Realising all the factors--the innumerable lives, the incalculable personal traits, endeavours and experiences, that have gone to make the Individualism of any strain of stock, and realising that just these factors of Individualism can have occurred in one line only of human ascent and can never be repeated, it becomes clear that summarily to extinguish any human strain, by arbitrary prohibition, would be to exterminate a unique branch of the great Life-tree, and thereby to deprive the Race of a specialised route of further ascent; a route which no other stock could supply. The fact that great families, with great histories and talents behind them, fall into decadence shows that even in decadent stock are inherences of greatness which might be recruited to greatness again. While apart from all this, the right of Parenthood, with the evolutionary impulse to character and faculty consequent upon the exercise of parental functions, is the birthright of every individual capable of fulfilling such. The counsel of Selective Parenthood is dangerous doctrine, indeed. Given Life, Nature by her methods of Disease is able to eliminate stock too deteriorate for, or beside her purpose. But she alone knows her purpose. And she alone can judge as to what is intrinsic Fitness for Survival. Selective Parenthood makes, moreover, for the elimination of those valuable object-lessons of inherited defect and disease, whereby Nature points her inestimable morals of healthy and disciplined living. For evasion, too, of those penalties and burdens in the care and maintenance of the Unfit, which a nation justly incurs by such social wrongs and maladministrations as are largely responsible for disease and defect. The doctrine of operative sterilisation is not only humanly repugnant but, in view of the psychological import of every physical function, it is essentially evil. X Some momentous morals of the Feminist trend are pointed by the Insect-world, which may be regarded as a devolutionary back-water, wherein Life is slowly ebbing toward extinction by fluctuating out in ever smaller, meaner, drabber, ineffective, pulseless and spectral existences--chill and teeming myriads unwarmed by the throb of emotion, unillumined by the light of Mind. Dust which, raised from dust by power of Life, has caught the trick of living, and goes on living and perpetuating, without cause or impulse other than age-old, time-worn mechanistic habit imparted by the state of living.
