"Principe is to be congratulated on bringing [Boyle] into a new focus."--D. M. Knight, Nature "The Aspiring Adept is an audacious, enchanting, and deeply rewarding book, one that will be of equal interest to historians, chemists, and interested laypersons. It is a real treat."--A. J. Rocke, Chemistry in Britain "Lawrence Principe's book goes a long way toward recovering the complexity of Boyle's mind and work... [His] ability to reconstruct Boyle's laboratory practices, ascertain the relations between Boyle and a large community of like-minded practitioners, and retrieve, fully or partially, some of Boyle's alchemical writings is ... remarkable."--Mordechai Feingold, American Scientist "Principe has performed a great service by printing some of the choicer parts [of Boyle's unpublished works]... [He] avoids the easy temptation to interpret Boyle's alchemical operations in terms of modern chemistry."--Peter Dear, Physics World
