Here - a perspective by Russell A. Fox on one of the great environmentalists of our time. Berry is indispensable; I used one of his shorter books - Life is A Miracle once in a course. The book is essentially a response to Edward Wilson's Consilience, an empiricist attempt to claim that ethics is a branch of human biology. The students (at least those who did the reading) really caught on to the radically different way of being an environmentalist that Berry promotes.
