It requires courage even to leave the protective security of our four walls and enter the public realm, not because of particular dangers which may lie in wait for us, but because we have arrived in a realm where the concern for life has lost its validity. Courage liberates men from their worry about life for the freedom of the world. Courage is indispensable because in politics not life but the world is at stake.
-Hannah Arendt, Between Past and Future
