A Theory of Everything by Ken Wilber

Subtitled “An Integral Vision for Business, Politics, Science and Spirituality”, Wilber integrates … well, everything. His vision includes “matter, body, mind, soul and spirit as they appear in self, culture and nature… [and] embraces science, art and morals.” Much of the book is a fascinating overview of developmental psychology applied to individuals and cultures/societies, and then he describes some applications of his theory (which are illustrative, though somewhat superficial.) Interesting stuff.
