Here are a few reviews of Erazim Kohak’s book The Embers and the Stars: a philosophical inquiry into the moral sense of nature (University of Chicago Press, 1984)

"It is hard to put this profound book into a category. Despite the author's criticisms of Thoreau, it is more like Walden than any other book I have read. . . . The book makes great strides toward bringing the best insights from medieval philosophy and from contemporary environmental ethics together. Anyone interested in both of these areas must read this book."—Daniel A. Dombrowski

"Those who share Kohák's concern to understand nature as other than a mere resource or matter in motion will find his temporally oriented interpretation of nature instructive. It is here in particular that Kohák turns moments of experience to account philosophically, turning what we habitually overlook or avoid into an opportunity and basis for self-knowledge. This is an impassioned attempt to see the vital order of nature and the moral order of our humanity as one.”—Ethics

Let's plan to look at the Prolegomenon and the First chapter over the next week or two.
