If we were to select the most intelligent, imaginative, energetic, and emotionally stable third of mankind, all races would be present.

There is no fundamental difference in the ways of thinking of primitive and civilized man. A close connection between race and personality has never been established.

It is clear, from these considerations, that the three methods of classifying mankind-that according to physical characters, according to language, and according to culture-all reflect the historical development of races from different standpoints; and that the results of the three classifications are not comparable, because the historical facts do not affect the three classes of phenomena equally. A consideration of all these classes of facts is needed when we endeavour to reconstruct the early history of the races of mankind.

It is our task to inquire into the causes that have brought about the observed differentiation, and to investigate the sequence of events that have led to the establishment of the multifarious forms of human life
