This book is intended for the highly intelligent reader, who is interested in considering the difficulties, problems, and challenges of understanding and writing about the human past. It is popularly enough written, hopefully, to be a joy to read, and scholarly enough to be seriously instructive. The book has two major purposes, first, to give a reader an extensive, detailed overview of the field as it currently exists, and, second, to considerably enlarge the field itself, as it is the first book in the area to consider not only the epistemology of the field, but, in detail, its logic and semantics, its metaphysics, its axiology and its aesthetics.
