"For the first time full authoritative texts of Darwin's are made available, edited according to modern textual editorial principles and practice. Letter-writing was of crucial importance to Darwin's work, not only because his poor health isolated him from direct personal communication with his scientific colleagues but also because the nature of his investigations required communication with naturalists in many fields and in all quarters of the globe. Thus the letters are a mine of information about the work in progress of a creative genius who produced an intellectual revolution." --

In his introduction Michael Hunter draws on these studies to propound a new theory of intellectual change in this key period. Traditionally it has been seen in terms of simple polarisations - modernity against obfuscation, orthodoxy against subversion. Here, it is argued that such polarisations represent influential but idealised extremes, to which thinkers individually responded; scholars must in future have due regard to the balance between ideal types and individual complexities thus revealed.

How did Christians in early modern Western Europe express their sense of community? This book explores the various ways in which religious identities were defined, developed and defended - within both Protestant and Roman Catholic contexts, in England and on the Continent - over a period vital for the history of Christianity. As such it will be of interest not only to historians of religion but also to students of social and cultural history in general.

During 1867 Darwin intensified lines of research on human expression and sexual selection.

This volume is part of the definitive edition of letters written by and to Charles Darwin, the most celebrated naturalist of the nineteenth century. Notes and appendixes put these fascinating and wide-ranging letters in context, making the letters accessible to both scholars and general readers. Darwin depended on correspondence to collect data from all over the world, and to discuss his emerging ideas with scientific colleagues, many of whom he never met in person. The letters are published chronologically: Volume 23 includes letters from 1875, the year in which Darwin wrote and published Insectivorous plants, a botanical work that was a great success with the reading public, and started writing Cross and self fertilisation in the vegetable kingdom. The volume contains an appendix on the 1875 anti-vivisection debates, with which Darwin was closely involved, giving evidence before a Royal Commission on the subject.
