Faustus

How comes it then that thou art out of hell?

Maphastophilis

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 then thousand hells
In being deprived of everlasting bliss!
O Faustus, leave these frivolous demands,
Which strike a terror to my fainting soul.

The Renaissance Idea of "Hell Within"

Building on the idea of exile and its associated alienation, allegorical and psychological interpretations (of hell) multiplied. Though he describes many gruesome physical torments in the Inferno, Dante identifies hell's essence while describing souls encased in flames: "Each one swathes himself in that which makes him burn" (26.48). The reformer Martin Luther put the afterlife in a psychological context, too, when he declared in 1517, "Hell, Purgatory, and Heaven appear to differ as despair, almost despair, and peace of mind differ." Of his own spiritual rebirth he said, "I felt that I was altogether born again and had entered paradise itself through open gates."

If faith is the way to heaven, hell begins even before death, when the faithless soul endures isolation and disorientation. As Luther put it, "Everyone carries his own hell with him wherever he is." Though earlier theology anticipates the statement, Calvin appears the first (1534) to say "Hell is not a place but a condition."
