Ignorance has been well represented under the similitude of a dungeon, where, though it is full of life, yet darkness and silence reign. But in society the bars and locks have been broken; the dungeon itself is demolished; the prisoners are out; they are in the midst of us. We have no security but to teach and renovate them.
Horace MannIn vain do they talk of happiness who never subdued an impulse in obedience to a principle. He who never sacrificed a present to a future good, or a personal to a general one, can speak of happiness only as the blind speak of color.
Horace Mann
