This conclusion presents some closing thoughts on concepts discussed in the preceding chapters of this book. The book states the bracketing of oral and 'hands-on' wisdom alongside 'pure' scientific knowledge seems arbitrary. It represents the kind of society, or emblematic site of interaction, for Industrial Enlightenment. The book focuses on the role of the Birmingham savants in helping both to generate and to manage the flow of experimental scientific knowledge during the eighteenth century. It explores the links and overlaps between the popular market for science facts, discoveries and inventions, the Lunar group of natural philosophers, and the wider international web of knowledge purveyors. The book explains the relationship between religious beliefs, scientific enquiry and industrial activity in an effort to reach some broadly applicable conclusions. It offers a convincing explanation of why the ingredients of Industrial Enlightenment should be present in abundance in Birmingham and the Black Country.
