John:

If you find your arguments below to be compelling, then the issue is no longer 
a issue for you.

These arguments are not compelling to me.  See comment in text.

Mysterious?  Strange choice of words.

Huh?  I do not understand why the usage of another author a century later is 
relevant to another's usage a century earlier.

Huh?  CSP's usage start with the generative operation of crossing two lines.

Both examples are of interest as generative logical operations, not 
degenerative operations. 
In the case of genesis of isomers, I see no reason to separate out optical 
isomers as a special case. 
Every form of isomerization in the notation of chemisty is of a different sort 
or kind with respect to a given molecular formula. 

John, the following question comes to mind:

As you are probably aware, bacteria (such as E, coli) can generate their 
internal carbon structures from many, many different carbon sources. 
Furthermore, they have a "pecking order" for selecting one exterion carbon 
source before another for internal constructions.  For example, one isomer of 
hexose before a different isomers..

 Is this generacy or degeneracy?

A second question is similar.  If a biological specie emerges as a consequence 
of loss of functionality, would you consider this generacy or degeneracy?

Cheers
