Let us acknowledge at the outset the magnitude of the ruin that the human race has brought upon itself during the period of history under review. [20th Century] The loss of life alone has been beyond counting. The disintegration of basic institutions of social order, the violation—indeed, the abandonment—of standards of decency, the betrayal of the life of the mind through surrender to ideologies as squalid as they have been empty, the invention and deployment of monstrous weapons of mass annihilation, the bankrupting of entire nations and the reduction of masses of human beings to hopeless poverty, the reckless destruction of the environment of the planet—such are only the more obvious in a catalogue of horrors unknown to even the darkest of ages past. Merely to mention them is to call to mind the Divine warnings expressed in Bahá’u’lláh’s words of a century ago: “O heedless ones! Though the wonders of My mercy have encompassed all created things, both visible and invisible, and though the revelations of My grace and bounty have permeated every atom of the universe, yet the rod with which I can chastise the wicked is grievous, and the fierceness of Mine anger against them terrible.”
