Apart from technological factors, unification of the planet is exerting other, even more direct effects on thought. It would be impossible to exaggerate, for example, the transformative impact on global consciousness that has resulted from mass travel on an international scale. Greater still have been the consequences of the enormous migrations that the world has witnessed during the century and a half since the Báb declared His mission. Millions of refugees fleeing from persecution have swept like tidal waves back and forth across the European, African and Asiatic continents, particularly. Amid the suffering such turmoil has caused, one perceives the progressive integration of the world’s races and cultures as the citizenry of a single global homeland. As a result, people of every background have been exposed to the cultures and norms of others about whom their forefathers knew little or nothing, exciting a search for meaning that cannot be evaded.
