World order can be founded only on an unshakable consciousness of the
oneness of mankind, a spiritual truth which all the human sciences confirm.
Anthropology, physiology, psychology, recognize only one human species, albeit
infinitely varied in the secondary aspects of life. Recognition of this truth
requires abandonment of prejudice—prejudice of every kind—race, class,
colour, creed, nation, sex, degree of material civilization, everything which
enables people to consider themselves superior to others.
