The advance of freedom is the calling of our time; it is the calling of our country. From the Fourteen Points to the Four Freedoms, to the Speech at Westminster, America has put our power at the service of principle. We believe that liberty is the design of nature; we believe that liberty is the direction of history. We believe that human fulfillment and excellence come in the responsible exercise of liberty. And we believe that freedom -- the freedom we prize -- is not for us alone, it is the right and the capacity of all mankind.
