There is a basic knowledge which is necessary for every human being; until a person has acquired this basic knowledge, all other kinds of knowledge will be harmful for him.
Socrates told his students that in good systems of education, there is a certain limit you should not go beyond. In geometry, he said, it is enough to know how to measure the land when you want to sell it or buy it, or how to share an inheritance, or to divide work among workers. He did not like too many sophisticated sciences; though he knew all of them. He said that sophisticated knowledge requires an extra effort that takes the student's time from the most basic and the most important human pursuit: moral perfection.
Divert your gaze from the world of lies. Do not trust your feelings. Only in yourself, only in your impersonal self, can you find the eternal.
— Dhammapada, a book of Buddhist Wisdom
