Sean Carroll explains: “Science often gives us models of the world that are more than good enough, in terms of getting answers that fit the data within the error bars, even though they might not be completely coherent or well-defined. But that’s not really what drives us to do science in the first place. We shouldn’t be happy to do ‘well enough,’ or merely fit the data – we should be striving to understand how the world really works. Our best chance of achieving that outlandish ambition is for science and philosophy to work together.”
