What Do You Need to Study for Metaphysics?


Martha Robinson

Metaphysics is a branch of philosophy that explores the fundamental nature of reality, existence, and the universe. It is a complex subject that requires a deep understanding of various concepts and ideas.

If you are interested in studying metaphysics, you need to have a solid foundation in certain areas. In this article, we will explore what you need to study for metaphysics.


Epistemology is the study of knowledge and belief. It examines how we acquire knowledge, what we can know, and how we can justify our beliefs. This field of study is essential for metaphysics because it helps us understand the nature of reality and existence.

Rationalism vs Empiricism

One of the main debates in epistemology is between rationalism and empiricism. Rationalism argues that knowledge can be acquired through reason alone, while empiricism argues that knowledge comes from experience and observation.


Ontology is the branch of metaphysics that studies existence and being. It explores questions such as: What exists?

What is real? What are the fundamental categories of reality?

Substance vs Property Dualism

One major debate within ontology is between substance dualism and property dualism. Substance dualism holds that there are two distinct types of substances in the universe: material substances (bodies) and immaterial substances (minds or souls). Property dualism holds that everything in the universe has both physical properties (such as weight) and mental properties (such as thoughts).


Cosmology is the study of the origin, evolution, and ultimate fate of the universe. It explores questions such as: How did the universe begin?

How will it end? What laws govern its behavior?

The Big Bang Theory

The Big Bang Theory is the most widely accepted scientific theory about the origin of the universe. It posits that the universe began as a single point of infinite density and temperature, which then expanded and cooled over billions of years to form the universe we know today.

Metaphysical Ethics

Metaphysical ethics is the study of moral principles and values in relation to metaphysical concepts such as existence, reality, and the nature of being.

Moral Realism vs Moral Anti-Realism

One debate within metaphysical ethics is between moral realism and moral anti-realism. Moral realism holds that there are objective moral facts that exist independently of human beliefs or opinions. Moral anti-realism holds that moral facts are either subjective or non-existent.

In conclusion, if you want to study metaphysics, you need a solid foundation in epistemology, ontology, cosmology, and metaphysical ethics. By studying these areas, you can gain a deeper understanding of the fundamental nature of reality and existence.
