Is there any possibility of giving international air travel, which we all need and use and hate, a touch of glamour, or even of reliable, soulless efficiency? I suspect future historians will puzzle over our failure. But by then, of course, we shall be in the age of mass space travel, with its fresh and unimaginable crop of horrors.

It would be wrong to say I enjoy having rows, because that would be un-Christian. If people attack me, then I respond, or if they do very wicked things. Then they must be brought to book.

Like many physical diseases, anti-Semitism is highly infectious, and can become endemic in certain localities and societies. Though a disease of the mind, it is by no means confined to weak, feeble, or commonplace intellects; as history sadly records, its carriers have included men and women of otherwise powerful and subtle thoughts.

Margaret Thatcher had more impact on the world than any woman ruler since Catherine the Great of Russia. Not only did she turn around - decisively - the British economy in the 1980s, she also saw her methods copied in more than 50 countries.

Marxism, Freudianism, global warming. These are proof - of which history offers so many examples - that people can be suckers on a grand scale. To their fanatical followers they are a substitute for religion. Global warming, in particular, is a creed, a faith, a dogma that has little to do with science.

Mr. Obama would be a disheartening president even during a super boom, with his grim demeanor and empty rhetoric, as well as his obvious hatred of business bravado.

One of the categories of people I don't like much are intellectuals. People say, 'Oh, you're an intellectual,' and I say, 'No!' What is an intellectual? An intellectual is somebody who thinks ideas are more important than people.

One of the marvelous things about Churchill is that whatever he was doing, whether fighting or arguing or despairing or bouncing about full of energy, jokes are never far away.

The freedom enjoyed in Western society under the rule of law and constitutional government explains both the quality of its civilization and its wealth.

The idea that human beings have changed and are changing the basic climate system of the Earth through their industrial activities and burning of fossil fuels - the essence of the Greens' theory of global warming - has about as much basis in science as Marxism and Freudianism.

The image of the scientist who puts the pursuit of truth before anything else has been shattered and replaced by a man on the make or a quasi-religious enthusiast who wants to prove his case at any cost. Science is becoming the tool of campaigning warfare, in which truth is the first casualty.

The most intimidating world leader was Lyndon Johnson, who became U.S. President when John Kennedy was assassinated. He exulted in this power and liked to inspire fear.

The only thing to be said for air travel is speed. It makes possible travel on a scale unimaginable before our present age. Between the ages of 20 and four-score I visited every country in Europe, all save two in Latin America, ditto in Africa, and most of Asia, not counting eight trips to Australia and 60 to the United States - all by air.

The planet Earth, though not threatened with destruction by man-made global warming, is by no means indestructible. There are many unpredictable events within our solar system, and still more outside it, that could make Earth uninhabitable by humans.

The United States is a concept that works very well, even in bad times. But that's no reason to think its structure can be superimposed with success on any other part of the world, particularly when times are terrible.

The whole world depends on America ultimately, particularly Britain. And also, I love America - a marvelous country. But in a sense I don't worry about America because I think America has such huge strengths - particularly its freedom of thought and expression - that it's going to survive as a top nation for the foreseeable future.

Those who buy in to global warming wish to drastically curb human economic and industrial activities, regardless of the consequences for people, especially the poor.

What strikes the historian surveying anti-Semitism worldwide over more than two millennia is its fundamental irrationality. It seems to make no sense, any more than malaria or meningitis makes sense.

Where the quest for knowledge is relatively, and now almost absolutely, unrestrained, the public benefit will be great, especially where the certainty of the law ensures that knowledge is rewarded. This is exactly the combination that is the foundation of wealth-creation.

A capitalist economy hums when leading businessmen are bubbling with animal spirits and are prepared to sink their money into risky ventures.
