There are two things which make it impossible to believe that this world is the successful work of an all-wise, all-good, and at the same time, all-powerful being; firstly, the misery which abounds in it everywhere; and secondly, the obvious imperfection of its highest product, man, who is a burlesque of what he should be.
Human vanity is so constituted that it stiffens before difficulties. The more an object conceals itself from our eyes, the greater the effort we make to seize it, because it pricks our pride, it excites our curiosity and it appears interesting. In fighting for his God everyone, in fact, fights only for the interest of his own vanity, which, of all the passions produced bye the mal-organization of society, is the quickest to take offense, and the most capable of committing the greatest follies.
An atheist is someone who is certain that God does not exist, someone who has compelling evidence against the existence of God. I know of no such compelling evidence. Because God can be relegated to remote times and places and to ultimate causes, we would have to know a great deal more about the universe than we do now to be sure that no such God exists. To be certain of the existence of God and to be certain of the nonexistence of God seem to me to be the confident extremes in a subject so riddled with doubt and uncertainty as to inspire very little confidence indeed.
I think it's perfectly consistent to say that I want my government to be operating for all faiths and all peoples, including atheists and agnostics, while also insisting that there are values tha tinform my politics that are appropriate to talk about.
The atheists are for the most part imprudent and misguided scholars who reason badly who, not being able to understand the Creation, the origin of evil, and other difficulties, have recourse to the hypothesis the eternity of things and of inevitability.
The essence of religious feeling does not come under any sort of reasoning or atheism, and has nothing to do with any crimes or misdemeanors. There is something else here, and there will always be something else - something that the atheists will for ever slur over; they will always be talking of something else.
We should foster a culture in which people's private religious beliefs, including atheists and agnostics, are respected. And that's the kind of culture that I think allows all of us, then, to believe what we want. That's freedom of conscience. That's what our Constitution guarantees.
