Some would say that those struggles are all over — that all the horizons have been explored — that all the battles have been won — that there is no longer an American frontier.
But I trust that no one in this assemblage would agree with that sentiment. For the problems are not all solved and the battles are not all won. And we stand today on the edge of a new frontier — the frontier of the Nineteen Sixties — the frontier of unknown opportunities and perils — the frontier of unfulfilled hopes and threats.
