In this dark world the human reality is the physical body. In the outside of the cavern the human reality is the soul. While each of us is identified, it is clear itself and to the others like physical bodies, while all our effort and eagerness go solely directed towards which we considered material, we will live in the dark, taking by real what it is not, unconscious of our situation and deceived by the shades of objects that others transport and that they will form our world.The liberation and ascent towards the light, constitutes the process of waking up of brings back to consciousness. It is the internal transit from a reality to another one, of the state of unconsciousness at levels more conscious than they allow to see the difference him between real and the unreal thing. The steep way that leads towards the outside of the cavern is the way of the self-knowledge and of the development of it brings back to consciousness until getting to create the capacity to directly watch the Sun that stops Plato symbolizes the source of all Light and Knowledge. One of the most interesting points of the story of Plato is how it begins, before initiating the allegory writes: compares with the following scene the state in which, with respect to the education or to the lack of her, is our nature. But,of what education it speaks Plato? One does not talk about to which today we understand by so. In old Greece it was distinguished between education, that were the integral development of the soul and inner waking up, and instruction, that it had like unique objective to provide knowledge adapted for the exercise of a profession u office. As easily it is possible to be verified at our time does not exist an education system rather but and in the best one of the cases of instruction.
