Thirty years ago, Robert Muller, Undersecretary to the U.N. was already urging humanity to offer the world's children a comprehensive curriculum stressing their relationship to the Earth and the Human Family. Robert Muller knew that this curriculum for the transformation of society must be made available to all the children of the world. The global implementation of this education of love and responsibility for humanity and the planet would require a unifying framework.

In response to these requirements, he outlined The World Core Curriculum and assembled the discrete branches of science, the arts, and humanities under the auspices of four interpenetrating spheres of life. The World Core Curriculum approaches every subject imaginable as a dynamic part of the following Four Harmonies (Our Planetary Home and Place in the Universe; The Human Family; The Miracle of Individual Human Life; Our Place in Time).
