"Don Quixote's misfortune is not his imagination, but Sancho Panza"

In this quote, Kafka is suggesting that Don Quixote's failure is not his wild creativity, however rather his faithful buddy, Sancho Panza. Don Quixote is known for his deceptions of grandeur and his belief that he is a knight on a mission for chivalry and honor. However, Sancho Panza, his squire, often brings him back to reality and tries to deter him from his foolish adventures. Kafka is implying that it is Sancho Panza's functionality and grounding affect that eventually results in Don Quixote's downfall. This quote highlights the power of impact and the repercussions of blindly following somebody else's concepts.
