"No doubt the Mexican Indian is well suited to his environment, and his traditional habits are well suited to him. This does not mean, however, that either has any important contribution to make to the United States which would be realized by a northward mass migration of agricultural and industrial serfs. On the contrary, the Mexican immigration to the United States, which is made up overwhelmingly of the poorer Indian element, has brought nothing but disadvantages."

“The continuity of physical traits and the limitation of the effects of environment to the individual only are now so thoroughly recognized by scientists that it is at most a question of time when the social consequences which result from such crossings will be generally understood by the public at large. As soon as the true bearing and import of the facts are appreciated by lawmakers, a complete change in our political structure will inevitably occur, and our present reliance on the influences of education will be superseded by a readjustment based on racial values.”

“The Southerners understand how to treat the Negro — with firmness and with kindness — and the Negroes are liked below the Mason and Dixon line so long as they keep to their proper relation to the Whites, but in the North the blocks of Negroes in the large cities, migrating from the South, have introduced new complications, which are certain to produce trouble in the future …”

“One of its most certain results will be the partial destruction of the aristocratic classes everywhere in northern Europe … This will tend to realize the standardization of type so dear to democratic ideals. If equality cannot be obtained by lengthening and uplifting the stunted of body and of mind, it can be at least realized by the destruction of the exalted of stature and of soul.”

“There is nothing like in history in any part of the world and the result was that the aboriginal Indians were regarded as ravening wolves or worse and deprived of all sympathy, while the Whites stole their lands and killed their game. No one who knew the true nature of the Indian felt any regret that they were driven off their hunting grounds. This attitude was found wherever the Whites came in conflict with them and explains why they were scarcely regarded as human beings.”

“Africa north of the Sahara, from a zoological point of view, is now, and has been since early Tertiary times, a part of Europe. This is true both of animals and of the races of man. The Berbers of north Africa to-day are racially identical with the Spaniards and south Italians.”

“Hindu immigration has so far been nothing more than a threat. The present immigration restrictions will prevent the immigration of these people, except for travel and study. Experience in many parts of the world has shown the folly of allowing white countries to be overrun by Hindus, and Americans should sympathize with the British possessions that are trying to maintain white supremacy in their own borders in this respect.”
