* There are no harsh, hard dividing lines in nature. Glaciers blend with the snow and the snow blends with the thin invisible breath of the sky. So there are no stiff, frigid, stony partition walls betwixt us and heaven. There are blendings as immeasurable and untraceable as the edges of melting clouds. Eye hath not seen, nor ear heard, etc., is applicable here, for earth is partly heaven, and heaven partly earth.

* The world, we are told, was made especially for man - a presumption not supported by all of the facts. (p. 354)
* Why should man value himself as more than a small part of the one great unit of creation? (p. 356)
