Thank you so much, unspun, for posting the definitions of apodictic (apodeixis) amd epidictic (epideixis). They still might strike some readers as a tad confusing (those darned Greeks!).

Maybe it would simplify things a bit if we understand the apodictic as that type of reason that relies on direct reference to specific objects; i.e., the type of reason used in empirical tests. Epidictic reasoning proceeds, not by direct reference, but by inference from larger contexts; i.e., the contexts in which a multiplicity of "objects" exist.

This is your "relationality" we're speaking of here, brother Arlen!
