The very idea of evolution necessitated a fundamental shift in thinking, casting previously ironclad ideas into doubt. So, too, does Chopin depict Edna's shift in perspective as causing an irreparable break with her former life, disallowing the possibility that she can simply move back into Léonce's house and resume her limiting life.
