Here appears a child plainly not normal, what shall we do with him? Shall we, as some have advocated, even from Spartan days, hold that the weaklings should be destroyed? No. In cultivating plant life, while we destroy much that is unfit, we are constantly on the lookout for what has been called the abnormal, that which springs apart in new lines. How many plants are there in the world to-day that were not in one sense once abnormalities? No; it is the influence of cultivation, of selection, of surroundings, of environment, that makes the change from the abnormal to the normal. From the children we are led to call abnormal, may come, under wise cultivation and training, splendid normal natures.

See, too, what a vast number of environmental influences have been at work in social relations, in climate, in physical surroundings. Along with this we must observe the merging of the vicious with the good, the good with the good, the vicious with the vicious.
