Swerve and Physics

According to Lucretius, Swerve is fundamentally a description of the behavior of Atoms. Thus, it constitutes a Physics.  Now, three characteristics of Swerve are: it is not the effect of a prior cause, it is not the effect of an external cause, and the direction of motion to which it changes is indeterminate.  A fourth is that it is unquantifiable.  In other words, Lucretian Physics is antithetical to Newtonian Physics in four fundamental ways.  But, Newtonian Physics is among the predominant influences of Modernity, both intellectually and practically, i. e. its technological consequences.  So, perhaps the greatest weakness of Greenblatt's thesis is its application to Physics.  Regardless, Lucretian Physics may offer explanations for phenomena ignored or suppressed by its Newtonian counterpart.  But, until it also accounts for the regularities that the latter has so effectively represented for centuries, it might complement it, but not supplant it.
