One of the most exciting intellectual moments of my career was my 1948 discovery of Knut Wicksell's unknown and untranslated dissertation, 'Finanztheoretische Untersuchungen,' buried in the dusty stacks of Chicago's old Harper Library.

In 1987, the United States celebrates the bicentennial anniversary of the constitutional convention that provided the basic rules for the American political order. This convention was one of the very few historical examples in which political rules were deliberately chosen.

I'm a technology person, but I'm not a science person.

Explorations into chemistry were done in our basement, sometimes with friends, and my parents must have had quite a bit of confidence in my abilities when they allowed me to experiment with explosive mixtures.

The march of science and technology does not imply growing intellectual complexity in the lives of most people. It often means the opposite.

When the state was going to tell you what your future would be, science fiction was irrelevant.
