That is certainly the point: when the human species was born, on the African savanna, life was pretty good; we could live in harmony with the rest of nature, and that's what I've been calling Eden. The only technologies that humans devised for some 2 million years were fire and the hand ax. That's all. Eden didn't need anything more

Everyone is shy - it is the inborn modesty that makes us able to live in harmony with other creatures and our fellows. Achievement comes not by denying shyness but, occasionally, by setting it aside and letting pride and perspiration come first.

Economic and social misery increases in direct proportion to the size and power of the central government of a nation or state.

I mean that sense of nature that Aldo Leopold had in mind when he said, "A thing is right when it tends to preserve the integrity, stability, and beauty of the biotic community, wrong when it tends otherwise.
