Ignorance is the curse of God; knowledge is the wing wherewith we fly to heaven.

The only good is knowledge and the only evil is ignorance.

Ignorance more frequently begets confidence than does knowledge: it is those who know little, and not those who know much, who so positively assert that this or that problem will never be solved by science.

Nothing in the world is more dangerous than sincere ignorance and conscientious stupidity.

The foundation of our Empire was not laid in the gloomy age of Ignorance and Superstition, but at an Epoch when the rights of mankind were better understood and more clearly defined than at any former period, the researches of the human mind, after social happiness, have been carried to a great extent, the Treasures of knowledge, acquired by the labours of Philosophers, Sages and Legislatures, through a long succession of years, are laid open for our use, and their collected wisdom may be happily applied in the Establishment of our forms of Government.

Human knowledge consists not only of libraries of parchment and ink - it is also comprised of the volumes of knowledge that are written on the human heart, chiselled on the human soul, and engraved on the human psyche.
