They are less within than without the average home.

They are those that give the high death-rate of infants, the crippled limbs of children, the weakness of body and defectiveness of mind and feebleness or perversion of moral nature that make so many human beings unequal to life's demands.

They are the dangers, personal and social, summed up in the antitheses of "health" and "disease," of "normal" and "abnormal." Not that the dangers so indicated are new but rather that we are newly aware of them.

Not that savage or early civilized life had conditions more favorable to health and normality but that the easier modern conditions save alive many who in harsher times would have died in babyhood.

Moreover, we are beginning at last to set a standard, in ever-clearer outline, of what is health and of what is normality in physical, mental, and moral human life.
