As a chemist, CSP often inscended hyle terminology into his logical corpse as he sought to extend the 15-17 th century historical usages of the meaning of the concept of a “term" . One particularity of chemical synthesis is the absence of the “negative” operators on the chemical elements. Each element is a logical constant in the language of chemistry and hence can not be negated. Yet, in the notation for chemistry it is necessary to assert and signify the absence of a chemical unit in a logical product. This could be referred to as a minimal negation in a logically consistent semantics of a chemical syntax. I have no information, either positive or negative, of the meaning that Jon intends to infer logically with his usage of this non-standard semantics. However, this semantics is obviously useful in attempting to give a logical semantics for the well-established semiosis of hyle. Cheers Jerry
