Candide’s love for Cunégonde is the driving force of his journey in the novel. The absurd lengths to which Candide goes to pursue his love, including abandoning the paradise of El Dorado, committing multiple murders, and barely avoiding capture and execution, are mocked by the reality that once Candide can marry Cunégonde, he’s no longer attracted to her. No real romantic love seems to exist in Candide.
Candide’s fixation on his own mental ideal of Cunégonde is a parallel to his desire to ignore reality while focusing on an idealized version of the world.
