Birth
The "birth" could be the main concept of a philosophy of the commencement: indeed it is not only a biological event or an effective metaphor for new beginning, but also the sign that being, knowledge and action, born themselves, have the power to give birth to something. Birth is essentially which has neither memory nor appropriation of itself: it's a destiny and a choice that confirm the features of necessity and freedom bound in every coming into the world. Thoughts about birth can be found per exempla in Arendt's, Nietzsche's and Vico's works as well as in the ancient and modern age, wherever the burden of the change has been felt. The concept of birth passes through the contemporary philosophy which wants to rebuild the historical framework of the critical reflection.
