"If in one way or another a person is afraid of being unable to maintain an overview of something that is multifarious and prolix, he tries to make or acquire a brief summary of the whole for the sake of a full view. For example, death is the briefest summary of life, or life traced back to its briefest form. This is also why it has always been very important to those who truly think about human life to test again and again, with the help of the briefest summary, what they have understood about life."
