Theory of Forms

Plato's theory of forms is a philosophical idea that suggests there are two realms of existence: the visible world and the intelligible world. The visible world is the one we perceive with our senses, and it is full of changing and imperfect things. The intelligible world is the one we access with our reason, and it is composed of eternal and perfect forms. These forms are the essences or ideals of everything that exists in the visible world, such as beauty, justice, goodness, etc. Plato believed that the forms are the only true objects of knowledge, and that we can only approach them through rational inquiry.

One way to illustrate Plato's theory of forms is by using his famous allegory of the cave¹. Imagine a group of prisoners who have been chained in a dark cave since birth. They can only see the shadows of objects projected on the wall by a fire behind them. They think that these shadows are the reality, and they have no idea that there is a world outside the cave. One day, one of the prisoners escapes and sees the real objects that cast the shadows. He also sees the sun, which is the source of light and truth. He returns to the cave and tries to tell his fellow prisoners what he has seen, but they do not believe him and think he is crazy.

Plato used this allegory to show that most people are like the prisoners in the cave, who only see the appearances of things and not their true forms. They are deceived by their senses and opinions, and they do not seek the higher knowledge that comes from reason. Only a few people, like the escaped prisoner, are able to free themselves from their ignorance and reach the intelligible world, where they can contemplate the forms. These people are the philosophers, who Plato considered to be the best rulers for a just society.
