Every existent has 7 characteristics:
1) It is a member of a class of things of its kind.
2) Its existence has necessary and sufficient conditions i.e. causes.
3) It has an environment and spatial location.
4) It is in process and motion.
5) It is structured in some way.
6) It has relations with other things, direct and indirect.
7) It depends on communications.
For human beings, 3) 6) & 7) are especially complex and indeed are the bases of culture.
