However much truth there may be in the flippant comment that the Lord Chancellor Francis Bacon wrote about science like—a Lord Chancellor, we have the express testimony of the founders of the Royal Society that their business was to consider things pertaining to what had been called his "New Philosophy." The student of plants and animals was no longer primarily concerned, as he had been in the 15th century, with the opinions of Aristotle, Theophrastus, Dioscorides, and other ancient writers, as to the identity, structure and physiology of the organisms in question : he was not now to give his chief attention to the medicinal uses of the plants he studied, as had, almost without exception
