"Sixteen years have passed since the Chief Justice assumed his present position. These 16 years, without doubt, will be described by historians as years of greater change in America than any in our history. And that brings us to think of the mystery of government in this country, and for that matter in the world, the secret of how government can survive for free men. And we think of the terms "change" and "continuity." Change without continuity can be anarchy. Change with continuity can mean progress. And continuity without change can mean no progress."
