The present is never before us, whether it be a song, a year, a month, a day

Two-dimensional space depicted in three-dimensional spacetime. The past and future light cones are absolute, the "present" is a relative concept different for observers in relative motion

The present is never before us, whether it be a song, a year, a month, a day, the duration of a song, or a note in a song, the elusiveness of now is the elusiveness of time, the vanishing of the now concept loses its foundations.

This simple observation that – presence is never present – is a recurring tenet in the work of Heidegger. In Being and Time, there is a rejection of presence, as an undivided foundation of time
