"Knowing is the task of Subjects, not of objects. It is as a subject, and only as such, that a man or woman can really know. In the learning process the only person who really learns is s/he who appropriates what is learned, who apprehends and thereby re-invents that learning; s/he who is able to apply the appropriated learning to concrete existential situations. On the other hand, the person who is filled by another with "contents" whose meaning s/he is not aware of, which contradict his or her way of being in the world, cannot learn because s/he is not challenged."
