In this wide-ranging and stimulating book, a leading authority on the history of medicine and science presents convincing evidence that Dutch commerce, not religion, inspired the rise of science in the sixteenth and seventeenth centuries. Harold Cook scrutinizes a wealth of historical documents relating to the study of medicine and natural history in the Netherlands, Europe, Brazil, South Africa, and Asia during this era, and his conclusions are fresh and exciting. He uncovers direct links between the rise of trade and commerce in the Dutch Empire and the flourishing of scientific investigation. Cook argues that engaging in commerce changed the thinking of Dutch citizens, leading to a new emphasis on such values as objectivity, accumulation, and description. The preference for accurate information that accompanied the rise of commerce also laid the groundwork for the rise of science globally, wherever the Dutch engaged in trade. Medicine and natural history were fundamental aspects of this new science, as reflected in the development of gardens for both pleasure and botanical study, anatomical theatres, curiosity cabinets, and richly illustrated books about nature. Sweeping in scope and original in its insights, this book revises previous understandings of the history of science and ideas.
