What Does Metaphysics Say About the World?


Jane Flores

Metaphysics is a branch of philosophy that seeks to understand the nature of the world, reality, and existence itself. It is concerned with questions such as “What is the world made of?”

and “What is the ultimate nature of reality?” In this article, we will explore what metaphysics has to say about the world we live in.

The Nature of Reality

Metaphysics holds that there are two fundamental aspects to reality: substance and properties. Substance refers to the underlying essence of a thing, while properties are its observable characteristics. For example, gold is a substance with properties such as its color and weight.

Materialism vs Idealism

There are two main schools of thought within metaphysics: materialism and idealism. Materialists hold that only physical matter exists, while idealists believe that reality is made up entirely of ideas or mental states.

Materialism: Materialists argue that everything in the world can be explained by physical laws. According to this view, humans are just complex machines made up of atoms and molecules. Even our thoughts and emotions can be reduced to physical processes in our brain.

Idealism: Idealists argue that reality is fundamentally mental in nature. According to this view, our perceptions create the world around us. In other words, reality exists only in our minds.

The Problem of Universals

One question that has puzzled philosophers for centuries is whether abstract concepts such as “justice” or “beauty” have a real existence outside our minds. This problem is known as the problem of universals.

Some philosophers hold that these abstract concepts exist independently of human thought – they are called realists. Others argue that they exist only as ideas in our minds – they are called nominalists.

Causation and Determinism

Another important area within metaphysics is the study of causation and determinism. Causation refers to the relationship between cause and effect, while determinism holds that events are predetermined by prior causes.


Metaphysicians debate whether causation is a real feature of the world or just a useful way of describing events. Some philosophers argue that causation is a fundamental feature of reality, while others believe that it is simply a human construct.


Determinism holds that all events are predetermined by prior causes. This view has important implications for free will – if everything we do is predetermined, can we truly be said to have free will?


Metaphysics is a complex and fascinating field that seeks to understand the nature of reality itself. Whether you are a materialist or an idealist, a realist or a nominalist, there is much to be gained from studying metaphysics. By exploring these questions about the world we live in, we can gain new insights into ourselves and our place in the universe.
