Free Will, Determinism, Swerve

A neglected alternative to the standard varieties of both Free Will and Determinism is Lucretian Swerve.  Swerve is not a characterless singularity; rather, its Logical structure is Variation, which entails, more precisely, Variation of some given.  Thus, it is relative to its antecents, but is neither their mechanical effect, nor their deductive consequence.  The pervasive neglect of the concept is for the same reason that Deleuze attributes to the pervasive neglect of Difference--the chronic privileging of Sameness.  It is a potentially fruitful concept, applicable to creativity, i. e. the generation of Novelty, and is specifically exemplified by the motor of Evolution--Mutation.  Plus, it can explain why Effort is the primitive case of Free Will, without requiring recourse to a problematic Bergsonian "fundamental self".
