“Merciful Heaven!”

Merciful Heaven!
Thou rather, with thy sharp and sulphurous bolt
Split’st the unwedgeable and gnarlèd oak,
Than the soft myrtle;—O, but man, proud man!
Drest in a little brief authority,
Most ignorant of what he’s most assured,
His glassy essence,—like an angry ape,
Plays such fantastic tricks before high heaven,
As make the angels weep.

William Shakespeare, from Measure for Measure
