What is Science? • Before the nineteenth century, what we call science was referred to as natural philosophy, and was to varying degrees entangled with moral philosophy, theology, numerology, and magic. • By the Renaissance, science was often to also mean “art” in describing a particular body of knowledge. These usages continued until the early nineteenth century. But also, by the end of the sixteenth century, “science,” requiring theoretical knowledge, was often differentiated from “art,” a skill that required only practice.

11. What is Science? • By 1800, though science mostly meant just the theoretical and methodical study of nature, it had for a growing number become associated with specific ways of thought and methods that we would now consider scientific. • In the mid-nineteenth century, the word “scientist” was first used to replace the earlier term “natural philosopher;” and “science” referred primarily to the, by then, well differentiated fields of physics, chemistry, and biology.
