I found it!
No man believes

No man believes who, when a star falls shot,
Cries not aloud blind as a bat,
Cries not in terror when a bird is drawn
Into the quicksand feathers down,
Who does not make a wound in faith
When any light goes out, and life is death.

No man believes, who cries not, God is not,
Who feels not coldness in the heat,
In the brested summer longs not for spring,
No breasted girl, no man who,
young and green, sneers not at the old sky.
No man believes who does not wonder why.

Believe and be saved. No man believes
Who curses not what makes and saves,
No man upon this cyst of earth
Belives who does not lance his faith,
No man, no man, no man.

And this is true, no man can live
Who does not bury God in a deep grave
And then raise up the skeleton again,
No man who does not break and make,
Who in the bones finds not new faith,
Lends not flesh to ribs and neck,
Who does not break and make his final faith.
-Dylan Thomas

It's not wonderful poetry by any stretch of the imagination but I really like some of the ideas in it. Can we believe in something without thinking about it, bringing up all the arguments against it, and sometimes even not believing? Can we take faith on blind faith? I don't really think so. I think faith is too important and too personal to accept on the word of someone else. And there are definitely plenty of arguments against the existence of God. Without thinking of those arguments, do we know that God exists? This is why I've always had a great deal of respect for Thomas Aquinas. Sure, some of his arguments suck. The proofs for the existence of God? I'm not buying. But he's trying to logically answer arguments against Christian theology, rather than claiming that it's blasphemous to make these arguments. I see the Summa Theologica as a real step forward in scholarship and even religious belief.

Anyway, since the poem appears not to be available at all online, I thought I'd post it.

According to Google, I'm the #10 search result for mormon porn. A bit scary, no?
