A collection of original essays offering a comprehensive history of the emergence of scientific naturalism. Beginning with the naturalists of ancient Greece, and proceeding through the middle ages, the scientific revolution, and into the nineteenth century, the contributors examine past ideas about 'nature' and 'the supernatural'. Ranging over different scientific disciplines and historical periods, they show how past thinkers often relied upon theological ideas and presuppositions in their systematic investigations of the world. In addition to providing material that contributes to a history of 'nature' and naturalism, this collection challenges a number of widely held misconceptions about the history of scientific naturalism.
