This may not be the answer you're looking for, but it might be of
general interest to point out that one of the earliest researchers
with an algebraic approach to *many-valued logics*, Grigore Moisil
(https://en.wikipedia.org/wiki/Grigore_Moisil), used to call them
"non-Chrysippian logics", precisely for the reasons alluded in the
above quote.

In this respect, by the way, you might want to check the book "Essais
sur les logiques non chrysippiennes", which has the following table of
contents:

Maybe someone out there will have a link to a fully scanned copy of this book.

Yours,
Joao Marcos
