List, Gary: 

Excellent post.  Thank you!
Below, I will postulate how Gary’s interpretation of this semantic distinction 
illates to syntactical distinctions of the natural philosophy of the natural 
sciences and natural diagrammatic mathematics resting on CSP’s notion of the 
symbolic relationships between icons and rhema.

This is of particular importance in view of the foundations of CSP’s notions of 
foundations of arguments (the linguistics of the trichotomistic descriptions of 
phenomena resting on semiotics).   

In the view of alternative views of Husserl / Cantor and Frege that dominate  
the axiomatic structures of nominalism, the contrasts and comparisons of 
meanings of the two quasi-parallel notions, phenomenology and phaneroscopy.

In particular, it not merely separates two philosophical perceptions of numbers 
and continuity, it widens the gap between truth functions based on the 
languaging of the definitions of the trichotomistic terms and the truth 
functions resting on the Whitehead and Russell’s notion of mathematical logic.

Further, this distinction in meaning is highly relevant to the contradictions 
of “liar’s paradox” of Russell (along with his notion of atomic and molecular 
sentences) and the realism of CSP composing  categorical "molecular sentences” 
by compounding Rhema and Decisions.
  
CSP’s logical compositions of arguments from rhematic terms and dicisignated 
terms can be used to define symbols and lattices of symbols representing 
legisigns because the truth of arguments rests on icons, not axioms. This view 
is constructed from the composition of atoms into categories of molecules.

The notions of scientific imagination necessary to relate the mathematical 
operations relating semiosis to the enumerable forms representing legi-signs 
cohere smoothly with diagrammatic forms would be specific examples of 
phaneroscopy.   

Perhaps someone who understand the meaning of the “contradictory term” of 
“phenomenology”, could imagine a counter-example relevant to the logics of the 
natural sciences?

Cheers

Jerry
