practical scientific insights, not theoretical ones. They do not know for a fact what makes up herbs, monsters, or the plague, but they
do know what role each can and should play in human society. Modern readers will know that understanding the inner nature of medicines, animals, and diseases can help sciences use and fight them. But, in the 17th century, Cavendish did not seem to think that this was as important a goal as merely identifying problems and solutions.
