Arendt, Nietzsche, and Power

In her personal library, Hannah Arendt had this copy of Walter Kaufmann's Nietzsche: Philosopher, Psychologist, Antichrist, a book which helped to restore Nietzsche's prominence in the study of philosophy following the events of the Second World War. As we can see in the photographs below, Arendt found two passages sufficiently interesting to note them in her reading. The first section is as follows:

Great power reveals itself in self-mastery. While a weak state may kill off all dissenters, a strong state should be able to tolerate them.

The second passage reads:

"Giving style" to one's character--a great and rare art! It is exercised by those who see all the strengths and weaknesses of their own nature and then comprehend them in an artistic plan until everything appears as art and reason.
