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.
In all its myriad manifestations, the language of anti-Semitism through the ages is a dictionary of non-sequiturs and antonyms, a thesaurus of illogic and inconsistency.
In the past, the U.S. has shown its capacity to reinvent its gifts for leadership. During the 1970s, in the aftermath of the Nixon abdication and the Ford and Carter presidencies, the whole nation peered into the abyss, was horrified by what it saw and elected Ronald Reagan as president, which began a national resurgence.
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.
Indeed it is the protean ability of Western civilization to be self-critical and self-correcting - not only in producing wealth but over the whole range of human activities - that constitutes its most decisive superiority over any of its rivals.
I was very fond of Princess Diana. She used to have me over to lunch to ask my advice. I'd give her good advice, and she'd say: 'I entirely agree. Paul, you're so right.' Then she'd go and do the opposite.
If anti-Semitism is a variety of racism, it is a most peculiar variety, with many unique characteristics. In my view as a historian, it is so peculiar that it deserves to be placed in a quite different category. I would call it an intellectual disease, a disease of the mind, extremely infectious and massively destructive.
Courage is the essential element in any great public man or woman.
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.
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.
Next to courage, willpower is the most important thing in politics.
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.
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.
When people talk about political correctness, the only element of any value is good manners.
The freedom enjoyed in Western society under the rule of law and constitutional government explains both the quality of its civilization and its wealth.
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.
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.
