Things have properties. It means that one thing can have many properties.
Properties are, however, nested, so that one property has a spectrum of properties, while things are nested in each other so that one thing consists of many things.
It means that not both things and properties can be singular, because if they could, then a single thing could have contradictory properties, but instesd thus that only things can be singular.
This fact contradicts cladistics’ and particle physics’ claims (claim) that both things and properties can be singular. It means that cladistics and particle physics are wrong.
