Take from the church the miraculous, the supernatural, the incomprehensible, the unreasonable, the impossible, the unknowable, the absurd, and nothing but a vacuum remains.

No one infers a god from the simple, from the known, from what is understood, but from the complex, from the unknown, and incomprehensible. Our ignorance is God; what we know is science.

The doctrine that future happiness depends upon belief is monstrous. It is the infamy of infamies. The notion that faith in Christ is to be rewarded by an eternity of bliss, while a dependence upon reason, observation and experience merits everlasting pain, is too absurd for refutation, and can be relieved only by that unhappy mixture of insanity and ignorance, called 'faith.

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, and the way to be happy is to make others so. This is enough for us. In this belief we are content to live and die. If by any possibility the existence of a power superior to, and independent of, nature shall be demonstrated, there will then be time enough to kneel. Until then, let us stand erect.

I have yet to understand the ritual of sacrifice in monotheism; to a supposed Creator who has supposedly given us what we will be eventually sacrificing.
If I take a small mirror and reflect sunlight back to the sun, am I sacrificing to the sun?
