"This correspondence continues to surprise with its remarkable detail and breadth of commentary. What elevates it to a world-class correspondence is the distinctive way in which the grand global nature of the subjects of distribution, adaptation, and geology set the context for numerous social and cultural considerations. Technical discussions of evolutionary issues spill over into considerations of the intellectual and cultural significance of biological thought, which has begun to exert a defining force on the human image itself. Many of these letters discuss the broader implications of human evolution in relation to evolution, religion, race, slavery, and the American civil war. In the Darwin correspondence, we find a way of thinking taking shape in which the natural world is inseparably and dynamically bound to the events of everyday human life." James Paradis, Quarterly Review of Biology
