In modern chemistry, the principle icons are chemical structures that correspond exactly with indices, rhemata, decisigns, arguments, legisigns, the symbols of the chemical table of elements and the sinsign as the source of qualisigns. Furthermore, chemical icons, at a deeper abstract level, are a direct consequence of physical laws and physical experimentation and chemical mathematics of the atomic numbers. Chemists call an icon a chemical identity and, and as a class, chemical identities are the basis for the formal logic of mathematical chemistry and a form of logic of relatives developed from the conceptualization of matter as atoms with unique properties. CSP (1839-1914?) died long before chemists learned construct chemical icons from the indices representing electrical units and integers. Cheers Jerry
