There is a cultural current that carries humanity in and through history, which is one-directional and cannot be reversed.1 In a real sense there is a movement and progress, which is marked by a death that facilitates life. We never move on without leaving something behind. There is a letting-go and a welcoming of the new. In this sense there is no going back, or return, or revisiting at the deeper level of cultural flow. We can attempt to arrest this for ourselves, but this is to isolate oneself, or to live an illusion, and it is to some degree to abandon the common life of humanity in the present.
