# Chapter I: Detecting error and illusion > The purpose of education is to transmit knowledge, and yet education is blind to the realities of human knowledge, its systems, infirmities, difficulties, and its propensity to error and illusion. Education does not bother to teach what knowledge is.
>Knowledge cannot be handled like a ready-made tool that can be used without studying its nature. Knowing about knowledge should figure as a primary requirement to prepare the mind to confront the constant threat of error and illusion that parasitize the human mind. It is a question of arming minds in the vital combat for lucidity.
We must introduce and develop the study of the cultural, intellectual, and cerebral properties of human knowledge, its processes and modalities, and the psychological and cultural dispositions which make us vulnerable to error and illusion.
