Leadership in Freedom depends on fidelity and persistence in those shaping beliefs—democracy, freedom, justice —which men follow not from the enslavement of their bodies but from the compulsion of their hearts. We must cope with real dangers, overcome real obstacles, meet real needs; but always in a way which preserves our own allegiance to the fundamental principles and promises of the American Constitution. Otherwise we will preserve the shadow of progress and security at the expense of the substance of freedom here in America and all around the world.
