It would be wryly interesting if in human history the cultivation of marijuana led generally to the invention of agriculture, and thereby to civilization.
Beer was the driving force that led nomadic mankind into village life. It was this appetite for beer-making material that led to crop cultivation, permanent settlement and agriculture.
We have seen and do see the type of evil that is within human civilization, and the Holocaust took place in European history during an advanced state of technology and form of civilization, only to become an event in that history that questioned what civilization actually means.
Cultivation is at least one of the greatest natural improvements ever made by human invention. It has given to created earth a tenfold value. But the landed monopoly that began with it has produced the greatest evil. It has dispossessed more than half the inhabitants of every nation of their natural inheritance, without providing for them, as ought to have been done, an indemnification for that loss, and has thereby created a species of poverty and wretchedness that did not exist before.
Agriculture has become essential to life; the forest, the lake, and the ocean cannot sustain the increasing family of man; population declines with a declining cultivation, and nations have ceased to be with the extinction of their agriculture.
If Mother Culture were to give an account of human history using these terms, it would go something like this: ' The Leavers were chapter one of human history -- a long and uneventful chapter. Their chapter of human history ended about ten thousand years ago with the birth of agriculture in the Near East. This event marked the beginning of chapter two, the chapter of the Takers. It's true there are still Leavers living in the world, but these are anachronisms, fossils -- people living in the past, people who just don't realize that their chapter of human history is over. '
One of the most dangerous errors is that civilization is automatically bound to increase and spread. The lesson of history is the opposite; civilization is a rarity, attained with difficulty and easily lost. The normal state of humanity is barbarism, just as the normal surface of the planet is salt water. Land looms large in our imagination and civilization in history books, only because sea and savagery are to us less interesting.
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.
The sentence is the greatest human invention of civilization.
Our political system continues to produce human rights disasters and social crises, thereby not only constricting China's own development but also limiting the progress of all of human civilization.
It is the recognition of history as a record of human experience which has inevitably resulted in the inclusion of this conquest of civilization within the framework of a complete human history.
In its broad sense, civilization means not only comfort in daily necessities but also the refining of knowledge and the cultivation of virtue so as to elevate human life to a higher plane... It refers to the attainment of both material well-being and the elevation of the human spirit, [but] since what produces man's well-being and refinement is knowledge and virtue, civilization ultimately means the progress of man's knowledge and virtue.
The individual leads in order that those who are led can develop their potential as human beings and thereby prosper.
The market is not an invention of capitalism. It has existed for centuries. It is an invention of civilization.
Marijuana is the most violence causing drug in the history of mankindMost marijuana smokers are Negroes, Hispanics, Filipinos and entertainers.
All our civilization is based on invention; before invention, men lived on fruits and nuts and pine cones and slept in caves.
Global warming would increase the rate of evaporation from the oceans. This would increase rainfall worldwide. In addition, global warming would lengthen the growing season, thereby increasing still further the bounty of both agriculture and nature.
