"To consider the world in its length and breadth, its various history, the many races of man, their starts, their fortunes, their mutual alienation, their conflicts; and then their ways, habits, governments, forms of worship; their enterprises, their aimless courses, their random achievments, and acquirements, the impotent conclusion of long-standing facts, the tokens so faint and broken of a superintending design, the blind evolution of what turn out to be great powers or truths, the progress of things, as if from unreasoning elements, not toward final causes, the greatness and littleness of man, his far-reaching aims, his short duration, the curtain hung over his futurity, the dissapointments of life, the defeat of good, the success of evil, physical pain, mental anguish, the prevalence of sin, the pervading idolatries, the corruptions, the dreary hopeless irreligion, that condition of the whole race, so fearfully yet exactly described in the Apostle's words, "having no hope and without God in the world," - all this is a vision to dizzy and appall; and inflicts upon the mind the sense of a profound mystery, which is absolutely beyond human solution."
— John Henry Newman

"Imagine that you are creating a fabric of human destiny with the object of making men happy in the end...but that it was essential and inevitable to torture to death only one tiny creature...And to found that edifice on its unavenged tears: would you consent to be the architect on those conditions? Tell me, and tell me the truth!"
— Fyodor Dostoyevsky
