Key Differences
Epistemology delves into questions about the nature, origin, and limits of human knowledge, addressing issues like justification, belief, and truth, whereas metaphysics investigates fundamental questions about what exists, including concepts like being, substance, cause and effect, and possibility.
While epistemology focuses on understanding how we can acquire knowledge and differentiate between justified belief and opinion, metaphysics is concerned with the underlying structure of reality, examining how things exist and relate to each other beyond the physical realm.
Epistemology often deals with the methods and validity of perception, reason, and testimony as sources of knowledge, examining the criteria for what constitutes knowledge, while metaphysics deals with more abstract questions such as whether abstract concepts like numbers or moral values have real existence.
The intersection of epistemology and metaphysics can be seen in debates about whether the nature of reality affects how we can know things, with some philosophical perspectives arguing that our understanding of metaphysical truths influences our epistemological views.

What does metaphysics cover?
Metaphysics covers the foundational questions about the nature of reality, including the study of existence, objects and their properties, space and time, cause and effect, and possibility.
What are some practical applications of epistemology?
Epistemology has practical applications in areas such as science (understanding the nature and limits of scientific knowledge), education (how we teach and learn), and information theory (how information is quantified and understood).
