We live amid falling taboos. In our crowded little hour of history we have seen how the prejudice of religion no longer can bar the way to the White House. Some of you may live to see the day when the prejudice of sex no longer places the Presidency beyond the reach of a greatly gifted American lady. Long before them, I hope you will see a woman member of the Supreme Court of the United States. In Congress and in our State Legislatures we need more women to bring their sensitive experience to the shaping of our decisions.
