This book is a philosophical examination of the main stages in our journey from hominid to human. It deals with the nature and origin of language, the self, self-consciousness, and the religious ideal of a return to Eden. It approaches these topics through a philosophical anthropology derived from the later writings of Wittgenstein. The result is an account of our place in nature consistent with both a hard-headed empiricism and a this-worldy but religiously significant mysticism.
