There are two critical, but opposite interpretations of Heidegger’s understanding of being as a social ontology. One charges Heidegger with adhering to an anti-social “private irony,” while the other charges him with promoting a “self-canceling” totality. The current essay replies to these two charges with a discussion of Heidegger’s understanding of being as “communal being,” which is implicated both in the early Heidegger’s concept of “being-in-the-world-with-others” and in the later Heidegger’s keyword of Ereignis. It argues that Heidegger’s understanding of being as communal being is neither identical with totalitizing publicness nor the same as voluntaristic egotism. According to Heidegger, both the publicness of das Man and voluntaristic egotism are the real threats to humanity at present. Because of them, we human beings are in danger of being uprooted from the earth upon which we—as communal beings—have already and always dwelled and lived with others from the very beginning of human history.
