More than a book about Darwin and the theory of evolution, this is a case study in the publication, dissemination, and acceptance of a scientific theory in the nineteenth century. In his introduction, David Hull explains the philosopy of science that prevailed in the 1850s, focusing on what was considered proper scientific evidence as well as what constituted acceptable proof or support of a theory. He then presents fifteen original reviews of the Origin along with comments on each review from Darwin\'s correspondence, and he follows each review with a note placing it in is historical and conceptual context.
