“The man whose name is stuck to a starving donkey never mentioned the donkey — what he actually did was answer the skeptics, rewrite the science of motion on the road to Galileo, and prove you could be a philosopher as a job.”

“Human knowledge doesn't need to be doubt-proof to be real: science is certain on the assumption that nature runs its usual course — and that kind of certainty is enough to build on.”
