Difference between Epistemology and Ontology

Table of Contents

Epistemology often includes a debate between empiricism and rationalism. Empiricism claims that knowledge can only be gained through experience. However, rationalism claims that knowledge can be acquired through reason alone. Epistemology tries to find out which one is correct, or is the truth a combination of the two.

Ontology, on the other hand, is actually a subset of metaphysics, which is in turn a branch of philosophy. Metaphysics seeks primarily to answer the question, what is reality? Its areas of investigation primarily include existence, objects and their properties, space and time, cause and effect, and possibility.

OntologyOntology deals specifically with the philosophical study of the nature of being, becoming, existence or reality. Basically, it deals with how things come into being and what kinds of things exist. In fact, the term ontology comes from the Greek ‘onto-’ meaning “being” or “that which is” with the suffix -logy, meaning ‘a logical discourse.’ Hence, ontology is literally the study of being.

In order to differentiate between them further, it can be said that ontology deals with what is true, whereas epistemology deals with figuring out that truth. It can also be said that ontology is about the nature of reality and epistemology is about the relationship between the person and that reality, i.e. how people gain knowledge or how they get to know something, as well as the different methods of gaining knowledge.

Etymology

Derived from the ancient Greek epistēmē meaning "knowledge" and the suffix -logy, meaning a logical "discourse" to"

Derived from onto-, from the Greek ὄν, on (gen. ὄντος, ontos), i.e. "being; that which is", which is the present participle of the verb εἰμί, eimí, i.e. "to be, I am", and -λογία, -logia, i.e. "logical discourse"

Study of

Much of the debate in epistemology centers on four areas:

  • the philosophical analysis of the nature of knowledge and how it relates to such concepts as truth, belief, and justification
  • various problems of skepticism
  • the sources and scope of knowledge and justified belief
  • the criteria for knowledge and justification.

Being, how things come to exist, and what is meant by existence. Questions:

  • "What can be said to exist?"
  • "What is a thing?"
  • "Into what categories, if any, can we sort existing things?"
  • "What are the meanings of being?"
  • "What are the various modes of being of entities?"
