  The two central features of action are freedom and plurality. By freedom Arendt does not mean the ability to choose among a set of possible alternatives (the freedom of choice so dear to the liberal tradition) or the faculty of liberum arbitrium which, according to Christian doctrine, was given to us by God. Rather, by freedom Arendt means the capacity to begin, to start something new, to do the unexpected, with which all human beings are endowed by virtue of being born. Action as the realization of freedom is therefore rooted in natality, in the fact that each birth represents a new beginning and the introduction of novelty in the world.
