Man must be an emptiness, a nothingness, which is not a pure nothingness (reines Nichts), but something that is to the extent that it annihilates Being, in order to realize itself at the expense of Being and to nihilate in being. Man is negating Action, which transforms given Being and, by transforming it, transforms itself. Man is what he is only to the extent that he becomes what he is; his true Being (Sein) is Becoming (Werden), Time, History; and he becomes, he is History only in and by Action that negates the given, the Action of Fighting and of Work — of the Work that finally produces the table on which Hegel writes his Phenomenology, and of the Fight that is finally that Battle at Jena whose sounds he hearts while writing the Phenomenology. And that is why, in answering the “What am I?” Hegel had to take account of both that table and those sounds.
