The love of nature is a passion for those in whom it once lodges. It can never be quenched. It cannot change. It is a furious, burning, physical greed, as well as a state of mystical exaltation. It will have its own.
Anything we destroy in ourselves we destroy in others. Our falls lower others and throw them down; we owe it to our fellows to keep upright, in order that they too may keep their feet.
