Ignorance breeds monsters to fill up the vacancies of the soul that are unoccupied by the verities of knowledge.

So, in the infinitely nobler battle in which you are engaged against error and wrong, if ever repulsed or stricken down, may you always be solaced and cheered by the exulting cry of triumph over some abuse in Church or State, some vice or folly in society, some false opinion or cruelty or guilt which you have overcome! And I beseech you to treasure up in your hearts these my parting words: Be ashamed to die until you have won some victory for humanity.

Deeds survive the doers.

Injustice alone can shake down the pillars of the skies, and restore the reign of Chaos and Night.

Every addition to true knowledge is an addition to human power.

Without undervaluing any other human agency, it may be safely affirmed that the Common School, improved and energized, as it can easily be, may become the most effective and benignant of all the forces of civilization. Two reasons sustain this position. In the first place, there is a universality in its operation, which can be affirmed of no other institution whatever... And, in the second place, the materials upon which it operates are so pliant and ductile as to be susceptible of assuming a greater variety of forms than any other earthly work of the Creator.

The object of punishment is, prevention from evil; it never can be made impulsive to good.
