Walking on these streets, until the night falls, my life feels to me like the life they have. By day they’re full of meaningless activity; by night, they’re full of meaningless lack of it. By day I am nothing, and by night I am I. There is no difference between me and these streets, save they being streets and I a soul, which perhaps is irrelevant when we consider the essence of things.
Fernando Pessoa, from "A Factless Autobiography" in The Book of Disquiet, 1935 / 1982
