"Effective education should lead to a sense of synthesis and of recognition of the bonds and relations stretching beyond family ties, to include the local community, then the nation, and eventually encompassing world relationships, and thus all of humanity. This training should begin by suitable preparation for parenthood and good citizenship, but should not end before the pupil has been brought to an evaluation of the position and responsibilities he carries in relation to the rest of the world of men. This training would basically be psychological, and should convey a reasonable understanding of man's own constitution and functioning, and how this relationship stretches beyond the self, eventually becoming all-inclusive. He should also be made aware that the main causes of disharmony are based on selfishness, possessiveness, intolerance, separativeness and the lack of love."
