Knowledge is at once the manna and the medicine of our moral being.

Where crime is the bane, knowledge is the antidote.

Society may escape from the pestilence and may survive the famine; but the demon of ignorance, with his grim adjutants of vice and riot, will pursue her into her most peaceful haunts, destroying our institutions, and converting into a wilderness the paradise of social and domestic life.

The State has, therefore, a great duty to perform.

As it punishes crime, it is bound to prevent it.
