Considering these definitions:
Ontology is the philosophical study of the nature of being, becoming, existence, or reality, as well as the basic categories of being and their relations.
Epistemology is the study of knowledge and justified belief.
The act of knowing (inherent epistemological claim) itself reveals the existence of the object in consideration - (inherent ontological claim). And it is obvious as there must be an object of knowledge before knowing the object.
- Does it follow, every epistemological claim is by product of ontological claim? Or In other words, Is there any epistemological claim of an object without dealing inherently with its ontology?
