With her life and phenomenological thought of political action, Arendt pointed us towards the reason of being of our political action: the so called 'Realm of Action'. Inscribed as it is into historical processes, action is conceived as the pure capacity to begin, animating and inspiring all human activities and constituting itself as a hidden source of every great and beautiful thing. The gap opened by totalitarianism and its annihilating force against political plurality, would be closed by thought and action combined into the realm of truly human ends.
