Far too many of the present inhabitants of this earth who are _not_ wanted because of their inferiority, were children who came to reluctant, perhaps horror-stricken, mothers. To this fact, I trace very largely the mental and physical aberrations which are to-day so prevalent; to this also I trace the bitterness, the unrest, the spirit of strife and malignity which seem to be without precedent in the world at present [see also _The Control of Parenthood_, final section, and, for the remedy, my book, _Wise Parenthood_, both published by Putnam]. The warped and destructive impulse of revolution which is sweeping over so many people at present must have its roots in some deep wrong. Revolution is not a natural activity for human beings. Though the revolutionary impulse has swept through sections of humanity many times in its history, it is essentially unnatural, an indication of warping and poisoning, and a cause of further and perhaps irreparable damage. Happy people do not indulge in revolution. Happy people with a deep sense of underlying contentment and satisfaction in life may yet strive ardently to improve and beautify everything round them. They strive in the same direction as the main current of life--that is the growth and unfolding of ever increasing beauty. The revolutionaries--bitter, soured and profoundly unhappy--pit their strength against the normal stream of life and destroy, break down and rob. Too long humanity has had to endure such outbreaks owing to its general blindness and lack of understanding of their causes. Until the scientific spirit of profound inquiry into fundamental causes becomes general even in a small section of the community, superficial and apparently obvious explanations are accepted to account for results which really arise from profound and secret springs. The “divine discontent” which has impelled humanity forward along the path of constructive progress is a very different thing from the bitter discontent which leads to revolutionary and destructive outbursts. The village blacksmith of the well-known song, using his healthy muscles on hard, useful work which gives him a deep physical satisfaction, may feel the former and help forward the stream of progress in his village. The aim of reformers to-day should be to provide for every one neither ease nor comfort, nor high wages nor short hours, but the deeper necessities of a full and contented life, bodies able to respond with satisfaction to the strain of hard work performed under conditions which satisfy the mind in the most fundamental way of all--the deep, sub-conscious satisfaction which is given by the sweet smell of earth, by fresh air and sunshine, and green things around one.
