Ontology vs. Epistemology: What's the Difference?
Edited by Aimie Carlson || By Harlon Moss || Updated on October 14, 2023
Ontology is the study of what exists. Epistemology is the study of knowledge and justified belief.
Key Differences
Ontology pertains to the philosophical study of being or existence, exploring various kinds and structures of entities that inhabit our world. Epistemology, in contrast, probes into the nature, origin, and scope of knowledge, inquiring how we come to know what we know. Each reflects on a distinct segment of philosophical inquiry, yet they intertwine when exploring broader conceptual schemas.
With ontology, inquiries delve into whether entities within certain categories exist and the nature of said existence. Epistemology, however, would ask how we can know whether such entities exist, emphasizing the methods and justifiability of such knowledge claims. Thus, ontological discussions might revolve around entities, while epistemological debates center on our conceptual grasp and certainty regarding them.
Ontology seeks to categorize and provide clarity on the types and hierarchies of existence, venturing into realms such as materialism or idealism. On the other side, epistemology discerns our means of obtaining knowledge about these entities and categories, dissecting the reliability and limitations of our cognitive processes and evidentiary systems.
Ontology, when discussed in computing or information science, relates to a set framework or an explicit specification of a conceptualization. Conversely, epistemology is pivotal in discussions around artificial intelligence, focusing on how machines might acquire, process, and utilize knowledge, reflecting divergent considerations within varied contexts.
Engagements with ontology frequently broach metaphysical debates, dissecting the nature of reality and examining the categories into which various entities are placed. Epistemology, however, navigates through the waters of belief, truth, and justification, fostering explorations into how we validate our knowledge about reality, thereby offering another lens through which to comprehend our world.

Is ontology always related to philosophy?
While deeply rooted in philosophy, ontology also finds relevance in information science, where it helps in structuring and categorizing data.
Can ontology influence epistemology?
Yes, one’s ontological perspectives on what exists can influence their epistemological stance on how things are known and understood.
How does epistemology evaluate knowledge?
Epistemology evaluates knowledge by examining the justification, truth, belief, and reliability of information and how it's acquired.
Can ontology be applied to artificial intelligence?
Yes, in artificial intelligence, ontology helps in defining and categorizing knowledge within systems to aid in information management and retrieval.
Does ontology delve into non-material entities?
Yes, ontology explores both material and non-material entities, including abstract concepts like numbers and properties.
What are key questions in epistemology?
Key questions in epistemology involve understanding the origin, nature, and limits of knowledge, and what constitutes as justified belief.
How does ontology engage with the concept of reality?
Ontology engages with reality by exploring and categorizing the entities that exist within it and by probing the nature and structure of existence itself.
How does epistemology address the concept of belief?
Epistemology investigates belief by exploring what constitutes belief, how beliefs relate to truth, and how beliefs can be justified.
In what way does epistemology intersect with science?
Epistemology intersects with science by exploring how scientific knowledge is acquired, validated, and understood, and discussing the reliability of scientific methods.
What are some key debates in epistemology?
Key debates in epistemology may revolve around the sources of knowledge, the standards of belief justification, and the nature of truth.
Is skepticism an aspect of epistemology?
Yes, skepticism, which questions the certainty and reliability of knowledge, is a significant area within epistemological discussions.
What is an example of an ontological question?
An ontological question might be: "Do numbers exist independently of human thought?"
How does empirical evidence relate to epistemology?
Empirical evidence is vital in epistemology as it relates to knowledge derived from sensory experience and how it’s understood and validated.
Is ontology concerned with physical or metaphysical entities?
Ontology is concerned with both physical entities (like objects) and metaphysical ones (like concepts or properties).
Can an individual's ontology influence their worldview?
Absolutely, an individual’s ontology, or understanding of what exists, significantly shapes their worldview and beliefs about reality.
Is certainty a major concern in epistemology?
Yes, epistemology often deals with the concept of certainty, exploring when and how knowledge claims can be considered certain or indubitable.
