Quotes

  • The power to declare war involves the power to do almost anything else in foreign affairs, because war is the ultimate sanction for all the other activities of statesmanship. It must be held in reserve, not only for defense against an actual attack, but to prevent an attack, which can be done most effectively by the threat of its use. Invalidation of this power, or diminution of its scope, cripples the foreign policy of the United States and makes it difficult to achieve our objectives in peace as well as in war. - J. William Fulbright
  • The notion that the church, the press, and the universities should serve the state is essentially a Communist notion. In a free society these institutions must be wholly free – which is to say that their function is to serve as checks upon the state. - Alan Barth
  • There is nothing so powerful as truth – and often nothing so strange. - Daniel Webster
