The last question was asked for the first time, half in jest, on May 21, 2061, at a time when humanity first stepped into the light. The question came about as a result of a five dollar bet over highballs, and it happened this way…

If my doctor told me I had only six minutes to live, I wouldn't brood. I'd type a little faster.

The fall of Empire, gentlemen, is a massive thing, however, and not easily fought. It is dictated by a rising bureaucracy, a receding initiative, a freezing of caste, a damming of curiosity - a hundred other factors. It has been going on, as I have said, for centuries, and it is too majestic and massive a movement to stop.

I fear my ignorance.

I have always dealt with economic forces, rather than philosophic forces, but you can't split history into neat little non-overlapping divisions. For instance, religions tend to accumulate wealth when successful and that eventually tends to distort the economic development of a society.

It takes more than capital to swing business. You've got to have the A. I. D. degree to get by - Advertising, Initiative, and Dynamics.

Knowledge is indivisible. When people grow wise in one direction, they are sure to make it easier for themselves to grow wise in other directions as well. On the other hand, when they split up knowledge, concentrate on their own field, and scorn and ignore other fields, they grow less wise - even in their own field.
