I'm convinced that the catastrophes of the next two decades will be so vast as to bring about a world where life, if it survives, will be far simpler - and the technologies, too. Then we will have come full circle to something like life on the savanna.

That is the onslaught. It has been going on a long time, I argue, but in the 20th century humans have certainly perfected it, extending domination to every single corner of the earth and our Homo sapiens population to more than 6 billion - until no place is untouched by despoliation.

My analysis, especially of the computer revolution, always comes back to capitalism. It's that economic system that has led to Western civilization's willingness to enslave ourselves to machines - because some people benefit enormously from it, while the costs are borne by other people and the planet.

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.

The virtue of small government is that the mistakes are small as well...If you want to leave a nation you think is corrupt, inefficient, militaristic, oppressive, repressive, but you don't want to move to Canada or France, what do you do? Well, the way is through secession, where you could stay home and be where you want to be.

It's from love and knowledge of nature that any sensible understanding must come. Technology is essentially antagonistic to nature - that in fact is why it's created, to do something to or with nature that wasn't there before, that wasn't natural.

When I speak of knowledge of nature, I do not mean industrial science, which argues that nature is inert and can be understood only to enable humans to manipulate it. 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.
