Is Reality an Illusion?: Science, Philosophy, and the Illusion of Perception

(ORDO NEWS) — Plato, as well as his teacher Socrates, are often recognized as the minds that laid the foundation for the Western philosophical tradition as we know it today.

Plato’s theory of forms and the “Allegory of the Cave” are not only interesting in the history of philosophy, but also relevant for modern philosophy and science.

So relevant that a new theory in physics postulates a concept very similar to Plato’s.

But before we get to that, let’s go back for a moment to Plato’s theory of forms…

Is reality an illusion?

For Plato, the perceived world is not the ultimate reality. The objects of daily life are but shadows of forms.

In The Allegory of the Cave, Plato compares our false perception of the world of experience to the idea of ​​shadows on a wall.

Imagine that you are chained in a cave so that you can only look at the wall in front of you. You cannot look back or turn your head in any direction.

Behind you, in the distance, a fire burns. There are various objects in front of the fire. The shadows of these items are displayed on the wall in front of you.

Not only would you be bored, you would be living in an illusion…

If you did not know any other life than life in a cave, the shadows would seem to you real objects of reality.

They would not be mere phantoms or shadows of something more real, they would seem very real, and they would constitute your reality.” For Plato, this is similar to our everyday experience.

Just as the shadows on a wall are not the ultimate reality of the objects from which those shadows emanate, the objects of everyday experience are also not a true or perfect reflection of the ultimate reality.


Forms, being the ultimate reality, are universal, timeless and perfect. The objects of experience are imperfect imitations of forms.

For example, a mathematical triangle is perfect in abstraction, but perfect triangles do not exist in nature. The triangles of our experiential world are only imperfect reflections of the ideal form of a triangle.

Just as the triangles of experience are only imperfect reflections of the true shape of the triangle, so it is with every object of perception, including things like beauty.

Beauty has an ideal form, from which the beautiful things we perceive are only imperfect reflections.

Therefore, the world as we perceive and experience it is only an imperfect reflection of the ultimate reality of forms.

Information realism

Although this is an ancient theory, modern physics has radically updated this idea. This idea is called information realism and was recently covered in a Scientific American article.

Information realism claims that the objects of everyday experience are not part of the ultimate reality, but are an illusion of perception…

Instead, mathematics or information itself is considered to be the true or ultimate reality.

The matter that allows us to perceive objects in everyday experience is only a derivative of the underlying information.

The information that underlies the objects of experience is the ultimate reality. Everything else is just an illusion of perception.

Information realism, like Platonic form theory, uses the epistemological method of rationalism, as opposed to empiricism, to arrive at such conclusions.

Rationalists argue that true knowledge about the world can be obtained through reason – regardless of experience.

Empiricists claim that true knowledge of the world is acquired through experience and the use of our senses.

Science and philosophy

With all this in mind, is information realism theory scientific or philosophical? I would argue that it is philosophical in nature.

In fact, many theories in modern physics seem more philosophical than scientific.

On the other hand, philosophy and science were once a joint discipline – and even the great Isaac Newton was considered a natural philosopher.

Some of the same problems that have been posed against the theory of forms can also be posed against information realism.

One such challenge concerns the idea of ​​an ultimate reality that is beyond any possible experience and is itself unknowable.

In other words, if an ultimate reality exists in a world outside our own, or if true reality is somehow outside our experience, how can we say anything meaningful about it?

How can we know what this ultimate reality is if we cannot experience it? How do we even know that there is an ideal world or ultimate reality that exists outside of our experience?

How do we know that such a reality is anything more than an abstract or mathematical artifact? How can we test these theories if the world they represent seems inaccessible?

It is difficult to find meaning in such theories that assert a reality beyond our experience. It is difficult to say anything meaningful about the ultimate reality, which is allegedly more real than our world.

But it’s ideas like these that inspire films like The Matrix, give philosophers something to think about, and can ultimately bring science and philosophy together.
