I flirted with believing in a generic god that intervened in human affairs for awhile, but in the end I couldn't convince myself that it was anything more than my desire for there to be a purpose behind some tragic events in my life. That's where I think deism fails the most, because deists appear to be slaves to their biases just as much as theists and can't seperate their desires from reality. To me, that is why being an agnostic atheist is the best option. It is a position that avoids certainty to keep from being tricked by my own desires.
Even if the open windows of science at first make us shiver after the cozy indoor warmth of traditional humanizing myths, in the end the fresh air brings vigor, and the great spaces have a splendor of their own - Bertrand Russell
