If the assertion that there is a god is nonsensical, then the atheist's assertion that there is no god is equally nonsensical, since it is only a significant proposition that can be significantly contradicted.
The great Creator to revere
Must sure become the creature;
But still the preaching cant forbear,
And ev'n the rigid feature:
Yet ne'er with wits profane to range
Be complaisance extended;An atheist laugh's a poor exchange
For deity offended.
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.
I do not believe in God. It seems to me that theists of all kinds have very largely failed to make their concept of a deity intelligible; and to the extent that they have made it intelligible, they have given us no reason to think that anything answers to it.
The religious geniuses of all ages have been distinguished by this kind of religious feeling, which knows no dogma and no God conceived in man's image; so that there can be no church whose central teachings are based on it. Hence it is precisely among the heretics of every age that we find men who were filled with this highest kind of religious feeling and were in many cases regarded by their contemporaries as atheists, sometimes also as saints. Looked at in this light, men like Democritus, Francis of Assisi, and Spinoza are closely akin to one another.
What I see in Nature is a magnificent structure that we can comprehend only very imperfectly, and that must fill a thinking person with a feeling of humility. This is a genuinely religious feeling that has nothing to do with mysticism.
