Robert G. Ingersoll said this quote

Religion can never reform mankind because religion is slavery. It is far better to be free, to leave the forts and barricades of fear, to stand erect and face the future with a smile. It is far better to give yourself sometimes to negligence, to drift with wave and tide, with the blind force of the world, to think and dream, to forget the chains and limitations of the breathing life, to forget purpose and object, to lounge in the picture gallery of the brain, to feel once more the clasps and kisses of the past, to bring life's morning back, to see again the forms and faces of the dead, to paint fair pictures for the coming years, to forget all Gods, their promises and threats, to feel within your veins life's joyous stream and hear the martial music, the rhythmic beating of your fearless heart. And then to rouse yourself to do all useful things, to reach with thought and deed the ideal in your brain, to give your fancies wing, that they, like chemist bees, may find art's nectar in the weeds of common things, to look with trained and steady eyes for facts, to find the subtle threads that join the distant with the now, to increase knowledge, to take burdens from the weak, to develop the brain, to defend the right, to make a palace for the soul. This is real religion. This is real worship

Nothing but truth is immortal.

~ Robert G. Ingersoll

When I became convinced that the Universe is natural – that all the ghosts and gods are myths, there entered into my brain, into my soul, into every drop of my blood, the sense, the feeling, the joy of freedom. The walls of my prison crumbled and fell, the dungeon was flooded with light and all the bolts, and bars, and manacles became dust. I was no longer a servant, a serf or a slave. There was for me no master in all the wide world -- not even in infinite space. I was free -- free to think, to express my thoughts -- free to live to my own ideal -- free to live for myself and those I loved -- free to use all my faculties, all my senses -- free to spread imagination's wings -- free to investigate, to guess and dream and hope -- free to judge and determine for myself -- free to reject all ignorant and cruel creeds, all the inspired books that savages have produced, and all the barbarous legends of the past -- free from popes and priests -- free from all the called and set apart -- free from sanctified mistakes and holy lies -- free from the fear of eternal pain -- free from the winged monsters of the night -- free from devils, ghosts and gods. For the first time I was free. There were no prohibited places in all the realms of thought -- no air, no space, where fancy could not spread her painted wings -- no chains for my limbs -- no lashes for my back -- no fires for my flesh -- no master's frown or threat – no following another's steps -- no need to bow, or cringe, or crawl, or utter lying words. I was free. I stood erect and fearlessly, joyously, faced all worlds.And then my heart was filled with gratitude, with thankfulness, and went out in love to all the heroes, the thinkers who gave their lives for the liberty of hand and brain -- for the freedom of labor and thought -- to those who fell on the fierce fields of war, to those who died in dungeons bound with chains -- to those who proudly mounted scaffold's stairs -- to those whose bones were crushed, whose flesh was scarred and torn -- to those by fire consumed -- to all the wise, the good, the brave of every land, whose thoughts and deeds have given freedom to the sons of men. And then I vowed to grasp the torch that they had held, and hold it high, that light might conquer darkness still.

If the people of Europe had known as much of astronomy and geology when the bible was introduced among them, as they do now, there never could have been one believer in the doctrine of inspiration. If the writers of the various parts of the bible had known as much about the sciences as is now known by every intelligent man, the book never could have been written. It was produced by ignorance, and has been believed and defended by its author. It has lost power in the proportion that man has gained knowledge. A few years ago, this book was appealed to in the settlement of all scientific questions; but now, even the clergy confess that in such matters, it has ceased to speak with the voice of authority. For the establishment of facts, the word of man is now considered far better than the word of God. In the world of science, Jehovah was superseded by Copernicus, Galileo, and Kepler. All that God told Moses, admitting the entire account to be true, is dust and ashes compared to the discoveries of Descartes, Laplace, and Humboldt. In matters of fact, the bible has ceased to be regarded as a standard. Science has succeeded in breaking the chains of theology. A few years ago, Science endeavored to show that it was not inconsistent with the bible. The tables have been turned, and now, Religion is endeavoring to prove that the bible is not inconsistent with Science. The standard has been changed.
