I was watching a documentary by Michio Kaku, a theoretical physicist who deals daily with equations that are very long and complex. He mentioned [heavily paraphrased from memory] that he'd love to discover the tiny, perfect equation for the universe, holding his thumb and forefinger about one inch apart. He said, "It will be beautiful in its simplicity." This is how I feel about Deism.
The "revealed" religions man has developed over millennia, do much to describe how we should live our lives, physically, morally and spiritually. But they are extremely complex and riddled with superstitions, fables, hypocracy and contradictions. Deism has none of that dogma. It's astounding in its simplicity!
