Americans ought to be the best-traveled, most cosmopolitan people on earth, not only because experience of the world is desirable in its own right, but because as a people acquires a great concentration of power, worldliness becomes a moral imperative.

Ireland is not at all a simple place, and in many ways it is spare and sad. It has no wealth, no power, no stability, no influence, no fashion, no size. Its only real arts are song and drama and poem. But Limerick alone has two thousand ruined castles and surely that many practicing poets.

The Federal Building's large Ceremonial Courtroom, reserved for show trials, is veneered in executive teak. Bench, counsel tables, jury boxes, entrances, and exits -- all are as formally arranged as an Elizabethan stage.
