Civilization as it is known today could not have evolved, nor can it survive, without an adequate food supply.

Civilization must stand up and combat the current collapse of governance, the rise of violence, and the spread of chaos and fear in many parts of the world.

Our society must make it right and possible for old people not to fear the young or be deserted by them, for the test of a civilization is the way that it cares for its helpless members.

We - what we need is a dialogue among civilizations. And we need multiculturalism, respect for diversity, tolerance, respect for diverse faiths.

I had faith in Israel before it was established, I have in it now. I believe it has a glorious future before it - not just another sovereign nation, but as an embodiment of the great ideals of our civilization.

Civilization is a failure. We need to think what we can do together in love and peace.

If you look at great human civilizations, from the Roman Empire to the Soviet Union, you will see that most do not fail simply due to external threats but because of internal weakness, corruption, or a failure to manifest the values and ideals they espouse.

The American economic, political, and social organization has given to its citizens the benefits of material prosperity, political liberty, and a wholesome natural equality; and this achievement is a gain, not only to Americans, but to the world and to civilization.

Civilization is built on a number of ultimate principles... respect for human life, the punishment of crimes against property and persons, the equality of all good citizens before the law... or, in a word justice.

We will never have true civilization until we have learned to recognize the rights of others.

Civilization has given us enormous successes: going to the moon, technology. But then this is the civilisation that took us to debt, environmental crisis, every single crisis. We need a civilization where we say goodbye to these things.

Human civilization as we know it is like the Titanic headed for the iceberg, whether the iceberg be nuclear, environmental or terrorism-related.

To defend a country you need an army, but to defend a civilization you need education.

The right to a quality education is, I believe, the perfect path to bridge the gap between different cultures and to reconcile various civilizations. Without such a right, the values of liberty, justice and equality will have no meaning. Ignorance is by far the biggest danger and threat to humankind.

Education is the transmission of civilization.

Personally, my interests are ancient history and ancient civilizations. In my own life, I'd like to go to places like Easter Island.

A nation or civilization that continues to produce soft-minded men purchases its own spiritual death on the installment plan.

Well, we can't afford blindness anymore. There are tens of thousands of thugs who loathe liberty and love death, and want to annihilate Western civilization.

If there hadn't been women we'd still be squatting in a cave eating raw meat, because we made civilization in order to impress our girlfriends.

Amid apocalyptic dystopia, 'Fahrenheit 451''s protagonist retains sparks of curiosity, creativity, and courage, and these human characteristics are the seeds of hope that can arise, phoenix-like, from civilization's ashes.

Before language, cavemen simply grunted, and then they used the club. Communication changed that. It's the mechanism that created civilization and prevents its own destruction.

Civilization grew in the beginning from the minute that we had communication - particularly communication by sea that enabled people to get inspiration and ideas from each other and to exchange basic raw materials.

Civilization exists by geological consent, subject to change without notice.

We've gotta become the Martians. I'm a Martian - I tell you to become Martians. And we've gotta go to Mars and civilize Mars and build a whole civilization on Mars and then move out, 300 years from now into the universe. And when we do that, we have a chance of living forever.
