In his correspondence with Felice, Franz Kafka reflects on the nature of human relationships and individuality. He emphasizes that people must be accepted for who they truly are, as attempts to change them are often futile and can disrupt their equilibrium. This perspective suggests that the complexity of a human being cannot be simplified to just one aspect that can be substituted or altered.

Kafka's insight highlights the importance of embracing the entirety of a person's character instead of wishing to modify particular traits. Relationships flourish when individuals acknowledge and accept each other wholly, thus maintaining the delicate balance that defines their interactions. Change is a nuanced process that cannot be forced; it must come from within the individual.
