The existence of a general law does not exclude exceptions. The fact that in the case of human beings we have to take into consideration a powerful factor that does not come into play in the domain of zoölogy and botany--the immortal soul--makes impossible the drawing of exact deductions from precedents therein established. This determining touch of the divine, which is no result of biological processes, but stands outside the limitations of heredity and environment and education, may manifest itself quite as well in one class as in another, for "God is no respecter of persons." As has been said before, there is no difference in degree as between immortal souls. The point is, however, that each is linked to a specific congeries of tendencies, limitations, effective or defective agencies, that are what they have been made by the parents of the race. These may be such as enable the soul to triumph in its earthly experience and in its bodily housing; they may be such as will bring about failure and defeat. It is not that the soul builds itself "more stately mansions"; it is that these are provided for it by the physical processes of life, and it is almost the first duty of man to see that they are well built. Again, the soul is single and personal; as it is not a plexus of inherited tendencies, so it is not heritable, and a great soul showing suddenly in the dusk of a dull race contributes nothing of its essential quality to the issue of the body it has made its house. The stews of a mill town may suddenly be illuminated by the radiance of a divine soul, to the amazement of profligate parents and the confusion of eugenists; but unless the unsolvable mystery of life has determined on a new species, and so by a sudden influx of the _élan vital_ cuts off the line of physical succession and establishes one that is wholly new, then the brightness dies away with the passing of the splendid soul, and the established tendencies resume their sway. The bearing of this theory on the actions of society is immediate. Through the complete disregard of race-values that has obtained during the last two or three centuries, and the emergence and complete supremacy in all categories of life of human groups of low potential, civilization has been brought down to a level where it is threatened with disaster. If recovery is to be effected and a second era of "dark ages" avoided, there must be an entirely new evaluation of things, a new estimate of the principles and methods that obtained under Modernism, and a fearless adventure into fields that may prove not to be so unfamiliar as might at first appear.
