Though the general principles of statecraft have survived the rise and fall of empires, every increase in knowledge has brought about changes in the political, economic, and social structure.

The increase of territory and power of empires by force of arms has been the policy of all great powers, and it has always been possible to get the approval of their state religion.

In the last fifty years science has advanced more than in the 2,000 previous years and given mankind greater powers over the forces of nature than the ancients ascribed to their gods.

Nearly every country in the world is now becoming industrialized as rapidly as it can.

Our civilization is now in the transition stage between the age of warring empires and a new age of world unity and peace.

Empires won by conquest have always fallen either by revolt within or by defeat by a rival.

However difficult it may be to bring it about, some form of world government, with agreed international law and means of enforcing the law, is inevitable.

As we have seen, the wireless and the airplane have made the world so small and nations so dependent on each other that the only alternative to war is the United States of the World.

There can be no peace in the world so long as a large proportion of the population lack the necessities of life and believe that a change of the political and economic system will make them available. World peace must be based on world plenty.

Measured in time of transport and communication, the whole round globe is now smaller than a small European country was a hundred years ago.

As I have tried to show, science, in producing the airplane and the wireless, has created a new international political environment to which governments must adjust their foreign policies.

Some think the worst horrors of war might be avoided by an international agreement not to use atomic bombs. This is a vain hope.

In the last five or six thousand years, empires one after another have arisen, waxed powerful by wars of conquest, and fallen by internal revolution or attack from without.

We are now physically, politically, and economically one world and nations so interdependent that the absolute national sovereignty of nations is no longer possible.

When the fabric of society is so rigid that it cannot change quickly enough, adjustments are achieved by social unrest and revolutions.

When the Industrial Revolution of the nineteenth century brought a rapid increase in wealth, the demand of workers for a fair share of the wealth they were creating was conceded only after riots and strikes.

In recent times, European nations, with the use of gunpowder and other technical improvements in warfare, controlled practically the whole world. One, the British Empire, brought under one government a quarter of the earth and its inhabitants.

It is said that those whom the gods wish to destroy they first make mad. It may well be that a war neurosis stirred up by propaganda of fear and hatred is the prelude to destruction.

The history of our civilization has been one of intermittent war.

Some wars have been due to the lust of rulers for power and glory, or to revenge to wipe out the humiliation of a former defeat.

The real evil of the Russian communist state is not communism. It is the secret police and the concentration camp.

Though the general principles of statecraft have survived the rise and fall of empires, every increase in knowledge has brought about changes in the political, economic, and social structure.

If the views I have expressed be right, we can think of our civilization evolving with the growth of knowledge from small wandering tribes to large settled law.

After the First World War the economic problem was no longer one of production. It was the problem of finding markets to get the output of industry and agriculture dispersed and consumed.

Science has produced such powerful weapons that in a war between great powers there would be neither victor nor vanquished. Both would be overwhelmed in destruction.

Our civilization has evolved through the continuous adjustment of society to the stimulus of new knowledge.

During the last war when there was a market for everything that could be produced, the production capacity of Canada and the United States, which were outside the battle area, increased one hundred percent.

Education is a private matter between the person and the world of knowledge and experience, and has little to do with school or college.

Contention is inseparable from creating knowledge. It is not contention we should try to avoid, but discourses that attempt to suppress contention.

Harvard is first and foremost a university and not a consulting operation, and our job here is to teach and to research and to create knowledge on Asia in conjunction and in cooperation with scholars as well as with political, intellectual, and cultural leaders in Asia.

It was very interesting for me because DNA made music without much technical knowledge at all.

But, in the name of the experimental method and out of our poor knowledge, are we really entitled to claim that everything happens by chance, to the exclusion of all other possibilities?

The greatest gift is the passion for reading. It is cheap, it consoles, it distracts, it excites, it gives you knowledge of the world and experience of a wide kind. It is a moral illumination.

We must develop knowledge optimization initiatives to leverage our key learnings.

When a doctor does go wrong he is the first of criminals. He has nerve and he has knowledge.

There are in fact two things, science and opinion; the former begets knowledge, the later ignorance.

Knowledge is the treasure of a wise man.

We don't focus as much in schools on educational knowledge which requires thinking and application, as we do on acquiring facts.

The man of knowledge must be able not only to love his enemies but also to hate his friends.

The art and science of asking questions is the source of all knowledge.

The benefits of education and of useful knowledge, generally diffused through a community, are essential to the preservation of a free government.

I feel, sometimes, as the renaissance man must have felt in finding new riches at every point and in the certainty that unexplored areas of knowledge and experience await at every turn.

As far as knowledge goes I've come a long way.

For example, I spent a lot of time with Reagan, both before he ran for governor and when he was running for president. As a print reporter without the cameras, I was able to really test the quality of their minds and their knowledge base.

Knowledge is of two kinds. We know a subject ourselves, or we know where we can find information upon it.
