Doctor Faustus

Marlow's concept of Hell isn't so much a physical space as it is a mental state. When Faustus askes Mephostophilis why he is out of Hell, he answers,

Why, this is hell, nor am I out of it
Think’st thou that I, who saw the face of God
And tasted the eternal joys of heaven
Am not tormented with ten thousand hells
In being depriv’d of everlasting bliss?

Hell is not a place where bad people are condemned to, it is a state of mund. Marlow can this use it as a metaphor for people who choose to live out of God's favor.
