ABSTRACT
The date of this mutation can be fixed with fair accuracy as being somewhere in the fifth millen nium before Christ.1 Two thousand years later at most, the high Cultures are beginning in Egypt and Mesopotamia. Truly the tempo of history is work ing up tragically. Hitherto thousands of years have scarcely mattered at all, but now every century becomes important. With tearing leaps, the rolling stone is approaching the abyss.
