What do natural behaviour, natural landscapes, natural yoghurt and natural theology have in common? This wide-ranging study of the origins and use of the concept of nature aims to throw light on many of today's contoversial issues - from sexuality and designer babies to GM foods. The Concept of Nature examines practical questions such as whether there are laws of nature which can lead us to describe some human behaviours as natural and other unnatural, and seeks to guide Christian thinking by identifying God as the source of both nature's givenness and of its immense potential for change.
