All sciences have a hidden ontology and all ontologies anticipate a knowledge .
In developing an answer to this question we will concentrate on the ontological aspect before shifting to the epistemological question of how the properties of human livelihood make it an object of knowledge for us. This is not an arbitrary order of development. It reflects the strong proposition that it is the nature of objects that determines their cognitive possibilities for us. Our reason for examing ontology is that it tells us about the general structures of our world. We can contrast these most general structures with the structures produced by other worldviews.
