Duration, Repetition, Rhythm

An alternative to both Duration and Repetition is Rhythm.  Rhythm shares continuity and vitality with the former, while entailing more clearly the heterogeneity that is ingredient in any Change.  On the other hand, it shares with the latter objectivity, i. e. it cannot be reduced to mere psychological datum, and it gives meaning to the part of a cycle that is not the moment that is enumerated, e. g. between the "1 second" and the " 2 seconds".  So, like Duration, Rhythm is irrelevant to the Repetition that is basis of the quantification of Physicist Mass in motion.  But, if Einstein means to reduce human Time to the latter, just as he reduces human behavior to Inanimate Determinism, then, as an objective characteristic, Rhythm more decisively than Duration exposes the dehumanization involved.
