HENRY BOLINGBROKE: O, who can hold a fire in his hand By thinking on the frosty Caucasus? Or cloy the hungry edge of appetite By bare imagination of a feast? Or wallow naked in December snow By thinking on fantastic summer's heat? O, no! the apprehension of the good Gives but the greater feeling to the worse: Fell sorrow's tooth doth never rankle more Than when he bites, but lanceth not the sore.
