Reason, Observation and Experience — the Holy Trinity of Science — have taught us that happiness is the only good; that the time to be happy is now, … - Robert Green Ingersoll

It is of no earthly importance whether he changed water into wine or not. All his miracles are simply dust and darkness compared with what he actually said and actually did. We should be kind to each other whether Lazarus was raised or not. We should be just and forgiving whether Christ lived or not. All the miracles in the world are of no use to virtue, morality, or justice. Miracles belong to superstition, to ignorance, to fear and folly. Neither does it make any difference who wrote the Gospels. They are worth the truth that is in them and no more.

The greatest test of courage is to bear defeat without losing heart.

What then is, or can be called, a moral guide? The shortest possible answer is one word: Intelligence. We want the experience of mankind, the true history of the race. We want the history of intellectual development, of the growth of the ethical, of the idea of justice, of conscience, of charity, of self-denial. We want to know the paths and roads that have been traveled by the human mind. These facts in general, these histories in outline, the results reached, the conclusions formed, the principles evolved, taken together, would form the best conceivable moral guide. We cannot depend on what are called “inspired books,” or the religions of the world. These religions are based on the supernatural, and according to them we are under obligation to worship and obey some supernatural being, or beings. All these religions are inconsistent with intellectual liberty. They are the enemies of thought, of investigation, of mental honesty. They destroy the manliness of man. They promise eternal rewards for belief, for credulity, for what they call faith. This is not only absurd, but it is immoral.
