Plato's philosophy in his theory of forms talks about the existence of a reality beyond the physical world and stated that this physical world is merely a reflection of the real world. This theory is an idea of Plato's interpretation of the world and its real form.

Clarity
To understand Plato's idea of the real world, one must know about the two realms- the physical realm and the spiritual realm. He defined this physical realm as the things or stuff which we can see, touch and interact in our lives as a part of our daily routine, he believed that the physical realm is delusional and is not more than a reflection of the real realm or the spiritual realm. He referred to this spiritual realm as the Realm of Forms, he stated that the realms of Forms exists far away from the material world and it is the only truest and purest form of the world.

Points of discussion
Plato assumed that every object is fundamentally or in reality a demonstration of the Form and the experiences were the shadows that impersonate the Form. This means that objects, in reality, are the instant images of the Form under different situations. He explained this through the allegory of the cave, where the prisoners only live in what they think is a real world, but really it is a shadow of reality.

According to Plato, the Forms are the core of the various objects which means Form are the ideals or the qualities that an object must have so it can be considered that type of object. For ex- If we are asks to bake some cakes, we have to satisfy all the essentials or ingredients and when cakes are being baked, we might have cakes of different flavours, colours or sizes but the idea of cake is the one and these different kinds of cakes are just a manifestation of the Form of cake (cakeness). Plato also held that the world of Forms is an abstract of our world and this physical world is the essential basis of reality.

The Forms does not belong to any particular time, in fact, the Forms exist independently of time, their existence is not more than the ideas of human minds, the Forms are the roadmap to perfections and they are considered perfect because of their uniformity.

Criticism
In the theory of Forms, Plato believed that something can't be real if not permanent, which sounds rigid and it shows a lack of flexibility with the changes and as the Forms are just the ideas of the human minds, then there are chances that the ideals or standards which are supposed to be uniform to define perfection can vary from one person to another person then how can it be permanent and who will define the criteria of perfection?

For ex- Humans can be white, black, tall or short, but who'll decide who is or what constitutes an ideal Form of human, let's suppose we let a white human decide the Ideal form of race maybe for him white is an ideal but it is not important that other will accept it.
