More late 18th C, and another look at the science of Joseph Priestley's times... when science was in a growth spurt, and modern chemistry was being born. Through Beddoes story, we are immersed in the life of a late 18th C man of science at a time of high ideals. Freethinkers wanted fair and free society, so abolition of slavery was a rising concern. The ideals of the French Revolution inspired these men to hope for justice. And Beddoes' own commitment to the betterment of the human condition allowed the author to illuminate the relationship between the state and the individual. It was a revelation to me that the English would actually fear French invasion, and for so many years it was its own era of "Homeland Security" with laws about sedition being regularly enacted.
I was horrified though, at the immediacy of the men's involvement with their pneumatic sciences. Can you imagine inhaling various gases unsure of their impact, short or long term?! Humphry Davy, who went on to the Chair of the Royal Society, was a self educated young man who arrived at Beddoes Pneumatic Institute in the Bristol area and did just that! Isolating various 'airs' and then inhaling them and noting their effects.
This is a wonderful telling of how single minded earnest inquiry, no matter the limitations of understanding, is the way to develop knowledge.
