...Whilst on board the Beagle I was quite orthodox, and I remember being heartily laughed at by several of the officers... for quoting the Bible as an unanswerable authority on some point of morality... But I had gradually come by this time, i.e., 1836 to 1839, to see that the Old Testament from its manifestly false history of the world, with the Tower of Babel, the rainbow at sign, &c., &c., and from its attributing to God the feelings of a revengeful tyrant, was no more to be trusted than the sacred books of the Hindoos, or the beliefs of any barbarian....By further reflecting that the clearest evidence would be requisite to make any sane man believe in the miracles by which Christianity is supported, (and that the more we know of the fixed laws of nature the more incredible do miracles become), that the men at that time were ignorant and credulous to a degree almost uncomprehensible by us, that the Gospels cannot be proved to have been written simultaneously with the events, that they differ in many important details, far too important, as it seemed to me, to be admitted as the usual inaccuracies of eyewitnesses; by such reflections as these, which I give not as having the least novelty or value, but as they influenced me, I gradually came to disbelieve in Christianity as a divine revelation. The fact that many false religions have spread over large portions of the earth like wild-fire had some weight with me. Beautiful as is the morality of the New Testament, it can be hardly denied that its perfection depends in part on the interpretation which we now put on metaphors and allegories.But I was very unwilling to give up my belief... Thus disbelief crept over me at a very slow rate, but was at last complete. The rate was so slow that I felt no distress, and have never since doubted even for a single second that my conclusion was correct. I can indeed hardly see how anyone ought to wish Christianity to be true; for if so the plain language of the text seems to show that the men who do not believe, and this would include my Father, Brother and almost all of my friends, will be everlastingly punished. And this is a damnable doctrine.
The Biblical writers not only had no knowledge of these things, but they had a perverted concept of life and the universe. Their concept was that man was a victim of blood pollution and his only salvation was by a blood atonement.I remember once seeing a small pamphlet entitled, 'What the Bible Teaches about Morality.' On opening the little booklet, it was discovered to be nothing but blank pages! Another such pamphlet might very appropriately be published entitled, 'What the Bible Reveals about Disease, Medicine and Health,' and blank pages should be used for all the Bible contains about these vital subjects.On the contrary, these benefits have been denounced by the believers in the Bible, and by the representatives of the Bible's deity as being contrary to 'God's Plan.' Does not the Bible plainly state that only by the sweat of his brow is man to labor for the bread he eats? Here is the exact Biblical quotation: 'In the sweat of thy face thou shalt eat bread...' and why? Only because he sought knowledge.And does not the Bible God place a curse upon man for the knowledge that has been such a solace and benefit to him? Here is another exact Biblical quotation: '... cursed be the ground for thy sake; in pain thou shalt eat of it all the days of thy life.'The Bible is a lie.It is a fake and a fraud.I denounce this book and its God. I hold it in utter detestation.Every man and woman who has contributed to the relief of the pain and suffering of humanity has been an infidel to the Bible God! Every new invention, every new discovery for the benefit of man violates these Biblical edicts!I say, seek knowledge—defy this tyrant God—it is your only salvation.
You are to make up your mind whether it is to be God or man. Whether you are to be free or a slave. Whether it is to be progress or stagnation.As long as man loves a phantom in the sky more than he loves his fellow man, there will never be peace upon this earth; so long as man worships a Tyrant as the "Fatherhood of God," there will never be a "Brotherhood of Man."You must make the choice, you must come to the decision. Is it to be God or Man? Churches or Homes—preparation for death or happiness for the living?If ever man needed an example of the benefit of the one against the other, he need but read the pages of history for proof of how religion retarded progress and provoked hatred among the children of men.When theology ruled the world, man was a slave. The people lived in huts and hovels. They were clad in rags and skins; they devoured crusts and gnawed bones; the priests wore garments of silk and satin; carried mitres of gold and precious stones, robbed the poor and lived upon the fat of the land!Here and there a brave man appeared to question their authority. These martyrs to intellectual emancipation slowly and painfully broke the spell of superstition and ushered in the Age of Reason and the Dawn of Science.Man became the only god that man can know.He no longer fell upon his knees in fear.He began to enjoy the fruits of his own labor.He discovered a way to relieve himself from the drudgery of continuous toil; he began to enjoy a few comforts of life—and for the first time upon this earth he found a few moments for happiness. It is far more important to learn how to live than to learn how to pray.A new day and a new era dawned for him. His labors produced enormous dividends. He looked at the sky for the first time and saw that it was blue! He searched the heavens and found no God. He no longer feared the manifestations of nature.
