Robert Boyle is known to most chemists solely for his Law relating the pressure and volume of a gas, but this privileged son of the Earl of Cork was not as interested in discovering an equation as he was in determining what his experiments could tell him about his own relationship to God. Both Boyle and his contemporary, Isaac Newton, had strong spiritual inclinations, including both Christianity and alchemy. Newton was more willing to work through mathematics in search of eternal truths. For Boyle, his Christian faith permeates almost all of his writing (except for most of The Skeptical Chemist) and led to his endowment of an Oxford lectureship to preserve and defend the faith against the onslaught of "notorious infidels" such as "Jews and Mohametans", and funding for the translation of the New Testament into Irish and Algonquin. Michael Hunter is the world's expert on Boyle, and he has distilled seemingly every available historical artifact into this impressive book. Reading it makes you feel as if you have met Boyle himself.
