During the past 50 years the Neo-Darwinian synthesis of evolutionary theory with genetics has provided a new model of what nature is, with much to say about human behaviour as a result of developments in palaeoanthropology and sociobiology. This text explores the possible consequences for philosophy, reliogion and the humanities in general. The essays are written by someone trained in the humanities to understand the new nature and the intellectual restructuring it may require we make. Essays on nature are interspersed with others on poets, including R.S. Thomas, A.R. Ammons and Harry Martinson who have responded in this century to the new thinking about nature.
