Smelly's Wager (regarding the role of faith in rationalism)
I believe, with no way of proving it, that there's a universe outside myself, which was here long before I arrived and will probably go on for a very long time after I stop being aware of any of it. It is a faith in something that cannot be disproved. I'm dead certain my faith is stronger than that of any theist.
Having taken that leap, I find no further use for faith. If I believe there's really a world, that I'm not dreaming it all, then I want to be very careful what I believe about that world.
I hear, over and over, with or without invoking gods & devils, that we choose how we see the world, and it's what we have in our hearts that's the important thing. I can go along with that only so far. I believe we can chose optimism vs pessimism, that we can decide to make the most of today or to stay in bed and feel defeated.
As far as believing things about the universe, once I choose to believe it's real, and that it follows its laws whether or not we understand them, I have to have evidence. Anybody with enough sense to see past the end of their own nose will feel the same way.
So Smelly's Wager is a perversion of Pascal's, and probably not that original, but I like the sound of it. If there isn't a universe outside me, and I'm only dreaming, I have nothing to lose by pretending to interact with it, to explore and poke and doubt.
"Let us weigh the gain and the loss in wagering that the universe is. Let us estimate these two chances. If you gain, you gain all; if you lose, you lose nothing. Wager, then, without hesitation that the universe exists."
I submit that believing in god is rejecting the outside world. I submit that this is suicidally insane.
