“The phrase “Sense of the Earth’ should be understood to mean the passionate concern for our common destiny which draws the thinking part of life ever further onward. In principle there is no feeling that has a firmer foundation in nature, or greater power.

But in fact, there is also no feeling which awakens so belatedly, since it can become explicit only when our consciousness has expanded beyond the broadening, but still far too restricted, circles of family, country and race, and has finally discovered the only truly natural and real human Unity is the Spirit of Earth.”
