"El criticón (tomo 2 de 2)" by Baltasar Gracián y Morales is a philosophical novel published in three parts between 1651 and 1657. This allegorical masterwork follows two contrasting protagonists—impulsive Andrenio and prudent Critilo—on an epic journey through Spain, France, and Rome in search of Felisinda, representing happiness itself. Through satirical encounters and philosophical reflections, Gracián presents a bitter yet hopeful vision of human existence, exploring the eternal struggle between illusion and disillusionment across the stages of life.
