Like Juno, she is a goddess in pursuit, but a cloud in possession.
