To live, to be able to exist, the mind must connect itself with some kind of order. It must apprehend reality as an independent whole […] and must bind itself in a stable fashion to certain features of what we call reality. It can not bind itself to the ordinary world of everyday experience, except by taking it on “faith” that reality forms an objective whole, a whole which exist independently of the mind.
The mind lives, and we live, in a relationship of “faith” with reality itself. This relationship is likewise one of confidence in a detached reality, a reality which is different and other than the mind.
We live and exist in this relationship of confidence, which is always by its nature “uncertain” and “insecure” […] The relationship of confidence […] is originally, and truly, always a relationship with reality as a natural totality: as Nature.

Other thoughts:
The ultimate obstacle to protecting Nature is the very notion of Nature we relay on.
