Perhaps more important than any of the causes I mentioned then as tending to race purification has been the effect of untrammeled sexual selection upon the quality of two or three successive generations.

I believe that when you have made a fuller study of our people you will find in them not only a physical, but a mental and moral improvement.

It would be strange if it were not so, for not only is one of the great laws of nature now freely working out the salvation of the race, but a profound moral sentiment has come to its support.

Individualism, which in your day was the animating idea of society, not only was fatal to any vital sentiment of brotherhood and common interest among living men, but equally to any realization of the responsibility of the living for the generation to follow.

To-day this sense of responsibility, practically unrecognized in all previous ages, has become one of the great ethical ideas of the race, reinforcing, with an intense conviction of duty, the natural impulse to seek in marriage the best and noblest of the other sex.
