Element Element is the most primitive concept in the Predication Substrate: anything that can be the subject or object of predication. Formally, Element u = Set u - a type at universe level u. An Element makes no ontological commitment: it is neither an Entity nor a Relation, neither concrete nor abstract. It is simply something that can be talked about - classified, linked, composed. Every concept in SysFEAT is an Element at some universe level; what distinguishes concepts is the level at which they live and the Linkages they participate in. |
