The most religious nations have been the most immoral, the cruelest and the most unjust. Italy was far worse under the Popes than under the Cæsars. Was there ever a barbarian nation more savage than the Spain of the sixteenth century? Certainly you must know that what you call religion has produced a thousand civil wars, and has severed with the sword all the natural ties that produce "the unity and married calm of States." Theology is the fruitful mother of discord; order is the child of reason. If you will candidly consider this question—if you will for a few moments forget your preconceived opinions—you will instantly see that the instinct of self-preservation holds society together. Religion itself was born of this instinct. People, being ignorant, believed that the Gods were jealous and revengeful. They peopled space with phantoms that demanded worship and delighted in sacrifice and ceremony, phantoms that could be flattered by praise and changed by prayer. These ignorant people wished to preserve themselves. They supposed that they could in this way avoid pestilence and famine, and postpone perhaps the day of death. Do you not see that self-preservation lies at the foundation of worship? Nations, like individuals, defend and protect themselves. Nations, like individuals, have fears, have ideals, and live for the accomplishment of certain ends. Men defend their property because it is of value. Industry is the enemy of theft. Men, as a rule, desire to live, and for that reason murder is a crime. Fraud is hateful to the victim. The majority of mankind work and produce the necessities, the comforts, and the luxuries of life. They wish to retain the fruits of their labor. Government is one of the instrumentalities for the preservation of what man deems of value. This is the foundation of social order, and this holds society together.
Religion has been the enemy of social order, because it directs the attention of man to another world. Religion teaches its votaries to sacrifice this world for the sake of that other. The effect is to weaken the ties that hold families and States together. Of what consequence is anything in this world compared with eternal joy?
You insist that man is not capable of self-government, and that God made the mistake of filling a world with failures—in other words, that man must be governed not by himself, but by your God, and that your God produces order, and establishes and preserves all the nations of the earth. This being so, your God is responsible for the government of this world. Does he preserve order in Russia? Is he accountable for Siberia? Did he establish the institution of slavery? Was he the founder of the Inquisition?
You answer all these questions by calling my attention to "the retributions of history." What are the retributions of history? The honest were burned at the stake; the patriotic, the generous, and the noble were allowed to die in dungeons; whole races were enslaved; millions of mothers were robbed of their babes. What were the retributions of history? They who committed these crimes wore crowns, and they who justified these infamies were adorned with the tiara.
You are mistaken when you say that Lincoln at Gettysburg said: "Just and true are thy judgments, Lord God Almighty." Something like this occurs in his last inaugural, in which he says,—speaking of his hope that the war might soon be ended,—"If it shall continue until every drop of blood drawn by the lash shall be paid by another drawn with the sword, still it must be said, 'The judgments of the Lord are true and righteous altogether.'" But admitting that you are correct in the assertion, let me ask you one question: Could one standing over the body of Lincoln, the blood slowly oozing from the madman's wound, have truthfully said: "Just and true are thy judgments, Lord God Almighty"?
Do you really believe that this world is governed by an infinitely wise and good God? Have you convinced even yourself of this? Why should God permit the triumph of injustice? Why should the loving be tortured? Why should the noblest be destroyed? Why should the world be filled with misery, with ignorance, and with want? What reason have you for believing that your God will do better in another world than he has done and is doing in this? Will he be wiser? Will he have more power? Will he be more merciful?
When I say "your God," of course I mean the God described in the Bible and the Presbyterian Confession of Faith. But again I say, that in the nature of things, there can be no evidence of the existence of an infinite being.
An infinite being must be conditionless, and for that reason there is nothing that a finite being can do that can by any possibility affect the well-being of the conditionless. This being so, man can neither owe nor discharge any debt or duty to an infinite being. The infinite cannot want, and man can do nothing for a being who wants nothing. A conditioned being can be made happy, or miserable, by changing conditions, but the conditionless is absolutely independent of cause and effect.
I do not say that a God does not exist, neither do I say that a God does exist; but I say that I do not know—that there can be no evidence to my mind of the existence of such a being, and that my mind is so that it is incapable of even thinking of an infinite personality. I know that in your creed you describe God as "without body, parts, or passions." This, to my mind, is simply a description of an infinite vacuum. I have had no experience with gods. This world is the only one with which I am acquainted, and I was surprised to find in your letter the expression that "perhaps others are better acquainted with that of which I am so ignorant." Did you, by this, intend to say that you know anything of any other state of existence—that you have inhabited some other planet—that you lived before you were born, and that you recollect something of that other world, or of that other state?
Upon the question of immortality you have done me, unintentionally, a great injustice. With regard to that hope, I have never uttered "a flippant or a trivial" word. I have said a thousand times, and I say again, that the idea of immortality, that, like a sea, has ebbed and flowed in the human heart, with its countless waves of hope and fear beating against the shores and rocks of time and fate, was not born of any book, nor of any creed, nor of any religion. It was born of human affection, and it will continue to ebb and flow beneath the mists and clouds of doubt and darkness as long as love kisses the lips of death.
