Kierkegaard’s parodied Hegel’s synthesis.
Kierkegaard did not want to abandon aesthetics altogether in favor of the ethical and the religious.
A key concept in the Hegelian dialectic, which Kierkegaard’s pseudonymous authorship parodies, is Aufhebung (sublation).
In Hegel’s dialectic, when contradictory positions are reconciled in a higher unity (synthesis) they are both annulled and preserved (aufgehoben).
Similarly with Kierkegaard’s pseudo-dialectic: the aesthetic and the ethical are both annulled and preserved in their synthesis in the religious stage.
