"One could paraphrase Mark Twain in saying that everybody talks about the new worldview of the sciences but nobody quite knows what it is. Certainly, not many people do anything about exploring it and making it explicit. Yet understanding this worldview is important. If you want to change the world, or at least make sure that it doesn't head blindly to its own destruction, you have to understand the nature of this world. And if you want to understand it, you have to interpret what you experience and know of it through some intelligible hypothesis."
