What is the role of Judge William in Either/Or?

In Søren Kierkegaard’s Either/Or, Judge William serves as the representative of the ethical stage of existence.1

His role is to challenge the aesthetic perspective, which he argues fails to form a cohesive self, leaving the individual as merely a fragmented "bundle of events". Rather than simply scolding the aesthete for immorality, Judge William attempts to demonstrate that choosing the ethical life allows an individual to become a true self with temporal continuity.1

He posits that the ethical does not abolish the aesthetic but rather ennobles it. He specifically presents marriage as the primary scene for this transformation, where commitment allows the sensuous to be raised to the level of spirit. Through this argument, Judge William acts as a bridge, illustrating how one might move from a life defined by fleeting interests to one defined by commitment and identity.1
