What? Because I have no idea what is the joke
In this excerpt from the play The Tragical History of Doctor Faustus, the line that provides evidence that Faustus's human soul is predisposed to shun evil is the second one:
But, Mephistophilis, My blood congeals,
and I can write no more.
This line, as Marlowe uses blood as a symbol for the character of Faustus's soul, shows the reader his intention to avoid evil, but he feels he can't because it "<em>congeals</em>".
