In this good opportunity, I will discuss the object of ontology and metaphysics studies and the types of ontology streams.
Ontology is always concerned with the question "what"
Ontology study objects:
1. Monoism (1 nature of origin)
2. Twoism (2 types of source origin)
3. Pluralism (various forms of reality)
4. Nihilism (a doctrine that does not recognize positive alternatives)
5. Agnosticism (understanding negation)
Metaphysics studies the concept of reversal, for example which occurs in the real or unreal, which can be felt or can not be felt, and others.
Ontology streams:
1. Realism: based on reason and mind
2. Idealism: thinking is one of them is true
3. Existentialism: centered on humans who are responsible for their will without knowing right or wrong
