A set of principles subsumes and causes all activities. Principles are uncaused and intrinsic. Activities are caused and extrinsic.
Nature is a set of activities organized intrinsically by a set of principles.
There are five principles. The universe is produced, maintained and dissolved by each individual every moment. The engine is will. There is widespread but imperfect consensus about what to produce, maintain and dissolve and large but limited choice about what can be produced, maintained and dissolved. All time-fields are concurrent.
