Why I Am Agnostic from Freethought News. Lengthy, but worth every word.
(towards the end)
"Let us be true to ourselves -- true to the facts we know, and let us, above all things, preserve the veracity of our souls.
If there be gods we cannot help them, but we can assist our fellow-men. We cannot love the inconceivable, but we can love wife and child and friend.
We can be as honest as we are ignorant. If we are, when asked what is beyond the horizon of the known, we must say that we do not know."
Beautiful.
