Fortune and Vice had once a violent contest which of them had it most in their power to make mankind unhappy. Fortune boasted that she could take from men every external good, and bring upon them every external evil. “Be it so,” replied Vice, “but this is by no means sufficient to make them miserable without my assistance, whereas without yours I am able to render them completely so; nay, in spite, too, of all your endeavours to make them happy.”
