Agriculture is not crop production as popular belief holds - it's the production of food and fiber from the world's land and waters. Without agriculture it is not possible to have a city, stock market, banks, university, church or army. Agriculture is the foundation of civilization and any stable economy.
A civilization that only looks inward will stagnate. We have to keep looking outward; we have to keep finding new avenues for human endeavor and human expression.
If civilization is to survive, we must cultivate the science of human relationships - the ability of all peoples, of all kinds, to live together, in the same world at peace.
The only people who steal are thieves, and that's a very small percentage of civilization. Most people want to have some way to make the economic transaction valid. They want to return the favor, if you will... return the benefit and reciprocate.
Rules governing defecation, hygiene, and pollution exist in every culture at every period in history. It may in fact be the foundation of civilization: What is toilet training if not the first attempt to turn a child into an acceptable member of society?
The greatest advances of civilization, whether in architecture or painting, in science and literature, in industry or agriculture, have never come from centralized government.
We're a depraved civilization. All this technology, all the computer games and the iPhones... nobody will sit for art anymore. What a dismaying state of humanity.
When tillage begins, other arts follow. The farmers, therefore, are the founders of human civilization.
If the battle for civilization comes down to the wimps versus the barbarians, the barbarians are going to win.
Justice has nothing to do with victor nations and vanquished nations, but must be a moral standard that all the world's peoples can agree to. To seek this and to achieve it - that is true civilization.
