Although the idea that all human beings are descended from Adam is a long standing conviction in the West, another version of this narrative exists - humans inhabited the Earth before, or alongside, Adam, and their descendants still occupy the planet. This book traces the history of and debates surrounding the idea of non-Adamic humanity.

The Dictionary of Early American Philosophers, which contains over 400 entries by nearly 300 authors, provides an account of philosophical thought in the United States and Canada between 1600 and 1860. The label of "philosopher" has been broadly applied in this Dictionary to intellectuals who have made philosophical contributions regardless of academic career or professional title. Most figures were not academic philosophers, as few such positions existed then, but they did work on philosophical issues and explored philosophical questions involved in such fields as pedagogy, rhetoric, the arts, history, politics, economics, sociology, psychology, medicine, anthropology, religion, metaphysics, and the natural sciences. Each entry begins with biographical and career information, and continues with a discussion of the subject's writings, teaching, and thought. A cross-referencing system refers the reader to other entries. The concluding bibliography lists significant publications by the subject, posthumous editions and collected works, and further reading about the subject.

The nineteenth century witnessed a dramatic shift in the display and dissemination of natural knowledge across Britain and America, from private collections of miscellaneous artifacts and objects to public exhibitions and state-sponsored museums. The science museum as we know it—an institution of expert knowledge built to inform a lay public—was still very much in formation during this dynamic period. Science Museums in Transition provides a nuanced, comparative study of the diverse places and spaces in which science was displayed at a time when science and spectacle were still deeply intertwined; when leading naturalists, curators, and popular showmen were debating both how to display their knowledge and how and whether they should profit from scientific work; and when ideals of nationalism, class politics, and democracy were permeating the museum's walls. Contributors examine a constellation of people, spaces, display practices, experiences, and politics that worked not only to define the museum, but to shape public science and scientific knowledge. Taken together, the chapters in this volume span the Atlantic, exploring private and public museums, short and long-term exhibitions, and museums built for entertainment, education, and research, and in turn raise a host of important questions, about expertise, and about who speaks for nature and for history.
