Faust (n.) is a historical idea, so every notable era will have its own Faust; Don Juan will always stand alone.
Faust (n.) is the daemonic determined as the intellectual, as Don Juan is the daemonic determined as the sensuous — the two Titans of the Middle Ages.
Faust (n.) seduces only one girl where Don Juan seduces hundreds — but she is seduced and crushed far more deeply, because Faust's seduction is intellectual.
Faust (n.) seeks in the sensuous not enjoyment but diversion from the nothingness of doubt; girls do not dance into his embrace — he frightens them to him.
Faust (n.) would find a cultured woman nothing — she belongs in his own relativity; only an innocent girl, nothing beside him, is also tremendously much, because she is immediacy.
