of races, of nations, of East and West, the reconciliation of
religion and science, the eradication of prejudices and superstitions,
the equality of men and women, the establishment of
justice and righteousness, the setting up of a supreme international
tribunal, the unification of languages, the compulsory
diffusion of knowledge—these, and many other teachings like
these, were revealed by the pen of Bahá’u’lláh during the latter
half of the nineteenth century in innumerable books and
epistles several of which were addressed to the Kings and Rulers
of the world.
