Tempo e história: algumas aproximações acerca do presente em Walter Benjamin e Martin Buber

The concepts of "present" by Martin Buber and Walter Benjamin seem to be equivalent. Buber´s is refered as "Gegenwart", a word that means both "present" (in a temporal sense) and "presence". Benjamin´s is refered as "Jetztzeit". Both them implicate a qualitative time, not a linear, chronological one, and regard the present as breakthrough - as much in the chain of causality as in the determinism of natural and historicist laws - and crossroad of temporalities, where past and future join together.
