Today 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 vast assemblage will agree with those sentiments. 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 1960s, a frontier of unknown opportunities and paths, a frontier of unfulfilled hopes and threats.
