Early Modern Mindset

From Aldous Huxley's The Devils of Loudun, emphasis my own:

For the age of Descartes and Newton was also the age of Fludd and Sir Kenelm Digby; the age of logarithms and analytical geometry was no less the age of the weapon salve, the Sympathetic Powder, the theory of Signatures. Robert Boyle, who wrote The Sceptical Chemist and was one of the founders of the Royal Society, left a volume of recipes for home remedies. Culled from an oak at the full moon, mistletoe berries dried, powdered and mixed with black cherry water, will cure epilepsy. For apoplectic fits, one must take mastic (the resin exuded by lentisk bushes on the island of Chios), extract the essential oil by distillation in a copper alembic and blow two or three drops, through a quill, into one of the patient's nostrils, "and after a while into the other." The scientific spirit was already vigorously alive. But no less vigorously alive was the spirit of the medicine man and the witch.
