What, unless biological science is a mass of errors, is the cause of human intelligence and vigour? Hardship and freedom: conditions under which the active, strong, and subtle survive and the weaker go to the wall; conditions that put a premium upon the loyal alliance of capable men, upon self-restraint, patience, and decision. And the institution of the family, and the emotions that arise therein, the fierce jealousy, the tenderness for offspring, parental self-devotion, all found their justification and support in the imminent dangers of the young.
H. G. WellsThe crying sounded even louder out of doors. It was as if all the pain in the world had found a voice. Yet had I known such pain was in the next room, and had it been dumb, I believeโI have thought sinceโI could have stood it well enough. It is when suffering finds a voice and sets our nerves quivering that this pity comes troubling us. But in spite of the brilliant sunlight and the green fans of the trees waving in the soothing sea-breeze, the world was a confusion, blurred with drifting black and red phantasms, until I was out of earshot of the house in the stone wall.
