Tricks of the Trade Quotes

“That’s a general point. Nothing stays the same. Nothing is the same as anything else. We do not operate in the world of physicists, where we can take a sample of a pure substance off the shelf and know that it is, near enough as makes no difference, the same substance any other scientist in the world will be handling under that name. None of our “substances” are pure anything. They are all historically contingent, geographically influenced combinations of a variety of processes, no two of the combinations alike. So we can never ignore a topic just because someone has already studied it.”
