My firm conviction is that if wide-spread Eugenic reforms are not adopted during the next hundred years or so, our Western Civilization is inevitably destined to such a slow and gradual decay as that which has been experienced in the past by every great ancient civilization. The size and the importance of the United States throws on you a special responsibility in your endeavours to safeguard the future of our race. Those who are attending your Congress will be aiding in this endeavour, and though you will gain no thanks from your own generation, posterity will, I believe, learn to realize the great dept it owes to all the workers in this field.
