Note 3 — INTRODUCTION.

This psychological uniformity of all races of men is independent of the question of the monogenetic or polygenetic origin of races. The psychological uniformity of different races is especially conspicuous when we observe and compare individuals of the separate races in infancy, when the distinctions produced by history, education, instruction, etc., are not yet present (see Frohschammer, Das Christenthum und die moderne Naturwissenschaft, Vienna 1868, p. 208.) When we are considering the growth of mankind in general, the stage when myths are created corresponds to the infancy of the individual.
