The problem with alchemy wasn't that the alchemists had failed to turn lead into gold-no one could do that. The problem, rather, was that the alchemists had failed uninformatively. As a group, the alchemists were notably reclusive; they typically worked alone, they were secretive about their methods and their results, and they rarely accompanied claims of insight or success with anything that we'd recognize today as documentation, let alone evidence. Alchemical methods were hoarded rather than shared, passed down from master to apprentice, and when the alchemists did describe their experiments, the descriptions were both incomplete and vague. As Boyle himself complained of the alchemists' publications, "Hermetic Books have such involved Obscuritys that they may justly be compared to Riddles written in Cyphers. For after a Man has surmounted the difficulty of decyphering the Words & Terms, he finds a new & greater difficulty to discover the meaning of the seemingly plain Expression.”.
