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.
Indeed, the study of universities and the great men and women who have attended them leads me to think that the best of these schools are characterized not so much by what they teach and how they teach it but by the extent they provide opportunities and encouragement for students to teach themselves.
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.
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.
