There are not a few popular opinions, in regard to which it is useful at times to ask a question or two. For example, it is commonly thought that children must have what are commonly called “children’s epidemics,” “current contagions,” &c., in other words, that they are born to have measles, hooping-cough, perhaps even scarlet fever, just as they are born to cut their teeth, if they live.
Now, do tell us, why must a child have measles?
Oh because, you say, we cannot keep it from infection—other children have measles—and it must take them—and it is safer that it should.
But why must other children have measles? And if they have, why must yours have them too?
If you believed in and observed the laws for preserving the health of houses which inculcate cleanliness, ventilation, white-washing, and other means, and which, by the way, are laws, as implicitly as you believe in the popular opinion, for it is nothing more than an opinion, that your child must have children’s epidemics, don’t you think that upon the whole your child would be more likely to escape altogether?
