Becoming—or change—and duration—or measurement—are the two aspects of time. This represents a new perspective, even though I have previously discussed the becoming-duration duality.
Becoming is the continuous and irreversible succession of changes or phenomena. Duration is the interval between two sequential moments, one of which marks the beginning and the other the end.
In the becoming-memory-duration trilogy, memory is included because it is the medium in which the intervals—or measurements—of time are processed. The becoming-duration duality is an established concept, dating back to September 17, 2012. Time consists of becoming (which is perceptible) plus duration (which is sub-perceptible). Becoming may be either simple or periodic. In clocks, we observe a periodic becoming. From this perspective, duration is an epiphenomenon of becoming, rather than being time itself. The conceptualization of time shifts to encompass the following aspects: objective, becoming (perceptible), duration (sub-perceptible), and measurable. Prior to addressing this topic, I had not regarded becoming as an aspect of time, but rather as its material basis.
