On the influence of Race on intelligence, psychology, and the evolution of History

There are many human races, and what do they correspond to? Which scientific disciplines can provide the criteria for effective classification? What scientific methods can illuminate the differences among them, as well as among individuals of the same race?

What primarily differentiates the races, and what do their qualitative characteristics reveal to us about the evolution and future of human civilization? To fully understand man, it is necessary to answer these questions.

The answers are found in the book at hand and were provided at a time when pure science remained authentically humanitarian. In our days, the texts presented here are considered "forbidden," and their author deliberately forgotten. However, this is about to change.
