“That we shall use every discovery of science in the preservation of our children's health goes without saying; but we shall do more than this - we shall give them a free start, not loading them up with our own ideas and experiences, nor advising them to live according to our lights. We were burned in the fire here and there, but - who knows? - fire may not burn our children, and if we warn them away from it they may end by never growing warm. We will not even inflict our cynicism on them as the sentimentality of our fathers was inflicted on us. The most we will do is urge a little doubt, asking that the doubt be exercised on our ideas as well as on all the mortal things in this world.”
