Unbridled nationalism, as distinguished from a sane and legitimate patriotism, must give way to a wider loyalty, to the love of humanity as a whole. Baha'u'llah's statement is: "The earth is but one country, and mankind its citizens." The concept of world citizenship is a direct result of the contraction of the world into a neighborhood through scientific advances and of the indisputable interdependence of nations. Love of all the world's peoples does not exclude love of one's country. The advantage of the part in a world society is best served by promoting the advantage of the whole. Current international activities in various fields which nurture mutual affection and a sense of solidarity among peoples need greatly to be increased.
