Soul

One of the main themes in Goethe's Faust is the soul. Faust trades his soul to have all of his wishes granted by Mephisto.

The soul is the ultimate prize for both the Lord and Mephisto. Early in the story, during Prelude in Heaven, the Lord and Mephisto make a bet regarding Faust's soul. The Lord believes that Faust can be saved until his dying breath but worries that Faust has corrupted his soul with his fascination and practice with the black arts. Mephisto says it will be easy to sway Faust and turn him away from the Lord. If Mephisto is right, he will take possession of Faust's soul and take it to Hell, where Faust will serve as an eternal slave.

In the story it is possible to interchange "soul" with "spirit". The soul is the part of a person that continues to exist after death...
