List: The following differentiating opinions are significant to the foundations of CSP Logic and philosophy of science, and, by pragmatic extension, to his philosophy more generally conceived.

The open question is how did his educational history contribute to his future developments He understood the chemical notations of his day as both a mathematical system and material system in his view of “thing, representation, and form”. CSP’s philosophy of pragmaticism is grounded on his opinions relating scientific thought to non-scientific thought. Historically, the notation for chemistry underwent historic changes during CSP lifespan as a consequence of the rapid development of organic chemistry. Organic chemistry can NOT be notated in the symbol system devised by Berzelius (1779-1848) for inorganic chemistry. That is, salts are a composite of two or more elements as electrical particles with polar opposition. This created substantial logical tensions for CSP which he never resolved, although he worked at the challenge for decades. CSP recognized that the logic of chemistry was different from the usual logic of mathematics because of the conflict between the symbol system devised by organic chemists necessarily required icons and indexes that differ from the symbol system for inorganic salts. Most organic chemicals are not ions and lack the physical properties of ions. So, Jon, I both concur and do not concur with your post in the following ways. I do not concur with the following statement > That statement is the very epitome of the retrograde motion that has occurred > in the understanding of Peirce's logic and semiotics in recent years. I do concur with the second sentence: > If that really is Frederik's thesis then you have just saved me the trouble > of an utterly futile discussion. Yes, it would be futile to attempt to fit your interpretation of CSP logic of relatives into Frederik's thesis. I will post more about the details of Natural Propositions and the relationships to natural logic shortly, as it relates directly to the International system of units for scientific measures.
