We the People, Constitutional Ideals and the American Experience: A Bicentennial Perspective, symposium hosted by Angelo State University, 1987.

Excerpt:

There are, as I count them, 164 countries in the world, and of these all but six (Great Britain, New Zealand, and Israel; Oman, Saudi Arabia, and Libya) have written constitutions.

Of the remaining 157 written constitutions, over half have been written since 1974, a mere thirteen years ago. In a world where constitutions come and go with almost seasonal regularity, Americans have cause to wonder why ours should have lasted so long. To what can we attribute our good fortune?
