In short, that which up to now we have called 'presence' was regarded by Heidegger as 'absence', and that which up to now was called 'absence' he considered to be 'presence'. Heidegger's thought was to some extent directed against the 'the world-enslavement' of an acosmically composed subjectivity. It is in this sense that we read in the paper Beiträge zur Philosophie (vom Ereignis) (Contributions to Philosophy (From the Event)) - published for the first time on his 100th birthday: If, namely, being-present is experienced as the creative foundation of human existence and it thereby becomes known that being-present is only moment and history, usual human existence must be determined from this as being-absent. It is absent out of the composition of being and complete only in the being as the existing (oblivion of being). The human being is the absent. Being absent is the more original title for the unreality of being-present.
