Modern education is competitive, nationalistic and separative. It has trained the child to regard material values as of major importance, to believe that his nation is also of major importance and superior to other nations and peoples. The general level of world information is high but usually biased, influenced by national prejudices, serving to make us citizens of our nation but not of the world.
