This article highlights the underlying principles in the construction of knowledge drawing on the theoretical framework postulated by Critical Pedagogy. It also stresses the importance of viewing human beings as co-creators of the world by being able to integrate new knowledge into previous knowledge and, consequently, taking an active role in this process. Conversely, when humans are not able to create new knowledge under such circumstances, they remain disconnected and simply adapt to the world.

As a result, they will be better able to learn to learn.
