What Are the Metaphysics in Philosophy?


Martha Robinson

Metaphysics is a branch of philosophy that deals with the fundamental nature of reality, including the relationship between mind and matter, substance and attribute, and possibility and actuality. It seeks to answer questions about the nature of existence, reality, and causality. In this article, we will explore the concept of metaphysics in philosophy.

The Origin of Metaphysics

The term “metaphysics” was coined by the philosopher Aristotle, who used it to refer to a set of philosophical works that he compiled after his treatise on physics. These works were concerned with concepts such as being, substance, cause, and identity. Metaphysics has since become a central area of inquiry in philosophy.

The Key Concepts in Metaphysics

The key concepts in metaphysics include:

  • Being: The study of what exists.
  • Causality: The study of what causes things to exist.
  • Identity: The study of what makes something what it is.
  • Reality: The study of how things exist.

These concepts are essential to understanding metaphysical theories.

The Major Schools of Thought in Metaphysics

There are several major schools of thought in metaphysics:


Platonism is a philosophical theory that originated with Plato and holds that there is an objective realm of abstract entities that exists beyond the physical world.


Aristotelianism is a philosophical theory that originated with Aristotle and holds that everything can be explained through its material causes.


Cartesianism is a philosophical theory that originated with René Descartes and holds that knowledge comes primarily from reason rather than experience.


Existentialism is a philosophical theory that emphasizes individual freedom and choice.

The Relevance of Metaphysics Today

Metaphysics remains a crucial area of inquiry in contemporary philosophy. It continues to shape our understanding of reality and our place in the world. In addition, it has practical applications in fields such as physics, computer science, and artificial intelligence.


Metaphysics is a complex field that raises many questions about the nature of reality and existence. By exploring its key concepts and major schools of thought, we can gain a better understanding of the world around us. Whether we are philosophers or not, metaphysics continues to have relevance in our lives today.
