Pasigraphy, a proposed language for ontology

[John F Sowa]

An article in 1898, which proposed a universal formal notation called passigraphy, promoted the adoption of formal logic as a universal notation for science. 

"The following article by Ernst Schröder originally appeared in The Monist, vol. 9, 1899. This copy was extracted from a book digitized by Google. The word pasigraphy, derived from Greek pasi [for all] and graphô [write], was a proposed term for a universal written scientific language. The resulting language, based on work by Boole, DeMorgan, Peirce, Schröder, and Peano, evolved into the modern versions of symbolic logic. Note that Schröder mentioned Frege, but he and Peano had a low opinion of Frege’s notation. Whitehead and Russell attended the congress held in Paris in 1900, and they adopted Peano’s modifications to Peirce-Schröder notation for their three-volume Principia Mathematica."

I had posted a copy of that article on my website:  https://www.jfsowa.com/logic/es99.pdf .

But that was so long ago that I had forgotten it.   Jean Francis Michon reminded me of it, and I realized its relevence to recent discussions.  It is also a reminder that Peirce's notation for logic is the one that Peano, Whitehead, and Russel adopted for the logic of the 20th century.

Common Logic (CL) is a 21st C extension that supports quantifiers that range over functions and relations while retaining the simplicity and efficiency of FOL computation.

Note: pasi- is the dative case of the Greek pan  Therefore, pasigraphy would mean writing ffor all .  Eighteenth century authors knew Greek and Latin.
