In Franz Kafka's "Investigations of a Dog," the quote, "Today one may pluck out one's very heart and not find it," reflects a sense of existential angst and disconnection. This statement suggests that despite searching deeply within oneself, one may not discover true essence or identity. Such a feeling resonates with the modern struggle of finding meaning in a seemingly indifferent world.

The quote encapsulates the despair of the individual in contemporary society, where inner truth often feels elusive. Kafka's exploration of the nature of existence and the search for identity resonates with readers facing the complexities of their inner lives, highlighting the profound disconnection we may feel from our own hearts and selves.
