(in response to the question: what do you think of e-books and Amazon’s Kindle?) Those aren’t books. You can’t hold a computer in your hand like you can a book. A computer does not smell. There are two perfumes to a book. If a book is new, it smells great. If a book is old, it smells even better. It smells like ancient Egypt. A book has got to smell. You have to hold it in your hands and pray to it. You put it in your pocket and you walk with it. And it stays with you forever. But the computer doesn’t do that for you. I’m sorry.

You can't understand Twenty-first-Century Politics with an Eighteenth-Century Brain.
exile ... might be the largest new state created by the twentieth century and the psychology of the twenty-first century.
Twenty-first century buildings support a 21st century education - because it is difficult to learn or to teach if you are shivering.
If I quake, what matters it what I quake at? Our proper vice takes form in one or another shape, according to the sex, age, or temperament of the person, and, if we are capable of fear, will readily find terrors.
