Jails and prisons are the complement of schools; so many less as you have of the latter, so many more must you have of the former. - Horace Mann

So much, then, my friends, is done, in the common and established course of nature, for the welfare of our children. Nature supplies a perennial force, unexhausted, inexhaustible, re-appearing whenever and wherever the parental relation exists. We, then, who are engaged in the sacred cause of education, are entitled to look upon all parents as having given hostages to our cause; and, just as soon as we can make them see the true relation in which they and their children stand to this cause, they will become advocates for its advancement, more ardent and devoted than ourselves.

I affirm, in words as true and literal as any that belong to geometry, that the man who withholds knowledge from a child not only works diabolical miracles for the destruction of good, but for the creation of evil also. He who shuts out truth, by the same act opens the door to all the error that supplies its place. Ignorance breeds monsters to fill up all the vacuities of the soul that are unoccupied by the verities of knowledge. He who dethrones the idea of law, bids chaos welcome in its stead. Superstition is the mathematical complement of religious truth; and just so much less as the life of a human being is reclaimed to good, just so much more is it delivered over to evil. The man or the institution, therefore, that withholds knowledge from a child, or from a race of children, exercises the awful power of changing the world in which they are to live, just as much as though he should annihilate all that is most lovely and grand in this planet of ours, or transport the victim of his cruelty to some dark and frigid zone of the universe, where the sweets of knowledge are unknown, and the terrors of ignorance hold their undisputed and remorseless reign.

No matter how seemingly unconnected with human affairs or remote from human interests a newly-discovered truth may appear to be, time and genius will some day make it minister to human welfare. When Dr. Franklin was once sceptically asked what was the use of some recondite and far-off truth which had just been brought to light, "What," said he, "is the use of babies?"
