"Allegory of the Cave"
            
             The prison dwelling and the visible realm are compared to one another in the first
             sentence of the text. The realm is dark, with the exception of a small, well-kept fire. This
             burning fire is almost a representation of the burning sun that shines in the outer world. This sun
             is interpreted as the "idea of the good." The fire inside the cave helps guide the prisoners to use
             their senses. Without it, they would see nothing, not even their own shadows glowing on the
             wall. The physical objects that the prisoner saw were mere illusions. We should never trust
             what we see with just our eyes, because illusions will be the result. Then, we would get

             constantly changing. This is why the visible is just an opinion. We should, instead, only believe
             in things that are long-lasting, those that are non-physical, non-dimensional. They are just ideas,
             they are full of knowledge.
             In the second sentence, the prisoner's upward journey can only be seen in ideas or forms.
             This is known as the intelligible realm. We find these ideas in the rational part of the soul. The
             outside would is full of reality, but most importantly, it consists of something the prisoner has
             never before encountered. This is found outside of the cave, the only home he has ever known.
             This is called knowledge. The prisoner does have a downfall of thi...
