We must destroy nationalism.
“As long as the child breathes the poisoned air of nationalism, education in world-mindedness can produce only precarious results. As we have pointed out, it is frequently the family that infects the child with extreme nationalism. The school should therefore use the means described earlier to combat family attitudes that favor jingoism. . . . We shall presently recognize in nationalism the major obstacle to development of world-mindedness.”
