Faust: What is thy name?
Mephistopheles: A part of The Power which always wills The Bad and always works The Good.
Meaning: Mephistopheles is The Spirit Of Negation and exists through Opposition to The Positive Truth And Order And Beauty which proceed from the never-ending creative energy of The Deity. In The Prologue to Faust, The Lord declares that Man’s active nature would grow sluggish in working The Good and therefore he has to be aroused by The Spirit of Opposition. The Spirit wills The Bad but of itself it can do nothing positive and by its Opposition always works The Opposite of what it wills.
