QuoteHowever, if we interpret Lucretius’ concept of corpora as ‘discrete particles’ or ‘atoms’ instead of flows, his whole conceptual edifice of folding [plex] (simplex, duplex, complex, amplex) completely unravels. Atoms simply cannot fold.
I do believe that Nail is alone in interpreting corpora as "flows." Corpora is a common and simple word that means "bodies." It is used by Lucretius, among many other terms, to refer to the primary particles ("atoms" in the literal sense of fundamental uncuttable units).
The idea of "flow" will not be found in any dictionary entry for Corpora (link for example). There is no place in Latin literature where Corpora means anything close to "flows."
Similarly, although the -plex ending in simplex, duplex, etc. does indeed etymologically come from “-fold”, nevertheless simplex, and duplex are the standard Latin words for "single and double" -- and forcing an actual and literal "fold" into the idea -- beyond "single-fold" meaning "single" and "two-fold" meaning "double" -- is another unique interpretation of Thomas Nail.
