What Is the Main Subject That Metaphysics Studies?


Diego Sanchez

Metaphysics is a branch of philosophy that explores the nature of reality, including the relationship between mind and matter, existence, time and space, and causality. The main subject that metaphysics studies is the fundamental nature of reality and existence.

The Nature of Reality

Metaphysics studies the nature of reality in terms of what exists and what does not exist. It tries to answer questions like:

  • What is the universe made up of?
  • Does anything exist beyond the physical world?
  • What is consciousness?

Metaphysics explores different theories on these topics, such as materialism, idealism, dualism, and monism.

Mind-Body Problem

The mind-body problem is one of the central issues that metaphysics studies. It refers to the relationship between mind (mental processes) and body (physical processes). Some philosophers argue that mind and body are separate entities while others believe they are interconnected.

The study of metaphysics also involves exploring different aspects related to human existence, such as free will versus determinism, identity over time, and personal identity.


Causality refers to the relationship between cause and effect. Metaphysics studies this relationship by considering how events or situations come about due to causation. Philosophers investigate whether causation only occurs due to physical processes or if there are any non-physical causes as well.

In addition to these topics, metaphysics also covers various other areas such as ontology (the study of being), epistemology (the study of knowledge), ethics (the study of moral principles), and aesthetics (the study of beauty).


Metaphysics is a diverse field that examines fundamental questions about the nature of reality and existence. By exploring various theories and ideas, it helps us to understand the world around us and our place in it.

Whether you’re a philosopher or simply curious about the world, studying metaphysics can be an enriching experience that opens up new perspectives and insights.
