"Dear Rudel -
what I need most bitterly is a new machine which should be capable of transposing thoughts into written words, put these into envelopes and mail them to the right address. As long as this machine has not been invented, I probably shall not be able to keep out of letter-trouble and consequently out of trouble with my friends. I actually have written you many letters – only I am well aware that you never did get any of them. Only reason: Lack of the proper machinery."
Hannah Arendt in einem Brief an Salomon Adler-Rudel, 02.11.1943
