These are the questions Pietro Corsi considers in this book. He describes the debates in France, Germany, and Italy surrounding Lamarck's ideas about changing species, against the backdrop of changing political climates (the defeat of Napoleon and its aftermath). And while Continental Europe was convulsed by the 1848 revolutions, and Italy was in the throes of unification, in England perceptions of evolutionary ideas shifted from being associated with dangerous Continental radicalism and atheism, to part of reform and progress. Corsi shows how intellectual opinion shifted in England, driven by such figures as Baden Powell (grandfather of the founder of the boy scouts), and fierce debates on science and religion.
The intention of this book is not to undermine Darwin, whose accomplishments as an individual require no justification, but to put him and his work in historical context, and more pertinently in the context of social, political, and intellectual developments in Britain and the Continent. This is an extraordinarily rich and novel discussion involving the history of the development of perhaps the single greatest idea in the life sciences, written by one of the foremost scholars in the field.
