The current ecological crisis is a matter of urgent global concern, with solutions being sought on many fronts. In this book, Seyyed Hossein Nasr argues that the devastation of our world has been exacerbated, if not actually caused, by the reductionist view of nature that has been advanced by modern secular science. What is needed, he believes, is the recovery of the truth to which the great enduring religions attest, namely, that nature is sacred.
