The Apothecary As Man of Science
Iv THE APOTHECARY AS MAN OF SCIENCE INTRODUCTION The development and use of rational scientific methods was well established by the mid-seventeenth century. The collection of data and the systematic arrangement of ideas, the application of mathematics and sound reasoning, and, above all, the experi- mental testing of hypotheses, advocated by men of the calibre of Johan Kepler (1571-1630), Galileo Galilei (1564-1642), Francis Bacon (1561-1626), and Rene Descartes (1596-1650) were, by the time of the Commonwealth, accepted roads to the advancement of knowledge. A new intellectual outlook had evolved, as noted by John Aubrey (1626-97) in 1671, "Till about the year 1649 'twas held a strange presumption for a man to attempt an innovation of learning". The English apothecary was, of course, much influenced by these changes. He developed methods of inquiry and investigation, he experimented, he joined societies, he wrote to like-minded contemporaries, he published his findings, and, above all, he had the good fortune to be caught in the toils of collectors' mania, be it "curiosities" or new information. The apothecary had a particular interest in those fields that most closely impinged upon his own profession - botany, chemistry, and medicine. Although considerable advances in the description and classification of plants and animals had been made by 1760, no great theoretical principles or "laws" of biology had been developed. It should be noted, though, that the generation of scientists arriv- ing on the scene after 1760 was able to study an immensely richer collection of natural history specimens from distant lands, which helped towards developing new interpretations of Nature based on sounder doctrines.
