A quote from Rober Ingersoll

[Science] found the world at the mercy of disease and famine; men trying to read their fates in the stars, and to tell their fortunes by signs and wonders; generals thinking to conquer their enemies by making the sign of the cross, or by telling a rosary. It found all history full of petty and ridiculous falsehood, and the Almighty was supposed to spend most of his time turning sticks into snakes, drowning boys for swimming on Sunday, and killing little children for the purpose of converting their parents. It found the earth filled with slaves and tyrants, the people in all countries downtrodden, half naked, half starved, without hope, and without reason in the world. Such was the condition of man when the morning of science dawned upon his brain, and before he had heard the sublime declaration that the universe is governed by law. For the change that has taken place we are indebted solely to science--the only lever capable of raising mankind. Abject faith is barbarism; reason is civilization. To obey is slavish; to act from a sense of obligation perceived by the reason, is noble. Ignorance worships mystery; Reason explains it: the one grovels, the other soars.
