“The possibility of writing letters must have brought to the world a terrible disturbance of souls. Because it is a relationship with ghosts - and not only with the ghost of the recipient, but also with his own. Who is allowed to allow people to have correspondence relationships! ”Letter from Franz Kafka to Milena Jesenska, 1920.
