Heidegger brought up the problem of "Being" again, and used the specific object - "being" to explain the implication of "Being", esplically in "Being and being", "Being and God", "Being, time and history". We could get those implications from Heidegger's work - "Being and time". The essence of human beings exists in "being" and human being exists in the time of past, now and future.
