Swerve and Dyad

In Lucretius' basic image of Swerve, the deviation is with respect to antecedent motion in a straight line.  In other words, Swerve is a Binary concept, in which some antecedent condition is an essential term, though it does not determine what ensues, e. g. Free Will is a spontaneous modification of a given condition, like Acceleration with respect to constant Velocity. Some other prominent concepts that exemplify the pattern are experimentation, supererogatory action, musical theme-and-variation, and Evolutionary Variation and Mutation.  However, due to continued neglect of, and, perhaps, aversion to, Swerve, such potential fruitfulness has gone unrecognized.  On the other hand, in perhaps the closest thing to a notable Modern treatment of it, Marx's Dissertation, Swerve is misrepresented, because he attempts to reduce it to a Dialectical pattern, thereby implying, a reduction, via Sublation, of a Dyad to a Unitary term.  So, the general neglect of the concept may be due to its resistance to both incorporation into a system, and a simplification of it, i. e. to both Totalization and Atomization, the two main Philosophical operations.
