In this storm scene Lear is teetering on the brink of madness. So recently an arrogant and self-centered king doing precisely what Christ forbids in the Gospel, namely lording it over those under him, Lear is now reduced the famous "nothing" which is such a leitmotif throughout the play. Now noticing the suffering of common humanity and his indistinguishability from them, Lear cries out:
Poor naked wretches, whereso'er you are,This is Shakespeare expressing a quintessentially Christian understanding of the world turned upside down and the aristocracy of the poor in spirit. For the time being at least, it makes a nice prayer before meals.
That bide the pelting of this pitiless storm,
How shall your houseless heads and unfed sides,
Your loop'd and window'd raggedness, defend you
From seasons such as these? O, I have ta'en
Too little care of this! Take physic, pomp;
Expose thyself to feel what wretches feel,
That thou mayest shake the superflux to them,
And show the heavens more just.
As Robert Frost said: what worked for me may work for you.
